“To give preference to the life of a being simply because that being is a member of our species would put us in the same position as racists who give preference to those who are members of their race.”

“Hebrew word for "charity" tzedakah, simply means "justice" and as this suggests, for Jews, giving to the poor is no optional extra but an essential part of living a just life.”

“In an earlier stage of our development most human groups held to a tribal ethic. Members of the tribe were protected, but people of other tribes could be robbed or killed as one pleased. Gradually the circle of protection expanded, but as recently as 150 years ago we did not include blacks. So African human beings could be captured, shipped to America, and sold. In Australia white settlers regarded Aborigines as a pest and hunted them down, much as kangaroos are hunted down today. Just as we have progressed beyond the blatantly racist ethic of the era of slavery and colonialism, so we must now progress beyond the speciesist ethic of the era of factory farming, of the use of animals as mere research tools, of whaling, seal hunting, kangaroo slaughter, and the destruction of wilderness. We must take the final step in expanding the circle of ethics. -”

“Were we incapable of empathy – of putting ourselves in the position of others and seeing that their suffering is like our own – then ethical reasoning would lead nowhere. If emotion without reason is blind, then reason without emotion is impotent.”

“Forests and meat animals compete for the same land. The prodigious appetite of the affluent nations for meat means that agribusiness can pay more than those who want to preserve or restore the forest. We are, quite literally, gambling with the future of our planet – for the sake of hamburgers”

“If morality is always relative to one’s own society, then you, coming from your society, have your moral standards and I, coming from my society, have mine. It follows that when I criticize your moral standards, I am simply expressing the morality of my society, but it also follows that when you condemn me for criticizing the moral standards of your society, you are simply expressing the morality of your society. There is, on this view, no way of moving outside the morality of one’s own society and expressing a transcultural or objective moral judgment about anything, including respect for the cultures of different peoples. Hence if we happen to live in a culture that honors those who subdue other societies and suppress their cultures, then that is our morality, and the relativist can offer no cogent reason why we should not simply get on with it.”

“In the past 20 years alone, it adds up to more death than were caused by all the civil and international wars adn government repression of the entire twentieth century, the century of Hitler and Stalin. How much would we give to prevent those horrors? Yet how little are we doing to prevent today's even larger toll and all the misery that it involves? I believe that if you read this book to the end, and look honestly and carefully at our situation, assessing both the facts and the ethical arguments, you will agree that we must act.”
