D. Dark and brooding realities of life

This is because his poems are usually about death or mourning or something of this sort. He doesn't really have any ideas of the western world nor the natural world, and if you look at his poems he doesn't really talk about a new nation. You can see this in some poem like The Cask of Amontillado
