" If, of course, there is neither freedom nor any moral law based on freedom, but only a state in which everything that happens or can happen simply obeys the mechanical workings of nature, politics would mean the art of utilising nature for the government of men, and this would constitute the whole of practical wisdom; the concept of right would then be only an empty idea. But if we consider it absolutely necessary to couple the concept of right with politics, or even to make it a limiting condition of politics, it must be conceded that the two are compatible. And I can indeed imagine a moral politician, i.e. someone who conceives of the principles of political expediency in such a way that they can co-exist with morality, but I cannot imagine a political moralist, i.e. one who fashions his morality to suit his own advantage as a statesman. "
