The pluralists reject the distinction, which is so neatly made, between the State and government. They insist on a realistic Political Science and consider the distinction between the two as an artificial product of legal reasoning and slogical refinement. Duguit is the foremost in this respect. He asserts that juristic entities, being legal fictions, have no place in realistic as distinguished from metaphysical discussion. We only know the government as a matter of reality and as it functions actually. The immediate power belongs to the government and the State and government are in fact the same. Laski also speaks of the State as the government and he rejects. likewise, the legalistic theory of the personality of the State. American political scientists substitute the State by a political system which in itself is a unit of the social system. Robert Dahl says that almost every human association has a political system and he even includes families in his definition of a political system.
