“Do I fear death? No, I am not afraid of being dead because there's nothing to be afraid of, I won't know it. I fear dying, of dying I feel a sense of waste about it and I fear a sordid death, where I am incapacitated or imbecilic at the end which isn't something to be afraid of, it's something to be terrified of.”

“In a sense I want the same thing that my grandfather wanted, that people should not suffer. Yet I am not like him. He remade himself so that he could live for eternity. Yet he never defeated the eternal enemy - no, not the cyborgs or the robots. The enemy is fear, simple fear. Grandfather was always afraid of suffering.I am not afraid. I want something more for people. I want them to be happy, and I believe our suffering as a race can eventually bring us to a place of great wonder. For all I have suffered since I came back in time, I have been happy to be alive.”

“To be the father of growing daughters is to understand something of what Yeats evokes with his imperishable phrase 'terrible beauty.' Nothing can make one so happily exhilarated or so frightened: it's a solid lesson in the limitations of self to realize that your heart is running around inside someone else's body. It also makes me quite astonishingly calm at the thought of death: I know whom I would die to protect and I also understand that nobody but a lugubrious serf can possibly wish for a father who never goes away.”

“I tell people not to be afraid of their fears; because their fears are not there to scare them, they're there to let them know that something is worth it. Yet I am often afraid. I guess that means in my life, lots of things have been worth it!”

“What do you regard as the lowest depth of misery? (Just to give you an idea, Proust's reply was 'To be separated from Mama.') I think that the lowest depth of misery ought to be distinguished from the highest pitch of anguish. In the lower depths come enforced idleness, sexual boredom, and/or impotence. At the highest pitch, the death of a friend or even the fear of the death of a child.”

“If I convert it's because it's better that a believer dies than that an atheist does.”

“We juggle priceless eggs in variable gravity. I am afraid. I will taste fear until I die.”
