I merely remark here on the fact that both cases have the same kind of completeness and the same kind of incompleteness.

You can explain a man's detention at Hanwell by an indifferent public by saying that it is the crucifixion of a god of whom the world is not worthy.

The explanation does explain.

Similarly you may explain the order in the universe by saying that all things, even the souls of men, are leaves inevitably unfolding on an utterly unconscious tree--the blind destiny of matter.

The explanation does explain, though not, of course, so completely as the madman's.
