It is difficult to be enthusiastic about Aristotle, because it was difficult for him to be enthusiastic about anything... He realized too completely the Delphic command to avoid excess: he is so anxious to pare away extremes that at last nothing is left. He is so fearful of disorder that he forgets to be fearful of slavery; he.is so timid of uncertain change that he prefers a certain changelessness that near resembles death. He lacks that Heraclitean sense of flux which justifies the conservative in believing that all permanent change is gradual, and justifies the radical in believing that no changelessness is permanent. He forgets that Plato's communism was meant only for the elite, the unselfish and ungreedy few; and he comes deviously to a Platonic result when he says that though property should be private, its use should be as far as possible common. He does not see (and perhaps he could not be expected in his early day to see) that individual control of the means of production was stimulating and salutary only when these means were so simple as to be purchasable by any man; and that their increasing complexity and cost lead to a dangerous centralization of ownership and power, and to an artificial and finally disruptive inequality.
