However, it is not to Schopenhauer and his writings, at least among the English-speaking peoples, that this increasing realization of life as essentially a succession of births, is chiefly ascribed. It is mainly, as I have already suggested, the result of that great expansion of our sense of time and causation that has ensued from the idea of organic Evolution. In the course of one brief century, the human outlook upon the order of the world has been profoundly changed. It is not simply that it has become much more spacious, it is not only that it has opened out from the little history of a few thousand years to a stupendous vista of ages, but, in addition to its expanded dimensions, it has experienced a change in character. That wonderful and continually more elaborate and penetrating analysis of the evolutionary process by Darwin and his followers and successors and antagonists, the entire subordination of the individual lot to the specific destiny that these criticisms and researches have emphasized, has warped and altered the aspect of a thousand human affairs. It has made reasonable and in order what Schopenhauer found so suggestively perplexing, it has dispelled problems that have seemed insoluble mysteries to many generations of men. I do not say it has solved them, but it has dispelled them and made them irrelevant and uninteresting. So long as one believed that life span unprogressively from generation to generation, that generation followed generation unchangingly for ever, the enormous preponderance of sexual needs and emotions in life was a distressing and inexplicable fact--it was a mystery, it was sin, it was the work of the devil. One asked, why does man build houses that others may live therein; plant trees whose fruit he will never see? And all the toil and ambition, the stress and hope of existence, seemed, so far as this life went, and before these new lights came, a mere sacrifice to this pointless reiteration of lives, this cosmic _crambe repetita_. To perceive this aspect, and to profess an entire detachment from the whole vacuous business was considered by a large proportion of the more thoughtful people of the world the supreme achievement of philosophy. The acme of old-world wisdom, the ultimate mystery of Oriental philosophy is to contemn women and offspring, to abandon costume, cleanliness, and all the decencies and dignities of life, and to crawl, as scornfully as possible, but at any rate to crawl out of all these earthly shows and snares (which so obviously lead to nothing), into the nearest tub.
