Sigmund Freud

Sigmund Freud rates, along with figures such as Marx and Darwin, as one of the most influential and significant thinkers of the past 150 years. The founder of psychoanalysis, his work on the relationship between the individual and society, the inner workings of the subconscious, and infant sexuality and development shaped almost every branch of the humanities and social sciences throughout the twentieth century. From his writings on dreams to his distinction between ego, superego and id, his ideas influenced intellectual movements and works ranging from the Freudian Marxism of the Frankfurt school to the novels of Thomas Mann and D.H. Lawrence: his importance can hardly be overstated. In 2014 Polity published the correspondence between Sigmund Freud and Anna Freud, his youngest daughter who went on to become an influential psychoanalyst in her own right.
