These are distinctions which arise only when the instrument of action has been questioned and the mind turns back upon the meaning which it has unhesitatingly used, analyzing, investigating, constructing, laying bare the method and function of its tools. Thus arises a new and distinctive type of judgment, viz., the reflective.
2. The reflective judgment.—By the reflective judgment is to be understood that form of meaning whose structure and function have become a problem to itself. The days of naïve trust and spontaneous action have gone by. Inquiry, criticism, aloofness, stay the tendency to immediate action. Meaning has grown worldly wise and demands that each situation shall explain itself and that the general principles and concrete applications of its own instruments shall be made manifest. Hence in the various forms of reflective thought we find the progressive steps in which meaning comes to full consciousness of its function in experience.
The demonstrative judgment (the simplest of the reflective type) carries doubt, criticism, construction, and assertion written on the face of it. For example, in the expression, "That is hot," we do not find the directness and immediacy of response characteristic of the simpler impersonal "hot." Instead, we note a clash of tendencies, a suspension of the proposed action, a demand for and a carrying out of a reconsideration of the course of action, the emergence of a new meaning, and the consequent redirection of activities. An iron lies upon the hearth; I stretch out my hand to return it to its place; I stop suddenly, having become conscious of signs of warmth; the thought arises in my mind, "That is hot;" I experiment and find my judgment correct; I search for a cloth, and thus protected carry out my first intention. Again, a hunter notes a movement in the thicket, quickly raises his gun, and is about to fire. Something in the movement of the object arrests him. He stops, thinking, "That is a man, perhaps." What has caught the eye has arrested his action, has become a demand, and not until the situation has become clear can the hunter determine what to do. In other words, he must reflectively assure himself what the object is before he can satisfy himself as to how he should act. Subject and predicate have arisen and have consciously played their parts in the passage from doubt to decision.
Under the heading "individual judgments" are classed such expressions as, "That ship is a man-o'-war," "Russia opposes the policy of the open door in China." In both these cases it is evident that an advance in definiteness of conception and of complexity of meaning has been made, while at the same time we recognize that the instrumental characteristics of the thought-movement remain the same. In considering the subject of the judgment we note that the stimulus presents itself partly as a determinate factor and partly as a problem—an insistent demand. The expression, "That ship is a man-o'-war," might be written, "That is a ship and of the kind man-o'-war," and it thus constitutes what Sigwart calls a "double synthesis." As used in actual judgment, however, the two are held together and constitute the statement of a single stimulus of which a certain portion is evident and a certain portion is in doubt. The working out of the difficulty is given in the predicate "is a man-o'-war," in which we at once detect the instrumental characteristics fundamental to all judgment. To illustrate: At the close of the battle of Santiago, in the Spanish-American war, smoke appeared upon the horizon revealing the presence of a strange ship. Instantly attention was directed to it, and it became a problem for action—a demand for instrumental information. Soon it was identified as a man-o'-war, and the American ships were cleared for action. Closer approach raised a further question with reference to its nationality. After some debate this also was resolved, and hostile demonstrations were abandoned.
The universal judgment is sometimes said to exhibit two distinct forms. Investigation, however, has proved this statement to be incorrect. Instances taken in themselves and apart from their character are of no logical significance. Advance is made by weighing instances and not by counting them. In short, the true universal is the hypothetical judgment, and the reason for this may be readily shown. The hypothetical judgment is essentially double-ended. On the one hand, it is a statement of the problem of action in terms of the conditions which will turn the problem into a solution. On the other hand, it is an assertion that once the conditions of action have been determined the result desired may be attained. Here we note that the judgment has come to clear consciousness of itself and of the part which it plays in experience. It has now obtained an insight into the criterion of its legitimate employment, i. e., of its truth and falsity. And this insight makes the justification of its claim almost self-evident. For, inasmuch as the hypothetical judgment says, "If such and such conditions be realized, such and such a result will be obtained," the test of the claim is made by putting the conditions into effect and watching whether the promised experience is given. And further, since it has been found that the judgment formulated as a hypothesis actually accomplishes what it promises, we must admit that the hypothetical judgment is also categorical. These two factors cannot be separated from each other. It is true that the hypothetical judgment reduces every valid meaning to the form, "If certain conditions be realized," but it as plainly and positively asserts, "such and such results will be obtained." When we grasp the absolute correlativity of the hypothetical and categorical aspects of judgment, we realize at once the essentially instrumental character of judgment, when it comes to consciousness of its structure and function. It arises in the self-conscious realization of a problem. This it reflects upon and sizes up. When the difficulty has been apprehended, the judgment emerges as the consciousness of the conditions which will attain the desired end of action freed and unimpeded. This may be illustrated by reference to the work of Pasteur cited above. His investigations began in a problem set for him by agricultural conditions in France. A certain disease had made the profitable rearing of sheep and cattle almost an impossibility. After long and careful examination he discovered the beneficial effects of vaccination. To him the conditions which governed the presence of the disease became apparent, and this knowledge furnished him with an instrument by means of which one difficulty was removed from the path of the stock-raiser. In this illustration we have an epitome of the work accomplished everywhere by the scientist. It is his task to develop and to reduce to exact terms instruments of control for the varied activities of life. In its parts and as a whole each instrument is intelligently constructed and tested so that its make-up and function are exactly known. Because of this, reasoned belief now takes the place of unreflective trust as that was experienced in the impersonal stage of judgment. What at first hand might appear to be a loss was in reality a gain; the breakdown of the impersonal was the first step in the development of an instrument of action conscious of its reason for being, its methods and conditions of action. These latter constitute the distinctive subject and predicate of the reflective judgment.
This brings us to the connection between the hypothetical character of this form of judgment and its universality. And this perhaps will now be quite apparent. The reflective judgment lays bare an objective connection between the conditions and outcomes of actions. It proves its point by actually constructing the event. Such being the case, universality is no more than a statement of identical results being predictable wherever like conditions are realized. If it be true that "man is mortal," then it is an identical statement to insist that, "Wherever we find men there we shall also find mortality."
And this point brings us naturally to the treatment of the disjunctive judgment: "A is either B or C or D." In the disjunctive judgment the demand is not for the construction of a reliable instrument of action, but for the resolution of a doubt as to which instrument is precisely fitted to the circumstances. In fact, the disjunctive judgment involves the identification of the practical problem. When we say of a man, "He is either very simple or very deep," we have no doubt as to our proper course of action in either case. If he is simple, then we shall do so and so; if he is deep, then another course of action follows. We can lay out alternative courses beforehand, but the point of difficulty lies here: "But just which is he?" In short, the disjunctive judgment is the demand for and the attempt at a precise diagnosis of a concrete problem. To illustrate: A patient afflicted with aphasia is brought to a physician. The fact that the trouble is aphasia may be quite evident. But what precisely is the form and seat of the aphasia? To the mind of the educated physician the problem will take on the disjunctive form: "This is either subcortical or cortical aphasia. If subcortical, intelligence will not be impaired; if cortical, the sensor and motor tracts will be in good condition." Appropriate tests are made and the subcortical
