Not everyone who talks less or keeps quiet whenever they are with or around you does that because they find you interesting or knowledgeable; some people do that because they find you boring or ignorant.

An ignorant man who is regarded as knowledgeable by people who are more ignorant than him is still ignorant.

Most unintelligent or foolish people do not regard themselves as that; they regard themselves as not-that-intelligent or not-that-wise.

The kind of lies that someone tells us gives us an idea of how stupid, knowledgeable, intelligent, or ignorant they are … or they think we are.

The arrogant generally deem the humble ignorant.

You can know a lot and still be stupid.

Our choice of words often reveal the depth of our knowledge … or ignorance … or that of our desire to be deemed knowledgeable.
