Some nice quotes from some notable names.
George Bernard Shaw: "Animals are my friends..and I don't eat my friends."
Thomas Edison: "Non-violence leads to the highest ethics, which is the goal of all evolution. Until we stop harming all other living beings, we are still savages."
Da Vinci: "I have from an early age abjured the use of meat, and the time will come when men such as I will look upon the murder of animals as they now look upon the murder of men."
Gandhi: "Ethically they had arrived at the conclusion that man's supremacy over lower animals meant not that the former should prey upon the latter, but that the higher should protect the lower, and that there should be mutual aid between the two as between man and man. They had also brought out the truth that man eats not for enjoyment but to live."
Benjamin Franklin: "My refusing to eat meat occasioned inconveniency, and I have been frequently chided for my singularity. But my light repast allows for greater progress, for greater clearness of head and quicker comprehension."
Charles Darwin: "There is no fundamental difference between man and the higher animals in their mental faculties . . . The lower animals, like man, manifestly feel pleasure and pain, happiness, and misery."
Leo Tolstoy: "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."
Mark Twain: "Of all the creatures, man is the most detestable. Of the entire brood, he’s the one that possesses malice. He is the only creature that inflicts pain for sport, knowing it to be pain. The fact that man knows right from wrong proves his intellectual superiority to the other creatures; but the fact that he can do wrong proves his moral inferiority to any creature that cannot."
