“To be good, and do good, is the whole duty of man comprised in a few words.”

“If we speak of direct means for the culture of the imagination, the whole is comprised in two words--food and exercise.”

“A dutiful wife enables a good man to add her hands to his own for self-applause.”

“Good works do not make a good man, but a good man does good works; evil works do not make a wicked man, but a wicked man does evil works.”

“I don't aspire to be a good man. I aspire to be a whole man.”

“The last word in ignorance is the man who says of an animal or plant, "What good is it?" If the land mechanism as a whole is good, then every part is good, whether we understand it or not. If the biota, in the course of aeons, has built something we like but do not understand, then who but a fool would discard seemingly useless parts? To keep every cog and wheel is the first precaution of intelligent tinkering.”
