Every person exceeds our power of measurement.

Never be within doors when you can rightly be without.

So much for the right books; the right use of them is another matter. The children must enjoy the book. The ideas it holds must each make that sudden, delightful impact upon their minds, must cause that intellectual stir, which mark the inception of an idea.

Every common miracle which the child sees with his own eyes makes of him for the moment another Newton.

The teacher who allows his scholars the freedom of the city of books is at liberty to be their guide, philosopher and friend; and is no longer the mere instrument of forcible intellectual feeding.

Education is a matter of the spirit. No wiser word has been said on the subject, and yet we persist in applying education from without. No one knoweth the things of the man except the spirit of man which is in him; therefore, there is no education but self-education, and as soon as a young child begins his education, he does so as a student. Our business is to give him mind stuff. Both quantity and quality are essential.

Every walk should offer some knotty problem for the children to think out-"Why does that leaf float on the water, and this pebble sink?" and so on.
