A metaphysic, held by the rulers with the force of a religion, is a bad sign. It forbids them, like the inquisitor, to admit any grain of truth or good in their opponents, it abrogates the ordinary rules of morality, and it gives a seemingly high, super-personal sanction to all the very ordinary human passions by which, like other men, the rulers will frequently be actuated. In a word, it forbids wholesome doubt. A political programme can never in reality be more than probably right. We never know all the facts about the present and we can only guess the future. To attach to a party programmeâwhose highest real claim is to reasonable prudenceâthe sort of assent which we should reserve for demonstrable theorems, is a kind of intoxication.
C.S. Lewis, A Reply to Professor Haldane
