As I am not making a metaphysical judgment, I cannot help remarking that at least in our empirical world the opposites are inexorably at work and that, without them, this world would not exist. ~Carl Jung, CW 18, Para 1640
I merely hold that metaphysics cannot be an object of science, which does not mean that numinous experiences do not happen frequently, particularly in the course of an analysis or in the life of a truly religious individual. ~Carl Jung, CW 18, Para 1591
Psychological truths are not metaphysical insights; they are habitual modes of thinking, feeling, and behaving that experience has proved appropriate and useful. ~Carl Jung, CW 9ii, para 50.
Psychology cannot establish any metaphysical “truths,” nor does it try to. ~Carl Jung, CW 18, Para 742
They [Symbols] are just no Gnosis, no metaphysical assertions. They are partly even futile or dubious attempts at pronouncing the ineffable. ~Carl Jung, Letters Vol. II, Page 291.
As one habitually identifies the “psyche” with what one knows of it, it is assumed that one can call certain (supposed or believed) metaphysical entities non-psychic. ~Carl Jung, CW 18, Para 1649
As I see it, the psyche is a world in which the ego is contained. Maybe there are fishes who believe that they contain the sea. We must rid ourselves of this habitual illusion of ours if we wish to consider metaphysical assertions from the standpoint of psychology. ~Carl Jung, CW 13 Para 51.
About God himself I have asserted nothing, because according to my premise nothing whatever can be asserted about God himself. All such assertions refer to the psychology of the God-image. Their validity is therefore never metaphysical but only psychological. ~Carl Jung, Letters Vol. 1, Page 294.
