This third volume of Rudolf Steiner's Collected Works was originally his doctoral dissertation. Terse and to the point, it truly is a prelude to his later Philosophy of Freedom - indeed, one can sense an excitement of discovery that is absent in the latter work. This translation has been thoroughly reworked to make it conform to the late Ronald Brady's masterful introduction, which provides a line-by-line commentary.
