Steiner's teaching that Plato's four virtues transform across epochs, with wisdom becoming truth, courage becoming love, and temperance becoming practical judgment.
The Metamorphosis of the Virtues in Anthroposophy is Rudolf Steiner's teaching, given at Norrkoping in 1912 and published as GA 155, that the four Platonic virtues, wisdom, courage, temperance, and justice, transform across the post-Atlantean epochs and the three members of the human soul. Instinctive wisdom, the gift of the gods in the Egypto-Chaldean age, becomes conscious truthfulness in the Sentient Soul. Valour, the virtue of the Greeks and Romans, becomes love through the Christ-impulse working in the Intellectual Soul, the change Steiner saw in Francis of Assisi. Temperance becomes practical wisdom in the Consciousness Soul, and justice, for Plato the harmony of all virtues, ripens as the ideal of the sixth epoch. Each virtue, following Aristotle, is a living balance, the golden mean held by free inner effort between two destructive extremes such as recklessness and cowardice, or dullness and passion.
The Metamorphosis of the Virtues is Steiner's account of how the cardinal virtues of antiquity do not stand fixed but evolve. What Plato and Aristotle named wisdom, courage, temperance, and justice were once instinctive gifts. Across the ages they pass from the gods into human freedom, each one reborn as a deed the soul must now consciously achieve and balance for itself.
In Steiner's Own Words
What I have told you is a golden rule of the ancient mysteries. As so often, we find echoes of this mystery principle in the philosophers of antiquity, and we find in Aristotle, where he speaks of virtue, a statement that we cannot understand unless we know that what has now been said was an ancient mystery principle that Aristotle had received and incorporated into his philosophy. Hence Aristotle's remarkable definition of virtue, which is: Virtue is a human skill guided by rational insight, which, in relation to human beings, holds the middle ground between too much and too little.
What it Means Today
The idea that virtue is not a fixed rulebook but a balance the person must strike returned to academic philosophy through Alasdair MacIntyre's After Virtue, published in 1981. MacIntyre argued that modern ethics had lost the Aristotelian framework in which a virtue is a settled disposition, formed by practice, that aims at a flourishing life rather than at obedience to abstract law. His book launched the contemporary virtue-ethics movement, carried forward by philosophers such as Philippa Foot and Rosalind Hursthouse, and it rests on exactly the definition Steiner quotes from Aristotle: the virtue that holds the mean between too much and too little.
Steiner adds a dimension MacIntyre does not. For Steiner the mean is not static but historical. Thalira synthesis: where MacIntyre recovers Aristotle's balance as a timeless structure, Steiner reads that balance as a moving point, so that the courage prized by the Greeks must, in the age after the Mystery of Golgotha, be reborn as love, and the wisdom inspired in the Chaldeans must become a freely won truthfulness. Waldorf moral education applies this practically, treating each virtue as something a child grows into through imitation and habit rather than instruction, the disposition forming before the rule is ever stated.
