Upon this assumption, the question really resolves itself into a different one. We can neither explain nor justify the existence of pain; but, of course, we can ask whether, as a matter of fact, pain predominates over pleasure; and we can ask whether, as a matter of fact, the "cosmic processes" tend to promote or discourage virtuous conduct. Does the theory of the "struggle for existence" throw any new light upon the general problem? I am quite unable to see, for my own part, that it really makes any difference: evil exists; and the question whether evil predominates over good, can only, I should say, be decided by an appeal to experience. One source of evil is the conflict of interests. Every beast preys upon others; and man, according to the old saying, is a wolf to man. All that the Darwinian or any other theory can do is, to enable us to trace the consequences of this fact in certain directions; but it neither creates the fact nor makes it more or less an essential part of the process. It "explains" certain phenomena, in the sense of showing their connection with previous phenomena, but does not show why the phenomena should present themselves at all. If we indulge our minds in purely fanciful constructions, we may regard the actual system as good or bad, just as we choose to imagine for its alternative a better or a worse system. If everybody had been put into a world where there was no pain, or where each man could get all he wanted without interfering with his neighbours, we may fancy that things would have been pleasanter. If the struggle, which we all know to exist, had no effect in preventing the "survival of the fittest," things--so, at least, some of us may think--would have been worse. But such fancies have nothing to do with scientific inquiries. We have to take things as they are and make the best of them.
