Lecture IV
Our brain could not be worked upon by our daily life if our whole organism were not so prepared that it provides a basis for this daily work. And this work of preparation comes from the cosmos. Thus as we work daily at the “engraving” of the brain, which makes it into a mirror-apparatus for our daily thought, so, in so far as we cannot ourselves do this engraving, this giving form, form has to be given to us from the cosmos. As our little thoughts work and make their little engravings, so must our whole organism be built up from out of the cosmos, according to the same pattern of thought-activity. For example, that which appears to us finally in the sign of Idealism is present in the spiritual cosmos as the activity producing Idealism, and it can so work upon a man that it prepares his whole organism so that he inclines to Idealism. In like manner are the other varieties of moods and signs worked in upon men from out of the spiritual cosmos.
