Moral theory has mostly focused on idealized situations in which the morally relevant properties of human actions can be known beforehand. Here, a framework is proposed that is intended to sharpen moral intuitions and improve moral argumentation in problems involving risk and uncertainty. Guidelines are proposed for a systematic search of suitable future viewpoints for hypothetical retrospection. In hypothetical retrospection, a decision is evaluated under the assumption that one of the branches of possible future developments has materialized. This evaluation is (...) based on the deliberator’s present values, and each decision is judged in relation to the information available when it was taken. The basic decision rule is to choose an alternative that comes out as morally acceptable (permissible) from all hypothetical retrospections. (shrink)

This paper defends Humeanism: the view that an agent has a reason for an intentional action if and only if it fulfills, or is a means to fulfilling, a current desire of that agent. Thomas Nagel presents an example involving a short-lived desire for eating a persimmon tomorrow. He claims that, contrary to Humeanism, this example is a clear case of irrationality. Furthermore, the Humean cannot simply dismiss all current desires with future objects, because desires of this sort are crucial (...) to the Humean account of prudence. I respond that, correctly understood, Humeanism can simultaneously account for prudent conduct and other conduct motivated by present desires with future objects. (shrink)
