Steiner's name for the 869 Council of Constantinople ruling that struck the spirit from the human being, leaving only body and soul.
The Abolition of the Spirit in 869 in Anthroposophy is Rudolf Steiner's name for the decree of the Ecumenical Council of Constantinople of 869, which forbade Catholic scholarship to teach the trichotomy of body, soul, and spirit and left the human being as body and soul with certain spiritual qualities attached to the soul. Steiner set the term out in Stuttgart on 8 September 1919, in the lecture cycle published as Spiritual-Scientific Treatment of Social and Educational Questions, GA 192, and returned to it repeatedly across the same 1919 cycle. He treated the ruling not as a curiosity of church history but as the hidden root of later materialism: once the spirit was legislated out of the human picture, science was left with matter alone. Psychologists such as Wilhelm Wundt, Steiner said, are unwitting students of a ninth-century dogma, and Russian Leninism is that dogma carried to its most extreme political form.
The Abolition of the Spirit in 869 is Steiner's shorthand for a single act of church legislation with a very long shadow. At Constantinople the Catholic Church settled that man consists of body and soul, and that the soul merely carries some spiritual powers. Steiner argued that European thought has been working under that settlement ever since, in the pulpit, the laboratory, and the lecture hall.
In Steiner's Own Words
It was really more important than one might think that the Catholic Church abolished the spirit in 869 at the general council in Constantinople, which I have already mentioned several times. From that time on, it was not permitted within Catholic scholarship to speak of the human being having a spirit within him. It was only permitted to speak in a certain sense of man having a body and a soul. This was the case throughout the Middle Ages. And Catholic scholars in the Middle Ages feared nothing more than talking about trichotomy, that is, the threefold division of the human being into body, soul, and spirit. For the Council of Constantinople had determined: Man consists of body and soul, and the soul has certain spiritual powers and qualities; there is already some spirit in the soul, but one must not speak of a special spirit.
What it Means Today
Steiner named his own example, and it still holds. Wilhelm Wundt opened the Institute for Experimental Psychology at the University of Leipzig in 1879, the year usually given for the founding of psychology as a laboratory science. His Principles of Physiological Psychology of 1874 had already set the frame: a psychology built from sensation, reaction time, and physiological measurement, with the soul treated as the sum of inner processes rather than the dwelling of a spirit. Nothing in that programme announces itself as theological, and Steiner's point in the Stuttgart lecture is that it did not have to. The two-member picture was already the default of European scholarship, handed down from a ninth-century council, and Wundt received it as neutral method. The narrowing continued: John B. Watson's 1913 paper in Psychological Review, later known as the behaviorist manifesto, proposed dropping consciousness from the science altogether. Body and soul had become body and behaviour.
Thalira synthesis: a dogma that forbids a word does not stay inside the church that wrote it, it migrates into the vocabulary of whoever comes next, and by the time it reaches the laboratory nobody remembers it was ever a ruling. Read a modern psychology syllabus with 869 in mind and watch how often the third member is not argued away but simply never offered.
