Be it known then that Challenger, greatly despising all opposition and with no knowledge of the real strength of the case to be answered, had, in a fatal moment, actually asserted that he would descend from Olympus and would meet in debate any representative whom the other party should select. “I am well aware,” he wrote, “that by such condescension I, like any other man of science of equal standing, run the risk of giving a dignity to these absurd and grotesque aberrations of the human brain which they could otherwise not pretend to claim, but we must do our duty to the public, and we must occasionally turn from our serious work and spare a moment in order to sweep away those ephemeral cobwebs which might collect and become offensive if they were not dispersed by the broom of Science.” Thus, in a most self-confident fashion, did Goliath go forth to meet his tiny antagonist, an ex-printer’s assistant and now the editor of what Challenger would describe as an obscure print devoted to matters of the spirit. The particulars of the debate are public property, and it is not necessary to tell in any great detail that painful event. It will be remembered that the great man of Science went down to the Queen’s Hall accompanied by many rationalist sympathisers who desired to see the final destruction of the visionaries. A large number of these poor deluded creatures also attended, hoping against hope that their champion might not be entirely immolated upon the altar of outraged Science. Between them the two factions filled the hall, and glared at each other with as much enmity as did the Blues and the Greens a thousand years before in the Hippodrome of Constantinople. There on the left of the platform were the solid ranks of those hard and unbending rationalists who look upon the Victorian agnostics as credulous, and refresh their faith by the periodical perusal of the _Literary Gazette_ and the _Freethinker_.
