Steiner's name for the chalk-forming, de-animalizing force of the earth, whose arrested counterpart works in us as the polar partner of silica in shaping the head.
The lime process is Rudolf Steiner's term for the calcium-forming, chalk-building activity of the earth, which he described in his 1921 Dornach medical course as a process of de-animalization, the polar opposite of animal evolution. Its quietened counterpart works inside the human being as the partner of the silica process, helping to shape the physical head and to anchor the organism in earthly form.
The Lime Process in Anthroposophy is Rudolf Steiner's term for the calcium-forming or chalk-building activity that shapes the mineral earth and, in an arrested form, works within the human being. Steiner introduced it in his 1921 Dornach lecture course published as Anthroposophic Spiritual Science and Medical Therapy (GA 313). He called the geological building of limestone a de-animalization (Entanimalisierung), the polar opposite of animal evolution, just as slate-formation from silica is a de-vegetabilization. Within the human being, the lime process and the silica process work as polar partners, and it is chiefly through the head formation that we carry their opposites. The lime pole grounds the organism in earthly substance while silica opens it toward the cosmos. Anthroposophic physicians read calcium remedies through this polarity, treating illness as a disturbed relation between the two forces rather than a missing material.
In Steiner's Own Words
As human beings we live on the earth where there are silica processes and limestone processes. We would not be human beings if these processes permeated us. We are human beings through bearing within us the polar opposites of these processes. We are able to oppose the silica-formation process because we bear the opposite pole within us; we are able to oppose the limestone-formation process because we bear its polar opposite within us. It is chiefly owing to our head formation that we bear these poles within us, but the entire organism is also concerned, as I have described it in our breathing process, for example.
What it Means Today
The clearest living continuation of the lime process is the calcium pharmacy of anthroposophic medicine. When Steiner gave the GA 313 course in April 1921, the firm that became Weleda was being built up at Arlesheim in Switzerland and Schwäbisch Gmünd in Germany under Ita Wegman and the chemist Oskar Schmiedel, and calcium-bearing preparations soon entered its dispensary. The remedy Conchae, prepared from oyster shell, and Conchae cum Quercu, which combines that shell-calcium with oak bark, are textbook examples: both carry the de-animalized calcium-carbonate gesture Steiner had described, the shell being an animal substance returned almost wholly to mineral chalk. Clinicians at hospitals such as the Filderklinik near Stuttgart still reach for these preparations in children whose head and bone formation, the pole Steiner tied to lime, needs steadying.
Thalira synthesis: read this way, calcium in anthroposophic practice is never simply a building block to be topped up but a record of the earth letting go of life, so the lime process names the moment where former animal substance hardens into chalk and the same gesture, held in check, lends the human head its firm, earth-anchored form.
