Superstition recurs in a rationalist age because it rests on something which, if not identical with rationalism, is not unconnected with scepticism. It is at least very closely connected with agnosticism. It rests on something that is really a very human and intelligible sentiment, like the local invocations of the numen in popular paganism. But it is an agnostic sentiment, for it rests on two feelings: first that we do not really know the laws of the universe; and second that they may be very different to all we call reason.
