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 Załuski 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 Defensewill 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.
