You would allow, I said, that there is in nature an upper and lower and middle region?

Illustrations of the unreality of certain pleasures. And if a person were to go from the lower to the middle region, would he not imagine that he is going up; and he who is standing in the middle and sees whence he has come, would imagine that he is already in the upper region, if he has never seen the true upper world?
To be sure, he said; how can he think otherwise?
[E] But if he were taken back again he would imagine, and truly imagine, that he was descending?
No doubt.
All that would arise out of his ignorance of the true upper and middle and lower regions?
