New Introductory Lectures on Psychoanalysis is a collection of lectures by Sigmund Freud, intended as a supplement to his Introductory Lectures on Psychoanalysis. The lectures outline and clarify many of Freud's main theories about the conscious ego, the erotic and chaotic id and the moralizing societally-imposed superego. Freud also outlines his theory of the dichotomy between eros and thanatos (the life and death-drives, respectively), and his beliefs about female sexuality, characterized by penis-envy.
