- Margaret Scully: I picked a situation as far away as possible from what I had with you. A man who wanted me so much, he physically couldn't wait to have me. Who loved women so much, he had to have two of them. Who led a life without secrets, so there were no devastating truths to discover, because I already knew the worst. A man who was ready and able to fix what was broken between us. Only, what's really broken, Barton... is me. I left Graham tonight, I... just walked out with my coat and my car keys. You'd think that'd be the beginning of a fresh start, wouldn't you? No possessions, no personal attachments, not even a wallet. And yet... I'm gonna make the same mistakes all over again. How could I not? I'm the same person I've always been. I'm looking for the same thing. I have no idea how to find it.
- Barton Scully: You don't think you've changed?
- Margaret Scully: No. No.
- Barton Scully: I do.
- Margaret Scully: Ahh, why?
- Barton Scully: Because you left him. You didn't wait for him to leave you, like you did with me. That's the difference. That's how you've changed. You know that there's something more, something better. And you know that you deserve it. Or you would've stayed.
- Margaret Scully: ...But, I'm alone... I am all alone. I don't know what to do now. I don't... Who do I have? Where is home?
- Barton Scully: I... I think maybe I can help. I think... I think maybe I can give that back to you.
- Leslie Farber: My question, Dr. Masters, is: Where is the love?
- Dr. William Masters: Uh... In 1687 Sir Isaac Newton discovered what was then known as the 'Law of Universal Gravitation'. Gravity. Take two objects, the larger object exerts an attractive force on the smaller object, pulling it towards itself, as it where. An apple falls from a tree. The earth, by far the more massive object, pulls the apple to the ground. Simple enough. Only Newton's theory left scientists a rather puzzling problem. To paraphrase you, Dr. Farber, where is the gravity? It's not something you can see or touch, it's not something you can put under microscopes or examine from a telescope. Well, 230 years after Newton, a German patent clerk in Switzerland finally realised that scientists had been asking the wrong question all along. They would never find an object in all the immensity of space called gravity because, in point of fact, gravity is nothing but the shape of space itself. That clerk, Einstein, posited that the apple does not fall to the ground because the earth exerts some mysterious kind of force upon it. The apple falls to the ground because it is following the lines and grooves that gravity has carved into space. And when we talk about sex we do not talk about love, Dr. Farber, because love cannot be rendered into columns and graphs as if it were the same as blood pressure or heart rate. Love is not a force exerted by one body onto another. It is the very fabric of those bodies. Love is that which carves the lines and grooves. The curvature of our desire.
