  In the later Three Essays on the Theory of Sexuality (1905), Freud contends, contrary to the earlier supposition that sexuality intervenes from the outside, that sexuality is a primordial and innate (if also inchoate) force of infantile life, arising from the bodily sensations that accompany the life processes. In the interim between these two works, Freud had abandoned the seduction hypothesis and replaced it with the thesis of infantile sexuality and the idea that symptoms are brought about via the conflicts and repressions of unconscious fantasy. In other words, it is no longer repressed memory that makes one ill and traumatic sexual violence no longer figures as the primary cause of symptoms. Instead of an actual past experience, Freud posits fantasy as the determining factor of neurotic symptoms. To understand the significance of this transition in his thinking, we must grasp what Freud means by psychical reality and its distinction from material reality. In contrast to the historical, intersubjective domain of material reality, psychical reality is the vital domain of fantasy and intra-psychic life, operating independently of objective considerations of veracity. In Freud's view, unconscious fantasies are not lies or deceptions, but reveal a truth, not about the objective world, but about the internal life of the subject, who one is and what one wants. It might be better to say that fantasies conceal this truth, since conscious articulations of desire and identity will often lead us astray, expressing but distorting, manifesting but denying, the subject's wishes.
