The aim of the predicate is not to bunch all possible meaning and refer it in one final act indiscriminately to all existence, but to state the standpoint and method through which the difficulty of the particular situation may most effectively be dealt with. The selection of what is relevant to the characterization of the problem and the projection of the method of dealing with it are theoretic, hypothetic, intellectual:--that is, they are tentative ways of viewing the matter for the sake of guiding, economizing, and freeing the activities through which it may _really_ be dealt with. 3. The criterion of the worth of the idea is thus the capacity of the idea (as a definition of the end or outcome in terms of what is likely to be serviceable as a method) to operate in fulfilling the object for the sake of which it was projected. Capacity of operation in this fashion is the test, measure, or criterion of truth. Hence the criterion is practical in the most overt sense of that term. We may, if we choose, regard the object in which the idea terminates through its use in guiding action, as the criterion; but if we so choose, it is at our peril that we forget that this object serves as criterion in its capacity of fulfilment and not as sheer objective existence. 4. Difficulties overlap; problems recur which resemble each other in the kind of treatment they demand for solution. Various modes of activity with their respective ends, going on at some time more or less independently, get organized into single comprehensive systems of behavior. The solution of one problem is found to create difficulties elsewhere; or the truth that is made in the solution of one problem is found to afford an effective method of dealing with questions arising apparently from unallied sources. Thus certain tested ideas in performing a constant or recurrent function secure a certain permanent status. The prospective use of such truths, the satisfaction that we anticipate in their employ, the assurance of control that we feel in their possession, becomes relatively much more important than the circumstances under which they were first made true. In becoming permanent resources, such tested ideas get a generalized energy of position. They are truths in general, truths “in themselves” or in the abstract, truths to which positive value is assigned on their own account. Such truths are the “eternal truths” of current discussion. They naturally and properly add to their intellectual and to their practical worth a certain esthetic quality. They are interesting to contemplate, and their contemplation arouses emotions of admiration and reverence. To make these emotions the basis of assigning peculiar inherent sanctity to them apart from their warrant in use, is simply to give way to that mood which in primitive man is the cause of attributing magical efficacy to physical things. Esthetically such truths are more than instrumentalities. But to ignore both the
