" All human life on the planet is born of woman. The one unifying, incontrovertible experience shared by all women and men is that months-long period we spent unfolding inside a woman’s body. Because young humans remain dependent upon nurture for a much longer period than other mammals, and because of the division of labor long established in human groups, where women not only bear and suckle but are assigned almost total responsibility for children, most of us first know both love and disappointment, power and tenderness, in the person of a woman.
