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 in particular with description and interpretation of 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 historic position of reflection in the evolving 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 apparent confusion of existing logical theory, its uncertainty as to its own bounds and limits, its tendency to oscillate from larger questions of the inherent worth of judgment and validity of inference over to details of scientific technique, and to translation of distinctions of formal logic into terms of 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, so far as such locus enables us to select and 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 transformation of experience; and that continual confusion and inconsistency are introduced when these respective meanings are not identified and described according to their respective geneses and places. I shall attempt to show that we must consider subject-matter from the standpoint, first, of the antecedents or conditions that evoke thought; second, of the datum or immediate material presented to thought; and, third, of the proper content 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; the material which is organized into the thought-situation, so far as this has fulfilled its purpose. It goes without saying that these are to be discriminated as stages of a life-process in the natural history of experience, not as ready-made or ontological; it is contended that, save as they are differentiated in connection with well-defined historical stages, they are either lumped off as equivalents, or else treated as absolute divisions—or as each by turns, according to the exigencies of the particular argument. In fact, 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 of experience, and therefore endeavoring to interpret certain notions as absolute instead of as periodic 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 re-testing and criticising of the intellectual standpoints and methods which we bring with us to the study.

Everyone comes with certain distinctions already made between the subjective and the objective, between the physical and the psychical, between the intellectual and the factual. (1) We have learned to regard the region of emotional disturbance, of uncertainty and aspiration, as belonging somehow peculiarly to ourselves; we have learned to set over against this a 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 of sense-perception; the given with the ideal. (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 constructs, our mental habits are so set that they tend to have their own way with us; and 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.

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 it stuff upon which to 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 his discussion is successful; if Lotze can provide the intermediaries which span the gulf between an independent thought-material and an independent thought-activity; if he can show that the question of the origin of thought-material and of thought-activity is irrelevant to the question of its worth, we shall have to surrender the position already taken. But if we find that Lotze's elaborations only elaborate the same fundamental difficulty, presenting it now in this light and now in that, but never effecting more than 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 matter of fact, falls back upon some organized situation or function as the source of both the specific thought-material and the specific thought-activity in correspondence with each other, we shall have in so far an elucidation and even a corroboration of our theory.

1. 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 it its cue. Lotze differs from many logicians of the same type in affording us an explicit account of these antecedents. 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."[5]

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. It is this distinction which marks off thought as activity from any psychical event and from the associative mechanism as receptive happenings. One is concerned with mere de facto coexistences and sequences; the other with the worth of these combinations.[6]

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."[7] And again:[8] "Thought can make no difference where it finds none already in the matter of the impressions." And again:[9] "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."

The impressions and ideas 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 the 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 arouse 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 matter or 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,"[10] the attribution of objective content, of reference and meaning to ideas, is unambiguous. The idea forms a most convenient half-way house for Lotze. On one hand, as absolutely prior to thought, as material antecedent condition, it is merely psychical, a bald subjective event. But as subject-matter for thought, as antecedent which affords stuff for thought's exercise, it is meaning, characteristic quality of 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."[11]

It is only by continual transition from impression and ideas as mental states and events to ideas as cognitive (or 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 "meanings" as antecedents would demand reconsideration of the whole view-point, 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 worth through an intermediary process of valuation. 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 that constitutes the need which provokes the response of thought. Here Lotze vibrates (a) between considering coincidence and coherence as both affairs of existence of psychical events; (b) considering coincidence as purely psychical and coherence as at least quasi-logical, and (c) the inherent logic which makes them both determinations within the sphere of reflective thought. In strict accordance with his own premises, coincidence and coherence both ought 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 repetition 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 conjunction, 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. In truth, sun-revolving-about-earth is a single meaning or idea; 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 really a specification or direction of how to think when we have occasion to think a certain subject-matter. To treat the origin of this mutual reference as if it were simply a case of conjunction of ideas produced by conditions of original psycho-physical irritation and association is a profound case of the psychological fallacy. We may, indeed, analyze an experience 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 as an item of the experience of those who meant 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 experience-frame of things—of the real universe.
