If, from the reading of Ptolemy's Tetrabiblos, we pass on to read a magic papyrus, our first impression is that we have stepped from one end of the intellectual world to the other. Here we find no trace of the systematic order or severe method that distinguish the work of the scholar of Alexandria. Of course, the doctrines of astrology are just as chimerical as those of magic, but they are deduced with an amount of logic, entirely wanting in works of sorcery, that compels reasoning intellects to accept them. Recipes borrowed from medicine and popular superstition, primitive practices rejected or abandoned by the sacerdotal rituals, beliefs repudiated by a progressive moral religion, plagiarisms and forgeries of literary or liturgic texts, incantations in which the gods of all barbarous nations are invoked in unintelligible gibberish, odd and disconcerting ceremonies--all these form a chaos in which the imagination loses itself, a potpourri in which an arbitrary syncretism seems to have attempted to create an inextricable confusion.
However, if we observe more closely how magic operates, we find that it starts out from the same principles and acts along the same line of reasoning { 183} as astrology. Born during the same period in the primitive civilizations of the Orient, both were based on a number of common ideas.[59] Magic, like astrology, proceeded from the principle of universal sympathy, yet it did not consider the relation existing between the stars traversing the heavens, and physical or moral phenomena, but the relation between whatever bodies there are. It started out from the preconceived idea that an obscure but constant relation exists between certain things, certain words, certain persons. This connection was established without hesitation between dead material things and living beings, because the primitive races ascribed a soul and existence similar to those of man, to everything surrounding them. The distinction between the three kingdoms of nature was unknown to them; they were "animists." The life of a person might, therefore, be linked to that of a thing, a tree, or an animal, in such a manner that one died if the other did, and that any damage suffered by one was also sustained by its inseparable associate. Sometimes the relation was founded on clearly intelligible grounds, like a resemblance between the thing and the being, as where, to kill an enemy, one pierced a waxen figure supposed to represent him. Or a contact, even merely passing by, was believed to have created indestructible affinities, for instance where the garments of an absent person were operated upon. Often, also, these imaginary relations were founded on reasons that escape us: like the qualities attributed by astrology to the stars, they may have been derived from old beliefs the memory of which is lost.
