In Steiner's teaching, evil exists so that humanity, by overcoming it, gains the strength that raises good to holiness, a teleology he set out in 1906 (GA 95).
The Mission Of Evil in Anthroposophy is Rudolf Steiner's teaching that evil exists for a purpose within human evolution: the power a person must summon to overcome evil is the very power that raises good to the height of holiness. Steiner presented this teleology in Stuttgart in 1906, in the lecture cycle published as At the Gates of Spiritual Science (GA 95). There he taught that humanity carries good and evil within its karma and will one day thrust both out of itself, just as it once thrust out the animal kingdom, producing a future race evil by nature. Evil, he said, is the manure in which holiness ferments. The bearer of this work is the human I, schooled through the Manichaean stream, whose members train to transform evil into good. Modern psychology's research on post-traumatic growth studies a comparable arc from adversity to strength.
Steiner's answer to why evil is permitted at all is not a theodicy of excuses but a task. The Mission of Evil names the role evil plays in human evolution: it is the resistance against which the good must strengthen itself, the fermenting ground out of which holiness alone can grow, and the material a future humanity will learn to transform.
In Steiner's Own Words
The members of the Manichean Order are already learning how to transform quite radically those who by nature are wholly evil. And then the transformed evil will become a quite special good. The power to effect this change will bring about a condition of moral holiness on Earth. But this can be achieved only if the evil has first come into existence; then the power needed to overcome the evil will yield a power that can reach the heights of holiness. A field has to be treated with manure and the manure has to ferment in the soil; similarly, humanity needs the manure of evil in order to attain to the highest holiness. And herein lies the mission of evil.
What it Means Today
In 1995 the psychologists Richard Tedeschi and Lawrence Calhoun of the University of North Carolina at Charlotte coined the term posttraumatic growth, and in 1996 they published the Posttraumatic Growth Inventory in the Journal of Traumatic Stress to measure it. Their studies documented what clinicians had long noticed informally: a substantial share of people who struggle through severe adversity later report greater personal strength, deeper relationships, and a changed sense of what matters. Tedeschi and Calhoun are careful about the mechanism, and honesty requires repeating their caution. The growth does not come from the suffering itself but from the struggle with it, it is never guaranteed, and many people are simply harmed.
Steiner's 1906 lectures make a structurally similar claim at the scale of evolution rather than a single biography. He never romanticizes evil; the future race that practises evil consciously is described in GA 95 with open dread, and the Manichaean task of transforming it is called extremely difficult. What he insists on is that the capacity summoned in overcoming evil is real and new, and could arise no other way, as muscle strength arises only against load. Thalira synthesis: where the origin of evil asks what evil is made of, the mission of evil asks what evil is for, and Steiner's fermenting manure of holiness gives resistance the same generative role in world evolution that the struggle criterion in posttraumatic growth research gives it in one human life.
