If, pursuing the same train of thought, we ask what meaning the optimistic evolutionist puts upon the word "good," we shall see that, according to him, the distinction between good and bad is one that applies, and can only apply, to certain moments in the process of evolution, but not to the process as a whole, just as we have already seen that according to the optimistic evolutionist the distinction does not apply to the Unknowable Reality of which the process of evolution is a manifestation. The law of life is laid down to be the struggle for existence, with the consequent survival of the fittest. In the struggle, that is good which is struggled for, viz. existence; and that conduct, in man or brute, is good which conduces to success in the struggle and enables the organism to maintain its existence. This can only be done by the adaptation of the organism to its environment, of the constitution to the conditions. It follows, therefore, that "good" is a purely relative term: it is only applicable with reference to organisms, and even in their case only to success and whatever contributes to success in the struggle for existence. But to the cosmos before the struggle for life begins, and after life and its struggles have relapsed into the insentience of unconscious matter, the term cannot be applied. Matter and motion, which exist before and after life's appearance, are everlasting and indestructible. Their existence is assured, and implies no struggle. They are eternal, organic life compared with them is momentary. The portion, then, of the cosmic process which can be spoken of as good is infinitesimal compared with the whole. Save for the brief moment during which organic life exists, it is as illusory to speak of the cosmic process as good as it is to apply the term to the Unknowable. But if so much of our optimistic interpretation of evolution has proved to be an illusion which consists in the simple fallacy of using the word "good" in connections in which it has no meaning, can we hope to rescue the very small fragment that remains? Perhaps we may argue, that since that is good which conduces to human existence, the whole of the cosmic process up to now, having paved the way and prepared the earth for man, must be good. Thus at one stroke we seem to regain half at least of the territory we have lost. But it is only seeming, once more illusion, for the cosmic process which has prepared the earth for man's existence has also prepared it for his destruction: his good, his existence, and his destruction are equally indifferent to it. This conclusion is confirmed by the reflection that to regard the cosmic process as giving any consideration to man would be to ascribe purpose, consciousness, a knowledge of good and evil, and a preference for good, to the Unknowable of which the cosmic process is the continuous manifestation.
