THE ANTECEDENTS AND STIMULI OF THINKING
We have discriminated logic in its wider sense--concerned with the sequence of characteristic functions and attitudes in experience--from logic in its stricter meaning, concerned with the function of reflective thought. We must avoid yielding to the temptation of identifying logic with either of these to the exclusion of the other; or of supposing that it is possible to isolate one finally from the other. The more detailed treatment of the organs and methods of reflection cannot be carried on with security save as we have a correct idea of the position of reflection amid the typical functions of experience. Yet it is impossible to determine this larger placing, save as we have a defined and analytic, as distinct from a merely vague and gross, view of what we mean by reflection--what is its actual constitution. It is necessary to work back and forth between the larger and the narrower fields, transforming every increment upon one side into a method of work upon the other, and thereby testing it. The evident confusion of existing logical theory, its uncertainty as to its own bounds and limits, its tendency to oscillate from larger questions of the meaning of judgment and the validity of inference over to details of scientific technique, and to translate distinctions of formal logic into acts in an investigatory or verificatory process, are indications of the need of this double movement.
In the next three chapters it is proposed to take up some of the considerations that lie on the borderland between the larger and the narrower conceptions of logical theory. I shall discuss the _locus_ of the function of thought in experience so far as such _locus_ enables us to characterize some of the most fundamental distinctions, or divisions of labor, within the reflective process. In taking up the problem of the subject-matter of thought, I shall try to make clear that it assumes three quite distinct forms according to the epochal moment reached in control of experience. I shall attempt to show that we must consider subject-matter from the standpoint, first, of the _antecedents_ or conditions that evoke thought; secondly, of the _datum_ or _immediate material_ presented to thought; and, thirdly, of the _proper objective_ of thought. Of these three distinctions the first, that of antecedent and stimulus, clearly refers to the situation that is immediately prior to the thought-function as such. The second, that of datum or immediately given matter, refers to a distinction which is made within the thought-process as a part of and for the sake of its own _modus operandi_. It is a status in the scheme of thinking. The third, that of content or object, refers to the progress actually made in any thought-function; material which is organized by inquiry so far as inquiry has fulfilled its purpose. This chapter will get at the matter of preliminary conditions of thought indirectly rather than directly, by indicating the contradictory positions into which one of the most vigorous and acute of modern logicians, Lotze, has been forced through failing to define logical distinctions in terms of the history of readjustment and control of things in experience, and being thereby compelled to interpret certain notions as absolute instead of as historic and methodological.
Before passing directly to the exposition and criticism of Lotze, it will be well, however, to take the matter in a somewhat freer way. We cannot approach logical inquiry in a wholly direct and uncompromised manner. Of necessity we bring to it certain distinctions--distinctions partly the outcome of concrete experience; partly due to the logical theory which has got embodied in ordinary language and in current intellectual habits; partly results of deliberate scientific and philosophic inquiry. These more or less ready-made results are resources; they are the only weapons with which we can attack the new problem. Yet they are full of unexamined assumptions; they commit us to all sorts of logically predetermined conclusions. In one sense our study of the new subject-matter, let us say logical theory, is in truth only a review, a retesting and criticizing of the intellectual standpoints and methods which we bring with us to the study.
Nowadays everyone comes with certain distinctions already made between the subjective and the objective, between the physical and the mental, between the intellectual and the factual. (1) We have learned to regard the region of emotional disturbance, of uncertainty and aspiration, as belonging peculiarly to ourselves; we have learned to set over against this the world of observation and of valid thought as something unaffected by our moods, hopes, fears, and opinions. (2) We have also come to distinguish between what is immediately present in our experience and the past and the future; we contrast the realms of memory and anticipation with that of sense perception; more generally we contrast the given with the inferential. (3) We are confirmed in a habit of distinguishing between what we call actual fact and our mental attitude toward that fact--the attitude of surmise or wonder or reflective investigation. While one of the aims of logical theory is precisely to make us critically conscious of the significance and bearing of these various distinctions, to change them from ready-made assumptions into controlled conceptions, our mental habits are so set that they tend to have their own way with us; we read into logical theory conceptions that were formed before we had even dreamed of the logical undertaking which after all has for its business to assign to the terms in question their proper meaning. Our conclusions are thus controlled by the very notions which need criticism and revision.
We find in Lotze an unusually explicit inventory of these various preliminary distinctions, and an unusually serious effort to deal with the problems which arise from introducing them into the structure of logical theory. (1) He expressly separates the matter of logical worth from that of psychological genesis. He consequently abstracts the subject-matter of logic as such wholly from the question of historic _locus_ and _situs_. (2) He agrees with common-sense in holding that logical thought is reflective and thus presupposes a given material. He occupies himself with the nature of the antecedent conditions. (3) He wrestles with the problem of how a material formed prior to thought and irrespective of it can yet afford stuff upon which thought may exercise itself. (4) He expressly raises the question of how thought working independently and from without upon a foreign material can shape the latter into results which are valid--that is, objective.
If this discussion is successful; if Lotze can provide the intermediaries which span the gulf between the exercise of logical functions by thought upon a material wholly external to it; if he can show that the question of the origin of subject-matter of thought and of thought-activity is irrelevant to the question of its meaning and validity, we shall have to surrender the position already taken. But if we find that Lotze's elaborations only elaborate the fundamental difficulty, presenting it now in this light and now in that, but always presenting the problem as if it were its own solution, we shall be confirmed in our idea of the need of considering logical questions from a different point of view. If we find that, whatever his formal treatment, he always, as a matter of fact, falls back upon some organized situation or function as the source of both the material and the process of inquiry, we shall have in so far an elucidation and even a corroboration of our theory. We begin with the question of the material antecedents of thought--antecedents which condition reflection, and which call it out as reaction or response, by giving its cue. Lotze differs from many logicians of the same type in furnishing an explicit account of these antecedents.
1. The ultimate material antecedents of thought are found in impressions which are due to external objects as stimuli. Taken in themselves, these impressions are mere psychical states or events. They exist in us side by side, or one after the other, according as the objects which excite them operate simultaneously or successively. The occurrence of these various psychical states is not, however, entirely dependent upon the presence of the exciting thing. After a state has once been excited, it gets the power of reawakening other states which have accompanied it or followed it. The associative mechanism of revival plays a part. If we had a complete knowledge of both the stimulating object and its effects, and of the details of the associative mechanism, we should be able from given data to predict the whole course of any given train or current of ideas (for the impressions as conjoined simultaneously or successively become ideas and a current of ideas). Taken in itself, a sensation or impression is nothing but a "state of our consciousness, a mood of ourselves." Any given current of ideas is a necessary sequence of existences (just as necessary as any succession of material events), happening in some particular sensitive soul or organism. "Just because, under their respective conditions, every such series of ideas hangs together by the same necessity and law as every other, there would be no ground for making any such distinction of value as that between truth and untruth, thus placing one group in opposition to all the others."[13]
2. Thus far, as the last quotation clearly indicates, there is no question of reflective thought, and hence no question of logical theory. But further examination reveals a peculiar property of the current of ideas. Some ideas are merely coincident, while others may be termed coherent. That is to say, the exciting causes of some of our simultaneous and successive ideas really belong together; while in other cases they simply happen to act at the same time, without there being a real connection between them. By the associative mechanism, however, both the coherent and the merely coincident combinations recur. The first type of recurrence supplies positive material for knowledge; the second gives occasion for error. 3. It is a peculiar mixture of the coincident and the coherent which sets the peculiar problem of reflective thought. The business of thought is to recover and confirm the coherent, the really connected, adding to its reinstatement an accessory justifying notion of the real ground of coherence, while it eliminates the coincident as such. While the mere current of ideas is something which just happens within us, the process of elimination and of confirmation by means of statement of real ground and basis of connection is an activity which mind, as such, exercises. This distinction marks off thought as activity from any psychical event and from the associative mechanism as mere happenings. One is concerned with mere _de facto_ coexistences and sequences; the other with the cognitive _worth_ of these combinations.[14]
Consideration of the peculiar work of thought in going over, sorting out, and determining various ideas according to a standard of value will occupy us in our next chapter. Here we are concerned with the material antecedents of thought as they are described by Lotze. At first glance, he seems to propound a satisfactory theory. He avoids the extravagancies of transcendental logic, which assumes that all the matter of experience is determined from the very start by rational thought; and he also avoids the pitfall of purely empirical logic, which makes no distinction between the mere occurrence and association of ideas and the real worth and validity of the various conjunctions thus produced. He allows unreflective experience, defined in terms of sensations and their combinations, to provide material conditions for thinking, while he reserves for thought a distinctive work and dignity of its own. Sense experience furnishes the antecedents; thought has to introduce and develop systematic connection--rationality. A further analysis of Lotze's treatment may, however, lead us to believe that his statement is riddled through and through with inconsistencies and self-contradictions; that, indeed, any one part of it can be maintained only by the denial of some other portion.
1. The impression is the ultimate antecedent in its purest or crudest form (according to the angle from which one views it). It is that which has never felt, for good or for bad, the influence of thought. Combined into ideas, these impressions stimulate or arouse the activities of thought, which are forthwith directed upon them. As the recipient of the activity which they have excited and brought to bear upon themselves, they furnish also the material content of thought--its actual stuff. As Lotze says over and over again: "It is the relations themselves already subsisting between impressions, when we become conscious of them, by which the action of thought which is never anything but reaction, is attracted; and this action consists merely in interpreting relations which we find existing between our passive impressions into aspects of the matter of impressions."[15] And again: "Thought can make no difference where it finds none already in the matter of the impressions."[16] And again: "The possibility and the success of thought's procedure depends upon this original constitution and organization of the whole world of ideas, a constitution which, though not necessary in thought, is all the more necessary to make thinking possible."[17] The impressions and ideas thus play a versatile rôle; they now assume the part of ultimate antecedents and provocative conditions; of crude material; and somehow, when arranged, of content for thought. This very versatility awakens suspicion.
While the impression is merely subjective and a bare state of our own consciousness, yet it is determined, both as to its existence and as to its relation to other similar existences, by external objects as stimuli, if not as causes. It is also determined by a psychical mechanism so thoroughly objective or regular in its workings as to give the same necessary character to the current of ideas that is possessed by any physical sequence. Thus that which is "nothing but a state of our consciousness" turns out straightway to be a specifically determined objective fact in a system of facts. That this absolute transformation is a contradiction is no clearer than that just such a contradiction is indispensable to Lotze. If impressions were nothing but states of consciousness, moods of ourselves, bare psychical existences, it is sure enough that we should never even know them to be such, to say nothing of conserving them as adequate conditions and material for thought. It is only by treating them as real facts in a real world, and only by carrying over into them, in some assumed and unexplained way, the capacity of representing the cosmic facts which cause them, that impressions or ideas come in any sense within the scope of thought. But if the antecedents are really impressions-in-their-objective-setting, then Lotze's whole way of distinguishing thought-worth from _mere_ existence or event without objective significance must be radically modified.
The implication that impressions have actually a quality or meaning of their own becomes explicit when we refer to Lotze's theory that the immediate antecedent of thought is found in the _matter_ of ideas. When thought is said to "take cognizance of _relations_ which its own activity does not originate, but which have been prepared for it by the unconscious mechanism of the psychic states,"[18] the attribution of objective content, of reference and meaning to ideas, is unambiguous. The idea forms a most convenient halfway house for Lotze. On one hand, as absolutely prior to thought, as material antecedent condition, it is merely psychical, bald subjective event. But as subject-matter for thought, as antecedent which affords stuff for thought's exercise, it characteristically qualifies content. Although we have been told that the impression is a mere receptive irritation without participation of mental activity, we are not surprised, in view of this capacity of ideas, to learn that the mind actually has a determining share in both the reception of stimuli and in their further associative combinations. The subject always enters into the presentation of any mental object, even the sensational, to say nothing of the perceptional and the imaged. The perception of a given state of things is possible only on the assumption that "the perceiving subject is at once enabled and compelled by its own nature to combine the excitations which reach it from objects into those forms which it is to perceive in the objects, and which it supposes itself simply to _receive_ from them."[19]
It is only by continual transition from impression and ideas as mental states and events to ideas as logical _objects or contents_, that Lotze bridges the gulf from bare exciting antecedent to concrete material conditions of thought. This contradiction, again, is necessary to Lotze's standpoint. To set out frankly with objects as antecedents would demand reconsideration of the whole viewpoint, which supposes that the difference between the logical and its antecedent is a matter of the difference between _worth_ and mere _existence_ or _occurrence_. It would indicate that since meaning or value is already there, the task of thought must be that of the transformation or _reconstruction of meaning_ through an intermediary process. On the other hand, to stick by the standpoint of _mere_ existence is not to get anything which can be called even antecedent of thought.
2. Why is there a task of transformation? Consideration of the material in its function of evoking thought, giving it its cue, will serve to complete the picture of the contradiction and of the real facts. It is the conflict between ideas as merely coincident and ideas as coherent which constitutes the need that provokes the response of thought. Here Lotze vibrates (_a_) between considering both coincidence and coherence as psychical events; (_b_) considering coincidence as purely psychical and coherence as at least quasi-logical, and (_c_) making them both determinations within the sphere of reflective thought. In strict accordance with his own premises, coincidence and coherence ought both to be mere peculiarities of the current of ideas as events within ourselves. But so taken the distinction becomes absolutely meaningless. Events do not cohere; at the most certain sets of them happen more or less frequently than other sets; the only intelligible difference is one of frequency of coincidence. And even this attributes to an event the supernatural trait of reappearing after it has disappeared. Even coincidence has to be defined in terms of relation of the _objects_ which are supposed to excite the psychical events that happen together.
As recent psychological discussion has made clear enough, it is the matter, meaning, or content of ideas that is associated, not the ideas as states or existences. Take such an idea as sun-revolving-about-earth. We may _say_ it means the conjunction of various sense impressions, but it is connection, or mutual reference, of _attributes_ that we have in mind in the assertion. It is absolutely certain that our psychical image of the sun is not psychically engaged in revolving about our psychical image of the earth. It would be amusing if such were the case; theaters and all dramatic representations would be at a discount. But in truth, sun-revolving-about-earth is a single meaning or intellectual object; it is a unified subject-matter within which certain distinctions of reference appear. It is concerned with what we intend when we think earth and sun, and think them in their relation to each other. It is a rule, specification, or direction of how to think when we have occasion to think a certain subject-matter. To treat this mutual reference as if it were simply a case of conjunction of mental events produced by psycho-physical irritation and association is a profound case of the psychological fallacy. We may, indeed, analyze an experience involving belief in an object of a certain kind and find that it had its origin in certain conditions of the sensitive organism, in certain peculiarities of perception and of association, and hence conclude that the belief involved in it was not justified by the facts themselves. But the significance of the belief in sun-revolving-about-earth by those who held it, consisted precisely in the fact that it was taken not as a mere association of feelings, but as a definite portion of the whole structure of objective experience, guaranteed by other parts of the fabric, and lending its support and giving its tone to them. It was to them part of the experienced frame of things--of the real world.
Put the other way, if such an instance meant a mere conjunction of psychical states, there would be in it absolutely nothing to evoke thought. Each idea as event, as Lotze himself points out (I, 2), may be regarded as adequately and necessarily determined to the place it occupies. There is absolutely no question on the side of events of mere coincidence _versus_ genuine connection. As event, it is there and it belongs there. We cannot treat something as at once a bare fact of existence and a problematic subject-matter of logical inquiry. To take the reflective point of view is to consider the matter in a totally new light; as Lotze says, it is to raise the question of rightful claims to a position or relation.
The point becomes clearer when we contrast coincidence with connection. To consider coincidence as simply psychical, and coherence as at least quasi-logical, is to put the two on such different bases that no question of contrasting them can arise. The coincidence which precedes a valid or grounded coherence (the conjunction which as coexistence of objects and sequence of acts is perfectly adequate) never is, as antecedent, the coincidence which is set over against coherence. The side-by-sideness of books on my bookshelf, the succession of noises that rise through my window, do not trouble me logically. They do not appear as errors or even as problems. One coexistence is just as good as any other until some new point of view, or new end, presents itself. If it is a question of the convenience of arrangement of books, then the value of their present collocation becomes a problem. Then I contrast their present state as bare conjunction over against another scheme as one which is coherent. If I regard the sequence of noises as a case of articulate speech, their order becomes important--it is a problem to be determined. The inquiry whether a given combination presents apparent or real connection shows that reflective inquiry is already going on. Does this phase of the moon really mean rain, or does it just happen that the rain-storm comes when the moon has reached this phase? To ask such questions shows that a certain portion of the universe of objective experience is subjected to critical analysis for purposes of definitive restatement. The tendency to regard some combination as mere coincidence is absolutely a _part_ of the movement of mind in its search for the real connection.
If coexistence as such is to be set against coherence as such, as the non-logical against the logical, then, since our whole spatial universe is one of collocation, and since thought in this universe can never get farther than substituting one collocation for another, the whole realm of space-experience is condemned offhand and in perpetuity to anti-rationality. But, in truth, coincidence as over against coherence, conjunction as over against connection, is just _suspected_ coherence, one which is under the fire of active inquiry. The distinction is one which arises only within the logical or reflective function. 3. This brings us explicitly to the fact that there is neither coincidence nor coherence in terms of the elements or meanings contained in any couple or pair of ideas taken by itself. It is only when they are co-factors in a situation or function which includes more than either the "coincident" or the "coherent" and more than the arithmetical sum of the two, that thought's activity can be evoked. Lotze is continually in this dilemma: Thought either shapes its own material or else just accepts it. In the first case (since Lotze cannot rid himself of the presumption that thought must have a fixed ready-made antecedent) its activity can only alter this stuff and thus lead the mind farther away from reality. But if thought just accepts its material, how can there be any distinctive aim or activity of thought at all? As we have seen, Lotze endeavors to escape this dilemma by supposing that, while thought receives its material yet checks it up, it eliminates certain portions of it and reinstates others, plus the stamp and seal of its own validity.
