Art is unquestionably one of the purest and highest elements in human happiness. It trains the mind through the eye, and the eye through the mind. As the sun colors flowers, so does art color life.

A wise system of education will at least teach us how little man yet knows, how much he has still to learn.

Earth and sky, woods and fields, lakes and rivers, the mountain and the sea, are excellent schoolmasters, and teach some of us more than we can ever learn from books.

The important thing is not so much that every child should be taught, as that every child should be given the wish to learn.

Those who have not distinguished themselves at school need not on that account be discouraged. the greatest minds do not necessarily ripen the quickest.
