Thomas Szasz is a theorist and psychiatrist. That is my understanding.
He states the psychiatry is the _medicalization_ of social, moral, and political problems, if my memory does not betray me.
He does not deny that personal distress is something that people should deal with and should be dealt with. However, distress is caused by problems of living. That is, there are usually causes to distress that are real. These causes should be taken care of. That is what I remember.
