There are four mental types
among human beings.
The man who knows,
and is aware that he knows:
he is wise, so inquire of him.
The man who knows,
but is unaware that he knows:
remind him and help him that he forget not.
The man who is ignorant,
and knows that he is ignorant : teach him.
The man who is ignorant,
but pretends to know:
he is fool, so keep away from him.
人有四種思維:
有學識之人,并能認識到自己是有學問的:
他是明智的,向這種人請教吧;
有學識但卻意識不到自己有學識:
提醒并幫助他,讓他不忘記。
無知之人,但有自知之明:幫他一把吧。
愚昧之人,但卻不懂裝懂:那是一個笨蛋,離他遠點。
