Hence on false premises was built up that belief in spirits or invisible beings outside ourselves, which by some curious atavism was re-emerging in modern days among the less educated strata of mankind. It was the duty of Science to resist retrogressive tendencies of the sort, and it was a sense of that duty which had reluctantly drawn him from the privacy of his study to the publicity of this platform. He rapidly sketched the movement as depicted by its maligners. It was a most unsavoury story as he told it, a story of cracking toe joints, of phosphorescent paint, of muslin ghosts, of a nauseous sordid commission trade betwixt dead men’s bones on one side, and widows’ tears upon the other. These people were the hyenas of the human race who battened upon the graves. (Cheers from the rationalists and ironical laughter from the Spiritualists.) They were not all rogues. (“Thank you, Professor!” from a stentorian opponent.) But the others were fools (laughter). Was it exaggeration to call a man a fool who believed that his grandmother could rap out absurd messages with the leg of a dining-room table? Had any savages descended to so grotesque a superstition? These people had taken dignity from death and had brought their own vulgarity into the serene oblivion of the tomb. It was a hateful business. He was sorry to have to speak so strongly, but only the knife or the cautery could deal with so cancerous a growth. Surely man need not trouble himself with grotesque speculations as to the nature of life beyond the grave. We had enough to do in this world. Life was a beautiful thing. The man who appreciated its real duties and beauties would have sufficient to employ him without dabbling in pseudo sciences which had their roots in frauds, exposed already a hundred times and yet finding fresh crowds of foolish devotees whose insane credulity and irrational prejudice made them impervious to all argument. Such is a most bald and crude summary of this powerful opening argument. The materialists roared their applause; the Spiritualists looked angry and uneasy, while their spokesman rose, pale but resolute, to answer the ponderous onslaught.
