Enneads IV.6: Of Sensation and Memory
Cognition of Intelligible Objects Still Less Admits of an Impression
The cognition of intelligible things still less admits of an experience or impression; for the soul finds the intelligible things within herself, while it is outside of herself that she contemplates sense-objects. Consequently the soul's notions of intelligible entities are actualizations of a nature superior to those of sense-objects, being the actualizations of the soul herself, that is, spontaneous actualizations. We shall however have to relegate to another place[229] the question whether the soul sees herself as double, contemplating herself as another object, so to speak, and whether she sees intelligence as single in a manner such that both herself and intelligence seem but one.
