“In zoos, along with the animals, the humanity of man is also prisoned! No cage is humane!”

“And people who believe in God think God has put human beings on earth because they think human beings are the best animal, but human beings are just an animal and they will evolve into another animal, and that animal will be cleverer and it will put human beings into a zoo, like we put chimpanzees and gorillas into a zoo. Or human beings will all catch a disease and die out or they will make too much pollution and kill themselves, and then there will only be insects in the world and they will be the best animal.”

“A good zoo," Stella said, "is a large domain. A wild cage. A safe place to be. It has room to roam and humans who don't hurt." She pauses, considering her words. "A good zoo is how humans make amends.”

“The caged eagle become a metaphor for all forms of isolation, the ultimate in imprisonment. A zoo is prison.”

“Zoos are full, prisons are overflowing. Ah, my. How the world still dearly loves a cage.”

“You think human nature is a beast, that it must be put in a cage. But it's the cage that makes the animal bad.”
