"In reality the Moon is only the satellite of the Earth in one respect, viz., that physically the Moon revolves round the Earth. . . . Startling as the statement may seem it is not without confirmation from scientific knowledge. It is evidenced by the tides, by the cyclic changes in many forms of disease which coincide with the lunar phases; it can be traced in the growth of plants, and is very marked in the phenomena of human gestation and conception. The importance of the Moon and its influence on the Earth were recognized in every ancient religion, notably the Jewish, and have been remarked by many observers of psychic and physical phenomena. But, so far as Science knows, the Earth's action on the Moon is confined to the physical attraction, which causes her to circle in her orbit. And should an objector insist that this fact alone is sufficient evidence that the Moon is truly the Earth's satellite or other planes of action, one may reply by asking whether a mother, who walks round and round by her child's cradle keeping watch over the infant, is subordinate of her child or dependent upon it; though in one sense she is its satellite, yet she is certainly older and more fully developed than the child she watches."
