“Why are you so interested in amoebas?""Oh, they're immortal," he said, "and sort of shapeless and flexible. Being aperson is getting too complicated.”

“Immortality,' said Crake, ' is a concept. If you take 'mortality' as being, not death, but the foreknowledge of it and the fear of it, then 'immortality' is the absence of such fear. Babies are immortal. Edit out the fear, and you'll be...”

“Glenn used to say the reason you can't really imagine yourself being dead was that as soon as you say, 'I'll be dead,' you've said the word I, and so you're still alive inside the sentence. And that's how people got the idea of the immortality of the soul - it was a consequence of grammar.”

“Toast is when you take a piece of bread—What is bread? Bread is when you take some flour—What is flour? We’ll skip that part, it’s too complicated. Bread is something you can eat, made from a ground-up plant and shaped like a stone. You cook it... Please, why do you cook it? Why don’t you just eat the plant? Never mind that part—Pay attention. You cook it, and then you cut it into slices, and you put a slice into a toaster, which is a metal box that heats up with electricity—What is electricity? Don’t worry about that. While the slice is in the toaster, you get out the...”

“The male frog, in mating season," said Crake, "makes as much noise as it can. The females are attracted to the male frog with the biggest, deepest voice because it suggests a more powerful frog, one with superior genes. Small male frogs - it's been documented - discover that if they position themselves in empty drainpipes, the pipe acts as a voice amplifier, and the small frog appears much larger than it really is.""So?""So that's what art is, for the artist," said Crake. "An empty drainpipe. An amplifier. A stab at getting laid.""Your analogy falls down when it comes to female artists," said Jimmy. "They're not in it to get laid. They'd gain no biological advantage from amplifying themselves, since potential mates would be deterred rather than attracted by this sort of amplification. Men aren't frogs, they don't want women who are ten times bigger than them.""Female artists are biologically confused," said Crake.”

“I've learned to do without a lot of things. If you have a lot of things, said Aunt Lydia, you get too attached to this material world and you forget about spiritual values.”
