The deepest principle in human nature is the craving to be appreciated.

The mind, in short, works on the data it receives very much as a sculptor works on his block of stone. In a sense the statue stoodthere from eternity. But there were a thousand different ones beside it, and the sculptor alone is to thank for having extricated this one from the rest.

No reception without reaction, no impression without correlative expression, -this is the great maxim which the teacher ought never to forget.

The further limits of our being plunge, it seems to me, into an altogether other dimension of existence from the sensible and merely understandable world. Name it the mystical region, or the supernatural region, whichever you choose. So far as our ideal impulses originate in this region (and most of them do originate in it, for we find them possessing us in a way for which we cannot articulately account), we belong to it in a more intimate sense than that in which we belong to the visible world, for we belong in the most intimate sense wherever our ideals belong.

Feed the growing human being, feed him with the sort of experience for which from year to year he shows a natural craving, and he will develop in adult life a sounder sort of mental tissue, even though he may seem to be 'wasting' a great deal of his growing time, in the eyes of those for whom the only channels of learning are books and verbally communicated information.
