The second definition of internal meaning is the one in which it is stated as the "partial expression," "embodiment," and "fulfilment" of a single conscious purpose, and in which subsequently and consequently the idea is identified with "any conscious act," for example, singing. The first part of the statement appears to say that the idea of a melody is in "partial fulfilment" of the idea regarded as the purpose to sing the melody. But, as the first statement of internal meaning implies, how can one have a purpose to sing the melody except in and through the idea? It is precisely the construction of an idea that transforms the vague "indefinite restlessness" and dissatisfaction into a purpose. The idea is the defining, the sharpening of the blind activity of mere sensation, mere want, into a plan of action. However, Mr. Royce meets this difficulty at once by the statement that the term "idea" here not only covers the activity involved in forming the idea, _e. g._, the idea of singing, but includes the action of singing, which fulfils this purpose. "In the same sense _any conscious act_ at the moment when you perform it not merely expresses, but is, in my present sense, an idea."[175] But this sort of an adjustment between the idea as the purpose and as the fulfilment of the purpose raises a new question. What here becomes of the distinction between immediate and mediating experience? Surely there is a pretty discernible difference between experience as a purposive idea and the experience which fulfils this purpose. To call them both "ideas" is at least confusing, and indeed it appears that it is just this confusion that obscures the fundamental difficulty in dealing, later on, with the problem of truth and error. To be sure, the very formation of the idea as the purpose, the "plan of action," is the beginning of the relief from the "indefinite restlessness." On the other hand, it defines and sharpens the dissatisfaction. When this vague unrest takes the form of a purpose to attain food or shelter, or to sing in tune, it is of course the first step toward solution. But this very definition of the dissatisfaction intensifies it. The idea as purpose, then, instead of being the fulfilment, appears to be the plan, the method of fulfilment. The fulfilling experience is the further experience to which the idea points and leads.
