10.16.25   Lord, I, truly, toil therein, yea and toil in myself; I am become a heavy soil requiring over much sweat of the brow. For we are not now searching out the regions of heaven, or measuring the distances of the stars, or enquiring the balancings of the earth. It is I myself who remember, I the mind. It is not so wonderful, if what I myself am not, be far from me. But what is nearer to me than myself? And to, the force of mine own memory is not understood by me; though I cannot so much as name myself without it. For what shall I say, when it is clear to me that I remember forgetfulness? Shall I say that that is not in my memory, which I remember? or shall I say that forgetfulness is for this purpose in my memory, that I might not forget? Both were most absurd. What third way is there? How can I say that the image of forgetfulness is retained by my memory, not forgetfulness itself, when I remember it? How could I say this either, seeing that when the image of any thing is impressed on the memory, the thing itself must needs be first present, whence that image may be impressed? For thus do I remember Carthage, thus all places where I have been, thus men's faces whom I have seen, and things reported by the other senses; thus the health or sickness of the body. For when these things were present, my memory received from them images, which being present with me, I might look on and bring back in my mind, when I remembered them in their absence. If then this forgetfulness is retained in the memory through its image, not through itself, then plainly itself was once present, that its image might be taken. But when it was present, how did it write its image in the memory, seeing that forgetfulness by its presence effaces even what it finds already noted? And yet, in whatever way, although that way be past conceiving and explaining, yet certain am I that I remember forgetfulness itself also, whereby what we remember is effaced.
