Neither the plain man nor the scientific inquirer is aware, as he engages in his reflective activity, of any transition from one sphere of existence to another. He knows no two fixed worlds--reality on one side and mere subjective ideas on the other; he is aware of no gulf to cross. He a.s.sumes uninterrupted, free, and fluid pa.s.sage from ordinary experience to abstract thinking, from thought to fact, from things to theories and back again. Observation pa.s.ses into development of hypothesis; deductive methods pa.s.s into use in description of the particular; inference pa.s.ses into action, all with no sense of difficulty save those found in the particular task in question. The fundamental a.s.sumption is _continuity_.
This does not mean that fact is confused with idea, or observed datum with voluntary hypothesis, theory with doing, any more than a traveler confuses land and water when he journeys from one to the other. It simply means that each is placed and used with reference to service rendered the other, and with reference to the future use of the other.
Only the epistemological spectator of traditional controversies is aware of the fact that the everyday man and the scientific man in this free and easy intercourse are rashly a.s.suming the right to glide over a cleft in the very structure of reality. This fact raises a query not favorable to the epistemologist. Why is it that the scientific man, who is constantly plying his venturous traffic of exchange of facts for ideas, of theories for laws, of real things for hypotheses, should be so wholly unaware of the radical and generic (as distinct from specific) difficulty of the undertakings in which he is engaged? We thus come afresh to our inquiry: Does not the epistemological logician unwittingly transfer the specific difficulty which always faces the scientific man--the difficulty in detail of correct and adequate translation back and forth of _this_ set of facts and _this_ group of reflective consideration--into a totally different problem of the wholesale relation of thought at large to reality in general? If such be the case, it is clear that the very way in which the epistemological type of logic states the problem of thinking, in relation both to empirical antecedents and to objective truth, makes that problem insoluble. Working terms, terms which as working are flexible and historic, relative and methodological, are transformed into absolute, fixed, and predetermined properties of being.
We come a little closer to the problem when we recognize that every scientific inquiry pa.s.ses historically through at least four stages.
(_a_) The first of these stages is, if I may be allowed the bull, that in which scientific inquiry does not take place at all, because no problem or difficulty in the quality of the experience presents itself to provoke reflection. We have only to cast our eye back from the existing status of any science, or back from the status of any particular topic in any science, to discover a time when no reflective or critical thinking busied itself with the matter--when the facts and relations were taken for granted and thus were lost and absorbed in the net meaning which accrued from the experience. (_b_) After the dawning of the problem there comes a period of occupation with relatively crude and unorganized facts--hunting for, locating, and collecting raw material. This is the empiric stage, which no existing science, however proud in its attained rationality, can disavow as its own progenitor. (_c_) Then there is also a speculative stage: a period of guessing, of making hypotheses, of framing ideas which later on are labeled and condemned as only ideas. There is a period of distinction-making and cla.s.sification-making which later on is regarded as only mentally gymnastic in character. And no science, however proud in its present security of experimental a.s.surance, can disavow a scholastic ancestor. (_d_) Finally, there comes a period of fruitful interaction between the mere ideas and the mere facts: a period when observation is determined by experimental conditions depending upon the use of certain guiding conceptions; when reflection is directed and checked at every point by the use of experimental data, and by the necessity of finding such a form for itself as will enable it to serve in a deduction leading to evolution of new meanings, and ultimately to experimental inquiry which brings to light new facts. In the emerging of a more orderly and significant region of fact, and of a more coherent and self-luminous system of meaning, we have the natural limit of evolution of the logic of a given science.
But consider what has happened in this historic record. Una.n.a.lyzed experience has broken up into distinctions of facts and ideas; the factual side has been developed by indefinite and almost miscellaneous descriptions and c.u.mulative listings; the conceptual side has been developed by unchecked and speculative elaboration of definitions, cla.s.sifications, etc. Then there has been a relegation of accepted meanings to the limbo of mere ideas; there has been a pa.s.sage of some of the accepted facts into the region of mere hypothesis and opinion.
Conversely, there has been a continued issuing of ideas from the region of hypotheses and theories into that of facts, of accepted objective and meaningful objects. Out of a world of only _seeming_ facts, and of only _doubtful_ ideas, there emerges a world continually growing in definiteness, order, and luminosity.
This progress, verified in every record of science, is an absolute monstrosity from the standpoint of the epistemology which a.s.sumes a thought in general, on one side, and a reality in general, on the other. The reason that it does not present itself as such a monster and miracle to those actually concerned with it is because _continuity_ of reference and of use controls all diversities in the modes of existence specified and the types of significance a.s.signed.
The distinction of meaning and fact is treated in the growth of a science, or of any particular scientific problem, as an _induced_ and _intentional_ practical division of labor; as a.s.signments of relative position with reference to performance of a task; as deliberate distribution of forces at command for their more economic use. The absorption of bald fact and hypothetical idea into the formation of a single world of scientific apprehension and comprehension is but the successful achieving of the aim on account of which the distinctions in question were inst.i.tuted.
Thus we come back to the problem of logical theory. To take the distinctions of thought and fact, etc., as ontological, as inherently fixed in the makeup of the structure of being, results in treating the actual technique of scientific inquiry and scientific control as a mere subsidiary topic--ultimately of only utilitarian worth. It also states the terms upon which thought and being transact business in a way so totally alien to concrete experience that it creates a problem which can be discussed only in terms of itself--not in terms of the conduct of life. As against this, the logic which aligns itself with the origin and employ of reflective thought in everyday life and critical science follows the natural history of thinking as a life-process having its own generating antecedents and stimuli, its own states and career, and its own specific objective or limit.
This point of view makes it possible for logical theory to come to terms with psychology. When logic is considered as having to do with the wholesale activity of thought _per se_, the question of the historic process by which this or that particular thought came to be, of how its object happens to present itself as sensory, or perceptual, or conceptual, is quite irrelevant. These things are mere temporal accidents. The psychologist (not lifting his gaze from the realm of the changeable) may find in them matters of interest. His whole industry is just with natural history--to trace events as they mutually excite and inhibit one another. But the logician, we are told, has a deeper problem and an outlook of more unbounded horizon.
He deals with the question of the eternal nature of thought and its eternal validity in relation to an eternal reality. He is concerned, not with genesis, but with value, not with a historic cycle, but with absolute ent.i.ties and relations.
Still the query haunts us: Is this so in truth? Or has the logician of a certain type arbitrarily made it so by taking his terms apart from reference to the specific occasions in which they arise and situations in which they function? If the latter, then the very denial of historic relationship, the denial of the significance of historic method, is indicative of the unreal character of his own abstraction.
It means in effect that the affairs under consideration have been isolated from the conditions in which alone they have determinable meaning and a.s.signable worth. It is astonishing that, in the face of the advance of the evolutionary method in natural science, any logician can persist in the a.s.sertion of a rigid difference between the problem of origin and of nature; between genesis and a.n.a.lysis; between history and validity. Such a.s.sertion simply reiterates as final a distinction which grew up and had meaning in pre-evolutionary science. It a.s.serts, against the most marked advance which scientific method has yet made, a survival of a crude period of logical scientific procedure. We have no choice save either to conceive of thinking as a response to a specific stimulus, or else to regard it as something "in itself," having just in and of itself certain traits, elements, and laws. If we give up the last view, we must take the former. In this case it will still possess distinctive traits, but they will be traits of a specific response to a specific stimulus.
The significance of the evolutionary method in biology and social history is that every distinct organ, structure, or formation, every grouping of cells or elements, is to be treated as an instrument of adjustment or adaptation to a particular environing situation. Its meaning, its character, its force, is known when, and only when, it is considered as an arrangement for meeting the conditions involved in some specific situation. This a.n.a.lysis is carried out by tracing successive stages of development--by endeavoring to locate the particular situation in which each structure has its origin, and by tracing the successive modifications through which, in response to changing media, it has reached its present conformation.[12] To persist in condemning natural history from the standpoint of what natural history meant before it identified itself with an evolutionary process is not so much to exclude the natural-history standpoint from philosophic consideration as it is to evince ignorance of what it signifies.
Psychology as the natural history of the various att.i.tudes and structures through which experiencing pa.s.ses, as an account of the conditions under which this or that att.i.tude emerges, and of the way in which it influences, by stimulation or inhibition, production of other states or conformations of reflection, is indispensable to logical evaluation the moment we treat logical theory as an account of thinking as a response to its own generating conditions, and consequently judge its validity by reference to its efficiency in meeting its problems. The historical point of view describes the sequence; the normative follows the history to its conclusion, and then turns back and judges each historical step by viewing it in reference to its own outcome.
In the course of changing experience we keep our balance in moving from situations of an affectional quality to those which are practical or appreciative or reflective, because we bear constantly in mind the context in which any particular distinction presents itself.
As we submit each characteristic function and situation of experience to our gaze, we find it has a dual aspect. Wherever there is striving there are obstacles; wherever there is affection there are persons who are attached; wherever there is doing there is accomplishment; wherever there is appreciation there is value; wherever there is thinking there is material-in-question. We keep our footing as we move from one att.i.tude to another, from one characteristic quality to another, because of the position occupied in the whole movement by the particular function in which we are engaged.
The distinction _between_ each att.i.tude and function and its predecessor and successor is serial, dynamic, operative. The distinctions _within_ any given operation or function are structural, contemporaneous, and distributive. Thinking follows, we will say, striving, and doing follows thinking. Each in the fulfilment of its own function inevitably calls out its successor. But coincident, simultaneous, and correspondent _within_ doing is the distinction of doer and of deed; _within_ the function of thought, of thinking and material thought upon; within the function of striving, of obstacle and aim, of means and end. We keep our paths straight because we do not confuse the sequential and functional relationship of types of experience with the contemporaneous and structural distinctions of elements within a given function. In the seeming maze of endless confusion and unlimited shiftings, we find our way by the means of the stimulations and checks occurring within the process in which we are actually engaged. Operating within empirical situations we do not contrast or confuse a condition which is an element in the formation of one operation with the status which is one of the distributive terms of another function. When we ignore these specific empirical clues and limitations, we have at once an insoluble, because meaningless, problem upon our hands.
Now the epistemological logician deliberately shuts himself off from those cues and checks upon which the plain man instinctively relies, and which the scientific man deliberately searches for and adopts as const.i.tuting his technique. Consequently he is likely to set the att.i.tude which has place and significance only in one of the serial functional situations of experience over against the active att.i.tude which describes part of the structural const.i.tution of another situation; or with equal lack of justification to a.s.similate materials characteristic of different stages to one another. He sets the agent, as he is found in the intimacy of love or appreciation, over against the externality of the fact, as that is defined within the reflective process. He takes the material which thought selects as its problematic data as identical with the significant content which results from successful pursuit of inquiry; and this in turn he regards as the material which was presented before thinking began, whose peculiarities were the means of awakening thought. He identifies the final deposit of the thought-function with its own generating antecedent, and then disposes of the resulting surd by reference to some metaphysical consideration, which remains when logical inquiry, when science (as interpreted by him), has done its work. He does this, not because he prefers confusion to order, or error to truth, but simply because, when the chain of historic sequence is cut, the vessel of thought is afloat to veer upon a sea without soundings or moorings.
There are but two alternatives: either there is an object "in itself"
of mind "in itself," or else there are a series of situations where elements vary with the varying functions to which they belong. If the latter, the only way in which the characteristic terms of situations can be defined is by discriminating the functions to which they belong. And the epistemological logician, in choosing to take his question as one of thought which has its own form just as "thought,"
apart from the limits of the special work it has to do, has deprived himself of these supports and stays.
The problem of logic has a more general and a more specific phase. In its generic form, it deals with this question: How does one type of functional situation and att.i.tude in experience pa.s.s out of and into another; for example, the technological or utilitarian into the aesthetic, the aesthetic into the religious, the religious into the scientific, and this into the socio-ethical and so on? The more specific question is: How does the particular functional situation termed the reflective behave? How shall we describe it? What in detail are its diverse contemporaneous distinctions, or divisions of labor, its correspondent _statuses_; in what specific ways do these operate with reference to each other so as to effect the specific aim which is proposed by the needs of the affair?
This chapter may be brought to conclusion by reference to the more ultimate value of the logic of experience, of logic taken in its wider sense; that is, as an account of the sequence of the various typical functions or situations of experience in their determining relations to one another. Philosophy, defined as such a logic, makes no pretense to be an account of a closed and finished universe. Its business is not to secure or guarantee any particular reality or value. _Per contra_, it gets the significance of a method. The right relationship and adjustment of the various typical phases of experience to one another is a problem felt in every department of life. Intellectual rectification and control of these adjustments cannot fail to reflect itself in an added clearness and security on the practical side. It may be that general logic cannot become an instrument in the immediate direction of the activities of science or art or industry; but it is of value in criticizing and organizing tools of immediate research.
It also has direct significance in the valuation for social or life-purposes of results achieved in particular branches. Much of the immediate business of life is badly done because we do not know the genesis and outcome of the work that occupies us. The manner and degree of appropriation of the goods achieved in various departments of social interest and vocation are partial and faulty because we are not clear as to the due rights and responsibilities of one function of experience in reference to others.
The value of research for social progress; the bearing of psychology upon educational procedure; the mutual relations of fine and industrial art; the question of the extent and nature of specialization in science in comparison with the claims of applied science; the adjustment of religious aspirations to scientific statements; the justification of a refined culture for a few in face of economic insufficiency for the ma.s.s; the relation of organization to individuality--such are a few of the many social questions whose answer depends upon the possession and use of a general logic of experience as a method of inquiry and interpretation. I do not say that headway cannot be made in such questions apart from the method indicated: a logic of experience. But unless we have a critical and a.s.sured view of the juncture in which and with reference to which a given att.i.tude or interest arises, unless we know the service it is thereby called upon to perform, and hence the organs or methods by which it best functions in that service, our progress is impeded and irregular. We take a part for a whole, a means for an end; or we attack wholesale some interest because it interferes with the deified sway of the one we have selected as ultimate. A clear and comprehensive consensus of social conviction and a consequent concentrated and economical direction of effort are a.s.sured only as there is some way of locating the position and role of each typical interest and occupation. The domain of opinion is one of conflict; its rule is arbitrary and costly. Only intellectual method affords a subst.i.tute for opinion. A general logic of experience alone can do for social qualities and aims what the natural sciences after centuries of struggle are doing for activity in the physical realm.
This does not mean that systems of philosophy which have attempted to state the nature of thought and of reality at large, apart from limits of particular situations in the movement of experience, have been worthless--though it does mean that their industry has been somewhat misapplied. The unfolding of metaphysical theory has made large contributions to positive evaluations of the typical situations and relationships of experience--even when its conscious intention has been quite otherwise. Every system of philosophy is itself a mode of reflection; consequently (if our main contention be true), it too has been evoked out of specific social antecedents, and has had its use as a response to them. It has effected something in modifying the situation within which it found its origin. It may not have solved the problem which it consciously put itself; in many cases we may freely admit that the question put has been found afterward to be so wrongly put as to be insoluble. Yet exactly the same thing is true, in precisely the same sense, in the history of science. For this reason, if for no other, it is impossible for the scientific man to cast the first stone at the philosopher.
The progress of science in any branch continually brings with it a realization that problems in their previous form of statement are insoluble because put in terms of unreal conditions; because the real conditions have been mixed up with mental artifacts or misconstructions. Every science is continually learning that its supposed solutions are only apparent because the "solution" solves, not the actual problem, but one which has been made up. But the very putting of the question, the very giving of the wrong answer, induces modification of existing intellectual habits, standpoints, and aims.
Wrestling with the problem, there is evolution of new technique to control inquiry, there is search for new facts, inst.i.tution of new types of experimentation; there is gain in the methodic control of experience. And all this is progress. It is only the worn-out cynic, the de-vitalized sensualist, and the fanatical dogmatist who interpret the continuous change of science as proving that, since each successive statement is wrong, the whole record is error and folly; and that the present truth is only the error not yet found out. Such draw the moral of caring naught for all these things, or of flying to some external authority which will deliver once for all the fixed and unchangeable truth. But historic philosophy even in its aberrant forms has proved a factor in the valuation of experience; it has brought problems to light, it has provoked intellectual conflicts without which values are only nominal; even through its would-be absolutistic isolations it has secured recognition of mutual dependencies and reciprocal reinforcements. Yet if it can define its work more clearly, it can concentrate its energy upon its own characteristic problem: the genesis and functioning in experience of various typical interests and occupations with reference to one another.

THE ANTECEDENTS AND STIMULI OF THINKING
We have discriminated logic in its wider sense--concerned with the sequence of characteristic functions and att.i.tudes 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 a.n.a.lytic, as distinct from a merely vague and gross, view of what we mean by reflection--what is its actual const.i.tution. 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 a.s.sumes 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 pa.s.sing 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 a.s.sumptions; 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 antic.i.p.ation 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 att.i.tude toward that fact--the att.i.tude 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 a.s.sumptions 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 a.s.sign 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 a.s.sociative 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 a.s.sociative 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 a.s.sociative 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 a.s.sociative 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 a.s.sumes 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 a.s.sociation 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 a.n.a.lysis 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 pa.s.sive 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 const.i.tution and organization of the whole world of ideas, a const.i.tution which, though not necessary in thought, is all the more necessary to make thinking possible."[17]
The impressions and ideas thus play a versatile role; they now a.s.sume the part of ultimate antecedents and provocative conditions; of crude material; and somehow, when arranged, of content for thought. This very versatility awakens suspicion.
