Dr. Niall (Jock) McLaren is an Australian psychiatrist who uses philosophical analysis to show that modern psychiatry has no scientific basis. This startling conclusion dovetails neatly with the growing evidence that psychiatric drug treatment is crude and damaging. Needless to say, this message is not popular with mainstream psychiatrists. However, in this book, he shows how the principles of information processing give a formal theory of mind that generates a model of mental disorder as a psychological phenomenon.
