"In my Future of an Illusion (1927) I was concerned much less with the deepest sources of religious feeling than with what the common man understands by his religion- with the system of doctrines and promises which on the one hand explains to him the riddles of the world with enviable completeness, and, on the other, assures him that a careful Providence will watch over his life and will compensate him in a future existence for any frustrations he suffers here. The common man cannot imagine this Providence otherwise than in the figure of an enormously exalted father. Only such a being can understand the needs of the children of men and be softened by their prayers and placated by the signs of their remorse. The whole thing is so patently infantile, so foreign to reality, that to anyone with a friendly attitude to humanity it is painful to think that the great majority of mortals will never be able to rise above this view of life. It is still more humiliating to discover how large a number of people living today, who cannot but see that this religion is not tenable, nevertheless try to defend it piece by piece in a series of pitiful rearguard actions."
Sigmund Freud, Society and its Discontents, 1930
