Plotinos: Complete Works, v. 2 In Chronological Order,...

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 souls152; 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.
