Abstract

This article argues that the analogical argument employed by Augustine in De Trinitate (the soul-God analogy) is formally identical to the analogical argument employed by Plato in the Republic (the city-soul analogy). The similarities between these two analogies, however, have received insufficient attention in the secondary literature. My goal is to fill this lacuna. I first provide a summary of the analogical methodology of these two works, and I then proceed to translate these two analogies into one analogical argument form, showing that they are formally equivalent. I then differentiate these two analogies from other analogical arguments by focusing on their exploratory and programmatic character. This differentiation helps to capture the uniqueness of these two analogies, to understand their function, and, ultimately, to appreciate more fully the consonance between Augustine’s methodology and Plato’s.
