Sigmund Freud is best known as the father of psychoanalysis. Born in 1856, he was a physiologist, medical doctor and psychologist who spent most of his life in Vienna, Austria. He developed revolutionary ideas about the unconscious mind, repression and the meaning of dreams and the clinical method of treatment through dialogue. Here you will find extracts from his greatest works. The Life Lessons series from The School of Life takes a great thinker and highlights those ideas most relevant to ordinary everyday dilemmas. These books emphasise ways in which wise voices from the past have urgently important and inspiring things to tell us. This book is introduced and edited by Brett Kahr, Senior Clinical Research Fellow in Psychotherapy and Mental Health at the Centre for Child Mental Health in London. He is a qualified psychotherapist and author.
