I want to prove to you if I can that this is all a question of intellectual development, a question of sense, and the more a man knows the more liberal he is; the less a man knows the more bigoted he is. The less a man knows the more certain he is that he knows it, and the more a man knows the better satisfied he is that he is entirely ignorant. Great knowledge is philosophic, and little, narrow, contemptible knowledge is bigoted and hateful. I want to prove it to you. I saw a little while ago models of nearly everything man has made for his use--nearly everything. I saw models of all the watercraft; from the rude dug-out, in which paddled the naked savage, with his forehead about half as high as his teeth were long--all the water craft from that dug-out up to a man of war that carries a hundred guns and miles of canvas; from that rude dug-out to a steamship that turns its brave prow from the port of New York, with three thousand miles of foaming billows before it, not missing a throb or beat of its mighty iron heart from one shore to the other. I saw their ideas of weapons, from the rude club, such as was seized by that same barbarian as he emerged from his den in the morning, hunting a snake for his dinner; from that club to the boomerang, to the dagger, to the sword, to the blunderbuss, to the old flintlock, to the cap-lock, to the needle-gun, to the cannon invented by Krupp, capable of hurling a ball weighing two thousand pounds through eighteen inches of solid steel. I saw their ideas of defensive armor, from the turtle shell which one of these gentlemen lashed upon his breast preparatory to going to war, or the skin of a porcupine, dried with the quills on, that he pulled on his orthodox head before he sallied forth. By "orthodox" I mean man who has quit growing; not simply in religion, but it everything; whenever a man is done, he is orthodox whenever he thinks he has found out all, he is orthodox whenever he becomes a drag on the swift car of progress, he is orthodox. I saw their defensive armor, from the turtle-shell and the porcupine skin to the shirts of mail of the middle ages, that defied the edge of the sword and the point of the spear. I saw their ideas of agricultural implements, from the crooked stick that was attached to the horn of an ox by some twisted straw, to the agricultural implements of today, that make it possible for a man to cultivate the soil without being an ignoramus. When they had none of these agricultural implements--when they depended upon one crop--they were superstitious, for if the frosts struck one crop they thought the gods were angry with them.
