Science, "reason" is not therefore something laid from above upon experience. Suggested and tested in experience, it is also employed through inventions in a thousand ways to expand and enrich experience.

Although, as has been so often repeated, this self-creation and self-regulation of experience is still largely technological rather than truly artistic or human, yet what has been achieved contains the guaranty of the possibility of an intelligent administering of experience. The limits are moral and intellectual, due to defects in our good will and knowledge. They are not inherent metaphysically in the very nature of experience. "Reason" as a faculty separate from experience, introducing us to a superior region of universal truths begins now to strike us as remote, uninteresting and unimportant.

Reason, as a Kantian faculty that introduces generality and regularity into experience, strikes us more and more as superfluous--the unnecessary creation of men addicted to traditional formalism and to elaborate terminology. Concrete suggestions arising from past experiences, developed and matured in the light of the needs and deficiencies of the present, employed as aims and methods of specific reconstruction, and tested by success or failure in accomplishing this task of readjustment, suffice. To such empirical suggestions used in constructive fashion for new ends the name intelligence is given.

This recognition of the place of active and planning thought within the very processes of experience radically alters the traditional status of the technical problems of particular and universal, sense and reason, perceptual and conceptual. But the alteration is of much more than technical significance. For reason is experimental intelligence, conceived after the pattern of science, and used in the creation of social arts; it has something to do. It liberates man from the bondage of the past, due to ignorance and accident hardened into custom. It projects a better future and a.s.sists man in its realization. And its operation is always subject to test in experience. The plans which are formed, the principles which man projects as guides of reconstructive action, are not dogmas. They are hypotheses to be worked out in practice, and to be rejected, corrected and expanded as they fail or succeed in giving our present experience the guidance it requires. We may call them programmes of action, but since they are to be used in making our future acts less blind, more directed, they are flexible.

Intelligence is not something possessed once for all. It is in constant process of forming, and its retention requires constant alertness in observing consequences, an open-minded will to learn and courage in re-adjustment.

In contrast with this experimental and re-adjusting intelligence, it must be said that Reason as employed by historic rationalism has tended to carelessness, conceit, irresponsibility, and rigidity--in short absolutism. A certain school of contemporary psychology uses the term "rationalization" to denote those mental mechanisms by which we unconsciously put a better face on our conduct or experience than facts justify. We excuse ourselves to ourselves by introducing a purpose and order into that of which we are secretly ashamed. In like fashion, historic rationalism has often tended to use Reason as an agency of justification and apologetics. It has taught that the defects and evils of actual experience disappear in the "rational whole" of things; that things _appear_ evil merely because of the partial, incomplete nature of experience. Or, as was noted by Bacon, "reason" a.s.sumes a false simplicity, uniformity and universality, and opens for science a path of fict.i.tious ease. This course results in intellectual irresponsibility and neglect:--irresponsibility because rationalism a.s.sumes that the concepts of reason are so self-sufficient and so far above experience that they need and can secure no confirmation in experience. Neglect, because this same a.s.sumption makes men careless about concrete observations and experiments. Contempt for experience has had a tragic revenge _in_ experience; it has cultivated disregard for fact and this disregard has been paid for in failure, sorrow and war.

The dogmatic rigidity of Rationalism is best seen in the consequences of Kant's attempt to b.u.t.tress an otherwise chaotic experience with pure concepts. He set out with a laudable attempt at restricting the extravagant pretensions of Reason apart from experience. He called his philosophy critical. But because he taught that the understanding employs fixed, _a priori_, concepts, in order to introduce connection into experience and thereby make known _objects_ possible (stable, regular relationships of qualities), he developed in German thought a curious contempt for the living variety of experience and a curious overestimate of the value of system, order, regularity for their own sakes. More practical causes were at work in producing the peculiarly German regard for drill, discipline, "order" and docility.

But Kant's philosophy served to provide an intellectual justification or "rationalization" of subordination of individuals to fixed and ready-made universal, "principles," laws. Reason and law were held to be synonyms. And as reason came into experience from without and above, so law had to come into life from some external and superior authority.

The practical correlate to absolutism is rigidity, stiffness, inflexibility of disposition. When Kant taught that some conceptions, and these the important ones, are _a priori_, that they do not arise in experience and cannot be verified or tested in experience, that without such ready-made injections into experience the latter is anarchic and chaotic, he fostered the spirit of absolutism, even though technically he denied the possibility of absolutes. His successors were true to his spirit rather than his letter, and so they taught absolutism systematically. That the Germans with all their scientific competency and technological proficiency should have fallen into their tragically rigid and "superior" style of thought and action (tragic because involving them in inability to understand the world in which they lived) is a sufficient lesson of what may be involved in a systematical denial of the experimental character of intelligence and its conceptions.

By common consent, the effect of English empiricism was sceptical where that of German rationalism was apologetic; it undermined where the latter justified. It detected accidental a.s.sociations formed into customs under the influence of self- or cla.s.s-interest where German rational-idealism discovered profound meanings due to the necessary evolution of absolute reason. The modern world has suffered because in so many matters philosophy has offered it only an arbitrary choice between hard and fast opposities: Disintegrating a.n.a.lysis _or_ rigid synthesis; complete radicalism neglecting and attacking the historic past as trivial and harmful, _or_ complete conservatism idealizing inst.i.tutions as embodiments of eternal reason; a resolution of experience into atomic elements that afford no support to stable organization _or_ a clamping down of all experience by fixed categories and necessary concepts--these are the alternatives that conflicting schools have presented.

They are the logical consequences of the traditional opposition of Sense and Thought, Experience and Reason. Common sense has refused to follow both theories to their ultimate logic, and has fallen back on faith, intuition or the exigencies of practical compromise. But common sense too often has been confused and hampered instead of enlightened and directed by the philosophies proffered it by professional intellectuals.

Men who are thrown back upon "common sense" when they appeal to philosophy for some general guidance are likely to fall back on routine, the force of some personality, strong leadership or on the pressure of momentary circ.u.mstances. It would be difficult to estimate the harm that has resulted because the liberal and progressive movement of the eighteenth and earlier nineteenth centuries had no method of intellectual articulation commensurate with its practical aspirations.

Its heart was in the right place. It was humane and social in intention. But it had no theoretical instrumentalities of constructive power. Its head was sadly deficient. Too often the logical import of its professed doctrines was almost anti-social in their atomistic individualism, anti-human in devotion to brute sensation. This deficiency played into the hands of the reactionary and obscurantist.

The strong point of the appeal to fixed principles transcending experience, to dogmas incapable of experimental verification, the strong point of reliance upon _a priori_ canons of truth and standards of morals in opposition to dependence upon fruits and consequences in experience, has been the unimaginative conception of experience which professed philosophic empiricists have entertained and taught.

A philosophic reconstruction which should relieve men of having to choose between an impoverished and truncated experience on one hand and an artificial and impotent reason on the other would relieve human effort from the heaviest intellectual burden it has to carry. It would destroy the division of men of good will into two hostile camps. It would permit the co-operation of those who respect the past and the inst.i.tutionally established with those who are interested in establishing a freer and happier future. For it would determine the conditions under which the funded experience of the past and the contriving intelligence which looks to the future can effectually interact with each other. It would enable men to glorify the claims of reason without at the same time falling into a paralyzing worship of super-empirical authority or into an offensive "rationalization" of things as they are.

CHAPTER V

CHANGED CONCEPTIONS OF THE IDEAL AND THE REAL

It has been noted that human experience is made human through the existence of a.s.sociations and recollections, which are strained through the mesh of imagination so as to suit the demands of the emotions. A life that is humanly interesting is, short of the results of discipline, a life in which the tedium of vacant leisure is filled with images that excite and satisfy. It is in this sense that poetry preceded prose in human experience, religion antedated science, and ornamental and decorative art while it could not take the place of utility early reached a development out of proportion to the practical arts. In order to give contentment and delight, in order to feed present emotion and give the stream of conscious life intensity and color, the suggestions which spring from past experiences are worked over so as to smooth out their unpleasantnesses and enhance their enjoyableness. Some psychologists claim that there is what they call a natural tendency to obliviscence of the disagreeable--that men turn from the unpleasant in thought and recollection as they do from the obnoxious in action. Every serious-minded person knows that a large part of the effort required in moral discipline consists in the courage needed to acknowledge the unpleasant consequences of one's past and present acts. We squirm, dodge, evade, disguise, cover up, find excuses and palliations--anything to render the mental scene less uncongenial. In short, the tendency of spontaneous suggestion is to idealize experience, to give it in consciousness qualities which it does not have in actuality. Time and memory are true artists; they remould reality nearer to the heart's desire.

As imagination becomes freer and less controlled by concrete actualities, the idealizing tendency takes further flights unrestrained by the rein of the prosaic world. The things most emphasized in imagination as it reshapes experience are things which are absent in reality. In the degree in which life is placid and easy, imagination is sluggish and bovine. In the degree in which life is uneasy and troubled, fancy is stirred to frame pictures of a contrary state of things. By reading the characteristic features of any man's castles in the air you can make a shrewd guess as to his underlying desires which are frustrated. What is difficulty and disappointment in real life becomes conspicuous achievement and triumph in revery; what is negative in fact will be positive in the image drawn by fancy; what is vexation in conduct will be compensated for in high relief in idealizing imagination.

These considerations apply beyond mere personal psychology. They are decisive for one of the most marked traits of cla.s.sic philosophy:--its conception of an ultimate supreme Reality which is essentially ideal in nature. Historians have more than once drawn an instructive parallel between the developed Olympian Pantheon of Greek religion and the Ideal Realm of Platonic philosophy. The G.o.ds, whatever their origin and original traits, became idealized projections of the selected and matured achievements which the Greeks admired among their mortal selves.

The G.o.ds were like mortals, but mortals living only the lives which men would wish to live, with power intensified, beauty perfected, and wisdom ripened. When Aristotle criticized the theory of Ideas of his master, Plato, by saying that the Ideas were after all only things of sense eternalized, he pointed out in effect the parallelism of philosophy with religion and art to which allusion has just been made. And save for matters of merely technical import, is it not possible to say of Aristotle's Forms just what he said of Plato's Ideas? What are they, these Forms and Essences which so profoundly influenced for centuries the course of science and theology, save the objects of ordinary experience with their blemishes removed, their imperfections eliminated, their lacks rounded out, their suggestions and hints fulfilled? What are they in short but the objects of familiar life divinized because reshaped by the idealizing imagination to meet the demands of desire in just those respects in which actual experience is disappointing?

That Plato, and Aristotle in somewhat different fashion, and Plotinus and Marcus Aurelius and Saint Thomas Aquinas, and Spinoza and Hegel all taught that Ultimate Reality is either perfectly Ideal and Rational in nature, or else has absolute ideality and rationality as its necessary attribute, are facts well known to the student of philosophy. They need no exposition here. But it is worth pointing out that these great systematic philosophies defined perfect Ideality in conceptions that express the opposite of those things which make life unsatisfactory and troublesome. What is the chief source of the complaint of poet and moralist with the goods, the values and satisfactions of experience?

Rarely is the complaint that such things do not exist; it is that although existing they are momentary, transient, fleeting. They do not stay; at worst they come only to annoy and tease with their hurried and disappearing taste of what might be; at best they come only to inspire and instruct with a pa.s.sing hint of truer reality. This commonplace of the poet and moralist as to the impermanence not only of sensuous enjoyment, but of fame and civic achievements was profoundly reflected upon by philosophers, especially by Plato and Aristotle. The results of their thinking have been wrought into the very fabric of western ideas.

Time, change, movement are signs that what the Greeks called Non-Being somehow infect true Being. The phraseology is now strange, but many a modern who ridicules the conception of Non-Being repeats the same thought under the name of the Finite or Imperfect.

Wherever there is change, there is instability, and instability is proof of something the matter, of absence, deficiency, incompleteness. These are the ideas common to the connection between change, becoming and perishing, and Non-Being, finitude and imperfection. Hence complete and true Reality must be changeless, unalterable, so full of Being that it always and forever maintains itself in fixed rest and repose. As Bradley, the most dialectially ingenious Absolutist of our own day, expresses the doctrine "Nothing that is perfectly real moves." And while Plato took, comparatively speaking, a pessimistic view of change as mere lapse and Aristotle a complacent view of it as tendency to realization, yet Aristotle doubted no more than Plato that the fully realized reality, the divine and ultimate, is changeless. Though it is called Activity or Energy, the Activity knew no change, the energy did nothing.

It was the activity of an army forever marking time and never going anywhere.

From this contrast of the permanent with the transient arise other features which mark off the Ultimate Reality from the imperfect realities of practical life. Where there is change, there is of necessity numerical plurality, multiplicity, and from variety comes opposition, strife. Change is alteration, or "othering" and this means diversity. Diversity means division, and division means two sides and their conflict. The world which is transient _must_ be a world of discord, for in lacking stability it lacks the government of unity. Did unity completely rule, these would remain an unchanging totality. What alters has parts and partialities which, not recognizing the rule of unity, a.s.sert themselves independently and make life a scene of contention and discord. Ultimate and true Being on the other hand, since it is changeless is Total, All-Comprehensive and One. Since it is One, it knows only harmony, and therefore enjoys complete and eternal Good.

It _is_ Perfection.

Degrees of knowledge and truth correspond with degrees of reality point by point. The higher and more complete the Reality the truer and more important the knowledge that refers to it. Since the world of becoming, of origins and perishings, is deficient in true Being, it cannot be known in the best sense. To know it means to neglect its flux and alteration and discover some permanent form which limits the processes that alter in time. The acorn undergoes a series of changes; these are knowable only in reference to the fixed form of the oak which is the same in the entire oak species in spite of the numerical diversity of trees. Moreover, this form limits the flux of growth at both ends, the acorn coming from the oak as well as pa.s.sing into it. Where such unifying and limiting eternal forms cannot be detected, there is mere aimless variation and fluctuation, and knowledge is out of the question.

On the other hand, as objects are approached in which there is no movement at all, knowledge becomes really demonstrative, certain, perfect--truth pure and unalloyed. The heavens can be more truly known than the earth, G.o.d the unmoved mover than the heavens.

From this fact follows the superiority of contemplative to practical knowledge, of pure theoretical speculation to experimentation, and to any kind of knowing that depends upon changes in things or that induces change in them. Pure knowing is pure beholding, viewing, noting. It is complete in itself. It looks for nothing beyond itself; it lacks nothing and hence has no aim or purpose. It is most emphatically its own excuse for being. Indeed, pure contemplative knowing is so much the most truly self-enclosed and self-sufficient thing in the universe that it is the highest and indeed the only attribute that can be ascribed to G.o.d, the Highest Being in the scale of Being. Man himself is divine in the rare moments when he attains to purely self-sufficient theoretical insight.

In contrast with such knowing, the so-called knowing of the artisan is base. He has to bring about changes in things, in wood and stone, and this fact is of itself evidence that his material is deficient in Being.

What condemns his knowledge even more is the fact that it is not disinterestedly for its own sake. It has reference to results to be attained, food, clothing, shelter, etc. It is concerned with things that perish, the body and its needs. It thus has an ulterior aim, and one which itself testifies to imperfection. For want, desire, affection of every sort, indicate lack. Where there is need and desire--as in the case of all practical knowledge and activity--there is incompleteness and insufficiency. While civic or political and moral knowledge rank higher than do the conceptions of the artisan, yet intrinsically considered they are a low and untrue type. Moral and political action is practical; that is, it implies needs and effort to satisfy them. It has an end beyond itself. Moreover, the very fact of a.s.sociation shows lack of self-sufficiency; it shows dependence upon others. Pure knowing is alone solitary, and capable of being carried on in complete, self-sufficing independence.

In short, the measure of the worth of knowledge according to Aristotle, whose views are here summarized, is the degree in which it is purely contemplative. The highest degree is attained in knowing ultimate Ideal Being, pure Mind. This is Ideal, the Form of Forms, because it has no lacks, no needs, and experiences no change or variety. It has no desires because in it all desires are consummated. Since it is perfect Being, it is perfect Mind and perfect Bliss;--the acme of rationality and ideality. One point more and the argument is completed. The kind of knowing that concerns itself with this ultimate reality (which is also ultimate ideality) is philosophy. Philosophy is therefore the last and highest term in pure contemplation. Whatever may be said for any other kind of knowledge, philosophy is self-enclosed. It has nothing to do beyond itself; it has no aim or purpose or function--except to be philosophy--that is, pure, self-sufficing beholding of ultimate reality.

There is of course such a thing as philosophic _study_ which falls short of this perfection. Where there is learning, there is change and becoming. But the function of study and learning of philosophy is, as Plato put it, to convert the eye of the soul from dwelling contentedly upon the images of things, upon the inferior realities that are born and that decay, and to lead it to the intuition of supernal and eternal Being. Thus the mind of the knower is transformed. It becomes a.s.similated to what it knows.

Through a variety of channels, especially Neo-Platonism and St.

Augustine, these ideas found their way into Christian theology; and great scholastic thinkers taught that the end of man is to know True Being, that knowledge is contemplative, that True Being is pure Immaterial Mind, and to know it is Bliss and Salvation. While this knowledge cannot be achieved in this stage of life nor without supernatural aid, yet so far as it is accomplished it a.s.similates the human mind to the divine essence and so const.i.tutes salvation. Through this taking over of the conception of knowledge as Contemplative into the dominant religion of Europe, mult.i.tudes were affected who were totally innocent of theoretical philosophy. There was bequeathed to generations of thinkers as an unquestioned axiom the idea that knowledge is intrinsically a mere beholding or viewing of reality--the spectator conception of knowledge. So deeply engrained was this idea that it prevailed for centuries after the actual progress of science had demonstrated that knowledge is power to transform the world, and centuries after the practice of effective knowledge had adopted the method of experimentation.

Let us turn abruptly from this conception of the measure of true knowledge and the nature of true philosophy to the existing practice of knowledge. Nowadays if a man, say a physicist or chemist, wants to know something, the last thing he does is merely to contemplate. He does not look in however earnest and prolonged way upon the object expecting that thereby he will detect its fixed and characteristic form. He does not expect any amount of such aloof scrutiny to reveal to him any secrets. He proceeds to _do_ something, to bring some energy to bear upon the substance to see how it reacts; he places it under unusual conditions in order to induce some change. While the astronomer cannot change the remote stars, even he no longer merely gazes. If he cannot change the stars themselves, he can at least by lens and prism change their light as it reaches the earth; he can lay traps for discovering changes which would otherwise escape notice. Instead of taking an antagonistic att.i.tude toward change and denying it to the stars because of their divinity and perfection, he is on constant and alert watch to find some change through which he can form an inference as to the formation of stars and systems of stars.

Change in short is no longer looked upon as a fall from grace, as a lapse from reality or a sign of imperfection of Being. Modern science no longer tries to find some fixed form or essence behind each process of change. Rather, the experimental method tries to break down apparent fixities and to induce changes. The form that remains unchanged to sense, the form of seed or tree, is regarded not as the key to knowledge of the thing, but as a wall, an obstruction to be broken down.

Consequently the scientific man experiments with this and that agency applied to this and that condition until something begins to happen; until there is, as we say, something doing. He a.s.sumes that there is change going on all the time, that there is movement within each thing in seeming repose; and that since the process is veiled from perception the way to know it is to bring the thing into novel circ.u.mstances until change becomes evident. In short, the thing which is to be accepted and paid heed to is not what is originally given but that which emerges after the thing has been set under a great variety of circ.u.mstances in order to see how it behaves.

Now this marks a much more general change in the human att.i.tude than perhaps appears at first sight. It signifies nothing less than that the world or any part of it as it presents itself at a given time is accepted or acquiesced in only as _material_ for change. It is accepted precisely as the carpenter, say, accepts things as he finds them. If he took them as things to be observed and noted for their own sake, he never would be a carpenter. He would observe, describe, record the structures, forms and changes which things exhibit to him, and leave the matter there. If perchance some of the changes going on should present him with a shelter, so much the better. But what makes the carpenter a _builder_ is the fact that he notes things not just as objects in themselves, but with reference to what he wants to do to them and with them; to the end he has in mind. Fitness to effect certain special changes that he wishes to see accomplished is what concerns him in the wood and stones and iron which he observes. His attention is directed to the changes they undergo and the changes they make other things undergo so that he may select that combination of changes which will yield him his desired result. It is only by these processes of active manipulation of things in order to realize his purpose that he discovers what the properties of things are. If he foregoes his own purpose and in the name of a meek and humble subscription to things as they "really are" refuses to bend things as they "are" to his own purpose, he not only never achieves his purpose but he never learns what the things themselves are.

They _are_ what they can do and what can be done with them,--things that can be found by deliberate trying.

The outcome of this idea of the right way to know is a profound modification in man's att.i.tude toward the natural world. Under differing social conditions, the older or cla.s.sic conception sometimes bred resignation and submission; sometimes contempt and desire to escape; sometimes, notably in the case of the Greeks, a keen esthetic curiosity which showed itself in acute noting of all the traits of given objects.

In fact, the whole conception of knowledge as beholding and noting is fundamentally an idea connected with esthetic enjoyment and appreciation where the environment is beautiful and life is serene, and with esthetic repulsion and depreciation where life is troubled, nature morose and hard. But in the degree in which the active conception of knowledge prevails, and the environment is regarded as something that has to be changed in order to be truly known, men are imbued with courage, with what may almost be termed an aggressive att.i.tude toward nature. The latter becomes plastic, something to be subjected to human uses. The moral disposition toward change is deeply modified. This loses its pathos, it ceases to be haunted with melancholy through suggesting only decay and loss. Change becomes significant of new possibilities and ends to be attained; it becomes prophetic of a better future. Change is a.s.sociated with progress rather than with lapse and fall. Since changes are going on anyway, the great thing is to learn enough about them so that we be able to lay hold of them and turn them in the direction of our desires. Conditions and events are neither to be fled from nor pa.s.sively acquiesced in; they are to be utilized and directed. They are either obstacles to our ends or else means for their accomplishment. In a profound sense knowing ceases to be contemplative and becomes practical.

Unfortunately men, educated men, cultivated men in particular, are still so dominated by the older conception of an aloof and self-sufficing reason and knowledge that they refuse to perceive the import of this doctrine. They think they are sustaining the cause of impartial, thorough-going and disinterested reflection when they maintain the traditional philosophy of intellectualism--that is, of knowing as something self-sufficing and self-enclosed. But in truth, historic intellectualism, the spectator view of knowledge, is a purely compensatory doctrine which men of an intellectual turn have built up to console themselves for the actual and social impotency of the calling of thought to which they are devoted. Forbidden by conditions and held back by lack of courage from making their knowledge a factor in the determination of the course of events, they have sought a refuge of complacency in the notion that knowing is something too sublime to be contaminated by contact with things of change and practice. They have transformed knowing into a morally irresponsible estheticism. The true import of the doctrine of the operative or practical character of knowing, of intelligence, is objective. It means that the structures and objects which science and philosophy set up in contrast to the things and events of concrete daily experience do not const.i.tute a realm apart in which rational contemplation may rest satisfied; it means that they represent the selected obstacles, material means and ideal methods of giving direction to that change which is bound to occur anyway.

This change of human disposition toward the world does not mean that man ceases to have ideals, or ceases to be primarily a creature of the imagination. But it does signify a radical change in the character and function of the ideal realm which man shapes for himself. In the cla.s.sic philosophy, the ideal world is essentially a haven in which man finds rest from the storms of life; it is an asylum in which he takes refuge from the troubles of existence with the calm a.s.surance that it alone is supremely real. When the belief that knowledge is active and operative takes hold of men, the ideal realm is no longer something aloof and separate; it is rather that collection of imagined possibilities that stimulates men to new efforts and realizations. It still remains true that the troubles which men undergo are the forces that lead them to project pictures of a better state of things. But the picture of the better is shaped so that it may become an instrumentality of action, while in the cla.s.sic view the Idea belongs ready-made in a noumenal world. Hence, it is only an object of personal aspiration or consolation, while to the modern, an idea is a suggestion of something to be done or of a way of doing.

An ill.u.s.tration will, perhaps, make the difference clear. Distance is an obstacle, a source of trouble. It separates friends and prevents intercourse. It isolates, and makes contact and mutual understanding difficult. This state of affairs provokes discontent and restlessness; it excites the imagination to construct pictures of a state of things where human intercourse is not injuriously affected by s.p.a.ce. Now there are two ways out. One way is to pa.s.s from a mere dream of some heavenly realm in which distance is abolished and by some magic all friends are in perpetual transparent communication, to pa.s.s, I say, from some idle castle-building to philosophic reflection. s.p.a.ce, distance, it will then be argued, is merely phenomenal; or, in a more modern version, subjective. It is not, metaphysically speaking, real. Hence the obstruction and trouble it gives is not after all "real" in the metaphysical sense of reality. Pure minds, pure spirits, do not live in a s.p.a.ce world; for them distance is not. Their relationships in the true world are not in any way affected by special considerations. Their intercommunication is direct, fluent, un.o.bstructed.

Does the ill.u.s.tration involve a caricature of ways of philosophizing with which we are all familiar? But if it is not an absurd caricature, does it not suggest that much of what philosophies have taught about the ideal and noumenal or superiorly real world, is after all, only casting a dream into an elaborate dialectic form through the use of a speciously scientific terminology? Practically, the difficulty, the trouble, remains. Practically, however it may be "metaphysically," s.p.a.ce is still real:--it acts in a definite objectionable way. Again, man dreams of some better state of things. From troublesome fact he takes refuge in fantasy. But this time, the refuge does not remain a permanent and remote asylum.

The idea becomes a standpoint from which to examine existing occurrences and to see if there is not among them something which gives a hint of how communication at a distance can be effected, something to be utilized as a medium of speech at long range. The suggestion or fancy though still ideal is treated as a possibility capable of realization _in_ the concrete natural world, not as a superior reality apart from that world. As such, it becomes a platform from which to scrutinize natural events. Observed from the point of view of this possibility, things disclose properties. .h.i.therto undetected. In the light of these ascertainments, the idea of some agency for speech at a distance becomes less vague and floating: it takes on positive form. This action and reaction goes on. The possibility or idea is employed as a method for observing actual existence; and in the light of what is discovered the possibility takes on concrete existence. It becomes less of a mere idea, a fancy, a wished-for possibility, and more of an actual fact. Invention proceeds, and at last we have the telegraph, the telephone, first through wires, and then with no artificial medium. The concrete environment is transformed in the desired direction; it is idealized in fact and not merely in fancy. The ideal is realized through its own use as a tool or method of inspection, experimentation, selection and combination of concrete natural operations.

Let us pause to take stock of results. The division of the world into two kinds of Being, one superior, accessible only to reason and ideal in nature, the other inferior, material, changeable, empirical, accessible to sense-observation, turns inevitably into the idea that knowledge is contemplative in nature. It a.s.sumes a contrast between theory and practice which was all to the disadvantage of the latter. But in the actual course of the development of science, a tremendous change has come about. When the practice of knowledge ceased to be dialectical and became experimental, knowing became preoccupied with changes and the test of knowledge became the ability to bring about certain changes.

Knowing, for the experimental sciences, means a certain kind of intelligently conducted doing; it ceases to be contemplative and becomes in a true sense practical. Now this implies that philosophy, unless it is to undergo a complete break with the authorized spirit of science, must also alter its nature. It must a.s.sume a practical nature; it must become operative and experimental. And we have pointed out what an enormous change this transformation of philosophy entails in the two conceptions which have played the greatest role in historic philosophizing--the conceptions of the "real" and "ideal" respectively.

The former ceases to be something ready-made and final; it becomes that which has to be accepted as the material of change, as the obstructions and the means of certain specific desired changes. The ideal and rational also ceased to be a separate ready-made world incapable of being used as a lever to transform the actual empirical world, a mere asylum from empirical deficiencies. They represent intelligently thought-out possibilities _of_ the existent world which may be used as methods for making over and improving it.

Philosophically speaking, this is the great difference involved in the change from knowledge and philosophy as contemplative to operative. The change does not mean the lowering in dignity of philosophy from a lofty plane to one of gross utilitarianism. It signifies that the prime function of philosophy is that of rationalizing the _possibilities_ of experience, especially collective human experience. The scope of this change may be realized by considering how far we are from accomplishing it. In spite of inventions which enable men to use the energies of nature for their purposes, we are still far from habitually treating knowledge as the method of active control of nature and of experience.

We tend to think of it after the model of a spectator viewing a finished picture rather than after that of the artist producing the painting.

Thus there arise all the questions of epistemology with which the technical student of philosophy is so familiar, and which have made modern philosophy in especial so remote from the understanding of the everyday person and from the results and processes of science. For these questions all spring from the a.s.sumption of a merely beholding mind on one side and a foreign and remote object to be viewed and noted on the other. They ask how a mind and world, subject and object, so separate and independent can by any possibility come into such relationship to each other as to make true knowledge possible. If knowing were habitually conceived of as active and operative, after the a.n.a.logy of experiment guided by hypothesis, or of invention guided by the imagination of some possibility, it is not too much to say that the first effect would be to emanc.i.p.ate philosophy from all the epistemological puzzles which now perplex it. For these all arise from a conception of the relation of mind and world, subject and object, in knowing, which a.s.sumes that to know is to seize upon what is already in existence.

Modern philosophic thought has been so preoccupied with these puzzles of epistemology and the disputes between realist and idealist, between phenomenalist and absolutist, that many students are at a loss to know what would be left for philosophy if there were removed both the metaphysical task of distinguishing between the noumenal and phenomenal worlds and the epistemological task of telling how a separate subject can know an independent object. But would not the elimination of these traditional problems permit philosophy to devote itself to a more fruitful and more needed task? Would it not encourage philosophy to face the great social and moral defects and troubles from which humanity suffers, to concentrate its attention upon clearing up the causes and exact nature of these evils and upon developing a clear idea of better social possibilities; in short upon projecting an idea or ideal which, instead of expressing the notion of another world or some far-away unrealizable goal, would be used as a method of understanding and rectifying specific social ills?

This is a vague statement. But note in the first place that such a conception of the proper province of philosophy where it is released from vain metaphysics and idle epistemology is in line with the origin of philosophy sketched in the first hour. And in the second place, note how contemporary society, the world over, is in need of more general and fundamental enlightenment and guidance than it now possesses. I have tried to show that a radical change of the conception of knowledge from contemplative to active is the inevitable result of the way in which inquiry and invention are now conducted. But in claiming this, it must also be conceded, or rather a.s.serted, that so far the change has influenced for the most part only the more technical side of human life.

The sciences have created new industrial arts. Man's physical command of natural energies has been indefinitely multiplied. There is control of the sources of material wealth and prosperity. What would once have been miracles are now daily performed with steam and coal and electricity and air, and with the human body. But there are few persons optimistic enough to declare that any similar command of the forces which control man's social and moral welfare has been achieved.

Where is the moral progress that corresponds to our economic accomplishments? The latter is the direct fruit of the revolution that has been wrought in physical science. But where is there a corresponding human science and art? Not only has the improvement in the method of knowing remained so far mainly limited to technical and economic matters, but this progress has brought with it serious new moral disturbances. I need only cite the late war, the problem of capital and labor, the relation of economic cla.s.ses, the fact that while the new science has achieved wonders in medicine and surgery, it has also produced and spread occasions for diseases and weaknesses. These considerations indicate to us how undeveloped are our politics, how crude and primitive our education, how pa.s.sive and inert our morals.

The causes remain which brought philosophy into existence as an attempt to find an intelligent subst.i.tute for blind custom and blind impulse as guides to life and conduct. The attempt has not been successfully accomplished. Is there not reason for believing that the release of philosophy from its burden of sterile metaphysics and sterile epistemology instead of depriving philosophy of problems and subject-matter would open a way to questions of the most perplexing and the most significant sort?
