Psychopathia sexualis: With especial reference to contrary sexual instinct A medico-legal study

** "Psychopathia Sexualis: With Especial Reference to Contrary Sexual Instinct" by R. von Krafft-Ebing is a late 1800s study of the science and the law connected to human sexuality, mostly focusing on unusual expressions of sexuality. The book seeks to scientifically define different sexual behaviors, recognizing how they affect people and society. The author starts by explaining that the power of sexual urges deeply shapes behavior, connecting sex to ethics, art, and feelings. He points out that there has not been enough scientific conversation about sex, arguing that previous philosophical thinking isn't enough, and says sex needs to be explored from a doctor's point of view. The writing is geared for medical and legal professionals to understand sex crimes. **
