The snake, about whose significance as a “negative phallus,” etc. [developed in detail by Jung], we shall have more to say, can also be regarded as a typical image. Bull, cow and other animal forms are in mythology as in dreams typical transmutations, with unlimited possibility of intro-determination. Dogs are often in dreams the representations of animal propensities. The beast is often “la bête humaine” in the dreamer’s own inner life. We have become acquainted with the terrible lions, the bears, etc., as father types; here we get a new perspective which makes clear the one-sidedness of our first conception. Since psychoanalysis has found acceptation, many of its followers believe they are able to solve, with their work of analysis alone, all the psychological, esthetic and mythological problems that come up. We understand only half of the psychic impulses, as indeed we do all spiritual development, if we look merely at the root. We have to regard not merely whence we come but also whither we go. Then only can the course of the psyche be comprehended, ontogenetically as well as phylogenetically, according to a dynamic scheme as it were. If we apply this fundamental principle to symbolism there develops therefrom the obligation to keep both visible poles in view, between which the advance of significance, the process of intro-determination is completed. (An externalization is also possible, yet the internalization or intro-determination must be regarded as the normal process.) [It corresponds namely to the process of education and progress of culture. This will soon be cleared up.] To the most general type belong then, without doubt, those symbols or frequently disguised images, concerning which we wondered before, that besides representing “titanic” tendencies, they are fitted to represent the anagogic. The solution of the riddle is found the instant we regard these images as types with a certain degree of intro-determination, as types for a few fundamental forces of the soul, with which we are all endowed, and whose typical symbols are for that reason of general applicability. [I will therefore call these types the human elementary types.] For example, if by psychoanalysis we deduce father and mother, etc., from some of the symbols appearing in dreams, we have in these representations of the psychic images, as the psychoanalyst calls them, in reality derived mere types whose meaning will change according to the ways of viewing them, somewhat as the color of many minerals changes according to the angle at which we hold them to the light. The actual father or mother, the experiences that surrounded them, were the material used in the formation of the types; they were external things even if important, while later the father, etc., emerging as symbol, may have significance as a type of the spiritual power of the very person in question; a spiritual power to be sure, which the person in
