Episode notes
Augustine Seeks A Trinitarian Analogy
- Augustine seeks a created analogy in the human mind to illuminate the Trinity rather than studying cognition for its own sake.
- This theological aim drives his discussion of the interior word and human understanding.
Augustine Contains Aristotelian Elements
- Sarah Byers argues Augustine integrated an Aristotelian element (agent intellect) via Plotinus and Marius Victorinus into his illumination theory.
- This suggests Augustine's scientia involves a 'divine light' enabling the soul to grasp intelligibility.
The Interior Word Born From Scientia
- Augustine describes an 'interior word' born from scientia that precedes linguistic signs and is spoken inwardly 'just as it is'.
- This interior speaking becomes the central analogy for the divine Word's generation.
