ABSTRACT
Cognitive deliberation is deliberation over whether something is true or false, while practical deliberation is over what to do. Once the choice set has been established, the process of deliberation begins in earnest. This chapter distinguishes the exact difference between deliberation reasons and explanation reasons. As long as the deliberator believed that each alternative in the choice set was realizable, deliberation could proceed as usual, the eventual decision being taken in favor of the one option that was in fact open. The chapter provides listing the three essential components of a deliberation. These are, in strict temporal order, choice set formation, evaluation, and decision. Each element of the deliberative process is subject to rational norms by which it may be judged, a common but non-mandatory norm of decision, choice or decision, being the existence of an explanation reason for the choice once it is made.
