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.

I cannot, however, but think that the world would be better and brighter if our teachers would dwell on the Duty of Happiness as well as the Happiness of Duty; for we ought to be as cheerful as we can, if only because to be happy ourselves is a most effectual contribution to the happiness of others.

The whole value of solitude depends upon oneself; it may be a sanctuary or a prison, a haven of repose or a place of punishment, a heaven or a hell, as we ourselves make it.

Rest is not idleness, and to lie sometimes on the grass under trees on a summer's day, listening to the murmur of the water, or watching the clouds float across the sky, is by no means a waste of time.

Our duty is to believe that for which we have sufficient evidence, and to suspend our judgment when we have not.

If we are ever in doubt what to do, it is a good rule to ask ourselves what we shall wish on the morrow that we had done.

If we succeed in giving the love of learning, the learning itself is sure to follow.

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