“Some split between the inner world and outer world is common to all behaviour, and the need to bridge the gap is the source of creative behaviour.”

Draft for a Statement of Human Obligation (1943)
Context: There is a reality outside the world, that is to say, outside space and time, outside man's mental universe, outside any sphere whatsoever that is accessible to human faculties.
Corresponding to this reality, at the centre of the human heart, is the longing for an absolute good, a longing which is always there and is never appeased by any object in this world.
Another terrestrial manifestation of this reality lies in the absurd and insoluble contradictions which are always the terminus of human thought when it moves exclusively in this world.
Just as the reality of this world is the sole foundation of facts, so that other reality is the sole foundation of good.
That reality is the unique source of all the good that can exist in this world: that is to say, all beauty, all truth, all justice, all legitimacy, all order, and all human behaviour that is mindful of obligations.
Those minds whose attention and love are turned towards that reality are the sole intermediary through which good can descend from there and come among men.
Although it is beyond the reach of any human faculties, man has the power of turning his attention and love towards it.
Nothing can ever justify the assumption that any man, whoever he may be, has been deprived of this power.
It is a power which is only real in this world in so far as it is exercised. The sole condition for exercising it is consent.
This act of consent may be expressed, or it may not be, even tacitly; it may not be clearly conscious, although it has really taken place in the soul. Very often it is verbally expressed although it has not in fact taken place. But whether expressed or not, the one condition suffices: that it shall in fact have taken place.
To anyone who does actually consent to directing his attention and love beyond the world, towards the reality that exists outside the reach of all human faculties, it is given to succeed in doing so. In that case, sooner or later, there descends upon him a part of the good, which shines through him upon all that surrounds him.

Letter to Markus Fierz (1948)
Context: What now is the answer to the question as to the bridge between the perception of the senses and the concepts, which is now reduced to the question as to the bridge between the outer perceptions and those inner image-like representations. It seems to me one has to postulate a cosmic order of nature — outside of our arbitrariness— to which the outer material objects are subjected as are the inner images... The organizing and regulating has to be posited beyond the differentiation of physical and psychical... I am all for it to call this "organizing and regulating" "archetypes." It would then be inadmissible to define these as psychic contents. Rather, the above-mentioned inner pictures (dominants of the collective unconscious, see Jung) are the psychic manifestations of the archetypes, but which would have to produce and condition all nature laws belonging to the world of matter. The nature laws of matter would then be the physical manifestation of the archetypes.

Context: The seat of the soul is where the inner world and the outer world meet. Where they overlap, it is in every point of the overlap.
