"The Future of an Illusion" reveals Freud's reflections about religion as well as his hope that in the future science will go beyond religion, and reason will replace faith in God. The discussion with an imaginary critic revealed his internal debate, mirroring the debate about this subject in the outside world. However, it also enlightens his way of thinking: deconstructing and constructing at the same time. This volume considers Freudian ideas and their implications today, while focusing on the contradictions and gaps in Freud's proposals. The question of the coexistence between religion and psychoanalysis, as well as the place of ideals, belief, illusion, and imagination - and, no less important, the benevolent and destructive aspects of religion - also come into play.
