fuses all particular sciences into one great science. As Spencer says, the data of any particular science are partially unified knowledge. Philosophy unifies the knowledge that is contributed by all the sciences. Philosophy is the science of science, the master science, if you please. How do you like my definition?”
“Very creditable, very creditable,” Dr. Hammerfield muttered lamely.
But Ernest was merciless.
“Remember,” he warned, “my definition is fatal to metaphysics. If you do not now point out a flaw in my definition, you are disqualified later on from advancing metaphysical arguments. You must go through life seeking that flaw and remaining metaphysically silent until you have found it.”
Ernest waited. The silence was painful. Dr. Hammerfield was pained. He was also puzzled. Ernest’s sledge-hammer attack disconcerted him. He was not used to the simple and direct method of controversy. He looked appealingly around the table, but no one answered for him. I caught father grinning into his napkin.
“There is another way of disqualifying the metaphysicians,” Ernest said, when he had rendered Dr. Hammerfield’s discomfiture complete. “Judge them by their works. What have they done for mankind beyond the spinning of airy fancies and the mistaking of their own shadows for gods? They have added to the gayety of mankind, I grant; but what tangible good have they wrought for mankind? They philosophized, if you will pardon my misuse of the word, about the heart as the seat of the emotions, while the scientists were formulating the circulation of the blood. They declaimed about famine and pestilence as being scourges of God, while the scientists were building granaries and draining cities. They builded gods in their own shapes and out of their own desires, while the scientists were building roads and bridges. They were describing the earth as the centre of the universe, while the scientists were discovering America and probing space for the stars and the laws of the stars. 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. You have not yet picked out the flaw in my definition of philosophy. You are now on an unsubstantial basis. But it is the way of the metaphysicians, and I forgive you. No, I repeat, metaphysics had nothing to do with it. Bread and butter, silks and jewels, dollars and cents, and, incidentally, the closing up of the overland trade-routes to India, were the things that caused the voyages of discovery. With the fall of Constantinople, in 1453, the Turks blocked the way of the caravans to India. The traders of Europe had to find another route. Here was the original cause for the voyages of discovery. Columbus sailed to find a new route to the Indies. It is so stated in all the history books. Incidentally, new facts were learned about the nature, size, and form of the earth, and the Ptolemaic system went glimmering.”
Dr. Hammerfield snorted.
“You do not agree with me?” Ernest queried. “Then wherein am I wrong?”
“I can only reaffirm my position,” Dr. Hammerfield retorted tartly. “It is too long a story to enter into now.”
“No story is too long for the scientist,” Ernest said sweetly. “That is why the scientist gets to places. That is why he got to America.”
I shall not describe the whole evening, though it is a joy to me to recall every moment, every detail, of those first hours of my coming to know Ernest Everhard.
Battle royal raged, and the ministers grew red-faced and excited, especially at the moments when Ernest called them romantic philosophers, shadow-projectors, and similar things. And always he checked them back to facts. “The fact, man, the irrefragable fact!” he would proclaim triumphantly, when he had brought one of them a cropper. He bristled with facts. He tripped them up with facts, ambuscaded them with facts, bombarded them with broadsides of facts.
“You seem to worship at the shrine of fact,” Dr. Hammerfield taunted him.
“There is no God but Fact, and Mr. Everhard is its prophet,” Dr. Ballingford paraphrased.
Ernest smilingly acquiesced.
“I’m like the man from Texas,” he said. And, on being solicited, he explained. “You see, the man from Missouri always says, ‘You’ve got to show me.’ But the man from Texas says, ‘You’ve got to put it in my hand.’ From which it is apparent that he is no metaphysician.”
Another time, when Ernest had just said that the metaphysical philosophers could never stand the test of truth, Dr. Hammerfield suddenly demanded:
“What is the test of truth, young man? Will you kindly explain what has so long puzzled wiser heads than yours?”
“Certainly,” Ernest answered. His cocksureness irritated them. “The wise heads have puzzled so sorely over truth because they went up into the air after it. Had they remained on the solid earth, they would have found it easily enough—ay, they would have found that they themselves were precisely testing truth with every practical act and thought of their lives.”
“The test, the test,” Dr. Hammerfield repeated impatiently. “Never mind the preamble. Give us that which we have sought so long—the test of truth. Give it us, and we will be as gods.”
There was an impolite and sneering scepticism in his words and manner that secretly pleased most of them at the table, though it seemed to bother Bishop Morehouse.
“Dr. Jordan9 has stated it very clearly,” Ernest said. “His test of truth is: ‘Will it work? Will you trust your life to it?’”
“Pish!” Dr. Hammerfield sneered. “You have not taken Bishop Berkeley10 into account. He has never been answered.”
“The noblest metaphysician of them all,” Ernest laughed. “But your example is unfortunate. As Berkeley himself attested, his metaphysics didn’t work.”
Dr. Hammerfield was angry, righteously angry. It was as though he had caught Ernest in a theft or a lie.
“Young man,” he trumpeted, “that statement is on a par with all you have uttered to-night. It is a base and unwarranted assumption.”
“I am quite crushed,” Ernest murmured meekly. “Only I don’t know what hit me. You’ll have to put it in my hand, Doctor.”
“I
