「見其生，不忍見其死；聞其聲，不忍食其肉。」
孟子
「人一殺生，則五常盡犯焉。蓋屠戮他身，肥甘自己，為不仁也；離他眷屬，延我親朋，為不義也；將他肉體，供獻神人，為不禮也；稱言食祿，當受刀砧，為不智也；設餌妝媒，引入陷阱，為不信也。噫！人居塵世，全藉五常，知而故犯，又何足為人？」
蘇軾
「夫素食為延年益壽之妙術，已為今日科學家、衛生家、生理學家、醫學家所共認矣，而中國人之素食，尤為適宜。」
孫中山
“Animals are my friends... and I don't eat my friends.”
George Bernard Shaw
“The greatness of a nation and its moral progress can be judged by the way its animals are treated.”
Mahatma Gandhi
"If slaughterhouses had glass walls, everyone would be vegetarian."
Paul McCartney
"For as long as man continues to be the ruthless destroyer of lower living beings, he will never know health or peace. For as long as men massacre animals, they will kill each other. Indeed, he who sows the seeds of murder and pain cannot reap joy and love."
Pythagoras
"The question is not, can they reason? Nor can they talk? But, can they suffer?"
Jeremy Bentham
"The world is not a piece of machinery and animals are not articles manufactured for our use."
Arthur Schopenhauer
"Truly man is the king of beasts, for his brutality exceeds theirs. We live by the death of others: We are burial places!"
Leonardo da Vinci
“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
"Now I can look at you in peace; I don't eat you any more."
Franz Kafka
“Until we boycott meat, and all other products of animal factories, we are, each one of us, contributing to the continued existence, prosperity, and growth of factory farming and all the other cruel practices used in rearing animals for food.”
Peter Singer
"Every time you spend money, you’re casting a vote for the kind of world you want."
