Modernist writers of the 20th century completely changed literature. Rather than putting the main focus of storytelling on the story itself, they are a step further by basing their novels on the concept of truth and their own understanding. They explored the idea of inner conflict in consciousness, alienation, thinking and asked the readers important questions in testing the soul boundary. For example, Henry James is interested in the thought act itself, and his work is done primarily in the head of his personality.
The two main themes of "heart of darkness" are the contradiction between "reality" and "darkness", and the concept of suppression and whether it is necessary or not. Conrad's article explaining about the control of starvation and cannibalism explains two themes: it describes how reality shapes human behavior and compares the character of Kurz and Marlow. The "reality" used here is defined as "civilized one". Conrad emphasizes the truth, darkness, civilization, primitive, colonization, colonization. I will pierce the heart of the dark. As mentioned above, "real" in this case includes every meaning of civil society. Clothes covering human organs, suppressing overeating, always relying on clocks as conductors of action.
The two themes of "the heart of darkness" are the contradiction between reality and "darkness", the concept of suppression and whether it is necessary, and paragraphs explaining eating are both examples. Human beings are practicing mysterious bondage that prevents them from meeting the basic needs of mankind; at the 2 nd level, they are in reality (what is civilization) and what is natural I will face. There is no concrete evidence that these people are like cannibalism, but the natural solution to their hunger is to eat, but that is not the case. Marlow, a person symbolizing the reality of civilization exercised this detention. This is a religious fake seen in the people of civilization he has seen so far. On the other hand, Kurtz abandons his detention and has already entered the "darkness" to say so. "A horrible event! Horror!" He said before he died.
