An Analysis of Augustine's Porphyrian Critiques of Manichaeanism

One of the main shifts that is detectable in Augustine’s thinking involves a network of ideas connecting the nature and origin of evil, the nature of the human person, and the ultimate hope for humanity. These areas are tied together for Augustine and are particularly prominent in the writings pertaining to Manichaeanism. It has become clear in recent years that in relation to these areas of Augustine’s thought, it is important to consider the influence of Neo-Platonists like Plotinus and especially Porphyry. As I will explain, the analysis of certain critiques Augustine makes against the Manichaeans will enable us to gain a clearer sense of Porphyry’s influence on Augustine, as well as a better understanding of the ultimate position Augustine took on the several important metaphysical and soteriological issues.
