And so, fourthly, the contradictions of experience make experience supremely practical. They make it practical just because they make realistic, or substantial, an experience which without them would be abstract and only relative and "phenomenal." Possibly this is the hardest thing of all to apprehend, or at least to express satisfactorily. Yet the fact, to which I keep returning, that only the both-sided in everyday matters or in science or in any form of positive experience can accord with reality and its wholeness, is assuredly quite to the point. In practical life there always are, and emphatically there always must be, two sides, to every thing, to every question. In practical life, too, or at any rate in all effective activity, there always is, and emphatically there always must be, something very like to leadership; but any truly practical leadership, any leadership that is all along the lines of life, be it of things, ideas, persons, or social classes or parties, can never be confined to a single individual representative, but must be instead a leadership of many. No thoroughly practical leadership, I say, can ever be on one side or the other, but instead of being one-sided it must be both-sided, or rather, infinitely many-sided; it must be between or among all the different and opposed individuals; it must lie, perhaps in a sense sleep, in rivalry and competition. There can be no visible leader, whose leadership is wholly practical, whether of things or realities—for the metaphysician—or of ideas or categories—for the logician—or of persons or classes—for the statesman or the moralist or the theologian. Metaphysical reality, the truly practical and realistic knowledge, the political supremacy which is complete and inclusive, or the wholly moral life or the divine life must forever be secured, not through a single manifestation presiding over the others, but through the divided labour of them all. Yes, real leadership, like real unity in general, is a divided labour; it is a labour that effects successful co-operation through its very differences and conflicts: for reality, a labour perhaps of different "elements" or "entities"; for knowledge, of different ideas and standpoints; for morals, of different standards; for politics, of different parties and platforms; for divinity, of different Gods; and for life at large, a labour of infinite differences, which means also a labour of opposites, that at once develop and correct each other to the glory of that which is real and practical.

It would be peculiarly interesting to examine further this principle of a practical, truly realistic experience ensured to human life through the inner conflicts of experience. The history of morals and ethics, for example, notably of the perennial conflict between hedonism and idealism, could not but cast a good deal of light upon it; and the history of political struggles, or the history of the great controversies in science—such as that between vitalism and anti-vitalism or that between atomism and energism; or in philosophy, between dualism and monism; or in theology, between naturalism and supernaturalism, would also be most illuminating; while, also perhaps appealing only to the few, in the logic of the negative, as it has developed from the earliest times, or in psychological theory—for example, in the dispute of the advocates of the innervation theory and the afferent theory, or in Hering's theory of vision, or, again, in the life and movement of any one of the time-worn paradoxes of popular or scientific or philosophical ideas, one might expect to find suggestive illustration. In philosophy, Anaximander, Heraclitus, Zeno, Socrates, Spinoza, Kant, and Hegel have all found negation, or contradiction, necessary to any adequate account of reality. Explorations, however, in their teachings or along any of the paths that were suggested, would lead us too far astray.

Fifthly, then, not only do the contradictions make experience realistic and so practical, but also they make it essentially social. A life or an experience that is contradictory has (1) movement, (2) unity or integrity, (3) reality and poise, and (4) practicality; and then it has besides, as if the medium through which these four things are sustained, (5) social character, society being only the visible expression, the outer realization, of the both-sidedness, of the infinitely differential unity or the divided labour, which an active, yet thoroughly self-controlled, truly realistic, practical experience requires. In a former chapter, it will be readily recalled, an impulse to social life was found to be intimately connected with the attitude of doubt, and here clearly we are confronted with only another view of the same fact, since contradiction has become our most cogent reason for doubt and is now seen to require the social relations. An individual whose experience is ever divided against itself is, ipso facto, a social character, his social environment, whether in its narrowest or broadest manifestation, adding nothing to his nature or to the struggles of that nature, but only making the division against himself constantly and manifestly real. The social environment, as it were, just proves the man, his struggle and all, to himself. Some have agreed that the individual consciousness contained nothing on which to ground a positive case for society, for direct positive social interest; but so long as man's experience is necessarily paradoxical or contradictory, so long as man is divided against himself, or as the labour of life and reality is a divided labour, the case for society and for personal interest in society is clear and conclusive. A basis for society lies in the very nature of experience. Society is not something added to individuality from without.

Let us here beware of easy sentiment. Let not our thinking conjure false sweetness and light. Experience is truly and essentially social; the individual was not meant to dwell alone; but herein is no immediate cure-all, no promise of an unperturbed brotherly love, of a life for one and all of simple peace and blissful quietude. On such a plan society would hardly suit the individual with whom, and with whose natural experience, we have become acquainted. To speak with the extravagance of a counter-sentimentalism, the individual of our present acquaintance is forever spoiling for a fight. In the life of the society to which he belongs; in the life where he watches for his incoming ship, there must always be hate and evil in all their forms, lawlessness and destruction, illusion and error; but—and just here sentiment, the sentiment of a really searching optimism, called once before a sacrificial and heroic optimism, may find some assurance—never an unmixed hate, never a wholly idle destruction, never an unmeaning error. Can anything, indeed, that has another thing against it—that has, in short, an opposite—ever be itself unmixed? The good or the evil in society, being always opposed, is always also shared. So few people recognize, or appreciate, what a great mixer opposition is. Death is the passing only of inadequate or unworthy life. Hate witnesses only a false love; sin, a pharisaical righteousness. Destruction marks an imperfect construction. And in all its forms, evil is not so much something in and by itself as an exposure and reproach of what is supposed to be unmixedly good. Public crime, for example, is not so local as it appears; it is only a generally, widely private vice made locally manifest, and the respectable and law-abiding, who adjudge it evil, are bound to feel as if adjudging and condemning themselves. In a word, the individual's natural society is never without evil, but in all its forms the evil has somewhat of good in it; and although social life, not less than individual life, must be one of conflict and discord, nevertheless, because the various factors or factions, however opposed, can never be unmixed, because the members of society must all be good and bad, right and wrong—I almost said living and dead together—instead of being hopeless for having evil in it, the life of society is so much the more worth living. Shallow sentimentalism may not so esteem it, but we need give little thought to shallow sentimentalism.

So our use of the word "society" is not sentimental. Society means conflict. It is just the natural sphere of life and reality as for ever a divided labour, as for ever divided and laborious—divided even between the powers for supposed good and for adjudged evil, and through the conflicts, in which the division is expressed, what is true and good and vital is being forever kept real. Or, to repeat, society is the natural medium through which movement, unity or integrity, poise and reality, and practicality are secured and realized in human experience; it is that which makes the individual's division against himself manifestly real and positively and progressively effective for a life, yes, for his life, at once of vitality and perfect wholeness.

But now that the five things are said, now that the contradictions of experience have been seen to serve experience by giving it movement, unity, poise, practical reality and social character, somebody is sure to remark facetiously that on the evidence contradiction is something we should all cultivate assiduously, and that henceforth to face both ways, the butt of so much opprobrium, should be one of man's greatest ideals; in brief, that the inconsistent creatures in politics, morals, and theology are the coming examples for mankind. Verily the devil has been given his promised "character." But, alas! in the spirit of such startling humour one would have to conclude also that because crime has beyond all question been a means of social development, being all-important to the awakening of the social consciousness and conscience, all men should at once take thought and find it their duty to turn criminals; or, again, that because death has a fundamental part in the order of nature and is, moreover, of greatest spiritual worth and significance, we should all morbidly seek it, being successfully righteous only by being suicides. True, we do need to recognize the positive function of crime in the progress of civilization, or in the history of law, and also to be aware of crime as a possibility in our own lives, and we need to be ready to die and to feel besides that dying we are far from losing all that is worth having, but to court crime or to seek death would certainly be to deprive either of the very worth which has made it significant. And in much the same way we may very profitably recognize contradiction or controversy, whether personal or social, as a necessary condition of all valid experience, but not on that account are we to cultivate what is contradictory, to be always blindly spoiling for a contradiction. Like crime or death, if directly courted, contradiction would lose its peculiar effectiveness. The both-sidedness or the all-sidedness, which at once develops and conserves human life, is only that which is maintained with a tenacious, even with a would-be consistent loyalty to each and every side.

So, although grossly misused if directly courted, this defect of experience has its place, even its ideal value, in experience, and what on the surface seemed an almost if not quite hopeless reason for doubt, has truly become all but transfigured, seeming now a source of real assurance. With Heraclitus of old, only perhaps seeing even more than he saw, we can glory in a world of strife. Doubting all things, we can yet believe that all things work together for what is real, for what is good.

But let me now put the result, so far secured, of our confession of doubt in a new way. For a life in which every thing has an opposite, every idea a counter-idea, truth very plainly, as has indeed been frequently said, cannot be a specific consciousness nor reality a fixed thing. Truth is not a creed, but a spirit. Reality is not a thing, but a life. And for being a spirit truth is only the more realistic? For being a life, reality is only the more substantial. Perfection, too, even the Perfect One, with whom we associate the true and the real, is no particular separate being in a certain established exclusive status, at once infinitely and passively excellent, but a power ever dwelling in the strife that makes for movement and poise. For being such a power, too, he is only more surely perfect, only more certainly infinite and excellent.

Such terms as spirit, life, and power are confessedly somewhat dangerous terms to use. Especially the first is liable to misunderstanding. Yet, whatever common usage may be, when I say that truth is not a creed but a spirit, that reality is not a thing but a power, the reference is directly to that agent or principle of validity which has been found to hold our experience, naturally so faulty, to contact and intimacy with the real world. A spirit of truth, a principle of validity there is, to which the very faults of experience give witness, and in view of this we who doubt, who doubt the particular things, the creeds and the objects generally, the definite forms and ideas, the habits and standpoints of our everyday life or our scientific theory, may yet believe; we may believe in the real spirit, or power, which makes all things parties to the divided labour of a real life.[2]
