The reason why men enter into society is the preservation of their property.

 释义：不和他人去争名利上的得与失，只求自己能够拥有和增长智慧与才干。

如果不改善个人，就无法希望建立一个更美好的世界。为此，我们每个人都必须为自己的进步而努力，同时为全人类承担共同的责任。

Society can and does execute its own mandates， and if it issues wrong mandates instead of right， or any mandates at all in things with which it ought not to meddle， it practices a social tyranny more formidable than many kinds of political oppression， since， though not usually upheld by such extreme penalties， it leaves fewer means of escape， penetrating much more deeply into the details of life， and enslaving the soul itself.
