AC 8279 - "Depth" and High"

AC 8279

The reason why "depth" denotes hell relatively to evil,
is that it is opposite to "high," by which is meant heaven,
and which is predicated of good.
Moreover evil corresponds to what is heavy on earth,
which sinks by its own weight;
thus also to the heaviness of a stone,
when by a "stone" is signified falsity.
