Argues that practical irrationality is akin to moral culpability: it is defective practical thought which one could legitimately have been expected to avoid. It is thus a mistake to draw too tight a connection between failure to be moved by reasons and practical irrationality (as in a certain kind of "internalism"): one's failure may be genuine, but not culpable, and therefore not irrational.

Argues that, in acting for a reason, one takes that reason to explain one's action, not to justify it: reasons for acting need not be seen "under the guise of the good". The argument turns on the need to explain the place of "practical knowledge" - knowing what one is doing - in intentional action. A revised and expanded version of this material appears in Part One of "Reasons without Rationalism" (Princeton, 2007).

I develop and argue for a kind of externalism about certain kinds of non-doxastic attitudes that I call policy externalism. Policy externalism about a given type of attitude is the view that all the reasonable policies for having attitudes of that type will not involve the agent's beliefs that some relevant conditions obtain. My defense primarily involves attitudes like hatred, regret, and admiration, and has two parts: a direct deductive argument and an indirect linguistic argument, an inference to the best (...) explanation of some strange ways we use certain conditionals. The main thought throughout is that attitudes we reason with, like belief, are very different from attitudes we don't reason with, in a way that constrains the former but not the latter. Finally, I investigate some consequences of policy externalism, including that it secures the possibility of genuine conditional apologies. (shrink)

Standard discussions of prudence treat it as requiring time-slice management. That this is the standard view of prudence can be seen by its presence in two seemingly opposed positions on prudence, those of Thomas Nagel and Derek Parfit. I argue that this kind of view fails to properly appreciate the difficulty with being prudent, treating imprudence as a kind of theoretical mistake. I then offer a characterization of prudence as integrity, the holding together of disparate but temporally extended parts of (...) the self in a manner that makes the act of reasoning possible.

There has been a long tradition of interpreting Plato as a rational egoist. Over the past few decades, however, some scholars have challenged this reading. While Rational Egoism appeals to many ordinary folk, in sophisticated philosophical circles it has fallen out of favor as a general and complete account of the nature of reasons for action. I argue that while the theory of practical rationality that is often equated with rational egoism—a view that I call ‘Simple-Minded Rational Egoism'—is neither plausible (...) nor endorsed by Plato in his Republic, there is a more complex version of Rational Egoism to which Plato is indeed committed. Moreover, such a conception of practical rationality is not vulnerable to the standard set of objections that contemporary philosophers have made against Rational Egoism. (shrink)

Una vez que el foco de la reflexión pasa de las teorías ideales a la aplicación de la justicia social, centrada en las instituciones de las sociedades democráticas, se requiere prestar especial atención a los estilos de vida. Estos tienen una alta incidencia en cómo la justicia es realizada y afectan tanto a la desigualdad económica como a la disponibilidad de los recursos naturales. En nuestras sociedades es posible establecer restricciones a los estilos de vida, especialmente en aquellos casos en (...) que, por el efecto de algunas dinámicas sociales, aquellos se desacoplan de las concepciones del bien. Se defiende que, en tales casos, la base normativa que permite exigir el respeto a los estilos de vida se disuelve y por ello es posible justificar su restricción. (shrink)

Concern with ethical anthropocentrism has largely been confined to debates in animal and environmental ethics. Philosophers generally have shown little interest in it. Ethical egoism, by contrast, though usually rejected, has sparked wide philosophical interest. This is surprising, for the two are akin; anthropo-centrism is egoism writ large – the egoism of the human species. This paper explains the kinship by articulating this analogy, shows that the analogy provides for each argument for or against ethical egoism an analogous argument for (...) or against ethical anthropocentrism, and demonstrates the analogy's fruit-fulness by using it to extrapolate from an existing argument against ethical egoism a novel argument against ethical anthropocentrism.
