If there are no stupid questions, then what kind of questions do stupid people ask? Do they get smart just in time to ask questions.
There are three kinds of intelligence: one kind understands things for itself, the other appreciates what others can understand, the third understands neither for itself nor through others. This first is excellent, the second good, and the third useless.
I don't think there's anything unique about human intellience. All the nuerons in the brain that make up perceptions and emotions operate in a binary fashion.
The intellect is not a serious thing, and never has been. It is an instrument on which one plays, that is all.
