“ The abject impulse is inalienably connected with the feminine, specifically the maternal. As it forms out of the undefined morass of relations, surfaces and currents that existed before the Oedipal or mirror-stage coordinated them, the subject seems built around a primal sense of loss. The developing sense of the limits of the body is focussed on those holes in it's surface through which the outside becomes inside and vice versa: the mouth, anus, genitals, even the invisibly porous surface of the skin. It was the mother's body that was most connected with these crossing-points, as it fed and cleaned the undefined infant body. The sense that boundaries and limits are forming around this permable flesh is interpreted then as the withdrawal or even loss, of intimacy with the body of the mother, firstly in the increasing distance of the practical hygiene operations it performs and secondly, more remotely, beyond that in it's archaic ur-form as the body through which the child entered into the world. ”
