This is an old-time topic of disputation. Before Mother Eddy there was Bishop Berkeley, and before Berkeley, there was Plato, and they and the materialists disputed until their hearers cried in despair, "What is Mind? No matter! What is Matter? Never mind!" But a century or two ago in a town of Prussia there lived a little, dried-up professor of philosophy, who sat himself down in his room and fixed his eyes on a church steeple outside the window, and for years on end devoted himself to examining the tools of thought with which the human mind is provided, and deciding just what work and how much of it they are fitted to do. So came the proof that our minds are incapable of reaching to or dealing with any ultimate reality whatever, but can comprehend only phenomena--that is to say, appearances--and their relations one with another. The Koenigsberg professor proved this once for all time, setting forth four propositions about ultimate reality, and proving them by exact and irrefutable logic, and then proving by equally exact and irrefutable logic their precise opposites and contraries. Anybody who has read and comprehended the four "antinomies" of Immanuel Kant[A] knows that metaphysics is as dead a subject as astrology, and that all the complicated theories which the philosophers from Heraclitus to Arthur Balfour have spun like spiders out of their inner consciousness, have no more relation to reality than the intricacies of the game of chess. [A] See Paulsen: "Life of Kant." The writer is sorry to make this statement, because he spent a lot of time reading these philosophers and acquainting himself with their subtle theories. He learned a whole language of long words, and even the special meanings which each philosopher or school of philosophers give to them. When he had got through, he had learned, so far as metaphysics is concerned, absolutely nothing, and had merely the job of clearing out of his mind great masses of verbal cobwebs. It was not even good intellectual training; the metaphysical method of thought is a _trap_. The person who thinks in absolutes and ultimates is led to believe that he has come to conclusions about reality, when as a matter of fact he has merely proved what he wants to believe; if he had wanted to believe the opposite, he could have proven that exactly as well--as his opponents will at once demonstrate.
