However much his work has been reviled or contested, Sigmund Freud remains one of the most significant thinkers of the last 150 years. He founded psychoanalysis, and his vision of human behaviour and the unconscious mind has provided a compelling paradigm for understanding society for much of the twentieth century. In this gripping new account, Matt ffytche draws on the latest research into Freud's impact and historical context, making the case for his continuing relevance in analysing the vagaries, resistances and desires of the human mind. Engaging and accessible, Sigmund Freud appeals to both students and the general reader, as well as anyone engaged with mental health, dreams and the hidden depths of human experience.
