Essays in Experimental Logic Part 2

But not one of these processes is "subjective" in any sense which puts subjectivity in opposition to the public out-of-doors world of nature and human companions.h.i.+p. To set genesis in opposition to a.n.a.lysis is merely to overlook the fact that the sciences of existence have found that considerations of genesis afford their most effective methods of a.n.a.lysis.[10]

The same kind of consideration applies to the favorable view taken of psychology. If reference to modes and ways of experience--to experiencing--is important for understanding the things with which philosophy deals, then psychology is useful as a matter of course. For what is meant by psychology is precisely a discrimination of the acts and att.i.tudes of the organism which have a bearing upon respective subject-matters and which have accordingly to be taken account of before the subject-matters can be properly discriminated.

The matter was especially striking in the case of Lotze. He protested constantly against the use of psychology, and yet his own data and procedures were infected at every turn by psychology, and, if I am at all correct, by a false psychology. The particular separation which he made between psychology and logic rested indeed upon a particular psychological a.s.sumption. The question is worth asking: Is not the marked aversion on the part of some philosophers to any reference to psychology a Freudian symptom?

A word more upon the place a.s.signed by the essays to _need_ and _purpose_ and the humanistic factor generally. To save time I may quote a sentence from an early review which attributes to the essays the following doctrine: "If the plan turns out to be useful for our need, it is correct--the judgment is true. The real-ideal distinction is that between stimulus of environment and plan of action or tentative response. Both real and ideal are equally experiences of the individual man." These words can be interpreted either so as to convey the position fairly, or so as radically to misconceive it; the latter course is a little easier, as the words stand. That "real and ideal"

are experiences of the individual man in the sense that they actually present themselves as specifications which can be studied by any man who desires to study them is true enough. That such a study is as much required for determining their characters as it is for determining those of carbon dioxide or of the const.i.tution of Great Britain is also the contention of the paper. But if the words quoted suggest to anyone that the real or even the ideal are somehow possessions of an individual man, things secreted somewhere about him and then ejected, I can only say that I cannot understand the doctrine. I know of no ready-made and antecedent conception of "the individual man." Instead of telling about the nature of experience by means of a prior conception of individual man, I find it necessary to go to experience to find out what is meant by "individual" and by "man"; and also by "the." Consequently even in such an expression as "my experience," I should wish not to contradict this idea of method by using the term "my" to swallow up the term "experience," any more than if I said "my house," or "my country." On the contrary, I should expect that any intelligible and definite use of such phrases would throw much more light upon "me" than upon "house" or "country"--or "experience."

The possible misunderstanding is, I think, actual in the reference to "our needs" as a criterion of the correctness of truth of an idea or plan. According to the essays, it is the needs of a _situation_ which are determinative. They evoke thought and the need of knowing, and it is only within the situation that the identification of the needs with a self occurs; and it is only by reflection upon the place of the agent in the encompa.s.sing situation that the nature of _his_ needs can be determined. In fact, the actual occurrence of a disturbed, incomplete, and needy _situation_ indicates that _my_ present need is precisely to investigate, to explore, to hunt, to pull apart things now tied together, to project, to plan, to invent, and then to test the outcome by seeing how it works as a method of dealing with hard facts. One source of the demand, in short, for reference to experience as the encompa.s.sing universe of discourse is to keep us from taking such terms as "self," "my," "need," "satisfaction," etc., as terms whose meanings can be accepted and proved either by themselves or by even the most extensive dialectic reference to other terms.

Terms like "real" and "ideal," "individual," "man," "my," certainly allow of profitable dialectic (or purely prepositional) clarification and elaboration. But nothing is settled until these discursive findings have been applied, through action, to things, and an experience has been effected, which either meets or evades the specification conceptually laid down. To suppose, for example, that the import of the term "ideal" can be settled apart from exhibiting in experience some specific affair, is to maintain in philosophy that belief in the occult essence and hidden cause which science had to get rid of before it got on the right track. The idealistic misconception of experience is no reason for throwing away its significant point of contact with modern science and for having recourse then to objects distinguished from old-fas.h.i.+oned _Dinge an Sich_ only because they involve just that reference to those experiences by which they were established and to which they are applied that propositional or a.n.a.lytic realism professedly and elaborately ignores. In revenge, this ignoring leaves on our hands the "me," or knowing self, as a separate thing within which experience falls (instead of its falling in a specifiable place within experience), and generates the insoluble problem of how a subjective experience can beget objective knowledge.

In concluding, let me say that reference to experience seems at present to be the easiest way of realizing the continuities among subject-matters that are always getting split up into dualisms. A creation of a world of subsistences or essences which are quite other than the world of natural existences (which are other than natural existences adapted to the successful performance of inference) is in itself a technical matter, though a discouraging one to a philosopher expertly acquainted with all the difficulties which that view has generated from the time of Plato down. But the a.s.sistance which such a philosophy lends to the practical and current divorce of the "ideal" from the natural world makes it a thing to be dreaded for other than professional reasons. G.o.d only knows how many of the sufferings of life are due to a belief that the natural scene and operations of our life are lacking in ideal import, and to the consequent tendency to flee for the lacking ideal factors to some other world inhabited exclusively by ideals. That such a cut-off, ideal world is impotent for direction and control and change of the natural world follows as a matter of course. It is a luxury; it belongs to the "genteel tradition" of life, the persistence of an "upper" cla.s.s given to a detached and parasitic life. Moreover, it places the scientific inquirer within that irresponsible cla.s.s. If philosophers could aid in making it clear to a troubled humanity that ideals are continuous with natural events, that they but represent their possibilities, and that recognized possibilities form methods for a conduct which may realize them in fact, philosophers would enforce the sense of a social calling and responsibility. I do not say that pointing out the continuity and interaction of various att.i.tudes and interests in experience is the only way of effecting this consummation. But for a large number of persons today it is the readiest way.

Much may be said about that other great rupture of continuity which a.n.a.lytic realism would maintain: that between the world and the knower as something outside of it, engaged in an otiose contemplative survey of it. I can understand the social conditions which generated this conception of an aloof knower. I can see how it protected the growth of responsible inquiry which takes effect in change of the environment, by cultivating a sense of the innocuousness of knowing, and thus lulling to sleep the animosity of those who, being in control, had no desire to permit reflection which had practical import. I can see how specialists at any time, professional knowers, so to speak, find in this doctrine a salve for conscience--a solace which all thinkers need as long as an effective share in the conduct of affairs is not permitted them. Above all, I can see how seclusion and the absence of the pressure of immediate action developed a more varied curiosity, greater impartiality, and a more generous outlook.

But all this is no reason for continuing the idealization of a remote and separate mind or knower now that the method of intelligence is perfected, and changed social conditions not only permit but demand that intelligence be placed within the procession of events. An intellectual integrity, an impartiality and detachment, which is maintained only in seclusion is unpleasantly reminiscent of other identifications of virtue with the innocence of ignorance. To place knowledge where it arises and operates in experience is to know that, as it arose because of the troubles of man, it is confirmed in reconstructing the conditions which occasioned those troubles.

Genuine intellectual integrity is found in experimental knowing. Until this lesson is fully learned, it is not safe to dissociate knowledge from experiment nor experiment from experience.

FOOTNOTES:

[1] I am indebted to an unpublished ma.n.u.script of Mr. S. Klyce of Winchester, Ma.s.sachusetts, for the significance of the fact that our words divide into _terms_ (of which more in the sequel) and into names which are not (strictly speaking) terms at all, but which serve to remind us of the vast and vague continuum, select portions of which only are designated by words as _terms_. He calls such words "infinity and zero" words. The word "experience" is a typical instance of an "infinity word." Mr. Klyce has brought out very clearly that a direct situation of experience ("situation" as I employ it is another such word) has no need of any word for itself, the thing to which the word would point being so egregiously there on its own behalf. But when communication about it takes place (as it does, not only in converse with others, but when a man attempts a mutual reference of different periods of his own life) a word is needed to remind both parties of this taken-for-granted whole (another infinity term), while confusion arises if explicit attention is not called to the fact that it is a very different sort of word from the definite terms of discourse which denote distinctions and their relations to one another. In the text, attention is called to the fact that the business man wrestling with a difficulty or a scientific man engaged in an inquiry finds his checks and control specifically in the situation in which he is employed, while the theorizer at large leaves out these checks and limits, and so loses his clews. Well, the words "experience," "situation," etc., are used to _remind_ the thinker of the need of reversion to precisely something which never can be one of the terms of his reflection but which nevertheless furnishes the existential meaning and status of them all. "Intuition," mysticism, philosophized or sophisticated monism, are all of them aberrant ways of protesting against the consequences which result from failing to note what is conveyed by words which are not terms. Were I rewriting these essays _in toto_ I should try to take advantage of these and other indispensable considerations advanced by Mr. Klyce; but as the essays must stand substantially as they were originally written, and as an Introduction to them must, in order to be intelligible, be stated in not incongruous phraseology, I wish simply to ask the reader to bear in mind this radical difference between such words as "experience,"

"reality," "universe," "situation," and such terms as "typewriter,"

"me," "consciousness," "existence," when used (as they must be used if they are to be terms) in a differential sense. The term "reality" is particularly treacherous, for the careless tradition of philosophy (a carelessness fostered, I am sure, by failure to make verbally explicit the distinction to which Mr. Klyce has called attention) uses "reality" both as a term of indifferent reference, equivalent to everything taken together or referred to _en ma.s.se_ as over against some discrimination, and also as a discriminative term with a highly eulogistic flavor: as _real_ money in distinction from counterfeit money. Then, although every inquiry in daily life, whether technological or scientific, asks _whether_ a thing is real only in the sense of asking _what_ thing is real, philosophy concludes to a wholesale distinction between the real and the unreal, the real and the apparent, and so creates a wholly artificial problem.

If the philosopher, whether idealistic or realistic, who holds that it is self-contradictory to criticize purely intellectualistic conceptions of the world, because the criticism itself goes on intellectualistic terms, so that its validity depends upon intellectual (or cognitive) conditions, will but think of the very brute doings in which a chemist engages to fix the meanings of his terms and to test his theories and conceptions, he will perceive that all intellectual knowing is but a method for conducting an experiment, and that arguments and objections are but stimuli to induce somebody to try a certain experiment--to have recourse, that is, to a non-logical non-intellectual affair. Or again, the argument is an invitation to him to note that at the very time in which he is thinking, his thinking is set in a continuum which is not an object of thought. The importance attached to the word "experience," then, both in the essays and in this Introduction, is to be understood as an invitation to employ thought and discriminative knowledge as a means of plunging into something which no argument and no term can express; or rather as an invitation to note the fact that no plunge is needed, since one's own thinking and explicit knowledge are already const.i.tuted by and within something which does not need to be expressed or made explicit. And finally, there is nothing mystical about this, though mysticism doubtless roots in this fact. Its import is only to call notice to the meaning of, say, formulae communicated by a chemist to others as the result of his experiment. All that can be communicated or expressed is that one believes such and such a thing. The communication has scientific instead of merely social significance because the communicated formula is a direction to other chemists to try certain procedures and see what they get. The _direction_ is capable of expression; the result of the experiment, the experience, to which the propositions refer and by which they are tested, is not expressible. (Poetry, of course, is a more competent organ of suggesting it than scientific prose.) The word "experience"

is, I repeat, a notation of an inexpressible as that which decides the ultimate status of all which is expressed; inexpressible not because it is so remote and transcendent, but because it is so immediately engrossing and matter of course.

[2] There are certain points of similarity between this doctrine and that of Holt regarding contradictions and that of Montague regarding "consciousness" as a case of potential energy. But the latter doctrine seems to me to suffer, first, from an isolation of the brain from the organism, which leads to ignoring the active doing, and, secondly, from an isolation of the "moment" of reduction of actual to potential energy. It appears as a curiously isolated and self-sufficient event, instead of as the focus of readjustment in an organized activity at the pivotal point of maximum "tension"--that is, of greatest inhibition in connection with greatest tendency to discharge. And while I think Holt is wholly right in connecting the possibility of error with objectively plural and conflicting forces, I should hardly regard it as linguistically expedient to call counterbalancing forces "contradictory." The counterbalancing forces of the vaulting do not seem to me contradictory in the arch. But if their presence led me to attempt to say "up" and "down" at the same time there would be contradiction. But even admitting that contradictory propositions are merely about forces which are contradictory--heating and cooling--it is still a long way to error. For propositions about such "contradictions" are obviously true propositions. It is only when we make that reaction to one factor which is appropriate to dealing with the other that there is error; and this can happen where there are no contradictory forces at all beyond the fact that the _agent_ is pulled two incompatible and opposed ways at the same time.

[3] For emphasis I am here exaggerating by condensing into a single decisive act an operation which is continuously going on.

[4] I would remark in pa.s.sing that a recognition that a thing may be continuous in one respect and discrete in another would obviate a good many difficulties.

[5] In effect, the fallacy is the same as that of an idealistic theory which holds that all objects are "really" a.s.sociations of sensations.

[6] This statement is meant literally. The "sensations" of color, sound, etc., to which appeal is made in a scientific inquiry are nothing mental in structure or stuff; they are actual, extra-organic things a.n.a.lyzed down to what is so indubitably there that it may safely be taken as a basis of inference.

[7] A term is not of course a mere word; a mere word is non-sense, for a sound by itself is not a word at all. Nor is it a mere meaning, which is not even natural non-sense, being (if it be at all) supernatural or transcendental nonsense. "Terms" signify that certain absent existences are indicated by certain given existences, in the respect that they are abstracted and fixed for intellectual use by some physically convenient means, such as a sound or a muscular contraction of the vocal organs.

[8] This distinction of indication as existential and implication as conceptual or essential, I owe to Mr. Alfred Sidgwick. See his _Fallacies_, p. 50.

[10] I have even seen, in a criticism of the essays, the method of genesis opposed to the method of experimentation--as if experimentation were anything but the generation of some special object!

II

THE RELATIONs.h.i.+P OF THOUGHT AND ITS SUBJECT-MATTER

No one doubts that thought, at least reflective as distinct from what is sometimes called const.i.tutive thought, is derivative and secondary.

It comes after something and out of something, and for the sake of something. No one doubts that the thinking of everyday practical life and of science is of this reflective type. We think about; we reflect over. If we ask what it is which is primary and radical to thought; if we ask what is the final objective for the sake of which thought intervenes; if we ask in what sense we are to understand thought as a derived procedure, we are plunging ourselves into the very heart of the logical problem: the relation of thought to its empirical antecedents and to its consequent, truth, and the relation of truth to reality.

Yet from the nave point of view no difficulty attaches to these questions. The antecedents of thought are our universe of life and love; of appreciation and struggle. We think about anything and everything: snow on the ground; the alternating clanks and thuds that rise from below; the relation of the Monroe Doctrine to the embroglio in Venezuela; the relation of art to industry; the poetic quality of a painting by Botticelli; the battle of Marathon; the economic interpretation of history; the proper definition of cause; the best method of reducing expenses; whether and how to renew the ties of a broken friends.h.i.+p; the interpretation of an equation in hydrodynamics, etc.

Through the madness of this miscellaneous citation there appears so much of method: anything--event, act, value, ideal, person, or place--may be an object of thought. Reflection busies itself alike with physical nature, the record of social achievement, and the endeavors of social aspiration. It is with reference to _such_ affairs that thought is derivative; it is with reference to them that it intervenes or mediates. Taking some part of the universe of action, of affection, of social construction, under its special charge, and having busied itself therewith sufficiently to meet the special difficulty presented, thought releases that topic and enters into further more direct experience.

Sticking for a moment to this nave standpoint, we recognize a certain rhythm of direct practice and derived theory; of primary construction and of secondary criticism; of living appreciation and of abstract description; of active endeavor and of pale reflection. We find that every more direct primary att.i.tude pa.s.ses upon occasion into its secondary deliberative and discursive counterpart. We find that when the latter has done its work it pa.s.ses away and pa.s.ses on. From the nave standpoint such rhythm is taken as a matter of course. There is no attempt either to state the nature of the occasion which demands the thinking att.i.tude, or to formulate a theory of the standard by which is judged its success. No general theory is propounded as to the exact relations.h.i.+p between thinking and what antecedes and succeeds it. Much less do we ask how empirical circ.u.mstances can generate rationality of thought; nor how it is possible for reflection to lay claim to power of determining truth and thereby of constructing further reality.

If we were to ask the thinking of nave life to present, with a minimum of theoretical elaboration, its conception of its own practice, we should get an answer running not unlike this: Thinking is a kind of activity which we perform at specific need, just as at other need we engage in other sorts of activity: as converse with a friend; draw a plan for a house; take a walk; eat a dinner; purchase a suit of clothes, etc. In general, its material is anything in the wide universe which seems to be relevant to this need--anything which may serve as a resource in defining the difficulty or in suggesting modes of dealing effectively with it. The measure of its success, the standard of its validity, is precisely the degree in which the thinking actually disposes of the difficulty and allows us to proceed with more direct modes of experiencing, that are forthwith possessed of more a.s.sured and deepened value.

If we inquire why the nave att.i.tude does not go on to elaborate these implications of its own practice into a systematic theory, the answer, on its own basis, is obvious. Thought arises in response to its own occasion. And this occasion is so exacting that there is time, as there is need, only to do the thinking which is needed in that occasion--not to reflect upon the thinking itself. Reflection follows so naturally upon its appropriate cue, its issue is so obvious, so practical, the entire relations.h.i.+p is so organic, that once grant the position that thought arises in reaction to specific demand, and there is not the particular type of thinking called logical theory because there is not the practical demand for reflection of that sort. Our attention is taken up with particular questions and specific answers.

What we have to reckon with is not the problem of, How can I think _uberhaupt_? but, How shall I think right _here and now_? Not what is the test of thought at large, but what validates and confirms _this_ thought?

In conformity with this view, it follows that a generic account of our thinking behavior, the generic account termed logical theory, arises at historic periods in which the situation has lost the organic character above described. The general theory of reflection, as over against its concrete exercise, appears when occasions for reflection are so overwhelming and so mutually conflicting that specific adequate response in thought is blocked. Again, it shows itself when practical affairs are so multifarious, complicated, and remote from control that thinking is held off from successful pa.s.sage into them.

Anyhow (sticking to the nave standpoint), it is true that the stimulus to that particular form of reflective thinking termed logical theory is found when circ.u.mstances require the act of thinking and nevertheless impede clear and coherent thinking in detail; or when they occasion thought and then prevent the results of thinking from exercising directive influence upon the immediate concerns of life.

Under these conditions we get such questions as the following: What is the relation of rational thought to crude or unreflective experience?

What is the relation of thought to reality? What is the barrier which prevents reason from complete penetration into the world of truth?

What is it that makes us live alternately in a concrete world of experience in which thought as such finds not satisfaction, and in a world of ordered thought which is yet only abstract and ideal?

It is not my intention here to pursue the line of historical inquiry thus suggested. Indeed, the point would not be mentioned did it not serve to fix attention upon the nature of the logical problem.

It is in dealing with this latter type of question that logical theory has taken a turn which separates it widely from the theoretical implications of practical deliberation and of scientific research.

The two latter, however much they differ from each other in detail, agree in a fundamental principle. They both a.s.sume that every reflective problem and operation arises with reference to some _specific_ situation, and has to subserve a _specific_ purpose dependent upon its own occasion. They a.s.sume and observe distinct limits--limits from which and to which. There is the limit of origin in the needs of the particular situation which evokes reflection.

There is the limit of terminus in successful dealing with the particular problem presented--or in retiring, baffled, to take up some other question. The query that at once faces us regarding the nature of logical theory is whether reflection upon reflection shall recognize these limits, endeavoring to formulate them more exactly and to define their relations.h.i.+ps to each other more adequately; or shall it abolish limits, do away with the matter of specific conditions and specific aims of thought, and discuss thought and its relation to empirical antecedents and rational consequents (truth) at large?

At first blush, it might seem as if the very nature of logical theory as generalization of the reflective process must of necessity disregard the matter of particular conditions and particular results as irrelevant. How, the implication runs, could reflection become generalized save by elimination of details as irrelevant? Such a conception in fixing the central problem of logic fixes once for all its future career and material. The essential business of logic is henceforth to discuss the relation of thought as such to reality as such. It may, indeed, involve much psychological material, particularly in the discussion of the processes which antecede thinking and which call it out. It may involve much discussion of the concrete methods of investigation and verification employed in the various sciences. It may busily concern itself with the differentiation of various types and forms of thought--different modes of conceiving, various conformations of judgment, various types of inferential reasoning. But it concerns itself with any and all of these three fields, not on their own account or as ultimate, but as subsidiary to the main problem: the relation of thought as such, or at large, to reality as such, or at large. Some of the detailed considerations referred to may throw light upon the terms under which thought transacts its business with reality; upon, say, certain peculiar limitations it has to submit to as best it may. Other considerations throw light upon the ways in which thought gets at reality. Still other considerations throw light upon the forms which thought a.s.sumes in attacking and apprehending reality. But in the end all this is incidental. In the end the one problem holds: How do the specifications of thought as such hold good of reality as such? In fine, logic is supposed to grow out of the epistemological inquiry and to lead up to its solution.

From this point of view various aspects of logical theory are well stated by an author whom later on we shall consider in some detail.

Lotze[11] refers to "universal forms and principles of thought which hold good everywhere both in judging of reality and in weighing possibility, _irrespective of any difference in the objects_." This defines the business of _pure_ logic. This is clearly the question of thought as such--of thought at large or in general. Then we have the question "of how far the most complete structure of thought ... can claim to be an adequate account of that which we seem compelled to a.s.sume as the object and occasion of our ideas." This is clearly the question of the relation of thought at large to reality at large. It is epistemology. Then comes "applied logic," having to do with the actual employment of concrete forms of thought with reference to investigation of specific topics and subjects. This "applied" logic would, if the standpoint of practical deliberation and of scientific research were adopted, be the sole genuine logic. But the existence of thought _in itself_ having been agreed upon, we have in this "applied"

logic only an incidental inquiry of how the particular resistances and oppositions which "pure" thought meets from particular matters may best be discounted. It is concerned with methods of investigation which obviate defects in the relations.h.i.+p of thought at large to reality at large, as these present themselves under the limitations of human experience. It deals merely with hindrances, and with devices for overcoming them; it is directed by considerations of utility. When we reflect that this field includes the entire procedure of practical deliberation and of concrete scientific research, we begin to realize something of the significance of the theory of logic which regards the limitations of specific origination and specific outcome as irrelevant to its main problem, which a.s.sumes an activity of thought "pure" or "in itself," that is, "irrespective of any difference in its objects."

This suggests, by contrast, the opposite mode of stating the problem of logical theory. Generalization of the nature of the reflective process certainly involves elimination of much of the specific material and contents of the thought-situations of daily life and of critical science. Quite compatible with this, however, is the notion that it seizes upon _certain_ specific conditions and factors, and aims to bring them to clear consciousness--not to abolish them. While eliminating the particular material of particular practical and scientific pursuits, (1) it may strive to hit upon the common denominator in the various situations which are antecedent or primary to thought and which evoke it; (2) it may attempt to show how typical features in the specific antecedents of thought call out diverse typical modes of thought-reaction; (3) it may attempt to state the nature of the specific consequences in which thought fulfils its career.

(1) It does not eliminate dependence upon specific occasions as provocative of thought, but endeavors to define _what_ in the various occasions renders them thought-provoking. The specific occasion is not eliminated, but insisted upon and brought into the foreground.

Consequently, empirical considerations are not subsidiary incidents, but are of essential importance so far as they enable us to trace the generation of the thought-situation. (2) From this point of view the various types and modes of conceiving, judging, and inference are treated, not as qualifications of thought _per se_ or at large, but of reflection engaged in its specific, most economic, effective response to its own particular occasion; they are adaptations for control of stimuli. The distinctions and cla.s.sifications that have been acc.u.mulated in "formal" logic are relevant data; but they demand interpretation from the standpoint of use as organs of adjustment to material antecedents and stimuli. (3) Finally the question of validity, or ultimate objective of thought, is relevant; but relevant as a matter of the specific issue of the specific career of a thought-function. All the typical investigatory and verificatory procedures of the various sciences indicate the ways in which thought actually brings to successful fulfilment its dealing with various types of problems.

While the epistemological type of logic may, as we have seen, leave (under the name of applied logic) a subsidiary place open for the instrumental type, the type which deals with thinking as a specific procedure relative to a specific antecedent occasion and to a subsequent specific fulfilment is not able to reciprocate the favor.

From its point of view, an attempt to discuss the antecedents, data, forms, and objectives of thought, apart from reference to particular position occupied and particular part played in the growth of experience, is to reach results which are not so much either true or false as they are radically meaningless--because they are considered apart from limits. Its results are not only abstractions (for all theorizing ends in abstractions), but abstractions without possible reference or bearing. From this point of view, the taking of something (whether that something be a thinking activity, its empirical stimulus, or its objective goal), apart from the limits of a historic or developing situation, is the essence of _metaphysical_ procedure--in that sense of metaphysics which makes a gulf between it and science.

As the reader has doubtless antic.i.p.ated, it is the object of this chapter to present the problem and industry of reflective thought from the standpoint of nave experience, using the term in a sense wide enough to cover both practical procedure and concrete scientific research. I resume by saying that this point of view knows no fixed distinction between the empirical things and values of unreflective life and the most abstract process of rational thought. It knows no fixed gulf between the highest flight of theory and a control of the details of practical construction and behavior. It pa.s.ses, according to the occasion and opportunity of the moment, from the att.i.tude of loving and struggling and doing to that of thinking and the reverse.

Its contents or material s.h.i.+ft their values back and forth from technological or utilitarian to aesthetic, ethical, or affectional. It utilizes data of perception, of meaning or of discursive ideation as need calls, just as an inventor now utilizes heat, now mechanical strain, now electricity, according to the demands set by his aim.

Anything from past experience may be taken which appears to be an element in either the statement or the solution of the present problem. Thus we understand the coexistence, without contradiction, of an indeterminate possible field and a limited actual field. The undefined range of possible materials becomes specific through reference to an end.

In all this, there is no difference of kind between the methods of science and those of the plain man. The difference is the greater control by science of the statement of the problem, and of the selection and use of relevant material, both sensible and conceptual.

The two are related to each other just as the hit-or-miss, trial-and-error inventions of uncivilized man stand to the deliberate and consecutively persistent efforts of a modern inventor to produce a certain complicated device for doing a comprehensive piece of work.
