The Essence of Response-Dependence

Many philosophers have thought that colours or flavours or values are in some way less objective than shape or mass or motion. This paper explores the approach to capturing this thought that is based on the idea of ‘ response-dependence ’. First, it is argued that the conceptions of response-dependence developed by Mark Johnston, Philip Pettit and Crispin Wright fail to capture this thought adequately. Then, the rest of the paper proposes an alternative conception, based in part on Kit Fine's notion of " essence ", which looks more likely to succeed in capturing the thought adequately
