The great misunderstanding upon which this system of interpretation rests is to hold that it is natural for the human female to make a feminine woman of herself: being a heterosexual or even a mother is not enough to realize this ideal; the “real woman” is an artificial product that civilization produces the way eunuchs were produced in the past; these supposed “instincts” of coquetry or docility are inculcated in her just as phallic pride is for man; he does not always accept his virile vocation; she has good reasons to accept even less docilely the vocation assigned to her.
