“When I learned about this, I was told that it was “instinct.” (“Instinct” continues to be the explanation of choice whenever animal behavior implies too much intelligence.) Instinct, though, wouldn’t go very far in explaining how pigeons use human transportation routes to navigate. Pigeons follow highways and take particular exits, likely following many of the same landmarks as the humans driving below.”

“Almost always when I told someone I was writing a book about "eating animals", they assumed, even without knowing anything about my views, that it was a case for vegetarianism. It's a telling assumption, one that implies not only that a thorough inquiry into animal agriculture would lead one away from eating meat, but that most people already know that to be the case.”

“The next morning I told Mom I couldn't go to school again. She asked what was wrong. I told her, “The same thing that’s always wrong.” “You’re sick?” “I'm sad.” “About Dad?” “About everything.” She sat down on the bed next to me, even though I knew she was in a hurry. “What's everything?” I started counting on my fingers: “The meat and dairy products in our refrigerator, fistfights, car accidents, Larry–” “Who's Larry?” “The homeless guy in front of the Museum of Natural History who always says ‘I promise it’s for food’ after he asks for money.” She turned around and I zipped her dress while I kept counting. “How you don’t know who Larry is, even though you probably see him all the time, how Buckminster just sleeps and eats and goes to the bathroom and has no ‘raison d’etre’, the short ugly guy with no neck who takes tickets at the IMAX theater, how the sun is going to explode one day, how every birthday I always get at least one thing I already have, poor people who get fat because they eat junk food because it’s cheaper…” That was when I ran out of fingers, but my list was just getting started, and I wanted it to be long, because I knew she wouldn't leave while I was still going. “…domesticated animals, how I have a domesticated animal, nightmares, Microsoft Windows, old people who sit around all day because no one remembers to spend time with them and they’re embarrassed to ask people to spend time with them, secrets, dial phones, how Chinese waitresses smile even when there’s nothing funny or happy, and also how Chinese people own Mexican restaurants but Mexican people never own Chinese restaurants, mirrors, tape decks, my unpopularity in school, Grandma’s coupons, storage facilities, people who don’t know what the Internet is, bad handwriting, beautiful songs, how there won’t be humans in fifty years–” “Who said there won't be humans in fifty years?” I asked her, “Are you an optimist or a pessimist?” She looked at her watch and said, “I'm optimistic.” “Then I have some bed news for you, because humans are going to destroy each other as soon as it becomes easy enough to, which will be very soon.” “Why do beautiful songs make you sad?” “Because they aren't true.” “Never?” “Nothing is beautiful and true.”

“I watched the sheets breathe when she breathed, like how Dad used to say that trees inhale when people exhale, because I was too young to understand the truth about biological processes.”

“I decided then and there never to become someone who told jokes when explanations were impossible.”

“Cher Marcel,Allô. I am Oskar's mom. I have thought about it a ton, and I have decided that it isn't obvious why Oskar should go to French lessons, so he will no longer be going to go see you on Sundays like he used to. I want to thank you very much for everything you have taught Oskar, particularly the conditional tense, which is weird. Obviously, there's no need to call me when Oskar doesn't come to his lessons, because I already know, because this was my decision. Also, I will keep sending you checks, because you are a nice guy.Votre ami dévouée,Mademoiselle Schell.”

“The UN special envoy on food called it a 'crime against humanity' to funnel 100 million tons of grain and corn to ethanol when almost a billion people are starving. So what kind of crime is animal agriculture, which uses 756 million tons of grain and corn per year, much more than enough to adequately feed the 1.4 billion human who are living in dire poverty?”
