really the clandestine exercise of prescribed forms of faith. The old saying, "The sin of witchcraft is as the sin of rebellion," has more in it than meets the eye. There is little real difference between the magic that appears as piety and the magic that is denounced as sorcery, except that one is permitted and the other is not. And it is almost a law of religious development that the gods of one religion become the demons of its successor. But while witchcraft has existed in all ages, it existed in a much milder form than that which we find in the sixteenth and seventeenth centuries. First of all, there is the fact to which attention has already been directed, namely, the concentration of the public mind upon various forms of supernaturalism. Every aspect of life was more or less under the direct influence of the Church, and no teaching was tolerated that conflicted with her doctrines. And it was to the interest of the Church perpetually to emphasise the reality of either angelic or diabolic activity. Even in the case of those who showed a tendency to revolt against Church rule there was no exception to this. If anything, the belief was more pronounced. Next, the fifteenth and sixteenth centuries saw a rising tide of heresy against which the Church was compelled to battle; and to ascribe this alleged perversion of Christian doctrines to the malevolence of Satan offered the line of least resistance--just as the heretics attributed the power of the Church itself to the same source. Whatever diminution ensued in the general flood of superstition, as a consequence of the quarrel between Protestant and Catholic, was, so far as the disputants were concerned, incidental and even undesired. On the one point of demonism there existed complete unanimity, and the sceptic fared equally hard with both parties. In such an environment the wildest tales of sorcery became credible; and nothing illustrates this more forcibly than the fact that many of those tortured and condemned for sorcery actually believed themselves capable of performing the marvels laid to their charge. Added to these factors, we have to note that social conditions were also extremely favourable. Moral ties were as loose as they could reasonably be; and the attitude of the Church towards the sexual relation had forced both the religious and the non-religious mind into wholly unhealthy channels. This last aspect of the subject has been little dealt with, but it is unquestionably a very real one. A German writer says:--
