Lord Arthur Goring: I love you... I love you.
Mabel: Is that your reason then?
Lord Arthur Goring: Mmm. Mabel, I said.
Mabel: I know.
Lord Arthur Goring: Well? Couldn't you you love me just a little bit in return?
Mabel: Arthur, you silly! If you knew anything about anything, which you don't, you would know that I absolutely adore you.
Lord Arthur Goring: Really?
Lord Arthur Goring: Well, why didn't you say anything before?
Mabel: Because, dear boy, you never would have believed me.
Lord Arthur Goring: Fashion is what one wears oneself. What is unfashionable is what other people wear. Other people are quite dreadful. The only possible society is oneself.
Lord Caversham: Married yet?
Lord Arthur Goring: Ask me again in half an hour.
Laura: Then I take it you reject my proposal?
Lord Arthur Goring: I'm afraid I must. For you see, as tempting as it may be, in truth it's little more than blackmail.
Lord Arthur Goring: Gertrude, it is not the perfect, but rather the imperfect who have need of love.
Gertrude: You seem to know a great deal about it all of a sudden.
Lord Arthur Goring: Oh, I hope not. All I know, Gertrude, is that it takes great courage to see the world in all its tainted glory, and still to love it. And even more courage to see it in the one you love. Gertrude, you have more courage than any woman I have ever known. Do not be afraid now to use it.
