The simple fact is that in such illustrations as "blue," "franchise," "conjunction," Lotze instinctively takes cases which are not mere independent and detached meanings, but which involve reference to a region of cosmic experience, or to a region of mutually determining social activities. The conception that reference to a social activity does not involve the same sort of reference of thought beyond itself that is involved in physical matters, and hence may be taken quite innocent and free of the metaphysical problem of reference to reality beyond meaning, is one of the strangest that has ever found lodgment in human thinking. Either both physical and social reference or neither, is metaphysical; if neither, then it is because the meaning functions, as it originates, in a specific situation which carries with it its own tests (see p. 17). Lotze's conception is made possible only by unconsciously substituting the idea of object as content of thought for a large number of persons (or a de facto somewhat for every consciousness), for the genuine definition of object as a determinant in a scheme of experience. The former is consistent with Lotze's conception of thought, but wholly indeterminate as to validity or intent. The latter is the test used experimentally in all concrete thinking, but involves a radical transformation of all Lotze's assumptions. A given idea of the conjunction of the franchise, or of blue, is valid, not because everybody happens to entertain it, but because it expresses the factor of control or direction in a given movement of experience. The test of validity of idea[39] is its functional or instrumental use in effecting the transition from a relatively conflicting experience to a relatively integrated one. If Lotze's view were correct, "blue" valid once would be valid always—even when red or green were actually called for to fulfil specific conditions. This is to say validity always refers to rightfulness or adequacy of performance in an asserting of connection—not to the meaning as detached and contemplated.

If we refer again to the fact that the genuine antecedent of thought is a situation which is tensional as regards its existing status, or disorganized in its structural elements, yet organized as emerging out of the unified experience of the past and as striving as a whole, or equally in all its phases, to reinstate an experience harmonized in make-up, we can easily understand how certain contents may be detached and held apart as meanings or references, actual or possible (according as they are viewed with reference to the past or to the future). We can understand how such detached contents may be of use in effecting a review of the entire experience, and as affording standpoints and methods of a reconstruction which will maintain the integrity of experience. We can understand how validity of meaning is measured by reference to something which is not mere meaning; by reference to something which lies beyond the idea as such—viz., the reconstitution of an experience into which thought enters as mediator. That paradox of ordinary experience and of scientific inquiry by which objectivity is given alike to matter of perception and to conceived relations—to facts and to laws—affords no peculiar difficulty, because we see that the test of objectivity is everywhere the same: anything is objective in so far as, through the medium of conflict, it controls the movement of experience in its reconstructive transition from one unified form to another. There is not first an object, whether of sense-perception or of conception, which afterward somehow exercises this controlling influence; but the objective is such in virtue of the exercise of function of control. It may only control the act of inquiry; it may only set on foot doubt, but this is direction of subsequent experience, and, in so far, is a token of objectivity.

So much for the thought-content or meaning as having a validity of its own. It does not have it as isolated or given or static; it has it in its dynamic reference, its use in determining further movement of experience. In other words, the "meaning" or idea as such, having been selected and made-up with reference to performing a certain office in the evolution of a unified experience, can be tested in no other way than by discovering whether it does what it was intended to do and what it purports to do.[40]

2. Lotze has to wrestle with this question of validity in a further aspect: What constitutes the objectivity of thinking as a total attitude, activity, or function? According to his own statement, the meanings or valid ideas are after all only building-stones for logical thought. Validity is thus not a question of them in their independent existences, but of their mutual reference to each other. Thinking is the process of instituting these mutual references; of building up the various scattered and independent building-stones into the coherent system of thought. What is the validity of the various forms of thinking which find expression in the various types of judgment and in the various forms of inference? Categorical, hypothetical, disjunctive judgment; inference by induction, by analogy, by mathematical equation; classification, theory of explanation—all these are processes of reflection by which mutual connection in an individualized whole is given to the fragmentary meanings or ideas with which thought as it sets out is supplied. What shall we say of the validity of such processes?

On one point Lotze is quite clear. These various logical acts do not really enter into the constitution of the valid world. The logical forms as such are maintained only in the process of thinking. The world of valid truth does not undergo a series of contortions and evolutions, paralleling in any way the successive steps and missteps, the succession of tentative trials, withdrawals, and retracings, which mark the course of our own thinking.[41]

Lotze is explicit upon the point that it is only the thought-content in which the process of thinking issues that has objective validity; the act of thinking is "purely and simply an inner movement of our own minds, made necessary to us by reason of the constitution of our nature and of our place in the world" (Vol. II, p. 279).

Here the problem of validity presents itself as the problem of the relation of the act of thinking to its own product. In his solution Lotze uses two metaphors: one derived from building operations, the other from traveling. The construction of a building requires of necessity certain tools and extraneous constructions, stagings, scaffoldings, etc., which are necessary to effect the final construction, but yet which do not enter into the building as such. The activity has an instrumental, though not a constitutive, value as regards its product. Similarly, in order to get a view from the top of a mountain—this view being the objective—the traveler has to go through preliminary movements along devious courses. These again are antecedent prerequisites, but do not constitute a portion of the attained view.

The problem of thought as activity, as distinct from thought as content, opens up altogether too large a question to receive complete consideration at this point. Fortunately, however, the previous discussion enables us to narrow the point which is in issue just here. It is once more the question whether the activity of thought is to be regarded as an independent function supervening entirely from without upon antecedents, and directed from without upon data; or whether it marks merely a phase of the transformation which the course of experience (whether practical, or artistic, or socially affectional or whatever) undergoes in entering into a tensional status where the maintenance of its harmony of content is problematic and hence an aim. If it be the latter, a thoroughly intelligent sense can be given to the proposition that the activity of thinking is instrumental, and that its worth is found, not in its own successive states as such, but in the result in which it comes to conclusion. But the conception of thinking as an independent activity somehow occurring after an independent antecedent, playing upon an independent subject-matter, and finally effecting an independent result, presents us with just one miracle the more.

I do not question the strictly instrumental character of thinking. The problem lies not here, but in the interpretation of the nature of the organ and instrument. The difficulty with Lotze's position is that it forces us into the assumption of a means and an end which are simply and only external to each other, and yet necessarily dependent upon each other—a position which, whenever found, is so thoroughly self-contradictory as to necessitate critical reconsideration of the premises which lead to it. Lotze vibrates between the notion of thought as a tool in the external sense, a mere scaffolding to a finished building in which it has no part nor lot, and the notion of thought as an immanent tool, as a scaffolding which is an integral part of the very operation of building, and set up for the sake of the building-activity which is carried on effectively only with and through a scaffolding. Only in the former case can the scaffolding be considered as a mere tool. In the latter case the external scaffolding is not itself the instrumentality; the actual tool is the action of erecting the building, and this action involves the scaffolding as a constituent part of itself. The work of erecting is not set over against the completed building as mere means to an end; it is the end taken in process or historically, longitudinally viewed. The scaffolding, moreover, is not an external means to the process of erecting, but an organic member of it. It is no mere accident of language that "building" has a double sense—meaning at once the process and the finished product. The outcome of thought is the thinking activity carried on to its own completion; the activity, on the other hand, is the outcome taken anywhere short of its own realization, and thereby still going on.

The only consideration which prevents easy and immediate acceptance of this view is the notion of thinking as something purely formal. It is strange that the empiricist does not see that his insistence upon a matter extraneously given to thought only strengthens the hands of the rationalist with his claim of thinking as an independent activity, separate from the actual make-up of the affairs of experience. Thinking as a merely formal activity exercised upon certain sensations or images or objects sets forth an absolutely meaningless proposition. The psychological identification of thinking with the process of association is much nearer the truth. It is, indeed, on the way to the truth. We need only to recognize that association is of contents or matters or meanings, not of ideas as bare existences or events; and that the type of association we call thinking differs from the associations of casual fancy and revery in an element of control by reference to an end which determines the fitness and thus the selection of the associates, to apprehend how completely thinking is a reconstructive movement of actual contents of experience in relation to each other, and for the sake of a redintegration of a conflicting experience.

There is no miracle in the fact that tool and material are adapted to each other in the process of reaching a valid conclusion. Were they external in origin to each other and to the result, the whole affair would, indeed, present an insoluble problem—so insoluble that, if this were the true condition of affairs, we never should even know that there was a problem. But, in truth, both material and tool have been secured and determined with reference to economy and efficiency in effecting the end desired—the maintenance of a harmonious experience. The builder has discovered that his building means building tools, and also building material. Each has been slowly evolved with reference to its fit employ in the entire function; and this evolution has been checked at every point by reference to its own correspondent. The carpenter has not thought at large on his building and then constructed tools at large, but has thought of his building in terms of the material which enters into it, and through that medium has come to the consideration of the tools which are helpful. Life proposes to maintain at all hazards the unity of its own process. Experience insists on being itself, on securing integrity even through and by means of conflict.

This is not a formal question, but one of the placing and relations of the matters or values actually entering into experience. And this in turn determines the taking up of just those mental attitudes, and the employing of just those intellectual operations, which most effectively handle and organize the material. Thinking is adaptation to an end through the adjustment of particular objective contents.

The thinker, like the carpenter, is at once stimulated and checked in every stage of his procedure by the particular situation which confronts him. A person is at the stage of wanting a new house: well then, his materials are available resources, the price of labor, the cost of building, the state and needs of his family, profession, etc.; his tools are paper and pencil and compass, or possibly the bank as a credit instrumentality, etc. Again, the work is beginning. The foundations are laid. This in turn determines its own specific materials and tools. Again, the building is almost ready for occupancy. The concrete process is that of taking away the scaffolding, clearing up the grounds, furnishing and decorating rooms, etc. This specific operation again determines its own fit or relevant materials and tools. It defines the time and mode and manner of beginning and ceasing to use them. Logical theory will get along as well as does reflective practice, when it sticks close by and observes the directions and checks inherent in each successive phase of the evolution of the cycle of experiencing. The problem in general of validity of the thinking process as distinct from the validity of this or that process arises only when thinking is isolated from its historic position and its material context.

3. But Lotze is not yet done with the problem of validity, even from his own standpoint. The ground shifts again under his feet. It is no longer a question of the validity of the idea or meaning with which thought is supposed to set out; it is no longer a question of the validity of the process of thinking in reference to its own product; it is the question of the validity of the product. Supposing, after all, that the final meaning, or logical idea, is thoroughly coherent and organized; supposing it is an object for all consciousness as such. Once more arises the question: What is the validity of even the most coherent and complete idea?—a question which rises and will not down. We may reconstruct our notion of the chimera until it ceases to be an independent idea and becomes a part of the system of Greek mythology. Has it gained in validity in ceasing to be an independent myth, in becoming an element in systematized myth? Myth it was and myth it remains. Mythology does not get validity by growing bigger. How do we know the same is not the case with the ideas which are the product of our most deliberate and extended scientific inquiry? The reference again to the content as the self-identical object of all consciousness proves nothing; the matter of a hallucination does not gain worth in proportion to its social contagiousness. Or the reference proves that we have not as yet reached any conclusion, but are entertaining a hypothesis—since social validity is not a matter of mere common content, but of securing participation in a commonly adjudged social experience through action directed thereto and directed by consensus of judgment.

According to Lotze, the final product is, after all, still thought. Now, Lotze is committed once for all to the notion that thought, in any form, is directed by and at an outside reality. The ghost haunts him to the last. How, after all, does even the ideally perfect valid thought apply or refer to reality? Its genuine subject is still beyond itself. At the last Lotze can dispose of this question only by regarding it as a metaphysical, not a logical, problem (Vol. II, pp. 281, 282). In other words, logically speaking, we are at the end just exactly where we were at the beginning—in the sphere of ideas, and of ideas only, plus a consciousness of the necessity of referring these ideas to a reality which is beyond them, which is utterly inaccessible to them, which is out of reach of any influence which they may exercise, and which transcends any possible comparison with their results. "It is vain," says Lotze, "to shrink from acknowledging the circle here involved ... all we know of the external world depends upon the ideas of it which are within us" (Vol. II, p. 185). "It is then this varied world of ideas within us which forms the sole material directly given to us" (Vol. II, p. 186). As it is the only material given to us, so it is the only material with which thought can end. To talk about knowing the external world through ideas which are merely within us is to talk of an inherent self-contradiction. There is no common ground in which the external world and our ideas can meet. In other words, the original implication of a separation between an independent thought-material and an independent thought-function and purpose lands us inevitably in the metaphysics of subjective idealism, plus a belief in an unknown reality beyond, which unknowable is yet taken as the ultimate test of the value of our ideas as just subjective. The subjectivity of the psychical event infects at the last the meaning or ideal object. Because it has been taken to be something "in itself," thought is also something "in itself," and at the end, after all our maneuvering we are where we began:—with two separate disparates, one of meaning, but no existence, the other of existence, but no meaning.

The other aspect of Lotze's contradiction which completes the circle is clear when we refer to his original propositions, and recall that at the outset he was compelled to regard the origination and conjunctions of the impressions, the elements of ideas, as themselves the effects exercised by a world of things already in existence (see p. 31). He sets up an independent world of thought, and yet has to confess that both at its origin and termination it points with absolute necessity to a world beyond itself. Only the stubborn refusal to take this initial and terminal reference of thought beyond itself as having a historic meaning, indicating a particular place of generation and a particular point of fulfilment in the drama of evolving experience, compels Lotze to give such bifold objective reference a purely metaphysical turn.

When Lotze goes on to say (Vol. II, p. 191) that the measure of truth of particular parts of experience is found in asking whether, when judged by thought, they are in harmony with other parts of experience; when he goes on to say that there is no sense in trying to compare the entire world of ideas with a reality which is non-existent, excepting as it itself should become an idea, Lotze lands where he might better have frankly commenced.[43] He saves himself from utter skepticism only by claiming that the explicit assumption of skepticism, the need of agreement of a ready-made idea as such, with an extraneous independent material as such, is meaningless. He defines correctly the work of thought as consisting in harmonizing the various portions of experience with each other: a definition which has meaning only in connection with the fact that experience is continually integrating itself into a wholeness of coherent meaning deepened in significance by passing through an inner distraction in which by means of conflict certain contents are rendered partial and hence objectively conscious. In this case the test of thought is the harmony or unity of experience actually effected. In that sense the test of reality is beyond thought, as thought, just as at the other limit thought originates out of a situation which is not reflectional in character. Interpret this before and beyond in a historic sense, as an affair of the place occupied and rôle played by thinking as a function in experience in relation to other functions, and the intermediate and instrumental character of thought, its dependence upon unreflective antecedents for its existence, and upon a consequent experience for its test of final validity, becomes significant and necessary. Taken at large, it plunges us in the depths of a hopelessly complicated and self-revolving metaphysic.
