 Mill’s primary response to the apologists is to claim that even if the trait is unevenly distributed and functions as a deficit or disqualifier there is nonetheless no evidence of natural inferiority. There is no evidence of natural inferiority, because we cannot be sure that the incapacity is the product of nature, rather than nurture. In particular, because the history of sexual relations has been discriminatory, we cannot rule out the possibility that female incapacity is the product of past discriminatory treatment (275–77, 304–05, 313).
