Quotation

“The phantasied onslaughts on the mother follow two main lines: one is the predominantly oral impulse to suck dry, bite up, scoop out and rob the mother’s body of its good contents . . . . The other line of attack derives from the anal and urethral impulses and implies expelling dangerous substances (excrements) out of the self and into the mother. Together with these harmful excrements, expelled in hatred, split-off parts of the ego are also projected on to the mother or, as I would rather call it, into the mother. These excrements and bad parts of the self are meant not only to injure but also to control and take possession of the object. In so far as the mother comes to contain the bad parts of the self, she is not felt to be a separate individual but is felt to be a separate individual but is felt to be the bad self.

       Much of the hatred against parts of the self is now directed towards the mother. This leads to a particular form of identification which establishes the prototype of an aggressive object-relation. I suggest for these processes the term ‘projective identification.’ (Envy 8)”
