Freud's innovative ideas revolutionized our perception of our identity, forming the foundations of psychoanalysis. In the book «Civilization and Its Discontents», he examines the incompatibility of civilization with individual happiness. He focuses on what he considers to be one of the greatest threats to society: "civilized" sexual morality, asking whether repression undermines our chances of happiness. Sigmund Freud was born in 1856 and died in exile in London in 1939. As an author and doctor, he remains one of the most influential voices of the 20th century.
