I had a professor of modern literature in college who was a self-professed “Hemingway expert”. I’m not much for self-professed experts in anything and this old coot certainly rubbed me the wrong way. His lectures were interminable. He droned on in perfect monotone as students dropped off to sleep across the class. He began the year by telling each of us, in his earnest tweedy professor way, that there were no rights or wrongs in his class. Opinions were what counted. You would be graded on how well you expressed them.
