Until we have courage to recognize cruelty for what it is - whether its victim is human or animal - we cannot expect things to be much better in the world. There can be no double standard. We cannot have peace among men whose hearts find delight in killing any living creature. By every act that glorifies or even tolerates such moronic delight in killing, we set back the progress of humanity.

We still talk in terms of conquest. We still haven't become mature enough to think of ourselves as only a tiny part of a vast and incredible universe. Man's attitude toward nature is today critically important simply because we have now acquired a fateful power to alter and destroy nature. But man is a part of nature, and his war against nature is inevitably a war against himself.

We cannot have peace among men whose hearts find delight in killing any living creature.
