As regards the uncertainty about everything which Varro alleges to be the differentiating characteristic of the New Academy, the city of God thoroughly detests such doubt as madness. Regarding matters which it grasps by the mind and reason it has most absolute certainty, although its knowledge is limited because of the corruptible body pressing down the mind,⁠a for, as the apostle says, “We know in part.” 1 Corinthians 13:9 It believes also the evidence of the senses which the mind uses with the aid of the body; for [if one who trusts his senses is sometimes deceived], the one who imagines he should never trust them is more wretchedly deceived. It believes also the Holy Scriptures, old and new, which we call canonical, and which are the source of the faith by which the just lives Habakkuk 2:4 and by which we walk without doubting while we are absent from the Lord. 2 Corinthians 5:6 As long as this faith remains inviolate and firm, we may without blame entertain doubts regarding some things which we have neither perceived by sense nor by reason, and which have not been revealed to us by the canonical Scriptures, nor come to our knowledge through witnesses whom it is absurd to disbelieve.
