It is almost commonplace to suggest that what is morally right for one person to do must also be right for anyone else similarly situated. The author suggests that this "universalization requirement" applies to only a limited sphere of the moral life, chiefly to duties of perfect obligation. Extending the requirement beyond this sphere fails to leave room for human freedom in vocation or for a clear recognition of human finitude.

This paper introduces the author's approach to everyday ascriptions of collective cognitive states as in such statements as we believe he is lying. Collective epistemology deals with these ascriptions attempting to understand them and the phenomena in question.

This paper argues that A-determinations (past, present, and future) and B-relations (simultaneity and succession) have the same empirical status in that they are all neither historically discoverable nor sensible, but are detectable and are detectable in the same way. This constitutes a reason for thinking they are in the same class with respect to objectivity, contrary to the Russellian view that “in a world in which there was no experience there would be no past, present, or future, but there might (...) well be earlier and later.” The argument is developed to furnish an explanation of how in fact (and contra McTaggart) we are “immediately certain of the reality of time,” the explanation being that we detect time.

Two radically different, general accounts of human character traits - the "essentialist" and the "summary" accounts - are given critical consideration. The former account is characterized in terms of Saul Kripke's conception of metaphysical essence. Both accounts are discussed with reference to Jean-Paul Sartre's treatment of character traits. The essentialist account cannot withstand considerations relating to personal identity over time. The summary account is also rejected, as is a certain kind of dispositional account. An approach to at least some character (...) traits in terms of persisting aims, beliefs, and so on is recommended. (shrink)

I argue that obligations of an important type inhere in what I call 'joint commitments'. I propose a joint commitment account of everyday agreements. This could explain why some philosophers believe that we know of the obligating nature of agreements a priori. I compare and contrast obligations of joint commitment with obligations in the relatively narrow sense recommended by H. L. A. Hart, a recommendation that has been influential. Some central contexts in which Hart takes there to be obligations in (...) his sense are contexts in which there are obligations of joint commitment. Nonetheless, different senses of 'obligation' appear to be at issue. (shrink)

In a time of intensified interest in an "ethic of virtue," Josef Pieper stands out as one who has pondered and written about the virtues for many years. This paper explores some aspects of Pieper's thought about the virtues and focuses especially on four problems: (1) the question of the unity of the virtues; (2) the relation between natural and theological virtues; (3) the dangers for Christian ethics of picturing virtue as habitual; and (4) the question whether virtue needs any (...) reward beyond virtue itself.

At a time when a "return to Sartre" is being heralded in France and elsewhere in preparation for the celebration of the centennial of his birth, it seems appropriate to ponder the nature and tenor of this renewal. To which aspects of Sartre's work are we returning as the centennial approaches, and are we doing so with fresh eyes or with the same critical prejudices that have obscured our appreciation of this work in the past? If one looks for answers (...) to Bernard-Henri Lévy (aka BHL), the principal instigator of this current renewal, with specific regard to the genre that interests us in these pages—the theater—one is going to be sorely disappointed. For while Lévy considers Sartre "the first [writer]—the only [writer]—to know how to split himself equally well between being a theoretician and an accomplished storyteller," he lavishes this praise solely on the theory and practice of Sartre's novels: "The concept of engagement is not a political concept stressing the social duties of the writer; it is a philosophical concept highlighting the metaphysical powers of language. … Sartre … has never really written a novel with a [totalizing] thesis or message" (BHL 85, 86).

The use of computer simulation for building theoretical models in social science is introduced. It is proposed that agent-based models have potential as a “third way” of carrying out social science, in addition to argumentation and formalisation. With computer simulations, in contrast to other methods, it is possible to formalise complex theories about processes, carry out experiments and observe the occurrence of emergence. Some suggestions are offered about techniques for building agent-based models and for debugging them. A scheme for structuring (...) a simulation program into agents, the environment and other parts for modifying and observing the agents is described. The article concludes with some references to modelling tools helpful for building computer simulations. (shrink)

Maestripieri et al. provide an important service in highlighting prosocial biases toward attractive people from a cross-disciplinary perspective. Here I comment on the conceptual and critical side of their review of evolutionary psychology studies. I propose that further work should be focused on understanding the role of signaling in prosocial behavior.
