# Cusanus and the Three Stages of Mystical Knowledge

## GA 51 — 12 November 1904, Berlin

### Lecture III

Today we come to a high point of medieval mysticism, to the mystic who was at the same time one of the most important scholars of his time: Nikolaus Chrypff or Krebs, of Kues on the Moselle, called the Cusanian. He was one of the most interesting personalities of his time. He lived from 1401 to 1464. He was at the height of his time in the various sciences. He was a mathematician, physicist, jurist, first lawyer. He was also one of the leading, the tone-setting men of his time. He was extraordinarily ahead of his time. About a hundred years later, Nicolaus Copernicus put the worldview of astronomy on a new footing. But Nicolaus of Cusa had already clearly stated that the earth moves around the sun. Even more significant seems to be that the Cusan was not only a deep, leading thinker, but a clear thinker. He is a thinker who had absorbed scholasticism completely, That which is expressed by scholasticism is studied very little. The tremendous clarity and sharpness of conceptualization is the essential thing about it. Never has there been such a sharp guidance of the conceptual contours, never such a strict limitation of the concepts related to the spiritual life. Whoever wants to train himself in clear thinking, whoever works with firm, conceptual outlines, would have to immerse himself in one of the scholastic works. Cusanus underwent this training.

He also possessed everything related to the social knowledge of his time. He had a comprehensive circle of vision. In 1432, at the Council of Basel, he took an important position. Then he made long journeys through Germany and the Netherlands, dedicated especially to the reform of education. He emerged from the school of the "Brothers of Common Life". There, the focus was on a thorough formation of the mind and a clear education of the intellect. The Cusanian undertook his journey in the service of this school. Scientifically trained, clear and sharp thinking - he stands there freely, as a personality of impressive character. If he had wanted to, he could have achieved many things in the scientific field. As a preacher he knew how to grasp the listeners in the depth of their minds through his sermon. That which made his preaching so significant was the stream that emerged from medieval mysticism, the stream that we find in Eckhart, in Tauler and Suso, and in another guise in Giordano Bruno and Paracelsus.

Deepness of mind, fire of soul, was paired in him with a quite transparent, sharp conceptual faculty. Everything that the mind can grasp, that reason can survey, gave the Cusanian only the substructure for what he had to say to the world. He was sent by the Pope to Constantinople to bring about a union between the Greek and Roman Churches. On his way home, he had an epiphany in which he felt that there was something else besides the knowledge of the intellect. From then on, he attributed the highest value only to that which is higher than knowledge. He wrote the work: “De docta ignorantia” out of this mood. The title: "Of the learned ignorance" should mean: something that goes beyond the mere sensory and intellectual knowledge, a seeing, a being enlightened. If one wants to understand this completely, one has to take some terms to help, which only the 19th century brought.

The 19th century has developed a peculiar physiology of the senses, for example in the famous Law of the Energies of the Senses by the physiologist Johannes Müller. He says that we can see a color, take in light, this stems from the fact that our eye is built in a certain way. If we did not have the eye, the world shining in light and colors would be lightless, without the perception of colors. The same can be said about the arrangement of our ear. It depends on the arrangement of our senses how the external world penetrates into us. It depends on the specific energies of our senses how we perceive the world. Helmholtz has spoken about how he thinks of the relationship. He says: How can I know how the light in itself, the sound in itself is formed? Only signs of the external world are our sensory perceptions.

The Cusanian calls "knowledge" also in this sense knowledge, namely as the impressions processed by the mind.

We now ask: Do not our senses have an intimate relation to what we see, hear, and so on? We have to imagine that the eye itself is built by light, that the senses are not only there for the outside world, but from the outside world. The eye has been formed by the light. Who are the ones who build our senses? If man were not limited within the limits of his ordinary consciousness, he would know this.

In the single individual must be the force which forms the senses. In embryonic life the light must be effective, the sound must be effective. They must work in embryonic life in the individual himself and form the organs. The light closes the eye from within, the sound the ear. We perceive the external qualities only through the senses. The senses have also formed these external qualities. They are the builders of our own organs. We ourselves are light from the world-light; we are sound from the world-sound.

The mystic lives himself into that which lives and weaves around him and in him. The creating light, which works outside and creates inside, he feels. He is himself shining and sounding in a shining and sounding world. When he lives in the creative light, lives in the creative sound, then he has mystical life. Then something comes over man that is different from the light from outside and the sound from outside. Whoever has experienced this once, feels it as truth. The Gnostics, the Egyptian mystics, the mystics of the Middle Ages speak of the creating light. They call it the aeon light. It is a light which from the mystic awakens the objects around him to living life. This is the pleroma of the Gnostics. Thus, the mystic feels blessed in the world light. He feels blissfully interwoven with this aeon light. There he is not separated from the essence of things; there he is partaker of the immediate creative power. This is what the mystic calls his bliss in the creative light. The Vedanta wisdom calls the world wisdom Chit, but the bliss where the mystic is immersed in the things, where the soul merges completely with the things, is called Anânda. Chit is world wisdom, Anânda is the wisdom that merges directly with the aeon light, that feels one with the all-light shining through the world. This mood the Cusanian calls “docta ignorantia.”

Just as man can have the experience of merging with the Aeon Light into the Pleroma, so he can also merge with the cosmic world-thought. Then he feels the world thoughts resounding in his own inner being. When man becomes aware of the thought that brings the law to existence in things, and feels this swelling up in him as his own law, then the things resound in their own essence in his soul, that he becomes intimate with the things, as the friend becomes intimate with the friend. This perception of the whole world the Pythagoreans called harmony of the spheres. This is the resounding of the essence of things in man's own soul. There he feels united with the power of God. That is the hearing of the harmony of the spheres, of the creating universal law; that is being interwoven with the being of things, that is where the things themselves speak, and the things speak through the language of his soul out of himself. Then he has attained what the Cusanian says no words are capable of expressing.

The being is the seen. This does not express the sublime existence which comes as a predicate to things when the mystic unites himself in the deepest way with things. This sublime existence is the sat of the Indians.

The Pythagorean school distinguishes three stages: First, the external perception = Chitz second, the Pleroma = Anânda; third, the harmony of the spheres = Sat.

The Pythagorean school distinguishes three stages.

These are the three stages of cognition in the Cusanus: first, knowledge; second, super-knowledge or beatification; third, deification. Thus he calls them in the "Docta ignorantia."

That he knows these states gives his writings a mellowness, a softness, that one may say they are perfectly sweet with maturity. Moreover, his writings are wonderfully clear, transparent, full of tremendous ideas.

He was a leading spirit. All who follow him then stand on the foundation he laid. So also Giordano Bruno. Cusanus drew his wisdom from the Pythagorean school. He understood what was meant by the Pleroma, the Aeon Light and the Harmony of the Spheres. - Ruysbroek and Suso are also the precursors of Cusanus in their refined and spiritually drunken way.

The *Theologia Deutsch* is like an overture to what the Cusanian wrote. A reprint of it has been procured by Franz Pfeiffer after a manuscript of 1497. Deep, cozy tones of a historically unknown personality are contained in this writing. If someone wants to understand the Sat of Vedanta philosophy, he must, as in Anânda he must pour himself out into the world, in Sat he must pour out his will completely. In the deification (Sat) the selfless will must be there; his will must have become impersonal. - The one who wrote the *Theologia Deutsch* made sure that his name did not come down to posterity. He calls himself only “the Frankfurter”. Man must surrender his will to the Divine, as a messenger of the Godhead, and that which man wills of himself he calls Scripture, an offering.

Before Cusanus, mysticism strove from mere knowledge into the introduction into the pleroma, the creating world-light. Then in the learned not-knowing this came out in a learned and perceptive way. Knowledge and understanding were awakened to immediate, new life.

The Kusanian's not-knowing is at the same time a super-knowing. He distinguishes three stages: Knowledge, Beatification, Deification - Chit, Anânda, Sat. He is at the same time the greatest scholar and one of the deepest human beings.
