The Myth of Mental Illness

Psychiatry and Human Conduct

Psychiatry is usually presented as a branch of medicine that treats diseases of the mind. Thomas Szasz argues that this description is misleading. In ordinary medicine, disease means a physical problem in the body, something that can be observed in tissue, organs, or bodily processes. What psychiatry usually deals with, he says, is not that kind of disease, but human behavior, conflict, suffering, and troubled relationships.

This changes the whole picture. If a person has pneumonia or a broken bone, the doctor is dealing with a bodily condition. But when a person is frightened, confused, rebellious, despairing, or unable to manage life, the issue is different. These are matters of meaning, choice, conduct, and social life. Szasz insists that calling them illnesses gives them a medical appearance they do not truly have.

He is especially critical of the habit of turning every difficult form of behavior into a disease category. Once that happens, the person is no longer seen mainly as an agent making choices, but as a victim of an inner defect. That shift may sound compassionate, but it also removes responsibility and hides the moral and social nature of the problem. It makes questions about how to live seem like technical medical questions.

From this view, psychiatry has more in common with ethics, language, and human relationships than with laboratory medicine. Psychiatrists mostly listen, speak, interpret, and judge. They are not repairing damaged tissue in the way a surgeon or internist does. What they actually work with are signs, stories, motives, roles, and rules.

Szasz also rejects the idea that human conduct can be explained in the same mechanical way as physical events. Past experiences matter, but they do not force behavior in the way a chemical reaction forces an outcome. People act within histories and pressures, yet they also choose, resist, adapt, and interpret. For him, any serious understanding of human life has to leave room for freedom and responsibility.

That is why he wants psychiatry to be seen as the study of personal conduct rather than the treatment of mental disease. The important questions become: What is this person doing, what rules are they following, what are they trying to achieve, and how are they communicating with others? Seen this way, many psychiatric problems stop looking like hidden illnesses and start looking like troubled ways of living.
