  In Powers of Horror: An Essay on Abjection, the abject is described as neither inside nor outside, neither subject nor object, neither self nor other, troubling identity and order with the instability of boundaries, borders, and limits. Kristeva offers the examples of bodily fluids, sweat, blood, pus, milk, as non-objects that are banished in the course of ego-formation. These non-objects also include the mother's body; indeed the maternal body is a privileged site of abjection, as it is that which must be excluded in order for individuation and separation to take place, so that one can distinguish self from other and establish a dyadic (imaginary) relation out of undifferentiated maternal space or the semiotic chora, the pre-spatial relation of fluid (although not entirely unregulated) drives. The abject can then also be called the primally repressed, primal because prior not only to the secondary symbolic prohibition of the incest taboo or Oedipal Complex, but also prior to the establishment of any identity.
