...our enjoyment of the great works of literature depends more upon the depth of our sympathy than upon our understanding.

I seldom think about my limitations, and they never make me sad. Perhaps there is just a touch of yearning at times; but it is vague, like a breeze among flowers.

My optimism is grounded in two worlds, myself and what is about me. I demand that the world be good, and lo, it obeys. I proclaim the world good, and facts range themselves to prove my proclamation overwhelmingly true.

This world is so full of care and sorrow that it is a gracious debt we owe to one another to discover the bright crystals of delight hidden in somber circumstances and irksome tasks.
