If youth, throughout all history, had had a champion to stand up for it; to show a doubting world that a child can think; and, possibly, do it practically; you wouldnt constantly run across folks today who claim that a child dont know anything.A childs brain starts functioning at birth; and has, amongst its many infant convolutions, thousands of dormant atoms, into which God has put a mystic possibility for noticing an adults act, and figuring out its purport.
Up to about its primary school days a child thinks, naturally, only of play. But many a form of play contains disciplinary factors. You cant do this, or that puts you out, shows a child that it must think, practically or fail. Now, if, throughout childhood, a brain has no opposition, it is plain that it will attain a position of status quo, as with our ordinary animals. Man knows not why a cow, dog or lion was not born with a brain on a par with ours; why such animals cannot add, subtract, or obtain from books and schooling, that paramount position which Man holds today.
But a human brain is not in that class. Constantly throbbing and pulsating, it rapidly forms opinions; attaining an ability of its own; a fact which is startlingly shown by an occasional child prodigy in music or school work. And as, with our dumb animals, a childs inability convincingly to impart its thoughts to us, should not class it as ignorant
