5.10.19   But now despairing to make proficiency in that false doctrine, even those things (with which if I should find no better, I had resolved to rest contented) I now held more laxly and carelessly. For there half arose a thought in me that those philosophers, whom they call Academics, were wiser than the rest, for that they held men ought to doubt everything, and laid down that no truth can be comprehended by man: for so, not then understanding even their meaning, I also was clearly convinced that they thought, as they are commonly reported. Yet did I freely and openly discourage that host of mine from that over-confidence which I perceived him to have in those fables, which the books of Manichaeus are full of. Yet I lived in more familiar friendship with them, than with others who were not of this heresy. Nor did I maintain it with my ancient eagerness; still my intimacy with that sect (Rome secretly harbouring many of them) made me slower to seek any other way: especially since I despaired of finding the truth, from which they had turned me aside, in Thy Church, O Lord of heaven and earth, Creator of all things visible and invisible: and it seemed to me very unseemly to believe Thee to have the shape of human flesh, and to be bounded by the bodily lineaments of our members. And because, when I wished to think on my God, I knew not what to think of, but a mass of bodies (for what was not such did not seem to me to be anything), this was the greatest, and almost only cause of my inevitable error.
