Stupidity

Any fool can critizise, condemn and complain – and most fools do

When a stupid man is doing something he is ashamed of, he always declares that it is his duty

A wise man gets more use from his enemies than a fool from his friends

Better to keep your mouth shut and appear stupid than to open it and remove all doubt

Only two things are infinite, the universe and human stupidity, and I’m not sure about the former

Man is the most intelligent of the animals - and the most silly

The greatest of follies is to sacrifice health for any other kind of happiness
