Lewis, on Bulverism

Concerning Ezekiel Bulver, an imaginary character, Lewis writes, "whose destiny was determined at the age of five when he heard his mother say to his father—who had been maintaining two sides of a triangle were together greater than the third—'Oh you say that because you are a man.' 'At that moment' E. Bulver assures us, 'there flashed across my opening mind the great truth that refutation is no necessary part of an argument. Assume that your opponent is wrong, and then explain his error, and the world will be at your feet.'" Cited in Alan Jacobs, The Narnian, 196.
