There are many themes everywhere in the novel "The Heart of Darkness" in the two themes of Heart of Darkness. But there are mainly two important things. These are the themes that restraint and human nature enter self. The center of the dark emphasizes the importance of restraint. In the novel, Marlow was saved by detention, Kurtz was destined to fail due to his lack. As Congo colonization "has the idea behind it," Marrow got different feelings about Africa before going there. Despite the anxiety, he believes that detention will work there.
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 all meanings of civil society.
The theme of civilization and barbarism is the heart of the dark heart. It is also closely related both to light and dark, or white and black themes. Light and darkness traditionally represent good and evil, civilization is usually regarded as good, and savage is usually regarded as evil. However, this symbolic meaning is not new, and these implications have existed in society for centuries. As in the dark ages, it refers to the Middle Ages where science and knowledge are suppressed. According to Christianity, everything was dark at the beginning, God made light. Conrad uses this theme extensively, sometimes using traditional image methods, sometimes creating meaningful flips that are surprising and unexpected. Through the image of light and darkness, the fear of colonization is highlighted, and the theme of civilization and barbarism is emphasized.
