How to correctly interpret a judgment about a person's mind?
"A fool thinks that he is clever; a clever man knows that he is stupid" – this or something like this phrase I have already met several times in the books of E. Fromm and in other literature, and I had a logical question.Let's say I say I know I'm stupid. But when I say I'm stupid, I mean I know I'm smart, and if I know I'm smart, then I'm stupid. And it would be fine if the judgment here looped further (I am stupid, which means I am smart, which means I am stupid, etc.), but this does not happen, because in order to be called stupid, I must be smart, but the statement about my stupidity comes out as if from outside, that is, I no longer control it with my judgment.So questions arise:In any case further reasoning I will have to come to the conclusion that I am stupid? Or does the phrase imply no further reasoning? Am I misinterpreting this judgment?
