%X ABSTRACT: In this paper, I discuss the relation between logic and rationality. I develop (formally and conceptually) a rational requirement which can respond to the classic objections by Harman (1986). On the one hand, the requirement pays attention to the *relevance* of the premises and the conclusion, which is formally expressed by the notion of weak relative closure. The requirement also takes care of the *complexity* of the inferences. This notion of complexity is formally represented by a partially ordered scale of the difficulty of inferences, which is weaker than the notion of complexity as number of steps.
