Lecture I
In an abstract way many people already speak about all kinds of polarities in the human being. Mystical, nebulous publications discuss all kinds of positive and negative influences in man. They shy away from ascending to a much more concrete, more spiritual, but spiritually entirely concrete plane, and so they speak in a manner about the human being's positive and negative polarities which is just as abstract as that in which they discuss polarities in inorganic nature. Real knowledge of the human being can only come about if we rise above the poverty-stricken concepts of positive and negative, the poverty-stricken concepts of polarity as found in inorganic nature, and ascend to the meaningful concepts of luciferic and ahrimanic influences in man.
