  Norris considers his Theories I and II to be the completion of Malebranche's project. In Theory I, Norris discusses the nature of God, and in Theory II he discusses how creation is related to God. The most substantial expansion upon Malebranche's thought occurs in the first part of this treatise, where Norris spends a great deal of time arguing that God is truth. The intelligible world is the mind of God, a “kind of Terra Incognita, a more Intellectual America” (3).
