Anthroposophy and the Riddle of the Soul
Now let us assume that I remember something in an arbitrary way, then it happens in such a way that I unfold this will out of a certain series of images. The development of the will is in turn connected with a breakdown, if external impressions do not now penetrate again, and the fact that these do not come is ensured by the development of the will, which is a breakdown. And this dismantling allows that which is in the subsoil to emerge as a sculpture of the human being when the memory is voluntarily recalled. If free-rising images come up, it happens the other way around. There is some external impression present that forms into a thought. The thought is vividly active. It is imprinted on the brain. This plastic activity is similar to the plastic activity that once developed in the substrate that which can live in the substrate in a certain form. This lives in the plastic activity that the thought has now formed.
