I am surrounded by idiots.
But everyone thinks that.
If you're an idiot, your definition of an idiot is anyone who disagrees with you. Seeing as that's pretty much everyone, they surrond you.
If you're not an idiot, your definition of an idiot is anyone who can't bear to think they might be wrong, misguided, or not respected. Seeing as that's pretty much everyone, they surround you.
The difference between an idiot and a fool is that a fool accepts all criticisms unquestioningly, while an idiot accepts none.
So if you're wondering whether you're an idiot, imagine someone calling you an idiot. If your response is to consider that they might be right, you know they're wrong.
But if you're wondering, you're already not an idiot, because idiots can't endure introspection - because that's a form of (self) criticism.
The result of educating an idiot is an educated idiot.
If you can list ten arguments against a belief which is important to you, you're educated. If they're all strawmen, you're still an idiot.
Idiocy is not a failure of intellect but of courage.
