动物伦理的限度

素食主义、动物保护主义禁不起理性的追问。关于杀生的伦理原则，应该是把需求量降到最低，把猎杀量降到最低。为了人类的生存和健康，我们不得不杀生，那是我们不得不作的恶。必要的作恶不算作恶，理性的作恶恶中有善。因为并不是每一个生命都有生长的权利，大部分物种的繁衍能力都远远超出其维持种群常数的需要，这超出的部分，就是提供给在食物链上居于其上一级的物种食用的。

The Limits of Animal Ethics

Vegetarian principles and animal protectionism fail to stand rational interrogation. As regards the ethic principle of animal slaughter, the demand for and the number of slaughtered animals should be minimized; but for the survival and health of human beings, we have to slaughter animals, which is the evil we have to do; and necessary evils done by mankind are not, however, evils; for there is good in rational evils. Not every life is entitled to growth in that the fertility of most species are far beyond the need for sustaining their respective constant number, and the superfluous numbers of the species are to be preyed upon by animals of a higher level along the food chain.
