It is evident, then, that Aristotle cannot be approached with the same perfect dispassionateness as the other great thinkers of antiquity. He is, if not a living force, still a force which must be reckoned with in contemporary controversy. His admirers persist in making an authority of him, or at least of quoting him in behalf of their own favourite convictions. We are, therefore, bound to sift his claims with a severity which would not be altogether gracious in a purely historical review. At the same time it is hoped that historical justice will not lose, but gain, by such a procedure. We shall be the better able to understand what Aristotle was, after first showing what he neither was nor could be. And the utility of our investigations will be still further enhanced if we can show that he represents a fixed type regularly recurring in the revolutions of thought. II. Personally, we know more about Aristotle than about any other Greek philosopher of the classic period; but what we know does not amount to much. It is little more than the skeleton of a life, a bald enumeration of names and dates and places, with a few more or less doubtful anecdotes interspersed. These we shall now relate, together with whatever inferences the facts seem to warrant. Aristotle was born 384 B.C., at Stageira, a Greek colony in Thrace. It is remarkable that every single Greek thinker of note, Socrates and Plato alone excepted, came from the confines of Hellenedom and barbarism. It has been conjectured by Auguste Comte, we know not with how much reason, that religious traditions were weaker in the colonies than in the parent states, and thus allowed freer play to independent speculation. Perhaps, also, the accumulation of wealth was more rapid, thus affording greater leisure for thought; while the pettiness of political life liberated a fund of intellectual energy, which in more powerful communities might have been devoted to the service of the State. Left an orphan in early youth, Aristotle was brought up by one Proxenus, to whose son, Nicanor, he afterwards repaid the debt of gratitude. In his eighteenth year he settled at Athens, and attended the school of Plato until the death of that philosopher twenty years afterwards. It is not clear whether the younger thinker was quite conscious of his vast intellectual debt to the elder, and he continually emphasises the points on which they differ; but personally his feeling towards the master was one of deep reverence and affection. In some beautiful lines, still extant, he speaks of ‘an altar of solemn friendship dedicated to one of whom the bad should not speak even in praise; who alone, or who first among mortals, proved by his own life and by his system, that goodness and happiness go hand in hand;’ and it is generally agreed that the reference can only be to Plato. Again, in his _Ethics_, Aristotle expresses reluctance to criticise the ideal theory, because it was held by dear friends of his own; adding the
