Between these two worlds intercourse is, _in the nature of things_, impossible.

But Man is not content that his state of godless isolation should endure for ever.

As a thinker, he has exiled God from Nature and therefore from his own daily life.
But, as a "living soul," he craves for reunion with God; and so long as the gulf between the two worlds remains impassable, his philosophy will be felt to be incomplete.

A supplementary theory of things must therefore be devised.

Corrupt and fallen as he is, Man cannot hope to climb to Heaven; but God, with whom nothing is impossible, can at his own good pleasure come down to earth.
