The Picture of Dorian Gray - Oscar Wilde
""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 fool. They are all men of some intellectual power, and consequently they all appreciated me. Is that very vain of me? I think is rather vain."
Lord Henry "
