Within long spans of human progress it may occasionally happen that the practical politician and political philosopher are one. The more intimate this union is, the greater will be the obstacles which the activity of the politician will have to encounter. Such a man does not labour for the purpose of satisfying demands that are obvious to every philistine, but he reaches out towards ends which can be understood only by the few. His life is torn asunder by hatred and love. The protest of his contemporaries, who do not understand the man, is in conflict with the recognition of posterity, for whom he also works.
