"The professional and financial interest in continuing animal experimentation helps to explain at least some resistance to the notion that animals have a complex emotional life and are capable of experiencing the higher emotions, such as love, compassion, altruism, disappointment and nostalgia. To acknowledge such a possibility implies certain moral obligations. If chimpanzees can experience loneliness and mental anguish, it becomes more wrong to use them for experiments in which they are isolated and anticipate daily pain."

“There are many people who have undergone great suffering who seem to possess knowledge of the deepest recesses of human emotion unavailable to the rest of us. They may want to impart it, but we often cannot hear. Strangely enough, farm animals strike me in the same way.”

“Almost all analysts in America are physicians and psychiatrists, and the medical profession is layered into a strict hierarchy. Every psychiatrist in a hospital is chief of some service, or head of some department.”

“The cat does not merely experience contentment, he exudes it. You cannot be in the presence of a contented cat and not have some of that contentment rub off on you. Which surely is a good part of the reason we love cats so.”

“Perhaps it is possible for humans to change directions, to look at animals not as competitors or as yet another race to colonize, but as models for achieving something that has eluded humans for their entire evolutionary history. If animals can learn to live with other species in peace, and sometimes even in friendship, is it not possible that observing this extraordinary ability may yet act as a catalyst for us? Is it not possible that harmony among nations need be not a mere fantasy, but something we can learn from observing the achievements of these so-called lesser species? All that is lacking are the will and the humility.”

“Because I was so eager to believe I was being helped by a talented, ethical, benevolent, and intelligent man, I sought evidence for this wherever I could. Anything less than this was too dreadful to contemplate.”

“I still yearned then, and probably even more so earlier, for a strong, masculine person on whom I could pattern myself. Somebody I could admire, and imitate, and become close to and learn from. I had sought this, always, in my teachers, and my search had always ended in disappointment. I was attracted emotionally to a position that I could only despise intellectually.”
