Listen to me, my friend. Hope is a dangerous thing. Hope can make people crazy.

The unexamined life is not worth living.

I prefer liberty with danger to peace with slavery.

The ideas of economists and political philosophers， both when they are right and when they are wrong， are more powerful than is commonly understood. Indeed the world is ruled by little else. Practical men， who believe themselves to be quite exempt from any intellectual influence， are usually the slaves of some defunct economist.

 释义：贫穷和地位低下不是什么耻辱的事，但因为贫穷和地位低下而向他人谄媚奉承，乞求得到施舍，就真是耻辱。

【译文】 粮食尽量精，肉类尽量细。变质的东西不吃；变色的东西不吃，变味的东西不吃；烹饪得不好不吃；不是吃饭的时间不吃；切的不好看不吃；调味品不好不吃。肉类虽多，但不要吃过量。只有酒不限量，但不要喝醉。从集市上买来的酒肉不吃；每餐必有姜，但不多吃。
