The Psychopathology of Everyday Life, which appeared first in 1901 and was then expanded in a series of subsequent editions, has proved to be one of Freud's most popular works, and one of his most influential during his lifetime. It was here that he proposed that many slips and errors of memory common to the average man in everyday life actually signals unconscious issues that beset the individual, and, if examined, can be extremely revealing.

First published in 1930, Civilization and Its Discontents is one of the most influential works of pioneering psychologist Sigmund Freud. Focusing on the tension between the primitive drives of the individual and the demands of civilization for order and conformity, Freud draws upon his psychoanalytic theories to explain the fundamental structures, conflicts, and consequences of society.

This series of 28 lectures was given by Sigmund Freud (1856-1939), the founder of psychoanalysis, during the First World War and first published in English in 1920. The purpose of this general introduction was to present his work and ideas - as they had matured at that point - to a general public; and even though there was to be considerable development and change over the ensuing years, these talks still offer a valuable and remarkably approachable entry point to his revolutionary concepts.

Karl Marx's philosophical critique of capitalism and his solution of communism directly led to the formation of the communist state in the Soviet Union. Whilst this great venture has now all but completely failed, Marx’s philosophy has proved to be arguably the most influential of the 20th century; the influence of Marxism can be seen in subjects as diverse as the infamous policies of Joseph Stalin to many of the progressive humanitarian reforms of the 20th century. The audiobook is an expert account of Marx’s life and philosophical ideas - entertainingly written and above all easy listening.

Martin Heidegger (1889-1976) is probably the most divisive philosopher of the twentieth century: Viewed by some as a charlatan and by others as a leader and central figure of modern philosophy. Michael Inwood's lucid introduction to Heidegger's thought focuses on his most important work, "Being and Time," and its major themes of existence in the world, inauthenticity, guilt, destiny, truth, and the nature of time.
