"First published in 1976, this is a comprehensive study of practical thinking. Professor Körner shows the complex relations which a person's practical attitudes bear to each other, and shows in particular how their moral or prudential character depends not only on their content and form but also on their place in the system constituted by them. There are detailed accounts of the concepts of morality, prudence, justice, welfare and legality, as well as the logical foundations, epistemology and metaphysics of practical thinking. The book is intended for philosophers and for those political theorists and social scientists who are concerned with the philosophical presuppositions and implications of their enquiries. The book is deliberately organized so that those with less interest in the logical issues dealt with in Part I can proceed quickly and easily to the more substantive issues in Parts II and III"--Publisher description.
