If I am recalling an incident very vividly I go back to the instant of its occurrence; I become absent minded, as you say. I jump back for a moment. Of course we have no means of staying back for any length of time any more than a savage or an animal has of staying six feet above the ground. But a civilized man is better off than the savage in this respect. He can go up against gravitation in a balloon, and why should we not hope that ultimately he may be able to stop or accelerate his drift along the Time Dimension; or even to turn about and travel the other way?
H. G. WellsBut there are times when the little cloud spreads, until it obscures the sky. And those times I look around at my fellow men and I am reminded of some likeness of the beast-people, and I feel as though the animal is surging up in them. And I know they are neither wholly animal nor holy man, but an unstable combination of both.
