A critical exposition of Reid’s philosophical anatomy of the self, his moral philosophy and his aesthetics, this text is aimed at an advanced undergraduate and graduate readership. One main purpose of the book is to explore Reid’s accounts of beauty, of sublimity and aesthetic assessment, compared with his moral philosophy and philosophy of action, if only because of the very considerable impact of his aesthetic thought in 19th-century France. Notoriously Reid presents his accounts of moral and aesthetic judgment as the fruits of a sense of morals and of taste. Accordingly his position on the nature of a sense needs to be carefully considered, as well as his position on the origin of conceptions needed for the deployment of a sense. The Lehrer-Smith III computational computer model of Reidian faculties is assessed at some length as a serious contribution to this task, especially since its employment would seem to presuppose positions at odds with crucial components in Reid’s account of the self as thinker, decision-maker and moral agent exercising both active and speculative power.
