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.
