독일 철학자 (1788-1860)
“Since compassion for animals is so intimately associated with goodness of character, it may be confidently asserted that whoever is cruel to animals cannot be a good man.”
"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."
