BOOK TEN
CHAPTER XV
23. Now whether all this is by means of images or not, who can rightly affirm? For I name a stone, I name the sun, and those things themselves are not present to my senses, but their images are present in my memory. I name some pain of the body, yet it is not present when there is no pain; yet if there were not some such image of it in my memory, I could not even speak of it, nor should I be able to distinguish it from pleasure. I name bodily health when I am sound in body, and the thing itself is indeed present in me. At the same time, unless there were some image of it in my memory, I could not possibly call to mind what the sound of this name signified. Nor would sick people know what was meant when health was named, unless the same image were preserved by the power of memory, even though the thing itself is absent from the body. I can name the numbers we use in counting, and it is not their images but themselves that are in my memory. I name the image of the sun, and this too is in my memory. For I do not recall the image of that image, but that image itself, for the image itself is present when I remember it. I name memory and I know what I name. But where do I know it, except in the memory itself? Is it also present to itself by its image, and not by itself?
