Progress and History. Various
the less, and this is important, this world does not cease to be significant for him. He does not turn aside—as some souls, intoxicated with the Divine, have done—from this world altogether.
Because he holds that man can only advance by struggling to make this world better. Man's ordinary life may be like the life in a cave, as he says in his famous myth, but the true philosopher who has once risen out of the cave must go back into it again and teach the prisoners there what the universe really is (Republic, Book vi, fin.; vii, init.). The very passage that I quoted about man's real nature comes at the end of the Republic. Now the Republic is a Utopia, and no one writes a Utopia unless he believes that the effort to reach it is of prime importance to man and helps him to advance.
Only, for Plato, the advance is not marked in the successive stages of history, as the modern faith in progress asserts. The life on earth, for Plato, is like a school through which men pass and in which they may learn and grow, but the school itself does not go on growing. It is not that he does not envisage change in history, but what he seems to hope for at the best is nothing more hopeful than recurring cycles of better and worse. He tells a fable, in his dialogue 'The Statesman', of how at one time the world is set spinning in the right direction by God and then all goes well, and again how God ceases to control it, and then it gradually forgets the divine teaching and slips from good to bad and from bad to worse, until at last God takes pity on it once more to save it from utter destruction (Polit. 269 ff.). No doubt in this idea of cycles Plato is influenced by the popular thought of his time: this feeling that there had been a lost Golden Age in the past was deeply rooted in Greek mythology. We get it long before Plato, in Hesiod, and there are similar touches in Homer, and once men believe that they have sunk from glory, there is always the dread that if ever they recover it they will lose it again. And with Plato this dread is reinforced by his sense of something incurable in the world, the thwarting influence of spatial and temporal matter (Theaet. 176 a).
It is strange that, though he is always thinking of the individual soul as learning through experience in its passage from one life to another, Plato does not seem to have the idea of mankind learning by the lessons of history, of knowledge being handed down from one age to another, and growing in the process. That is one of the most inspiring ideas in modern thought: a German writer has spoken of history as the long Odyssey of the human spirit, the common mind of Man coming at last through its wanderings to find out what it really wants, and where its true home lies.
And here, significantly enough, we find we are brought back in our modern way to something very like Plato's own conception of an eternal unchanging Reality. There are endless problems in the whole conception of the Eternal that I am quite unable even to attempt; but this much at least seems clear to me, that the whole idea of mankind learning by the experience of History, implies something of permanent value running through that experience. The very thought of continued progress implies that man can look back at the successive stages of the Past and say of each: In that lay values which I, to-day and always, can recognize as good, although I believe we have more good now. Seeley speaks in a noble passage of how religion might conceive a progressive revelation which was, in a sense, the same through all its stages, and yet was a growing thing:—'each new revelation asserts its own superiority to those which went before,' but the superiority is 'not of one thing to another thing—but of the developed thing to the undeveloped'. 'It is thus', he writes, 'that the ages should behave to one another.' This is the true 'understanding and concert with time'.[10] And though Plato does not live in the thought of historic progress, yet such a conception of progress which recognizes at different stages different expressions, more or less adequate, of one eternal value, such a way of thinking is entirely Platonic. When we look back at history in this mood we think not only of grasping the right principles for the Future, but of rejoicing in the definite achievements of the Past, and we feel this most poignantly, I think, of the achievements won by the spirit of Beauty. Great works of Art we are accustomed actually to call immortal, and we mean by this not merely that we think they will always be famous, but that there is something in them that makes it impossible for them ever to be superseded. In themselves they are inexhaustible: if they cease to interest us, it is our fault and not theirs. We may want more, we do want more, where they came from, but we never want to lose them, any more than we could bear to lose our old friends, though we may desire to make new ones. Of all the divine Ideas, said Plato, Beauty is the one that shows itself most plainly in the world of sense and speaks to us most plainly of the eternal realities.
This, however, is perhaps trenching on the subject of Progress in Art, and I should like to return to the general Greek conception of the tendency in all nature towards the Good, the perfect realization of perfect types.
Plato does not expressly insist that this tendency is of the nature of effort, though I think that is involved in his view. But Aristotle does. Following Plato in essentials, he makes bold to say outright that every natural thing in its own way longs for the divine and desires to share in the divine life, so far as it can.[11] Every such thing in this world of space and time has to cope with difficulties and is imperfect, but everything struggles towards the good. That good is in the life of God, a thinking life, an activity of thought, existing in some sense beyond this imperfect world; and this life is so supremely desirable that it makes everything else struggle to reach it. It moves the whole world, Aristotle says, in a famous passage, because it is loved. It is the world's desire.[12]
Now this idea of effort—or of something analogous to effort—constituting the inner nature of every natural thing reappears, with pregnant consequences, in modern thought, though seldom with these vast theological consequences. The idea of an upward effort through nature lies at the base of our most hopeful theories of evolution, and forms the true support of our modern faith in progress. Broadly speaking, our evolutionists are now divided into two schools: the adherents of the one believe that variations are purely accidental, and may occur in any direction whatsoever, the useful ones being preserved only because they happen to be useful for the life of the species, while the adherents of the other—the school that I would call the school of hope—believe that accident, even with natural selection to aid it, is utterly inadequate to account for the ordered beauty and harmony that we do see in natural things. They admit, as Plato and Aristotle admit, imperfection and difficulty in the world, but they insist on a movement towards value: in short, they conceive an order emerging that is brought about, to quote a modern writer, both in nature and in society, by 'a principle of movement and progress conflicting with a principle of inertia.'[13]
Aristotle, in words that are strikingly modern, raises the very question at issue here.[14] He asks whether we can suppose that nature does not aim at the good at all, but that variations arise by chance and are preserved just because they are useful, and he scouts the idea that chance could do more, as Zeller says, than 'bring about isolated and abnormal results'. He chooses instead the conception of purpose and effort, and this in spite of the difficulties in conceiving a purpose and an effort that are not definitely conscious. The sort of thing that is in Aristotle's mind when he speaks of nature aiming at the good, comes out in a passage by Edward Carpenter in his little book The Art of Creation. Carpenter plunges boldly and compares the principle that makes a tree grow and propagate its kind with the impulse that makes a man express himself. Man, he says,
has a Will and Purpose, a Character, which, do what you will, tends to push outwards towards expression. You put George Fox in prison, you flog and persecute him, but the moment he has a chance he goes and preaches just the same as before. … But take a Tree and you notice exactly the same thing. A dominant Idea informs the life of the Tree; persisting, it forms the tree. You may snip the leaves as much as you like to a certain pattern, but they will only grow in their own shape. Finally, you may cut the tree down root and branch and burn it, but, if there is left a single seed, within that seed … lurks the formative ideal, which under proper conditions will again spring into life and expression.
