It was a workmanlike effort illustrated with facts, dates and figures. Though it rose to no height of eloquence it contained much which needed an answer. And the sad fact emerged that Challenger was not in a position to answer. He had read up his own case but had neglected that of his adversary, accepting too easily the facile and specious presumptions of incompetent writers who handled a matter which they had not themselves investigated. Instead of answering, Challenger lost his temper. The lion began to roar. He tossed his dark mane and his eyes glowed, while his deep voice reverberated through the hall. Who were these people who took refuge behind a few honoured but misguided names? What right had they to expect serious men of science to suspend their labours in order to waste time in examining their wild surmises? Some things were self-evident and did not require proof. The onus of proof lay with those who made the assertions. If this gentleman, whose name is unfamiliar, claims that he can raise spirits, let him call one up now before a sane and unprejudiced audience. If he says that he receives messages, let him give us the news in advance of the general agencies. («It has often been done!» from the Spiritualists.) So you say, but I deny it. I am too accustomed to your wild assertions to take them seriously. (Uproar, and Judge Gaverson upon his feet.) If he claims that he has higher inspiration, let him solve the Peckham Rye murder. If he is in touch with angelic beings, let him give us a philosophy which is higher than mortal mind can evolve. This false show of science, this camouflage of ignorance, this babble about ectoplasm and other mythical products of the psychic imagination was mere obscurantism, the bastard offspring of superstition and darkness. Wherever the matter was probed one came upon corruption and mental putrescence. Every medium was a deliberate impostor. («You are a liar!» in a woman's voice from the neighbourhood of the Lindens.) The voices of the dead had uttered nothing but childish twaddle. The asylums were full of the supporters of the cult and would be fuller still if everyone had his due.
It was a violent but not an effective speech. Evidently the great man was rattled. He realized that there was a case to be met and that he had not provided himself with the material wherewith to meet it. Therefore he had taken refuge in angry words and sweeping assertions which can only be safely made when there is no antagonist present to take advantage of them. The Spiritualists seemed more amused than angry. The materialists fidgeted uneasily in their seats. Then James Smith rose for his last innings. He wore a mischievous smile. There was quiet menace in his whole bearing.
He must ask, he said, for a more scientific attitude from his illustrious opponent. It was an extraordinary fact that many scientific men, when their passions and prejudices were excited, showed a ludicrous disregard for all their own tenets. Of these tenets there was none more rigid than that a subject should be examined before it was condemned. We have seen of late years, in such matters as wireless or heavier-than-air machines, that the most unlikely things may come to pass. It is most dangerous to say a priori that a thing is impossible. Yet this was the error into which Professor Challenger had fallen. He had used the fame which he had rightly won in subjects which he had mastered in order to cast discredit upon a subject which he had not mastered. The fact that a man was a great physiologist and physicist did not in itself make him an authority upon psychic science.
