Certainly there was much true scientific knowledge in the Roman Empire. There was sane medical theory and practice, there was a great deal of correct information in regard to plants, animals and the stars. Science was in the ascendant; magic was in its latter stages of decay. We flatter ourselves that it has now quite vanished away; then its doctrines were accepted only in part or in weakened form by men of education. Perhaps, though I am far from asserting this, magic played a less prominent part then in science and in philosophy than in the later Middle Ages. Perhaps we may picture to ourselves the minds of men in the twelfth and thirteenth and succeeding centuries as awakening from a long, intellectual torpor during the chaotic and dreary “Dark Ages,” and, eager for knowledge and for mental occupation, but still inexperienced and rather bewildered, as snatching without discrimination at whatever came first to hand of the lore of the past. Thus for a time we might find the most able men of the later age taking on the worst characteristics of the earlier time. But this again is mere speculation. Moreover, we must remember that, if magic was accepted only in part by men of learning in the Roman Empire, there was no thoroughgoing scepticism. We sought in vain for an instance of consistent disbelief. If, too, there was an effort to make the magic, which was accepted, scientific by basing it upon natural laws, as Quintus Cicero, Seneca and Ptolemy tried to do, there was also, besides the definite approval of magical doctrines, often a mystical tone in the science and philosophy of the time. The question of the relative strength of magic and of science in those days must, then, be left unsettled. It is difficult enough to judge even a single individual; to tell, for instance, just how superstitious Cato was. In closing we may, however, sum up very briefly those elements which we selected as combining to give a fairly faithful picture of the belief in magic which then prevailed among educated people. Native superstitions from which science had not yet wholly freed itself; much fantastical and mystical lore from Oriental nations; allegorizing and mysticizing in the interpretation of books—which in Philo went to the length of a belief that all knowledge could be secured by this means; a portrayal of nature which attributed to her many magic properties and caused medicine to be infected with magic ceremony and to be based to some extent on the principle of sympathetic magic; a widespread and often extreme belief in astrology; a speculative philosophy which was often favorable to the doctrines of magic or even advanced some itself; and the system of Neo-Platonism in especial, with which we may associate the view—prevalent long before Plotinus, however—that everything in the universe is in close sympathy with everything else and is a sign of coming events—these were the forces ready at the opening of the Middle Ages to influence the future. -----
