Westermarck Effect - Westermarck and Freud

Westermarck and Freud

Freud argued that as children, members of the same family naturally lust for one another (See Oedipus complex), making it necessary for societies to create incest taboos, but Westermarck argued the reverse, that the taboos themselves arise naturally as products of innate attitudes.

Steven Pinker wrote on the subject:

The idea that boys want to sleep with their mothers strikes most men as the silliest thing they have ever heard. Obviously, it did not seem so to Freud, who wrote that as a boy he once had an erotic reaction to watching his mother dressing. But Freud had a wet-nurse, and may not have experienced the early intimacy that would have tipped off his perceptual system that Mrs. Freud was his mother. The Westermarck theory has out-Freuded Freud. —Steven Pinker, How the Mind Works
