In short, the metaphysicians have done nothing, absolutely nothing, for mankind. Step by step, before the advance of science, they have been driven back. As fast as the ascertained facts of science have overthrown their subjective explanations of things, they have made new subjective explanations of things, including explanations of the latest ascertained facts. And this, I doubt not, they will go on doing to the end of time. Gentlemen, a metaphysician is a medicine man. The difference between you and the Eskimo who makes a fur-clad blubber-eating god is merely a difference of several thousand years of ascertained facts. That is all."

"Yet the thought of Aristotle ruled Europe for twelve centuries," Dr. Ballingford announced pompously. "And Aristotle was a metaphysician."

Dr. Ballingford glanced around the table and was rewarded by nods and smiles of approval.

"Your illustration is most unfortunate," Ernest replied. "You refer to a very dark period in human history. In fact, we call that period the Dark Ages. A period wherein science was raped by the metaphysicians, wherein physics became a search for the Philosopher's Stone, wherein chemistry became alchemy, and astronomy became astrology. Sorry the domination of Aristotle's thought!"

Dr. Ballingford looked pained, then he brightened up and said:

"Granted this horrible picture you have drawn, yet you must confess that metaphysics was inherently potent in so far as it drew humanity out of this dark period and on into the illumination of the succeeding centuries."

"Metaphysics had nothing to do with it," Ernest retorted.

"What?" Dr. Hammerfield cried. "It was not the thinking and the speculation that led to the voyages of discovery?"

"Ah, my dear sir," Ernest smiled, "I thought you were disqualified.
