Full Idea
How could a spatial understanding understand anything? Wiil it do so with parts, seen as magnitudes or as points? If it is points, the understanding will never get through them all. If magnitudes, it will understand things an unlimited number of times.
Gist of Idea
Understanding is impossible, if it involves the understanding having parts

A Reaction
This seems to be a strong commitment to the idea that the mind is not physical because it is necessarily non-spatial.
