So far in Joseph Conrad’s “Heart of Darkness”, we as readers are still left to speculate what “darkness” is referred to in the title of the book. There is no lack of the word itself; however darkness and somber tones are used throughout the book to describe an entire range of objects and concepts, leaving us unsure of which usage of the term is the important one.
Darkness can be found in the wool of the old women in Brussels, in the skin color of the slaves, in the night, in the undergrowth of the Jungle trees at night and all around [...] Kurtz. [...] darkness is omnipresent through the tone of the narration, linking these separate themes together.[...] there is a certain passivity and restraint to the character’s (Marlow’s) tone and actions in the face of such animated events. [examples]. This passivity of character is also accompanied by the length of time in this book; [...]. Through this dark narration, all the dark attributes of the Congo seem to blur together into a single overhanging gloom that is ever present. These elements are never as closely brought together as when Marlow questions: “What was in [the wall of matted vegetation]? I could see a little ivory coming out of there, and I had heard Mr. Kurtz was in there.” (p.32)
The darkness could also be interpreted as the absurdity that is ever present: the lack of clear goals and directions, the absurd shelling of the continent by the ship; the blind leading the blind, or more precisely the blind leading themselves. [...]. These incoherencies further reinforce [...] the “overall darkness” of the book.
Therefore, it is my opinion that darkness in this book is not brought in by a single defined dark entity but by a collection of dark subjects, situations, places and people which together form the Congo. [...].
