Sofi

“A man can live and be healthy without killing animals for food; therefore, if he eats meat, he participates in taking animal life merely for the sake of his appetite. And to act so is immoral.”
― Leo Tolstoy

“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.”
― Arthur Schopenhauer, The Basis of Morality

“The question is not, "Can they reason?" nor, "Can they talk?" but "Can they suffer?”
― Jeremy Bentham (An Introduction to the Principles of Morals and Legislation (Philosophical Classics), The Principles of Morals and Legislation

“People often say that humans have always eaten animals, as if this is a justification for continuing the practice. According to this logic, we should not try to prevent people from murdering other people, since this has also been done since the earliest of times.”
― Isaac Bashevis Singer
