the same field, it followed that the economic self-interest of the learned classes would instinctively and almost invariably be opposed to reform or advance of thought in their fields. "Being human, they were scarcely more to be blamed for involuntarily regarding new ideas in their specialties with aversion than the weaver or the brickmaker for resisting the introduction of inventions calculated to take the bread out of his mouth. And yet consider what a tremendous, almost insurmountable, obstacle to human progress was presented by the fact that the intellectual leaders of the nations and the molders of the people's thoughts, by their economic dependence upon vested interests in established ideas, were biased against progress by the strongest motives of self-interest. When we give due thought to the significance of this fact, we shall find ourselves wondering no longer at the slow rate of human advance in the past, but rather that there should have been any advance at all." CHAPTER XXVIII. HOW THE PROFIT SYSTEM NULLIFIED THE BENEFIT OF INVENTIONS. "The general subject of the hostility of private capitalism to progress," pursued the teacher, "divides itself, as I said, into two branches. First, the constitutional antagonism between a system of distinct and separate vested interests and all unsettling changes which, whatever their ultimate effect, must be directly damaging to those interests. We will now ask you, Harold, to take up the second branch of the subject--namely, the effect of the profit principle to minimize, if not wholly to nullify, the benefit to the community of such inventions and improvements as were able to overcome the antagonism of vested interests so far as to get themselves introduced. The nineteenth century, including the last quarter of the eighteenth, was marked by an astonishing and absolutely unprecedented number of great inventions in economic processes. To what was this outburst of inventive genius due?" "To the same cause," replied the boy, "which accounts for the rise of the democratic movement and the idea of human equality during the same period--that is to say, the diffusion of intelligence among the masses, which, for the first time becoming somewhat general, multiplied ten-thousandfold the thinking force of mankind, and, in the political aspect of the matter, changed the purpose of that thinking from the interest of the few to that of the many." "Our ancestors," said the teacher, "seeing that this outburst of invention took place under private capitalism, assumed that there must be something in that system peculiarly favorable to the genius of invention. Have you anything to say on that point beyond what has been said?" "Nothing," replied the boy, "except that by the same rule we ought to give credit to the institutions of royalty, nobility, and plutocracy for the democratic idea which under their fostering influence during the same period grew to flowering in the great Revolution."
