Luce Irigaray said this quote
“ The human in what it is objectively ever since its beginning is two, two who are different. Each part of what constitutes the unity of the human species corresponds to a proper being and a proper Being, to an identity of one's own. In order to carry out the destiny of humanity, the man-human and the woman-human each have to fulfill what they are and at the same time realize the unity that they constitute. ”
