 Jaggar argues against separatism or separate gendered realities, noting that there is no reason “to believe in a sexual polarity which transcends the physiological distinction” (Jaggar 1974, 283). The work of psychologist Carol Gilligan therefore has great influence on philosophers interested in just such evidence for substantial sex differences in moral reasoning, despite the fact that Gilligan herself does not describe these differences as polar. In her landmark work, In a Different Voice: Psychological Theory and Women’s Development (1982), Gilligan disputes accounts of moral development that do not take into account girls’ moral experiences (18–19), or that describe women as stuck at an interpersonal stage short of full moral development as in the theories of Lawrence Kohlberg (30). Gilligan argues that Kohlberg wrongly prioritizes a “morality of rights” and independence from others as better than, rather than merely different from, a “morality of responsibility” and intimate relationships with others (19).
