The birthmark which we have noted on Plato is an inheritance from unreasoning hatred of democracy. That which mars above all the political thinking of Aristotle comes from the aversion instinctively felt by his age for imperialism. That this, too, is a disfigurement, we may show in a few concluding remarks. "It is necessary," says Aristotle[57] in concluding his plea that a mixed constitution is best for the common run of states, "it is necessary to begin by assuming a principle of general application, viz., that the part of the state which desires the continuance of the polity ought to be stronger than that which does not"; and he proceeds to point out that "strength" consists neither in numbers, nor property, nor military or political ability alone, but in all of them combined, so that regard has to be taken of "freedom, wealth, culture, and nobility, as well as of mere numerical superiority." Nothing could be more cold and objective than the thinking of Aristotle on this important matter. Yet by an extraordinary oversight he lets "strength" exert a decisive influence _within_ the city-states, while he ignores altogether the effect of varying population, wealth, and political and military ability in determining the relations _between_ them. The whole of the political thinking of Aristotle is dominated by the idea that the world of men is made up of an infinite procession of inferiors and superiors, the desire to forge ahead being one of the most fundamental instincts of human beings. If an omniscient God were to arrange the inhabitants of each city in a line according to their real "strength," he would place few of them abreast. No Greek betrays more naïvely than Aristotle does the national consciousness of the Hellenes that they stood at the head of the honor roll of peoples. It was, therefore, imperative upon them to conquer the Asiatics; for he finds it to be a beneficent command of nature, issued primarily for the advantage of the weaker, that superiors should rule inferiors. Among moral philosophers Aristotle is characterized by his refusal to let himself be led astray by a visionary ideal of human equality. Nevertheless, while recognizing that Greek cities, even more than individuals, differed in "strength," he refused to let the "strong" use their advantage. He sets apart the sphere of interurban, that is to say, international, relations as one in which the "universal principle," that superior rule inferior, shall not apply. In a visionary world, the "strong" man, on Aristotle's theory, is a "gentle" man; but in the real world, he is a ruler. Had Aristotle not been blinded by the prejudices of his age against imperialism, he must have seen the necessity that in the real world the "strong" state would also be the ruler. It is one of the enigmas of history that Aristotle was the contemporary and subject of Philip II of Macedon, one of its ironies that he was the tutor of Alexander the Great. SELECT BIBLIOGRAPHY
