Essays in Experimental Logic

by John Dewey

Lotze is explicit upon the point that only the thought-content in which the process of thinking issues 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" (II, 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 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. The question is 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 the phase of the transformation which the course of experience (whether practical, or artistic, or socially affectional or whatever) undergoes for the sake of its deliberate control. 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 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 thoroughly self-contradictory. 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 which is 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 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 building is not set over against the completed building as mere means to an end; it is the end taken in process or historically, longitudinally, temporally 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 accidentally 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 matters or meanings, not of ideas as existences or events; and that the type of association we call thinking differs from casual fancy and revery by control in reference to an end, to apprehend how completely thinking is a reconstructive movement of actual contents of experience in relation to each other.

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.

This is not a formal question, but one of the place and relations of the matters actually entering into experience. And they in turn determine 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 the practice of knowing when it sticks close by and observes the directions and checks inherent in each successive phase of the evolution of the cycle of experience. 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 (see ante, p. 95).

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 arises and will not down. We may reconstruct the 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 subject-matter of a hallucination does not gain validity in proportion to its social contagiousness.

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 (II, 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" (II, 185). "It is then this varied world of ideas within us which forms the sole material directly given to us" (II, 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 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 although unknowable is yet taken as the ultimate test of the value of our ideas. 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.
