“If you took the city of Tokyo and turned it upside down and shook it you would be amazed at the animals that fall out: badgers, wolves, boa constrictors, crocodiles, ostriches, baboons, capybaras, wild boars, leopards, manatees, ruminants, in untold numbers. There is no doubt in my mind that that feral giraffes and feral hippos have been living in Tokyo for generations without seeing a soul.”

“What don’t we realize is that we are a strange and forbidding species to wild animals. We fill them with fear. They avoid us as much as possible. It took centuries to still the fear in some pliable animals – domestication it’s called – but most cannot get over their fear, and I doubt they ever will. When wild animals fight us, it is out of sheer desperation. They fight when they feel they have no other way out.”

“It begins in your mind, always. One moment you are feeling calm, self-possessed, happy. Then fear, disguised in the garb of mild-mannered doubt, slips into your mind like a spy. Doubt meets disbelief and disbelief tries to push it out. But disbelief is a poorly armed foot soldier. Doubt does away with with little trouble. You become anxious. Reason comes to do battle for you. You are reassured. Reason is fully equipped with the latest weapons technology. But, to your amazement, despite superior tactics and a number of undeniable victories, reason is laid low. you feel yourself weakening, wavering. Your anxiety becomes dread. ”

“One might even argue that if an animal could choose with intelligence, it would opt for living in a zoo, since the major difference between a zoo and the wild is the absence of parasites and enemies and the abundance of food in the first, and their respective abundance and scarcity in the second. Think about it yourself. Would you rather be put up at the Ritz with free room service and unlimited access to a doctor or be homeless without a soul to care for you?...But I don't insist. I don't mean to defend zoos. Close them all down if you want (and let us hope that what wildlife remains can survive in what is left of the natural world). I know zoos are no longer in people's good graces. Religion faces the same problem. Certain illusions about freedom plague them both.”

“I quite deliberately dressed wild animals in tame costumes of my imagination.”

“If you went to a home, kicked down the front door, chased the people who lived there out into the street and said, "Go! You are free! Free as a bird! Go! Go!" -- do you think they would shout and dance for joy? They wouldn't. Birds are not free. The people you've just evicted would sputter, "With what right do you throw us out? This is our home. We own it. We have lived here for years. We're calling the police, you scoundrel.”

“The three-toed sloth lives a peaceful, vegetarian life in perfect harmony with its environment. A good-natured smile is forever on its lips...I have seen that smile with my own eyes. I am not one given to projecting human traits and emotions onto animals, but many a time during that month in Brazil, looking up at a sloth in repose, I felt I was in the presence of upside-down yogis deep in meditation or hermits deep in prayer, wise beings whose intense imaginative lives were beyond the reach of scientific probing.”
