The predicate of the judgment is that part of the total experience which is taken as doubtful, or tentative. As we have seen, every act of adaptation involves a definite situation to be reacted to (subject) and an indefinite or tentative material with which to react (predicate). We have pointed out that a situation which demands a judgment never appears in consciousness as mere questioned or questionable situation.[52] There is always present, as soon as the doubt arises, some sort of tentative solution. This is the predicate or idea. Just as the fact, or real in the narrower sense, is that which is taken as given in the situation, so the ideal is that which is taken as tentative. Its ideality does not consist in its reference to another order of existence, the objective world of meanings, but in its function within the judgment, the estimate of the whole situation as leading up to the adequate act. Just as we no longer have any need for the mediation of the _real world as known to me_ between subject and reality, so we no longer need _the objective world of meanings_ to bridge the chasm between the predicate and reality. The difficulty of understanding how ideas can be used to build up facts disappears when we regard fact and idea, not as different orders of existence, but as contents marking different phases of a total function. Ideas, as Bosanquet represented them, proved to be extremely unsatisfactory tools to use in building up a knowledge of reality. In the first place, their value as instruments of thought depends upon their universality. We have already reviewed Bosanquet's difficulties in attempting to explain the universality of ideas. The universality of an idea cannot reside in its mere existence as image. Its existence is purely particular. Its universality must reside in its reference to something outside of itself. But no explanation of how the particular existence--image--could refer to another and fuller content of a different order of existence could be discovered. The fact of reference remained an ultimate mystery. From the new point of view the image gains its universality through its organizing function. It represents an organized habit which may be brought to bear upon the present situation, and which serves, by directing action, to organize and unify experience as a whole. It is only as function that the concept of reference can be made intelligible.
