Challenging, with several powerful arguments, some of our deepest beliefs about rationality, morality, and personal identity, Parfit claims that we have a false view about our own nature. It is often rational to act against our own best interersts, he argues, and most of us have moral views that are self-defeating. We often act wrongly, although we know there will be no one with serious grounds for complaint, and when we consider future generations it is very hard to avoid conclusions (...) that most of us will find very disturbing.

Repeatedly and successfully, the celebrated Harvard philosopher Robert Nozick has reached out to a broad audience beyond the confines of his discipline, addressing ethical and social problems that matter to every thoughtful person. Here Nozick continues his search for the connections between philosophy and "ordinary" experience. In the lively and accessible style that his readers have come to expect, he offers a bold theory of rationality, the one characteristic deemed to fix humanity's "specialness." What are principles for? asks Nozick. We (...) could act simply on whim, or maximize our self-interest and recommend that others do the same. As Nozick explores rationality of decision and rationality of belief, he shows how principles actually function in our day-to-day thinking and in our efforts to live peacefully and productively with each other. Throughout, the book combines daring speculations with detailed investigations to portray the nature and status of rationality and the essential role that imagination plays in this singular human aptitude.

Can we understand what makes someone the same person without understanding what it is to be a person? Prereflectively we might not think so, but philosophers often accord these questions separate treatments, with personal-identity theorists claiming the first question and free-will theorists the second. Yet much of what is of interest to a person—the possibility of survival over time, compensation for past hardships, concern for future projects, or moral responsibility—is not obviously intelligible from the perspective of either question alone. Marya (...) Schechtman encourages us to adopt a more unified perspective. (shrink)

Images of myself being Napoleon can scarcely merely be images of the physical figure of Napoleon.... They will rather be images of, for instance, the desolation at Austerlitz as viewed by me vaguely aware of my short stature and my cockaded hat, my hand in my tunic.

Marya Schechtman takes issue with analytic philosophy's emphasis on the first sort of question to the exclusion of the second.

Two centuries after they were published, Kant's ethical writings are as much admired and imitated as they have ever been, yet serious and long-standing accusations of internal incoherence remain unresolved. Onora O'Neill traces the alleged incoherences to attempts to assimilate Kant's ethical writings to modern conceptions of rationality, action and rights. When the temptation to assimilate is resisted, a strikingly different and more cohesive account of reason and morality emerges. Kant offers a "constructivist" vindication of reason and a moral vision (...) in which obligations are prior to rights and in which justice and virtue are linked. O'Neill begins by reconsidering Kant's conceptions of philosophical method, reason, freedom, autonomy and action. She then moves on to the more familiar terrain of interpretation of the Categorical Imperative, while in the last section she emphasizes differences between Kant's ethics and recent "Kantian" ethics, including the work of John Rawls and other contemporary liberal political philosophers.

Just as there are rational requirements on thought, there are rational requirements on action. This book defends a conception of ethics, and a related conception of human nature, according to which altruism is included among the basic rational requirements on desire and action. Altruism itself depends on the recognition of the reality of other persons, and on the equivalent capacity to regard oneself as merely one individual among many.

Hume said that the reasons that determine the rationality of one's actions are the desires one has when acting: one's actions are rational iff they advance these desires. Thomas Nagel says this entails calling rational, actions absurdly conflicting in aims over time. For one might have reason, in one's current desires, to begin trying to cause states one foresees having reason, in one's foreseen desires, to prevent. Instead, then, real reasons must be timeless, so that current and foreseen reasons cannot (...) conflict. I say the desire theory does not have absurd consequences. A rational agent's desires would rationally evolve, never requiring actions conflicting in aims over time, except where it was instrumentally rational for her to change in her desires, whence such conflicts are rationally appropriate. Further, whatever sorts of things count as real reasons, since reasons can rationally require their own revision, they cannot be necessarily timeless. (shrink)

Theories of rational choice focus on the question of how to choose what to do. They are, that is, concerned with the selection of one among a set of possible actions. Furthermore, they tell us how to make such a choice rationally. They accomplish this aspect of their task by telling us how to choose ‘in order to achieve our aims as well as possible.’Theories of reasonable deliberation, as I describe them in this paper, analyze a different domain of reasoning (...) in the service of action. First, their subject matter is the deliberation that leads to action, rather than the final selection of the action itself. Second, they ask about the intrinsic character of a deliberative path, rather than its likely outcome. That is, they are theories of the reasonableness of deliberation, rather than its rationality. To see the distinctiveness of this theoretical domain, it helps to approach it by backing away from the domain of rational choice theories one step at a time. (shrink)

Prudence and authenticity are sometimes seen as rival virtues. Prudence,as traditionally conceived, is temporally neutral. It attaches no intrinsic significance to the temporal location of benefits or harms within the agent’s life; the prudent agent should be equally concerned about all parts of her life. But people’s values and ideals often change over time, sometimes in predictable ways, as when middle age and parenthood often temporize youthful radicalism or spontaneity with concerns for comfort,security, and predictability. In situations involving diachronic, intrapersonal (...) conflicts of value, prudence—in particular,temporal neutrality—appears to require the agent to subordinate her current ideals to her future ones or at least to moderate pursuit of current ideals in light of future ones. But this demand may seem to sacrifice authenticity, if we suppose that authenticity requires acting on the ideals that the agent reflectively and sincerely accepts at the time of action. This tension between prudence and authenticity raises interesting questions about temporal neutrality, the structure of intrapersonal conflicts of value, the nature of ideals, and the demands of authenticity. After examining various aspects of this puzzle, I defend the commitments of prudence in situations involving intrapersonal value conflict and argue that authenticity—understood as being true to oneself— actually supports temporal neutrality. I conclude by suggesting how this defense of prudence lends credibility to the more general demand of temporal neutrality. (shrink)
