Steiner's teaching that the inner organs form an unconscious planetary system inside the body, mirroring the outer cosmos and preparing the blood for the I.
Man's Inner Cosmic System in Anthroposophy is Rudolf Steiner's teaching, given in An Occult Physiology (GA 128, Prague 1911), that the human inner organs form an unconscious planetary system that mirrors the outer cosmos. Working through the physical body, under the ether-body and astral body, these organs meet the stream of nutrition with resistance: the spleen, liver, and gall-bladder strip incoming food of its own alien rhythm so that the blood can become the instrument of the I-Being. Steiner ties each organ to a planet of the macrocosm, naming the spleen a Saturn activity, the liver a Jupiter activity, the gall-bladder a Mars activity, the heart and blood the Sun, the lungs Mercury, and the kidneys Venus. The result is the macrocosm repeated inwardly, the great cosmos sounding again as a living organ-system within the human being.
Man's Inner Cosmic System is the title Rudolf Steiner gave to the fourth lecture of An Occult Physiology (GA 128), where he describes the inner organs as a hidden planetary order. Spleen, liver, and gall-bladder work in concert to transform food, the lungs and kidneys balance them against the air, and the heart stands at the centre as an inner Sun, all reflecting the cosmos outside.
In Steiner's Own Words
In occultism the activity of the spleen is characterised as a Saturn-activity, that of the liver as a Jupiter-activity, and that of the gall-bladder as a Mars-activity. On the same basis occult knowledge sees in the heart and the blood-system belonging to it something which merits the name Sun, just as the sun outside merits this name in the planetary system. In the lung-system there is contained what the occultists characterise as Mercury, and in the kidney-system that which merits the name Venus. Thus, by means of these names, we have pointed out in these systems of the human organism something like an inner world system.
What it Means Today
The organ-planet pairings Steiner set out in 1911 became working tools, not poetry, in the clinic he founded with Ita Wegman. At the Klinik Arlesheim near Basel, opened in 1921 as the Clinical-Therapeutic Institute, and in the joint medical text Fundamentals of Therapy (GA 27, 1925) that Steiner and Wegman wrote together, the liver was treated as the seat of Jupiter forces and the spleen as a Saturn organ, so that a sluggish liver could be approached through metals and plants associated with the same planetary signature. This is the basis on which Weleda, the anthroposophic pharmacy company founded in 1921, still formulates medicines today: a remedy is chosen so that its cosmic gesture meets the gesture of the affected organ.
Thalira synthesis: the inner cosmic system is the precise hinge of the macrocosm and microcosm idea, because it stops being a metaphor about the body resembling the sky and becomes a claim that the same seven planetary forces are physically at work, unconsciously, inside the digesting and breathing human being. A practitioner who accepts this reads an inflamed gall-bladder not only as a Mars organ out of balance but as a place where the cosmos itself has lost its inner equilibrium, and the work of healing becomes the work of restoring a small heaven.
