This unique book provides a versatile exploration of the philosophical foundations of the insanity defense. It examines the connections between numerous philosophical-anthropological views and analyses different methods for regulating the criminal responsibility of the mentally ill. Placing its philosophical analysis firmly in the context of science, it draws on the fields of cognitive psychology, evolutionary theory and criminology. In this thought-provoking book, Wojciech Zaluski argues that the way in which we resolve the problem of the criminal responsibility of the mentally ill depends on two factors: the assumed conception of responsibility and the account of mental illness. Offering a systematic and in-depth analysis of the influence of anti-psychiatry on thinking about the insanity defense and legislation, the author invokes the personalist view of human nature, being rational and endowed with free will, to justify an original normative proposal concerning the construction of the insanity defense. The Insanity Defense will be of primary interest to scholars of criminal law and justice, legal theory and legal philosophy as well as legal practitioners, policy makers, psychiatrists and psychologists engaged with this topic.

Law and Evil presents an alternative evolutionary picture of man, focusing on the origins and nature of human evil, and demonstrating its useful application in legal-philosophical analyses. Using this representation of human nature, Wojciech Zaluski analyses the development of law, which he interprets as moving from evolutionary ethics to genuine ethics, as well as arguing in favour of metaethical realism and ius naturale. Zaluski argues that human nature is undoubtedly ambivalent: human beings have been endowed by natural selection with moral, immoral, and neutral tendencies (the first ambivalence), and the moral tendencies themselves are ambivalent (the second ambivalence), giving rise to an inferior form of ethics called 'evolutionary ethics' Introducing a novel distinction between two types of evil, primary and secondary, this book explores the differences between evolutionary ethics and genuine ethics in order to analyse the history of legal systems and the controversy between natural law and legal positivism. Engaging and thought-provoking, this insightful book will be vital reading for both legal scholars and philosophers, especially those of law and moral philosophy. Evolutionary biologists with an interest in a philosophical interpretation of the results of evolutionary biology will also find this book an important read.

This unique book presents various ways in which evolutionary theory can contribute to the analysis of key legal-philosophical problems. Wojciech Zaluski explores three central questions; the ontological question - what is the nature of law?; the teleological-axiological question - what are the main values to be realized by law?; the normativity question, which has two aspects; normative: what explains the fact that legal norms provide reasons for action?, and motivational: what explains the fact that humans can be motivated by legal norms? It is argued that evolutionary theory suggests non-trivial answers to these questions, and that these answers can become the building blocks of a new - evolutionary - paradigm in legal philosophy. Being the first study entirely devoted to the analysis of fundamental legal-philosophical problems from the standpoint of evolutionary theory, this book is a must-read for graduate and postgraduate students, practitioners and philosophers in the field of legal philosophy.
