So long as men denounce each other as mentally sick (homosexual, addicted, insane, and so forth)—so that the madman can always be considered the Othe… - Thomas Szasz

Although both the natural and moral sciences seek to understand the objects of their observation, in natural science the purpose of this is to be able to control them better, whereas in moral science it is, or ought to be, to be better able to leave them alone. The morally proper aim of psychology, then, is self-control.

I became interested in writing this book approximately ten years ago when, having become established as a psychiatrist, I became increasingly impressed by the vague, capricious and generally unsatisfactory character of the widely used concept of mental illness and its corollaries, diagnosis, prognosis and treatment. Although (mental illness) might have been a useful concept in the nineteenth century, today it is scientifically worthless and socially harmful. In non-psychiatric circles mental illness all too often is considered to be whatever psychiatrists say it is. The answer to the question, Who is mentally ill? thus becomes: Those who are confined in mental hospitals or who consult psychiatrists in their private offices.

The stupid neither forgive nor forget; the naïve forgive and forget; the wise forgive but do not forget.
