itself as a moment or phase in the total psychosis. Value is not to be understood apart from what Urban calls its "presuppositions."[131] Every value presupposes a going on of activity, and is intimately linked with the total psychosis,--a moving focal point of clear consciousness, with a surrounding area of vaguer processes, gradually shading off into the subconscious and unconscious at the borders. Every value is linked with the whole body of ideas, emotions, habits, instincts, impulses, which, in their organic totality, we call the personality. Back of the value stands a long history, which persists into the present in the form of dispositions and activities, of which we are unconscious so long as they are unimpeded, but which spring into consciousness at once if arrested. If the object be one that appeals to simple biological impulses, we may, as a rule, safely abstract from most of these "presuppositions," and centre attention upon the biological impulse and its accompanying feelings and ideas. But as we rise to objects that appeal to wider and higher interests, the essential presuppositions include more and more till, in vital ethical values, virtually the whole personality is essentially involved. Of these presuppositions, or "funded meaning," we need not be conscious in any detail. The value, which is the emotional-volitional aspect of this funded meaning, is, of course, sufficient, so long as it is unchallenged by an opposing value, for the motivation of our activity--which is the essential function of values. The presuppositions tend to become explicit when the value is challenged by another value, though they never come entirely into light, in the case of the higher values, and to make them even approximately clear is the work of long conflict in an introspective mind. A frequent result of conflicts among values is a sort of mechanical "haul and strain," producing "more heat than light." The question of the relations among values is a separate topic, which will be discussed for its own sake later. We are here interested in it as making clearer the nature of the "presuppositions" of value.
