What we see depends mainly on what we look for.
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.
Our duty is to believe that for which we have sufficient evidence, and to suspend our judgement when we have not.
A day of worry is more exhausting than a week of work.
When we have done our best, we should wait the result in peace.
A wise system of education will at last teach us how little man yet knows, how much he has still to learn.
We may sit in our library and yet be in all quarters of the earth.
If we are ever in doubt about what to do, it is a good rule to ask ourselves what we shall wish on the morrow that we had done.
