I am not one of those who find in phallicism the key to all the mysteries of mythology. All the striking phenomena of nature-the alternations of light and darkness, sun and moon, the terrors of the thunderstorm, and of pain, disease and death, together with his own dreams and imaginations-contributed to evoke the wonder and superstition of early man. But investigation of early religion shows it often nucleated around the phenomena of generation. The first and final problem of religion concerns the production of things. Man's own body was always nearer to him than sun, moon, and stars; and early man, thinking not in words but in things, had to express the very idea of creation or production in terms of his own body. It was so in Egypt, where the symbol, from being the sign of production, became also the sign of life, and of regeneration and resurrection. It was so in Babylonia and Assyria, as in ancient Greece and Troy, and is so till this day in India.
