The problem of thought as activity, as distinct from thought as content, opens up altogether too large a question to receive complete consideration at this point. Fortunately, however, the previous discussion enables us to narrow the point which is in issue just here. The question is whether the activity of thought is to be regarded as an independent function supervening entirely from without upon antecedents, and directed from without upon data, or whether it marks the phase of the transformation which the course of experience (whether practical, or artistic, or socially affectional or whatever) undergoes for the sake of its deliberate control. If it be the latter, a thoroughly intelligent sense can be given to the proposition that the activity of thinking is instrumental, and that its worth is found, not in its own successive states as such, but in the result in which it comes to conclusion. But the conception of thinking as an independent activity somehow occurring after an independent antecedent, playing upon an independent subject-matter, and finally effecting an independent result, presents us with just one miracle the more. I do not question the strictly instrumental character of thinking. The problem lies not here, but in the interpretation of the nature of the instrument. The difficulty with Lotze's position is that it forces us into the assumption of a means and an end which are simply and only external to each other, and yet necessarily dependent upon each other--a position which, whenever found, is thoroughly self-contradictory. Lotze vibrates between the notion of thought as a tool in the external sense, a mere scaffolding to a finished building in which it has no part nor lot, and the notion of thought as an immanent tool, as a scaffolding which is an integral part of the very operation of building, and which is set up for the sake of the building-activity which is carried on effectively only with and through a scaffolding. Only in the former case can the scaffolding be considered as a _mere_ tool. In the latter case the external scaffolding is _not_ the instrumentality; the actual tool is the _action_ of erecting the building, and this action involves the scaffolding as a constituent part of itself. The work of building is not set over against the completed building as mere means to an end; it _is_ the end taken in process or historically, longitudinally, temporally viewed. The scaffolding, moreover, is not an external means to the process of erecting, but an organic member of it. It is no mere accident of language that "building" has a double sense--meaning at once the process and the finished product. The outcome of thought is the thinking activity carried on to its own completion; the activity, on the other hand, _is_ the outcome taken anywhere short of its own realization, and thereby still going on.
