Die philosophische Lehre des Platonismus 
Volume seven deals with Plato‹s theology, establishing the goal, center and as it were the keystone of theocentric Platonic philosophy. The following subjects are dealt with systematically: in the first volume of the set doxographical information on Plato‹s theology (182-183), Platonists‹ discussions of other theologies (184-187), Platonic definitions of the deity (188), the problem of recognizing and talking about God (189-192), characteristics of the gods (193-194), types or categories of gods (195-199), the highest God (200-204), place and dealings of the gods (205-206). The second volume of the set is linked to theology with a 'downward' spiral of intermediate beings (demons, nymphs, angels, heroes) (207-213). It concludes with the levels of soul (214-230) which are examined in their diverse forms and studied on the basis of the impact and their methods of approaching the divine.
