are made and the subcortical possibilities are shut out. The disjunction disappears and the judgment emerges: "This is a case of cortical aphasia." But now a new disjunction arises. It is either the sensory or motor form of cortical aphasia, and, whichever one of these, it is again one of several possibilities. As the alternatives arise, the means for discriminating them arise also; determinate symptoms are observed, and in due time the physician arrives at the final conclusion: "This is sensory cortical aphasia of the visual type." Having determined this, his method of action is assured, and he proceeds to the appropriate operation. Thus, finally, we are brought to a form of judgment aware not only of its motive, method, and justification, but also to one aware of its specific application to individual cases. Thus it would seem as though judgment had returned upon itself and had completed the determination of its sphere of action. And in one sense this is true. In the disjunctive judgment, as inclusive of the motives of the hypothetical and categorical forms, the reflective judgment would appear to have come to its limit of development. One thing, however, remains to be considered, viz., the development from crude to expert uses of intellectual instruments.

      3. The intuitive judgment.—As stated above, the intuitive type of judgment depends upon efficiency in the use of judgment. In this regard there is a great similarity between the impersonal and the intuitive judgments. Both are immediate and precise. But there is a radical and essential difference. The impersonal judgment knows nothing of the strict analysis, insight, and constructive power of the reflective judgment. The intuitive judgment, on the other hand, includes the results of reflection and brings them to their highest power. Paradoxically put, in the intuitive judgment there is so much reflection that there is no need for it at all. To the intuitive judgment there is no hesitation, no aloofness. Action is direct, but entirely self-conscious. That such a type of judgment as the intuitive exists there can be no doubt. There is all the difference in the world between the quality of consciousness of a mere layman and that of an expert, no matter what the line. The layman must size up a situation. It is a process whose parts are successive, whether much or little difficulty be experienced. For the expert situations are taken in at a glance, parts and whole are simultaneous and immediate. Yet the meaning is entirely exact. The expert judgment is self-conscious to the last degree. While other individuals are thinking out what to do, the expert has it, sees the advantage, adjusts, and moves. Demand and solution jump together. How otherwise can we explain, for example, the action of an expert ball-player? Witness his rapid reactions, his instantaneous adjustments. Mistakes of opponents which would never be noticed by the average player are recognized and seized upon. On the instant the new opening is seen, the adjustment is evident, the movement made. Illustrations to the same effect could be drawn from other modes of life, e. g., music, the military life, etc. That intuitive judgments are not more common is a proof in itself of their distinctive character and value. Only in so far as we become experts in our special fields of experience and have reduced our instruments of action to precise control, can we expect the presence of intuitive judgments. They remain, therefore, as the final outcome of the judgment-function made perfect in its technique and use.

      In conclusion we shall make a brief summary of our investigation and a criticism of certain current theories of judgment.

      Judgment is essentially instrumental. Its function is to construct, justify, and refine experience into exact instruments for the direction and control of future experience through action. It exhibits itself first in the form of instruments developed unsystematically in response to the hard necessities of life. In a higher stage of development the instrumental process itself is taken into account, and systematically developed until in the methodical procedure of science the general principles of knowledge are laid bare and efficient instruments of action constructed. Finally, constant, intelligent use results in complete control, so that within certain spheres doubt and hesitancy would seem to disappear as to the character of the tools used, and remain only as a moment in determining their wisest or most appropriate employ.

      The criticism indicated is based upon the instrumental character of judgment and is directed against all theories which contend that knowledge is a "copying" or "reproducing" of reality. In whatever form this "copy" theory be stated, the question inevitably arises how we can compare our ideas with reality and thus know their truth. On this theory, what we possess is ever the copy; the reality is beyond. In other words, such a theory logically carried out leads to the breakdown of knowledge. Only a theory which contains and constructs its criterion within its own specific movement can verify its constructions. Such a theory is the instrumental. Judgment constructs a situation in consciousness. The values assigned in this situation have a determining influence upon values further appreciated. The construction arrived at concerns future weal and woe. Thus gradually a sense of truth and falsity attaches to the construing of situations. One sees that he must look beyond this situation, because the way he estimates this situation is fraught with meaning beyond itself. Hence the critically reflective judgment in which hesitancy and doubt direct themselves at the attitude, elements, and tools involved in defining and identifying the situation, instead of at the situation itself in toto. Instead of developing a complex of experience through assigning qualities and meanings to the situation as such, some one of the quales is selected, to have its significance determined. It becomes, pro tempore, the situation judged. Or the same thing takes place as regards some "idea" or value hitherto immediately fastened upon and employed. In either case we get the reflective judgment, the judgment of pure relationship as distinct from the constructive judgment. But the judgment of relation, employing the copula to refer a specified predicate to a specified object, is after all only for the sake of controlling some immediate judgment of constructive experience. It realizes itself in forming the confident habit of prompt and precise mental adjustment to individualized situations.

       The Nature of Hypothesis

       Table of Contents

      In the various discussions of the hypothesis which have appeared in works on inductive logic and in writings on scientific method, its structure and function have received considerable attention, while its origin has been comparatively neglected. The hypothesis has generally been treated as that part of scientific procedure which marks the stage where a definite plan or method is proposed for dealing with new or unexplained facts. It is regarded as an invention for the purpose of explaining the given, as a definite conjecture which is to be tested by an appeal to experience to see whether deductions made in accordance with it will be found true in fact. The function of the hypothesis is to unify, to furnish a method of dealing with things, and its structure must be suitable to this end. It must be so formed that it will be likely to prove valid, and writers have formulated various rules to be followed in the formation of hypotheses. These rules state the main requirements of a good hypothesis, and are intended to aid in a general way by pointing out certain limits within which it must fall.

      In respect to the origin of the hypothesis, writers have usually contented themselves with pointing out the kind of situations in which hypotheses are likely to appear. But after this has been done, after favorable external conditions have been given, the rest must be left to "genius," for hypotheses arise as "happy guesses," for which no rule or law can be given. In fact, the genius differs from the ordinary plodding mortal in just this ability to form fruitful hypotheses in the midst of the same facts which to other less gifted individuals remain only so many disconnected experiences.

      This unequal stress which has been laid on the structure and function of the hypothesis in comparison with its origin may be attributed to three reasons: (1) The facts, or data, which constitute the working material of hypotheses are regarded as given to all alike, and all alike are more or less interested in systematizing and unifying experience. The purpose of the hypothesis and the opportunity for forming it are thus practically the same for all, and hence certain definite rules can be laid down which will apply to all cases where hypotheses are to be employed. (2) But beyond this there seems to be no clue that can be formulated. There is apparently a more or less open acceptance of the final answer of the boy Zerah Colburn, who, when pressed to give an explanation of his method of instantaneous calculation, exclaimed in despair: "God put
