One other thing besides the conflicts of the time perhaps stimulated the mind of Plato in this direction. In the days of Pericles Athens had founded many settlements overseas, and the setting up of these settlements had familiarized men with the idea that a community need not grow, it could also be made.
Closely associated with Plato was a younger man, who later also maintained a school in Athens and lived to an even greater age. This was Isocrates. He was what we should call a publicist, a writer rather than an orator, and his peculiar work was to develop the idea of Herodotus, the idea of a unification of Greece against the Persian Empire, as a remedy for the baseness and confusion of her politics and the waste and destruction of her internecine wars. His political horizon was in some respects broader than Plato’s, and in his later years he looked towards monarchy, and particularly towards the Macedonian monarchy of Philip, as a more unifying and broadening method of government than city democracy. The same drift to monarchist ideas had occurred in the case of that Xenophon whose Anabasis we have already mentioned. In his old age this retired mercenary wrote the Cyropædia, a “vindication both theoretically and practically of absolute monarchy as shown in the organization of the Persian Empire.”[188]
§ 6
Plato taught in the Academy. To him in his old age came a certain good-looking youngster from Stagira in Macedonia, Aristotle, who was the son of the Macedonian king’s physician, and a man with a very different type of mind from that of the great Athenian. He was naturally sceptical of the imaginative will, and with a great respect for and comprehension of established fact. Later on, after Plato was dead, he set up a school at the Lyceum in Athens and taught, criticizing Plato and Socrates with a certain hardness. When he taught, the shadow of Alexander the Great lay across the freedom of Greece, and he favoured slavery and constitutional kings. He had previously been the tutor of Alexander for several years at the court of Philip of Macedon.[189] Intelligent men were losing heart in those days, their faith in the power of men to make their own conditions of life was fading. There were no more Utopias. The rush of events was manifestly too powerful for such organized effort as was then practicable between men of fine intelligence. It was possible to think of recasting human society when human society was a little city of a few thousand citizens, but what was happening about them was something cataclysmal; it was the political recasting of the whole known world, of the affairs of what even then must have amounted to something between fifty and a hundred million people. It was recasting upon a scale no human mind was yet equipped to grasp. It drove thought back upon the idea of a vast and implacable Fate. It made men snatch at whatever looked stable and unifying. Monarchy, for instance, for all its manifest vices, was a conceivable government for millions; it had, to a certain extent, worked; it imposed a ruling will where it would seem that a collective will was impossible. This change of the general intellectual mood harmonized with Aristotle’s natural respect for existing fact. If, on the one hand, it made him approve of monarchy and slavery and the subjection of women as reasonable institutions, on the other hand it made him eager to understand fact and to get some orderly knowledge of these realities of nature and human nature that were now so manifestly triumphant over the creative dreams of the preceding generation. He is terribly sane and luminous, and terribly wanting in self-sacrificial enthusiasm. He questions Plato when Plato would exile poets from his Utopia, for poetry is a power; he directs his energy along a line diametrically opposed to Socrates’ depreciation of Anaxagoras. He anticipates Bacon and the modern scientific movement in his realization of the importance of ordered knowledge. He set himself to the task of gathering together and setting down knowledge. He was the first natural historian. Other men before him had speculated about the nature of things, but he, with every young man he could win over to the task, set himself to classify and compare things. Plato says in effect: “Let us take hold of life and remodel it;” this soberer successor: “Let us first know more of life and meanwhile serve the king.” It was not so much a contradiction as an immense qualification of the master.
The peculiar relation of Aristotle to Alexander the Great enabled him to procure means for his work such as were not available again for scientific inquiry for long ages. He could command hundreds of talents (a talent = about £240) for his expenses. At one time he had at his disposal a thousand men scattered throughout Asia and Greece, collecting matter for his natural history.[190][191] They were, of course, very untrained observers, collectors of stories rather than observers; but nothing of the kind had ever been attempted, had even been thought of, so far as we know, before his time. Political as well as natural science began. The students of the Lyceum under his direction made an analysis of 158 political constitutions....
This was the first gleam of organized science in the world. The early death of Alexander and the breaking up of his empire almost before it had begun, put an end to endowments on this scale for 2000 years. Only in Egypt at the Alexandria Museum did any scientific research continue, and that only for a few generations. Fifty years after Aristotle’s death the Lyceum had already dwindled to insignificance.
§ 7
The general drift of thought in the concluding years of the fourth century B.C. was not with Aristotle, nor towards the laborious and necessary accumulation of ordered knowledge. It is possible that without his endowments from the king he would have made but a small figure in intellectual history. Through them he was able to give his splendid intelligence substance and effect. The ordinary man prefers easy ways so long as they may be followed, and is almost wilfully heedless whether they end at last in a cul-de-sac. Finding the stream of events too powerful to control at once, the generality of philosophical teachers drifted in those days from the scheming of model cities and the planning of new ways of living into the elaboration of beautiful and consoling systems of evasion.
Perhaps that is putting things coarsely and unjustly. But let Professor Gilbert Murray speak upon this matter.[192]
“The Cynics cared only for virtue and the relation of the soul to God; the world and its learning and its honours were as dross to them. The Stoics and Epicureans, so far apart at first sight, were very similar in their ultimate aim. What they really cared about was ethics—the practical question how a man should order his life. Both, indeed, gave themselves to some science—the Epicureans to physics, the Stoics to logic and rhetoric—but only as a means to an end. The Stoic tried to win men’s hearts and convictions by sheer subtlety of abstract argument and dazzling sublimity of thought and expression. The Epicurean was determined to make Humanity go its way without cringing to capricious gods and without sacrificing Free-Will. He condensed his gospel into four maxims: ‘God is not to be feared; Death cannot be felt; the Good can be won; all that we dread can be borne and conquered.’”
