Enneads IV.3: Psychological Questions
The Two Kinds of Memory Imply Two Kinds of Imagination
31. If memory belong to imagination, and if both the rational and irrational souls possess memory, we will have two kinds of imagination (intellectual and sensual); and if both souls are separate, each of them will possess one kind of imagination. The theory of two kinds of imagination within us in the same principle would not account for there being two kinds of imagination; and it would leave unsolved the question to which of them memory belongs. If memory belong to both kinds of imagination, there will always be two kinds of imagination—for it cannot be said that the memory of intelligible things belongs to the one, and that of sense-things to the other; otherwise we would have two animate beings with nothing in common. If then memory equally belong to both imaginations, what difference is there between them? Besides, why do we not notice this difference? Here is the cause.
OF THE TWO IMAGINATIONS ONE ALWAYS PREDOMINATES OR OVERSHADOWS THE OTHER.
When both kinds of imagination harmonize, they co-operate (in the production of a single act). The most powerful dominates, and only a single image is produced within us. The weaker follows the stronger, as the feeble reflection of a powerful light. On the contrary, when both kinds of imagination disagree and struggle, then only one of them manifests, and the other is entirely ignored, just as we always ignore that we have two souls; for both souls are melted into a single one, and the one serves as vehicle for the other. The one sees all, but preserves only certain memories when she leaves the body, and leaves in oblivion greater part of the things that relate to the other. Likewise, after we have established relations with friends of an inferior order, we may acquire more distinguished friendships, and we remember the former but very little, though we remember the latter very distinctly.
