Thomas S. Szasz, M.D. (1920 – 2012) The Medicalization of Everyday Life (2007)

Introduction
...The public's memory is short. Towards the end of nineteenth century, doctors transformed diverse human sexual appetites and practices into a Latin dictionary of diseases. A hundred years later, they transformed many of those diseases – for example, masturbation. pornography, and prostitution – into “sex therapy”.
...Formerly, people felt depressed or were depressed. Now they have depression.
...In short, medicalization is not medicine or science; it is a semantic-social strategy that benefits some persons and harms others.
