“We middles see the world in shades of grey rather than in the clear blacks and whites of committed animal activists and their equally vociferous opponents”

“The inconsistencies that haunt our relationships with animals also result from the quirks of human cognition. We like to think of ourselves as the rational species. But research in cognitive psychology and behavioral economics shows that our thinking and behavior are often completely illogical. In one study, for example, groups of people were independently asked how much they would give to prevent waterfowl from being killed in polluted oil ponds. On average, the subjects said they would pay $80 to save 2,000 birds, $78 to save 20,000 birds, and $88 to save 200,000 birds. Sometimes animals act more logically than people do; a recent study found that when picking a new home, the decisions of ant colonies were more rational than those of human house-hunters. What is it about human psychology that makes it so difficult for us to think consistently about animals? The paradoxes that plague our interactions with other species are due to the fact that much of our thinking is a mire of instinct, learning, language, culture, intuition, and our reliance on mental shortcuts.”

“Psycholinguists argue about whether language reflects our perception of reality or helps create them. I am in the latter camp. Take the names we give the animals we eat. The Patagonian toothfish is a prehistoric-looking creature with teeth like needles and bulging yellowish eyes that lives in deep waters off the coast of South America. It did not catch on with sophisticated foodies until an enterprising Los Angeles importer renamed it the considerably more palatable "Chilean sea bass.”

“The researchers found that nearly every change they made was followed by a temporary uptick in performance, even when it involved simply undoing a previous change. They concluded that the increases in worker productivity were not due to better lighting or better pay or longer breaks per se. They were just temporary improvements caused by a change in routine.”

“The world isn't black and white, Annie, it's shades of grey.”

“Look into the eyes of a chicken and you will see real stupidity. It is a kind of bottomless stupidity, a fiendish stupidity. They are the most horrifying, cannibalistic and nightmarish creatures in the world.”

“A ship with two of every animal in the world, my friend? That would have to be a very large ship indeed. Is that how you would save a world? A bull and a cow, a sheep and a ram, and so on? The people who wrote your Torah, my friend, must have had poor livestock if they raised their herds from only one dam and one sire, breeding sisters with their brothers, any herdsman knows that this does not produce a healthy flock.No, my friend to save the world you save the knowledge of that world, the knowledge that there were bulls and cows in it, that there were sheep and rams in it, that there were men and women who lived and died. If your world is to be destroyed, all you can save my friend, is the knowledge of it, to restore what you once had, to mourn what can never be restored.”
