In his work on the history of prostitution, Wolfgang Sorge aims to establish the significance of prostitution in the psychology of human love life, uncover the foundations in the sexual sensations of men and women that give rise to prostitution, and outline the importance that prostitution has held in human existence. Sorge approaches the topic from a psychological-historical perspective, thereby distancing himself from a purely historical or purely medical representation of the subject, which makes his work a pioneering effort in this field. This is a reprint of the original edition from 1919.
