Moreover, magi or magicians deal with the inhuman, the obscene and the abominable. Osthanes, and even the philosopher Democritus, are led by their devotion to magic into propounding such remedies as drinking human blood or utilizing in magic compounds or ceremonies portions of the corpses of men violently slain.[73] Magic is a malicious and criminal art. Its devotees attempt the transfer of disease from one person to another or the exercise of baleful sorcery.[74] “It cannot be sufficiently estimated how great a debt is due the Romans who did away with those monstrous rites in which to slay a man was most pious; nay more, to eat men most wholesome.”[75] In fine, we may rest persuaded that magic is “execrable, ineffectual and inane.” Yet it possesses some shadow of truth, but is of avail through “veneficas artes ... non magicas,”[76] whatever that distinction may be. III. _Illustrations of Pliny’s fundamental belief in magic._—Pliny, we have seen, made a bold pretense of utter disbelief in magic, and also censured the art on grounds of decency, morality and humanity. Yet despite this wholesale condemnation, in some places in his work it is difficult to tell where his quotations from magicians cease and where statements which he accepts recommence. Sometimes he explicitly quoted theories or facts from the writings of the “magi” without censure and without any expression of disbelief. If it is contended that he none the less regarded them as false and worthless, we may fairly ask, why then did he give them such a prominent place in his encyclopedia? Surely we must conclude either that he really had a liking for them himself and more than half believed them, or that previous works on nature were so full of such material and his own age so interested in such data that he could not but include much of this lore. Probably both alternatives are true. Finally, many things which Pliny states without any reference to the magi seem as false and absurd as the far-fetched assertions which he attributes to them and for which he shows so much scorn. Indeed, it hardly seems paradoxical to say that he hated the magi but liked their doctrines.
