The Confessions: Chapter IX

Chapter IX.—Not Only Things, But Also Literature and Images, are Taken from the Memory, and are Brought Forth by the Act of Remembering.

16. And yet are not these all that the illimitable capacity of my memory retains. Here also is all that is apprehended of the liberal sciences, and not yet forgotten—removed as it were into an inner place, which is not a place; nor are they the images which are retained, but the things themselves. For what is literature, what skill in disputation, whatsoever I know of all the many kinds of questions there are, is so in my memory, as that I have not taken in the image and left the thing without, or that it should have sounded and passed away like a voice imprinted on the ear by that trace, whereby it might be recorded, as though it sounded when it no longer did so; or as an odour while it passes away, and vanishes into wind, affects the sense of smell, whence it conveys the image of itself into the memory, which we realize in recollecting; or like food, which assuredly in the belly hath now no taste, and yet hath a kind of taste in the memory, or like anything that is by touching felt by the body, and which even when removed from us is imagined by the memory. For these things themselves are not put into it, but the images of them only are caught up, with a marvellous quickness, and laid up, as it were, in most wonderful garners, and wonderfully brought forth when we remember.
