Abstract

What does it mean to call something a “reason”? This paper offers a unifying semantics for the word ‘reason’, challenging three ideas that are popular in contemporary philosophy; (i) that ‘reason’ is semantically ambiguous, (ii) that the concept of a normative reason is the basic normative concept, and (iii) that basic normative concepts are unanalyzable. Nonnormative uses of ‘reason’ are taken as basic, and as meaning explanation why. Talk about normative reasons for action is analyzed in terms of explanations why acting would be good in some way. I show how a number of obstacles for this idea—including extending the analysis to normative reasons for attitudes—can be overcome by adopting a reductive, end-relational analysis of the meaning of ‘good’ which I have defended elsewhere. Finally, I analyze talk of “motivating” reasons in terms of (supposed) normative reasons for which agents act.
