There are two freedoms - the false, where a man is free to do what he likes; the true, where he is free to do what he ought.

There's no use doing a kindness if you do it a day too late.

Study nature as the countenance of God.

Have charity; have patience; have mercy. Never bring a human being, however silly, ignorant, or weak--above all, any little child--to shame and confusion of face. Never by petulance, by suspicion, by ridicule, even by selfish and silly haste--never, above all, by indulging in the devilish pleasure of a sneer--crush what is finest and rouse up what is coarsest in the heart of any fellow-creature.

Do noble things, not dream them all day long: And so make Life, Death, and the vast Forever one grand, sweet song.

I go at what I have to do as if there were nothing else in the world for me to do.
