Like astrology, then, magic was a science in some respects. First, like the predictions of its sister, it { 184} was partly based on observation--observation frequently rudimentary, superficial, hasty, and erroneous, but nevertheless important. It was an experimental discipline. Among the great number of facts noted by the curiosity of the magicians, there were many that received scientific indorsement later on. The attraction of the magnet for iron was utilized by the thaumaturgi before it was interpreted by the natural philosophers. In the vast compilations that circulated under the venerable names of Zoroaster or Hostanes, many fertile remarks were scattered among puerile ideas and absurd teachings, just as in the Greek treatises on alchemy that have come down to us. The idea that knowledge of the power of certain agents enables one to stimulate the hidden forces of the universe into action and to obtain extraordinary results, inspires the researches of physics to-day, just as it inspired the claims of magic. And if astrology was a perverted astronomy, magic was physics gone astray.
Moreover, and again like astrology, magic was a science, because it started from the fundamental conception that order and law exist in nature, and that the same cause always produces the same effect. An occult ceremony, performed with the same care as an experiment in the chemical laboratory, will always have the expected result. To know the mysterious affinities that connect all things is sufficient to set the mechanism of the universe into motion. But the error of the magicians consisted in establishing a connection between phenomena that do not depend on each other at all. The act of exposing to the light for an instant a sensitive plate in a camera, then immersing it, according to given recipes, in appropriate liquids, and of making { 185} the picture of a relative or friend appear thereon, is a magical operation, but based on real actions and reactions, instead of on arbitrarily assumed sympathies and antipathies. Magic, therefore, was a science groping in the dark, and later became "a bastard sister of science," as Frazer puts it.
But, like astrology, magic was religious in origin, and always remained a bastard sister of religion. Both grew up together in the temples of the barbarian Orient. Their practices were, at first, part of the dubious knowledge of fetichists who claimed to have control over the spirits that peopled nature and animated everything, and who claimed that they communicated with these spirits by means of rites known to themselves alone. Magic has been cleverly defined as "the strategy of animism."[60] But, just as the growing power ascribed by the Chaldeans to the sidereal deities transformed the original astrology, so primitive sorcery assumed a different character when the world of the gods, conceived after the image of man, separated itself more and more from the realm of physical forces and became a realm of its own. This gave the mystic element which always entered the ceremonies, a new precision and development. By means of his charms, talismans, and exorcisms, the magician now communicated with the celestial or infernal "demons" and compelled them to obey him. But these spirits no longer opposed him with the blind resistance of matter animated by an uncertain kind of life; they were active and subtle beings having intelligence and will-power. Sometimes they took revenge for the slavery the magician attempted to impose on them and punished the audacious operator, who feared them, although { 186} invoking their aid. Thus the incantation often assumed the shape of a prayer addressed to a power stronger than man, and magic became a religion. Its rites developed side by side with the canonical liturgies, and frequently encroached on them.[61] The only barrier between them was the vague and constantly shifting borderline that limits the neighboring domains of religion and superstition.
