“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.”

“On the whole I’m glad; you can’t mourn for unborn grandchildren when there never was a hope of them. This planet is doomed anyway. Eventually the sun will explode or cool and one small insignificant particle of the universe will disappear with only a tremble. If man is doomed to perish, then universal infertility is as painless a way as any. And there are, after all, personal compensations. For the last sixty years we have sycophantically pandered to the most ignorant, the most criminal and the most selfish section of society. Now, for the rest of our lives, we’re going to be spared the intrusive barbarism of the young, their noise, their pounding, repetitive, computer-produced so-called music, their violence, their egotism disguised as idealism. My God, we might even succeed in getting rid of Christmas, that annual celebration of parental guilt and juvenile greed. I intend that my life shall be comfortable, and, when it no longer is, then I shall wash down my final pill with a bottle of claret.”

“Life has had to deal with environmental change, especially climate change, since the beginning of its existence on Earth. Species adjust or go extinct, and both have happened. For life-forms with our kinds of cells—eukaryotic, the kind with distinct organelles—the average existence of a species is about 1 million years, and, on average, one species goes extinct a year, at least of the species we have named and know, including those we know only from fossil records."-Dan Botkin, excerpt from THE MOON IN THE NAUTILUS SHELL.”

“We have all sinned, Mr. Darcy, and we cannot look for mercy without showing it in our lives.”

“We are the intelligent elite among animal life on earth and whatever our mistakes, [Earth] needs us. This may seem an odd statement after all that I have said about the way 20th century humans became almost a planetary disease organism. But it has taken [Earth] 2.5 billion years to evolve an animal that can think and communicate its thoughts. If we become extinct she has little chance of evolving another.”

“It is surely unreasonable to credit that only one small star in the immensity of the universe is capable of developing and supporting intelligent life. But we shall not get to them and they will not come to us.”

“Daniel supposed he had a secret life. Most people did; it was hardly possible to live without one.”
