A huge part of culture is the painting of a particular degree or kind of foolishness as wisdom, by at least the vast majority of a particular group of fools … or mostly fools.

Some people are wise only when they are in public.

As if their not being smart were not unfortunate enough, most people think they are smart.

Pretending to be wise is way more difficult than pretending not to be a fool.

One of the most common and most dangerous misbeliefs is that it is impossible for someone to be stupid just because they are a doctor or a lawyer.

To be ashamed of being poor, you need, not only poverty, but also stupidity.

We sometimes pretend to agree with a statement, as an attempt to hide the fact that we are not smart enough to understand it.

You can know a lot and still be stupid.

Being patient with a fool requires one not to be one.
