Steiner's teaching that the task of art is to build a bridge between the earthly world and the spiritual world.
The Arts and Their Mission is the title Rudolf Steiner gave to a 1923 lecture cycle in Dornach, and the phrase has come to name his whole view of why art exists. Art, for him, is no decoration added to life. It has a serious office: to carry the life of the spirit into earthly form, so that stone, colour, word and tone reveal what lies beyond the senses.
The Arts and Their Mission in Anthroposophy is Rudolf Steiner's account, given in the 1923 Dornach lecture cycle of that name (GA 276), of why art exists and what it is for. Where ordinary knowledge stops at a closed door, and where religion alone cannot cross it, art forms a bridge across the abyss between the earthly world and the spiritual world. Each art, in its own substance, carries spiritual life into earthly form: architecture into space, sculpture into the modelled body, painting into colour, poetry into the word, music and eurythmy into tone and movement. Art so understood stands beside cognition and religious life as a third serious path to the spirit, and its renewal out of living spiritual perception was the working task of the Goetheanum.
In Steiner's Own Words
It is here that art enters. It forms a bridge across the abyss. That is why art must realize that its task is to carry the spiritual-divine life into the earthly; to fashion the latter in such a way that its forms, colors, words, tones, act as a revelation of the world beyond. Whether art takes on an idealistic or realistic coloring is of no importance. What it needs is a relationship to the truly, not merely thought-out, spiritual. No artist could create in his medium if there were not alive in him impulses springing from the spiritual world. This fact points to the seriousness of art, standing alongside the seriousness of cognition and religious experience.
What it Means Today
When Steiner spoke these lectures in the summer of 1923, the cultivated phrase of the hour was l'art pour l'art, art for art's own sake, the doctrine that a poem or a painting answers to nothing outside itself. He set his whole cycle against it. Art, he held, had drifted into being treated as a luxury hung at the edge of life, and the cure was not more theory but a renewal of the arts out of direct spiritual perception. That renewal was not an idea he left on the page. It was already standing in wood and concrete on the hill above Dornach.
The first Goetheanum, and the second that replaced it after the fire of 1922, were built as the proof of the claim. The same impulse produced eurythmy, the movement-art Steiner had begun in 1912, and Marie Steiner-von Sivers' renewal of recitation, so that speech and gesture could again show the spirit at work. This is the lineage a visitor still meets at the Goetheanum School of Spiritual Science: a school of painting that works out of the colour itself, a stage where tone is made visible in moving form, a building whose pillars metamorphose rather than repeat. The argument of 1923 is that each separate art, kept honest to its own material, becomes one span of a single bridge, and that the artist who has lost the spiritual world has nothing left to carry across it. The arts and their mission find their historical proof in the mission of art across the ages.
