Bradley and his friends achieved a notable victory in the academic field: philosophic authority and influence pa.s.sed largely into their hands in all English-speaking universities. But it was not exactly from these seats of learning that naturalism and utilitarianism needed to be dislodged; like the corresponding radicalisms of our day, these doctrines prevailed rather in certain political and intellectual circles outside, consciously revolutionary and often half-educated; and I am afraid that the braggart Goliaths of today need chastening at least as much as those of fifty years ago. In a country officially Christian, and especially in Oxford, it is natural and fitting that academic authority should belong to orthodox tradition--theological, Platonic, and Aristotelian. Bradley, save for a few learned quotations, strangely ignored this orthodoxy entrenched behind his back. In contrast with it he was himself a heretic, with first principles devastating every settled belief: and it was really this venerable silent partner at home that his victory superseded, at least in appearance and for a season. David did not slay Goliath, but he dethroned Saul. Saul was indeed already under a cloud, and all in David"s heart was not unkindness in that direction. Bradley might almost be called an unbelieving Newman; time, especially, seems to have brought his suffering and refined spirit into greater sympathy with ancient sanct.i.ties.
Originally, for instance, venting the hearty Protestant sentiment that only the Christianity of laymen is sound, he had written: "I am happy to say that "religieux" has no English equivalent". But a later note says: "This is not true except of Modern English only. And, in any case, it won"t do, and was wrong and due to ignorance. However secluded the religious life, it may be practical indirectly _if_ through the unity of the spiritual body it can be taken as vicarious". The "_if_" here saves the principle that all values must be social, and that the social organism is the sole moral reality: yet how near this bubble comes to being p.r.i.c.ked! We seem clearly to feel that the question is not whether spiritual life subserves animal society, but whether animal society ever is stirred and hallowed into spiritual life.
All this, however, in that age of progress, was regarded as obsolete: there was no longer to be any spirit except the spirit of the times. True, the ritualists might be striving to revive the latent energies of religious devotion, with some dubious help from aestheticism: but against the rising tide of mechanical progress and romantic anarchy, and against the mania for rewriting history, traditional philosophy then seemed helpless and afraid to defend itself: it is only now beginning to recover its intellectual courage. For the moment, speculative radicals saw light in a different quarter. German idealism was nothing if not self-confident; it was relatively new; it was encyclopaedic in its display of knowledge, which it could manipulate dialectically with dazzling, if not stable, results; it was Protestant in temper and autonomous in principle; and altogether it seemed a sovereign and providential means of suddenly turning the tables on the threatened naturalism. By developing romantic intuition from within and packing all knowledge into one picture, the universe might be shown to be, like intuition itself, thoroughly spiritual, personal, and subjective.
The fundamental axiom of the new logic was that the only possible reality was consciousness.
"People find", writes Bradley, "a subject and an object correlated in consciousness.... To go out of that unity is for us literally to go out of our minds.... When mind is made only a part of the whole, there is a question which _must_ be answered.... If about any matter we know nothing whatsoever, can we say anything about it?
Can we even say that it is? And if it is not in consciousness, how can we know it?... And conversely, if we know it, it cannot be not mind."
Bradley challenged his contemporaries to refute this argument; and not being able to do so, many of them felt constrained to accept it, perhaps not without grave misgivings. For was it not always a rooted conviction of the British mind that knowledge brings material power, and that any figments of consciousness (in religion, for instance) not bringing material power are dangerous bewitchments, and not properly knowledge?
Yet it is no less characteristic of the British mind to yield occasionally, up to a certain point, to some such enthusiastic fancy, provided that its incompatibility with honest action may be denied or ignored. So in this case British idealists, in the act of defining knowledge idealistically, as the presence to consciousness of its own phenomena, never really ceased to a.s.sume transcendent knowledge of a self-existing world, social and psychological, if not material: and they continued scrupulously to readjust their ideas to those dark facts, often more faithfully than the avowed positivists or scientific psychologists.
What could ethics properly be to a philosopher who on principle might not trespa.s.s beyond the limits of consciousness? Only ethical sentiment.
Bradley was satisfied to appeal to the moral consciousness of his day, without seeking to transform it. The most intentionally eloquent pa.s.sage in his book describes war-fever unifying and carrying away a whole people: that was the summit of moral consciousness and of mystic virtue. His aim, even in ethics, was avowedly to describe that which exists, to describe moral experience, without proposing a different form for it. A man must be a man of his own time, or nothing; to set up to be better than the world was the beginning of immorality; and virtue lay in accepting one"s station and its duties. The moralist should fill his mind with a concrete picture of the task and standards of his age and nation, and should graft his own ideals upon that tree; this need not prevent moral consciousness from including a decided esteem for non-political excellences like health, beauty, or intelligence, which are not ordinarily called virtues by modern moralists. Yet they were undeniably good; better, perhaps, than any painful and laborious dutifulness; so that the strictly moral consciousness might run over, and presently lose itself in "something higher". Indeed, even health, beauty, and intelligence, which seemed at first so clearly good, might lose their sharpness on a wider view. In the panorama that would ultimately fill the mind these so-called goods and virtues could not be conceived without their complementary vices and evils. Thus all moral consciousness, and even all vital preference might ultimately be superseded: they might appear to have belonged to a partial and rather low stage in the self-development of consciousness.
With this dissolution of his moral judgments always in prospect, why should Bradley, or any idealist, have pursued ethical studies at all?
Since all phases of life were equally necessary to enrich an infinite consciousness, which must know both good and evil in order to merge and to transcend them, he could hardly nurse any intense enthusiasm for a different complexion to be given to the lives of men. His moral pa.s.sion--for he had it, caustic and burning clear--was purely intellectual: it was shame that in England the moral consciousness should have been expressed in systems dialectically so primitive as those of the positivists and utilitarians. He acknowledged, somewhat superciliously, that their hearts were in the right place; yet, if we are to have ethics at all, were not their thoughts in the right place also? They were concerned not with a.n.a.lysis of the moral consciousness but with the conduct of affairs and the reform of inst.i.tutions. The spectacle of human wretchedness profoundly moved them; their minds were bent on transforming society, so that a man"s station and its duties might cease to be what a decayed feudal organisation and an inhuman industrialism had made of them.
They revolted against the miserable condition of the ma.s.ses of mankind, and against the miserable consolations which official religion, or a philosophy like Bradley"s, offered them in their misery. The utilitarians were at least intent on existence and on the course of events; they wished to transform inst.i.tutions to fit human nature better, and to educate human nature by those new inst.i.tutions so that it might better realise its latent capacities. These are matters which a man may modify by his acts and they are therefore the proper concern of the moralist. Were they much to blame if they neglected to define pleasure or happiness and used catch-words, dialectically vague, to indicate a direction of effort politically quite unmistakable? Doubtless their political action, like their philosophical nomenclature, was revolutionary and relied too much on wayward feelings ignorant of their own causes. Revolution, no less than tradition, is but a casual and clumsy expression of human nature in contact with circ.u.mstances; yet pain and pleasure and spontaneous hopes, however foolish, are direct expressions of that contact, and speak for the soul; whereas a man"s station and its duties are purely conventional, and may altogether misrepresent his native capacities. The protest of human nature against the world and its oppressions is the strong side of every rebellion; it was the _moral_ side of utilitarianism, of the rebellion against irrational morality.
Unfortunately the English reformers were themselves idealists of a sort, entangled in the vehicles of perception, and talking about sensations and ideas, pleasures and pains, as if these had been the elements of human nature, or even of nature at large: and only the most meagre of verbal systems, and the most artificial, can be constructed out of such materials. Moreover, they spoke much of pleasure and happiness, and hardly at all of misery and pain: whereas it would have been wiser, and truer to their real inspiration, to have laid all the emphasis on evils to be abated, leaving the good to shape itself in freedom. Suffering is the instant and obvious sign of some outrage done to human nature; without this natural recoil, actual or imminent, no morality would have any sanction, and no precept could be imperative. What silliness to command me to pursue pleasure or to avoid it, if in any case everything would be well! Save for some shadow of dire repentance looming in the distance, I am deeply free to walk as I will. The choice of pleasure for a principle of morals was particularly unfortunate in the British utilitarians; it lent them an air of frivolity absurdly contrary to their true character.
Pleasure might have been a fit enough word in the mouth of Aristippus, a semi-oriental untouched by the least sense of responsibility, or even on the lips of humanists in the eighteenth century, who, however sordid their lives may sometimes have been, could still move in imagination to the music of Mozart, in the landscape of Watteau or of Fragonard. But in the land and age of d.i.c.kens the moral ideal was not so much pleasure as kindness: this tenderer word not only expresses better the motive at work, but it points to the distressing presence of misery in the world, to make natural kindness laborious and earnest, and turn it into a legislative system.
Bradley"s hostility to pleasure was not fanatical: one"s station and its duties might have their agreeable side. "It is probably good for you", he tells us, "to have, say, not less than two gla.s.ses of wine after dinner.
Six on ordinary occasions is perhaps too many; but as to three or four, they are neither one way nor the other." If the voluptuary was condemned, it was for the commonplace reason which a hedonist, too, might invoke, that a life of pleasure soon palls and becomes unpleasant. Bradley"s objection to pleasure was merely speculative: he found it too "abstract".
To call a pleasure when actually felt an abstraction is an exquisite absurdity: but pleasure, in its absolute essence, is certainly simple and indefinable. If instead of enjoying it on the wing, and as an earnest of the soul"s momentary harmony, we attempt to arrest and observe it, we find it strangely dumb; we are not informed by it concerning its occasion, nor carried from it by any logical implication to the natural object in which it might be found. A pure hedonist ought therefore to be rather relieved if all images lapsed from his consciousness and he could luxuriate in sheer pleasure, dark and overwhelming. True, such bliss would be rather inhuman, and of the sort which we rashly a.s.sign to the oyster: but why should a radical and intrepid philosopher be ashamed of that? The condition of Bradley"s Absolute--feeling in which all distinctions are transcended and merged--seems to be something of that kind; but there would be a strange irony in attributing this mystical and rapturous ideal to such ponderous worthies as Mill and Spencer, whose minds were nothing if not anxious, perturbed, instrumental, and full of respect for variegated facts, and who were probably incapable of tasting pure pleasure at all.
But if pleasure, in its pure essence, might really be the highest good for a mystic who should be lost in it, it would be no guide to a moralist wishing to control events, and to distribute particular pleasures or series of pleasures as richly as possible in the world. For this purpose he would need to understand human nature and its variable functions, in which different persons and peoples may find their sincere pleasures; and this knowledge would first lend to his general love of pleasure any point of application in the governance of life or in benevolent legislation.
Some concrete image of a happy human world would take the place of the futile truism that pleasure is good and pain evil. This is, of course, what utilitarian moralists meant to do, and actually did, in so far as their human sympathies extended, which was not to the highest things; but it was not what they said, and Bradley had a clear advantage over them in the war of words. A pleasure is not a programme: it exists here and not there, for me and for no one else, once and never again. When past, it leaves the will as empty and as devoid of allegiance as if it had never existed; pleasure is sand, though it have the colour of gold. But this is evidently true of all existence. Each living moment, each dead man, each cycle of the universe leaves nothing behind it but a void which perhaps something kindred may refill. A Hegel, after identifying himself for a moment with the Absolute Idea, is in his existence no less subject to sleepiness, irritation, and death than if he had been modestly satisfied with the joys of an oyster. It is only their common form, or their common worship, that can give to the quick moments of life any mutual relevance or sympathy; and existence would not come at all within sight of a good, either momentary or final, if it were not inwardly directed upon realising some definite essence. For the rest this essence may be as simple as you will, if the nature directed upon it is unified and simple; and it would be mere intellectual sn.o.bbery to condemn pleasure because it has not so many subdivisions in it as an encyclopaedia of the sciences. For the moralist pleasure and pain may even be the better guides, because they express more directly and boldly the instinctive direction of animal life, and thereby mark more clearly the genuine difference between good and evil.
We may well say with Bradley that the good is self-realisation; but what is the self? Certainly not the feeling or consciousness of the moment, nor the life of the world, nor pure spirit. The self that can systematically distinguish good from evil is an animal soul. It grows from a seed; its potentiality is definite and its fate precarious; and in man it requires society to rear it and tradition to educate it. The good is accordingly social, in so far as the soul demands society; but it is the nature of the individual that determines the kind and degree of sociability that is good for him, and draws the line between society that is a benefit and society that is a nuisance. To subordinate the soul fundamentally to society or the individual to the state is sheer barbarism: the Greeks, sometimes invoked to support this form of idolatry, were never guilty of it; on the contrary, their lawgivers were always reforming and planning the state so that the soul might be perfect in it. Discipline is a help to the spirit: but even social relations, when like love, friendship, or sport they are spontaneous and good in themselves, retire as far as possible from the pressure of the world, and build their paradise apart, simple, and hidden in the wilderness; while all the ultimate hopes and a.s.surances of the spirit escape altogether into the silent society of nature, of truth, of essence, far from those fatuous worldly conventions which hardly make up for their tyranny by their instability: for the prevalent moral fashion is always growing old, and human nature is always becoming young again.
World-worship is the expedient of those who, having lost the soul that is in them, look for it in things external, where there is no soul: and by a curious recoil, it is also the expedient of those who seek their lost soul in actual consciousness, where it also is not: for sensations and ideas are not the soul but only pa.s.sing and partial products of its profound animal life. Moral consciousness in particular would never have arisen and would be gratuitous, save for the ferocious bias of a natural living creature, defending itself against its thousand enemies.
Nor would knowledge in its turn be knowledge if it were merely intuition of essence, such as the sensualist, the poet, or the dialectician may rest in. If the imagery of logic or pa.s.sion ever comes to convey _knowledge_, it does so by virtue of a concomitant physical adjustment to external things; for the nerve of real or transcendent knowledge is the notice which one part of the world may take of another part; and it is this momentous cognisance, no matter what intangible feelings may supply terms for its prosody, that enlarges the mind to some practical purpose and informs it about the world. Consciousness then ceases to be pa.s.sive sense or idle ideation and becomes belief and intelligence. Then the essences which form the "content of consciousness" may be vivified and trippingly run over, like the syllables of a familiar word, in the active recognition of things and people and of all the ominous or pliable forces of nature.
For essences, being eternal and non-existent in themselves, cannot come to consciousness by their own initiative, but only as occasion and the subtle movements of the soul may evoke their forms; so that the fact that they are given to consciousness has a natural status and setting in the material world, and is part of the same natural event as the movement of the soul and body which supports that consciousness.
There is therefore no need of refuting idealism, which is an honest examination of conscience in a reflective mind. Refutations and proofs depend on pregnant meanings a.s.signed to terms, meanings first rendered explicit and unambiguous by those very proofs or refutations. On any different acceptation of those terms, these proofs and refutations fall to the ground; and it remains a question for good sense, not for logic at all, how far the terms in either case describe anything existent. If by "knowledge" we understand intuition of essences, idealism follows; but it follows only in respect to essences given in intuition: nothing follows concerning the seat, origin, conditions, or symptomatic value of such intuition, nor even that such intuition ever actually occurs. Idealism, therefore, without being refuted, may be hemmed in and humanised by natural knowledge about it and about its place in human speculation; the most recalcitrant materialist (like myself) might see its plausibility during a somewhat adolescent phase of self-consciousness. Consciousness itself he might accept and relish as the natural spiritual resonance of action and pa.s.sion, recognising it in its proud isolation and specious autonomy, like the mountain republics of Andorra and San Marino.
German idealism is a mighty pose, an att.i.tude always possible to a self-conscious and reflective being: but it is hardly a system, since it contradicts beliefs which in action are inevitable; it may therefore be readily swallowed, but it can never be digested. Neither of its two ingredients--romantic scepticism and romantic superst.i.tion--agrees particularly with the British stomach. Not romantic scepticism: for in England an instinctive distrust of too much clearness and logic, a difficulty in drawing all the consequences of any principle, soon gave to this most radical of philosophies a prim and religious air: its purity was alloyed with all sorts of conventions: so much so that we find British Hegelians often deeply engaged in psychology, cosmology, or religion, as if they took their idealism for a kind of physics, and wished merely to reinterpret the facts of nature in an edifying way, without uprooting them from their natural places. This has been made easier by giving idealism an objective, non-psychological turn: events, and especially feelings and ideas, will then be swallowed up in the essences which they display. Thus Bradley maintained that two thoughts, no matter how remote from each other in time or s.p.a.ce, were identically the same, and not merely similar, if only they contemplated the same idea. Mind itself ceased in this way to mean a series of existing feelings and was identified with intelligence; and intelligence in its turn was identified with the Idea or Logos which might be the ultimate theme of intelligence. There could be only one mind, so conceived, since there could be only one total system in the universe visible to omniscience.
As to romantic scepticism, we may see by contrast what it would be, when left to itself, if we consider those lucid Italians who have taken up their idealism late and with open eyes. In Croce and Gentile the transcendental att.i.tude is kept pure: for them there is really no universe save spirit creating its experience; and if we ask whence or on what principle occasions arise for all this compulsory fiction, we are reminded that this question, with any answer which spirit might invent for it, belongs not to philosophy but to some special science like physiology, itself, of course, only a particular product of creative thought. Thus the more impetuously the inquisitive squirrel would rush from his cage, the faster and faster he causes the cage to whirl about his ears. He has not the remotest chance of reaching his imaginary bait--G.o.d, nature, or truth; for to seek such things is to presuppose them, and to presuppose anything, if spirit be absolute, is to invent it. Even those philosophies of history which the idealist may for some secret reason be impelled to construct would be superst.i.tious, according to his own principles, if he took them for more than poetic fictions of the historian; so that in the study of history, as in every other study, all the diligence and sober learning which the philosopher may possess are non-philosophical, since they presuppose independent events and material doc.u.ments. Thus perfect idealism turns out to be pure literary sport, like lyric poetry, in which no truth is conveyed save the miscellaneous truths taken over from common sense or the special sciences; and the gay spirit, supposed to be living and shining of its own sweet will, can find nothing to live or shine upon save the common natural world.
Such at least would be the case if romantic superst.i.tion did not supervene, demanding that the spirit should impose some arbitrary rhythm or destiny on the world which it creates: but this side of idealism has been cultivated chiefly by the intrepid Germans: some of them, like Spengler and Keyserling, still thrive and grow famous on it without a blush. The modest English in these matters take shelter under the wing of science speculatively extended, or traditional religion prudently rationalised: the scope of the spirit, like its psychological distribution, is conceived realistically. It might almost prove an euthanasia for British idealism to lose itself in the new metaphysics of nature which the mathematicians are evolving; and since this metaphysics, though materialistic in effect, is more subtle and abstruse than popular materialism, British idealism might perhaps be said to survive in it, having now pa.s.sed victoriously into its opposite, and being merged in something higher.

REVOLUTIONS IN SCIENCE
Since the beginning of the twentieth century, science has gained notably in expertness, and lost notably in authority. We are bombarded with inventions; but if we ask the inventors what they have learned of the depths of nature, which somehow they have probed with such astonishing success, their faces remain blank. They may be chewing gum; or they may tell us that if an aeroplane could only fly fast enough, it would get home before it starts; or they may urge us to come with them into a dark room, to hold hands, and to commune with the dear departed.
Practically there may be no harm in such a division of labour, the inventors doing the work and the professors the talking. The experts may themselves be inexpert in verbal expression, or content with stock phrases, or profoundly sceptical, or too busy to think. Nevertheless, skill and understanding are at their best when they go together and adorn the same mind. Modern science until lately had realised this ideal: it was an extension of common perception and common sense. We could trust it implicitly, as we do a map or a calendar; it was not true for us merely in an argumentative or visionary sense, as are religion and philosophy.
Geography went hand in hand with travel, Copernican astronomy with circ.u.mnavigation of the globe: and even the theory of evolution and the historical sciences in the nineteenth century were continuous with liberal reform: people saw in the past, as they then learned to conceive it, simply an extension of those transformations which they were witnessing in the present. They could think they knew the world as a man knows his native town, or the contents of his chest of drawers: nature was our home, and science was our home knowledge. For it is not intrinsic clearness or coherence that make ideas persuasive, but connection with action, or with some voluminous inner response, which is readiness to act. It is a sense of on-coming fate, a compulsion to do or to suffer, that produces the illusion of perfect knowledge.
I call it illusion, although our contact with things may be real, and our sensations and thoughts may be inevitable and honest; because nevertheless it is always an illusion to suppose that our images are the intrinsic qualities of things, or reproduce them exactly. The Ptolemaic system, for instance, was perfectly scientific; it was based on careful and prolonged observation and on just reasoning; but it was modelled on an image--the spherical blue dome of the heavens--proper only to an observer on the earth, and not transferable to a universe which is diffuse, centreless, fluid, and perhaps infinite. When the imagination, for any reason, comes to be peopled with images of the latter sort, the modern, and especially the latest, astronomy becomes more persuasive. For although I suspect that even Einstein is an imperfect relativist, and retains Euclidean s.p.a.ce and absolute time at the bottom of his calculation, and recovers them at the end, yet the effort to express the system of nature as it would appear from _any_ station and to _any_ sensorium seems to be eminently enlightening.
Theory and practice in the latest science are still allied, otherwise neither of them would prosper as it does; but each has taken a leap in its own direction. The distance between them has become greater than the naked eye can measure, and each of them in itself has become unintelligible. We roll and fly at dizzy speeds, and hear at incredible distances; at the same time we imagine and calculate to incredible depths. The technique of science, like that of industry, has become a thing in itself; the one veils its object, which is nature, as the other defeats its purpose, which is happiness. Science often seems to be less the study of things than the study of science. It is now more scholastic than philosophy ever was. We are invited to conceive organisms within organisms, so minute, so free, and so dynamic, that the heart of matter seems to explode into an endless discharge of fireworks, or a mathematical nightmare realised in a thousand places at once, and become the substance of the world. What is even more remarkable--for the notion of infinite organisation has been familiar to the learned at least since the time of Leibniz--the theatre of science is transformed no less than the actors and the play. The upright walls of s.p.a.ce, the steady tread of time, begin to fail us; they bend now so obligingly to our perspectives that we no longer seem to travel through them, but to carry them with us, shooting them out or weaving them about us according to some native fatality, which is left unexplained. We seem to have reverted in some sense from Copernicus to Ptolemy: except that the centre is now occupied, not by the solid earth, but by _any_ geometrical point chosen for the origin of calculation. Time, too, is not measured by the sun or stars, but by _any_ "clock"--that is, by any recurrent rhythm taken as a standard of comparison. It would seem that the existence and energy of each chosen centre, as well as its career and encounters, hang on the collateral existence of other centres of force, among which it must wend its way: yet the only witness to their presence, and the only known property of their substance, is their "radio-activity", or the physical light which they shed. Light, in its physical being, is accordingly the measure of all things in this new philosophy: and if we ask ourselves why this element should have been preferred, the answer is not far to seek.
Light is the only medium through which very remote or very minute particles of matter can be revealed to science. Whatever the nature of things may be intrinsically, science must accordingly express the universe in terms of light.
These reforms have come from within: they are triumphs of method. We make an evident advance in logic, and in that parsimony which is dear to philosophers (though not to nature), if we refuse to a.s.sign given terms and relations to any prior medium, such as absolute time or s.p.a.ce, which cannot be given with them. Observable s.p.a.ces and times, like the facts observed in them, are given separately and in a desultory fashion.
Initially, then, there are as many s.p.a.ces and times as there are observers, or rather observations; these are the specious times and s.p.a.ces of dreams, of sensuous life, and of romantic biography. Each is centred here and now, and stretched outwards, forward, and back, as far as imagination has the strength to project it. Then, when objects and events have been posited as self-existent, and when a "clock" and a system of co-ordinates have been established for measuring them, a single mathematical s.p.a.ce and time may be deployed about them, conceived to contain all things, and to supply them with their respective places and dates. This gives us the cosmos of cla.s.sical physics. But this system involves the uncritical notion of light and matter travelling through media previously existing, and being carried down, like a boat drifting down stream, by a flowing time which has a pace of its own, and imposes it on all existence. In reality, each "clock" and each landscape is self-centred and initially absolute: its time and s.p.a.ce are irrelevant to those of any other landscape or "clock", unless the objects or events revealed there, being posited as self-existent, actually coincide with those revealed also in another landscape, or dated by another "clock". It is only by travelling along its own path at its own rate that experience or light can ever reach a point lying on another path also, so that two observations, and two measures, may coincide at their ultimate terms, their starting-points or their ends. Positions are therefore not independent of the journey which terminates in them, and thereby individuates them; and dates are not independent of the events which distinguish them. The flux of existence comes first: matter and light distend time by their pulses, they distend s.p.a.ce by their deployments.
This, if I understand it, is one half the new theory; the other half is not less acceptable. Newton had described motion as a result of two principles: the first, inertia, was supposed to be inherent in bodies; the second, gravity, was incidental to their co-existence. Yet inherent inertia can only be observed relatively: it makes no difference to me whether I am said to be moving at a great speed or absolutely at rest, if I am not jolted or breathless, and if my felt environment does not change.
Inertia, or weight, in so far as it denotes something intrinsic, seems to be but another name for substance or the principle of existence: in so far as it denotes the first law of motion, it seems to be relative to an environment. It would therefore be preferable to combine inertia and attraction in a single formula, expressing the behaviour of bodies towards one another in all their conjunctions, without introducing any inherent forces or absolute measures. This seems to have been done by Einstein, or at least impressively suggested: and it has been found that the new calculations correspond to certain delicate observations more accurately than the old.
This revolution in science seems, then, to be perfectly legal, and ought to be welcomed; yet only under one important moral condition, and with a paradoxical result. The moral condition is that the pride of science should turn into humility, that it should no longer imagine that it is laying bare the intrinsic nature of things. And the paradoxical result is this: that the forms of science are optional, like various languages or methods of notation. One may be more convenient or subtle than another, according to the place, senses, interests, and scope of the explorer; a reform in science may render the old theories antiquated, like the habit of wearing togas, or of going naked; but it cannot render them false, or itself true. Science, when it is more than the gossip of adventure or of experiment, yields practical a.s.surances couched in symbolic terms, but no ultimate insight: so that the intellectual vacancy of the expert, which I was deriding, is a sort of warrant of his solidity. It is rather when the expert prophesies, when he propounds a new philosophy founded on his latest experiments, that we may justly smile at his system, and wait for the next.
Self-knowledge--and the new science is full of self-knowledge--is a great liberator: if perhaps it imposes some retrenchment, essentially it revives courage. Then at last we see what we are and what we can do. The spirit can abandon its vain commitments and false pretensions, like a young man free at last to throw off his clothes and run naked along the sands.
Intelligence is never gayer, never surer, than when it is strictly formal, satisfied with the evidence of its materials, as with the lights of jewels, and filled with mounting speculations, as with a sort of laughter.
If all the arts aspire to the condition of music, all the sciences aspire to the condition of mathematics. Their logic is their spontaneous and intelligible side: and while they differ from mathematics and from one another in being directed in the first instance upon various unintelligible existing objects, yet as they advance, they unite: because they are everywhere striving to discover in those miscellaneous objects some intelligible order and method. And as the emotion of the pure artist, whatever may be his materials, lies in finding in them some formal harmony or imposing it upon them, so the interest of the scientific mind, in so far as it is free and purely intellectual, lies in tracing their formal pattern. The mathematician can afford to leave to his clients, the engineers, or perhaps the popular philosophers, the emotion of belief: for himself he keeps the lyrical pleasure of metre and of evolving equations: and it is a pleasant surprise to him, and an added problem, if he finds that the arts can use his calculations, or that the senses can verify them; much as if a composer found that the sailors could heave better when singing his songs.
Yet such independence, however glorious inwardly, cannot help diminishing the prestige of the arts in the world. If science misled us before, when it was full of clearness and confidence, how shall we trust it now that it is all mystery and paradox? If cla.s.sical physics needed this fundamental revision, near to experience and fruitful as it was, what revision will not romantic physics require? Nor is the future alone insecure: even now the prophets hardly understand one another, or perhaps themselves; and some of them interlard their science with the most dubious metaphysics.
Naturally the enemies of science have not been slow to seize this opportunity: the soft-hearted, the muddle-headed, the superst.i.tious are all raising their voices, no longer in desperate resistance to science, but hopefully, and in its name. Science, they tell us, is no longer hostile to religion, or to divination of any sort. Indeed, divination is a science too. Physics is no longer materialistic since s.p.a.ce is now curved, and filled with an ether through which light travels at 300,000 kilometres per second--an immaterial rate: because if anything material ventured to move at that forbidden speed, it would be so flattened that it would cease to exist. Indeed, matter is now hardly needed at all; its place has been taken by radio-activity, and by electrons which dart and whirl with such miraculous swiftness, that occasionally, for no known reason, they can skip from orbit to orbit without traversing the intervening positions--an evident proof of free-will in them. Or if solids should still seem to be material, there are astral bodies as well which are immaterial although physical; and as to ether and electricity, they are the very substance of spirit. All this I find announced in newspapers and even in books as the breakdown of scientific materialism: and yet, when was materialism more arrant and barbarous than in these announcements? Something no doubt has broken down: but I am afraid it is rather the habit of thinking clearly and the power to discern the difference between material and spiritual things.
The latest revolution in science will probably not be the last. I do not know what internal difficulties, contradictions, or ominous obscurities may exist in the new theories, or what logical seeds of change, perhaps of radical change, might be discovered there by a competent critic. I base my expectation on two circ.u.mstances somewhat more external and visible to the lay mind. One circ.u.mstance is that the new theories seem to be affected, and partly inspired, by a particular philosophy, itself utterly insecure.
This philosophy regards the point of view as controlling or even creating the object seen; in other words, it identifies the object with the experience or the knowledge of it: it is essentially a subjective, psychological, Protestant philosophy. The study of perspectives, which a severer critic might call illusions, is one of the most interesting and enlightening of studies, and for my own part I should be content to dwell almost exclusively in that poetic and moral atmosphere, in the realm of literature and of humanism. Yet I cannot help seeing that neither in logic nor in natural genesis can perspectives be the ultimate object of science, since a plurality of points of view, somehow comparable, must be a.s.sumed in the beginning, as well as common principles of projection, and ulterior points of contact or coincidence. Such a.s.sumptions, which must persist throughout, seem to presuppose an absolute system of nature behind all the relative systems of science.
The other circ.u.mstance which points to further revolutions is social. The new science is unintelligible to almost all of us; it can be tested only by very delicate observations and very difficult reasoning. We accept it on the authority of a few professors who themselves have accepted it with a contagious alacrity, as if caught in a whirlwind. It has sprung up mysteriously and mightily, like mysticism in a cloister or theology in a council: a Soviet of learned men has proclaimed it. Moreover, it is not merely a system among systems, but a movement among movements. A system, even when it has serious rivals, may be maintained for centuries as religions are maintained, inst.i.tutionally; but a movement comes to an end; it is followed presently by a period of a.s.similation which transforms it, or by a movement in some other direction. I ask myself accordingly whether the condition of the world in the coming years will be favourable to refined and paradoxical science. The extension of education will have enabled the uneducated to p.r.o.nounce upon everything. Will the patronage of capital and enterprise subsist, to encourage discovery and reward invention? Will a jealous and dogmatic democracy respect the unintelligible insight of the few? Will a perhaps starving democracy support materially its Soviet of seers? But let us suppose that no utilitarian fanaticism supervenes, and no intellectual surfeit or discouragement. May not the very profundity of the new science and its metaphysical affinities lead it to bolder developments, inscrutable to the public and incompatible with one another, like the gnostic sects of declining antiquity? Then perhaps that luminous modern thing which until recently was called science, in contrast to all personal philosophies, may cease to exist altogether, being petrified into routine in the pract.i.tioners, and fading in the professors into abstruse speculations.

A LONG WAY ROUND TO NIRVANA
That the end of life is death may be called a truism, since the various kinds of immortality that might perhaps supervene would none of them abolish death, but at best would weave life and death together into the texture of a more comprehensive destiny. The end of one life might be the beginning of another, if the Creator had composed his great work like a dramatic poet, a.s.signing successive lines to different characters. Death would then be merely the cue at the end of each speech, summoning the next personage to break in and keep the ball rolling. Or perhaps, as some suppose, all the characters are a.s.sumed in turn by a single supernatural Spirit, who amid his endless improvisations is imagining himself living for the moment in this particular solar and social system. Death in such a universal monologue would be but a change of scene or of metre, while in the scramble of a real comedy it would be a change of actors. In either case every voice would be silenced sooner or later, and death would end each particular life, in spite of all possible sequels.
The relapse of created things into nothing is no violent fatality, but something naturally quite smooth and proper. This has been set forth recently, in a novel way, by a philosopher from whom we hardly expected such a lesson, namely Professor Sigmund Freud. He has now broadened his conception of s.e.xual craving or _libido_ into a general principle of attraction or concretion in matter, like the Eros of the ancient poets Hesiod and Empedocles. The windows of that stuffy clinic have been thrown open; that smell of acrid disinfectants, those hysterical shrieks, have escaped into the cold night. The troubles of the sick soul, we are given to understand, as well as their cure, after all flow from the stars.
I am glad that Freud has resisted the tendency to represent this principle of Love as the only principle in nature. Unity somehow exercises an evil spell over metaphysicians. It is admitted that in real life it is not well for One to be alone, and I think pure unity is no less barren and graceless in metaphysics. You must have plurality to start with, or trinity, or at least duality, if you wish to get anywhere, even if you wish to get effectively into the bosom of the One, abandoning your separate existence. Freud, like Empedocles, has prudently introduced a prior principle for Love to play with; not Strife, however (which is only an incident in Love), but Inertia, or the tendency towards peace and death. Let us suppose that matter was originally dead, and perfectly content to be so, and that it still relapses, when it can, into its old equilibrium. But the h.o.m.ogeneous (as Spencer would say) when it is finite is unstable: and matter, presumably not being co-extensive with s.p.a.ce, necessarily forms aggregates which have an inside and an outside. The parts of such bodies are accordingly differently exposed to external influences and differently related to one another. This inequality, even in what seems most quiescent, is big with changes, destined to produce in time a wonderful complexity. It is the source of all uneasiness, of life, and of love.
"Let us imagine [writes Freud][11] an undifferentiated vesicle of sensitive substance: then its surface, exposed as it is to the outer world, is by its very position differentiated, and serves as an organ for receiving stimuli.... This morsel of living substance floats about in an outer world which is charged with the most potent energies, and it would be destroyed ... if it were not furnished with protection against stimulation.
