The works which the Institute proposes to publish in this series derive from many different spheres of knowledge.
This is understandable since they are predominantly psychological in character.
Psychology, of its very nature, is the intermediary between the disciplines, for the psyche is the mother of all the sciences and arts.
Anyone who wishes to paint her portrait must mingle many colours on his palette.
In order to do justice to its subject, psychology has to rely on any number of auxiliary sciences, on whose findings its own growth and prosperity depend.
The psychologist gratefully acknowledges his borrowings from other sciences, though he has neither the intention nor the ambition to usurp their domains or to “know better.”
He has no wish to intrude into other fields but restricts himself to using their findings for his own purposes.
Thus, for example, he will not use historical material in order to write history but rather to demonstrate the nature of the psyche—-a concern which is foreign to the historian.
The forthcoming publications in this series will show the great diversity of psychological interests and needs.
Recent developments in psychological research, in particular the psychology of the collective unconscious, have confronted us with problems which require he collaboration of other sciences.
The facts and relationships unearthed by the analysis of the unconscious offer so many parallels to the phenomenology of myths, for example, that their psychological elucidation may also shed light on the mythological figures and their symbols.
At all events, we must gratefully acknowledge the invaluable support psychology has received from students of myths and fairy-tales, as well as from comparative religion, even if they on their part have not yet learnt how to make use of its insights.
The psychology of the unconscious is still a very young science which must first justify its existence before a critical public.
This is the end which the publications of the Institute are designed to serve. ~Carl Jung, CW 18, Pages 485-486
