It would seem, therefore, that the three human impulses embodied in religion are fear, conceit, and hatred. The purpose of religion, one may say, is to give an air of respectability to these passions, provided they run in certain channels. It is because these passions make, on the whole, for human misery that religion is a force for evil, since it permits men to indulge these passions without restraint, where but for its sanction they might, at least to a certain degree, control them.
