If man wants freedom why keep birds and animals in cages? Truly man is the king of beasts, for his brutality exceeds them. We live by the death of others. We are burial places! I have from an early age abjured the use of meat, and the time will come when men such as I look upon the murder of animals as they now look upon the murder of men.
---- Leonardo da Vinci
人的确是万兽之王,他的残暴胜于所有的动物。我们靠其他生灵的死而生活,我们都是坟墓。我在很小的时候就发誓再也不吃肉了。总有一天,人们将视杀生如同杀人。
—达芬奇(Leonardo da Vinci)
