This scholarly work was written while the author was in his psychiatry residency. It will be of value to all psychiatrists who are interested in the human condition in all its manifestations: normal, abnormal, historical, philosophical, and political. Reading it takes time because the author argues that "the modern idea of the perverse first emerged in late 18th century France and was shaped largely by the strange confluence of medical writings, patient confessions, and literary narratives," as well as political circumstances. The reader must adapt to terminology used at that time, such as the "solitary vice" and "onanism" (masturbation), "inverts" (homosexuals), "uterine fury" (nymphomania), etc. It is worth the effort to follow the author’s scholarly integration of the literature, medical science, and politics of the eighteenth century, which establishes the historical background for the contemporary attitude of our society to sexuality in all its expressions.
