In this book, Mahmoud Khatami approaches morality and the relevant issues, and provides outline of his moral philosophy which concerns with the free acts of the will. The book is divided into two parts. The first part treats of the moral act in general and investigates the conditions under which it will conform to right order. The second part considers the duties of man, and takes into consideration the various particular conditions relating to different moral acts, and the variety of situations in which the moral agent may, and naturally does, find himself placed. This book should be useful to professionals in moral philosophy, and those who are concerned with moral issues.
