GA 151: Human and Cosmic Thought

Human and Cosmic Thought is a compact cycle of four lectures Rudolf Steiner gave in Berlin from 20 to 23 January 1914, during the General Meeting of the Anthroposophical Society. Across these four sittings he pursues a single, daring question: why do thoughtful people, each one sincere and each one able to defend a position, arrive at such irreconcilable pictures of the world. His answer is not that one camp is right and the rest mistaken. It is that the human mind moves through a spiritual sky much as a planet moves through the zodiac, and that the great philosophical positions are lawful, recurring stations within that sky. The cycle is, in effect, a map of how world-views are born, and a quiet plea for the breadth of soul that can hold many of them at once.

Place in Steiner's Work

This volume belongs to a fertile middle period, the years in which Steiner was building Anthroposophy as a discipline rather than a creed. It stands close to his early theory of knowledge, where thinking itself is treated as a spiritual organ of perception, and it carries that earlier work forward into a full cosmology of the mind. Readers who know Philosophy of Freedom will recognise the conviction that thought is the one region of reality we inhabit from within, the one place where we are present in every fibre of what we make. Here that conviction is widened into a survey of every possible standpoint, so the cycle reads as a bridge between Steiner the philosopher and Steiner the seer.

It is worth noting how unusual the gesture is. Most thinkers, having found a position they trust, spend their energy defending it against rivals. Steiner does the opposite. He stands back far enough to see that the rivals belong together, that they form a single ordered whole, and that the quarrel between them is a sign of partial vision rather than of error. The cycle therefore sits among his works of method, alongside his guidance on inner development and his studies of the human senses. It also anticipates his later teaching on cosmic rhythm, where the same instinct returns again and again: an inner faculty answered by a pattern in the heavens, the small human circle echoing the great cosmic one.

Themes and Structure

The first lecture clears the ground, and it does so with a provocation. Steiner argues that most people do not truly think at all; they move words about, mistaking the familiar ring of a term for genuine understanding. Real thinking, he says, means setting a concept into motion. He offers the image of a triangle whose sides are allowed to slide and turn at varying speeds, so that acute, right-angled, and obtuse forms all flow from one living movement. Only such mobile thinking lays hold of the general idea behind the single instances. This mobile thinking is the instrument the whole cycle requires, and it is the quiet thesis beneath everything that follows: a mind that has learned to move can grasp truths that a fixed mind must reject as mere words.

The second lecture asks why even professional thinkers fall into confusion, why questions about universals and about Kant's hundred coins can puzzle clever minds for centuries. The cause, Steiner suggests, is one-sidedness. An individual, an epoch, a whole culture leans toward a single way of seeing, lets it harden into the only way, and then works that bias back upon everyone who lives within it. The remedy is not a new doctrine but a new flexibility, the willingness to enter standpoints not one's own.

The third lecture unfolds the scheme for which the cycle is best remembered. Steiner names twelve standpoints that a mind can take toward reality, and arranges them in a circle that mirrors the zodiac: Materialism, Sensationalism, Phenomenalism, Realism, Dynamism, Monadism, Spiritualism, Pneumatism, Psychism, Idealism, Rationalism, and Mathematism. Each is genuinely valid within its own domain; each becomes a distortion only when it claims to be the whole. A soul is drawn to one of these stations, Steiner proposes, not because it has proved its case but because the soul is so disposed that it stands open to be illuminated by that particular sign, the way the earth receives a different influence when a planet shines from Aries than when it shines from Leo.

Onto this fixed circle he then sets seven moving moods, which behave like planets crossing the zodiac. These are Gnosis, Logism, Voluntarism, Empiricism, Mysticism, Transcendentalism, and Occultism. A mood is a temper of the inner life, a characteristic way of laying hold of the world, and it can pass through any of the twelve signs. As Steiner puts the principle, "Gnosis is a planet which passes through all the mental-constellations." A thinker is therefore rarely a pure type. Far more often a mood stands within a sign, as Schopenhauer's will-driven temper stood within the constellation of Psychism, or as Hegel's logical temper stood within Idealism. Steiner draws the correspondences with care, pairing Gnosis with Saturn, Logism with Jupiter, Voluntarism with Mars, Empiricism with the Sun, Mysticism with Venus, Transcendentalism with Mercury, and Occultism with the Moon.

He then adds a third layer, three tones that colour any combination: theism, intuitionism, and naturalism, answering to Sun, Moon, and Earth, with a final human standpoint he calls anthropomorphism. The arithmetic he offers is itself a teaching. Twelve signs and seven moods, joined to the three tones and the one human centre, yield a spiritual cosmos of twenty-three legitimate world-conceptions, each with its rightful place, none of them the last word. The picture is meant to widen the heart as much as the head, to leave the reader with a sense of how vast and varied the field of human seeing truly is.

The fourth lecture turns the scheme to use. Steiner shows how a real philosopher can be read as a constellation, a mood occupying a sign, and how exercises can let a student feel each mood in turn rather than remaining captive to one. The closing moral is plain. The purpose of all this is not to label others but to practise breadth, to taste the truth-value of each standpoint from within rather than to win a quarrel. Spiritual Science, he suggests, is called to be a peacemaker among world-views, precisely because it can show why each one was bound to arise and where each one rightly belongs.

If this map of the thinking mind drew you in, several paths open from here, each a way of going deeper rather than wider.

  • The roots of free thinking. Steiner's earlier Philosophy of Freedom grounds the claim that thought is a spiritual deed, the seed from which this cycle grows.
