“It's better to copulate than not.”

“Anybody can look at a pretty girl and see a pretty girl. An artist can look at a pretty girl and see the old woman she will become. A better artist can look at an old woman and see the pretty girl that she used to be. But a great artist-a master-and that is what Auguste Rodin was-can look at an old woman, protray her exactly as she is...and force the viewer to see the pretty girl she used to be...and more than that, he can make anyone with the sensitivity of an armadillo, or even you, see that this lovely young girl is still alive, not old and ugly at all, but simply prisoned inside her ruined body. He can make you feel the quiet, endless tragedy that there was never a girl born who ever grew older than eighteen in her heart...no matter what the merciless hours have done to her. Look at her, Ben. Growing old doesn't matter to you and me; we were never meant to be admired-but it does to them.”

This I believe with all my heart.”

“I also think there are prices too high to pay to save the United States. Conscription is one of them. Conscription is slavery, and I don't think that any people or nation has a right to save itself at the price of slavery for anyone, no matter what name it is called. We have had the draft for twenty years now; I think this is shameful. If a country can't save itself through the volunteer service of its own free people, then I say: Let the damned thing go down the drain!”
