As long as man continues to be the ruthless destroyer of lower living beings, he will never know health or peace. For as long as men massacre animals, they will kill each other.
只要人类继续无情地摧毁较低级的生命，他们永远不会知道健康和和平。因为只要人类屠杀动物，他们也会相互杀戮。
最大的智慧在于简单。
物质的唯一法则是由我们的心灵所构建的，而心灵的唯一法则是由物质为它构建的。
Reputation is what other people know about you. Honor is what you know about yourself.
"The joy of discovery is certainly the liveliest that the mind of man can ever feel."
