ABSTRACT : Definitions of cooperative action usually provide sufficient rather than necessary conditions. I here define a minimal form of cooperation, which encompasses mass actions, such as demonstrations. Intentional, epistemic, strategic and teleological aspects, mainly obtained from a weakening of pre-existing concepts, are discussed. I also emphasize the key role played by game theoretic concepts in the definition of joint action. Finally, I claim that rationality is a necessary condition of minimal cooperation, whereas classical analysis merely sees rationality as a possible or desirable characteristic.

ABSTRACT: It is argued that the equivalence, which is usually postulated to hold between infinite descent and transfinite induction in the foundations of arithmetic uses the law of excluded middle through the use of a double negation on the infinite set of natural numbers and therefore cannot be admitted in intuitionistic logic and mathematics, and a fortiori in more radical constructivist foundational schemes. Moreover it is shown that the infinite descent used in Dedekind-Peano arithmetic does not correspond to the infinite descent of classical Fermatian arithmetic or number theory. However, from the point of view of classical logic, the principles of complete induction and transfinite induction, the least number principle and infinite descent are all equivalent. We find here a focal point for a foundational critique that aims for a a clarification of philosophical options in the foundations of logic and mathematics.

ABSTRACT: In this paper, I revisit arguments for and against various theses concerning higher-order knowledge in order to fully gauge their impact on the principles of positive and negative introspection. I argue that the expression “knowing that one knows” has at least two salient understandings: the more common one, labelled “transparentist”, validates the principle of positive introspection, while the other which is less common, labelled “agrippean”, supports some of the arguments against this principle.

ABSTRACT: Since Goodman’s classic monograph (1954), it has been known that any reasonable theory of induction must involve non formal elements. However, the right to make theoretical use of such an element comes with responsibilities. This article argues for an apparently new desideratum for a theory of induction: namely, that it accounts for the dynamics of the non formal element used. None of the main existing theories of induction satisfies this desideratum. The recognition of the importance of dynamics does however have the advantage of suggesting where to look for a more acceptable and complete theory of induction.

ABSTRACT: David Braybrooke argues that the core of the natural law theory of Thomas Aquinas survived in the work of Hobbes, Locke, Hume, and Rousseau. Much to my surprise, Braybrooke argues as well that David Copp’s society-centered moral theory is a secular version of this same natural law theory. Braybrooke makes a good case that there is an important idea about morality that is shared by the great philosophers in his group and that this idea is also found in Copp’s work. The idea is captured by the Functionalist Thesis, the thesis that moral propositions are made true by facts about what, given the nature of human beings and their circumstances, enables people to live together in thriving communities. I argue that Copp can accept Braybrooke’s suggestion and use it to improve his formulation of the basic idea of the society-centered theory.

ABSTRACT: Recent evolutionary thinking suggests that morality may have three distinct roots, corresponding to the three “master concepts” in the history of philosophical ethics: sympathy, virtue, and duty. Evolutionary biologists are nearly unanimous in the view that there are two distinct mechanisms that can generate altruism in other animal species, and there is increasing recognition that there must be a third mechanism at work among humans. Altruism in the biological sense is not the same thing as morality, but it is a precursor to morality. An examination of such precursors can help us gain a deeper understanding of morality proper.

ABSTRACT: The cluster theory of names is generally thought to have been to have been utterly discredited by the objections raised against it by Kripke in Naming and Necessity. In this paper, I develop a new version of the cluster theory in which the role played by clusters of associated descriptions is occupied by teams of cognitive relations. And I argue that these teams of relations find a home in an account of the meanings of expressions in epistemic sentence frames, and in a more general theory of the reference of proper names.

ABSTRACT: Qualia, the subjectively known qualities of conscious experience, are judged by many philosophers and scientists to lie beyond the domain of scientific explanation, thus making the conscious mind partly incomprehensible to the objective physical sciences. Some, like Kripke and Chalmers, employ modal logic to argue that explanations of qualia are impossible in principle. I argue that there already exist perfectly normal scientific explanations of qualia, and rebut the arguments of those who deny this possibility.

ABSTRACT: There are some problems with Lynne Baker’s constitution account of personal identity that become evident when we consider brain transplant thought experiments and two kinds of rare cases of conjoined twins — the first appears to be one organism but two persons and the second seems to involve two organisms associated with one person. To handle the problems arising from brain transplants, the constitution theorist must admit an additional level of constitution between the organism and the person. To resolve the problems posed by the two kinds of conjoined twins, the constitution theorist must accept that constitution is not always a one-to-one relationship.

ABSTRACT: Individual rational judgment, of the kind required for justification in cognition or morals, is fundamentally socially and historically conditioned. I argue for this by defending key themes from Kant’s and Hegel’s accounts of rational judgment and justification, including the “autonomy” of rational judgment and one key point of Hegel’s account of “mutual recognition.” These themes are rooted in Kant’s and Hegel’s transformation of the modern natural law tradition, which originates the properly pragmatic account of rationality, which affords genuine rational justification, and which provides for realism about the objects of empirical knowledge and strict objectivity about moral norms.

ABSTRACT: In this paper I argue that John McDowell’s objections to Philipa Foot’s ethical naturalism do not justify a rejection of her views, but only clarifies what we can defensibly take from her position. Moreover, his comments suggest a way in which Foot’s naturalism may help to secure the realism McDowell defends in his own work. In seeing how Foot’s naturalism can reassure us of the reality of ethical reasons, we can understand how McDowell needs something like Foot’s naturalism in order to redeem his own realist aspirations for ethics.

ABSTRACT: I offer a refutation of the standard argument according to which we have no doxastic obligation because we do not have the kind of voluntary control over our beliefs required for having obligations. I then propose an interpretation of the distinction between epistemic and practical reasons for belief which can be generalised to other attitudes such as intention, and seems to imply (i) that mental acts such as judgements and decisions never count as intentional actions, and (ii) that these two sorts of reasons are incommensurable.

ABSTRACT: The traditional conception of experience — also known as the causal conception — has been criticised in the last thirty years or so by proponents of the disjunctive conception. This article examines an argument recently put forward by John McDowell in support of disjunctivism. Broadly speaking, his argument can be seen as an attempt to show that, unlike the disjunctive conception, the traditional conception cannot account for a crucial aspect of experience. I aim here to show that McDowell’s argument — which is of a transcendental kind — does not have sufficient resources to achieve its intended goal.

ABSTRACT: In the logical tradition of analytical philosophy, to understand the meaning of an utterance is to understand its truth conditions. In the tradition of natural language analysis, meaning is related to language use. Since Grice, meaning is linked to speakers’ attitudes and actions. Following Austin, Searle, and Vanderveken, to mean is to use words with the intention of performing illocutionary acts. Such acts have felicity conditions instead of truth conditions. The aim of my work is to clarify the nature of meaning in the second tradition. In my view, to mean something is mainly to attempt to perform illocutionary acts. Any attempt is an intentional action rather than an attitude.

ABSTRACT: In Die Frage nach dem Ding, Martin Heidegger characterizes Galileo as an important transitional figure in the struggle to replace the Aristotelian conception of nature with that of Newton. However, Heidegger only attends to Galileo’s modernity and not to those Aristotelian elements still discernible in Galileo’s work. This article fleshes out both aspects in Galileo in light of Heidegger’s discussion. It concludes by arguing that the lacuna in Heidegger’s account of Galileo is the consequence of Heidegger’s own self-conscious modernity − a modernity that he slyly hints at in a remark he makes in FD concerning Galileo and Democritus.

ABSTRACT : A thesis held by John Searle, Hubert Dreyfus and Charles Taylor is that there is a kind of “understanding” or “knowledge” that differs from ordinary knowledge in being by nature non-representational or non-conceptual and rather a kind of “know-how.” The aim of this article is to examine the argument in support of their common thesis (which I call the “regress argument”) and their claim that it was endorsed, at least implicitly, by Wittgenstein in the Philosophical Investigations. This examination shows that the argument is not convincing and that Wittgenstein would have rejected it.

ABSTRACT: In Ideal Code, Real World, Brad Hooker seeks to offer a version of ideal rule consequentialism that is immune from standard criticisms. I will attempt to challenge Hooker’s ideal rule-consequentialist theory by arguing that there are philosophical problems at the ultimate foundation of his maximizing consequentialist and pluralist approach toward well-being and other basic goods. I find that no amount of revision is likely to insulate his approach from standard criticisms. I suggest that any maximizing rule-consequentialist approach toward well-being, taken in a rich and pluralist sense, is likely to fall prey to standard criticisms. In later work, Hooker drops ideal rule consequentialism in favor of an incremental rule-consequentialist approach. That piecemeal approach is also challenged in this paper.

ABSTRACT: Are individual citizens of imperfect democracies morally responsible for unjust wars waged by their state? Moral responsibility for unjust wars involves both retrospective and social responsibility. Citizens of imperfect democracies are retrospectively responsible when they choose to vote for a leader they know will wage an unjust war. This situation may occur very rarely. For example, US citizens did not have this political option at the outset of the Vietnam and Iraq Wars. However, even when citizens are not retrospectively responsible they have the social responsibility to engage in collective action to address the harms unjust war causes.

ABSTRACT: In his recent collection of essays, Language, Truth and History (2005), Donald Davidson appears to endorse a philosophy of language which gives primary importance to the notion of the speaker’s communicative intentions, a perspective on language not too dissimilar from that of Paul Grice. If that is right, then this would mark a major shift from the formal semanticist approach articulated and defended by Davidson in his Inquiries into Truth and Interpretation (1984). In this paper, I argue that although there are many similarities between these two thinkers, Davidson has not abandoned his earlier views on language

ABSTRACT: In Treatise 1.4.4, on behalf of modern philosophers, Hume described a causal argument that shows that our impressions of secondary qualities do not resemble qualities of objects themselves. However, in their respective arguments, Hume’s philosophical predecessors did not argue causally, but appealed to contrary qualities. I argue that Hume’s presentation was not simply a “gratuitous” stylistic difference, but an important correction of his predecessors in light of his own philosophical discoveries.
