Yes. Trump takes the prize for egotism and — I would argue — ignorance. Writing in the 19th century, Horace Mann described men like Trump with eerie precision:
“The most ignorant are the most conceited. Unless a man knows that there is something more to be known, his inference is, of course, that he knows everything.
“Such a man always usurps the throne of universal knowledge, and assumes the right of deciding all possible questions. We all know that a conceited dunce will decide questions extemporaneous which would puzzle a college of philosophers, or a bench of judges. Ignorant and shallow-minded men do not see far enough to see the difficulty….
“And for all purposes of individual character, as well as of social usefulness, it is quite as important for a man to know the extent of his own ignorance as it is to know anything else.
“To know how much there is that we do not know, is one of the most valuable parts of our attainments; for such knowledge becomes both a lesson of humility and a stimulus to exertion.”
