Full Idea
Those who decide in favour of the subsistence of the absolute reality of space and time must assume two eternal and infinite self-subsisting non-entities which exist (without there being anything real) only to comprehend everything real within themselves.
Gist of Idea
If space and time exist absolutely, we must assume the existence of two pointless non-entities
