“But that can't work, can it?" Said Richard. "If we do that, then this won't have happened. Don't we generate all sorts of paradoxes?"Reg stirred himself from thought. "No worse than many that exist already," he said. "If the universe came to an end every time there was some uncertainty about what had happened in it, it would never have got beyond the first picosecond. And many of course don't. It's like a human body, you see. A few cuts and bruises here and there don't hurt it. Not even major surgery if its done properly. Paradoxes are just the scar tissue. Time and space heal themselves up around them and people simply remember a version of events which makes as much sense as they require it to make. That isn't to say if you get involved in a paradox a few things won't strike you as being very odd, but if you've got through life without that already happening to you, then I don't know which universe you've been living in, but it isn't this one”

“A sad fact, of course, about adult life is that you see the very things you'll never adapt to coming toward you on the horizon. You see them as the problems they are, you worry like hell about them, you make provisions, take precautions, fashion adjustments; you tell yourself you'll have to change your way of doing things. Only you don't. You can't. Somehow it's already too late. And maybe it's even worse than that: maybe the thing you see coming from far away is not the real thing, the thing that scares you, but its aftermath. And what you've feared will happen has already taken place. This is similar in spirit to the realization that all the great new advances of medical science will have no benefit for us at all, thought we cheer them on, hope a vaccine might be ready in time, think things could still get better. Only it's too late there too. And in that very way our life gets over before we know it. We miss it. And like the poet said: The ways we miss our lives are life.”

“No, you don't understand because it isn't happening to you, and no one can understand but me. I don't blame you. You've got your job to do, and your Ph.D. to get, and-oh, yes don't tell me, I know you're in this largely out of love of humanity, but you've got your life to live and we don't happen to belong on the same level. I passed your floor on the way up, nad now I'm passing it on the way down, and I don't think I'll be taking this elevator again. So let's just say good-bye here and now.”

“You get through bad things - I know, enough bad things have happened to me already. But I don't think getting through one bad time makes it any easier to deal with the next one. If anything, it's worse, because there is happiness to remember.”

“We face up to awful things because we can't go around them, or forget them. The sooner you say 'Yes, it happened, and there's nothing I can do about it,' the sooner you can get on with your own life. You've got children to bring up. So you've got to get over it. What we have to get over, somehow we do. Even the worst things.”
