Abstract
Does an inclination towards incest exist and why is incest prohibited? There are mainly two points of view: that of Sigmund Freud, the founder of psychoanalysis, and that of Edward Westermarck, a Finnish-British anthropologist. Freud is of the opinion that men have a profound desire for incest, whereas Westermarck presumes an instinctive aversion against it. Nowadays the discussion has received fresh impulse due to a modern interpretation of Westermarck's theory and the controversy over the sexual abuse of children in their families. The author is in favour of the Westermarck theory and tries to explain the prohibition of incest based on a natural inhibition towards incest
