It is better to be a human being dissatisfied than a pig satisfied; better to be Socrates dissatisfied than a fool satisfied.

It is better to be a human being dissatisfied than a pig satisfied; better to be Socrates dissatisfied than a fool satisfied.

做人不知足，强如猪知足;宁为苏格拉底不满意，不为傻瓜满意。

-- John Stuart Mill 约翰·斯图尔特·密尔
