Abstract

Set in an interpretation of Aristotle, Dahl's book is a philosophical investigation into practical knowledge addressing such issues as whether it exists, what is it and what distinguishes it from other knowledge and belief. As its title indicates this book is divided into two distinct but related parts. The first part argues that Aristotle teaches that practical reason exists, i.e., that reason co-produces motivation for action, and that practical reason can provide an objective foundation for morality. The second part shows that Aristotle's explanation of incontinence allows the incontinent man knowledge of what he ought to do in his present situation and a genuine conflict of motives. Although these two arguments are independent, they are mutually supporting: only because reason can provide some motivation for action can there be incontinence and incontinence presents a strong example of rational motivation.
