Excerpt from Hygiene: For Teachers
For scores and probably hundreds of thousands of years man has lived uncivilized as a wild animal, exposed to all the rigours of climate, and slowly evolved, structurally and functionally, to win as an individual in the struggle for existence and perpetuate his stock. In later times there has come about a vast revolution in his condition, brought about, first, by the acquirement of a dominion over fire and fashioning of implements; then by perfection of speech, writing, the printing-press, and the accumulation, sifting, and handing down of knowledge; and, finally, with enormously increased velocity by scientific invention of our age.
Geological evidence shows us that man, who lived twenty or thirty thousand years ago, had no less well-proportioned a body and no smaller a brain than ours. His cave drawings of animals in motion, his carvings and his stone implements, show that he was as cunning of hand as the best artist or artificer of modem days. If we could re-instil the spirit of life into some child of his, found, as the mammoth has been, perfectly preserved in ice, this child clothed and educated as one of us, would take an ordinary part in our world. But what a different world to his!
