Thomas Paine, The Age of Reason:
“The apology that is sometimes made for continuing to teach the dead languages is, that they are taught at a time when a child is not capable of exerting any other mental faculty than that of memory. But this is altogether erroneous. The human mind has a natural disposition to scientific knowledge, and to the things connected with it. The first and favourite amusement of a child, even before it begins to play, is that of imitating the works of man. It builds houses with cards or sticks; it navigates the little ocean of a bowl of water with a paper boat; or dams the stream of a gutter, and contrives something which it calls a mill; and it interests itself in the fate of its works with a care that resembles affection. It afterwards goes to school, where its genius is killed by the barren study of a dead language, and the philosopher is lost in the linguist.
But the apology that is now made for continuing to teach the dead languages could not be the cause at first of cutting down learning to the narrow and humble sphere of linguistry; the cause, therefore, must be sought for elsewhere. In all researches of this kind, the best evidence that can be produced is the internal evidence the thing carries with itself, and the evidence of circumstances that unites with it, both of which, in this case, are not difficult to be discovered.”
