Enneads IV.3: Psychological Questions
There Is a Timeless Memory Consisting of Self-consciousness
It (may be objected) that nothing hinders Intelligence from knowing the changes of other beings, such as, for instance, the periodical revolutions of the world, without itself undergoing any change. But then it would have to follow the changes of the moving object, as it would think first of one thing, and then of another. Besides, thought is something else than memory, and we must not apply to self-consciousness the name of memory. Indeed, intelligence does not busy itself with retaining its thoughts, and with hindering them from escaping; otherwise it might also fear lest it lose its own nature (“Being”). For the soul herself, remembering is not the same as recalling innate notions. When the soul has descended here below, she may possess these notions without thinking of them, especially if it be only recently that she entered into the body. The ancient philosophers seem to have applied the terms memory and reminiscence to the actualization by which the soul thinks of the entities she possesses; that (however) is a quite special kind of memory, entirely independent of time.
DEFINITION OF MEMORY DEPENDS ON WHETHER IT BELONGS TO THE SOUL OR ORGANISM.
But perhaps our solution seems superficial, and appears to rest on an insufficient analysis. It might indeed be asked whether memory and reminiscence, instead of belonging to the rational soul, might not characterize the lower soul, or the composite of soul and body that we call the organism? If indeed they belong to the lower soul, from where does the latter derive them, and how does she possess them? The same question may further be asked in the case of the organism. To answer all this, we shall, as said above, have to study our own interior principle to which memory belongs. If it be the soul that possesses memory, we shall have to ask what faculty or part thereof is constituted by memory. If, as has been urged by some, it be the organism to which memory belongs, and considering the organism as the sentient principle, how could this faculty operate within it? Besides, what is it that we should call the organism? Further, is it the same power that perceives sense-objects, and intelligible entities, or are there two distinct powers?
