If one but observes the phenomena of geology and of biology one may see how ready Nature is to quit one form of effort for another, once its uselessness has become apparent, to drop a difficult tendency in one direction and pursue an easier one in another. Indeed, the theory of the pragmatist is seemingly well-emphasized at times by the disappearance of some large and presumably successful species for reasons of difficulty in connection with its sustenance, and the steady rise of some minor creature whose wants are simple and not difficult to satisfy. And it is not necessarily through æons and æons of time that those changes are accomplished but almost instanter, as when behemoth ended and the great auk puffed out. Man says to himself today, “I am the Lord of creation,” but is he? A slight change in the chemistry of our atmosphere, so slight that it might be scarcely noticeable, a change in the odor of the air or the taste of the water, could soon end or debilitate him so as to make him of no import whatsoever. It might be unfavorable to man and favorable, let us say, to cats or spiders; then man, a sleepy stumbling creature, would be devoured by his hungry, pagan house pet and the theory of his domination disposed of. Remote? So was the rise of Christianity. If you do not believe this read history, or note what tragedies a slight trace of sewer gas can produce in your own household, how smoke ends a corps of firemen, how water, too much heat, too much cold, may destroy us all. And what star so humble that if it came near enough could not effect one or another of these changes? Deep below deep lie the mysteries, and theories flourish like weeds in a garden--or let us call them flowers, for at times they are so artistic. Arts spring out of the mysteries, but the arts themselves grow stale if left to themselves. The thing that the individual should remember is that he is a part of this vast restlessness, uncertainty and opportunism. Life will have none of anything forever, neither Egypt nor Greece nor Rome nor England nor America; it will not have anything of one type of god, nor a fixed code of morals, nor a fixed conclusion as to what is art, nor a method of living. We build up rules wherewith life is to be governed, and behold!--some fine day the character of life itself changes and our rules are worthless.
