“Everything that motivates living creatures is based onsome weakness or flaw. Hunger motivates animals. Lustmotivates animals. Fear and pain motivate animals. A Godwould have none of those impulses. Humans are driven byall of our animal passions plus loftier-sounding things likeself-actualization and creativity and freedom and love”

“Though reason must guide us in laying down standards and laws regarding animals, and in examining the arguments of those who reject such standards, it is usually best in any moral inquiry to start with the original motivation, which in the case of animals we may without embarrassment call love. Human beings love animals as only the higher love the lower, the knowing love the innocent, and the strong love the vulnerable. When we wince at the suffering of animals, that feeling speaks well of us even when we ignore it, and those who dismiss love for our fellow creatures as mere sentimentality overlook a good and important part of our humanity.”

“You can motivate by fear, and you can motivate by reward. But both those methods are only temporary. The only lasting thing is self motivation.”

“Poetry is the sound of the human animal.”

“If you believe that humans are animals, there can be no such thing as the history of humanity, only the lives of particular humans. If we speak of the history of the species at all, it is only to signify the unknowable sum of these lives. As with other animals, some lives are happy, others wretched. None has a meaning that lies beyond itself.”

“I believe that the best way to create good living conditions for any animal, whether it's a captive animal living in a zoo, a farm animal or a pet, is to base animal welfare programs on the core emotion systems in the brain. My theory is that the environment animals live in should activate their positive emotions as much as possible, and not activate their negative emotions any more than necessary. If we get the animal's emotions rights, we will have fewer problem behaviors... All animals and people have the same core emotion systems in the brain.”
