Here again C. S. Lewis comes to our aid. In a comical passage from a serious essay, he imagines one Ezekiel Bulver, “one of the makers of the Twentieth Century,” whose great achievement was the uncovering of this great and lasting truth: “Assume that your opponent is wrong, and then explain his error, and the world will be at your feet. Attempt to prove that he is wrong or (worse still) try to find out whether he is wrong or right, and the national dynamism of our age will thrust you to the wall.”
