“If children were brought into the world by an act of pure reason alone, would the human race continue to exist? Would not a man rather have so much sympathy with the coming generation as to spare it the burden of existence, or at any rate not take it upon himself to impose that burden upon it in cold blood?”
― Arthur Schopenhauer, Studies in Pessimism: The Essays

“Compassion for animals is intimately associated with goodness of character, and it may be confidently asserted that he who is cruel to animals cannot be a good man.”
― Arthur Schopenhauer, The Basis of Morality

“It would be better if there were nothing. Since there is more pain than pleasure on earth, every satisfaction is only transitory, creating new desires and new distresses, and the agony of the devoured animal is always far greater than the pleasure of the devourer.”
― Arthur Schopenhauer

“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
