they have taught man that he is a hopeless misfit made of two elements, both symbols of death. 

A body without a soul is a corpse, a soul without a body is a ghost—

 yet search is there image of man’s nature: 

the battleground of a struggle between a corpse and a ghost 

a corpse endowed with some evil volition of its own 

and a ghost endowed with the knowledge that everything known to man is non-existent, 

that only the unknowable exists.
