The revised edition of The Ontological Foundation of Ethics, Politics, and Law adds new concepts and discusses the views of additional thinkers. The author refers to his basic ontological conception of the human ';mind' or ';spirit' as an evolving, conscious, triadic entity composed of intellect, sensitivity, and power, each exerting a bidirectional (selfish and moral) activity. Through this approach, the notions of good, morality, society, and law are derived from the structure and functioning of the mind. It follows that the solutions presented are the results of a discovery and not the consequence of a choice. Otherwise stated, ethics, politics, and law are given an ontological foundation. For each topic considered, Belfiore shows how his thought can reinterpret the views of other philosophers. This new edition, enriched in concepts and quotations, appears as an innovative and highly stimulating contribution to the philosophical branches of ethics, politics, and law, and will be of interest to both graduate students and philosophy scholars.
