In Civilization and its Discontents he considers the incompatibility of civilization and individual happiness. Focusing on what he perceives to be one of society's greatest dangers; 'civilized' sexual morality, he asks, does repression compromise our chances of happiness? Sigmund Freud was born in 1856 and died in exile in London in 1939. As a writer and doctor he remains one of the informing voices of the twentieth century.
