Politics have always covered two distinct kinds of problems: problems of administrative routine, and those that may be called 'questions of the moment.' A question of the moment is, indeed, a substitute for some notion, such as the idea of God, or hereditary monarchy, or national glory, that has hitherto acted as a symbol of human co-ordination. It provides no new positive certainty to replace the discredited certainty, but is what the name implies: the raising of a question which the old certainty no longer answers.
