“Just because you said dragon demons were extinct—""I said mostly extinct."Alec jabbed a finger toward him."Mostly extinct," he said, his voice trembling with rage, "is NOTEXTINCT ENOUGH.""I see," said Jace. "I'll just have them change the entry in the demonology textbook from 'almost extinct' to 'not extinct enough for Alec. He prefers his monsters really, really extinct.' Will that make you happy?”

“Cats aren't really friendly, they're just cozying up to the dominant life-form as a hedge against extinction.”

“If you do not change, you can become extinct !”

“You know, at times like this one feels, well, perhaps extinct animals should be left extinct.”

“Of the four billion life forms which have existed on this planet, three billion, nine hundred and sixty million are now extinct. We don't know why. Some by wanton extinction, some through natural catastrophe, some destroyed by meteorites and asteroids. In the light of these mass extinctions it really does seem unreasonable to suppose that Homo sapiens should be exempt. Our species will have been one of the shortest-lived of all, a mere blink, you may say, in the eye of time.”
