Language, then, with the logic imbedded in it, is a repository of terms formed by identifying successive perceptions, as the external world is a repository of objects conceived by superposing perceptions that exist together. Being formed on different principles these two orders of conception—the logical and the physical—do not coincide, and the attempt to fuse them into one system of demonstrable reality or moral physics is doomed to failure by the very nature of the terms compared. When the Eleatics proved the impossibility—i.e., the inexpressibility—of motion, or when Kant and his followers proved the unreal character of all objects of experience and of all natural knowledge, their task was made easy by the native diversity between the concretions in existence which were the object of their thought and the concretions in discourse which were its measure. The two do not fit; and intrenched as these philosophers were in the forms of logic they compelled themselves to reject as unthinkable everything not fully expressible in those particular forms. Thus they took their revenge upon the vulgar who, being busy chiefly with material things and dwelling in an atmosphere of sensuous images, call unreal and abstract every product of logical construction or reflective analysis. These logical products, however, are not really abstract, but, as we have seen, concretions arrived at by a different method than that which results in material conceptions. Whereas the conception of a thing is a local conglomerate of several simultaneous sensations, logical entity is a homogeneous revival in memory of similar sensations temporally distinct.
Thus the many armed with prejudice and the few armed with logic fight an eternal battle, the logician charging the physical world with unintelligibility and the man of common-sense charging the logical world with abstractness and unreality. The former view is the more profound, since association by similarity is the more elementary and gives constancy to meanings; while the latter view is the more practical, since association by contiguity alone informs the mind about the mechanical sequence of its own experience. Neither principle can be dispensed with, and each errs only in denouncing the other and wishing to be omnivorous, as if on the one hand logic could make anybody understand the history of events and the conjunction of objects, or on the other hand as if cognitive and moral processes could have any other terms than constant and ideal natures. The namable essence of things or the standard of values must always be an ideal figment; existence must always be an empirical fact. The former remains always remote from natural existence and the latter irreducible to a logical principle.[C]
[A] This distinction, in one sense, is Platonic: but Plato’s Reason was distinguished from understanding (which dealt with phenomenal experience) because it was a moral faculty defining those values and meanings which in Platonic nomenclature took the title of reality. The German Reason was only imagination, substituting a dialectical or poetic history of the world for its natural development. German idealism, accordingly, was not, like Plato’s, a moral philosophy hypostasised but a false physics adored.
[B] This natural order and affinity is something imputed to the ultimate object of thought—the reality—by the last act of judgment assuming its own truth. It is, of course, not observable by consciousness before the first experiment in comprehension has been made; the act of comprehension which first imposes on the sensuous material some subjective category is the first to arrive at the notion of an objective order. The historian, however, has a well-tried and mature conception of the natural order arrived at after many such experiments in comprehension. From the vantage-ground of this latest hypothesis, he surveys the attempts others have made to understand events and compares them with the objective order which he believes himself to have discovered. This observation is made here lest the reader should confuse the natural order, imagined to exist before any application of human categories, with the last conception of that order attained by the philosopher. The latter is but faith, the former is faith’s ideal object.
[C] For the sake of simplicity only such ideas as precede conceptions of things have been mentioned here. After things are discovered, however, they may be used as terms in a second ideal synthesis and a concretion in discourse on a higher plane may be composed out of sustained concretions in existence. Proper names are such secondary concretions in discourse. “Venice” is a term covering many successive aspects and conditions, not distinguished in fancy, belonging to an object existing continuously in space and time. Each of these states of Venice constitutes a natural object, a concretion in existence, and is again analysable into a mass of fused but recognisable qualities—light, motion, beauty—each of which was an original concretion in discourse, a primordial term in experience. A quality is recognised by its own idea or permanent nature, a thing by its constituent qualities, and an embodied spirit by fusion into an ideal essence of the constant characters possessed by a thing. To raise natural objects into historic entities it is necessary to repeat upon a higher plane that concretion in discourse by which sensations were raised to ideas. When familiar objects attain this ideal character they have become poetical and achieved a sort of personality. They then possess a spiritual status. Thus sensuous experience is solidified into logical terms, these into ideas of things, and these, recast and smelted again in imagination, into forms of spirit.
CHAPTER VIII—ON THE RELATIVE VALUE OF THINGS AND IDEAS
Those who look back upon the history of opinion for many centuries commonly feel, by a vague but profound instinct, that certain consecrated doctrines have an inherent dignity and spirituality, while other speculative tendencies and other vocabularies seem wedded to all that is ignoble and shallow. So fundamental is this moral tone in philosophy that people are usually more firmly convinced that their opinions are precious than that they are true. They may avow, in reflective moments, that they may be in error, seeing that thinkers of no less repute have maintained opposite opinions, but they are commonly absolutely sure that if their own views could be generally accepted, it would be a boon to mankind, that in fact the moral interests of the race are bound up, not with discovering what may chance to be true, but with discovering the truth to have a particular complexion. This predominant trust in moral judgments is in some cases conscious and avowed, so that philosophers invite the world to embrace tenets for which no evidence is offered but that they chime in with current aspirations or traditional bias. Thus the substance of things hoped for becomes, even in philosophy, the evidence of things not seen.
Such faith is indeed profoundly human and has accompanied the mind in all its gropings and discoveries; preference being the primary principle of discrimination and attention. Reason in her earliest manifestations already discovered her affinities and incapacities, and loaded the ideas she framed with friendliness or hostility. It is not strange that her latest constructions should inherit this relation to the will; and we shall see that the moral tone and affinity of metaphysical systems corresponds exactly with the primary function belonging to that type of idea on which they are based. Idealistic systems, still cultivating concretions in discourse, study the first conditions of knowledge and the last interests of life; materialistic systems, still emphasising concretions in existence, describe causal relations, and the habits of nature. Thus the spiritual value of various philosophies rests in the last instance on the kind of good which originally attached the mind to that habit and plane of ideation.
We have said that perceptions must be recognised before they can be associated by contiguity, and that consequently the fusion of temporally diffused experiences must precede their local fusion into material objects. It might be urged in opposition to this statement that concrete objects can be recognised in practice before their general qualities have been distinguished in discourse. Recognition may be instinctive, that is, based on the repetition of a felt reaction or emotion, rather than on any memory of a former occasion on which the same perception occurred. Such an objection seems to be well grounded, for it is instinctive adjustments and suggested action that give cognitive value to sensation and endow it with that transitive force which makes it consciously representative of what is past, future, or absent. If practical instinct did not stretch what is given into what is meant, reason could never recognise the datum for a copy of an ideal object.
This description of the case involves an application or extension of our theory rather than an argument against it. For where recognition is instinctive and a familiar action is performed with absent-minded confidence and without attending to the indications that justify that action, there is in an eminent degree a qualitative concretion in experience. Present impressions are merged so completely in structural survivals of the past that instead of arousing any ideas distinct enough to be objectified they merely stimulate the inner sense, remain imbedded in the general feeling of motion or life, and constitute in fact a heightened sentiment of pure vitality and freedom. For the lowest and vaguest of concretions in discourse are the ideas of self and of an embosoming external being, with the felt continuity of both; what Fichte would call the Ego, the Non-Ego, and Life. Where no particular events are recognised there is still a feeling of continuous existence. We trail after us from our whole past some sense of the continuous energy and movement both of our passionate fancies and of the phantasmagoria capriciously at work beyond. An ignorant mind believes itself omniscient and omnipotent; those impulses in itself which really represent the inertia and unspent momentum of its last dream it regards as the creative forces of nature.
The first lines of cleavage and the first recognisable bulks at which attention is arrested are in truth those shadowy Fichtean divisions: such are the rude beginnings of logical architecture. In its inability to descry anything definite and fixed, for want of an acquired empirical background and a distinct memory, the mind flounders forward in a dream full of prophecies and wayward identifications. The world possesses as yet in its regard only the superficial forms that appear in revery, it has no hidden machinery, no third dimension in which unobserved and perpetual operations are going on. Its only terms, in a word, are concretions in discourse, ideas combined in their æsthetic and logical harmonies, not in their habitual and efficacious conjunctions. The disorder of such experience is still a spontaneous disorder; it has not discovered how calculable are its unpremeditated shocks. The cataclysms that occur seem to have only ideal grounds and only dramatic meaning. Though the dream may have its terrors and degenerate at moments into a nightmare, it has still infinite plasticity and buoyancy. What perceptions are retained merge in those haunting and friendly presences, they have an intelligible and congenial character because they appear as parts and effluences of an inner fiction, evolving according to the barbaric prosody of an almost infant mind.
This is the fairy-land of idealism where only the miraculous seems a matter of course and every hint of what is purely natural is disregarded, for the truly natural still seems artificial, dead, and remote. New and disconcerting facts, which intrude themselves inopportunely into the story, chill the currents of spontaneous imagination and are rejected as long as possible for being alien and perverse. Perceptions, on the contrary, which can be attached to the old presences as confirmations or corollaries, become at once parts of the warp and woof of what we call ourselves. They seem of the very substance of spirit, obeying a vital momentum and flowing from the inmost principle of being; and they are so much akin to human presumptions that they pass for manifestations of necessary truth. Thus the demonstrations of geometry being but the intent explication of a long-consolidated ideal concretion which we call space, are welcomed by the mind as in a sense familiar and as revelations of a truth implicit in the soul, so that Plato could plausibly take them for recollections of prenatal wisdom. But a rocket that bursts into sparks of a dozen colours, even if expected, is expected with anxiety and observed with surprise; it assaults the senses at an incalculable moment with a sensation individual and new. The exciting tension and lively stimulus may please in their way, yet the badge of the accidental and unmeaning adheres to the thing. It is a trivial experience and one quickly forgotten. The shock is superficial and were it repeated would soon fatigue. We should retire with relief into darkness and silence, to our permanent and rational thoughts.
It is a remarkable fact, which may easily be misinterpreted, that while all the benefits and pleasures of life seem to be associated with external things, and all certain knowledge seems to describe material laws, yet a deified nature has generally inspired a religion of melancholy. Why should the only intelligible philosophy seem to defeat reason and the chief means of benefiting mankind seem to blast our best hopes? Whence this profound aversion to so beautiful and fruitful a universe? Whence this persistent search for invisible regions and powers and for metaphysical explanations that can explain nothing, while nature’s voice without and within man cries aloud to him to look, act, and enjoy? And when someone, in protest against such senseless oracular prejudices, has actually embraced the life and faith of nature and taught others to look to the natural world for all motives and sanctions, expecting thus to refresh and marvellously to invigorate human life, why have those innocent hopes failed so miserably? Why is that sensuous optimism we may call Greek, or that industrial optimism we may call American, such a thin disguise for despair? Why does each melt away and become a mockery at the first approach of reflection? Why has man’s conscience in the end invariably rebelled against naturalism and reverted in some form or other to a cultus of the unseen?
We may answer in the words of Saint Paul: because things seen are temporal and things not seen are eternal. And we may add, remembering our analysis of the objects inhabiting the mind, that the eternal is the truly human, that which is akin to the first indispensable products of intelligence, which arise by the fusion of successive images in discourse, and transcend the particular in time, peopling the mind with permanent and recognisable objects, and strengthening it with a synthetic, dramatic apprehension of itself and its own experience. Concretion in existence, on the contrary, yields essentially detached and empirical unities, foreign to mind in spite of their order, and unintelligible in spite of their clearness. Reason fails to assimilate in them precisely that which makes them real, namely, their presence here and now, in this order and number. The form and quality of them we can retain, domesticate, and weave into the texture of reflection, but their existence and individuality remain a datum of sense needing to be verified anew at every moment and actually receiving continual verification or disproof while we live in this world.
“This world” we call it, not without justifiable pathos, for many other worlds are conceivable and if discovered might prove more rational and intelligible and more akin to the soul than this strange universe which man has hitherto always looked upon with increasing astonishment. The materials of experience are no sooner in hand than they are transformed by intelligence, reduced to those permanent presences, those natures and relations, which alone can live in discourse. Those materials, rearranged into the abstract summaries we call history or science, or pieced out into the reconstructions and extensions we call poetry or religion, furnish us with ideas of as many dream-worlds as we please, all nearer to reason’s ideal than is the actual chaos of perceptual experience, and some nearer to the heart’s desire. When an empirical philosophy, therefore, calls us back from the irresponsible flights of imagination to the shock of sense and tries to remind us that in this alone we touch existence and come upon fact, we feel dispossessed of our nature and cramped in our life. The actuality possessed by external experience cannot make up for its instability, nor the applicability of scientific principles for their hypothetical character. The dependence upon sense, which we are reduced to when we consider the world of existences, becomes a too plain hint of our essential impotence and mortality, while the play of logical fancy, though it remain inevitable, is saddened by a consciousness of its own insignificance.
That dignity, then, which inheres in logical ideas and their affinity to moral enthusiasm, springs from their congruity with the primary habits of intelligence and idealisation. The soul or self or personality, which in sophisticated social life is so much the centre of passion and concern, is itself an idea, a concretion in discourse; and the level on which it swims comes to be, by association and affinity, the region of all the more vivid and massive human interests. The pleasures which lie beneath it are ignored, and the ideals which lie above it are not perceived. Aversion to an empirical or naturalistic philosophy accordingly expresses a sort of logical patriotism and attachment to homespun ideas. The actual is too remote and unfriendly to the dreamer; to understand it he has to learn a foreign tongue, which his native prejudice imagines to be unmeaning and unpoetical. The truth is, however, that nature’s language is too rich for man; and the discomfort he feels when he is compelled to use it merely marks his lack of education. There is nothing cheaper than idealism. It can be had by merely not observing the ineptitude of our chance prejudices, and by declaring that the first rhymes that have struck our ear are the eternal and necessary harmonies of the world.
The thinker’s bias is naturally favourable to logical ideas. The man of reflection will attribute, as far as possible, validity and reality to these alone. Platonism remains the classic instance of this way of thinking. Living in an age of rhetoric, with an education that dealt with nothing but ideal entities, verbal, moral, or mathematical, Plato saw in concretions in discourse the true elements of being. Definable meanings, being the terms of thought, must also, he fancied, be the constituents of reality. And with that directness and audacity which was possible to the ancients, and of which Pythagoreans and Eleatics had already given brilliant examples, he set up these terms of discourse, like the Pythagorean numbers, for absolute and eternal entities, existing before all things, revealed in all things, giving the cosmic artificer his models and the creature his goal. By some inexplicable necessity the creation had taken place. The ideas had multiplied themselves in a flux of innumerable images which could be recognised by their resemblance to their originals, but were at once cancelled and expunged by virtue of their essential inadequacy. What sounds are to words and words to thoughts, that was a thing to its idea.
Plato, however, retained the moral and significant essence of his ideas, and while he made them ideal absolutes, fixed meanings antecedent to their changing expressions, never dreamed that they could be natural existences, or psychological beings. In an original thinker, in one who really thinks and does not merely argue, to call a thing supernatural, or spiritual, or intelligible is to declare that it is no thing at all, no existence actual or possible, but a value, a term of thought, a merely ideal principle; and the more its reality in such a sense is insisted on the more its incommensurability with brute existence is asserted. To express this ideal reality myth is the natural vehicle; a vehicle Plato could avail himself of all the more freely that he inherited a religion still plastic and conscious of its poetic essence, and did not have to struggle, like his modern disciples, with the arrested childishness of minds that for a hundred generations have learned their metaphysics in the cradle. His ideas, although their natural basis was ignored, were accordingly always ideal; they always represented meanings and functions and were never degraded from the moral to the physical sphere. The counterpart of this genuine ideality was that the theory retained its moral force and did not degenerate into a bewildered and idolatrous pantheism. Plato conceived the soul’s destiny to be her emancipation from those material things which in this illogical apparition were so alien to her essence. She should return, after her baffling and stupefying intercourse with the world of sense and accident, into the native heaven of her ideas. For animal desires were no less illusory, and yet no less significant, than sensuous perceptions. They engaged man in the pursuit of the good and taught him, through disappointment, to look for it only in those satisfactions which can be permanent and perfect. Love, like intelligence, must rise from appearance to reality, and rest in that divine world which is the fulfilment of the human.
A geometrician does a good service when he declares and explicates the nature of the triangle, an object suggested by many casual and recurring sensations. His service is not less real, even if less obvious, when he arrests some fundamental concretion in discourse, and formulates the first principles of logic. Mastering such definitions, sinking into the dry life of such forms, he may spin out and develop indefinitely, in the freedom of his irresponsible logic, their implications and congruous extensions, opening by his demonstration a depth of knowledge which we should otherwise never have discovered in ourselves. But if the geometer had a fanatical zeal and forbade us to consider space and the triangles it contains otherwise than as his own ideal science considers them: forbade us, for instance, to inquire how we came to perceive those triangles or that space; what organs and senses conspired in furnishing the idea of them; what material objects show that character, and how they came to offer themselves to our observation—then surely the geometer would qualify his service with a distinct injury and while he opened our eyes to one fascinating vista would tend to blind them to others no less tempting and beautiful. For the naturalist and psychologist have also their rights and can tell us things well worth knowing; nor will any theory they may possibly propose concerning the origin of spatial ideas and their material embodiments ever invalidate the demonstrations of geometry. These, in their hypothetical sphere, are perfectly autonomous and self-generating, and their applicability to experience will hold so long as the initial images they are applied to continue to abound in perception.
If we awoke to-morrow in a world containing nothing but music, geometry would indeed lose its relevance to our future experience; but it would keep its ideal cogency, and become again a living language if any spatial objects should ever reappear in sense.
The history of such reappearances—natural history—is meantime a good subject for observation and experiment. Chronicler and critic can always approach experience with a method complementary to the deductive methods pursued in mathematics and logic: instead of developing the import of a definition, he can investigate its origin and describe its relation to other disparate phenomena. The mathematician develops the import of given ideas; the psychologist investigates their origin and describes their relation to the rest of human experience. So the prophet develops the import of his trance, and the theologian the import of the prophecy: which prevents not the historian from coming later and showing the origin, the growth, and the possible function of that maniacal sort of wisdom. True, the theologian commonly dreads a critic more than does the geometer, but this happens only because the theologian has probably not developed the import of his facts with any austerity or clearness, but has distorted that ideal interpretation with all sorts of concessions and side-glances at other tenets to which he is already pledged, so that he justly fears, when his methods are exposed, that the religious heart will be alienated from him and his conclusions be left with no foothold in human nature. If he had not been guilty of such misrepresentation, no history or criticism that reviewed his construction would do anything but recommend it to all those who found in themselves the primary religious facts and religious faculties which that construction had faithfully interpreted in its ideal deductions and extensions. All who perceived the facts would thus learn their import; and theology would reveal to the soul her natural religion, just as Euclid reveals to architects and navigators the structure of natural space, so that they value his demonstrations not only for their hypothetical cogency but for their practical relevance and truth.
Now, like the geometer and ingenuous theologian that he was, Plato developed the import of moral and logical experience. Even his followers, though they might give rein to narrower and more fantastic enthusiasms, often unveiled secrets, hidden in the oracular intent of the heart, which might never have been disclosed but for their lessons. But with a zeal unbecoming so well grounded a philosophy they turned their backs upon the rest of wisdom, they disparaged the evidence of sense, they grew hot against the ultimate practical sanctions furnished by impulse and pleasure, they proscribed beauty in art (where Plato had proscribed chiefly what to a fine sensibility is meretricious ugliness), and in a word they sought to abolish all human activities other than the one pre-eminent in themselves. In revenge for their hostility the great world has never given them more than a distrustful admiration and, confronted daily by the evident truths they denied, has encouraged itself to forget the truths they asserted. For they had the bias of reflection and man is born to do more than reflect; they attributed reality and validity only to logical ideas, and man finds other objects continually thrusting themselves before his eyes, claiming his affection and controlling his fortunes.
The most legitimate constructions of reason soon become merely speculative, soon pass, I mean, beyond the sphere of practical application; and the man of affairs, adjusting himself at every turn to the opaque brutality of fact, loses his respect for the higher reaches of logic and forgets that his recognition of facts themselves is an application of logical principles. In his youth, perhaps, he pursued metaphysics, which are the love-affairs of the understanding; now he is wedded to convention and seeks in the passion he calls business or in the habit he calls duty some substitute for natural happiness. He fears to question the value of his life, having found that such questioning adds nothing to his powers; and he thinks the mariner would die of old age in port who should wait for reason to justify his voyage. Reason is indeed like the sad Iphigenia whom her royal father, the Will, must sacrifice before any wind can fill his sails. The emanation of all things from the One involves not only the incarnation but the crucifixion of the Logos. Reason must be eclipsed by its supposed expressions, and can only shine in a darkness which does not comprehend it. For reason is essentially hypothetical and subsidiary, and can never constitute what it expresses in man, nor what it recognises in nature.
If logic should refuse to make this initial self-sacrifice and to subordinate itself to impulse and fact, it would immediately become irrational and forfeit its own justification. For it exists by virtue of a human impulse and in answer to a human need. To ask a man, in the satisfaction of a metaphysical passion, to forego every other good is to render him fanatical and to shut his eyes daily to the sun in order that he may see better by the star-light. The radical fault of rationalism is not any incidental error committed in its deductions, although such necessarily abound in every human system. Its great original sin is its denial of its own basis and its refusal to occupy its due place in the world, an ignorant fear of being invalidated by its history and dishonoured, as it were, if its ancestry is hinted at. Only bastards should fear that fate, and criticism would indeed be fatal to a bastard philosophy, to one that does not spring from practical reason and has no roots in life. But those products of reason which arise by reflection on fact, and those spontaneous and demonstrable systems of ideas which can be verified in experience, and thus serve to render the facts calculable and articulate, will lose nothing of their lustre by discovering their lineage. So the idea of nature remains true after psychology has analysed its origin, and not only true, but beautiful and beneficent. For unlike many negligible products of speculative fancy it is woven out of recurrent perceptions into a hypothetical cause from which further perceptions can be deduced as they are actually experienced.
Such a mechanism once discovered confirms itself at every breath we draw, and surrounds every object in history and nature with infinite and true suggestions, making it doubly interesting, fruitful, and potent over the mind. The naturalist accordingly welcomes criticism because his constructions, though no less hypothetical and speculative than the idealist’s dreams, are such legitimate and fruitful fictions that they are obvious truths. For truth, at the intelligible level where it arises, means not sensible fact, but valid ideation, verified hypothesis, and inevitable, stable inference. If the idealist fears and deprecates any theory of his own origin and function, he is only obeying the instinct of self-preservation; for he knows very well that his past will not bear examination. He is heir to every superstition and by profession an apologist; his deepest vocation is to rescue, by some logical tour de force, what spontaneously he himself would have taken for a consecrated error. Now history and criticism would involve, as he instinctively perceives, the reduction of his doctrines to their pragmatic value, to their ideal significance for real life. But he detests any admission of relativity in his doctrines, all the more because he cannot avow his reasons for detesting it; and zeal, here as in so many cases, becomes the cover and evidence of a bad conscience. Bigotry and craft, with a rhetorical vilification of enemies, then come to reinforce in the prophet that natural limitation of his interests which turns his face away from history and criticism; until his system, in its monstrous unreality and disingenuousness, becomes intolerable, and provokes a general revolt in which too often the truth of it is buried with the error in a common oblivion.
If idealism is intrenched in the very structure of human reason, empiricism represents all those energies of the external universe which, as Spinoza says, must infinitely exceed the energies of man. If meditation breeds science, wisdom comes by disillusion, even on the subject of science itself. Docility to the facts makes the sanity of science. Reason is only half grown and not really distinguishable from imagination so long as she cannot check and recast her own processes wherever they render the moulds of thought unfit for their subject-matter. Docility is, as we have seen, the deepest condition of reason’s existence; for if a form of mental synthesis were by chance developed which was incapable of appropriating the data of sense, these data could not be remembered or introduced at all into a growing and cumulative experience. Sensations would leave no memorial; while logical thoughts would play idly, like so many parasites in the mind, and ultimately languish and die of inanition. To be nourished and employed, intelligence must have developed such structure and habits as will enable it to assimilate what food comes in its way; so that the persistence of any intellectual habit is a proof that it has some applicability, however partial, to the facts of sentience.
This applicability, the prerequisite of significant thought, is also its eventual test; and the gathering of new experiences, the consciousness of more and more facts crowding into the memory and demanding co-ordination, is at once the presentation to reason of her legitimate problem and a proof that she is already at work. It is a presentation of her problem, because reason is not a faculty of dreams but a method in living; and by facing the flux of sensations and impulses that constitute mortal life with the gift of ideal construction and the aspiration toward eternal goods, she is only doing her duty and manifesting what she is. To accumulate facts, moreover, is in itself to prove that rational activity is already awakened, because a consciousness of multitudinous accidents diversifying experience involves a wide scope in memory, good methods of classification, and keen senses, so that all working together they may collect many observations. Memory and all its instruments are embodiments, on a modest scale, of rational activities which in theory and speculation reappear upon a higher level. The expansion of the mind in point of retentiveness and wealth of images is as much an advance in knowledge as is its development in point of organisation. The structure may be widened at the base as well as raised toward its ideal summit, and while a mass of information imperfectly digested leaves something still for intelligence to do, it shows at the same time how much intelligence has done already.
The function of reason is to dominate experience; and obviously openness to new impressions is no less necessary to that end than is the possession of principles by which new impressions may be interpreted.
CHAPTER IX—HOW THOUGHT IS PRACTICAL
Nothing is more natural or more congruous with all the analogies of experience than that animals should feel and think. The relation of mind to body, of reason to nature, seems to be actually this: when bodies have reached a certain complexity and vital equilibrium, a sense begins to inhabit them which is focussed upon the preservation of that body and on its reproduction. This sense, as it becomes reflective and expressive of physical welfare, points more and more to its own persistence and harmony, and generates the Life of Reason. Nature is reason’s basis and theme; reason is nature’s consciousness; and, from the point of view of that consciousness when it has arisen, reason is also nature’s justification and goal.
To separate things so closely bound together as are mind and body, reason and nature, is consequently a violent and artificial divorce, and a man of judgment will instinctively discredit any philosophy in which it is decreed. But to avoid divorce it is well first to avoid unnatural unions, and not to attribute to our two elements, which must be partners for life, relations repugnant to their respective natures and offices. Now the body is an instrument, the mind its function, the witness and reward of its operation. Mind is the body’s entelechy, a value which accrues to the body when it has reached a certain perfection, of which it would be a pity, so to speak, that it should remain unconscious; so that while the body feeds the mind the mind perfects the body, lifting it and all its natural relations and impulses into the moral world, into the sphere of interests and ideas.
No connection could be closer than this reciprocal involution, as nature and life reveal it; but the connection is natural, not dialectical. The union will be denaturalised and, so far as philosophy goes, actually destroyed, if we seek to carry it on into logical equivalence. If we isolate the terms mind and body and study the inward implications of each apart, we shall never discover the other. That matter cannot, by transposition of its particles, become what we call consciousness, is an admitted truth; that mind cannot become its own occasions or determine its own march, though it be a truth not recognised by all philosophers, is in itself no less obvious. Matter, dialectically studied, makes consciousness seem a superfluous and unaccountable addendum; mind, studied in the same way, makes nature an embarrassing idea, a figment which ought to be subservient to conscious aims and perfectly transparent, but which remains opaque and overwhelming. In order to escape these sophistications, it suffices to revert to immediate observation and state the question in its proper terms: nature lives, and perception is a private echo and response to ambient motions. The soul is the voice of the body’s interests; in watching them a man defines the world that sustains him and that conditions all his satisfactions. In discerning his origin he christens Nature by the eloquent name of mother, under which title she enters the universe of discourse. Simultaneously he discerns his own existence and marks off the inner region of his dreams. And it behooves him not to obliterate these discoveries. By trying to give his mind false points of attachment in nature he would disfigure not only nature but also that reason which is so much the essence of his life.
Consciousness, then, is the expression of bodily life and the seat of all its values. Its place in the natural world is like that of its own ideal products, art, religion, or science; it translates natural relations into synthetic and ideal symbols by which things are interpreted with reference to the interests of consciousness itself. This representation is also an existence and has its place along with all other existences in the bosom of nature. In this sense its connection with its organs, and with all that affects the body or that the body affects, is a natural connection. If the word cause did not suggest dialectical bonds we might innocently say that thought was a link in the chain of natural causes. It is at least a link in the chain of natural events; for it has determinate antecedents in the brain and senses and determinate consequents in actions and words. But this dependence and this efficacy have nothing logical about them; they are habitual collocations in the world, like lightning and thunder. A more minute inspection of psycho-physical processes, were it practicable, would doubtless disclose undreamed of complexities and harmonies in them; the mathematical and dynamic relations of stimulus and sensation might perhaps be formulated with precision. But the terms used in the equation, their quality and inward habit, would always remain data which the naturalist would have to assume after having learned them by inspection. Movement could never be deduced dialectically or graphically from thought nor thought from movement. Indeed no natural relation is in a different case. Neither gravity, nor chemical reaction, nor life and reproduction, nor time, space, and motion themselves are logically deducible, nor intelligible in terms of their limits. The phenomena have to be accepted at their face value and allowed to retain a certain empirical complexity; otherwise the seed of all science is sterilised and calculation cannot proceed for want of discernible and pregnant elements.
How fine nature’s habits may be, where repetition begins, and down to what depth a mathematical treatment can penetrate, is a question for the natural sciences to solve. Whether consciousness, for instance, accompanies vegetative life, or even all motion, is a point to be decided solely by empirical analogy. When the exact physical conditions of thought are discovered in man, we may infer how far thought is diffused through the universe, for it will be coextensive with the conditions it will have been shown to have. Now, in a very rough way, we know already what these conditions are. They are first the existence of an organic body and then its possession of adaptable instincts, of instincts that can be modified by experience. This capacity is what an observer calls intelligence; docility is the observable half of reason. When an animal winces at a blow and readjusts his pose, we say he feels; and we say he thinks when we see him brooding over his impressions, and find him launching into a new course of action after a silent decoction of his potential impulses. Conversely, when observation covers both the mental and the physical process, that is, in our own experience, we find that felt impulses, the conceived objects for which they make, and the values they determine are all correlated with animal instincts and external impressions. A desire is the inward sign of a physical proclivity to act, an image in sense is the sign in most cases of some material object in the environment and always, we may presume, of some cerebral change. The brain seems to simmer like a caldron in which all sorts of matters are perpetually transforming themselves into all sorts of shapes. When this cerebral reorganisation is pertinent to the external situation and renders the man, when he resumes action, more a master of his world, the accompanying thought is said to be practical; for it brings a consciousness of power and an earnest of success.
Cerebral processes are of course largely hypothetical. Theory suggests their existence, and experience can verify that theory only in an indirect and imperfect manner. The addition of a physical substratum to all thinking is only a scientific expedient, a hypothesis expressing the faith that nature is mechanically intelligible even beyond the reaches of minute verification. The accompanying consciousness, on the other hand, is something intimately felt by each man in his own person; it is a portion of crude and immediate experience. That it accompanies changes in his body and in the world is not an inference for him but a datum. But when crude experience is somewhat refined and the soul, at first mingled with every image, finds that it inhabits only her private body, to whose fortunes hers are altogether wedded, we begin to imagine that we know the cosmos at large better than the spirit; for beyond the narrow limits of our own person only the material phase of things is open to our observation. To add a mental phase to every part and motion of the cosmos is then seen to be an audacious fancy. It violates all empirical analogy, for the phenomenon which feeling accompanies in crude experience is not mere material existence, but reactive organisation and docility.
