That bit about the validity of the quote was just an afterthought, the first 2 quotes attack the premise of the quote directly. Everybody CANNOT be a genius. A genius, by definition, is someone who excels, who is at the far end of the bell curve. We cannot ALL excel, otherwise the word loses it's meaning. Also, the point isn't whether someone 'feels" stupid or not, it's if he really "is" stupid, right? (Besides, self-esteem has been proven not to have a connection with intelligence, I think it's also mentioned in Carlin's video.)Sorry for my bad English. (...but why are we talking in English?)
