“Nature uses as little as possible of anything.”

“Anything's possible with an angel and a little ingenuity.”

“Young people seldom turn out as one predicts, so it is of little use to expect anything,' said Mrs. Meg with a sigh. 'If our children are good and useful men and women, we should be satisfied; yet it's very natural to wish them to be brilliant and successful.”

“...much theological discussion is wasted, not because the words used have no possible meaning, but because the people who use them don't mean anything by them.”
