Carol Gilligan was a feminist theorist who objected to Lawrence Kohlberg's sole focus on the sexist preference of the male moral point of view over the female moral point of view. She also objected to the sole focus his research had on privileged white males.
Kohlberg's sexist views emerged in his stage theory of moral development. This theory regarded the supposedly male point of view, which emphasized rules and rights for individuals, as a higher stage than the supposedly female point of view, which emphasized development with respect to care and its effect on human relationships. Gilligan published her criticisms of Kohlberg in a 1982 book titled "In a Different Voice: Psychological Theory and Women's Development." As a result of her work, Gilligan is seen as the originator of the field known as "difference feminism."
