1. The existence of inference is a fact, a fact as certain and unquestioned as the existence of eyes or ears or the growth of plants, or the circulation of the blood. One observes it taking place everywhere where human beings exist. A student of the history of man finds that history is composed of beliefs, inst.i.tutions, and customs which are inexplicable without acts of inference. This fact of inference is as much a datum--a hard fact--for logical theory as any sensory quality whatsoever. It is something men do as they walk, chew, or jump. There is nothing a priori or ideological about it. It is just a brute empirically observable event.
2. Its importance is almost as conspicuous as its existence. Every act of human life, not springing from instinct or mechanical habit, contains it; most habits are dependent upon some amount of it for their formation, as they are dependent upon it for their readaptation to novel circ.u.mstances. From the humblest act of daily life to the most intricate calculations of science and the determination and execution of social, legal, and political policies, things are used as signs, indications, or evidence from which one proceeds to something else not yet directly given.
3. The act of inferring takes place naturally, i.e., without intention. It is at first something we do, not something which we _mean_ to do. We do it as we breathe or walk or gesture. Only after it is done do we notice it and reflect upon it--and the great ma.s.s of men no more reflect upon it after its occurrence than they reflect upon the process of walking and try to discover its conditions and mechanism. That an individual, an animal organism, a man or a woman performs the acts is to say something capable of direct proof through appeal to observation; to say that something called mind, or consciousness does it is itself to employ inference and dubious inference. The fact of inference is much surer, in other words, than that of a particular inference, such as that to something called reason or consciousness, in connection with it; save as mind is but another word for the fact of inference, in which case of course it cannot be re-referred to as its cause, source, or author. Moreover, by all principles of science, inference cannot be referred to mind or consciousness as its condition, unless there is _independent_ proof of the existence of that mind to which it is referred. Prima facie we are conscious or aware _of_ inference precisely as we are of anything else, not by introspection of something within the very consciousness which is supposed to be its source, but by observation of something taking place in the world--as we are conscious of walking _after_ we have walked. After it has been done naturally--or "unconsciously"--it may be done "consciously," that is, with intent or on purpose. But this means that it is done _with_ consciousness (whatever consciousness may be discovered to mean), not that it is done _by_ consciousness. Now if other natural events characteristic only (so far as can be ascertained) of highly organized beings are marked by unique or by distinctive traits, there is good ground for the a.s.sumption that inference will be so marked. As we do not find the circulation of blood or the stimulation of nerves in a stone, and as we expect as a matter of course to find peculiar conditions, qualities, and consequences in the being where such operations occur, so we do not find the act of inference in a stone, and we expect peculiar conditions, qualities, and consequences in whatever beings perform the act. Unless, in other words, all the ordinary canons of inquiry are suspended, inference is not an isolated nor a merely formal event. As against the latter, it has its own distinctive structure and properties; as against the former, it has specific generating conditions and specific results.
4. Possibly all this seems too obvious for mention. But there is often a virtual conspiracy in philosophy, not to mention obvious things nor to dwell upon them: otherwise remote speculations might be brought to a sudden halt. The point of these commonplaces resides in the push they may give anyone to engage in a search for _distinctive features in the act of inference_. The search may perhaps be best initiated by noting the seeming inconsistency between what has been said about inference as an art and inference as a natural, unpremeditated occurrence. The obvious function of spontaneous inference is to bring before an agent absent considerations to which he may respond as he otherwise responds to the stimulating force of the given situation. To infer rain is to enable one to behave _now_ as given conditions would not otherwise enable him to conduct himself. This instigation to behave toward the remote in s.p.a.ce or time is the primary trait of the inferential act; descriptively speaking, the act consists in taking up an att.i.tude of response to an absent thing as if it were present. But just because the thing is absent, the att.i.tude taken may be either irrelevant and positively harmful or extremely pertinent and advantageous. We may infer rain when rain is not going to happen, and acting upon the inference be worse off than if there had been no inference. Or we may make preparations, which we would not otherwise have made; the rain may come, and the inference save our lives--as the ark saved Noah. Inference brings, in short, truth and falsity into the world, just as definitely as the circulation of the blood brings its distinctive consequences, both advantages and liabilities into the world, or as the existence of banking brings with it consequences of business extension and of bankruptcy not previously existent. If the reader objects to the introduction of the terms "truth" and "falsity", I am perfectly willing to leave the choice of words to him, provided the fact is recognized that through inference men are capable of a kind of success and exposed to a kind of failure not otherwise possible: dependent upon the fact that inference takes absent things as being in a certain real continuum with present things, so that our att.i.tude toward the latter is bound up with our reaction to the former as parts of the same situation. And in any event, I wish to protest against a possible objection to the introduction of the terms "false" and "true." It may be said that inference is not responsible for the occurrence of errors and truths, because these accompany simple apprehensions where there is no inference: as when I see a snake which isn"t there--or any other case which may appear to the objector to afford an ill.u.s.tration of his point. The objection ill.u.s.trates my point. To affirm a snake is to affirm potentialities going beyond what is actually given; it says that what is given is _going_ to do something--the doing characteristic of a snake, so that we are to react to the given as to a snake. Or if we take the case of a face in the cloud recognized as a phantasy; then (to say nothing of "in the cloud" which involves reference beyond the given) "phantasy,"
"dream," equally means a reference to objects and considerations _not_ given as the actual datum is given.
We have not got very far with our question of distinctive, unique traits called into existence by inference, but we have got far enough to have light upon what is called the "transcendence" of knowledge.
All inference is a _going beyond_ the a.s.suredly present to an absent.
Hence it is a more or less precarious journey. It is transcending limits of security of immediate response. The stone which reacts only to stimuli of the present, not of the future, cannot make the mistakes which a being reacting to a future taken to be connected with the present is sure to make. But it is important to note just what this transcendence consists in. It has nothing to do with transcending mental states to arrive at an external object. _It is behaving to the given situation as involving something not given._ It is Robinson Crusoe going from a seen foot to an unseen man, not from a mental state to something unmental.
5. The mistakes and failures resulting from inference const.i.tute the ground for transition from natural spontaneous performance to a technique or deliberate art of inference. There is something humorous about the discussion of the problem of error as if it were a rare or exceptional thing--an anomaly--when the barest glance at human history shows that mistakes have been the rule, and that truth lies at the bottom of a well. As to inferences bound up with barely keeping alive, man has had to effect a considerable balance of good guesses over bad.
Aside from this somewhat narrow field, the original appearance of inference upon the scene probably added to the interest of life rather than to its efficiency. If the cla.s.sic definition of man as a rational animal means simply an inferring or guessing animal, it applies to the natural man, for it allows for the guesses being mostly wrong. If it is used with its customary eulogistic connotations, it applies only to man chastened to the use of a hardly won and toilsome art. If it alleges that man has any natural preference for a reasonable inference or that the rationality of an inference is a measure of its hold upon him, it is grotesquely wrong. To propagate this error is to encourage man in his most baleful illusion, and to postpone the day of an effective and widespread adoption of a perfected art of knowing.
Summarily put, the waste and loss consequent upon the natural happening of inference led man, slowly and grudgingly, to the adoption of safeguards in its performance. In some part, the scope of which is easily exaggerated, man has come to attribute many of the ills from which he suffers to his own premature, inept, and unguarded performing of inference, instead of to fate, bad luck, and accident. In some things, and to some extent in all things, he has invented and perfected an art of inquiry: a system of checks and tests to be used before the conclusion of inference is categorically affirmed. Its nature has been considered in many other places in these pages, but it may prove instructive to restate it in this context.
_a_) Nothing is less adapted to a successful accomplishing of an inference than the subject-matter from which it ordinarily fares forth. That subject-matter is a nest of obscurities and ambiguities.
The ordinary warnings against trusting to imagination, the bad name which has come intellectually to attach to fancy, are evidences that anything may suggest anything. Regarding most of the important happenings in life no inference has been too extravagant to obtain followers and influence action, because subject-matter was so variegated and complex that any objects which it suggested had a prima facie plausibility. That every advance in knowledge has been effected by using agencies which break up a complex subject-matter into independent variables (from each of which a distinct inference may be drawn), and by attacking each one of these things by every conceivable tool for further resolution so as to make sure we are dealing with something so simple as to be unambiguous, is the report of the history of science. It is sometimes held that knowledge comes ultimately to a necessity of belief, or acceptance, which is the equivalent of an incapacity to think otherwise than so and so. Well, even in the case of such an apparently simple "self-evident" thing as a red, this inability, if it is worth anything, is a residuum from experimental a.n.a.lysis. We do not believe in the thing as red (whenever there is a need of scientific testing) till we have exhausted all kinds of active attack and find the red still resisting and persisting. Ordinarily we move the head; we shade the eyes; we turn the thing over; we take it to a different light. The use of lens, prism, or whatever device, is simply carrying farther the use of like methods as of physical resolution. Whatever endures all these active (not mental) attacks, we accept--pending invention of more effective weapons. To make sure that a given fact _is_ just and such a shade of red is, one may say, a final triumph of scientific method. To turn around and treat it as something naturally or psychologically given is a monstrous superst.i.tion.
When a.s.sured, such a simple datum is for the sake of guarding the act of inference. Color may mean a lot of things; any red may mean a lot of things; such things are ambiguous; they afford unreliable evidence or signs. To get the color down to the last touch of possible discrimination is to limit its range of testimony; ideally, it is to secure a voice which says but one thing and says that unmistakably.
Its simplicity is not identical with isolation, but with _specified_ relationship. Thus the hard "facts," the brute data, the simple qualities or ideas, the sense elements of traditional and of contemporary logic, get placed and identified within the art of controlling inference. The allied terms "self-evident," "sensory truths," "simple apprehensions" have their meanings unambiguously determined in this same context; while apart from it they are the source of all kinds of error. They are no longer notions to conjure with. They express the last results attainable by present physical methods of discriminative a.n.a.lysis employed in the search for dependable data for inference. Improve the physical means of experimentation, improve the microscope or the registering apparatus or the chemical reagent, and they may be replaced tomorrow by new, simple apprehensions of simple and ultimate data.
_b_) Natural or spontaneous inference depends very largely upon the habits of the individual in whom inferring takes place. These habits depend in turn very largely upon the customs of the social group in which he has been brought up. An eclipse suggests very different things according to the rites, ceremonies, legends, traditions, etc., of the group to which the spectator belongs. The average layman in a civilized group may have no more personal science than an Australian Bushman, but the legends which determine his reactions are different.
His inference is better, neither because of superior intellectual capacity, nor because of more careful personal methods of knowing, but because his instruction has been superior. The instruction of a scientific inquirer in the best scientific knowledge of his day is just as much a part of the control (or art) of inference as is the technique of observational a.n.a.lysis which he uses. As the bulk of prior ascertainments increases, the tendency is to identify this stock of learning, this store of achieved truth, with knowledge. There is no objection to this identification save as it leads the logician or epistemologist to ignore that which _made_ it "knowledge" (that which gives it a right to the t.i.tle), and as a consequence to fall into two errors: one, overlooking its function in the guidance and handling of future inferences; the other, confusing the mere act of reference to what is known (known so far as it has accrued from prior tested inquiries) with knowing. To remind myself of what is known as to the topic with which I am dealing is an indispensable performance, but to call this reminder "knowing" (as the presentative realist usually does) is to confuse a psychological event with a logical achievement.
It is from misconception of this act of reminding one"s self of what is known, as a check in some actual inquiry, that arise most of the fallacies about simple acquaintance, mere apprehension, etc.--the fallacies which eliminate inquiry and inferring from knowledge.
_c_) The art of inference gives rise to specific features characterizing the _inferred_ thing. The natural man reacts to the suggested thing as he would to something present. That is, he tends to accept it uncritically. The man called up by the footprint on the sand is just as real a man as the footprint is a real footprint. It is a _man_, not the idea of a man, which is indicated. What a thing means is another _thing_; it doesn"t mean a meaning. The only difference is that the thing indicated is farther off, or more concealed, and hence (probably) more mysterious, more powerful and awesome, on that account. The man indicated to Crusoe by the footprints was like a man of menacing powers seen at a distance through a telescope. Things naturally inferred are accepted, in other words, by the natural man on altogether too realistic a basis for adequate control; they impose themselves too directly and irretrievably. There are no alternatives save either acceptance or rejection _in toto_. What is needed for control is some device by which they can be treated for just what they are, namely, _inferred_ objects which, however a.s.sured as objects of _prior_ experiences, are uncertain as to their existence in connection with the object from which present inference sets out. While more careful inspection of the given object--to see if it be really a footprint, how fresh, etc.--may do much for safe-guarding inference; and while forays into whatever else is known may help, there is still need for something else. We need some method of freely examining and handling the object in its status as an inferred object. This means some way of detaching it, as it were, from the particular act of inference in which it presents itself. Without some such detachment, Crusoe can never get into a free and effective relation with the man indicated by the footprint. He can only, so to speak, go on repeating, with continuously increasing fright, "There"s a man about, there"s a man about." The "man" needs to be treated, not as man, but as something having a merely inferred and hence potential status; as a meaning or thought, or "idea." There is a great difference between meaning and _a_ meaning. Meaning is simply a function of the situation: this thing means that thing: meaning is this relationship.
A meaning is something quite different; it is not a function, but a specific ent.i.ty, a peculiar thing, namely the man _as_ suggested.
Words are the great instrument of translating a relation of inference existing between two things into a new kind of thing which can be operated with on its own account; the term of discourse or reflection is the solution of the requirement for greater flexibility and liberation. Let me repeat: Crusoe"s inquiry can play freely around and about the man inferred from the footprint only as he can, so to say, get away from the immediate suggestive force of the footprint. As it originally stands, the man suggested is on the same coercive level as the suggestive footprint. They are related, tied together. But a gesture, a sound, may be used as a _subst.i.tute_ for the thing inferred. It exists independently of the footprint and may therefore be thought about and ideally experimented with irrespective of the footprint. It at once preserves the meaning-force of the situation and detaches it from the immediacy of the situation. It is a meaning, an idea.
Here we have, I submit, the explanation of notions, forms, essences, terms, subsistences, ideas, meanings, etc. They are surrogates of the objects of inference of such a character that they may be elaborated and manipulated exactly as primary things may be, so far as inference is concerned. They can be brought into relation with one another, quite irrespective of the things which originally suggested them.
Without such free play reflective inquiry is mockery, and control of inference an impossibility. When a speck of light suggests to the astronomer a comet, he would have nothing to do but either to accept the inferred object as a real one, or to reject it as a mere fancy unless he could treat "comet" for the time being not as a thing at all, but as a meaning, a conception; a meaning having, moreover, by connection with other meanings, implications--meanings consequent from it. Unless a meaning is an inferred object, detached and fixed as a term capable of independent development, what sort of a ghostly Being is it? Except on the basis stated, what is the transition from the function of meaning to _a_ meaning as an ent.i.ty in reasoning? And, once more, unless there is such a transition, is reasoning possible?
Cats have claws and teeth and fur. They do not have implications. No physical thing has implications. The _term_ "cat" has implications.
How can this difference be explained? On the ground that we cannot use the "cat" object inferred from given indications in such a way as will test the inference and make it fruitful, helpful, unless we can detach it from its existential dependence upon the particular things which suggest it. We need to know what a cat would be _if_ it were there; what other things would also be indicated if the cat is really indicated. We therefore create a _new_ object: we take something to stand for the cat-in-its-status-as-inferred in contrast with the cat as a live thing. A sound or a visible mark is the ordinary mechanism for producing such a new object. Whatever the physical means employed, we now have a new object; a term, a meaning, a notion, an essence, a form or species, according to the terminology which may be in vogue.
It is as much a specific existence as any sound or mark is. But it is a mark which notes, concentrates, and records an outcome of an inference which is not yet accepted and affirmed. That is to say, it designates an object which is _not yet_ to be reacted to as one reacts to the given stimulus, but which is an object of further examination and inquiry, a medium of a postponed conclusion and of investigation continued till better grounds for affirming an object (making a definite, unified response) are given. _A term is an object so far as that object is undergoing shaping in a directed act of inquiry._ It may be called a possible object or a hypothetical object. Such objects do not walk or bite or scratch, but they are nevertheless actually present as the vital agencies of reflection. If we but forget where they live and operate--within the event of controlled inference--we have on our hands all the mysteries of the double world of existence and essence, particular and universal, thing and idea, ordinary life and science. For the world of science, especially of mathematical science, is the world of considerations which have approved themselves to be effectively regulative of the operations of inference. It is easier to wash with ordinary water than with H{2}O, and there is a marked difference between falling off a building and 1/2_gt_^{2}. But H{2}O and 1/2_gt_^{2} are as potent for the distinctive act of inference--as genuine and distinctive an act as washing the hands or rolling down hill--as ordinary water and falling are impotent.
Scientific men can handle these things-of-inference precisely as the blacksmith handles his tools. They are not thoughts as they are ordinarily used, not even in the logical sense of thought. They are rather things whose manipulation (as the blacksmith manipulates his tools) yield knowledge--or methods of knowledge--with a minimum of recourse to thinking and a maximum of efficiency. When one considers the importance of the enterprise of knowledge, it is not surprising that appropriate tools have been devised for carrying it on, and that these tools have no prototypes in pre-existent materials. They are real objects, but they are just the real objects which they are and not some other objects.
THEORY AND PRACTICE
Our last paragraphs have touched upon the nature of science. They contain, by way of intimation, an explanation of the distance which lies between the things of daily intercourse and the terms of science.
Controlled inference is science, and science is, accordingly, a highly specialized industry. It is such a specialized mode of practice that it does not appear to be a mode of practice at all. This high specialization is part of the reason for the current ant.i.thesis of theory and practice, knowledge and conduct, the other part being the survival of the ancient conception of knowledge as intuitive and dialectical--the conception which is set forth in the Aristotelian logic.
Starting from the hypothesis that the art of controlled inference requires for its efficient exercise specially adapted ent.i.ties, it follows that the various sciences are the various forms which the industry of controlled inquiry a.s.sumes. It follows that the conceptions and formulations of the sciences--physical and mathematical--concern things which have been reshaped in view of the exigencies of regulated and fertile inference. To get things into the estate where such inference is practicable, many qualities of the water and air, cats and dogs, stones and stars, of daily intercourse with the world have been dropped or depressed. Much that was trivial or remote has been elevated and exaggerated. Neither the omissions nor the accentuations are arbitrary. They are purposeful. They represent the changes in the things of ordinary life which are needed to safeguard the important business of inference.
There is then a great difference between the ent.i.ties of science and the things of daily life. This may be fully acknowledged. But unless the admission is accompanied by an ignoring of the function of inference, it creates no problem of conciliation, no need of apologizing for either one or the other. It generates no problem of the real and the apparent. The "real" or "true" objects of science are those which best fulfil the demands of secure and fertile inference.
To arrive at them is such a difficult operation, there are so many specious candidates clamoring for the office, that it is no wonder that when the objects suitable for inference are const.i.tuted, they tend to impose themselves as _the_ real objects, in comparison with which the things of ordinary life are but impressions made upon us (according to much modern thought), or defective samples of Being--according to much of ancient thought. But one has only to note that their genuinely characteristic feature is fitness for the aims of inference to awaken from the nightmare of all such problems. They differ from the things of the common world of action and a.s.sociation as the means and ends of one occupation differ from those of another.
The difference is not that which exists between reality and appearance, but is that between the subject-matter of crude occupations and of a highly specialized and difficult art, upon the success of which (so it is discovered) the progress of other occupations ultimately depends.
The ent.i.ties of science are not only _from_ the scientist; they are also _for_ him. They express, that is, not only the outcome of reflective inquiries, but express them in the particular form in which they can enter most directly and efficiently into subsequent inquiries. The fact that they are sustained within the universe of inquiry accounts for their remoteness from the things of daily life, the latter being promptly precipitated out of suspense in such solutions. That most of the immediate qualities of things (including the so-called secondary qualities) are dropped signifies that such qualities have not turned out to be fruitful for inference. That mathematical, mechanical, and "primary" distinctions and relations have come to const.i.tute the proper subject-matter of science signifies that they represent such qualities of original things as are most manipular for knowledge-getting or a.s.sured and extensive inference.
Consider what a hard time the scientific man had in getting away from other qualities, and how the more immediate qualities have been pressed upon him from all quarters, and it is not surprising that he inclines to think of the intellectually useful properties as alone "real" and to relegate all others to a quasi-illusory field. But his victory is now sufficiently achieved so that this tension may well relax; it may be acknowledged that the difference between scientific ent.i.ties and ordinary things is one of function, the former being selected and arranged for the successful conduct of inferential knowings.
I conclude with an attempt to show how bootless the ordinary ant.i.thesis between knowledge (or theory) and practice becomes when we recognize that it really involves only a contrast between the kinds of judgments appropriate to ordinary modes of practice and those appropriate to the specialized industry of knowledge-getting.
It is not true that to insist that scientific propositions fall within the domain of practice is to depreciate them. On its face, the insistence means simply that all knowledge involves experimentation, with whatever appliances are suited to the problem in hand, of an active and physical type. Instead of this doctrine leading to a low estimate of knowledge, the contrary is the case. This art of experimental thinking turns out to give the key to the control and development of other modes of practice. I have touched elsewhere in these essays upon the way in which knowledge is the instrument of regulation of our human undertakings, and I have also pointed out that intrinsic increments of meaning accrue in consequence of thinking. I wish here to point how that mode of practice which is called theorizing emanc.i.p.ates experience--how it makes for steady progress.
No matter how much specialized skill improves, we are restricted in the degree in which our ends remain constant or fixed. Significant progress, progress which is more than technical, depends upon ability to foresee new and different results and to arrange conditions for their effectuation. Science is the instrument of increasing our technique in attaining results already known and cherished. More important yet, it is the method of emanc.i.p.ating us from enslavement to customary ends, the ends established in the past.
Let me borrow from political philosophy a kind of caricature of the facts. As social philosophers used to say that the state came into existence when individuals agreed to surrender some of their native personal rights for the sake of getting the advantages of non-interference and aid from others who made a like surrender, so we might say that science began when men gave up the claim to form the structure of knowledge each from himself as a center and measure of meaning--when there was an agreement to take an impersonal standpoint.
Non-scientific modes of practice, left to their natural growth, represent, in other words, arrangements of objects which cl.u.s.ter about the self, and which are closely tied down to the habits of the self.
Science or theory means a system of objects detached from any particular personal standpoint, and therefore available for any and every possible personal standpoint. Even the exigencies of ordinary social life require a slight amount of such detachment or abstraction.
I must neglect my own peculiar ends enough to take some account of my neighbor if I am going to be intelligible to him. I must at least find common ground. Science systematizes and indefinitely extends this principle. It takes its stand, not with what is common with some particular neighbor living at this especial date in this particular village, but with any possible neighbor in the wide stretches of time and s.p.a.ce. And it does so by the mere fact that it is continually reshaping its peculiar objects with an eye single to availability in inference. The more abstract, the more impersonal, the more impartially objective are _its_ objects, the greater the variety and scope of inference made possible. Every street of experience which is laid out by science has its tracks for transportation, and every line issues transfer checks to every other line. You and I may keep running in certain particular ruts, but conditions are provided for somebody else to foresee--or infer--new combinations and new results. The depersonalizing of the things of everyday practice becomes the chief agency of their repersonalizing in new and more fruitful modes of practice. The paradox of theory and practice is that theory is with respect to all other modes of practice the most practical of all things, and the more impartial and impersonal it is, the more truly practical it is. And this is the sole paradox.
But lest the man of science, the man of dominantly reflective habits, be puffed up with his own conceits, he must bear in mind that practical application--that is, experiment--is a condition of his own calling, that it is indispensable to the inst.i.tution of knowledge or truth. Consequently, in order that he keep his own balance, it is needed that his findings be everywhere applied. The more their application is confined within his own special calling, the less meaning do the conceptions possess, and the more exposed they are to error. The widest possible range of application is the means of the deepest verification. As long as the specialist hugs his own results they are vague in meaning and unsafe in content. That individuals in every branch of human endeavor should be experimentalists engaged in testing the findings of the theorist is the sole final guaranty for the sanity of the theorist.
FOOTNOTES:
[78] _Scientific Method in Philosophy_, p. 57.
[79] The a.n.a.lytic realists have shown a peculiar disinclination to discuss the nature of future consequences as terms of propositions.
They certainly are not identical with the mental act of referring to them; they are "objective" to it. Do they, therefore, already subsist in some realm of subsistence? Or is subsistence but a name for the fact of logical reference, leaving the determination of the meaning of "subsistence" dependent upon a determination of the meaning of "logical"? More generally, what is the position of a.n.a.lytic realism about the future?
[80] Supposing the question to be that of some molten state of the earth in past geologic ages. Taken as the complete subject-matter of a proposition--or science--the facts discovered cannot be regarded as causative of, or a mechanism of, the appearance of life. For by definition they form a closed system; to introduce reference to a future event is to deny the definition. Contrariwise, a statement of that past condition of the earth as a mechanical condition of the later emergence of life means that that past stage is taken not merely as past, but as in process of transition to its future, as in process of alteration in the direction of life. Change in this direction is an integral part of a statement of the early stage of the earth"s history. A purely geologic statement may be quite accurate in its own universe of discourse and yet quite incomplete and hence inaccurate in another universe of discourse. That is to say, a geologist"s propositions may accurately set forth a prior state of things, while ignoring any reference to a later state entailed by them. But a would-be philosophy may not ignore the implied future.

[85] It is perhaps poor tactics on my part to complicate this matter with anything else. But it is evident that "pa.s.sions" and pains and pleasures may be used as _evidences_ of something beyond themselves (as may the fact of being more than five feet high) and so get a representative or cognitive status. Is there not also a prima facie presumption that all sensory qualities are of themselves bare existences or occurrences without cognitive pretension, and that they acquire the latter status as signs or evidence of something else?
Epistemological idealists or realists who admit the non-cognitive character of pleasure and pain would seem to be under special obligations carefully to consider the thesis of the non-cognitive nature of all sensory qualities except as they are employed as indications or indexes of some other thing. This recognition frees logic from the epistemological discussion of secondary qualities.
[86] To readers who have grasped the thought of my argument, it may not be meaningless to say that the typical idealistic fallacy is to import into the direct experience the results of the intellectual or reflective examination, while that of realism is to treat the reflective operation as dealing with precisely the same subject-matter as the original act was concerned with--taking the good of "reason"
and the good of immediate behavior to be the same sort of things. And both fallacies will result from any a.s.similation of two different acts to one another through giving them both the t.i.tle "knowledge," and hence treating the difference between them as simply the difference between a direct apprehension and a mediated one.
[87] a.n.a.lytic realism ought to be favorable to such a hedonism; the fact that present-day a.n.a.lytic realists are not favorable would seem to indicate that they have not taken their logic seriously enough, but have been restrained, by practical motives, from applying it thoroughly. To say that the moral life presents a high degree of organization and integration is to say something which is true, but is also to say something which by the a.n.a.lytic logic calls for its resolution into ultimate and independent simples. Unless they accept the pleasures and pains of Bentham as such ultimates, they are bound to present acceptable subst.i.tutes. But here they tend to shift their logic and to make the fulfilment of some _organization_ (variously defined) the standard good. Consistency would then admit the hypothesis that in _all_ cases an eventual organization rather than antecedent simples supply the standard of knowledge. Meanwhile the term "fulfilment" (or any similar term) stands as an acknowledgment that the organization in question is not something ontologically prior but is one yet to be achieved.
[88] It must not be overlooked that a mere reminder of an end previously settled upon may operate as a sufficient stimulus to action. It is probably this act of calling the end to mind which the realist confuses with knowledge, and therefore terms apprehension. But there is nothing cognitive about it, any more than there is in pressing a b.u.t.ton to give the signal for an act already decided upon.
[89] Upholders of this view generally disguise the a.s.sumption of repet.i.tion by the notion that what is judged is progress in the direction of approximation to an eternal value. But as matter of fact, progress is never judged (as I have had repeated occasion to point out) by reference to a transcendent eternal value, but in reference to the success of the end-in-view in meeting the needs and conditions of the specific situation--a surrender of the doctrine in favor of the one set forth in the text. Logically, the notion of progress as approximation has no place. The thesis should read that we always try to repeat a given value, but always fail as a matter of fact. And constant failure is a queer name for progress.
