Now, it is evident that the degree of improbability we attach to histories of witches, will depend, in a great measure, upon our doctrine concerning evil spirits, and upon the degree in which that doctrine is realised. If men believe that invisible beings, of superhuman power, restless activity, and intense malignity, are perpetually haunting the world, and directing all their energies to the temptation and the persecution of mankind; if they believe that, in past ages, these spirits have actually governed the bodily functions of men, worked miracles, and foretold future events,—if all this its believed, not with the dull and languid assent of custom, but with an intensely realised, living, and operative as surance; if it presents itself to the mind and imagination as a vivid truth, exercising that influence over the reason, and occupying that prominence in the thoughts of men, which its importance would demand, the antecedent improbability of witchcraft would appear far less than if this doctrine was rejected or was unrealised. When, therefore, we find a growing disposition to reject every history which involves diabolical intervention as intrinsically absurd, independently of any examination of the evidence on which it rests, we may infer from this fact the declining realisation of the doctrine of evil spirits.
These two considerations will serve, I think, to explain the history of witchcraft, and also to show its great significance and importance as an index of the course of civilisation. To follow out the subject into details would require a far greater space than I can assign to it, but I hope to be able to show, sufficiently, what have been the leading phases through which the belief has passed.
In the ruder forms of savage life, we find the belief in witchcraft universal,12 and accompanied, in most instances,’ by features of peculiar atrocity. The reason of this is obvious. Terror is everywhere the beginning of religion. The phenomena which impress themselves most forcibly on the mind of the savage are not those which enter manifestly into the sequence of natural laws and which are productive of most beneficial effects, but those which are disastrous and apparently abnormal. Gratitude is less vivid than fear, and the smallest apparent infraction of a natural law produces a deeper impression than the most sublime of its ordinary operations. When, therefore, the more startling and terrible aspects of nature are presented to his mind, when the more deadly forms of disease or natural convulsion desolate his land, the savage derives from these things an intensely realised perception of diabolical presence. In the darkness of the night; amid the yawning chasms and the wild echoes of the mountain gorge; under the blaze of the comet, or the solemn gloom of the eclipse; when famine has blasted the land; when the earthquake and the pestilence have slaughtered their thousands; in every form of disease which refracts and distorts the reason; in all that is strange, portentous, and deadly, he feels and cowers before the supernatural. Completely exposed to all the influences of nature, and completely ignorant of the chain of sequence that unites its various parts, he lives in continual dread of what he deems the direct and isolated acts of evil spirits. Feeling them continually near him, he will naturally endeavour to enter into communion with them. He will strive to propitiate them with gifts. If some great calamity has fallen upon him, or if some vengeful passion has mastered his reason, he will attempt to invest himself with their authority; and his excited imagination will soon persuade him that he has succeeded in his desire. If his abilities and his ambition place him above the common level, he will find in this belief the most ready path to power. By professing to hold communion with and to control supernatural beings, he can exercise an almost boundless influence over those about him and, among men who are intensely predisposed to believe in the supernatural, a very little dexterity or acquaintance with natural laws will support his pretensions. By converting the terror which some great calamity has produced into anger against an alleged sorcerer, he can at the same time take a signal vengeance upon those who have offended him, and increase the sense of his own importance. Those whose habits, or appearance, or knowledge, separate them from the multitude, will be naturally suspected of communicating with evil spirits; and this suspicion will soon become a certainty, if any mental disease should aggravate their peculiarities. In this manner the influences of ignorance, imagination, and imposture will blend and coöperate in creating a belief in witchcraft, and in exciting a hatred against those who are suspected of its practice, commensurate with the terror they inspire.
In a more advanced stage of civilisation, the fear of witches will naturally fade, as the habits of artificial life remove men from those influences which act upon the imagination, and as increasing knowledge explains some of the more alarming phenomena of nature. The belief, however, that it is possible, by supernatural agency, to inflict evil upon mankind, was general in ancient Greece and Rome; and St. Augustine assures us that all the sects of philosophers admitted it, with the exception of the Epicureans, who denied the existence of evil spirits. The Decemvirs passed a law condemning magicians to death. A similar law was early enacted in Greece; and, in the days of Demosthenes, a sorceress named Lemia was actually executed.’13 The philosophy of Plato, by greatly aggrandising the sphere of the spiritual, did much to foster the belief; and we find that whenever, either before or after the Christian era, that philosophy has been in the ascendant, it has been accompanied by a tendency to magic. Besides this, the ancient civilisations were never directed earnestly to the investigation of natural phenomena; and the progress made it, this respect was, in consequence, very small. On the whole however, the persecution seems to have been, in those countries, almost entirely free from religious fanaticism. The magician was punished because he injured man, and not because he offended God.
In one respect, during the later period of Pagan Rome, the laws against magic seem to have revived, and to have taken a somewhat different form, without, however, representing any phase of a religious movement, but simply a political requirement. Under the head of magic were comprised some astrological and other methods of foretelling the future; and it was found that these practices had a strong tendency to foster conspiracies against the emperors. The soothsayer often assured persons that they were destired to assume the purple, and in that way stimulated them to rebellion. By casting the horoscope of the reigning emprror, he had ascertained, according to the popular belief, the period in which the government might be assailed with most prospect of success; and had thus proved a constant cause of agitation. Some of the forms of magic had, also, been lately imported into the empire from Greece; and were therefore repugnant to the conservative spirit that was dominant. Several of the emperors, in consequence, passed edicts against the magicians, which were executed with considerable though somewhat spasmodic energy.14 But although magicians were occasionally persecuted, it is not to be inferred from this that everything that was comprised under the name of magic was considered morally wrong. On the contrary, many of the systems of divination formed in integral part of religion. Some of the more public modes of foretelling the future, such as the oracles of the gods, were still retained and honoured; and a law, which made divination concerning the future of the emperor high treason, shows clearly the spirit in which the others were suppressed. The emperors desired to monopolise the knowledge of the future, and consequently drew many astrologers to their courts, while they banished them from other parts of the kingdom.15 They were so far from attaching the idea of sacrilege to practices which enabled them to foretell coming events, that Marcus Aurclius and Julian, who were both passionately attached to their religion, and who were among the best men who have ever sat upon a throne, were among the most ardent of
