Sigmund Freud is the father of psychoanalysis, a clinical method of treatment through dialogue. Modern thought owes him his theoretical description of the structure and functioning of the unconscious, through the discovery of the essential role of transference in the analytic process, the redefinition of sexuality including its infantile forms, the analysis of dreams, symptom formation and the mechanisms of repression. His ideas are still controversial, but his work has suffused the whole of Western thought. The idea of an ego who is not master in its own house shattered intellectual foundations, and its legacy is everywhere in our everyday life. We have selected for you 100 of the most interesting quotes by the first psychoanalyst; they will help you gain a better understanding of his thinking, his work, and your own mysterious depths.
