Outline of a Theory of Reasonable Deliberation

Extract

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.
