The question of how the possibility of meanings, or thought-contents, is to be understood merges imperceptibly into the question of the real objectivity or validity of such contents. The difficulty for Lotze is the now familiar one: So far as his logic compels him to insist that these meanings are the possession and product of thought (since thought is an independent activity), the ideas are merely ideas; there is no test of objectivity beyond the thoroughly unsatisfactory and formal one of their own mutual consistency. In reaction from this Lotze is thrown back upon the idea of these contents as the original matter given in the impressions themselves. Here there seems to be an objective or external test by which the reality of thought's operations may be tried; a given idea is verified or found false according to its measure of correspondence with the matter of experience as such. But now we are no better off. The original independence and heterogeneity of impressions and of thought is so great that there is no way to compare the results of the latter with the former. We cannot compare or contrast distinctions of worth with bare differences of factual existence (Vol. I, p. 2). The standard or test of objectivity is so thoroughly external that by original definition it is wholly outside the realm of thought. How can thought compare its own contents with that which is wholly outside itself?
Or again, the given material of experience apart from thought is precisely the relatively chaotic and unorganized; it even reduces itself to a mere sequence of psychical events. What rational meaning is there in directing us to compare the highest results of scientific inquiry with the bare sequence of our own states of feeling; or even with the original data whose fragmentary and uncertain character was the exact motive for entering upon scientific inquiry? How can the former in any sense give a check or test of the value of the latter? This is professedly to test the validity of a system of meanings by comparison with that whose defects and errors call forth the construction of the system of meanings by which to rectify and replace themselves. Our subsequent inquiry simply consists in tracing some of the phases of the characteristic seesaw from one to the other of the two horns of the now familiar dilemma: either thought is separate from the matter of experience, and then its validity is wholly its own private business; or else the objective results of thought are already in the antecedent material, and then thought is either unnecessary, or else has no way of checking its own performances.
1. Lotze assumes, as we have seen, a certain independent validity in each meaning or qualified content, taken in and of itself. "Blue" has a certain validity, or meaning, in and of itself; it is an object for consciousness as such. After the original sense-irritation through which it was mediated has entirely disappeared, it persists as a valid idea, as a meaning. Moreover, it is an object or content of thought for others as well. Thus it has a double mark of validity: in the comparison of one part of my own experience with another, and in the comparison of my experience as a whole with that of others. Here we have a sort of validity which does not raise at all the question of metaphysical reality (Vol. I, pp. 14, 15). Lotze thus seems to have escaped from the necessity of employing as check or test for the validity of ideas any reference to a real outside the sphere of thought itself. Such terms as "conjunction," "franchise," "constitution," "algebraic zero," etc., etc., claim to possess objective validity. Yet none of these professes to refer to a reality beyond thought. Generalizing this point of view, validity or objectivity of meaning means simply that which is "identical for all consciousness" (Vol. I, p. 3); "it is quite indifferent whether certain parts of the world of thought indicate something which has beside an independent reality outside of thinking minds, or whether all that it contains exists only in the thoughts of those who think it, but with equal validity for them all" (Vol. I, p. 16).
So far it seems clear sailing. Difficulties, however, show themselves, the moment we inquire what is meant by a self-identical content for all thought. Is this to be taken in a static or in a dynamic way? That is to say: Does it express the fact that a given content or meaning is de facto presented to the consciousness of all alike? Does this coequal presence guarantee an objectivity? Or does validity attach to a given meaning or content in so far as it directs and controls the further exercise of thinking, and thus the formation of further new contents of consciousness?
The former interpretation is alone consistent with Lotze's notion that the independent idea as such is invested with a certain validity or objectivity. It alone is consistent with his assertion that concepts precede judgments. It alone, that is to say, is consistent with the notion that reflective thinking has a sphere of ideas or meanings supplied to it at the outset. But it is impossible to entertain this belief. The stimulus which, according to Lotze, goads thought on from ideas or concepts to judgments and inferences, is in truth simply the lack of validity, of objectivity in its original independent meanings or contents. A meaning as independent is precisely that which is not invested with validity, but which is a mere idea, a "notion," a fancy, at best a surmise which may turn out to be valid (and of course this indicates possible reference); a standpoint to have its value determined by its further active use. "Blue" as a mere detached floating meaning, an idea at large, would not gain in validity simply by being entertained continuously in a given consciousness; or by being made at one and the same time the persistent object of attentive regard by all human consciousnesses. If this were all that were required, the chimera, the centaur, or any other subjective construction, could easily gain validity. "Christian Science" has made just this notion the basis of its philosophy.
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
