This doctrine of demonology, it should be remembered, was but the elaborated form of ancestral belief in spirits referred to above. In the Christian system it was associated with that belief in magic which has its roots in fetishism, and from the two arose belief in witchcraft. The universal belief in demons in early and mediæval times supplied an easy explanation of disasters and diseases; the sorcerers and charm-workers, the wizards and enchanters, had passed into the service of the devil. For power to work their spite and malevolence they had bartered their souls to him, and sealed the bargain with their blood. It was enough for the ignorant and frightened sufferers to accuse some poor, misshapen, squinting old woman of casting on them the evil eye, or of appearing in the form of a cat, to secure her trial by torture and her condemnation to an unpitied death. The spread of popular terror led to the issue of Papal bulls and to the passing of statutes in England and in other countries against witchcraft, and it was not until late in the eighteenth century that the laws against that imaginary crime were repealed.
There is no sadder chapter in the annals of this tearful world than this ghastly story of witch-finding and witch-burning. Sprenger computes that during the Christian epoch no less than _nine millions_ of persons, mostly women of the poorer classes, were burned; victims of the survival into relatively civilised times of an illusion which had its source in primitive thought. It was an illusion which had the authority of Scripture on its side;[30] the Church had no hesitation concerning it; such men as Luther, Sir Thomas Browne, and Wesley never doubted it; the evidence of the bewitched was supported by honest witnesses; and judges disposed to mercy and humanity had no qualms in passing the dread sentence of the law on the condemned.[31]
And although it exists not to-day, save in by-places where gross darkness lurks, it was not destroyed by argument, by disproof, by direct assault, but only through the quiet growth and diffusion of the scientific spirit, before which it has dispersed. It could not live in an atmosphere thus purified, an atmosphere charged with belief in unchanging causation and in a definite order unbroken by caprice or fitfulness, whether in the sweep of a planet or the pulsations of a human heart.
