Thomas Szasz was an influential writer who opposed involuntary or coercive hospitalization for those deemed “mentally ill,” a label he challenged.
Thomas Szasz is a psychiatrist and author well known for his criticism of the modern psychiatry movement. He has consistently sought to apply classical liberal principles (such as bodily and mental self ownership) to social science and also explored the consequences of mandatory institutionalization of persons the state deemed to be insane. In his book, The Myth of Mental Illness (1960), Szasz claims that psychiatry ultimately robs people of the responsibility of being moral agents by obscuring the difference between socially unacceptable behavior and disease.
One of the best-known writers of the 20th cent., Michel Foucault criticized overreaching authority structures as well as state and social coercion.
Personal freedom and personal responsibility go hand-in-hand. An over-reliance on the government due to the welfare state corrodes both.
Libertarians are skeptical of some approaches to psychiatry especially when it involves government or when patients are coerced into accepting treatment.
