“When you're with a man, no one tells you he's a creep; they don't like to; they think, well, that's her choice, perhaps ours isn't up to much either; how will we ever be sure, in this polite world? In other words, as we all know, one woman's creep is another's true love, and just as well.”

“But there is no sole person for another's heart. Souls cannot be broken and then completed by another. That's not healthy, nor wise. There are infinite possibilities as there are infinite people and some matches are better than others...Just don't say that you'll die without the other one or that you'll never love again or that you're not whole--That's the stuff of Romeo and Juliet, hasty nonsense, and you know how well that turned out...Just don't be desperate about it. That's where souls go wrong, when they think they don't have choices. The heart must make choices.”

“Perhaps I love you. Perhaps I love you very much. But probably just for this reason it would be better if we remain as we are. I think a man and a woman love each other all the more when they don't live together and when they know about each other only that they exist, and when they are grateful to each other for the fact that they exist and that they know they exist. And that alone is enough for their happiness.”

“Jake: I'm not offering up excuses of any kind... I was just saying that sometimes shit happens, and I don't have a choice.Natalie: No, Jake, that's where you're wrong. Me getting cancer? True enough, I had no choice. How you treat the ones you love? Well, there, you always have a choice.”

“Just like with love. It's all or nothing. ... That's why love is dangerous. We stand up for love. We take risks. Well, you of all people know about that - your own Soviet Russia, an entire nation rearranged to discourage love for anything other than one's country.' Because love caused people to think for themselves, to look out for themselves and their loved ones.”

“But there is one more reason to protect other species. One seldom if ever mentioned. Perhaps we are the first to talk and think and build and aspire, but we may not be the last. Others may follow us in this adventure. Some day we may be judged by just how well we served, when alone we were Earth’s caretakers.”
