perversion

Perversion is a form of human behavior which is far from what is considered to be orthodox or normal. Although the term perversion can refer to a variety of forms of deviation, it is most often used to describe sexual behaviors that are considered particularly abnormal, repulsive or obsessive. Perversion usually differs from "deviant behavior", in that the latter covers areas of behavior (such as petty crime) for which perversion would be too strong a term. It is often considered derogatory, and, in psychological literature, the term paraphilia has been used as a replacement for most forms of sexual perversion, though this clinical term is controversial, and deviation is sometimes used in its place.

==History of concept== One view is that the concept of perversion is subjective, and its application varies depending on the individual. Another view considers that perversion is a degradation of an objectively true morality. Originating in the 1660s, a pervert was originally defined as "one who has forsaken a doctrine or system regarded as true, apostate." The sense of a pervert as a sexual term was derived in 1896, and applied originally to variants of sexualities or sexual behavior believed harmful by the individual or group using the term. There is a transition to the sexual in 'the technique of purposeful perversion' of conversational remarks: "Purposeful perversion of what a woman has said ... is a long step closer to a direct attempt at seduction or rape."
