“I find no flaw in your reasoning about the Analytical Engine; I admire it; but you are aware that it rests entirely on the hypothesis that I care for the 'whole human race.”

“I watched as that kid died. In his last few seconds there was pure terror in his eyes. You can't do that. You can't do that to a person. I don't care what anybody tells me, I don't care how many people go crazy and die, I don't care if the whole shuck human race ends. Even if that was the only thing that had to happen to find the cure, I'd still be against it.”

“On the whole, I think you should write biographies of those you admire and respect, and novels about human beings who you think are sadly mistaken.”

“I am madly, ridiculously, passionately in love with you. I don’t care about your past. Your race does nothing to change my feelings. I love you, you stubborn little fool. Is that clear enough for you?”

“There are times when I would like to hang the whole human race, and finish the farce.”

“What I mean is, I didn't fall in love with you all as a whole. I fell in love with each of you because of who you are. I don't care about you because you come with Mara. I care about you because you're a good kid. You're smart. You're loyal. And you love and look out for your sister and Mara. I know grown men who do not have a character as fine as yours. Those are the reasons I love you. There are different reasons I love Billie. And there are different reasons I love Mara. Today, what we had together was good. But the feelings I feel for you aren't feelings I have to have in order to have Mara. They're feelings you earned. Now, you with me?”
