With regard to this matter, as with regard to opposition in general to science, President Jordan has once more set forth the realities of the situation so as to make it clear that, even when it was the dogmatic spirit that was behind the refusal to accept certain scientific truths, not only was there the best of intentions in this in all cases, but in nearly all, the results were such as to benefit mankind, and even to help rather than hinder science. He says: "The desire of dogmatism to control action is in its essence the desire to save men from their own folly. The great historic churches have existed 'for the benefit of the weak and the poor.' By their observances they have stimulated the spirit of devotion. By their commands they have protected men from unwise action. By their condemnations they have saved men from the grasp of vice and crime." The ultra-conservatism which is the real factor at fault in these cases exists in all men beyond middle life. It is a wise provision of nature very probably to prevent the young and headstrong from running away with the race. We would be plunged into all sorts of curious experimental conditions only for the fact that those beyond middle life act as a brake on the initiative of their juniors. While it does some harm, there is no doubt of its supremely beneficial effects in the long run. {396} For one announced great discovery that proves its actual right to the title, there are at least a hundred that are proclaimed with loud blare of trumpet, yet prove nonentities. This sometimes becomes a very troublesome brake on progress, however. Some three hundred years ago, Harvey said with regard to his epoch-making discovery of the circulation of the blood, that he did not expect any of his contemporaries who was over forty years of age to accept it. His premonition in this matter was fully confirmed by the event. Darwin, I believe, once remarked that he did not think that men of his own age in his own generation would accept his theory, and most of them did not. The opposition which, as a consequence of this natural conservatism, is so constantly ready to manifest itself, is as human as the envy which, much as we may bewail the fact, accompanies all individual success. A history of this phase of scientific progress is of itself very interesting and of great psychological importance. A short sketch of it will serve the purpose of placing the opposition of churchmen to science in the category where it belongs, and will make this subject appear in its true light of a very natural and universal psychic manifestation, not a religious or supposed theological phenomenon.
