First published in 1927, 'The Future of an Illusion' examines the roots of society and religion, written by Sigmund Freud, an Austrian neurologist and the founder of psychoanalysis, a clinical method for evaluating and treating pathologies in the psyche through dialogue between a patient and a psychoanalyst.This is Freud's best-known and most assertive psychoanalytic investigation of religion and is the fruition of a lifelong practice of reflection. Freud uses his understanding of psychology to examine the roots of both civilization and religion. This takes the form of a comprehensive essay, with Freud forming an argument throughout its chapters about the history of religion and the part it should play in society's future.
