“First, guilt-tripping doesn’t work as a campaigning strategy. If you make people feel bad about what they do, you must give them a realistic and feasible alternative. Second, pragmatism beats purism. Every time.”

“I particularly dislike the high-profile switch-off campaigns where whole cities are plunged into darkness for an hour as a supposedly symbolic gesture about energy use. So is the implication that we all need to live in constant gloom to reduce CO2 emissions?”

“At 1.24 am on 26 April 1986 Chernobyl’s Unit 4 reactor exploded after staff disabled safety systems and performed an ill-advised experiment to check – ironically enough – the reactor’s safety.”

“It would be easy to laugh this off were it not so obviously counterproductive. The idea that tackling climate change means accepting profound levels of intrusion into our everyday lives – and the economic disaster of dramatic drops in consumption and living standards – is an illusion that is actually shared by the Green left and the libertarian right.”

“I might be the only person on the face of the earth that knows you're the greatest woman on earth. I might be the only one who appreciates how amazing you are in every single thing that you do, and how you are with Spencer, "Spence," and in every single thought that you have, and how you say what you mean, and how you almost always mean something that's all about being straight and good. I think most people miss that about you, and I watch them, wondering how they can watch you bring their food, and clear their tables and never get that they just met the greatest woman alive. And the fact that I get it makes me feel good, about me.”

“Education is about finding out what form of work for you is close to being play—work you do so easily that it restores you as you go.”

“Imagine that you are stuck on a long train ride and must choose one of two books to read in order to pass the time: the first is a novel whose main character is an office worker who is essentially working to pay his monthly cable bill; the second is about someone who decides to travel in South America (and of course encounters various setbacks in the process), but who pushes beyond the boundaries of conventional American life. Which... book would you pick up to read? Indeed, which of the two characters would you rather be?”
