"Hegel made famous his aphorism that all the rational is real and all the real rational; but there are many of us who, unconvinced by Hegel, continue to believe that the real, the really real, is irrational, that reason builds upon irrationalities. Hegel, a great framer of definitions, attempted with definitions to reconstruct the universe, like that artillery sergeant who said that cannon were made by taking a hole and enclosing it with steel."
