Augustine of Hippo · On the Soul and its Origin
Book IV · Chapter 8 — We Have No Memory of Our Creation.
And whosoever shall have attempted to fathom such knowledge may not improperly have addressed to him the words we have before quoted, "Seek not out the things that are too high for thee, neither search the things that are above thy strength." Now it is not a question of mere altitude, such as is beyond our stature, but it is an elevation which our intelligence cannot reach, and a strength which our mental power cannot cope with. And yet it is neither the heaven of heavens, nor the measure of the stars, nor the scope of sea and land, nor the nethermost hell; it is our own selves that we are incapable of comprehending; it is our own selves, who, in our too great height and strength, transcend the humble limits of our own knowledge; it is our own selves, whom we are incapable of embracing, although we are certainly not beside ourselves. But we are not to be compared with cattle simply because we do not perfectly discover what we ourselves are: and yet you think that we deserve the humiliating comparison, if we have forgotten what we were, even though we knew it once. My soul is not now being derived from my parents, is not now receiving insufflation from God. Whichever of these two processes He used, He used when He created me; He is not at this moment using it of me, or within me. It is past and gone,--not a present thing, nor a recent one to me. I do not even know whether I was aware of it and then forgot it; or whether I was unable, even at the time when it was done, to feel and to know it.
Chapter 9 [VII.]--Our Ignorance of Ourselves Illustrated by the Remarkable Memory of One Simplicius.
Observe now, while we are, while we live, while we know that we live, while we are certain that we possess memory, understanding, and will; who boast of ourselves as having a great knowledge of our own nature;--observe, I say, how entirely ignorant we are of what avail to us is our memory, or our understanding, or our will. A certain man who from his youth has been a friend of mine, named Simplicius, is a person of accurate and astonishing memory. I once asked him to tell me what were the last lines but one of all the books of Virgil; he immediately answered my question without the least hesitation, and with perfect accuracy. I then asked him to repeat the preceding lines; he did so. And I really believe that he could have repeated Virgil line after line backward. For wherever I wished, I made trial whether he could do it, and he did it. Similarly in prose, from any of Cicero's orations, which he had learnt by heart, he would perform a similar feat at our request, by reciting backwards as far as we wished. Upon our expressing astonishment, he called God to witness that he had no idea of this ability of his previous to that trial. So far, therefore, as memory is concerned, his mind only then learnt its own power; and such discovery would at no time be possible except by trial and experiment. Moreover, he was of course the very same man before he tried his powers; how was it, then, that he was ignorant of himself?
