Query: It is the essence, the heart, of brilliance and genius.

By the end of this novel ( I can't even believe it's a novel ) I was breathless. The word " genius" has become mundane, but I find no other word that can describe a fraction of Conrad's writing in Heart of Darkness. I thought this novel would be boring and dense, and instead it turned out to be the most amazing book I have yet read. It endeavors so much and completes it so " eloquently." Marlow is what everyman should become at some point, and Kurtz--what can describe Kurtz? He is the phantom, the divinity of some other world. Even if this novel was read on a superficial surface; the descriptions and narrative are explosive and paint a picture that one can almost touch. It's hard to think that this was all in words and is held by two covers..because it is like holding burning dynamite. I'm going to be reading this many more times and for many more years to come. Because how many more ways can I interpret " the horror, the horror"?
