Brains are delicate things…
“All men are intellectuals… but not all men play the intellectuals’ role in the society.” Tony Gramsci
“An intellectual is someone who can hear the William Tell Overture without thinking of the Lone Ranger.”
Let’s face it, there are some dense and narrow and frankly obedient PhDs and professors out there. You can have all the badges of merit that academia can produce but still be, well, stupid.
So, does having a high IQ mean you are an intellectual? No, IQ tests were systematically rigged to leave white middle-class males on top. I would say that an intellectual is someone who is willing to ask questions, and figure out ways of arriving at reliable answers.
