Pareto isn't interested in the nature of politics but in the political society and in its equilibrium. The method he finally adopted, after some hesitations, is the one he tested in his economical and sociological research work. Analysing the changing of the elites, he stresses the importance of the minority that is in power. However the decline of an oligarchy is always concomitant with the coming up of another one. As far as Pareto's personal political stand is concerned he was neither a fascist nor a democrat but a liberal. This is revealed by a careful analysis of his works, from the first to the last of his writings.
