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: 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: 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 : 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: When considering normative concepts, such as distributive justice, one must consider both the question how concepts can have normative force and which particular conceptions of these concepts have this normative force. In this article I consider the view that the human capacity for autonomy accounts for normativity, and argue that adopting this view commits one to a responsibility-sensitive theory of distributive justice. This conclusion puts me directly at odds with the work of John Rawls, who derives his responsibility-insensitive difference principle from a similar account of autonomy. However, I argue that such an argument would be based on a mischaracterisation of what is significant about the human capacity for autonomy.

ABSTRACT: In this paper, I raise the following question: can the ethical thought of Jurgen Habermas and Karl-Otto Apel provide us with a way of showing that morality is a rational requirement? The answer I give is that (unfortunately) it cannot. I argue for this claim by showing that a decisive objection to Alan Gewirth’s line of thought in Reason and Morality also applies to discourse ethical arguments that try to show an inescapable commitment to a moral principle.
