Religion is still useful among the herd - that it helps their orderly conduct as nothing else could. The crude human animal is in-eradicably superstitious, and there is every biological reason why they should be. Take away his Christian god and saints, and he will worship something else.
The similarities among animals that are on the surface very different are no coincidence. In fact, animal locomotion is no different than other flows, animate and inanimate they all develop in space and in time such that they optimize the flow of material.
A critic recently described me, with deadly acuteness, as having 'a kindly dislike of my fellow-creatures.' Perhaps dread would have been nearer the mark than dislike; for man is the only animal of which I am thoroughly and cravenly afraid.
