"With this viewpoint in mind, he was continually trying to find connecting links by considering likenesses between man, for instance, and the various stocks inferior to him (1); and it must be admitted that in his attempt a great many unlikenesses and dissimilarities and fundamental differences, all of extreme importance, were either ignored entirely, or — may I say it? — willfully slurred over. It was the old, old story, both in Huxley's case and in Haeckel's: what was good for their theories was accepted and pressed home to the limit; and what was contrary to their theories was either ignored or suppressed. We submit that, great as these men were each in his own field, such a procedure is not a truly scientific one. We can excuse their enthusiasm; but an excuse is not by any means an extension of sympathy to the mistake."
