[1]“Yesterday, Asclepius, I delivered the perfect discourse, and now I think that it needs a sequel, an exposition of the discourse on sensation. Apparently, there is a difference between sensation and understanding, the former being material and the latter essential. To me, however, the two appear to be combined, not separate – in humans, I mean, for in other living things sensation is combined with the natural character, but in humans understanding is combined with it 〈as well〉.” (Mind differs from understanding as much as god differs from divinity. Divinity comes to be by god's agency, understanding by the agency of mind. Understanding is the sister of reasoned speech, or each is the other's instrument. There is no utterance of reasoned speech without understanding, nor is there evidence of understanding without reasoned speech.)

“Can understanding be understood without sensation, however, in the way that one pictures images when dreaming?”

“{It seems to me that in dream-vision both these faculties have been eliminated, although, when sleepers wake, 〈understanding〉 and sensation 〈are always combined.〉} At any rate, 〈sensation〉 is distributed to body and to soul, and, when both these parts of sensation are in harmony with one another, then there is an utterance of understanding, engendered by mind.”[…]
