2. Anthroposophy and Psychology

On the one hand, psychology looks at the mind and asks: What is the relation between this and the physical, the external and corporeal? In looking at the physical, on the other hand, and at what physical science has to say about it, some people—and in this respect psychology has a long history—believe that we must regard the mental as the really effective cause of the physical; others believe that we must regard the physical as the really empowering element, and the mental only as a kind of effect of it. The unsatisfactory nature of both views has been perceived by recent psychologists. They have therefore set up the curious theory of psycho-physical parallelism, according to which one cannot say that the body affects the mind or the mind the body, but only: corporeal processes are parallel to mental ones, and mental processes to bodily ones; one can only say what mental processes accompany the corporeal or what corporeal ones the mental.
