Volume 8; Paragraph 440: "Archetypes, so far as we can observe and explain them at all, manifest themselves only through their ability to organize images and ideas, and this is always an unconscious process which cannot be detected until afterwards. By assimilating material whose provanance in the phenomenal world is not to be contested, they become visual and psychic."Volume 8; Paragraph 263-282: "Archetypes are typical modes of apprehension, and wherever we meet with uniform and regularly recurring modes of apprehension we are dealing with an archetype, no matter whether its mythological character is recognized or not."
"The collective unconscious consists of the sum of the instincts and their correlates, the archetypes. Just as everybody possesses instincts, so he also possesses a stock of archetypal images."
Volume 10; Paragraph 847: "The concept of the archetype ... is derived from the repeated observation that, for instance, the myths and fairy tales of world literature contain definite motifs which crop up everywhere. We meet these same motifs in the fantasies, dreams, deliria, and delusions of individuals living today. These typical images and associations are what I call archetypal ideas. The more vivid they are, the more they will be coloured by particularly strong feeling-tones ... They impress, influence, and fascinate us. They have their origin in the archetype, which in itself is an irrepresentable, unconscious, pre-existent form that seems to be part of the inherited structure of the psyche and can therefore manifest itself spontaneously anywhere, at any time. Because of its instinctual nature, the archetype underlies the feeling-toned complexes and shares their autonomy."
Volume 9i; Paragraph 155ff: "Again and again I encounter the mistaken notion that an archetype is determined in regard to to its content, in other words, that it is a kind of unconscious idea (if such an expression be admissible). It is necessary to point out once more that archetypes are not determined as regards their content, but only as regards their form and then only to a very limited degree. A primordial image is determined as to its content only when it has become conscious and is therefore filled out with the material of conscious experience. Its form, however... might perhaps be compared to the axial system of a crystal, which, as it were, performs the crystalline structure in the mother liquid, although it has no material existence of its own. This first appears according to the specific way in which the ions and molecules aggregate. The archetype in itself is empty and purely formal, nothing but a facultas praeformandi, a possibility of representation which is given a priori. The representations themselves are not inherited, only the forms, and in that respect they correspond in every way to the instincts, which are also determined in form only. The existence of the instincts can no more be proved than the existence of the archetypes, so long as they do not manifest themselves concretely."
