this book is a critical exposition of reids philosophical anatomy of the self, his moral philosophy and his aesthetics, and is aimed at an advanced undergraduate and graduate readership. those familiar with reid scholarship will be only too aware of how little attention has been paid of late to reids accounts of beauty, of sublimity and aesthetic assessment, compared with his moral philosophy and philosophy of action. one main purpose of this book is to help remedy this imbalance, if only because of the very considerable impact of reids aesthetic thought in nineteenth 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 reids account, which is also presented in the book, of the self as thinker, decision-maker and moral agent exercising both active and speculative power.
