In Return, He Owes It To His Fellow Men (or 'to Society') To Represent The Results Of His Study As Simply, Clearly And Modestly As He Can. The Worst Thing That Intellectuals Can Do - The Cardinal Sin - Is To Try To Set Themselves Up As Great Prophets Vis-à-vis Their Fellow Men And To Impress Them With Puzzling Philosophies. Anyone Who Cannot Speak Simply And Clearly Should Say Nothing And Continue To Work Until He Can Do So.
