Secondly, it has been shown in recent times in psychoanalytic studies that symbols which were originally material pass over to functional use. If we thoroughly analyze for a sufficient time the dreams of a person we shall find that certain symbols which at first probably appeared only incidentally to signify some idea content, wish content, etc., return and become a persistent or typical form. And the more such a typical form is established and is impressed, the farther it is removed from its first ephemeral meaning, and the more it becomes a symbolic representative of a whole group of similar experiences, a spiritual capital, so to speak, till finally we can regard it simply as the representative of a spiritual current (love, hate, tendency to frivolity, to cruelty, to anxiety, etc.). What has been accomplished there is a transition from the material to the functional on the path of a determination inward or intro-determination (verinnerlichung) as I shall call it. Later I shall have more to say about intro-determination. For the present this may suffice for the understanding, that the material and the functional symbolism, in spite of their at first apparently fundamental difference, are essentially related in some way, which is illuminated by the process of intro-determination. The analogue of the problem of multiple interpretation unfolded in the preceding section is shown to be a question that can be easily answered. And we would bring our problem to a generally satisfactory position if we succeeded in showing that the anagogic interpretation, whose alignment with the psychoanalytic seemed so impracticable, is a form of functional interpretation, or at least related to it. In this case it would be at once comprehensible how a product of the imagination harmonizes with several expositions (problem of multiple interpretation); because this variety of sense had already operated in the selection of the symbol and indeed, in those cases as well where we did not at first sight suspect the coöperation of the anagogic thoughts; secondly, the anagogic and the psychoanalytic interpretations are somehow reconciled to each other, whereby possibly also the position of the natural science interpretation can be made somewhat clearer.
