It is characteristic of Mr. Wells’s work that now, in 1926, he still gives in all simplicity that exploded answer, which was so fashionable in the nineties. Mr. Bernard Shaw said the other day, with native charity, that no one under seventy still believed in Natural Selection. Page 16 of this new Part I of Mr. Wells’s book shows that Mr. Shaw estimated too highly the intelligence and culture of his contemporaries. To trot out Natural Selection at this time of day as the chief agent in Evolution is almost like trotting out the old dead theory of immutable and simple elements in a popular chemistry. That is what was taught as chemistry when Mr. Wells was young, and Natural Selection was what was taught as the cause of differentiation between living beings when Mr. Wells was young. The one error is to-day nearly as obsolete as the other. There is still continuing the remains of an obstinate defence, urged by the strongest of human motives, religion: for there are still those who agree with Weissmann that Natural Selection must be maintained at all costs, and with no matter what fantastic affirmations, because “It is the only alternative to Design” in the Universe—that is, to God. But there can be no doubt which way the battle has turned. When Driesch said, twenty long years ago, “Darwinism is dead,” he was hardly premature. To quote him now is to repeat a commonplace. Let me not be misunderstood. I should not criticize Mr. Wells for ignorance if he had written thus: “Many explanations have been given of how Evolution has worked. The Ancients ascribed it to some inherent power in living things which they called ‘entelechy,’ i.e. the power to realize an end. The eighteenth century, led by Lamarck, tended at its close as did the earlier nineteenth to something similar, but emphasized the will and effort of the organism. In the mid-nineteenth century there was proposed by Darwin and Wallace a new mechanical explanation which got rid of design and of ‘an end’ to which organisms worked. Its authors called it ‘Natural Selection.’ For a short time it was so completely the fashion that it seemed impregnable. But Criticism soon began, and grew menacing by the end of the century. With the opening of the twentieth this Criticism had grown greater by far in volume and force, especially in America and on the Continent. To-day it seems overwhelming. None the less, I hold to those who with many modifications still maintain the old theory.” But Mr. Wells did not write thus, with an appreciation of the position as it stands to-day. He set down Natural Selection in all its crudity as an admitted final truth, a piece of unquestioned modern science, and left his unfortunate readers under that impression.
