1. Chap. I.--Memory may be exercised independently of such images as are presented by the imagination.

I shall dispense with a formal preface, and to the subject on which you have for some time wished to hear my opinion I shall address myself at once; and this I do the more willingly, because the statement must take some time.

It seems to you that there can be no exercise of memory without images, or the apprehension of some objects presented by the imagination, which you have been pleased to call "phantasiae." For my part, I entertain a different opinion. In the first place, we must observe that the things which we remember are not always things which are passing away, but are for the most part things which are permanent. Wherefore, seeing that the function of memory is to retain hold of what belongs to time past, it is certain that it embraces on the one hand things which leave us, and on the other hand things from which we go away. When, for example, I remember my father, the object which memory recalls is one which has left me, and is now no more; but when I remember Carthage, the object is in this case one which still exists, and which I have left. In both cases, however, memory retains what belongs to past time. For I remember that man and this city, not by seeing them now, but by having seen them in the past.
