Essays in Experimental Logic

by John Dewey

The logic of subsumption in the physical sciences meant that a given state of things could be compared with a ready-made concept as a model—the phenomena of the heavens with the implications of, say, the circle. The methods of experimental science broke down this motion; they substituted for an alleged regulative model a formula which was the integrated function of the particular phenomena themselves, a formula to be used as a method of further observations and experiments and thereby tested and developed. The unwillingness to believe that, in a similar fashion, moral standards or models can be trusted to develop out of the specific situations of action shows how little the general logical force of the method of science has been grasped. Physical knowledge did not as matter of fact advance till the dogma of models or forms as standards of knowledge had been ousted. Yet we hang tenaciously to a like doctrine in morals for fear of moral chaos. It once seemed to be impossible that the disordered phenomena of perception could generate a knowledge of law and order; it was supposed that independent principles of order must be supplied and the phenomena measured by approach to or deviation from the fixed models. The ordinary conception of a standard in practical affairs is a precise analogue. Physical knowledge started on a secure career when men had courage to start from the irregular scene and to treat the suggestions to which it gave rise as methods for instituting new observations and experiences. Acting upon the suggested conceptions analyzed, extended, and ordered phenomena and thus made improved conceptions—methods of inquiry—possible. It is reasonable to believe that what holds moral knowledge back is above all the conception that there are standards of good given to knowledge apart from the work of reflection in constructing methods of action. As the bringer of bad news gets a bad name, being made to share in the production of the evil which he reports, so honest acknowledgment of the uncertainty of the moral situation and of the hypothetical character of all rules of moral mensuration prior to acting upon them, is treated as if it originated the uncertainty and created the skepticism.

It may be contended, however, that all this does not justify the earlier statement that the limiting situation which occasions and cuts off judgment is not itself a value. Why, it will be asked, does a man buy a suit of clothes unless that is a value, or at least a proximate means to a further value? The answer is short and simple: Because he has to; because the situation in which he lives demands it. The answer probably seems too summary. But it may suggest that while a man lives, he never is called upon to judge whether he shall act, but simply how he shall act. A decision not to act is a decision to act in a certain way; it is never a judgment not to act, unqualifiedly. It is a judgment to do something else—to wait, for example. A judgment that the best thing to do is to retire from active life, to become a Simon Stylites, is a judgment to act in a certain way, conditioned upon the necessity that, irrespective of judging, a man will have to act somehow anyway. A decision to commit suicide is not a decision to be dead; it is a decision to perform a certain act. The act may depend upon reaching the conclusion that life is not worth living. But as a judgment, this is a conclusion to act in a way to terminate the possibility of further situations requiring judgment and action. And it does not imply that a judgment about life as a supreme value and standard underlies all judgments as to how to live. More specifically, it is not a judgment upon the value of life per se, but a judgment that one does not find at hand the specific means of making life worth while. As an act to be done, it falls within and assumes life. As a judgment upon the value of life, by definition it evades the issue. No one ever influenced a person considering committing suicide by arguments concerning the value of life, but only by suggesting or supplying conditions and means which make life worth living; in other words, by furnishing direct stimuli to living.

However, I fear that all this argument may only obscure a point obvious without argument, namely, that all deliberation upon what to do is concerned with the completion and determination of a situation in some respect incomplete and so indeterminate. Every such situation is specific; it is not merely incomplete; the incompleteness is of a specific situation. Hence the situation sets limits to the reflective process; what is judged has reference to it and that which limits never is judged in the particular situation in which it is limiting. Now we have in ordinary speech a word which expresses the nature of the conditions which limit the judgments of value. It is the word "invaluable." The word does not mean something of supreme value as compared with other things any more than it means something of zero value. It means something out of the scope of valuation—something out of the range of judgment; whatever in the situation at hand is not and cannot be any part of the subject-matter of judgment and which yet instigates and cuts short the judgment. It means, in short, that judgment at some point runs against the brute act of holding something dear as its limit.

V

The statement that values are determined in the process of judgment of what to do (that is, in situations where preference depends upon reflection upon the conditions and possibilities of a situation requiring action) will be met by the objection that our practical deliberations usually assume precedent specific values and also a certain order or grade among them. There is a sense in which I am not concerned to deny this. Our deliberate choices go on in situations more or less like those in which we have previously chosen. When deliberation has reached a valuation, and action has confirmed or verified the conclusion, the result remains. Situations overlap. The m which is judged better than n in one situation is found worse than l in another, and so on; thus a certain order of precedence is established. And we have to broaden the field to cover the habitual order of reflective preferences in the community to which we belong. The valu-eds or valuables thus constituted present themselves as facts in subsequent situations. Moreover, by the same kind of operation, the dominating objects of past valuations present themselves as standardized values.

But we have to note that such value-standards are only presumptive. Their status depends, on one hand, upon the extent in which the present situation is like the past. In a progressive or rapidly altering social life, the presumption of identical present value is weakened. And while it would be foolish not to avail one's self of the assistance in present valuations of the valuables established in other situations, we have to remember that habit operates to make us overlook differences and presume identity where it does not exist—to the misleading of judgment. On the other hand, the contributory worth of past determinations of value is dependent upon the extent in which they were critically made; especially upon the extent in which the consequences brought about through acting upon them have been carefully noted. In other words, the presumptive force of a past value in present judgment depends upon the pains taken with its verification.

In any case, so far as judgment takes place (instead of the reminiscence of a prior good operating as a direct stimulus to present action) all valuation is in some degree a revaluation. Nietzsche would probably not have made so much of a sensation, but he would have been within the limits of wisdom, if he had confined himself to the assertion that all judgment, in the degree in which it is critically intelligent, is a transvaluation of prior values. I cannot escape recognition that any allusion to modification or transformation of an object through judgment arouses partisan suspicion and hostility. To many it appears to be a survival of an idealistic epistemology. But I see only three alternatives. Either there are no practical judgments—as judgments they are wholly illusory; or the future is bound to be but a repetition of the past or a reproduction of something eternally existent in some transcendent realm (which is the same thing logically),[89] or the object of a practical judgment is some change, some alteration, to be brought about in the given, the nature of the change depending upon the judgment and yet constituting its subject-matter. Unless the epistemological realist accepts one of the two first alternatives, he seems bound, in accepting the third, to admit not merely that practical judgments make a difference in things as an after-effect (this he seems ready enough to admit), but that the import and validity of judgments is a matter of the difference thus made. One may, of course, hold that this is just what marks the distinction of the practical judgment from the scientific judgment. But one who admits this fact as respects a practical judgment can no longer claim that it is fatal to the very idea of judgment to suppose that its proper object is some difference to be brought about in things, and that the truth of the judgment is constituted by the differences in consequences actually made. And a logical realist who takes seriously the notion that moral good is a fulfilment of an organization or integration must admit that any proposition about such an object is prospective (for it is something to be attained through action), and that the proposition is made for the sake of furthering the fulfilment. Let one start at this point and carry back the conception into a consideration of other kinds of propositions, and one will have, I think, the readiest means of apprehending the intent of the theory that all propositions are but the propoundings of possible knowledge, not knowledge itself. For unless one marks off the judgment of good from other judgment by means of an arbitrary division of the organism from the environment, or of the subjective from the objective, no ground for any sharp line of division in the propositional-continuum will appear.

But (to obviate misunderstanding) this does not mean that some psychic state or act makes the difference in things. In the first place, the subject-matter of the judgment is a change to be brought about; and, in the second place, this subject-matter does not become an object until the judgment has issued in act. It is the act which makes the difference, but nevertheless the act is but the complete object of judgment and the judgment is complete as a judgment only in the act. The anti-pragmatists have been asked (notably by Professor A. W. Moore) how they sharply distinguish between judgment—or knowledge—and act and yet freely admit and insist that knowledge makes a difference in action and hence in existence. This is the crux of the whole matter. And it is a logical question. It is not a query (as it seems to have been considered) as to how the mental can influence a physical thing like action—a variant of the old question of how the mind affects the body. On the contrary, the implication is that the relation of knowledge to action becomes a problem of the action of a mental (or logical) entity upon a physical one only when the logical import of judgment has been misconceived. The positive contention is that the realm of logical propositions presents in a realm of possibility the specific rearrangement of things which overt action presents in actuality. Hence the passage of a proposition into action is not a miracle, but the realization of its own character—its own meaning as logical. I do not profess, of course, to have shown that such is the case for all propositions; that is a matter which I have not discussed. But in showing the tenability of the hypothesis that practical judgments are of that nature, I have at least ruled out any purely dialectic proof that the nature of knowledge as such forbids entertaining the hypothesis that the import—indirect if not direct—of all logical propositions is some difference to be brought about. The road is at least cleared for a more unprejudiced consideration of this hypothesis on its own merits.

SENSE PERCEPTION AS KNOWLEDGE

I mentioned incidentally in the first section that it is conceivable that failure to give adequate consideration to practical judgments may have a compromising effect upon the consideration of other types. I now intend to develop this remark with regard to sense perception as a form of knowledge. The topic is so bound up with a multitude of perplexing psychological and epistemological traditions that I have first to make it reasonably clear what it is and what it is not which I propose to discuss. I endeavored in an earlier series of papers[90] to point out that the question of the material of sense perception is not, as such, a problem of the theory of knowledge at all, but simply a problem of the occurrence of a certain material—a problem of causal conditions and consequences. That is to say, the problem presented by an image[91] of a bent stick, or by a dream, or by "secondary" sensory qualities is properly a problem of physics—of conditions of occurrence, and not of logic, of truth or falsity, fact or fiction. That the existence of a red quale is dependent upon disturbances of a certain velocity of a medium in connection with certain changes of the organism is not to be confused with the notion that red is a way of knowing, in some more or less adequate fashion, some more "real" object or else of knowing itself. The fact of causation—or functional dependence—no more makes the quale an "appearance" to the mind of something more real than itself or of itself than it makes bubbles on the water a real fish transferred by some cognitive distortion into a region of appearance. With a little stretching we may use the term appearance in either case, but the term only means that the red quale or the water-bubble is an obvious or conspicuous thing from which we infer something else not so obvious.
