An account of the three rival conceptions of Western philosophy: "theoretical," "difference," and "practical." -/- Posted 29 January 2023.

An account of two sources of the "minimal global ethic," one interpretive and the other creative. Humour, more specifically slapstick, is the interpretive source, while "revelation" as present in both Rabbinic Judaism and Modernism is the creative source. The question of the ethic and conflict is then briefly discussed. This version, posted 22 January 2023, is a revised form of the chapter from the book published in 2009.

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)

Human rights have made mass murder and genocide more, rather than less, likely. -/- Posted 21 December 2022. A previous version of this paper appears as chapter 3 of my Patriotic Elaborations: Essays in Practical Philosophy (Montreal and Kingston: McGill-Queen’s University Press, 2009).

Despite his position as one of the first philosophers to write in the “post- Darwinian” world, the critique of Darwin by Friedrich Nietzsche is often ignored for a host of unsatisfactory reasons. I argue that Nietzsche’s critique of Darwin is important to the study of both Nietzsche’s and Darwin’s impact on philosophy. Further, I show that the central claims of Nietzsche’s critique have been broadly misunderstood. I then present a new reading of Nietzsche’s core criticism of Darwin. An important (...) part of Nietzsche’s response can best be understood as an aesthetic critique of Darwin, reacting to what he saw as Darwin having drained life of an essential component of objective aesthetic value. For Nietzsche, Darwin’s theory is false because it is too intellectual, because it searches for rules, regulations, and uniformity in a realm where none of these are to be found – and, moreover, where they should not be found. Such a reading goes furthest toward making Nietzsche’s criticism substantive and relevant. Finally, I attempt to relate this novel explanation of Nietzsche’s critique to topics in contemporary philosophy of biology, particularly work on the evolutionary explanation of culture. (shrink)

Grice and Strawson's 'In Defense of a Dogma is admired even by revisionist Quineans such as Putnam (1962) who should know better. The analytic/synthetic distinction they defend is distinct from that which Putnam successfully rehabilitates. Theirs is the post-positivist distinction bounding a grossly enlarged analytic. It is not, as they claim, the sanctified product of a long philosophic tradition, but the cast-off of a defunct philosophy - logical positivism. The fact that the distinction can be communally drawn does not (...) show that it is based on a real difference. Subcategories that can be grouped together by enumeration will do the trick. Quine's polemical tactic (against which Grice and Strawson protest) of questioning the intelligibility of the distinction is indeed objectionable, but his argument can be revived once it is realized that 'analytic' et al. are theoretic terms, and there is no extant theory to make sense of them. Grice and Strawson's paradigm of logical impossibility is, in fact, possible. Their attempt to define synonymy in Quinean terms is a failure, nor can they retain analyticity along with the Quinean thesis of universal revisability. The dogma, in short, is indefensible.

This includes a methodological meditation (in blank verse) on the history of philosophy as a contribution to philosophy (rather than as a contribution to history) plus a conspectus of the issues surrounding Hume, the Motivation Argument and the Slavery of Reason Thesis. However I am posting it here mainly because it contains a novel restatement of the Argument from Queerness. Big Thesis: the Slavery of Reason Thesis (via the Motivation Argument) provides no support for non-cognitivism or emotivism, but there is (...) a plausible version of the Slavery of Reason Thesis that provides some support for the Error Theory. As in other papers I stress the importance of DTADs, dispositions to acquire desires as well as desires conceived as propositional attitudes. (shrink)

Do you think the quotation in my title is reasonable or unreasonable? I find it unreasonable, but I know that many will not. Two people can react to the same idea, opinion, or data in opposite ways, and the reasons for this are often ideological. Ideology always has a political origin — in this case perhaps reflecting turf wars, career promotion, self-legitimation, the privileged status of science in post-industrial societies, and the need to say the right things in order (...) to get research funding. The very concept of ‘hard science’ is ideological, implying that one part of our experience is ‘objective’ (meaning that it confers authority on scientists) and the other part is ‘subjective’(meaning that the opinions of non-scientists are of little worth).What we call ‘objective’ is of course a mental model built on the basis of experiences which we call ‘subjective’. There are many possible ways of carving up experience, but none that leads to a useful or non-political distinction between ‘objective’ and ‘subjective’. (shrink)

The eminent French biologist and historian of biology, François Jacob, once notoriously declared “On n’interroge plus la vie dans les laboratoires”: laboratory research no longer inquires into the notion of ‘Life’. Nowadays, as David Hull puts it, “both scientists and philosophers take ontological reduction for granted… Organisms are ‘nothing but’ atoms, and that is that.” In the mid-twentieth century, from the immediate post-war period to the late 1960s, French philosophers of science such as Georges Canguilhem, Raymond Ruyer and Gilbert (...) Simondon returned to Jacob’s statement with an odd kind of pathos: they were determined to reverse course. Not by imposing a different kind of research program in laboratories, but by an unusual combination of historical and philosophical inquiry into the foundations of the life sciences (particularly medicine, physiology and the cluster of activities that were termed ‘biology’ in the early 1800s). Even in as straightforwardly scholarly a work as La formation du concept de réflexe aux XVIIe et XVIIIe siècles (1955), Canguilhem speaks oddly of “defending vitalist biology,” and declares that Life cannot be grasped by logic (or at least, “la vie déconcerte la logique”). Was all this historical and philosophical work merely a reassertion of ‘mysterian’, magical vitalism? In order to answer this question we need to achieve some perspective on Canguilhem’s ‘vitalism’, notably with respect to its philosophical influences such as Kurt Goldstein. (shrink)

A review, posted 11 September 2002, of Richard Vernon's book. A previous version was published in the Canadian Journal of Political Science 39, no. 4 (Dec. 2006): 975–76.

The great American philosopher, Charles Peirce, calls his pragmatism a continuation of Jesus' teaching, "Ye may know them by their fruit," and labels his cosmology a doctrine of "Christian Love." Nonetheless, I have found Peirce's understanding of Christianity to be surprisingly unpragmatic. Peirce's pragmatism itself displays an unpragmatic side and the tension between his pragmatic and unpragmatic tendencies reappears in his philosophic theology. I am not certain what a consistently pragmatic Christian theology would look like, but I know pragmatism (...) is the rule rather than the exception in rabbinic Judaism, that is the classical, post-Biblical Judaism of the Talmud. In this paper, therefore, I evaluate Peirce's pragmatism and his Christian theology from the perspective of the rabbis. (shrink)

By definition, “logic of postmodernism" would appear to be a contradiction in terms: philosophic post¬modernism emerged as a critique of attempts to found philosophy on some principle of reasoning and to found reasoning on some formal guidelines for how we ought to think. Nonetheless, there are two reasons why Charles Sanders Peirce (1839-1914) ought to be labeled the logician of postmodernism — the philosopher who, more than any other, etched out the normative guidelines for postmodern thinking. The first (...) reason is that Peirce attempted to accomplish the impossible, or at least the contradictory. He launched his philosophic career with a logical critique of "Cartesianism" — his label for the modernist attempt to found philosophy on some formal principles of reasoning. He then attempted to replace the principles of Cartesian reasoning with a set of anti-modernist principles that proved themselves to be as modernist as their contraries. The second reason for giving Peirce his label is that his failures to accomplish the impossible engendered in him something he was unable to achieve willfully: a habit of self-critical yet self-affirming thinking that was neither modernist nor anti-modernist but, rather, a disciplined variety of postmodern thinking. In his later years, Peirce began to sketch out the principles of philosophic postmodernism by describing features of his own emergent habit of thinking. This sketching comes close enough to what I would label a logic of postmodernism — where the method of logic is as postmodern as the thinking it describes. (shrink)

In Part 1, I contend (using Coriolanus as my mouthpiece) that Keeley and Clarke have failed to show that there is anything intellectually suspect about conspiracy theories per se. Conspiracy theorists need not commit the ‘fundamental attribution error’ there is no reason to suppose that all or most conspiracy theories constitute the cores of degenerating research programs, nor does situationism - a dubious doctrine in itself - lend any support to a systematic skepticism about conspiracy theories. In Part 2. I (...) argue (in propria persona) that the idea that there is something suspect about conspiracy theories is one of the most dangerous and idiotic superstitions to disgrace our political culture.

Wittgenstein’s experiments on rhythm (1912-13) were based on Charles Myers’s 1911 written protocols for laboratory exercises. The experiments provided an early onset for Wittgenstein’s career-long exploration of the philosophically pervasive implications of aspects. Years before the Tractatus, Wittgenstein already got a glimpse of a philosophical angle, which was bound to become very important to him not only in aesthetics, but also for his overarching philosophical development. He became interested in the possibilities of aesthetic conversation, in what we actually do (...) when we re-phrase, compare, come up with good similes in order to illuminate something definite within the space of possibility. These initial insights were bound to recede into the background for a while by the mounting demands of the Tractatus framework, only to fully bloom in Wittgenstein’s later work. (shrink)

This article provides a framework for understanding the dynamics between the disenchanting effects of a uniquely modern existential meaning crisis and a countervailing reenchantment facilitated by the techno-cultural movement of transhumanism. This movement constructs a post-secular techno-theology grounded in a transhumanist ontology that corresponds to a shift away from anthropocentric meaning systems. To shed light on this dynamic, I take a phenomenological approach to the human-technology relationship, highlighting the role of technology in ontology formation and religious imagination. I refer (...) to examples of transhumanist religious movements to illustrate a new posthumanist ontological grounding of meaning corresponding to a contemporary meaning-crisis that scholars are calling ‘neuroexistentialism.’ I then use the language of Charles Taylor and his work on secularization to frame these ontological developments. Ultimately, this article argues that transhumanist religious expression represents a zeitgeist of post-secular re-enchantment. (shrink)

This essay explores the possibility that religiously motivated intolerance and conflict can be reframed and positively utilized for constructive social-political purposes. After reviewing efforts by political philosophers over the past two decades to accommodate religious voices in political discourse, I scrutinize Charles Taylor’s attempt to improve upon the limits of “accommodationist” approaches to religious intolerance and conflict. I argue that both accommodationist and Taylor’s recognition-based approaches to religiously motivated conflict take the gravity of such conflict with insufficient seriousness. I (...) then explore the potential goods of intentional conflict by examining Chantal Mouffe’s account of agonistic pluralism as a proposal for thinking beyond tolerance as an orienting value for resolving intransigent conflict. While I argue that Mouffe’s account finally suffers from certain of the same misgivings as the accommodationist and recognition-based approaches, I conclude that agonistic pluralism’s aim to conceptually reframe (rather than eliminate) intolerance and conflict moves in an important and promising direction.

In this article, network science is discussed from a methodological perspective, and two central theses are defended. The first is that network science exploits the very properties that make a system complex. Rather than using idealization techniques to strip those properties away, as is standard practice in other areas of science, network science brings them to the fore, and uses them to furnish new forms of explanation. The second thesis is that network representations are particularly helpful in explaining the properties (...) of non-decomposable systems. Where part-whole decomposition is not possible, network science provides a much-needed alternative method of compressing information about the behavior of complex systems, and does so without succumbing to problems associated with combinatorial explosion. The article concludes with a comparison between the uses of network representation analyzed in the main discussion, and an entirely distinct use of network representation that has recently been discussed in connection with mechanistic modeling.

In this paper I shall explain how I came to realize that for as long as I believed that there exists an epistemic gap, or veil of perception, separating the world into that which is subjective and internal to the mind from that which is objective and external to the mind, I was unable to provide a compelling argument for the existence of this same Epistemic Gap ontology.

Antisemitism is fun. This essay explains why and proposes a new approach to combating it.

This paper describes one style of functional analysis commonly used in the neurosciences called task-bound functional analysis. The concept of function invoked by this style of analysis is distinctive in virtue of the dependence relations it bears to transient environmental properties. It is argued that task-bound functional analysis cannot explain the presence of structural properties in nervous systems. An alternative concept of neural function is introduced that draws on the theoretical neuroscience literature, and an argument is given to show that (...) this alternative concept of may help to overcome the explanatory limitations of task-bound functional analysis.

The ninth and tenth chapters of the Origin mark a profound, if perhaps difficult to detect, shift in the book’s argumentative structure. In the previous few chapters and in the ninth, Darwin has been exploring a variety of objections to natural selection, some more obvious (where are all the fossils of transitional forms?) and some showing careful attention to challenging consequences of evolution (could selection really produce instincts?). Starting in the tenth, however, Darwin turns to showing us what kinds of (...) new and unexpected results evolutionary theory might be able to offer us, again in domains both predictable (extinction) and unexpected (biogeography, embryology). It is notable that it is the fossil record that serves as this pivot point, being both a source of potentially powerful objections to evolutionary theory and home to some of its most compelling new explanations. In this chapter, I present both sets of arguments and consider what role Darwin gave to fossil evidence, in the process attempting to discover why it might have played this unique role in two different parts of Darwin’s “long argument” for evolution by natural selection. Geology’s special place, I argue, derives at least in part from its particular importance in Darwin’s social and intellectual context. (shrink)

Nous proposons une étude de la constitution du sens dans l'interaction humain-machine à partir des définitions que donnent Turing et Wittgenstein à propos de la pensée, la compréhension, et de la décision. Nous voulons montrer par l'analyse comparative des proximités et différences conceptuelles entre les deux auteurs que le sens commun entre humains et machines se co-constitue dans et à partir de l'action, et que c'est précisément dans cette co-constitution que réside la valeur sociale de leur interaction. Il s'agira pour (...) cela de problématiser l'interaction humain-machine autour de la question de ce que signifie « suivre une règle » pour définir et distinguer les modes interprétatifs et les comportements décisionnels de chacun. Nous en viendrons alors au constat que la mutualisation des signes qui s'opère à travers le dialogue humain-machine est au fondement de la constitution d'une société informatisée. (shrink)

Will brain imaging technology soon enable neuroscientists to read minds? We cannot answer this question without some understanding of the state of the art in neuroimaging. But neither can we answer this question without some understanding of the concept invoked by the term "mind reading." This article is an attempt to develop such understanding. Our analysis proceeds in two stages. In the first stage, we provide a categorical explication of mind reading. The categorical explication articulates empirical conditions that must be (...) satisfied if mind reading is to be achieved. In the second stage, we develop a metric for judging the proficiency of mind reading experiments. The conception of mind reading that emerges helps to reconcile folk psychological judgments about what mind reading must involve with the constraints imposed by empirical strategies for achieving it.

Substantially increased wealth inequality across the developed world has prompted many philosophers, economists and legal theorists to support comprehensive taxes on all forms of wealth. Proposals include levying taxes on the basis of total wealth, or alternatively the change in the value of capital holdings measured from year-to-year. This contrasts with most existing policies that tax capital assets at the point they are transferred from one beneficiary to another through sale or gifts. Are these tax reforms likely to meet their (...) aims of greater economic and political equality? We argue that these policies are likely to fail because, following neoclassical economic theory, they are based on a conception of capital as possessing given values in what amounts to a static equilibrium. This mischaracterizes the dynamic and subjective character of market economies and the contested value of real instantiations of capital goods. This makes them very difficult, often impossible, to value apart from at the point of voluntary transfer or profit realization. This means most taxes levied on a mark-to-market basis will be arbitrary and unfair. We propose alternative policies based on an income realization approach to taxation that are more likely to curb excessive wealth holdings. This includes introducing international treaties that prohibit preferential tax treatment for individual companies and specific sectors, and broadening the income tax base to include the imputed rent of personal housing wealth.

A longstanding issue in attempts to understand the Everett (Many-Worlds) approach to quantum mechanics is the origin of the Born rule: why is the probability given by the square of the amplitude? Following Vaidman, we note that observers are in a position of self-locating uncertainty during the period between the branches of the wave function splitting via decoherence and the observer registering the outcome of the measurement. In this period it is tempting to regard each branch as equiprobable, but we (...) argue that the temptation should be resisted. Applying lessons from this analysis, we demonstrate (using methods similar to those of Zurek's envariance-based derivation) that the Born rule is the uniquely rational way of apportioning credence in Everettian quantum mechanics. In doing so, we rely on a single key principle: changes purely to the environment do not affect the probabilities one ought to assign to measurement outcomes in a local subsystem. We arrive at a method for assigning probabilities in cases that involve both classical and quantum self-locating uncertainty. This method provides unique answers to quantum Sleeping Beauty problems, as well as a well-defined procedure for calculating probabilities in quantum cosmological multiverses with multiple similar observers.

Conspiracy theories should be neither believed nor investigated - that is the conventional wisdom. I argue that it is sometimes permissible both to investigate and to believe. Hence this is a dispute in the ethics of belief. I defend epistemic ‘oughts’ that apply in the first instance to belief-forming strategies that are partly under our control. I argue that the policy of systematically doubting or disbelieving conspiracy theories would be both a political disaster and the epistemic equivalent of self-mutilation, since (...) it leads to the conclusion that history is bunk and the nightly news unbelievable. In fact (of course) the policy is not employed systematically but is only wheeled on to do down theories that the speaker happens to dislike. I develop a deductive argument from hard-to-deny premises that if you are not a ‘conspiracy theorist’ in my anodyne sense of the word then you are an ‘idiot’ in the Greek sense of the word, that is, someone so politically purblind as to have no opinions about either history or public affairs. The conventional wisdom can only be saved (if at all) if ‘conspiracy theory’ is given a slanted definition. I discuss some slanted definitions apparently presupposed by proponents of the conventional wisdom (including, amongst others, Tony Blair) and conclude that even with these definitions the conventional wisdom comes out as deeply unwise. I finish up with a little harmless fun at the expense of David Aaronvitch whose abilities as a rhetorician and a popular historian are not perhaps matched by a corresponding capacity for logical thought.

Kierkegaard’s ideal supports a radical form of “deep diversity,” to use Charles Taylor’s expression. It is radical because it embraces not only irreducible conceptions of the good but also incompatible ones. This is due to its paradoxical nature, which arises from its affirmation of both monism and pluralism, the One and the Many, together. It does so in at least three ways. First, in terms of the structure of the self, Kierkegaard describes his ideal as both unified (the “positive (...) third”) and plural (a “negative unity”). Second, he affirms a process which brings together unity, as implied by the linear notion of “stages”, with plurality, in the form of “spheres of existence” (aesthetic, ethical, and religious). And third, the culmination of the process implies that we should embrace both a unified dialectic (“Religiousness A”) alongside the plural remnants of the ethical/aesthetic, that is, both the infinity of the former and the finitudes of the latter. Unsurprisingly, while Kierkegaard describes those who are able to exemplify his ideal in practice as “always joyful,” he also considers the ideal to be “extremely hard, the hardest task of all.” This is why those such as Hubert L. Dreyfus are wrong to claim that it provides an experience of bliss; on the contrary, those who realize it “are always in danger.” As I shall show, one form this danger takes is that it threatens to dirty the hands of those who manage to uphold Kierkegaard’s ideal. Moreover, it does so in ways that, I claim, tend to be missed by Kierkegaard himself. Nevertheless, the danger is also essential to the creativity of his approach, and I conclude by pointing out how this creativity makes it capable of tackling one of the profoundest challenges in contemporary ethics: that arising from what just war theorists call a “supreme emergency.” .

A paradox, it is claimed, is a radical form of contradiction, one that produces gaps in meaning. In order to approach this idea, two senses of “separation” are distinguished: separation by something and separation by nothing. The latter does not refer to nothing in an ordinary sense, however, since in that sense what’s intended is actually less than nothing. Numerous ordinary nothings in philosophy as well as in other fields are surveyed so as to clarify the contrast. Then follows the (...) suggestion that philosophies which one would expect to have room for paradoxes actually tend either to exclude them altogether, or to dull them. There is a clear alternative, however, one that fully recognizes paradoxes and yet also strives to overcome them. (shrink)

Nietzsche's writing style is designed to elicit affective responses in his readers. Humour is one of the most common means by which he attempts to engage his readers' affects. In this article, I explain how and why Nietzsche uses humour to achieve his philosophical ends. The article has three parts. In part 1, I reject interpretations of Nietzsche's humour on which he engages in self‐parody in order to mitigate the charge of decadence or dogmatism by undermining his own philosophical authority. (...) In part 2, I look at how Nietzsche uses humour and laughter as a critical tool in his polemic against traditional morality. I argue that one important way in which Nietzsche uses humour is as a vehicle for enhancing the effectiveness of his ad hominem arguments. In part 3, I show how Nietzsche exploits humour's social dimension in order to find and cultivate what he sees as the right kinds of readers for his works. (shrink)

Research and engineering in the quantum domain involve long chains of activity involving theory development, hypothesis formation, experimentation, device prototyping, device testing, and many more.

It provides a controlled vocabulary, built out of terms that are (...) designed to be maximally comprehensible to all groups of stakeholders and across all the sub-fields of the quantum domain.

There are a bewildering variety of claims connecting Darwin to nineteenth-century philosophy of science—including to Herschel, Whewell, Lyell, German Romanticism, Comte, and others. I argue here that Herschel’s influence on Darwin is undeniable. The form of this influence, however, is often misunderstood. Darwin was not merely taking the concept of “analogy” from Herschel, nor was he combining such an analogy with a consilience as argued for by Whewell. On the contrary, Darwin’s Origin is written in precisely the manner that one (...) would expect were Darwin attempting to model his work on the precepts found in Herschel’s Preliminary Discourse on Natural Science. While Hodge has worked out a careful interpretation of both Darwin and Herschel, drawing similar conclusions, his interpretation misreads Herschel’s use of the vera causa principle and the verification of hypotheses. The new reading that I present here resolves this trouble, combining Hodge’s careful treatment of the structure of the Origin with a more cautious understanding of Herschel’s philosophy of science. This interpretation lets us understand why Darwin laid out the Origin in the way that he did and also why Herschel so strongly disagreed, including in Herschel’s heretofore unanalyzed marginalia in his copy of Darwin’s book.

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)

Conpiracy theories are widely deemed to be superstitious. Yet history appears to be littered with conspiracies successful and otherwise. (For this reason, "cock-up" theories cannot in general replace conspiracy theories, since in many cases the cock-ups are simply failed conspiracies.) Why then is it silly to suppose that historical events are sometimes due to conspiracy? The only argument available to this author is drawn from the work of the late Sir Karl Popper, who criticizes what he calls "the conspiracy theory (...) of society" in The Open Society and elsewhere. His critique of the conspiracy theory is indeed sound, but it is a theory no sane person maintains. Moreover, its falsehood is compatible with the prevalence of conspiracies. Nor do his arguments create any presumption against conspiracy theories of this or that. Thus the belief that it is superstitious to posit conspiracies is itself a superstition. The article concludes with some speculations as to why this superstition is so widely believed. (shrink)

Computer-based argument mapping greatly enhances student critical thinking, more than tripling absolute gains made by other methods. I describe the method and my experience as an outsider. Argument mapping often showed precisely how students were erring (for example: confusing helping premises for separate reasons), making it much easier for them to fix their errors.

I discuss several variations (...) of this strategy, interpreting “conspiracy theory” in different ways but conclude that on all these readings, the conventional wisdom is deeply unwise. (shrink)

The propensity interpretation of fitness (PIF) is commonly taken to be subject to a set of simple counterexamples. We argue that three of the most important of these are not counterexamples to the PIF itself, but only to the traditional mathematical model of this propensity: fitness as expected number of offspring. They fail to demonstrate that a new mathematical model of the PIF could not succeed where this older model fails. We then propose a new formalization of the PIF that (...) avoids these (and other) counterexamples. By producing a counterexample-free model of the PIF, we call into question one of the primary motivations for adopting the statisticalist interpretation of fitness. In addition, this new model has the benefit of being more closely allied with contemporary mathematical biology than the traditional model of the PIF. (shrink)

The problem of “dirty hands” concerns the possibility that there are situations in which, no matter what one does, there is no way to avoid committing a moral wrong. By presenting a taxonomy, this paper contends that the different ways of responding to the problem correspond to different positions as regards the classic metaphysical theme of “the One and the Many.” It is then suggested that the best, because most realistic, response aligns with an approach that would have us move (...) “towards One, as Many.”.

This paper contrasts five contemporary political philosophies – neutralism, postmodernism, pluralism, anarchism, and patriotism – and argues that the latter is superior. This is because of how patriotism relates to the various political ideologies, including liberalism, conservatism, socialism, nationalism, feminism, and so on.

Hume describes his own “open, social, and cheerful humour” as “a turn of mind which it is more happy to possess, than to be born to an estate of ten thousand a year.” Why does he value a cheerful character so highly? I argue that, for Hume, cheerfulness has two aspects—one manifests as mirth in social situations, and the other as steadfastness against life’s misfortunes. This second aspect is of special interest to Hume in that it safeguards the other virtues. (...) And its connection with the first aspect helps explain how it differs from Stoic tranquility. For Hume, I argue, philosophy has a modest role in promoting human happiness by preserving cheerfulness. (shrink)

There has been much debate regarding the 'double-effect' of sedatives and analgesics administered at the end-of-life, and the possibility that health professionals using these drugs are performing 'slow euthanasia.' On the one hand analgesics and sedatives can do much to relieve suffering in the terminally ill. On the other hand, they can hasten death. According to a standard view, the administration of analgesics and sedatives amounts to euthanasia when the drugs are given with an intention to hasten death. In this (...) paper we report a small qualitative study based on interviews with 8 Australian general physicians regarding their understanding of intention in the context of questions about voluntary euthanasia, assisted suicide and particularly the use of analgesic and sedative infusions (including the possibility of voluntary or non-voluntary 'slow euthanasia'). We found a striking ambiguity and uncertainty regarding intentions amongst doctors interviewed. Some were explicit in describing a 'grey' area between palliation and euthanasia, or a continuum between the two. Not one of the respondents was consistent in distinguishing between a foreseen death and an intended death. A major theme was that 'slow euthanasia' may be more psychologically acceptable to doctors than active voluntary euthanasia by bolus injection, partly because the former would usually only result in a small loss of 'time' for patients already very close to death, but also because of the desirable ambiguities surrounding causation and intention when an infusion of analgesics and sedatives is used. The empirical and philosophical implications of these findings are discussed. (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.

In this paper I raise concerns that I have with what I perceive to be as a complete lack of warrant for Hume’s assertion that there are only two types of reasoning – demonstrative and probable. (Hume’s fork) What I leave for others to decide is whether this lack of warrant therefore successfully undercuts Hume’s argument for the Problem of Induction.

My aim here is to make sense of Plato's account of desire in the middle dialogues. To do that I need to unify or reconcile what are at first sight two quite different accounts: the doctrine of eros in the Symposium and the tripartite theory of motivation in the Republic. It may be that the two theories are after all irreconcilable, that Plato simply changed his mind on the nature of human desire after writing the Symposium and before composing the (...) Republic. But that conclusion can be justified only if attempts to reconcile the two theories end in failure. The attempt must be made first. (shrink)

The idea of ‘reversion’ or ‘atavism’ has a peculiar history. For many authors in the latenineteenth and early-twentieth centuries – including Darwin, Galton, Pearson, Weismann, and Spencer, among others – reversion was one of the central phenomena which a theory of heredity ought to explain. By only a few decades later, however, Fisher and others could look back upon reversion as a historical curiosity, a non-problem, or even an impediment to clear theorizing. I explore various reasons that reversion might have (...) appeared to be a central problem for this first group of figures, focusing on their commitment to a variety of conceptual features of evolutionary theory; discuss why reversion might have then ceased to be an interesting phenomenon; and, finally, close with some more general thoughts about the death of scientific problems.

Qualitative evidence concerning the relationship between QoL and a wide range of disabilities suggests that subjective judgments regarding other people’s QoL are wrong more often than not and that such judgments by medical practitioners in particular can be biased. Guided by their desire to do good and avoid harm, surgeons often rely on "the eyeball test" to decide whether a patient will or will not benefit from surgery. But the eyeball test can easily harbor a range of implicit judgments and (...) biases against patients with disabilities, including erroneous assumptions about QoL. We critique the use of the "eyeball" test and offer suggestions to reduce bias and ensure that patients’ values are more consistently prioritized in surgical decision-making. (shrink)

John Rawls’ gamification of justice leads him – along with many other monist political philosophers, not least Ronald Dworkin – to fail to take politics seriously enough. I begin with why we consider games frivolous and then show how Rawls’ theory of justice is not merely analogous to a game, as he himself seems to claim, but is in fact a kind of game. As such, it is harmful to political practice in two ways: one as regards the citizens who (...) participate directly in it, and the other as regards those who do no more than follow it. Similar harms, I then argue, come from taking politics too seriously, which is the attitude I ascribe to pluralist political philosophers such as Isaiah Berlin, Stuart Hampshire, and Bernard Williams. To them, the plural, incommensurable nature of values means that they cannot be reconciled and so that politics must be a matter of negotiating dirty, and often tragic, compromises. What we need instead, I conclude, is a third way, one that is neither monist nor pluralist but in-between the two extremes. (shrink)
