Crazy people do not apply the principle of scientific parsimony... they shoot for the baroque.

It is sometimes an appropriate response to reality to go insane.

Once, in a cheap science fiction novel, Fat had come across a perfect description of the Black Iron Prison, but set in the far future. So if you superimposed the past (ancient Rome) over the present (California in the twentieth century) and superimposed the far future world of The Android Cried Me a River over that, you got the Empire, as the supra- or trans-temporal constant. Everyone who had ever lived was literally surrounded by the iron walls of the prison; they were all inside it and none of them knew it.

Fat realized that one of two possibilities existed and only two; either Dr. Stone was totally insane – not just insane but totally so – or else in an artful, professional fashion he had gotten Fat to talk; he had drawn Fat out and now knew that Fat was totally insane.
