“Compassion is the basis of morality.”
“universal compassion is the only guarantee of morality.”
“The assumption that animals are without rights and the illusion that our treatment of them has no moral significance is a positively outrageous example of Western crudity and barbarity. Universal compassion is the only guarantee of morality.”
“Consider the Koran, for example; this wretched book was sufficient to start a world-religion, to satisfy the metaphysical needs of countless millions for twelve hundred years, to become the basis of their morality and of a remarkable contempt for death, and also to inspire them to bloody wars and the most extensive conquests.
