When someone disagrees with you on a moral point you assume that he is one step behind in his thinking, and he assumes that he has gone one step ahead. But I take both parts, O'Hara, leapfrogging myself along the great moral issues, refuting myself and rebutting the refutation towards a truth that must be the compound of two opposite half-truths. And you never reach it because there is always something more to say.
Tom Stoppard
