Civilization and its discontents

Civilization and Its Discontents is a book by Sigmund Freud, the founder of psychoanalysis. It was written in 1929 and first published in German in 1930 as Das Unbehagen in der Kultur ("The Uneasiness in Culture"). Exploring what Freud saw as a clash between the desire for individuality and the expectations of society, the book is considered one of Freud's most important and widely read works, and was described in 1989 by historian Peter Gay as one of the most influential and studied books in the field of modern psychology.
