ABSTRACT
This chapter discusses Augustine's life as a "secular" Catholic theologian and philosopher. It explains one of the most profound developments in his theology of the Holy Spirit. In the writings of 389-391, Augustine assigns to the Spirit a distinct place within the economy of creation that subsumes and elucidates his burgeoning love-pneumatology and beckons us even deeper into the mystery of the Spirit eternal. The chapter describes that pneumatological principle emerges in concert with a most consequential development in Augustine's thinking on the analogical nature of created things. Such rigorous philosophical discourse, however, was to wane in the aftermath of Augustine's visit to Hippo in the winter. Even in the Thagastan writings, some scholars detect a diminishment in Augustine's enthusiasm for the liberal arts and, conversely, a heightened concern for matters ecclesial and dogmatic. In the Roman writings and especially in the Thagastan writings, he increasingly uses forma alongside species.
