In this book Rudebusch gives a lucid and engaging account of the philosophy of Socrates. Of course "philosophy of Socrates" is now something of a term of art, generally covering the content of a certain group of favored works of Plato (or parts thereof) that are thought to capture the spirit (if not the letter) of the historical Socrates. Rudebusch is rightly keen to emphasize the philosophical value of that content rather than its historical accuracy. Indeed one of the more refreshing aspects of his approach is his desire to look at the dialogues from what he calls an 'existential' rather than an 'academic' point of view -- that is, as containing themes that might actually be of vital importance for us today in our quest to live a good human life.

Equally refreshing is Rudebusch's refusal to play down the radical nature of some of Socrates' theses -- for example, that all the virtues are identical and amount to a kind of knowledge, and that such knowledge will bring us happiness. He is, moreover, keen to show that Socrates is able to provide compelling arguments for his positions, and that therefore they are ones we must take seriously. Overall, then, particularly for readers relatively new to these works (and, it must be said, for those not so new but a little jaded with an overly 'academic' approach) this is likely to prove an exciting and companionable volume. Rudebusch has an appealing voice -- that of the intelligent, committed advocate -- well suited to his material and to the aims of the 'great minds' series of which it is a part.

In some ways the book is quite conventional. Its view of which of Plato's works are to be regarded as 'Socratic' basically adheres to those dialogues that Vlastos influentially classified as early or transitional. This kind of classification goes back ultimately, albeit indirectly, to Aristotle's testimony, of which Rudebusch has a brief but judicious discussion (204-6). But there is a certain tension in Rudebusch's approach. If the objective is to give an account not of the historical figure 'but the great mind in the text' (xv) then why restrict oneself to those parts of the text deemed most historically faithful? If, on the other hand, historical veracity is one's aim, it is unclear (without at least a bit more defense) why Plato's reports of Socrates should be privileged over those of, say, Xenophon, who only gets brief mention. In a volume of this nature there is perhaps a limit on how much time can be spent on such methodological issues. But given Rudebusch's primary aim of explicating the Socrates we find in Plato's works one might have hoped for something a little more satisfying in terms of Plato's own art than the rather tired separation of one figure representing 'a portrait of the historical Socrates' (204) from another who, as 'a mouthpiece for the views of Plato himself' (ibid.), can be safely set aside when Socrates is the topic.

Once one has identified one's favored works, with the attendant awkwardness of treating, say, Republic Book 1 (as Vlastos did and as Rudebusch does) as essentially a separate Socratic dialogue, one identifies one's favored themes. Here too Rudebusch is to some extent conventional. Theses such as the so-called Unity of Virtue (not a term Rudebusch himself employs) and the sufficiency of knowledge for happiness have received microscopic analysis from scholars over the years. But it is a tribute to Rudebusch that he succeeds by and large in conveying the sense of strangeness and challenge that these indeed radical positions should still have for us. Welcome also is Rudebusch's emphasis on the religious aspect of Socrates (still rather underplayed in contemporary scholarship despite the sterling efforts of some) and on the centrality of love to Socrates' outlook. I found the distinction Rudebusch draws between 'needy' and 'giving' love as applied to the discussion of the Lysis an illuminating one, though not all of Rudebusch's nomenclature is quite so happy. Rendering the Greek dikaiosunē as 'righteousness' rather than the more usual 'justice', while certainly in this instance unconventional and consistent with the religious dimension, had the effect, for me, of obscuring rather than clarifying the sense of that term, though others may disagree.

What should we make of the radical theses that Socrates delivers? As with any philosophical position, the credence to be given to them must depend in large measure on how convincing we find the arguments adduced in their favor. So we must face the question of what to make of Socrates' arguments. Here, I think, Rudebusch draws something of a false dichotomy. He speaks (xii) of those readers who think there are obvious objections to the arguments, in which case we must regard Socrates as either having failed to see how poor his arguments were, or as putting them forward merely in jest. Or we must regard the objections as surmountable, so that contrary to appearances the arguments turn out to be compelling. Rudebusch takes the latter option, but he seems to have missed a viable alternative, which one might call the dialectical approach. Take the purpose of Socrates' arguments to be not to propound a particular philosophical position, but to show that his interlocutors' own thoughts on important issues are muddled and confused, and that they therefore need to devote considerably more critical attention to those thoughts than they have hitherto done.

As Rudebusch is of course aware (it forms a significant part of his account) this is pretty much how Socrates describes his own mission in the Apology -- the revealing to others of their unwitting ignorance. Why should we, then, suppose that Socrates is at all interested in expounding what Rudebusch calls on p. 98 'moral theory', especially given that Socrates is so insistent himself in the Apology that he lacks knowledge about moral matters? It is, I confess, a surprise to me that one such as Rudebusch, who signs on to the idea that certain favored dialogues are 'Socratic' -- works which tend to end in perplexity and to be characterized by Socrates' awareness of his ignorance -- should treat the establishment of a moral theory on Socrates' behalf as an interpretive desideratum.

Moreover there is a danger on this approach that one ends up tying oneself in knots, and I don't think Rudebusch entirely escapes this. For example, having taken the Unity of Virtue to be a tenet of Socratic moral theory, he then has to explain why in the Laches Socrates seems to hold as fixed that bravery is merely one part of virtue. Rudebusch's response is that this reflects a Socratic policy of using deliberate false leads (see in particular his Chapter 7, 'puzzling pedagogy') to expose an interlocutor's mental confusion. But now we have a rather ungainly combination: a figure who has a radical moral theory and compelling yet contentious arguments to support it, but who uses not these but a bunch of false assertions when actually working on an interlocutor. This, it seems to me, does not add up. If Socrates has radical positions to which he is committed and supporting arguments that are already apt to bamboozle, it seems both insincere and wasteful to peddle deliberately false lines instead. Of course one can argue that putting forward a hypothesis such as that bravery is (merely) a part of virtue, which an interlocutor is likely to accept, is dialectically more effective in exposing mental confusion than offering a more exotic thesis. But then it seems to me that the whole idea of false leads is beside the point. One's aim is to show that the interlocutor assents to ideas that are not mutually consistent -- something must be wrong and it is the task of further examination to discover what. But the falsity of a particular proposition, let alone the questioner's taking it to be false, is neither here nor there for the purposes of such a dialectical venture.

One might nevertheless have independent reason for thinking that Socrates does subscribe to particular moral tenets. One of the key exhibits for Rudebusch in this regard is the Protagoras, where Socrates certainly might be taken to be advocating in his own name the thesis that all of human excellence is to be identified with a kind of knowledge. On the other hand, the context is dialectically tricky, more so, I think, than Rudebusch acknowledges. The discussion concludes in puzzlement, with Socrates imagining the personified argument asking how Socrates can maintain that virtue is not teachable and yet is a kind of knowledge, while Protagoras maintains the converse. So it is prima facie unclear that Socrates ends the dialogue regarding "virtue is knowledge" as an unproblematic tenet of moral theory, or that it should be he rather than Protagoras who ought to espouse it.

Moreover when it comes to one of the main supporting planks for this would-be tenet, namely the argument that knowledge is sufficient for right action (that akrasia is impossible), there is rather less commitment expressed by Socrates than Rudebusch suggests. On one of the very few occasions that Rudebusch's rendering of the Greek may mislead the reader (his translations are on the whole excellent), he claims (44, 63-4) that at Protagoras 352e5-6 Socrates proposes 'to teach the world' what the phenomenon regarded as akrasia really is. But what Socrates actually urges here is that Protagoras 'try to teach' (epicheirēson . . . didaskein) people about it, albeit with Socrates' help (met'emou). So even where Rudebusch thinks he can find a straightforward statement of a position, the actual wording is, as so often with Socrates, less committal and more dialectically subtle than that. In light of his overall approach, it is surprising that Rudebusch chooses not to give the Gorgias, where I think it is arguable that at times we do get something like the setting out of a Socratic position (with a fierce urgency to boot), a chapter to itself, while the more nuanced Protagoras and Laches earn two each.

That said, one of the joys of studying Plato's Socrates is that one never quite succeeds in working out what he is up to. Although I have expressed some doubts about Rudebusch's reading of Socrates as a moral theorist, the experience of this book will be joyous for many readers, as it was for me. Rudebusch's advocacy of Socrates as a thinker who has much to tell us about the good human life is carried off with passion and grace, as well as an enviable succinctness and clarity. It is a treatment that I expect will succeed, deservedly, in winning over new advocates.

To write a compendium to the Cynics covering their history from the 4th century BCE to the 6th century CE and their huge and diverse influence from their beginnings down the ages to the present day is an unspeakable task. It requires competence over a vast time span, over many different periods and cultures, over not only philosophy but also history, politics, literature, religion (Jewish and Christian as well as pagan), and art, and it includes major Classical writers (Horace, Petronius, Lucian) and major European philosophers (Rousseau, Nietzsche). It also requires considerable discrimination in the use of the ancient evidence, extremely lacunose and varied as it is. Add the prospectus of this series, Ancient Philosophies: 'fresh and engaging introductions to the major schools of philosophy of antiquity . . . clear and rigorous presentations of core ideas . . . for students of philosophy and classics', to almost all of whom almost of all of this material will be new. Hence a need for a deft mixture of primary material and context or background, of basic information and critical analysis.

Desmond, well-informed author of the well-received The Greek Praise of Poverty: Origins of Ancient Cynicism (2006) (http://bmcr.brynmawr.edu/2006/2006-08-05.html), writes, indeed, freshly and engagingly, and his wide stylistic range includes colloquialisms, jokes and nice turns.

The glossaries, bibliography, index and the wide-ranging and detailed 'guide to further reading' are excellent, the last of value to specialists as well as beginners. The basic organization is coherent (if problematic in some respects). The overall movement is chronological: chapter 1 provides potted introductions to the main Cynics and others more or less influenced by Cynicism, while chapters 2-6 treat major themes and concerns, with recurrent movements from negative to positive.

Shortcomings include constant documentary overload; much disproportion, repetitiveness and overlapping; some self-contradiction; insufficient referencing and cross-referencing; a rather capricious relationship between text, notes within the text, endnotes and 'further reading'; unexplained or over-allusive allusions; some disconcerting Latin and English solecisms, and some very old-fashioned historical perspectives (which I do not illustrate but which will disturb historians). The book is too long for its contents; disciplined pruning would have allowed much additional matter. Desmond's readers should have been more stringent.

The introduction takes the Diogenes of the encounter with Alexander as representative, summarizes his thinking and behavior as well as different ancient reactions, distinguishes between ancient Cynicism and modern cynicism, outlines positive modern verdicts on the former, distinguishes between different types of cynicism, and signals the main sources. The exposition is over-long (e.g. on modern cynicism [2-3]), too allusive (the largely unexplained 'most important sources' [5-6] would baffle most students), and careless in expression ('various dialogues of Lucian, especially the Cynicus once (erroneously) attributed to him' [5]). The historicity of the encounter (well defended by Hammond, Sources for Alexander the Great [1993] 28) seems to be accepted (7), but without rigor. Yet the question is important on many levels: Diogenes' attitude to worldly rulers; his practical response to them; his frankness, bravery and culture of nature; Alexander's knowledge of contemporary philosophers; and Onesicritus' portrayal of Diogenes and of Diogenes' role in his portrayal of Alexander.

Desmond never faces up to these kinds of historical questions, which affect assessment alike of the substantiality, impact and reception of Cynicism. Introductions may perhaps legitimately flag arguable conclusions, though in the case of such a controversial topic as Cynicism an initial tabula rasa would in my view have been the better course. At any rate, here already, unequivocally, Cynicism is a 'philosophy', 'Diogenes . . . the first . . . "dog" '(5), Cynics were not 'mere shameless "dogs" ' (4), but 'astonishingly optimistic regarding human nature' (3), and 'Cynicism . . . was both a single outlook and extraordinarily varied' (5) (hence the usual sub-divisions, used with scare quotes, 'hard', 'soft', 'literary', etc.). While Desmond subsequently produces piece-meal arguments for most of these claims, which (in my view) are more or less correct (although I believe that, like others, he exaggerates Cynicism's 'extraordinary variety'), he never confronts the single biggest question about Cynicism (already in ancient tradition, explicitly at D.L. 6.103, and still debated): whether it qualifies as a philosophy in any sense rather than just a way of life. While the two can cohere, 'right living' being the goal of ancient philosophy generally (Macleod, JRS 69 [1979] 16-27), such 'living' requires some underlying thinking. That Cynicism had some such thinking is most easily (though not solely) demonstrable through reconstruction of important Cynic texts, written, as they were, in serio-comic style. Desmond, naturally familiar with such source criticism (263), never pursues it, convincing though some of it is (though he occasionally reconstructs chains of thought [e.g. 157]).

Hence much blurring of different categories of evidence and a major structural problem for the book: the exposition of ancient Cynicism ends with Cynic cosmopolitanism, for which the key text is Diogenes' Politeia, reconstructible from D.L. 6.72 (as Desmond seems to concede [186]). That work, however, should come at the beginning, because it is also key for understanding all Diogenic Cynicism and of most of its developments and modifications. Failure to acknowledge such basic material produces further confusions: between the questions of the uniformity of Cynicism over the ages and of the unity of Diogenic Cynicism (6-7; 245 n. 1); and concerning that very unity (formally different values [245 n. 1] belong within a single coherent 'package'). It also inhibits clarification of Cynicism's overall logic, which combines 'thought' (necessarily, given other Cynic assumptions, minimalist) with 'performance' or 'what works', the latter both as a verifiable solution for oneself and as a demonstration for others. Further, especially given the prospectus, consideration should have been given to the question of whether Cynicism qualifies as a 'school' (answer: yes and no). Finally, the question of vulgarization and bowdlerization of the record should have been trailed: Höistad held that the image of the historical Diogenes was grossly vulgarised, and, though the claim is untenable, it merits notice as that of a major Cynic scholar; conversely, bowdlerization and idealization of the historical Cynics is a persistent trend in the tradition (as, again, Desmond knows [75, 268] but generally underplays).

The very useful first chapter begins with a historical survey of Greece, Macedon and Rome, distinguishes between proto-Cynics (legendary, from other cultures, Socrates), 4th century 'canonical' figures, Hellenistic 'literary' Cynics, and the eclectic Roman period, down to the Christian Fathers.

Some comments on details in Chapter 1:

While Desmond rightly stresses the schizophrenic appearance of Antisthenes' thought, 'the ancient tradition' that 'Antisthenes was the first Cynic', though dominant, is not 'unanimous' (13). Antisthenes' obvious influence on Diogenes does not require a 'personal link', to which the powerful objections, as Desmond does not say, are chronological. Antisthenes' strong continuing presence within the Cynic tradition (greater than recognized at 18, 157) is noteworthy: see Brancacci in Swain (ed.), Dio Chrysostom: Politics, Letters, and Philosophy (2000), 240-60; Moles, JHS 125 (2005) 112-38 (on Dio 13).

D.L. 6.71 shows that the motto 'deface the currency' was adopted not just by 'later Cynics' (20) but by Diogenes himself. Desmond here (20) takes Aristotle's 'dog' (Rhet. 1411a24) as Diogenes, whereas 246 n. 10 favours Antisthenes (so M.-O. Goulet-Cazé). On the question of Diogenes' writings, Desmond begins (22): 'other rumours impute various writings to Diogenes' and concludes: 'perfect precision about Diogenes' sayings, writings, movements and life is not attainable. What is more important . . . is the personality of the man' (as if this could be established independently?). On the question of Diogenes' (fictitious) enslavement: 'it may well be the case that as an exile Diogenes was enslaved at some point' (22). Such evasions frustrate scholarly progress. As for Hipparchia, 'later denigrators sneered that [Crates and Hipparchia] had sex in public' (27). In fact, this well-attested 'dog marriage' perfectly enacts Diogenic sexology, as long ago demonstrated by Rist, Stoic Philosophy (1969) 61 ff. (which Desmond knows [271]).

Onesicritus's Alexander history was not formally a 'biography' (30). Desmond's discussion of Onesicritus' account of his visit to the Gymnosophists is under-developed, nor does he register the sheer chutzpah of Onesicritus' 'cynicisation' of Alexander (on both: Moles in Laks and Schofield, Justice and Generosity (1995) 144 ff.). Bion's 'biography' is obviously partly based on Diogenes' 'biography' (OCD³, 243). The discussion of diatribe is rather generalized and could have been improved by consultation of OCD³, 463; undoubtedly, Bion (and Zeno) wrote works with that title, and Horace represents his Satires as belonging to the 'Bionian', 'Cynic' and 'serio-comic' 'genre' of 'diatribe' (Epistles 2.2.60; Satires 1.1.13-14).

As Cynic, politician and law-maker, Cercidas (35) deserves fuller treatment, especially as fairly substantial fragments survive. Desmond's discussion of Oenomaus does not register his clear philosophical and literary imitation of Diogenes (a further consequence of failure to engage with the question of Diogenes' writings), as demonstrated by Hammerstädt, whom Desmond references. Demetrius was hardly 'the first "true" Cynic after a hiatus of some two hundred years' (50); see Moles, JHS 103 (1983) 120 ff.

Dio Chrysostom did not criticize his friend Titus 'for having a homosexual relationship with a boxer' (57): Orr. 28 and 29 are encomiastic. Characteristically, neither here nor elsewhere, does Desmond commit himself on -- still less, argue out -- the key question of whether Dio spoke the Kingships to Trajan. On Dio 13, a major (partly) Cynic text, see Moles, JHS 125 (2005) 112 ff. Desmond's general emphasis on the importance of Cynicism to the Stoic Epictetus (59), as against scholars such as Brunt and Long, seems to me correct and important, though space should somewhere have been found for full treatment of 3.22, another key text on Cynicism, powerfully analyzed by Schofield, Philosophical Quarterly 54 (2004) 448 ff. (unreferenced).

Desmond's extended analyses of Lucian, here (55-6, 60-7) as elsewhere, are a major strength of the book. Lucian's 'digging-up' of 'Bion' (61; Bis. Acc. 33) alludes to 'philosophical and literary reincarnation' (e.g. Woodman in A.J. Woodman and D. Feeney [eds], Traditions and Contexts in the Poetry of Horace [2002], 53 ff.) and to Bion's punning both on his own name as 'life' (Moles in S. Harrison, The Cambridge Companion to Horace [2007] 178) and on the Cynic 'way of life'. Desmond (67-9) ignores Clay's disturbing (but, I think, untenable) claim (ANRW II.36.5, 3425) that Lucian invented Demonax.

Chapter 2 is also very useful (though too long), and considers the topic under various headings (clothing, housing, diet, etc).

Some comments on details in Chapter 2:

The tentative treatments of Diogenes and cannibalism (86) and the community of children/women/men (95, cf. also 257 n. 10) are further casualties of Desmond's abjuration of source criticism. The 'sex' section (89) also needs Diogenes' Politeia, also the source of Diogenes' 'mischievous syllogism' (103; D.L. 6.37; 72).

The interesting discussion of Cynic views on slavery could use Brunt, 'Aspects of the Social Thought of Dio Chrysostom and of the Stoics', PCPS 19 (1973) 1 ff.

Unfashionably (but, I think, rightly), Desmond follows Rostovtzeff and Baldwin in discerning real social protest in the Cynicising Lucian (100).

To my mind, Desmond (101 and elsewhere) over-emphasizes Cynic 'opportunism'. The motto 'use the things that are present' (both spatially and temporally) allows a certain (small) moral relativism, then greatly developed by Bion under Aristippus' influence (cf. OCD³, 243; Horace, Epistles 1.17, reads this aright).

The wide-ranging discussion of Cynic 'language', including gesture (122 ff.), might also consider: (a) Bosman's 'Selling Cynicism: the Pragmatics of Diogenes' Comic Performances', CQ 56 (2006) 93 ff.; (b) the likely influence of Antisthenes (cf. 18, 157, 255 n. 53); (c) the fact (pace 123) that some of Diogenes' jokes play, precisely, on the 'instability of the sign', hence, presumably, further incentive towards a philosophy of 'what works'.

In chapter 3, necessary background (different conceptions of nature; other philosophers' interpretation of the motto; anticipations of Cynic thinking) becomes foreground and for far too long, though useful points emerge (e.g. similarities with the Epicurean 'life according to nature' [147]), as, eventually, does the right conclusion: Cynics interpreted the motto primitivistically (160-1; 257 n. 10). Fifty years ago, simple quellenkritik (Brown, Onesicritus [1949] 149 n. 152) proved Diogenes' imprimatur here.

The same criticism applies to chapter 4, although, again, there are interesting things. Following Relihan, Desmond interprets Petronius' Menippean Satyricon as a Cynic novel, whose Cena dramatizes reversals of Fortune, from which the Cynic-like wanderers Ascyltus and Encolpius escape (169-71). This interesting and coherent interpretation (again) harnesses Cynicism to serious social criticism, although Petronian scholars seem unimpressed. The comparison of the self to an actor is first attributed not to Bion (181) but to Aristippus (D.L. 2.66, cf. Horace, Epistles 1.1.19; 17.23-4). Its great importance to the Stoic Panaetius (Cic. Off. 1.107 ff.) should be signaled.

Chapter 6 finally tackles Diogenes' Politeia, which (pace 186) is perfectly compatible with Crates' Pera. Cercidas should have appeared here. Desmond makes interesting observations about the Cynics' 'democratic populism' (188-92). On the other hand, philosophical kingship theory is not unproblematically Cynic (196), as Desmond later admits (199); see also on Onesicritus above. For the rest, Desmond's discussion of Cynic cosmopolitanism, giving it great positive value, largely follows positions I myself have maintained. One false note is the claim that Epicureans were not missionary philosophers (203).

Chapter 6 is inevitably a highly selective gallop, with individual stops, from Stoicism to Sloterdijk, and, finally, Navia, both of whom argue for the value, even the necessity, of Cynic thinking in today's world, thereby ending the book on an uplifting note. Many of the gaps are plugged in the 'further reading'; see also now L. Shea, The Cynic Enlightenment: Diogenes in the Salon (2010).

Some comments on details in Chapter 6:

Desmond rightly stresses that later Stoics generally retreated from Chrysippean intellectualism to an ethical core exemplified by an idealised Cynicism (211), though he omits Panaetian hostility and Seneca's interesting ambivalences.

Although 246 references Gigante's Cinismo e Epicureismo, I would have liked consideration of the superficially more surprising Cynic influence on the Epicureans, which seems to me considerable, despite the fact that Epicureans, from Epicurus on, reviled the Cynics, presumably on the principle of 'that man did me a good turn ten years ago and I've hated him ever since'.

The pages on claimed relationships between Cynicism and early Christianity should have 'main-texted' diatribe and Cynic influence on Paul (convincingly expounded by Malherbe, referenced on 272). The discussion of the 'Cynic Jesus' controversy balances arguments conscientiously, before tilting to the negative. Like most such discussions, however, it envisages only two possibilities: Jesus the complete Cynic or a Jesus wholly untouched by Cynicism, whereas the case for some influence has, I believe, some good arguments. The long discussion of later Christians' ambivalence to Cynics culminates with Leontius' Life of Symeon (7th century), where Desmond is unduly noncommittal about Krueger's claim of a systematic analogy with an unreconstructed Diogenes: remarkable final proof of the longevity and canonicity of Diogenic Cynicism.

Criticisms allowed for, this book remains a considerable achievement. It unites rare diligence with unobtrusive intelligence and independence of judgment. Its coverage is immense. Anyone who works on Cynicism at any level will find it extremely useful.

Our current day most successful theories are gauge theories. On the one hand there are the quantized Yang-Mills theories that describe non-gravitational interactions. On the other hand there is general relativity (whose quantum version is still under construction) which describes gravitational interaction. These theories are called gauge theories because their standard formulation contains unobservable and hence apparently redundant elements. In the philosophical community, the gauge aspects of Yang-Mills theories have received far less attention then those of general relativity. Healey's latest book -- winner of the 2008 Lakatos award -- is therefore remarkable in that its main focus is Yang-Mills theories. Most of this book concerns a careful and detailed study of the ontological implications of both classical and quantized Yang-Mills theories. In particular, a non-localized ontology is defended in which the basic ontological variables are the holonomies associated with loops in space-time.

In the first half of the book (the first four chapters), Healey considers classical gauge fields. In classical electromagnetism, the gauge field interacts with point-particles and a natural ontology is given by the point-particles and the electric and magnetic field. When the classical gauge field is instead coupled to a quantum particle (described by a wave function), a new effect arises, namely the Aharonov-Bohm effect, which seems to call for a revision of the classical ontology. Of course, by introducing a quantum particle one actually also needs to deal with the interpretational problems of standard quantum theory. Healey circumvents these problems by considering possible ontologies only for gauge fields, without much consideration for the ontology of the quantum particle. These interpretational issues are reconsidered in some detail in Chapter 8, in the context of quantized Yang-Mills theories, where they are unavoidable.

While it is definitely a good idea to disentangle gauge issues from interpretational issues, I believe that abstaining from fully incorporating the matter degrees of freedom in the ontology leads to other complications (as I will indicate below). I believe a better approach would have been to consider also a completely classical theory of interacting gauge fields with matter fields. For example, the matter field could be a Schrödinger field or a Klein-Gordon field. Such a theory would of course empirically be completely inadequate, just as classical non-Abelian Yang-Mills theories are, but I believe that a discussion of its hypothetical ontological implications would be just as instructive as Healey's discussion of the latter theories. As with the classical non-Abelian Yang-Mills theories, one could assume that the hypothetical empirical content lies in the gauge invariant quantities. As such, there would also be an Aharanov-Bohm type effect (the "charge density" would obtain a fringe shift), so that much of Healey's arguments would immediately carry over.

Healey considers three possible types of ontology for classical gauge fields (first for electromagnetism in Chapter 2, and then for general Yang-Mills theories in Chapter 4):

• "The no gauge potential properties view": the ontology is given by the field strength (which Healey non-standardly calls the gauge field) and not by the gauge potential.

• "The localized gauge potential properties view": the gauge potential makes up the ontology, or some other (yet to be determined) quantities that are associated to arbitrarily small neighbourhoods in space-time and that can be derived locally from the gauge potential.

• "The non-localized gauge potential properties view": the quantities that make up the ontology can be derived from the gauge potential, but are not necessarily associated to arbitrarily small neighbourhoods in space-time.

Healey presents two arguments against the first view. First, this view implies action at a distance. This follows from the Aharonov-Bohm effect, where a magnetic field confined to a localized spatial region still has an effect on the interference pattern of a quantum particle that passes outside that region. Second, in the case of non-Abelian Yang-Mills theories, there exist gauge inequivalent gauge potentials that give rise to the same field strength in a simply connected region. So the field strength at that region would not completely capture the gauge invariant content associated to that region.

The second view is considered in more detail, with distinction of various approaches (including those of Leeds, Maudlin and Mattingly), but is finally rejected, basically on the ground of underdetermination: gauge equivalent potentials would yield different properties that can not be distinguished by observable facts.

After having rejected the first two possible views, Healey argues in favor of the third one. In particular, Healey defends a holonomy interpretation, whereby the ontology is given by the holonomies associated to loops (images of oriented closed curves) in space-time (these can be constructed from line integrals of the gauge potential along closed curves). While these quantities relate to extended regions of space-time, they do not imply non-local action. In the case of electromagnetism, which is an Abelian Yang-Mills theory, these holonomies are gauge independent. In the case of non-Abelian Yang-Mills theories, the holonomies are actually not entirely gauge invariant. Moreover, they also depend on the choice of base point on the loop. Healey seems to argue these issues away by noting that the quantities transform "covariantly" when also the wave function of the quantum system is taken into account.

It seems to me that, despite Healey's apparent arguments to the contrary, the base-point dependence and the gauge dependence of the holonomies in the non-Abelian case may still lead to objections of the type Healey raised against the second view. Healey also considers the Wilson loop, which is just the trace of the holonomy, and which is completely gauge independent and independent of the choice of base point, but dismisses it on the ground that it doesn't propertly take into account the interaction with the matter field. This is indeed a problem, but I don't take the message of it to be that the Wilson loop should be rejected, but rather that its notion should be suitably extended to include matter fields. Healey actually describes just such an extension in Section 7.4 (in the context of loop quantization), where quantities are also associated to open paths. These are constructed from the holonomy along the path and fermion fields at the end points, and seem adequately to take into account the fermionic degrees of freedom. (Healey spends some time on the complications in constructing such quantities, but such constructions seem to arise naturally in the Weyl representation of the Dirac matrices; see for example [1] and references therein). Maybe including the matter degrees of freedom in this way leads to some complications for some interpretations of quantum theory, but they seem completely adequate in the context of a completely classical field theory. But that being said, the Wilson loop approach would have the same metaphysical implications as the holonomy approach. It would also yield a non-localized ontology that evolves in a local way.

By considering an ontology also for the quantum particle (or a classical matter field), it would also be clear how the holonomies act on the particle. As for now, Healey states that the holonomies do not act on hypothetical localized phase properties of the wave function, but rather on some yet to be determined non-localized phase properties along a loop (see for example p. 127). This account is not only a bit vague, it might also change for an ontology that properly takes into account the matter degrees of freedom (as seems to be the case for the generalized Wilson loop approach).

As Healey indicates in Section 3.1.2, the holonomies (as well as the Wilson loops) contain all the gauge invariant information contained in the gauge potential. This is an important kinematical result. If the hololomies are taken to be the basic quantities, one should also express their dynamics without reference to gauge potentials. Unfortunately this problem is not discussed by Healey.

It is also notable that in rejecting the second view, Healey does not appeal to the indeterminism that generally arises when taking the potential to represent physical reality. For example, the equations of motion for the gauge potential do not yield a unique solution given initial data, but rather a class of solutions that are all related by a gauge transformation. Since these solutions are observationally indistinguishable, there seems to be an unnecessary surplus structure. However, Healey does not appeal to this indeterminism of the equations of motion to reject the second view (although he mentions it in passing on p. 56), but rather to an underdetermination of another kind. This is illustrated by Healey's discussion of Mattingly's proposal of a priviledged vector potential, called the "current field". This field can be expressed as a gauge invariant function of the charge current (which is itself gauge invariant). Since the current field is gauge invariant, there is deterministic evolution. I take Healey's main argument against this proposal to be that other fields could have been chosen that would observationally be indistinguishable from the current field and would still satisfy all the desired properties. These other fields could be obtained from the current field by what merely looks formally like a gauge transformation. However, it is unclear to me how Healey's holonomy interpretation (or a Wilson loop interpretation) could be shielded against a similar objection. One could always consider different non-localized ontologies that would observationally be indistinguishable from Healey's ontology (though these would not relate to each other by what formally looks like a gauge transformation).

After having considered classical gauge fields, Healey devotes the second half of the book to their quantized counterparts. In Chapter 5, Healey first considers different routes to obtain a quantum theory from classical Yang-Mills theories. One approach that also should have consideredin this chapter, but wasn't, is reduced phase space quantization. In this approach, which is briefly mentioned in Section 6.5, the gauge degrees of freedom are first eliminated, with the remaining degrees of freedom making up the reduced phase space, and then the theory is quantized. See, for example, [2] for some discussion of this approach.

In chapter 6, Healey considers the empirical import of gauge symmetry. In particular, some interesting features of quantized Yang-Mills theories are discussed, such as the Higgs mechanism, theta-vacua and anomalies, some of which still involve challenging conceptual questions.

Then, in Chapter 7, loop representations are considered, within the context of canonical quantization. In those representations the quantum states are functionals of loop variables (which are constructed in an overcomplete basis of Wilson loops). The virtue of these representations is that the gauge freedom is completely eliminated (just as in reduced phase space quantization). Healey considers the question of whether such representations might yield other quantum theories than the one that arises in the standard Fock representation. Different representations of the operator algebras might yield inequivalent quantum theories. This might allow the resulting quantum theories to be experimentally distinguished. And an experimental bias towards a theory that is obtained from a loop representation could support a loop based ontology within certain interpretations of quantum theory.

The various interpretations of quantum theory and their ontological implications for Yang-Mills theories are considered in Chapter 8. As Healey rightly notes, this is only an initial survey. Even though one can broadly distinguish the interpretations, such as Everettian or de Broglie-Bohm type intepretations, the ontological implications may still depend heavily on the details of the approach. For example, Everettian interpretations take the quantum state to represent the ontology, but there are various ways in which this quantum state can be understood: as just a state in a Hilbert space, or as a state in some preferred basis (for example in a loop representation), or as yielding states on space-time (see for example [3] for a discussion). Also in interpretations that have more ontology than just the quantum state, like de Broglie-Bohm theory or certain versions of collapse theories, there seem to be a variety of options. Some of these will incorporate an ontology that is similar to a possible ontology for classical Yang-Mills theories. For example, some might admit a holonomy interpretation. But one also has approaches where there is nothing like that. For example, in Bell's de Broglie-Bohm-type model for lattice quantum field theory [4], the ontology in space-time is given by the "fermion numbers" on the lattice sites and there is nothing representing the gauge degrees of freedom.

To conclude, Healey's book is a major achievement that will undoubtably serve as a valuable reference work as well as stimulate further debate and research. Healey intended the book to be self-contained, with extended appendices serving this goal. Nevertheless, some parts may be hard to follow without some background knowledge or without consultation of the original literature.

To the casual reader, the title of this book may seem ironic, oxymoronic, or, worse still, a joke. After all, Machiavelli is commonly regarded as the quintessential example of an amoral, even immoral, proponent of Realpolitik, authorizing deception and violence as legitimate political tools. But Benner's book is intended to dispel the illusions of the casual reader, and she is very serious indeed about the meaning of her title (to the point that there is no subtitle). Her aim is to extract and reconstruct from Machiavelli's "main political works (the Prince, Art of War, Florentine Histories and Discourses)" (p. 6) -- with occasional nods to his poetry and other "minor" writings -- a coherent set of moral principles and to demonstrate how these were consistently applied by him to salient issues of public affairs. Her reading yields an innovative and stimulating interpretation of a notoriously difficult (even slippery) author that is meant to reveal his distinctive contribution to philosophical concerns. Benner's insights are often surprising and challenging, and not always convincing (about which more below), but are definitely worthy of careful consideration. This big book makes big claims and supports them with a plethora of textual evidence.

It is beyond the scope of the present review to attempt a thorough summary of the complex arguments on which Benner builds her case. Rather, I will highlight what I take to be her two main (and interrelated) claims. First, she ascribes to Machiavelli an individualistic ethics that she explicitly identifies as deontological in character and that she regards as logically prior to and the foundation for his political ethics. According to Benner, Machiavelli's moral precepts are rooted in his conception of human agency as "bounded" and responsible: he posits that human nature generates a capacity for choice and action that permits people to overcome external forces (such as "fortune") in order to realize tangible moral goods. Primary among such goods, she asserts, is justice. In Chapter 8, she seeks to demonstrate that Machiavelli articulated across the range of his writings a cogent conception of justice -- where justice is understood to be the acceptance of the worth and dignity of other humans who also possess freedom, even (or especially) if they are less well positioned to realize their wishes -- as the deserving object of the human will. This view of justice as tied to human volition forms, in turn, the basis for Machiavelli's preference for republican institutions, in which the common good, embodied in law, is authorized by popular consent (see pp. 282-285). As Benner sums up her thesis in her concluding remarks,

the most basic principles of good [political] order are also principles of justice. And a proper understanding of justice takes account of the claims and perceptions of all parties, considered as equally free agents whose power of authorization deserves respect, even if some are much weaker than others. This, I submit, is the . . . core 'teaching' of all Machiavelli's political writings (p. 484).

Benner's Machiavelli does indeed forward a "political ethics," with emphasis on the latter word rather the former, in contrast to the standard interpretation. Morality, conceived as decisions and conduct limited by recognition of the legitimate claims of one's fellow moral agents, constitutes the best (and perhaps only true) foundation for political life, where "best" is understood in a double sense of both morally defensible and politically secure.

On the basis of her version of Machiavelli's core teaching, Benner reinterprets many of the familiar terms of his moral discourse. Virtù, for instance, comes to be closely aligned with more conventional conceptions of virtue and free will: "modes of action that deserve to be called virtuouso are by definition modes that recognize the necessity to respect constraints or limits (termine)" (p. 215). Likewise, ambizione is viewed not as a uniformly positive quality of human action, but rather as a natural disposition in need of careful regulation through institutional and legal remedies (e.g., pp. 378-379). Ambition stands in contrast to virtù to the extent that it potentially knows no bounds or limits. And the (in)famously Machiavellian theme of "ends-justify-means" must be qualified by prior examination of whether the means are themselves just (see pp. 340-343). The warrant for Benner's radical restructuring of Machiavelli's moral language derives from the second major facet of her overarching argument, namely, that his ethical principles are heavily indebted to the Greek tradition of thought as found in the works of Plato, Thucydides, Plutarch, and Xenophon, as well as in some of their Latin imitators. This claim is defended systematically in Chapter 2, with many further parallels elucidated throughout the entire book (often in the footnotes). In particular, Benner reads Machiavelli as a kind of Socratic, dialectical thinker whose doctrines cannot be taken at face value, but who instead must be read "against the grain," as a genuine philosopher seeking "to challenge, exercise, and improve readers' capacities to make discriminating moral and political judgments" (p. 484; see pp. 485-486). Thus, Machiavelli is seen to champion a Greek style of thinking and writing that is "self-critical" rather than "self-celebratory" (pp. 30-37), in apparent contrast to the manner typical of the Romans. Machiavelli's principal values are, in Benner's estimation, values shared with Greek antiquity. She consequently proposes throughout the book to filter Machiavelli's moral vocabulary through the ethical framework and language of classical Greece.

If Benner's account of Machiavelli looks barely recognizable to his present-day casual readers, let alone to recent serious scholars of his thought, she is unconcerned by this. Instead, she points, for precedent, to many members of Machiavelli's earlier audience -- including Gentili, Francis Bacon, Harrington, and Spinoza -- to support the position that the Florentine was, first and foremost, a moral philosopher of great power (pp. 2-4). To the extent that she does not offer an extensive examination of why these thinkers found Machiavelli to be worthy of their company, or even of how they themselves conceived the nature of moral philosophy, this assertion smacks of argumentation from authority and thus is unpersuasive. Still, one can perhaps never be reminded too often that Machiavelli has always been read from a variety of perspectives -- a historical claim much better documented, for example, in Sydney Anglo's magisterial 2005 book Machiavelli -- The First Century.

I am concerned, however, about Benner's highly selective and somewhat idiosyncratic use of the large body of more current secondary scholarship on Machiavelli. Much of the literature with which she engages -- such as work by Cassirer and Meinecke, and even Strauss, Pocock, and Skinner -- while highly influential in the past, is now recognized as being (seriously) deficient or incomplete. Benner's appeals to these sources give the appearance that she is sparring with straw men in contraposing her own interpretation to that of others -- her targets are too easy to knock down. Her lapses in reference to important research of the past thirty or so years are hard to understand: Harvey Mansfield, Sebastian de Grazia, Maurizio Viroli, and Mikael Hörnqvist receive some well-deserved (albeit passing) attention, but many authors included in the bibliography do not seem to have been engaged much (or at all) in the volume. Other important interpreters of the last generation (such as Mark Hulliung and Hanna Pitkin) as well as current ones (for instance, John McCormick's many articles on Machiavelli's populism and related topics, Paul Rahe's Republics -- Ancient and Modern, Anthony Parel's Machiavellian Cosmos, or any of the many relevant papers on Machiavelli by diverse scholars that have appeared in the leading journals History of Political Thought, Journal of the History of Ideas, and Review of Politics) have not merited even bibliographical citation. I am fully aware of the sheer volume of secondary writings on Machiavelli, and it is doubtful any scholar can be held responsible for mastering them completely. Yet the way in which the preceding literature is or is not brought to bear on the arguments of this book has, in my opinion, the effect of distorting the record and, at times, of making Benner's interpretations appear more innovative or original than they actually are. I do not believe, therefore, that I am quibbling.

A not unrelated objection arises from Benner's historical claim that Machiavelli's ethical principles rely upon his understanding and appropriation of Greek sources. The question of the extent of the Florentine's knowledge of Greek language and of Hellenic and Hellenistic texts (even in Latin or Tuscan translation) is an open one, as she admits. Indeed, her case for the view that Machiavelli was in thrall to the Greeks (presented especially on pp. 9-10) is weak and inferential at best, as her sometimes defensive tone about the topic (see p. 489) seems to reflect. Perhaps more importantly, Benner's conception of who counts as a member of the "Greek" tradition seems arbitrary: Aristotle is largely shunted aside; nor do I find any mention at all of either Stoicism or Epicureanism, two important and influential schools of Hellenistic philosophy, both in antiquity and in the Renaissance. A different set of choices about which texts and philosophies count as "Greek" would have generated a quite different interpretive scheme. In any case, it does not seem necessary for Benner to rely on the historical argument about the Greek background to Machiavelli in order to sustain her case for the moral precepts guiding his thought, given the considerable weight of the textual evidence from his corpus that she uncovers. Thus, the historical dimension of the book becomes a needless distraction from the defense of her philosophical thesis.

Another concern stems from the hermeneutical premises of Benner's textual interpretation. She constantly employs an approach that distinguishes "superficial" from "careful" readings and readers, refers at key moments to Machiavelli's "dissimulation," and alludes to "clues" and "hints," as well as to meanings that exist "between the lines" -- in sum, she draws on techniques recognizable to scholars of political theory as modes of "esoteric" interpretation (a hermeneutic most closely associated with Leo Strauss and his acolytes). Indeed, Benner admits as much in her conclusion when she "agrees" with Strauss that Machiavelli's texts "can never simply be taken at face value" (p. 490; emphasis added). Never? Really? And how do we know precisely? The Straussians at least have a highly developed rationale for why political authors must use esoteric means to express themselves, which emerge from the supposedly "dangerous" character of their philosophical truths, if expressed openly, in the context of political power. By contrast, Benner gives us no strong reason to prefer esoteric readings that distort and disfigure the surface meanings of texts in order to point to some deeper truth, except for Machiavelli's alleged devotion to a Socratic model of philosophical inquiry that is itself imputed and not explicitly on display in his texts. The resulting hermeneutic, not to put too fine a point on it, might best be termed "Strauss lyte."

One need not hold to a strictly historical interpretive approach of the Cambridge School variety, which insists that the author's intentions in relation to the ideological and political context are determinative of a text's meaning, in order to recognize that reasonable standards of historical and intellectual plausibility ought to apply. When, for example, Benner asserts that, despite all of Machiavelli's praise for Roman republican institutions and "orders," he "really" rejected the Roman way of life quite thoroughly and profoundly (pp. 475-478), it seems that we have surrendered those reasonable standards. Similarly, while her assertion that Machiavelli might have embraced a view of "conceptions of truth and knowledge that are non-dogmatic and critical, but entail the rejection of extreme skepticism" (p. 126) seems to me to be exegetically plausible, Benner's assertion depends upon her somewhat tortured understanding of how Machiavelli read the Greek philosophers and historians. A more direct and feasible interpretation would link this view to Cicero's moderate Academic skepticism, with which the Florentine was doubtless familiar. Cicero is, after all, often mentioned (usually positively) in Machiavelli's writings (unless, of course, these endorsements were themselves a feint).

In sum, once we are willing to accept that what an author and her/his writings explicitly state is the precise opposite of what is meant, or that their meaning depends upon an unsubstantiated set of intellectual connections, a kind of interpretative anarchism (of the Alice in Wonderland variety) comes to the fore. This is the path down which Benner leads us, and it strikes me that it inherently diverges from her view of Machiavelli as a principled moral individualist of the deontological variety. If she truly believes that Machiavelli's most cherished doctrines are antithetical to what is stated in his writings, then a single "true" (or even better) reading (the quest for a "core" doctrine in which Benner claims to be engaged) is itself rendered impossible. If there are no criteria for judging between competing readings, because every statement potentially means something else (and who knows which one to take at face value?), then, in words of Cole Porter and Paul Feyerabend, "anything goes" (or, perhaps more aptly, "everything the traffic will allow," with apologies to Irving Berlin). In fact, I do not think that Benner needed to go down this road at all. Without the "hocus pocus" hermeneutical approach, her book still gives us very good reasons for thinking that Machiavelli may have adopted the kind of ethical individualism that she ascribes to him. The chastened book that would have resulted from a more transparent method of reading would have been less ambitious (i.e., more constrained and limited -- and consistent with Machiavelli's virtue, as Benner understands it), to be sure, but nonetheless compelling and interesting. As it stands, Machiavelli's Ethics overreaches in far too many directions.

Reviewed by Robert Fiengo, City University of New York


 

The essays in this book, Kinds, Things, and Stuff, derive from a conference that addressed the cognitive issues raised by 'genericity' and the 'mass-count' distinction. These terms, as commonly deployed, have labile applications: they might refer to things-in-the-world, to our conceptions of things-in-the-world, or to the linguistic expressions we use to refer to things-in-the-world. Hence they are a common source of confusion, and it is a great virtue of this volume that the papers it contains quite generally respect these distinctions. All of the papers are avowedly 'psychological' in their thrust: given that languages mark these distinctions formally, what can we infer about the conceptual distinctions, if such there be, that lie behind the formal distinctions? Indeed, how can the nature of human conceptualization be explored experimentally at all? Potentially, there is interplay between research on genericity and research on the mass-count distinction: one might hope that understanding the psychological underpinnings of the mass-count distinction would help us to appreciate how we conceptualize genericity and kinds. And what might understanding our appreciation of generic truth teach us about the distinction we make between stuff and individuals? Is the type-token distinction, fraught as it is, also part of the same mix? I think it is fair to say that these questions are not completely answered in the volume under review, but at least it must be said that similar issues arise in both of the chosen domains, and that understanding how to argue for the conceptual underpinnings of the one might easily transfer to our elucidation of the other. And the volume provides some strong hints along these lines. The editor of the volume, Francis Pelletier, provides insightful philosophical introductions to both topics; there are five papers on generics and three papers on the mass-count distinction. Let me take these in order.

Greg Carlson seeks to close the gap he perceives between formal semantics and psychology. Using the term 'concept' to refer to subjective properties of individual psyches, he considers what relation there might be between concepts, so defined, and the meanings of generic noun phrases. He makes use of the important observation that while bare plural generic noun phrases occur in unlimited complexity (e.g., 'unpainted kitchen appliances'), definite singular generic noun phrases (e.g., 'the elephant') are much more restricted: contrast 'the friendly elephant', which lacks generic force. From this observation he arrives at the thought that definite singular generic noun phrases denote a kind if and only if the common noun denotes a concept (as 'elephant' is taken to do, but 'friendly elephant', not being a common noun, is not taken to do). This leads into some valuable speculation about natural kinds.

Sandeep Prasada asks the question of how, given our limited experience, we acquire generic knowledge. He reports on experimental work, pursued in a number of papers, in which he and his coauthors have distinguished between the properties a thing might have because it is that kind of thing and other properties a thing might have not for that reason: the 'k-properties' and the 't-properties', respectively. This distinction helps to explain why subjects paraphrase 'Dogs are four-legged' as 'Dogs are four-legged by virtue of being dogs', but do not paraphrase 'Barns are red' as 'Barns are red by virtue of being barns', while accepting both that dogs are generally four-legged and that barns are generally red. On his view, our conceptual system represents ties between kinds and properties; one piece of this connection is expressed as the 'Aspect Hypothesis', according to which kinds are, with some disclaimers, sets of k-properties. This leads to a consideration of various kinds of kinds, and our conceptions of them.

Francis Pelletier reports on a series of experiments aimed at deciding whether bare-plural generic sentences such as 'Birds fly' have the 'same generic force or meaning' as 'Most birds fly' or 'Birds usually fly', and concludes that, in at least some experimental manipulations, the bare-plural formulation contains information different from that contained in the other two. The experiments involve subjects' intuitions concerning the sort of default reasoning considered in Lifschitz (1989), an example being:

Birds fly.

Tweety and Polly are birds.

Polly doesn't fly.

Therefore, Tweety flies.

Subjects apparently consider this argument more valid than one in which the first premise is replace by 'Most birds fly' or 'Birds usually fly', yet this does not settle the question whether a distinction Carlson has made between inductivist and rules-and-regularities approaches to genericity is vindicated. Nor does it settle the question whether bare plurals refer to kinds. Pelletier does well in laying these issues out.

James Hampton's paper appeals to a version of 'prototype theory' to explicate vagueness and the instability of semantic judgments. He has experiments showing that being close to the center of a category underwrites more stable judgments of similarity to a prototype. And he has another set of experiments exploring the 'modifier effect', one of the consequences of which is that 'Ravens are black' is judged to be more true than 'Feathered ravens are black', which in turn is judged to be more true than 'Jungle ravens are black'. These results, and others he mentions, are argued to derive from the fact that people represent concepts 'in terms of a cluster of attributes that are typically true of the conceptual category'. A prototype need not be a visual image; what appears to be crucial is that people represent the 'central tendencies of classes, not their boundaries'.

Susan Gelman provides a lucid description of the mysteries surrounding the child's acquisition of generics. We learn that, despite the challenges posed by the expression of genericity in English, children make use of form-class cues to identify generics by the age of two and a half, and that, by the age of four, they produce generics as frequently as adults. And it is not that children are merely imitating: children actively initiate generic conversations. These observations, and others that derive from experiments Gelman reports on, lead to the suggestion that 'children assume a conceptual distinction between generic and specific reference'. They 'identify as generic those utterances that are not somehow marked specifically'. Generic interpretation, Gelman suggests, arises by default. This view appears to deny the popular conception that children are incapable of abstract thought, and has non-trivial implications for the acquisition of vocabulary.

The three papers on the mass terms begin with an effort by Cliff Goddard. He reports on work by Anna Wierzbicka pursuing the Natural Semantic Metalanguage system of lexical semantic representation. This approach allows for seven different subclasses of concrete mass nouns, examples of the classes being 'cheese', 'wheat', 'dust', 'gravel', 'oats', 'coffee grounds', and 'noodles'. Among the considerations that lead to these distinctions is whether or not the referent has recognizable parts, and if so whether they are named, as in the case of 'grain of wheat', or not, as in the case of 'gravel', and whether the noun occurs in the plural (as 'oats' does, but not 'wheat'). There are many descriptive fine points here worthy of consideration.

Edward Wisniewski reports on a variety of experiments all tending toward the view that there is a systematic relationship between speakers' conceptualization of the things around them and the mass-count distinction. To select a few results, an experiment by Middleton et al. (2004) found that subjects were more likely to choose a count term to refer to the individuals of a novel aggregate if they had interacted with its members. Following a suggestion by Wierzbicka, it was found that when individuals in a collection are rather easily discriminated, it is rather more likely that count nouns will be deployed; mass nouns predominate when this is not so. And there are some very interesting comparisons between pluralia tantum nouns (e.g., 'soapsuds', 'remains', 'scissors', etc.) and collective terms and mass terms. The view that the distinction between mass and count terms tracks, if even roughly, the way speakers conceptualize the things to which they refer is given full voice in this valuable paper and supported by some straightforward experimentation.

The paper by Fei Xu investigates how the representation of sortal concepts develops in infancy and then argues against the traditional view that the words of infancy are fundamentally different from the words of adulthood. Research by Xu and Carey suggests that between the ages of ten and twelve months infants develop the capacity to use 'property or sortal information to establish a representation of two distinct objects'. Twelve-month-old infants have been shown to be able to use the 'presence of labels to determine how many object were in a box whose content was invisible to them'. It appears that infants expect count nouns to 'refer to sortals/kinds, and that these representations support induction to new instances'. Xu argues that early words 'refer to kinds, just like later words'.

A collection of essays dedicated to a particular topic succeeds in its task if the reader can read it and come out with a good idea of what the issues in that area amount to. A reader who is interested in genericity or in the mass-count distinction, who is interested also in how the experimental literature speaks to these concerns, will be well rewarded. And the reader who might specialize in psychology, or in philosophy of mind, who is curious how language-based experimentation can contribute to their interests, will also be rewarded. Thanks go to Francis Pelletier for putting these valuable essays together.

Raymond Geuss, Politics and the Imagination, Princeton UP, 2010, 198pp., $24.95 (pbk), ISBN 9780691142289.

Reviewed by Mathias Risse, Harvard University


 

As Raymond Geuss states in the introduction to his 2008 Philosophy and Real Politics (PP), his book "wishes to suggest the possibility that there might be a viable way of thinking about politics that is orthogonal to the mainstream of contemporary analytic political philosophy" (p 18). Politics and the Imagination (PI) is plausibly understood (though does not explicitly introduce itself) as a sequel to PP. PI is a wide-ranging collection of essays with which readers will come to terms more easily if they have some sense of how they fit in with Geuss' attempt to provide such a non-mainstream approach. Therefore I begin with a few recollections of, and comments on, that earlier discussion.

Geuss rejects a particular way of understanding the idea that "politics is applied ethics," a view he calls the "ethics-first" reading of that slogan, and that he thinks penetrates contemporary political philosophy in pernicious ways. According to the ethics-first view, there is an independent discipline called "Ethics" that arrives at prescriptions concerning human activities independently of empirical investigations of concrete and historically embedded human endeavors. This discipline tends to formulate relatively few basic and rather abstract principles meant to provide systematic guidance for human behavior and that, in principle, apply to all contexts of human interaction. Often this view also presupposes some kind of individualism and gives considerable weight to basic moral intuitions. Geuss considers Rawls, Nozick, and Habermas defenders of this view, and attacks them for it.

The view Geuss champions also adopts the idea that "politics is applied ethics," but interprets it rather differently. Far from being a value-free enterprise, politics is populated by actors who pursue their respective conceptions of the good and think what they are doing is permissible, no matter how inconsistent or unreflective they are in their attitudes. Yet there is no independent subject called "Ethics" that can generate insights that then only need to be applied to the study of politics. Instead, value judgments of, or about, political actors always occur in particular contexts that we must understand before their historical background. This background must not merely inform value judgments, but a full understanding of this background renders abstract, non-context-specific ethical inquiries at best superfluous. At worst (and not unrealistically, as Geuss thinks, for instance with regard to Rawls) such inquiry leads to gross misconceptions of reality and thus, as the case may be, also to misguided interventions in it. Presumably as a consequence of this attitude towards what should be considered appropriate academic inquiry into human action, Geuss' Cambridge website

recommends that prospective post-graduate students in his areas of interest consider applying to the interdisciplinary M. Phil. in Intellectual History and Political Thought, administered by the Faculty of History, rather than to the M. Phil. of the Faculty of Philosophy.[1]

Geuss advocates what he calls realist political philosophy. The study of politics is a study of action, which is always historically situated action. Beliefs and ideals (according to Geuss a central preoccupation of post-Socratic philosophers) do matter, but only to the extent that they motivate people, not for some independent philosophical value they may have. Geuss obtains a good deal of his own philosophical inspiration from the pre-Habermasian Frankfurt School, especially Adorno, but also from Nietzsche. (Like Nietzsche's, Geuss' writings help themselves to frequent references to antiquity.) In the spirit of Critical Theory -- which Geuss elucidated very well in his first book, The Idea of a Critical Theory: Habermas and the Frankfurt School -- ideals must never be taken at face value: what people think about why they endorse ideals and about what their effects are may be totally wrong. Ideals -- like, say, social orders or academic disciplines -- have a way of inculcating illusions about their own character. (As far as academic disciplines are concerned, and as readers of Geuss' 2005 Outside Ethics may recall, he thinks that it is especially those who see themselves in the Rawlsian camp who are so deluded.) The study of politics, as a study of human action, is the study of power relations, and the adoption of belief systems cannot be detached from power relations. Politics itself is understood on the model of an art or a craft that requires particular skills (to make good judgments about what will happen, or to act at the right moment) that cannot be fully codified and thus neither systematically taught nor learned.

One must wonder about the contrast that Geuss draws between the "ethics-first" view (and the correspondingly low esteem in which he holds much philosophical work) and his own realist approach. It is worth recording these doubts because, again, the pieces in PI continue in the spirit of PP. Ethics, I take it, is concerned with offering systematic normative theories, theories about what it means to make judgments in terms of "right," "wrong," "good," "evil," etc. Thinking about what support systematic accounts of such terms have is independently worthwhile, so that we can come to an informed understanding of our evaluative practices. But such reflection does not immediately bear on what people actually do, and why they do it, and is consistent with lots of views about human motivation. Geuss is right that philosophers, like academics in other disciplines, tend to adopt ways of looking at the world that are highly partial ("To a man with a hammer everything looks like a nail," Mark Twain is reputed to have said), often overestimate the reach and relative importance of philosophical questions, and therefore inevitably neglect much about human interaction that deserves serious inquiry. So Geuss is right that those of us who work on normative questions are well-advised to adopt, well, a "critical" attitude towards what we are doing, and how it shapes our perception of what matters.

But none of this means -- and this manner of continuing is decidedly not meant to set aside the point just made, but merely to put it in perspective -- that there is something wrong with what Geuss calls ethics-first view as such, rather than with attitudes towards its reach and importance. The ethics-first view can adopt many of the lessons he teaches, unless Geuss means to deny the sheer validity of any universally applicable normative thought. Perhaps that indeed is what he means to do, but he himself acknowledges the possibility of normative thought per se. Once he does so (for instance, once judgments are classified as right, wrong, appropriate, inappropriate, etc.), we must ask what makes them so, and what makes them so in some situations but not in others, which, I take it, drives us to some version of universally applicable normative thought. In any event, it drives us a good deal beyond analyses of specific historical scenarios although such ethical inquiry is not always (maybe is only rarely) what is of greatest interest in reflection on such scenarios. The challenge becomes to identify the most sensible forms of such thought, which may well not be the Kantian approach that Geuss loathes. These themes are also explored in Thomas Hurka's review of PP in NDPR (2009.01.19).

Keeping these preliminary comments in mind, let us approach Politics and the Imagination. PI consists of twelve essays "that deal with several issues concerning the nature of the imagination and its role in politics" (p ix). It takes time to get used to this way of thinking, but, indeed, on Geuss' approach as sketched above, questions about ideals (such as normative theories) arise as questions about the imagination, as questions of how people have found guidance for their actions. Geuss begins by distinguishing two major ways in which exercises of the imagination have provided guidance: the view that justice ultimately will be done because history is bound to work out that way, and the view that fate is unrestrictedly malleable regardless of precedents. One can now ask about these particular (and rather different) forms of the use of imagination: how they relate to each other, or how they provide guidance in politics, or why they were attractive to particular agents and how they mattered to their choices. A natural way of thinking about the tasks of Critical Theory indeed is as a discipline that explores the conditions that make certain exercises of the imagination possible or likely, and assesses what it takes to distance oneself from one's own current imagination to determine if alternatives are available.

The unity created by this theme ("the nature of the imagination and its role in politics") is not tight. For some essays it is hard to see how they fit in with it at all. What I said above should explain how this collection continues Geuss' earlier work (and I think it captures how he himself sees this connection), but these essays have been published independently and reflect Geuss' amazingly broad range of interests. In addition to several essays that lay out his understanding of political philosophy and his views on geopolitical questions, we find essays on Celan, Heidegger, Rorty, Kant, Don Quixote, Wagner, the future role of museums, and the future possibility of critical inquiry. The rather cryptic introduction is not as helpful as one would have hoped to give guidance to the reader. Some of these essays I am not competent to engage with. Some I find hard to digest since they read like several sub-themes tied together that are interesting to ponder on their own and indeed are also "somehow" connected, but that leave at least this reader puzzled as to their overall purpose, even after repeated reading. But Geuss, in any event, presents a wealth of material and thinks his questions through in intriguing and often unexpected ways that make an engagement with his ideas worth the effort. So in light of these parameters, I will here discuss only a few of his essays.

The first essay, "Political Judgment in Its Historical Context," takes as its starting point a conversation between a former British ambassador to the US and several neo-conservative members of the administration of George W. Bush, a conversation recorded in the ambassador's memoirs. Geuss uses this conversation to illustrate the program of a realist political philosophy I sketched above. The kind of political philosophy ("ethics-first") that Geuss rejects is committed to a particular (post-Socratic) view of political judgment -- namely, political judgments are opinions that can be investigated by appeal to rational standards, in isolation from other judgments, and independently of the identity of the speakers; to the extent that these judgments are ethical in nature, they trump all other considerations bearing on what the agent should do. Geuss suggests that, for the purposes of finding "a fundamental concept the analysis of which would allow one to decipher a whole area of human experience" (p 5), one should not, as many philosophers have done, focus on the conception of belief or option, but on action. Politics is interaction among groups with differential power, and verbal interactions should be analyzed in terms of that model. The conversation between the British ambassador and the neo-cons illustrates the point: pronouncements about the political possibilities of the British government (which were the subject of that conversation) are not academic assessments, but convey information about the attitudes of the American government and exert pressure on the British government to act in certain ways.

Politics -- and this, I believe, indeed is the main point of this essay -- must not be understood as a quasi-academic discussion about a domain that by itself is not influenced by the way the discussion proceeds or ends. Such a view of politics does not do justice to the phenomena. Once that lesson is digested, one also sees politics as a particular context of human interaction in which a distinctively political ability can flourish and must be recognized as such: the ability "of practical imagination, inventiveness, or creativity, of coming up with new possibilities, or seeing new possibilities or constructiveness, which is very important in politics" (p 14). Geuss means to make a statement about the distinctive nature of the political domain. Appropriate moral judgments about particular exercises of this ability are a separate matter. An example he gives of a striking exercise of this ability is the attacks of September 11, a set of political actions that sent a powerful signal (without, as Geuss stresses, "saying a word") that got the opponents (the American government) to do precisely what quite plausibly had been intended by the attackers all along.

This first essay nicely illustrates the kind of realist political philosophy that Geuss thinks is appropriate and that I sketched above. But for that reason it also returns us to the points of resistance articulated above. It is true that one can watch any political debate, or even any interview with a politician, from various standpoints. One can think about it as verbal exchange and ponder whether the reply really addresses the point made by the opponent earlier, or whether the answer actually responds to the question the interviewer asked. Or one can think about the strategic political behavior displayed in the interaction: What points come across? What aspects of the politician's personality transpire, and are meant to transpire? The same is true, mutatis mutandis, of interactions that are not immediately watched by a larger audience. Much of this will be lost if one merely thinks about such interaction as an exchange of beliefs, and thus construes them on the model of quasi-academic discussions. About all this, I think one can only agree with Geuss. But none of this undermines the actual validity of academic discussion: none of this implies that one should not also think about the cognitive value of statements made in relevant discussions. So while Geuss' first essay illustrates what he means by realist political philosophy, it does not give us a reason to abandon the ethics-first view, or even illustrate why we should do so.

Geuss' third essay, "Moralism and Realpolitik," starts by insisting that philosophers are on the wrong track understanding politics by assuming that agents seek to obtain self-knowledge and consistency. This way of approaching politics leads to wrong views of how morality can sensibly enter politics. (This essay, I should say, is one of those that I find difficult to comprehend. I am here recording what I have made of it.) One way in which morality enters politics is through "moralism":

the view that the distinction between good and evil is clear and easy to discern to all men of good will . . . The genuinely admirable moral agent sees the salient features of a situation quickly and immediately, faces up to the situation resolutely, and acts decisively to implement his intuitions (p 32).

But moralism is problematic, among other things, because it leads agents to construe conflicts of interests as matters of principles, and because its endorsement unduly neglects the role of reflection in politics, minimally considerations of consistency. But once this kind of resistance to moralism is in sight, we must ask precisely why consistency matters to action. Crucially for Geuss, again, the central piece in making sense of politics is actions, not propositions. Actions can conflict, but not contradict each other. As the fit between propositions and actions is inherently loose, actions cannot immediately come up for an evaluation in terms of consistency. The complexity of actions and motivations makes it difficult to think of them in terms of the consistency of propositions. As Geuss says:

The more we move away from the glass realm of explicitly formulated propositions . . . [and] as we enter the realm of imagination, of human desires, ideals, emotions, hopes, projects, the more clearly we enter the world which most of us inhabit much of the time. Here things are left indeterminate, contradictory beliefs are entertained, trains of thought are left unfinished, conflicting emotions are tolerated (or even enjoyed) (p 38).

So plain moralism is unsatisfactory because it is too simple-minded, and moralism enriched with reflectiveness generates considerable theoretical difficulties. One response is to adopt a crude version of realism, that we should abandon moral considerations altogether and instead merely pursue our respective "material interest." But here too Geuss finds difficulties, in particular that material interest is an "accordion-like concept" (p 39). Following Max Weber (whom he considers the most important political philosopher of the 20th century), Geuss expresses much esteem for qādi justice, which largely gives up on generic advice and codification and instead expects experienced, wise judges to sort out the difficulties of particular cases. That is how he thinks value judgments should enter into politics. At this stage, this move should be unsurprising, because it captures Geuss' general outlook: realist political philosophy distinguished both from the ethics-first view and from crude forms of realism that deny the point of normative inquiry beyond advocating to act on one's material interest. Somewhat abruptly, towards the end of the essay, two additional thoughts enter whose connection with the rest of the train of thought Geuss does not explain well. To begin with, after the discussion of qādi justice Geuss articulates a view on genuinely significant political action. Like qādi justice, such action goes beyond codified rules. But it also goes much beyond qādi justice by creating an entirely new situation not even loosely connected to past conditions. (Geuss' example here again could be the September 11 attacks, though he does not say so.) He also points out, in an existentialist manner -- and I presume that this refers both to qādi justice and to genuinely political action -- that political decision making involves deciding not merely what kind of people we want to be ourselves, but what kind of a social world we would like to create and leave for the next generation.

Apologies to Raymond Geuss if I have been unable to put together the train of thought accurately. Geuss' admiration for qādi justice returns us to a general concern about his approach that I articulated above. Surely one should be able to ask the qādi just what factors about the situation in question prompted him to decide the way he did. Surely one would hope that the judge spent some time thinking about the matter by way of considering the weight these factors respectively should have in his decision, presumably also by thinking about what weight they would have under different circumstances, or in fact did have in the past in other decisions. Surely one would hope that the qādi, when prompted, could articulate his reasoning, and could thereby make clear to those subject to his jurisdiction that like case will indeed be treated alike. Some of the reasoning will be generic and broad-ranging in scope (for instance, pointing out that distinctly cruel treatment of human beings for entertainment purposes is unacceptable); some might draw heavily on details of the case, for instance, by working out precisely what would count as courageous action under the circumstances, what an agent could have been expected to know, what somebody could be blamed for given the conditions, etc. Perhaps these complexities are of a sort that does not allow for rigid codification of norms that in the future other judges merely have to apply. After all, there is a reason why there are judges in the first place.

If what I have said is correct, then Geuss, despite the validity of his concerns about the difficulties in obtaining insights about actions from considerations of consistency of propositions, too readily dismisses the relevance of careful background deliberation for politics. Thus he also too readily dismisses the relevance of philosophy as a discipline that engages in background deliberation about politics in a "cool hour," to use Bishop Butler's famous phrase. That such background deliberation needs to be subject to self-critical inquiry and comes with dangers of its own if that is not done I have already conceded. And that point, indeed, is an important insight that Geuss contributes.

Essay 4, "On the Very Idea of a Metaphysics of Right," contains Geuss' take on Kantian ethics. Geuss characterizes the view that he rejects as follows: (a) There is such a thing as Reason as an autonomous faculty that operates centrally with rules and principles, such as the principle of non-contradiction, and the results of the operation of which have the epistemic qualities of categoricity, aprioricity, universality, etc. (b) Reason has some powers of determining rules, and some motivational force for all human thought and action. (c) Because of a metaphysical connection between Reason and freedom, the enforcement of the rules that have their origin in Reason does not have the property of being truly coercive. (d) There is such a thing as (Kantian) Right, which provides for a set of rules that societies should be following even if they are not. Geuss articulates various objections to this view; the one that takes up most room in his discussion draws on the late Wittgenstein's reflections on rule-following. The point is that we have no way of knowing if we actually are following the rules that such a Kantian view would generate. The Kantian view generates no criterion to verify whether we are indeed following Reason-based rules. By way of contrast, Geuss' own realist approach can provide such a criterion quite readily, utilizing its emphasis on power: "the Athenians said so" might be such a criterion. Geuss offers additional objections: that Kant makes a mistake assuming that the operations of reason should be seen as a kind of legislation; that reason has the kind of authority over life Kant thought it did; and that a sufficiently broad and hence appropriate understanding of freedom cannot support the link between the conception of right and the conception of freedom that Kant supports because there is no inherent connection between freedom and rule-governing behavior.

Much of what Geuss says about Kant strikes me as plausible. In fact, his essay brings together a range of worries about Kant's project that many in the profession share. But in conjunction with my reactions to Essays 1 and 2 and the general worries about his project that I articulated earlier, my sense of Essay 4 is that it makes clear that Kant indeed is the most plausible target of Geuss' objections, in particular the specific conception of Reason and its role in human life that is distinctively Kantian. But one can object to that without throwing out as much philosophy as Geuss is inclined to do.

Let me proceed to Essay 7, "On Museums." This is the essay that I find is most straightforwardly written. One may wonder at first why this essay is included in a collection entitled Politics and the Imagination. But after all, the past engages our imagination and is a source of ideas for how to go about shaping the future. Museum visits presumably do not take up a considerable share of most people's time, but nonetheless it would be hard to imagine our lives entirely without museums and the kind of connection they provide to the past (at least for most people likely ever to read this review). Museums also compete for public funds. So the question of just what sort of exposure to the past, and what sort of stimulation for our experience museums create, does matter, and we can see how a discussion of museums fits in here. "Museums" are collections of artifacts intended for public display. Why should there be museums at all? One way of supporting the existence of museums is by appealing to their public usefulness. But how precisely would museums be useful? One way in which they might is by providing "edifying" knowledge, knowledge that could be moral or felicific. The former makes people better in their dealings with others, whereas the latter makes them better at improving their own lives. But is there such a thing as edifying knowledge? Even if there is, could museums (or could art) convey such knowledge? Geuss points out that Hitler was the greatest art collector and museum builder in the 20th century.

Nonetheless, at least the Enlightenment (an age that greatly promoted museums as we know them) did think that there was such knowledge, and that museums could provide it. According to Geuss, the Enlightenment assumed that there was "a single final system of all knowledge and that the knowledge in question would be both factual and edifying" (p 109), and thus could be readily connected to the improvement of both individual lives and social mores. Following Foucault, Geuss distinguishes between the doctrines and the ethos of the Enlightenment. The doctrines Geuss does not find persuasive, but he does endorse the ethos. That ethos requires an ongoing openness to criticism and self-criticism, and to new experiences. He thinks it is hard to envisage a flourishing future for museums unless they are connected to that kind of ethos. Given Geuss' other views readers should at this stage not be surprised to find him argue in this way. One important implication is that museums should become less explicitly didactic than many of them nowadays are. They should shy away from coherence and order, and instead focus more on giving an account of themselves. That is, they should document how the particular objects on display have ended up in that location, and explain why we find a museum there to begin with, and perhaps also why that particular building has taken on the shape that it has. In this way, visitors can reflect on the power relations that stand behind the possibility of the current exhibitions. Thereby, according to Geuss, the ethos of the Enlightenment would be fostered.

Reading Geuss' article on museums reminded me of a discussion of the Ashmolean museum in Oxford that I read a while ago, and that is rather contrary in spirit to Geuss' account. This discussion is from a book about Oxford published before the Ashmolean's recent renovation, I should add. The author reports on what he makes out to be a rather general feeling of disappointment with the museum, and then goes on:

It is not that wonderful things are lacking in the university collection; there are plenty. But no help is given to the visitor to find them. The Ashmolean is at least thirty years behind the rest of Europe when it comes to interesting and educating museum visitors -- and in another century when compared to the United States -- it ought to be in a museum itself. Almost everything is wrong; the entrance lobby is just a vast open space without information panels or direction pointers; one is left to just wander and see what one can find. Naturally, ninety percept of visitors march straight ahead and find themselves amid unfamiliar Chinese and Korean ceramics -- beautiful certainly, and well-displayed, but not what one expects to be greeted with in an Oxford collection. From there things go downhill; the amount of information given in most rooms is woefully inadequate . . . Cases are often stuffed with a collection of dozens of similar objects without a sign anywhere saying 'Hey! Look at this. It's important, It's exciting!' (David Horan, Oxford: A Cultural and Literary Companion, New York: Interlink Publishing, 2000).

One thing that resonates strongly with me is the admiration for American exhibitions that the author articulates. My own first visit to the Smithsonian in DC, about 15 years ago, evoked in me a strong sense that, indeed, that is how museum exhibits should be presented. Coherent stories were told in informative ways, and just enough information was provided for a visitor to read a fair number of panels without being exhausted. European museums always somehow seemed to provide too much or too little. What was wonderful for me precisely was the existence of signposts saying something like "Hey! Look at this. It's important, It's exciting!," and then explaining in some more detail why that was supposed to be so. I agree with Geuss that it is important to learn about the history of particular collections. Some museums (or exhibitions) are more forthcoming about this than others. But this is primarily interesting as a way of putting in perspective a particular story that is told in terms of the artifacts that the viewer sees on display. I presume the author of the excerpt about the Ashmolean would agree that this sort of self-documentation would not have solved the problems he identified about the pre-renovation Ashmolean. What we want, I think, is an interesting story told about, and in terms of, these artifacts, a story that then itself can be interrogated in terms of the story behind the presence of these artifacts in that particular location. Why would anybody want to go to a museum primarily to think about the story of the institution and its acquisition practices if there is no interesting story that can be told in terms of these artifacts? Or to put the point differently, a substantive story needs to be told in the first place that critical inquiry can then put in perspective.

The last essay I would like to discuss is Essay 12 (which is also the last essay in this collection), "On Bourgeois Philosophy and the Concept of Criticism," one of the five essays Geuss says "deal with some of the various ways in which imaginative distance finds expression internationally in cultural artifacts" (p xii). This is one of those sentences that I think make the introduction rather cryptic and badly in need of expansion. I am not sure how each of these five essays (Essay 12 being the only one among them that I discuss) meets the description Geuss gives. But in any event, the subject matter of Essay 12 is the future of Criticism, presumably with a capital letter because it is "Criticism" as in "Critical Theory." It is a reflection on the kind of philosophical approach that Geuss favors and its intellectual future. That is, Geuss ends his collection with self-reflection. Geuss begins this essay quoting some comments of Wittgenstein's about Frank Ramsey, whom Wittgenstein called a "bourgeois thinker." Geuss takes this to mean that Ramsey is being characterized as a philosopher who is not at all interested in radical criticism, especially in the sense that he does not investigate whether a political order of a fundamentally different sort is possible. Instead, Ramsey sets about to discover the order that existing political structures do exhibit.

But there is more to this notion. Bourgeois philosophy as Geuss understands it is a complex phenomenon that, in one version or another, characterizes many well-known thinkers. Geuss offers the following conditions to characterize bourgeois philosophy: (1) the world as we encounter it really is in order; (2) I can thus "make sense" of what I encounter in the world; (3) I can make sense of the world by using clear forms of surveyable knowledge that will be instrumentally useful and be capable of being justified; (4) I ought to embrace the world warmly. This indeed is a complex set of thoughts, and according to Geuss different thinkers have embraced or emphasized different bits of it, including Leibniz, Descartes, Hegel, the utilitarians, the pragmatists, and contemporary analytical philosophers. By way of illustrating bourgeois optimism, and how it retains its power in the 20th century and beyond, Geuss draws attention to Jonathan Lear and (again) Frank Ramsey. In Love and Its Place in Nature, Lear, according to Geuss, argues that, to the extent that somebody has developed into a mature, thinking person at all, this shows that her environment is good enough to allow for this process to take place. So anybody who succeeded at becoming that kind of person has good reason to be optimistic about her surroundings. In his collection of essays entitled Foundation of Mathematics, Ramsey argues that there is no particular emotional reaction to the world that is per se most appropriate. In light of that, there is nothing irrational about the adoption of an optimistic attitude towards the world because it is better for all my own activities to have a set of feelings towards the world that are positive rather than negative. Geuss rejects both views. We may get to the point of feeling good about the world in the way Lear explains, but may have no reason to think that it will also continue to be good. And Ramsey's approach holds for the world considered as the object of astronomy. But unlike the world of astronomy, it could be true of the world regarded as a social and political construct that my taking a positive attitude towards it implicates me in grave evil.

In an interesting (Nietzschean!) twist Geuss points out that Critical philosophy owes its existence to bourgeois philosophy. The existence of bourgeois philosophy itself presupposes particular societal arrangements in which philosophical thought is encouraged, and to some extent taken seriously. Bourgeois philosophy starts with the assumption that the world is fundamentally in order, but that does not mean that there cannot be local problems of all sorts, as for instance Hegel thought the Prussian state needed (comparatively) local reforms such as a constitution and universal trial by jury. In fact, this sort of gradual change is necessary for the perseverance of the bourgeois order, and clamoring for it is necessary for the continuation of bourgeois philosophy. Critical philosophy takes bourgeois philosophy as its starting point, and bourgeois philosophy must be able to persist for Critical philosophy to be applicable. But Geuss thinks that the whole bourgeois world is bound to collapse sooner rather than later (see also Essay 2, "The Politics of Managing Decline"), because of environmental and population problems and because of geopolitical shifts with considerable conflict potential. The collapse of the bourgeois world triggers the demise of bourgeois philosophy, which in turn triggers the demise of Critical philosophy. Geuss ends the book on a rather somber note.

And indeed, in the long run, as one might say in the words of yet another Cambridge man, we are all dead, and ditto for our philosophies. Unlike Geuss, Nietzsche, from whom he takes so much inspiration, was an optimist with regard to the questions that preoccupied him. He did think that we could overcome guilt, and he did think that we would eventually come to terms with the consequences of the "death of God." There is not enough room here to offer much substantive argument on these large issues, but personally I find it hard to share Geuss' gloomy-all-too-gloomy outlook. Perhaps that means I am firmly in the camp of the bourgeois optimists (given that I am certainly one who enjoys a good story being told about artifacts in a museum), but as far as the future of humanity is concerned, I think much remains open to us as long as sunlight continues to get to the earth to provide energy and as long as human intelligence continues to be connected to its accomplishments to date. Yes, technology has taken us where we are, but technology may also allow us to muddle through, at least to an extent required for the preservation of a bourgeois world with its bourgeois philosophy and its corresponding Critical philosophy. The jury is decidedly still out on this point. If the response to this move indeed is a charge of bourgeois optimism, a reply one might launch with equal plausibility (and this is a reply one might also launch with regard, say, to Geuss' strong criticism, in Outside Ethics, of Rawls and his assessment of the Rawls reception in the Western world in recent decades) is that the "critical," self-reflective part of Critical philosophy should also be applied to itself.

But this comment also puts me in a position to finish this review on a positive note. Raymond Geuss is an important contributor to contemporary political philosophy, not merely because of his particular way of continuing the tradition of Critical Theory, and not merely because of the sheer range of topics that he addresses with a mixture of intriguing analysis and unusual erudition, but also because he brings to bear the resources of Critical Theory on more mainstream political philosophy. In all these ways, he provides invaluable services to the profession.
