I saw, too, the armor from the shell of a turtle, that one of our brave ancestors lashed upon his breast when he went to fight for his country; the skin of a porcupine, dried with the quills on, which this same savage pulled over his orthodox head, up to the shirts of mail, that were worn in the Middle Ages, that laughed at the edge of the sword and defied the point of the spear; up to a monitor clad in complete steel.
I saw at the same time, their musical instruments, from the tom-tom—that is, a hoop with a couple of strings of raw hide drawn across it—from that tom-tom, up to the instruments we have to-day, that make the common air blossom with melody.
I saw, too, their paintings, from a daub of yellow mud, to the great works which now adorn the galleries of the world. I saw also their sculpture, from the rude god with four legs, a half dozen arms, several noses, and two or three rows of ears, and one little, contemptible, brainless head, up to the figures of to-day—to the marbles that genius has clad in such a personality that it seems almost impudent to touch them without an introduction.
I saw their books—books written upon skins of wild beasts—upon shoulder-blades of sheep—books written upon leaves, upon bark, up to the splendid volumes that enrich the libraries of our day. When I speak of libraries, I think of the remark of Plato: "A house that has a library in it has a soul."
I saw their implements of agriculture, from a crooked stick that was attached to the horn of an ox by some twisted straw, to the agricultural implements of this generation, that make it possible for a man to cultivate the soil without being an ignoramus.
While looking upon these things I was forced to say that man advanced only as he mingled his thought with his labor,—only as he got into partnership with the forces of nature,—only as he learned to take advantage of his surroundings—only as he freed himself from the bondage of fear,—only as he depended upon himself—only as he lost confidence in the gods.
I saw at the same time a row of human skulls, from the lowest skull that has been found, the Neanderthal skull—skulls from Central Africa, skulls from the Bushmen of Australia—skulls from the farthest isles of the Pacific sea—up to the best skulls of the last generation;—and I noticed that there was the same difference between those skulls that there was between the products of those skulls, and I said to myself, "After all, it is a simple question of intellectual development." There was the same difference between those skulls, the lowest and highest skulls, that there was between the dug-out and the man-of-war and the steamship, between the club and the Krupp gun, between the yellow daub and the landscape, between the tom-tom and an opera by Verdi.
The first and lowest skull in this row was the den in which crawled the base and meaner instincts of mankind, and the last was a temple in which dwelt joy, liberty, and love.
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.
