Or just science, if you agree that fiction is a part of it, always was, and always will be as long as our brains are only miniscule fragments of the universe, much too small to hold all the facts of the world but not too idle to speculate about them.

Imagine the inside of St. Peter’s in Rome filled with a huge quantity of fibers around a millimeter in diameter that crisscross the building in every direction creating a firm mat – then you have an idea of what the brain looks like when magnified a thousand times.

It is actually impossible in theory to determine exactly what the hidden mechanism is without opening the box, since there are always many different mechanisms with identical behavior. Quite apart from this, analysis is more difficult than invention in the sense in which, generally, induction takes more time to perform than deduction: in induction one has to search for the way, whereas in deduction one follows a straightforward path.
