It is all a question of brain, of intellectual development. If we are nearer free than were our fathers, it is because we have better heads upon the average, and more brains in them. Now, I ask you to be honest with me. It makes no difference to you what I believe, nor what I wish to prove. I simply ask you to be honest. Divest your minds, for a moment at least, of all religious prejudice. Act, for a few moments, as though you were men and women. Suppose the king, if there was one, and the priest, if there was one, at the time this gentleman floated in the dug-out, and charmed his ears with the music of the tom-tom, had said: "That dug-out is the best boat that ever can be built by man; the pattern of that came from on high, from the great god of storm and flood, and any man who says that he can improve it by putting a mast in it, with a sail upon it, is an infidel, and shall be burned at the stake;" what, in your judgment--honor bright--would have been the effect upon the circumnavigation of the globe? Suppose the king, if there was one, and the priest, if there was one--and I presume there was a priest, because it was a very ignorant age--suppose this king and priest had said: "That tom-tom is the most beautiful instrument of music of which any man can conceive; that is the kind of music they have in heaven; an angel sitting upon the edge of a fleecy cloud, golden in the setting sun, playing upon that tom-tom, became so enraptured, so entranced with her own music, that in a kind of ecstasy she dropped it--that is how we obtained it; and any man who says that it can be improved by putting a back and front to it, and four strings, and a bridge, and getting a bow of hair with rosin, is a blaspheming wretch, and shall die the death,"--I ask you, what effect would that have had upon music? If that course had been pursued, would the human ears, in your judgment, ever have been enriched with the divine symphonies of Beethoven? Suppose the king, if there was one, and the priest, had said: "That crooked stick is the best plow that can be invented: the pattern of that plow was given to a pious farmer in a holy dream, and that twisted straw is the _ne plus ultra_ of all twisted things, and any man who says he can make an improvement upon that plow, is an atheist;" what, in your judgment, would have been the effect upon the science of agriculture? But the people said, and the king and priest said: "We want better weapons with which to kill our fellow christians; we want better plows, better music, better paintings, and whoever will give us better weapons, and better music, better houses to live in, better clothes, we will robe him in wealth, and crown him with honor." Every incentive was held out to every human being to improve these things. That is the reason the club has been changed to a cannon, the dug-out to a steamship, the daub to a painting; that is the reason that the piece of rough and broken stone finally became a glorified statue.
