"What I had learned about human rights proved to be directly relevant to my thinking about animal rights. Whether any animals have rights depends on the true answer to one question: Are any animals subjects-of-a-life? This is the question that needs to be asked about animals because this is the question we need to ask about us."

“The task facing ARAs is daunting: we must empty the cages, not make them larger.”

“Finally, and lamentably, one thing seems certain. Unless the massive amount of violence done to animals is acknowledged by those who do it, and until meaningful steps are taken to end it, as certain as night follows day, some ARAs, somewhere, somehow, will use violence against animal abusers themselves to defend the rights of animals.”

“People like me, people who believe in animal rights, feel the same way about eagles and elephants, pigs and porpoises, as most people feel about cats and dogs. Don't get me wrong. Animal Rights Advocates don't want pigs sleeping in our beds or elephants riding in our cars. We don't want to make “pets” of these animals. What we want is something simpler: we just want people to stop doing terrible things to them.”

“I would never have become an animal rights advocate if I had not first been a human rights advocate, especially for those humans who lack the understanding or power to assert their rights for themselves.”

“From my reading of Gandhi I had learned how some people in India regard eating cow as unspeakably repulsive. I realized I felt the same way about cats and dogs: I could never eat them. Were cows so different from cats and dogs that there were two moral standards, one that applies to cows, another that applies to cats and dogs? Were pigs so different? Were any of the animals I ate so different?”

“Then there are those proverbial “bird brains” of the barnyard, chickens, surely the most maligned and abused animal on the face of the earth, and—just as surely—among the brightest, most social birds we'll find anywhere. … Chickens not only are capable of learning, they are also capable of teaching one another. It turns out that chickens are not as dumb as popular mythology makes them out to be.”
