Grendel follows the philosophical evolution, from solipsism to nihilism, of a socially isolated creature, a monster. It is an examination of human supernatural curiosity and its many dangers, specifically the tendency toward blind cynicism. Grendel is a censure of the rapid growth of this cynicism in twentieth century society and the consequent widespread distrust of abstract ideals. In investigating his own nature, the monster in the story destroys himself. He realizes that the universe is determined, accidental, and so he loses faith in his own importance. With time, he becomes a beast, until eventually his soul has wholly left him. He does not die for love, or for passion, or for freedom.

As a philosophy, nihilism is complete. It provides an answer to every metaphysical why?. Whatever the concern, a nihilist can conclusively state, There is no way to truly know, but it does not mat...
