Medical student shows are a prominent feature of medical student life around the world. Following a traditional vaudeville format of skits and songs, the shows are notorious for their exuberance, bawdiness, and lack of political correctness. Despite their widespread prevalence and sometimes hostile reactions, there has been no previous study of these shows. Based on research of scripts, programs, reviews, and oral history, this article explores their history and content and argues that, far from being irrelevant frivolities, these shows serve (...) several important functions. These include the fostering of communal spirit, the development of skills in teamwork, and the collective ventilation of emotional reactions to the process of becoming a doctor. They are one offshoot of the ancient and important tradition of misrule in Western society. (shrink)

Human rights have become one of the most important moral concepts in global political life over the last 60 years. Charles Beitz, one of the world's leading philosophers, offers a compelling new examination of the idea of a human right.

Charles Beitz rejects two highly influential conceptions of international theory as empirically inaccurate and theoretically misleading. In one, international relations is a Hobbesian state of nature in which moral judgments are entirely inappropriate, and in the other, states are analogous to persons in domestic society in having rights of autonomy that insulate them from external moral assessment and political interference. Beitz postulates that a theory of international politics should include a revised principle of state autonomy based on the justice (...) of a state's domestic institutions, and a principle of international distributive justice to establish a fair division of resources and wealth among persons situated in diverse national societies.

In the present work, I constructively engage the thought of the American pragmatist John Dewey and the Zen Buddhist Dōmgen on moral cultivation. I argue that Dewey presents a useful notion of moral development and growth with a focus on attentiveness to one's situation, but I also note that he leaves out extended analysis of how one is to foster such an orientation. Turning to the writings of Dōmgen, I argue that Deweyan moral theory can be supplemented by the (...) methods that Zen Buddhism prescribes to bring attentiveness back to one's experience of activity. This analysis is placed in the context of my overall project of orientational meliorism, or the alteration of one's orientation toward self, world, and activity with the goal of improving the quality of one's future experience.

We present a probabilistic extension to active path analyses of token causation (Halpern & Pearl 2001, forthcoming; Hitchcock 2001). The extension uses the generalized notion of intervention presented in (Korb et al. 2004): we allow an intervention to set any probability distribution over the intervention variables, not just a single value. The resulting account can handle a wide range of examples. We do not claim the account is complete --- only that it fills an obvious gap in previous active-path approaches. (...) It still succumbs to recent counterexamples by Hiddleston (2005), because it does not explicitly consider causal processes. We claim three benefits: a detailed comparison of three active-path approaches, a probabilistic extension for each, and an algorithmic formulation. (shrink)

_A concise history of “just price,” from Aristotle to the present day_ The question of what constitutes a fair price has been at the center of market interactions since the time of Aristotle. Should a seller sell to the highest bidder, or is there some other standard, such as a morally defined price, to be applied? Charles R. Geisst traces the ways that philosophers, religious leaders, and economists have sought to answer that question, from antiquity through the modern era. (...) Aristotle’s thinking on usury influenced the idea of pricing well into the Renaissance. In his view, money was barren and should not be used to beget more money. As trade became more extensive, the strictures placed on pricing by Aristotelian thinking began to fall away, replaced by Roman and common-law conceptions of value and interest. Geisst’s book follows the evolution of that thought—influenced along the way by figures such as Copernicus, Fibonacci, Adam Smith, Marx, Cassel, and Keynes—and charts parallel developments in European and Islamic notions of fair pricing. Today, pricing is seen as an economic inevitability, dictated by the laws of supply and demand. But this has not always been the case. As Geisst argues, the idea of a just price was once a moral concept, long before it was an economic one. (shrink)

The collapse of historicism was not merely the demise of an academic tradition but signified a shift in the understanding of hermeneutics and metaphysics. Whereas earlier books have explored the rise and dominance of historicism within academic history, this is the first to trace its collapse and to show how it was shaped by larger philosophical and scientific concerns. Charles R. Bambach's lucid account of the demise of historicism within the context of German metaphysics provides a rich new perspective (...) on the development of the young Heidegger's concept of "historicity" and on the origins of postmodern thought. Bambach reconstructs the methodological debates arising from a pervasive sense of crisis among German philosophers in the late nineteenth century. He details the divergent attempts by the Neo-Kantians, Nietzsche, and Dilthey to overcome the limitations of historical relativism. Heidegger's view of "historicity," Bambach shows, radically transforms the problematic of historicism into a discourse concerning the crisis of philosophical modernity. (shrink)

Professor Flathman's main aim in this interesting paper is to set forth what we might call the “moderation thesis.” It holds that there may be occasions when the best thing to do, all things considered, is to violate a right – at least if the violation takes the form of what Flathman calls “civil encroachment” or “civil non-enforcement.” Moreover, it would be desirable, in a society whose practices include rights, for this belief to be generally accepted, so that those who (...) engaged with good reason in “civil encroachment” would receive the sympathetic support of the community. Let me begin by trying to explain the source of the problem to which this thesis is a response. As Flathman notes, rights have a discretionary character: if I have a right to do or to have something, it is up to me whether to do it or to have it. Having a right, I am entitled to make a choice. Since we cannot say, in advance, what choice I will make, we cannot say, in advance, what will be the state of the world after I make it. But since it seems plain that some states of the world are more desirable than others, it will always be possible that the consequences of my choice will be worse, on the whole, than the consequences of some other choice that I might have made but did not. To moderate rights is apparently to act in ways that redress or compensate for the undesirable results of their exercise. (shrink)

Patrick Stokes has argued that although many conspiracy theories are true, we should reject the policy of particularism (that is, the policy of investigating conspiracy theories if they are plausible and believing them if that is what the evidence suggests) and should instead adopt a policy of principled skepticism, subjecting conspiracy theories – or at least the kinds of theories that are generally derided as such – to much higher epistemic standards than their non-conspiratorial rivals, and believing them only if (...) they are proven up to the hilt. The reason is that although some conspiracy theories are true (or otherwise epistemically kosher) there is a widespread practice of conspiracy theorizing which leads to the social acceptance of conspiracy theories which (much like Lord Byron) are mad, bad and dangerous to ‘know’, leading to radically false beliefs about the natural and political worlds (for instance to Trump’s claim that Global Warming is a ‘Chinese Hoax’). Thus Stokes is a defender of the epistemic status quo in which the punditocracy routinely dismisses and sneers at ‘conspiracy theories’, simply because they are conspiracy theories, whilst admitting sotto voce that once in a blue moon there are some conspiracy theories that are true. It is just the he would prefer the epistemic policy of the punditocracy to be the policy of the populace at large. Stokes seems to be suggesting that although particularism looks like a sensible epistemic policy (and might indeed be the correct policy in an ideal world), if it were put into practice at the level of public debate it would give a specious air of plausibility to many false and dangerous conspiracy theories with pernicious social effects. I reply that the actual moral costs of conspiracy ‘skepticism’ (as it is currently practiced) exceed the likely costs of particularism, especially if it is informed by some sensible heuristics, ruling out some conspiracy theories as crazy and ruling in others as relatively sane. For the conspiracy ‘skepticism’ as currently practiced is highly selective, pouring scorn and contempt on conspiracy theories which threaten current elites whilst giving the conspiratorial concoctions of those elites something close to a free pass.

Nihilism, Nietzsche and the Doppelganger Problem Was Nietzsche a nihilist? Yes, because, like J. L. Mackie, he was an error-theorist about morality, including the elitist morality to which he himself subscribed. But he was variously a diagnostician, an opponent and a survivor of certain other kinds of nihilism. Schacht argues that Nietzsche cannot have been an error theorist, since meta-ethical nihilism is inconsistent with the moral commitment that Nietzsche displayed. Schacht’s exegetical argument parallels the substantive argument (advocated in recent years (...) by Wright and Blackburn) that Mackie’s error theory can’t be true because if it were, we would have to give up morality or give up moralizing. I answer this argument with a little bit of help from Nietzsche. I then pose a problem, the Doppelganger Problem, for the meta-ethical nihilism that I attribute to Mackie and Nietzsche. (If A is a moral proposition then not-A is a moral proposition: hence not all moral propositions can be false.) I solve the problem by reformulating the error theory and also deal with a variant of the problem, the Reinforced Doppelganger, glancing at a famous paper of Ronald Dworkin’s. Thus, whatever its demerits, the error theory, is not self-refuting, nor does it require us to give up morality. (shrink)

Throughout his philosophical career, Eric Voegelin had much to say about literature in both his published work and his private letters. Many of his most trenchant comments regarding the analysis of literature appear in his correspondence with critic Robert Heilman, and, through his familiarity with that exchange, Charles Embry has gained extraordinary insight into Voegelin’s literary views. _The Philosopher and the Storyteller_ is the first book-length study of the literary dimensions of Voegelin’s philosophy—and the first to use his philosophy (...) to read specific novels. Bringing to bear a thorough familiarity with both Voegelin and great literature, Embry shows that novels—like myths, philosophy, and religious texts—participate in the human search for the truth of existence, and that reading literature within a Voegelinian framework exposes the existential and philosophical dimensions of those works. Embry focuses on two key elements of Voegelin’s philosophy as important for reading literature: metaxy, the in-between of human consciousness, and metalepsis, human participation in the community of being. He shows how Voegelin’s philosophy in general is rooted in literary-symbolic interpretation and, therefore, provides a foundation for the interpretation of literature. And finally he explores Voegelin’s insistence that the soundness of literary criticism lies in the consciousness of the reader. Embry then offers Voegelinian readings that vividly illustrate the principles of this approach. First he considers Graham Swift’s _Waterland_ as an example of the human search for meaning in the modern world, then he explores the deformation and recovery of reality in Heimito von Doderer’s long and complex novel _The Demons,_ and finally he examines how Flannery O’Connor’s _The Violent Bear It Away_ mythically expresses the flux of divine presence in what Voegelin calls the Time of the Tale. _The Philosopher and the Storyteller_ unites fiction and philosophy in the common quest to understand our nature, our world, and our cosmos. A groundbreaking exploration of the connection between Voegelin and twentieth-century literature, this book opens a new window on the philosopher’s thought and will motivate readers to study other novels in light of this approach.

We present a minimum message length (MML) framework for trajectory partitioning by point selection, and use it to automatically select the tolerance parameter ε for Douglas-Peucker partitioning, adapting to local trajectory complexity. By examining a range of ε for synthetic and real trajectories, it is easy to see that the best ε does vary by trajectory, and that the MML encoding makes sensible choices and is robust against Gaussian noise. We use it to explore the identification of micro-activities within a (...) longer trajectory. This MML metric is comparable to the TRACLUS metric – and shares the constraint of abstracting only by omission of points – but is a true lossless encoding. Such encoding has several theoretical advantages – particularly with very small segments (high frame rates) – but actual performance interacts strongly with the search algorithm. Both differ from unconstrained piecewise linear approximations, including other MML formulations. (shrink)

l. There is an antinomy in Hare's thought between Ought-Implies-Can and No-Indicatives-from-Imperatives. It cannot be resolved by drawing a distinction between implication and entailment. 2. Luther resolved this antinomy in the l6th century, but to understand his solution, we need to understand his problem. He thought the necessity of Divine foreknowledge removed contingency from human acts, thus making it impossible for sinners to do otherwise than sin. 3. Erasmus objected (on behalf of Free Will) that this violates Ought-Implies-Can which he (...) supported with Hare-style ordinary language arguments. 4. Luther a) pointed out the antinomy and b) resolved it by undermining the prescriptivist arguments for Ought-Implies-Can. 5. We can reinforce Luther's argument with an example due to David Lewis. 6. Whatever its merits as a moral principle, Ought-Implies-Can is not a logical truth and should not be included in deontic logics. Most deontic logics, and maybe the discipline itself, should therefore be abandoned. 7. Could it be that Ought-Conversationally-Implies-Can? Yes - in some contexts. But a) even if these contexts are central to the evolution of Ought, the implication is not built into the semantics of the word; b) nor is the parallel implication built into the semantics of orders; and c) in some cases Ought conversationally implies Can, only because Ought-Implies-Can is a background moral belief. d) Points a) and b) suggest a criticism of prescriptivism - that Oughts do not entail imperatives but that the relation is one of conversational implicature. 8. If Ought-Implies-Can is treated as a moral principle, Erasmus' argument for Free Will can be revived (given his Christian assumptions). But it does not 'prove' Pelagianism as Luther supposed. A semi-Pelagian alternative is available. (shrink)

Hebb's conception of instinctive behavior permits the conclusion that it is just not human nature to be instinctive: while the ant brain is built for instinctive behavior, the human brain is built for intelligent behavior. Since drives cannot be instincts, even when a human driver becomes driven, human motives are not instincts either. This understanding allows us to dismiss the determinism of the old instinctivism found in Freud's bio-psychological unconscious, and of the new instinctivism, exemplified by Wilson's sociobiology. The latter (...) entails an explanatory shift from instincts to genes, in which the deterministic character of instincts is carried over to genes. Since genes are not instincts this is a mistake.

Contrary to popular imagination, the division between those countries which allow freedom to preach the gospel and those which deny it is not the line between Marxist and non-Marxist states. Both left and right wing authoritarian regimes tolerate gospels that focus exclusively on individual religious concerns that are politically uncritical. This frees them from any criticism on religious grounds. There is another formulation of the gospel which is not reductionist and which asserts the Lordship of Christ over the entire universe (...) and all aspects of its life. Such a formulation is a serious threat to any totalitarian regime of whatever ideology. (shrink)

My first paper on the Is/Ought issue. The young Arthur Prior endorsed the Autonomy of Ethics, in the form of Hume’s No-Ought-From-Is (NOFI) but the later Prior developed a seemingly devastating counter-argument. I defend Prior's earlier logical thesis (albeit in a modified form) against his later self. However it is important to distinguish between three versions of the Autonomy of Ethics: Ontological, Semantic and Ontological. Ontological Autonomy is the thesis that moral judgments, to be true, must answer to a realm (...) of sui generis non-natural PROPERTIES. Semantic autonomy insists on a realm of sui generis non-natural PREDICATES which do not mean the same as any natural counterparts. Logical Autonomy maintains that moral conclusions cannot be derived from non-moral premises.-moral premises with the aid of logic alone. Logical Autonomy does not entail Semantic Autonomy and Semantic Autonomy does not entail Ontological Autonomy. But, given some plausible assumptions Ontological Autonomy entails Semantic Autonomy and given the conservativeness of logic – the idea that in a valid argument you don’t get out what you haven’t put in – Semantic Autonomy entails Logical Autonomy. So if Logical Autonomy is false – as Prior appears to prove – then Semantic and Ontological Autonomy would appear to be false too! I develop a version of Logical Autonomy (or NOFI) and vindicate it against Prior’s counterexamples, which are also counterexamples to the conservativeness of logic as traditionally conceived. The key concept here is an idea derived in part from Quine - that of INFERENCE-RELATIVE VACUITY. I prove that you cannot derive conclusions in which the moral terms appear non-vacuously from premises from which they are absent. But this is because you cannot derive conclusions in which ANY (non-logical) terms appear non-vacuously from premises from which they are absent Thus NOFI or Logical Autonomy comes out as an instance of the conservativeness of logic. This means that the reverse entailment that I have suggested turns out to be a mistake. The falsehood of Logical Autonomy would not entail either the falsehood Semantic Autonomy or the falsehood of Ontological Autonomy, since Semantic Autonomy only entails Logical Autonomy with the aid of the conservativeness of logic of which Logical Autonomy is simply an instance. Thus NOFI or Logical Autonomy is vindicated, but it turns out to be a less world-shattering thesis than some have supposed. It provides no support for either non-cognitivism or non-naturalism.

Proponents of the view that social structures are ontologically distinct from the people in whose actions they are immanent have assumed that structures can stand in causal relations to individual practices. Were causality to be no more than Humean concomitance correlations between structure and practices would be unproblematic. But two prominent advocates of the ontological account of structures, Bhaskar and Giddens, have also espoused a powers theory of causality. According to that theory causation is brought about by the activity of (...) particulars, in the social psychological case, individuals of some sort. Consistence would demand that structure be those individuals. But neither Giddens nor Bhaskar wish to reify structure to the extent that would fit it for a role as a powerful particular. If only human beings can be powerful particulars in these contexts, the only way that structures can be real must be as properties of conversational interactions. Human action is social just in so far as people direct themselves to engage well in joint activities with others. (shrink)

Paper presented to the Twenty-seventh Hume Society Conference, 26 July 2000, Williamsburg, Virginia. -/- At the time I thought there was a stronger link between Maclaurin and Hume, but in discussions at and after the meeting, decided Hume was not taking his mechanics out of Maclaurin’s Account. Although I still have found Maclaurin useful in interpreting Hume -- see Sapadin 1997 for a discussion of popular Newtonianism in Hume's day -- I suspect my draft suffers somewhat from ambivalence. There are (...) still similarities, and possible avenues of influence, arguing that Hume was not ignorant of the new mechanics, but it also becomes clear that he did not understand it: although he adopts the Newtonian measure of force, he misapplies it.

Philosophical attention to problems about global justice is flourishing in a way it has not in any time in memory. This paper considers some reasons for the rise of interest in the subject and reflects on some dilemmas about the meaning of the idea of the cosmopolitan in reasoning about social institutions, concentrating on the two principal dimensions of global justice, the economic and the political.

Contemporary ethical thought owes a great deal to David Hume whose work has inspired theories as diverse as non-cognitivism, error theory, quasi-realism, and instrumentalism about practical reason. This timely volume brings together an international range of distinguished scholars to discuss and dispute issues revolving around three closely related Humean themes which have recently come under close scrutiny. First is Hume's infamous claim that 'Reason is, and ought only to be, the slave of the passions'. Second, the Motivation Argument for the (...) view that 'The rules of morality...are not conclusions of our reason'. The third and final theme is that of virtue, re-examined here in the context of new interpretational debates concerning Hume's thought on moral motivation.

In his celebrated 'Good and Evil' (l956) Professor Geach argues as against the non-naturalists that ‘good’ is attributive and that the predicative 'good', as used by Moore, is senseless.. 'Good' when properly used is attributive. 'There is no such thing as being just good or bad, [that is, no predicative 'good'] there is only being a good or bad so and so'. On the other hand, Geach insists, as against non-cognitivists, that good-judgments are entirely 'descriptive'. By a consideration of what (...) it is to be an A, we can determine what it is to be a good A, even where the ‘A’ in question is ‘human being’. These battles are fought on behalf of naturalism, indeed, of an up-to-date Aristotelianism. Geach plans to 'pass' from the 'purely descriptive' man to good/bad man, and from human act to good/bad human act. I argue: (l) That the predicative 'good' does have a genuine sense and that it is a mistake to suppose that ‘good’ is a purely attributive adjective. This does not entail that the predicative good (as used by Moore) denotes a non-natural property, but his mistake, if any is metaphysical or ontological not conceptual. (2) That the attributive 'good' cannot be used to generate a naturalistic ethic. It is difficult to extract a set of biologically based requirements out of human nature that are a) reasonably specific; b) rationally binding or at least highly persuasive; and c) morally credible. -/- On the way I protest against Geach’s tendency to try to win arguments by affecting not to understand things. -/- My views to some extent anticipate those of Kraut in *Against Absolute Goodness*.

The description for this book, Political Equality: An Essay in Democratic Theory, will be forthcoming.

Global economic and political inequalities are in most respects greater today than they have been for decades. From one point of view inequality is a bad thing simply because it involves a deviation from equality, which is thought to have value for its own sake. But it is controversial whether this position can be defended, and if it can, whether the egalitarian ideal on which the defense may depend applies at the global level as in individual societies. Setting aside directly (...) egalitarian reasons for concern about global inequality, this paper explores several reasons for concern that derive from nonegalitarian values – primarily those associated with poverty and material deprivation, humiliation, the impact of inequality on the capacity for self‐control and self‐government, and the unfairness of political decision‐making procedures with large economic inequalities in the background.

Are conspiracy theorists epistemically vicious? That is the conventional wisdom. It has distinguished supporters, including Quassim Cassam, Cass Sunstein and Adrian Vermeule. For me, a trait is an epistemic virtue if leads to the discovery of salient truths and the avoidance of pernicious falsehoods, and an epistemic vice the contrary. As such epistemic virtues and vices are role‐relative, context‐relative and end‐relative. I argue that that it is not necessarily or even usually vicious to be a conspiracy theorist, even if we (...) restrict the conspiracies in question to conspiracies on the part of Western government agencies, the reason being that many such theories are now known to be true. Finally I contend that the policy suggested by some polemicists of systematic skepticism towards conspiracy theories would be intellectually suicidal and hence vicious. (shrink)

The investigation of probabilistic causality has been plagued by a variety of misconceptions and misunderstandings. One has been the thought that the aim of the probabilistic account of causality is the reduction of causal claims to probabilistic claims. Nancy Cartwright (1979) has clearly rebutted that idea. Another ill-conceived idea continues to haunt the debate, namely the idea that contextual unanimity can do the work of objective homogeneity. It cannot. We argue that only objective homogeneity in combination with a causal interpretation (...) of Bayesian networks can provide the desired criterion of probabilistic causality. (shrink)

Classifying species as ‘native’ or ‘alien’ carries prescriptive force in the valuation and management of ‘nature’. But the classification itself and its application are contested, raising philosophical and geographical questions about place, space, rights, identity and belonging. This paper discusses leading critiques of the native/alien paradigm, including its conceptual fluidity, dichotomous rigidity and ethical difficulties, as well as the incendiary charge of xenophobia. It argues that valorizing ‘native nature’ as inherently the ‘best nature’ is not only obsolete but impracticable in (...) the Anthropocene, and that the preeminence of biogeographic origins should be replaced with a pragmatic focus on species’ behavior.

This paper is a critique of coercive theories of meaning, that is, theories (or criteria) of meaning designed to do down ones opponents by representing their views as meaningless or unintelligible. Many philosophers from Hobbes through Berkeley and Hume to the pragmatists, the logical positivists and (above all) Wittgenstein have devised such theories and criteria in order to discredit their opponents. I argue 1) that such theories and criteria are morally obnoxious, a) because they smack of the totalitarian linguistic tactics (...) of the Party in Orwell’s 1984 and b) because they dehumanize the opposition by portraying them as mere spouters of gibberish; 2) that they are profoundly illiberal since if true, they would undermine Mill’s arguments for free speech; 3) that such theories are prone to self-contradiction, pragmatic and otherwise; 4) that they often turn against their creators including what they were meant to exclude and excluding what they were meant to include; 5) that such theories are susceptible to a modus tollens pioneered by Richard Price in his Review Concerning the Principle Questions of Morals(1758); and 6) that such theories are prima facie false since they fail to ‘predict’ the data that is it their business to explain (or, in the case of criteria, fail to capture the concept that they allegedly represent). The butcher’s bill is quite considerable: some of Hobbes, a fair bit of Locke, half of Berkeley, large chunks of Hume, Russell's Theory of Types, verificationism in its positivist and Dummettian variants, much of pragmatism and most of Wittgenstein - all these have to be sacrificed if we are to save our souls as philosophic liberals.

"The Moral Standing of States" is the title of an essay Michael Walzer wrote in response to four critics of the theory of nonintervention defended in "Just and Unjust Wars." It states a theme to which he has returned in subsequent work. Beitz offers four sets of comments.

The paper reconstructs Moore's Open Question Argument (OQA) and discusses its rise and fall. There are three basic objections to the OQA: Geach's point, that Moore presupposes that ?good? is a predicative adjective (whereas it is in fact attributive); Lewy's point, that it leads straight to the Paradox of Analysis; and Durrant's point that even if 'good' is not synonymous with any naturalistic predicate, goodness might be synthetically identical with a naturalistic property. As against Geach, I argue that 'good' has (...) both predicative and attributive uses and that in moral contexts it is difficult to give a naturalistic account of the attributive 'good'. To deal with Lewy, I reformulate the OQA. But the bulk of the paper is devoted to Durrant's objection. I argue that the post-Moorean programme of looking for synthetic identities between moral and naturalistic properties is either redundant or impossible. For it can be carried through only if 'good' expresses an empirical concept, in which case it is redundant since naturalism is true. But 'good' does not express an empirical concept (a point proved by the reformulated OQA). Hence synthetic naturalism is impossible. I discuss direct reference as a possible way out for the synthetic naturalist and conclude that it will not work. The OQA may be a bit battered but it works after a fashion. (shrink)

Information theory provides a quantitative conceptual framework for understanding the flow of information from the world into and through brains. It focuses our attention on the sets of possible messages a brain's anatomy and physiology enable it to receive. The meanings of the messages arise from the inferences licensed by the brain's processing of them. Different meanings arise at different levels because different representations of the input license different inferences.

Numbers are symbols manipulated in accord with the axioms of arithmetic. They sometimes represent discrete and continuous quantities, but they are often simply names. Brains, including insect brains, represent the rational numbers with a fixed-point data type, consisting of a significand and an exponent, thereby conveying both magnitude and precision.
