Quoted from: http://en.wikipedia.org/wiki/Jungian_archetypes
In later years Jung revised and broadened the concept of archetypes even further, conceiving of them as psycho-physical patterns existing in the universe, given specific expression by human consciousness and culture. Jung proposed that the archetype had a dual nature: it exists both in the psyche and in the world at large. He called this non-psychic aspect of the archetype the "psychoid" archetype.
He illustrated this by drawing on the analogy of the electromagnetic spectrum. The part of the spectrum which is visible to us corresponds to the conscious aspects of the archetype. The invisible infra-red end of the spectrum corresponds to the unconscious biological aspects of the archetype that merges with its chemical and physical conditions.[8] ...
The archetype was not merely a psychic entity, but more fundamentally, a bridge to matter in general.[9] Jung used the term unus mundus to describe the unitary reality which he believed underlay all manifest phenomena. He conceived archetypes to be the mediators of the unus mundus, organizing not only ideas in the psyche, but also the fundamental principles of matter and energy in the physical world.
It was this psychoid aspect of the archetype that so impressed Nobel laureate physicist Wolfgang Pauli. Embracing Jung's concept, Pauli believed that the archetype provided a link between physical events and the mind of the scientist who studied them. In doing so he echoed the position adopted by German astronomer Johannes Kepler. Thus the archetypes which ordered our perceptions and ideas are themselves the product of an objective order which transcends both the human mind and the external world.
I'm thinking that this last line could be cross-referenced with Steiner's views on the angelic "order" in addition to references to his early foundation work on "The Philosophy of Freedom" regrading "perceptions".
