How We Became Human: A Challenge to Psychoanalysis tackles the question of what distinguishes human beings from other animals. By interweaving psychoanalysis, biology, physics, anthropology, and philosophy, Julio Moreno advances a novel thesis: human beings are faulty animals in their understanding of the world around them. From this perspective, Moreno seeks to reformulate many of the classic psychoanalytic, psychological, and anthropological postulates on childhood, links, and psychic change.
