Abstract
Drawing on the writing of Freud, Klein, Riviere, Winnicott, Bion, and others, this article highlights two rather different war-time and post-war changes occurring in psychoanalysis regarding ambivalence: first, the shift of psychoanalytic attention from the repressed unconscious to introjection and projection of love and hate and their effects on objects in our inner world; second, the contrary shift of psychoanalysis from attention to the individual pleasure and pain of love and hate to mothering, and to intersubjective knowing and truth.
