During their life these social myths contain a nation's finest energy. It is just because they are "not descriptions of things, but expressions of will" that their influence is so great. Ignore what a man desires and you ignore the very source of his power; run against the grain of a nation's genius and see where you get with your laws. Robert Burns was right when he preferred poetry to charters. The recognition of this truth by Sorel is one of the most impressive events in the revolutionary movement. Standing as a spokesman of an actual social revolt, he has not lost his vision because he understands its function. If Machiavelli is a symbol of the political theorist making reason an instrument of purpose, we may take Sorel as a self-conscious representative of the impulses which generate purpose.

It must not be supposed that respect for the myth is a discovery of Sorel's. He is but one of a number of contemporary thinkers who have reacted against a very stupid prejudice of nineteenth century science to the effect that the mental habits of human beings were not "facts." Unless ideas mirrored external nature they were regarded as beneath the notice of the scientific mind. But in more recent years we have come to realize that, in a world so full of ignorance and mistake, error itself is worthy of study. Our untrue ideas are significant because they influence our lives enormously. They are "facts" to be investigated. One might point to the great illumination that has resulted from Freud's analysis of the abracadabra of our dreams. No one can any longer dismiss the fantasy because it is logically inconsistent, superficially absurd, or objectively untrue. William James might also be cited for his defense of those beliefs that are beyond the realm of proof. His essay, "The Will to Believe," is a declaration of independence, which says in effect that scientific demonstration is not the only test of ideas. He stated the case for those beliefs which influence life so deeply, though they fail to describe it. James himself was very disconcerting to many scientists because he insisted on expressing his aspirations about the universe in what his colleague Santayana calls a "romantic cosmology": "I am far from wishing to suggest that such a view seems to me more probable than conventional idealism or the Christian Orthodoxy. All three are in the region of dramatic system-making and myth, to which probabilities are irrelevant."

It is impossible to leave this point without quoting Nietzsche, who had this insight and stated it most provocatively. In "Beyond Good and Evil" Nietzsche says flatly that "the falseness of an opinion is not for us any objection to it: it is here, perhaps, that our new language sounds most strangely. The question is, how far an opinion is life-furthering, life-preserving, species-preserving, perhaps species-rearing...." Then he comments on the philosophers. "They all pose as though their real opinions had been discovered and attained through the self-evolving of a cold, pure, divinely indifferent dialectic...; whereas, in fact, a prejudiced proposition, idea, or 'suggestion,' which is generally their heart's desire abstracted and refined, is defended by them with arguments sought out after the event. They are all advocates who do not wish to be regarded as such, generally astute defenders, also, of their prejudices, which they dub 'truths'--and very far from having the conscience which bravely admits this to itself; very far from having the good taste or the courage which goes so far as to let this be understood, perhaps to warn friend or foe, or in cheerful confidence and self-ridicule.... It has gradually become clear to me what every great philosophy up till now has consisted of--namely, the confession of its originator, and a species of involuntary and unconscious autobiography, and, moreover, that the moral (or immoral) purpose in every philosophy has constituted the true vital germ out of which the entire plant has always grown.... Whoever considers the fundamental impulses of man with a view to determining how far they may have acted as inspiring genii (or as demons and cobolds) will find that they have all practiced philosophy at one time or another, and that each one of them would have been only too glad to look upon itself as the ultimate end of existence and the legitimate lord over all the other impulses. For every impulse is imperious, and, as such, attempts to philosophize."

What Nietzsche has done here is, in his swashbuckling fashion, to cut under the abstract and final pretensions of creeds. Difficulties arise when we try to apply this wisdom in the present. That dogmas were instruments of human purposes is not so incredible; that they still are instruments is not so clear to everyone; and that they will be, that they should be--this seems a monstrous attack on the citadel of truth. It is possible to believe that other men's theories were temporary and merely useful; we like to believe that ours will have a greater authority.

It seems like topsy-turvyland to make reason serve the irrational. Yet that is just what it has always done, and ought always to do. Many of us are ready to grant that in the past men's motives were deeper than their intellects: we forgive them with a kind of self-righteousness which says that they knew not what they did. But to follow the great tradition of human wisdom deliberately, with our eyes open in the manner of Sorel, that seems a crazy procedure. A notion of intellectual honor fights against it: we think we must aim at final truth, and not allow autobiography to creep into speculation.

Now the trouble with such an idol is that autobiography creeps in anyway. The more we censor it, the more likely it is to appear disguised, to fool us subtly and perhaps dangerously. The men like Nietzsche and James who show the wilful origin of creeds are in reality the best watchers of the citadel of truth. For there is nothing disastrous in the temporary nature of our ideas. They are always that. But there may very easily be a train of evil in the self-deception which regards them as final. I think God will forgive us our skepticism sooner than our Inquisitions.

From the political point of view, another observation is necessary. The creed of a Rousseau, for example, is active in politics, not for what it says, but for what people think it says. I have urged that Marx found scientific reasons for what he wanted to do. It is important to add that the people who adopted his reasons for what they wanted to do were not any too respectful of Marx's reasons. Thus the so-called materialistic philosophy of Karl Marx is not by any means identical with the theories one hears among Marxian socialists. There is a big distortion in the transmitting of ideas. A common purpose, far more than common ideas, binds Marx to his followers. And when a man comes to write about his philosophy he is confronted with a choice: shall the creed described be that of Marx or of the Marxians?

For the study of politics I should say unhesitatingly that it is more important to know what socialist leaders, stump speakers, pamphleteers, think Marx meant, than to know what he said. For then you are dealing with living ideas: to search his text has its uses, but compared with the actual tradition of Marx it is the work of pedantry. I say this here for two reasons--because I hope to avoid the critical attack of the genuine Marxian specialist, and because the observation is, I believe, relevant to our subject.

Relevant it is in that it suggests the importance of style, of propaganda, the popularization of ideas. The host of men who stand between a great thinker and the average man are not automatic transmitters. They work on the ideas; perhaps that is why a genius usually hates his disciples. It is interesting to notice the explanation given by Frau Förster-Nietzsche for her brother's quarrel with Wagner. She dates it from the time when Nietzsche, under the guise of Wagnerian propaganda, began to expound himself. The critics and interpreters are themselves creative. It is really unfair to speak of the Marxian philosophy as a political force. It is juster to speak of the Marxian tradition.

So when I write of Marx's influence I have in mind what men and women in socialist meetings, in daily life here in America, hold as a faith and attribute to Marx. There is no pretension whatever to any critical study of "Das Kapital" itself. I am thinking rather of stuffy halls in which an earnest voice is expounding "the evolution of capitalism," of little groups, curious and bewildered, listening in the streets of New York to the story of the battle between the "master class" and the "working class," of little red pamphlets, of newspapers, and cartoons--awkward, badly printed and not very genial, a great stream of spellbinding and controversy through which the aspirations of millions are becoming articulate:
