This section recalls the Manichean idea that the light of divinity is found in the human soul—yet, in a polemical move, Augustine finds the light of the God of the Bible and of Catholic teaching illuminating his soul, not that of any other being. What’s more, he doesn’t just find a truthful proposition, but a “Truth [that] had being,” suggesting that he has come to believe not because his questions have been spontaneously resolved, but because he has met and believed in
someone. As a result of this encounter in his soul, he finally understands, too, that evil as such doesn’t exist, because things only derive their being from a perfectly good Being; evil, in that sense, is a non-thing, an absence of good.
