Cecil Graham: What is a cynic?
Lord Darlington: A man who knows the price of everything, and the value of nothing.
Cecil Graham: And a sentimentalist, my dear Darlington, is a man who sees an absurd value in everything and doesn’t know the market price of any single thing.

I am but too conscious of the fact that we are born in an age when only the dull are treated seriously, and I live in terror of not being misunderstood. Don't degrade me into the position of giving you useful information. Education is an admirable thing, but it is well to remember from time to time that nothing that is worth knowing can be taught.

It is a curious fact that people are never so trivial as when they take themselves seriously.

The world is a stage and the play is badly cast.

No good deed goes unpunished.

You silly Arthur! If you knew anything about...anything, which you don't, you would know that I adore you. Everyone in London knows it except you. It is a public scandal the way I adore you. I have been going about for the last six months telling the whole of society that I adore you. I wonder you consent to have anything to say to me. I have no character left at all. At least, I feel so happy that I am quite sure I have no character left at all.
