Context

“"Don't talk like that about any one you love, Dorian. Love is a more wonderful thing than art." "They are both simply forms of imitation," remarked Lord Henry. "But do let us go. Dorian, you must not stay here any longer. It is not good for one's morals to see bad acting. Besides, I don't suppose you will want your wife to act, so what does it matter if she plays Juliet like a wooden doll? She is very lovely, and if she knows as little about life as she does about acting, she will be a delightful experience.” source
