There is no space here for the history of the rise and development of the movement. It provoked warm adhesion and fierce opposition from the start. Professor Hare and Horace Greeley were among the educated minority who tested and endorsed its truth. It was disfigured by many grievous incidents, which may explain but does not excuse the perverse opposition which it encountered in so many quarters. This opposition was really largely based upon the absolute materialism of the age, which would not admit that there could exist at the present moment such conditions as might be accepted in the far past. When actually brought in contact with that life beyond the grave which they professed to believe in, these people winced, recoiled, and declared it impossible. The science of the day was also rooted in materialism, and discarded all its own very excellent axioms when it was faced by an entirely new and unexpected proposition. Faraday declared that in approaching a new subject one should make up one's mind a priori as to what is possible and what is not! Huxley said that the messages, EVEN IF TRUE, "interested him no more than the gossip of curates in a cathedral city." Darwin said: "God help us if we are to believe such things." Herbert Spencer declared against it, but had no time to go into it. At the same time all science did not come so badly out of the ordeal. As already mentioned, Professor Hare, of Philadelphia, inventor, among other things, of the oxy-hydrogen blow-pipe, was the first man of note who had the moral courage, after considerable personal investigation, to declare that these new and strange developments were true. He was followed by many medical men, both in America and in Britain, including Dr. Elliotson, one of the leaders of free thought in this country. Professor Crookes, the most rising chemist in Europe, Dr. Russel Wallace the great naturalist, Varley the electrician, Flammarion the French astronomer, and many others, risked their scientific reputations in their brave assertions of the truth. These men were not credulous fools. They saw and deplored the existence of frauds. Crookes' letters upon the subject are still extant. In very many cases it was the Spiritualists themselves who exposed the frauds. They laughed, as the public laughed, at the sham Shakespeares and vulgar Caesars who figured in certain seance rooms. They deprecated also the low moral tone which would turn such powers to prophecies about the issue of a race or the success of a speculation. But they had that broader vision and sense of proportion which assured them that behind all these follies and frauds there lay a mass of solid evidence which could not be shaken, though like all evidence, it had to be examined before it could be appreciated. They were not such simpletons as to be driven away from a great truth because there are some dishonest camp followers who hang upon its skirts.
