This is a great emancipation. Instead of clinging to the naïve belief that Plato was legislating for all mankind, you can discuss his plans as a temporary superstructure made for an historical purpose. You are free then to appreciate the more enduring portions of his work, to understand Santayana when he says of the Platonists, "their theories are so extravagant, yet their wisdom seems so great. Platonism is a very refined and beautiful expression of our natural instincts, it embodies conscience and utters our inmost hopes." This insight into the values of human life, partial though it be, is what constitutes the abiding monument of Plato's genius. His constructions, his formal creeds, his law-making and social arrangements are local and temporary--for us they can have only an antiquarian interest.
In some such way as this the sophomoric riddle is answered: no thinker can lay down a course of action for all mankind--programs if they are useful at all are useful for some particular historical period. But if the thinker sees at all deeply into the life of his own time, his theoretical system will rest upon observation of human nature. That remains as a residue of wisdom long after his reasoning and his concrete program have passed into limbo. For human nature in all its profounder aspects changes very little in the few generations since our Western wisdom has come to be recorded. These aperçus left over from the great speculations are the golden threads which successive thinkers weave into the pattern of their thought. Wisdom remains; theory passes.
If that is true of Plato with his ample vision how much truer is it of the theories of the littler men--politicians, courtiers and propagandists who make up the academy of politics. Machiavelli will, of course, be remembered at once as a man, whose speculations were fitted to an historical crisis. His advice to the Prince was real advice, not a sermon. A boss was telling a governor how to extend his power. The wealth of Machiavelli's learning and the splendid penetration of his mind are used to interpret experience for a particular purpose. I have always thought that Machiavelli derives his bad name from a too transparent honesty. Less direct minds would have found high-sounding ethical sanctions in which to conceal the real intent. That was the nauseating method of nineteenth century economists when they tried to identify the brutal practices of capitalism with the beneficence of nature and the Will of God. Not so Machiavelli. He could write without a blush that "a prince, especially a new one, cannot observe all those things for which men are esteemed, being often forced, in order to maintain the state, to act contrary to fidelity, friendship, humanity, and religion." The apologists of business also justified a rupture with human decencies. They too fitted their theory to particular purposes, but they had not the courage to avow it even to themselves.
The rare value of Machiavelli is just this lack of self-deception. You may think his morals devilish, but you cannot accuse him of quoting scripture. I certainly do not admire the end he serves: the extension of an autocrat's power is a frivolous perversion of government. His ideal happens, however, to be the aim of most foreign offices, politicians and "princes of finance." Machiavelli's morals are not one bit worse than the practices of the men who rule the world to-day. An American Senate tore up the Hay-Pauncefote treaty, and with the approval of the President acted "contrary to fidelity" and friendship too; Austria violated the Treaty of Berlin by annexing Bosnia and Herzegovina. Machiavelli's ethics are commonplace enough. His head is clearer than the average. He let the cat out of the bag and showed in the boldest terms how theory becomes an instrument of practice. You may take him as a symbol of the political theorist. You may say that all the thinkers of influence have been writing advice to the Prince. Machiavelli recognized Lorenzo the Magnificent; Marx, the proletariat of Europe.
At first this sounds like standing the world on its head, denying reason and morality, and exalting practice over righteousness. That is neither here nor there. I am simply trying to point out an illuminating fact whose essential truth can hardly be disputed. The important social philosophies are consciously or otherwise the servants of men's purposes. Good or bad, that it seems to me is the way we work. We find reasons for what we want to do. The big men from Machiavelli through Rousseau to Karl Marx brought history, logic, science and philosophy to prop up and strengthen their deepest desires. The followers, the epigones, may accept the reasons of Rousseau and Marx and deduce rules of action from them. But the original genius sees the dynamic purpose first, finds reasons afterward. This amounts to saying that man when he is most creative is not a rational, but a wilful animal.
The political thinker who to-day exercises the greatest influence on the Western World is, I suppose, Karl Marx. The socialist movement calls him its prophet, and, while many socialists say he is superseded, no one disputes his historical importance. Now Marx embalmed his thinking in the language of the Hegelian school. He founded it on a general philosophy of society which is known as the materialistic conception of history. Moreover, Marx put forth the claim that he had made socialism "scientific"--had shown that it was woven into the texture of natural phenomena. The Marxian paraphernalia crowds three heavy volumes, so elaborate and difficult that socialists rarely read them. I have known one socialist who lived leisurely on his country estate and claimed to have "looked" at every page of Marx. Most socialists, including the leaders, study selected passages and let it go at that. This is a wise economy based on a good instinct. For all the parade of learning and dialectic is an after-thought--an accident from the fact that the prophetic genius of Marx appeared in Germany under the incubus of Hegel. Marx saw what he wanted to do long before he wrote three volumes to justify it. Did not the Communist Manifesto appear many years before "Das Kapital"?
Nothing is more instructive than a socialist "experience" meeting at which everyone tries to tell how he came to be converted. These gatherings are notoriously untruthful--in fact, there is a genial pleasure in not telling the truth about one's salad days in the socialist movement. The prevalent lie is to explain how the new convert, standing upon a mountain of facts, began to trace out the highways that led from hell to heaven. Everybody knows that no such process was actually lived through, and almost without exception the real story can be discerned: a man was dissatisfied, he wanted a new condition of life, he embraced a theory that would justify his hopes and his discontent. For once you touch the biographies of human beings, the notion that political beliefs are logically determined collapses like a pricked balloon. In the language of philosophers, socialism as a living force is a product of the will--a will to beauty, order, neighborliness, not infrequently a will to health. Men desire first, then they reason; fascinated by the future, they invent a "scientific socialism" to get there.
Many people don't like to admit this. Or if they admit it, they do so with a sigh. Their minds construct a utopia--one in which all judgments are based on logical inference from syllogisms built on the law of mathematical probabilities. If you quote David Hume at them, and say that reason itself is an irrational impulse they think you are indulging in a silly paradox. I shall not pursue this point very far, but I believe it could be shown without too much difficulty that the rationalists are fascinated by a certain kind of thinking--logical and orderly thinking--and that it is their will to impose that method upon other men.
For fear that somebody may regard this as a play on words drawn from some ultra-modern "anti-intellectualist" source, let me quote Santayana. This is what the author of that masterly series "The Life of Reason" wrote in one of his earlier books: "The ideal of rationality is itself as arbitrary, as much dependent on the needs of a finite organization, as any other ideal. Only as ultimately securing tranquillity of mind, which the philosopher instinctively pursues, has it for him any necessity. In spite of the verbal propriety of saying that reason demands rationality, what really demands rationality, what makes it a good and indispensable thing and gives it all its authority, is not its own nature, but our need of it both in safe and economical action and in the pleasures of comprehension." Because rationality itself is a wilful exercise one hears Hymns to Reason and sees it personified as an extremely dignified goddess. For all the light and shadow of sentiment and passion play even about the syllogism.
The attempts of theorists to explain man's successes as rational acts and his failures as lapses of reason have always ended in a dismal and misty unreality. No genuine politician ever treats his constituents as reasoning animals. This is as true of the high politics of Isaiah as it is of the ward boss. Only the pathetic amateur deludes himself into thinking that, if he presents the major and minor premise, the voter will automatically draw the conclusion on election day. The successful politician--good or bad--deals with the dynamics--with the will, the hopes, the needs and the visions of men.
