The Normativity of Rationality



This article is an introduction to the recent debate about whether rationality is normative – that is, very roughly, about whether we should have attitudes which fit together in a coherent way. I begin by explaining an initial problem – the ‘detaching problem’– that arises on the assumption that we should have coherent attitudes. I then explain the prominent ‘wide-scope’ solution to this problem, and some of the central objections to it. I end by considering the options that arise if we reject the wide-scope solution.
