Carl Jung wrote much of his work in German.
Difficulties for translation arise because the German word Seele means both psyche and soul. Jung was careful to define what he meant by psyche and by soul.
I have been compelled, in my investigations into the structure of the unconscious, to make a conceptual distinction between soul and psyche.
By psyche, I understand the totality of all psychic processes, conscious as well as unconscious.
By soul, on the other hand, I understand a clearly demarcated functional complex that can best be described as a “personality”. (Jung, 1971: Def. 48 par. 797)
[The translation of the German word Seele presents almost insuperable difficulties on account of the lack of a single English equivalent and because it combines the two words “psyche” and “soul” in a way not altogether familiar to the English reader.
For this reason some comment by the Editors will not be out of place.]
[In previous translations, and in this one as well, psyche– for which Jung in the German original uses either Psyche or Seele– has been used with reference to the totality of all psychic processes (cf. Jung, Psychological Types, Def. 48); i.e., it is a comprehensive term. Soul, on the other hand, as used in the technical terminology of analytical psychology, is more restricted in meaning and refers to a “function complex” or partial personality and never to the whole psyche.
It is often applied specifically to “anima” and “animus”; e.g., in this connection it is used in the composite word “soul-image” (Seelenbild). This conception of the soul is more primitive than the Christian one with which the reader is likely to be more familiar.
In its Christian context it refers to “the transcendental energy in man” and “the spiritual part of man considered in its moral aspect or in relation to God.” . . . –Editors.] (Jung, 1968: note 2 par. 9)
