Insanity, Psychiatry and Criminal Responsibility is a unique attempt to evaluate the insanity defence from the standpoint of modern psychiatry and neurophysiology. The book's leitmotif is that the modern psychiatric conception of mental illness as a cognitive failing is essential to the development of a sound criterion of exculpatory insanity in the criminal law; but the author is severely critical of the degree of influence exercised by psychiatrists over the disposition and detention of persons acquitted on the grounds of insanity.
