What did all this further me, seeing it even hindered me? when, imagining whatever was, was comprehended under those often Predicaments, I essayed in such wise to understand, O my God, Thy wonderful and unchangeable Unity also, as if Thou also hadst been subjected to Thine own greatness or beauty; so that (as in bodies) they should exist in Thee, as their subject: whereas Thou Thyself art Thy greatness and beauty; but a body is not great or fair in that it is a body, seeing that, though it were less great or fair, it should notwithstanding be a body. But it was falsehood which of Thee I conceived, not truth, fictions of my misery, not the realities of Thy blessedness. For Thou hadst commanded, and it was done in me, that the earth should bring forth briars and thorns to me, and that in the sweat of my brows I should eat my bread.
And what did it profit me, that all the books I could procure of the so-called liberal arts, I, the vile slave of vile affections, read by myself, and understood? And I delighted in them, but knew not whence came all, that therein was true or certain. For I had my back to the light, and my face to the things enlightened; whence my face, with which I discerned the things enlightened, itself was not enlightened. Whatever was written, either on rhetoric, or logic, geometry, music, and arithmetic, by myself without much difficulty or any instructor, I understood, Thou knowest, O Lord my God; because both quickness of understanding, and acuteness in discerning, is Thy gift: yet did I not thence sacrifice to Thee. So then it served not to my use, but rather to my perdition, since I went about to get so good a portion of my substance into my own keeping; and I kept not my strength for Thee, but wandered from Thee into a far country, to spend it upon harlotries. For what profited me good abilities, not employed to good uses? For I felt not that those arts were attained with great difficulty, even by the studious and talented, until I attempted to explain them to such; when he most excelled in them who followed me not altogether slowly.
But what did this further me, imagining that Thou, O Lord God, the Truth, wert a vast and bright body, and I a fragment of that body? Perverseness too great! But such was I. Nor do I blush, O my God, to confess to Thee Thy mercies towards me, and to call upon Thee, who blushed not then to profess to men my blasphemies, and to bark against Thee. What profited me then my nimble wit in those sciences and all those most knotty volumes, unravelied by me, without aid from human instruction; seeing I erred so foully, and with such sacrilegious shamefulness, in the doctrine of piety? Or what hindrance was a far slower wit to Thy little ones, since they departed not far from Thee, that in the nest of Thy Church they might securely be fledged, and nourish the wings of charity, by the food of a sound faith. O Lord our God, under the shadow of Thy wings let us hope; protect us, and carry us. Thou wilt carry us both when little, and even to hoar hairs wilt Thou carry us; for our firmness, when it is Thou, then is it firmness; but when our own, it is infirmity. Our good ever lives with Thee; from which when we turn away, we are turned aside. Let us now, O Lord, return, that we may not be overturned, because with Thee our good lives without any decay, which good art Thou; nor need we fear, lest there be no place whither to return, because we fell from it: for through our absence, our mansion fell not -- Thy eternity.
