(pg. 7)  So destructive is human nature, he claims, that "it is only through the influence of individuals who can set an example and whom masses recognize as their leaders that they can be induced to perform the work and undergo the renunciations on which the existence of civilization depends." (pg. 8) All this sets a terribly hostile society that could implode if it were not for civilizing forces and developing government. Freud elaborates further on the development of religion, as the emphasis on acquisition of wealth and the satisfaction of instinctual drives (sex, wealth, glory, happiness, immortality) moves from "the material to the mental." As compensation for good behaviors, religion promises a reward. In Freud's view, religion is an outshoot of the Oedipus complex, and represents man's helplessness in the world, having to face the ultimate fate of death, the struggle of civilization, and the forces of nature. He views God as a manifestation of a childlike "longing for [a] father." (pg. 18)  Freud's description of religious belief as a form of illusion is based on the idea that it is derived from human wishes with no basis in reality. He says, "Thus we call a belief an illusion when a wish-fulfillment is a prominent factor in its motivation, and in doing so we disregard its relations to reality, just as the illusion itself sets no store by verification." In Freud's words "The gods retain the threefold task: they must exorcise the terrors of nature, they must reconcile men to the cruelty of Fate, particularly as it is shown in death, and they must compensate them for the sufferings and privations which a civilized life in common has imposed on them." (pg. 19)  Freud sent a copy of "The Future of an Illusion" to his friend Romain Rolland. While Rolland generally agreed with Freud's assessment of religion, he questioned whether Freud had discovered the true source of religious sentiment, which he ascribed to an "oceanic" feeling. The psychiatrist Carl Jung, the founder of analytical psychology, wrote that "The Future of an Illusion" "gives the best possible account" of Freud's earlier views, "which move within the confines of the outmoded rationalism and scientific materialism of the late nineteenth century." The critic Harold Bloom calls "The Future of an Illusion" "one of the great failures of religious criticism." Bloom believes that Freud underestimated religion and was therefore unable to criticize it effectively.
