These biological data are of extreme importance: they play an all-important role and are an essential element of woman’s situation: we will be referring to them in all further accounts. Because the body is the instrument of our hold on the world, the world appears different to us depending on how it is grasped, which explains why we have studied these data so deeply; they are one of the keys that enable us to understand woman. But we refuse the idea that they form a fixed destiny for her. They do not suffice to constitute the basis for a sexual hierarchy; they do not explain why woman is the Other; they do not condemn her forever to this subjugated role.
