Various theories about the purpose of myth are described briefly, and then the place of myth in modern life is explored. Modern man is found to still create his own myths, and his life is still influenced by mythical prototypes and images. Myths, mythical beliefs, and mythical thinking are discovered in socialist, Communist, and totalitarian thought, in entertainment and science fiction, in the behavior of young radicals, in advertising, in theology and modern folk belief, in sex, and in the workings of a scientific and popular imagination stimulated by the belief in an impending global catastrophe. Examples of myth in these areas are discussed. It is suggested that the United States needs to develop a myth of democracy for its present use. (Author/JK)
