tent 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."
