Abstract

Inference, understood as a form of conscious and active belief-revision, has recently attracted much interest among philosophers of mind. Many writings on the topic depict inference as a kind of process. However, this assumption is, to my knowledge, nowhere explicitly justified or even reflected upon. In this paper, I argue that the assumption is wrong: while processes take time, it is not possible that inferences take time. Both claims are conceptual observations. It is therefore conceptually impossible that the mental act of inferring is a process.
