Abstract

We need a moral theory for decision-making with imperfect information; that is, decision-making under what decision theorists call both risk, when we can assign probabilities, and uncertainty, when we cannot. And yet contemporary philosophy has, for the most part, offered a division of labor: ethicists work out what we morally ought to do if we knew all the facts; decision theorists, working quite separately, focus on what we rationally ought to do, given our doubt. In this symposium, we start to bridge that divide—to bring ethicists and decision theorists together, to work out what we morally ought to do when we don’t know all the facts.
