Attempts at religious reform aroused popular anger because the inborn conservativeness of man is nowhere stronger than in the field of religion. The religion of his fathers must not be criticized, even if his own profession of it is but an outward show. The most malicious kind of hatred is that which is built upon a theological foundation. On the other hand, the resistance to scientific novelties was due to an intuitive, if unconscious, appreciation of their revolutionary nature. The slightest and the most innocent scientific innovation is but a wedge which is bound to penetrate deeper and deeper, and the advance of which will soon be impossible to resist. Conservative people are undoubtedly right in their distrust and hatred of science, for the scientific spirit is the very spirit of innovation and adventure—the most reckless kind of adventure into the unknown. And such is its aggressive strength that its revolutionary activity can neither be restrained nor restricted within its own field. Sooner or later it will go out to conquer other fields and to throw floods of light into all the dark places where superstition and injustice are still rampant. The scientific spirit is the greatest force for construction but also for destruction.
