“I make a great difference between people. I choose my friends for their good looks, my acquaintances for their good characters, and my enemies for their good intellects. A man cannot be too careful in the choice of his enemies. I have not got one who is a fool. They are all men of some intellectual power, and consequently they all appreciate me. Is that very vain of me? I think it is rather vain.”

"He hasn't as good a one as himself anywhere."Except sometimes," replied Morris Bolter, assuming the air of a man of the world. "Some people are nobody's enemies but their own, yer know."Don't believe that!" said the Jew. "When a man's his own enemy, it's only because he's too much his own friend; not because he's careful for everybody but himself. Pooh! Pooh! There ain't such a thing in nature.”
