Yea, i'm doing Heart of Darkness. I found this somewhere:
Heart of Darkness by Joseph Conrad
Heart of Darkness shows the story of Marlow, as he travels to the Congo in search for the mysterious Mr Kurtz. Heart of Darkness can be interpreted as a journey that is of a lonely and unpleasant nature. The novel is significant because of its philosophical and literary qualities. With its climate of doubt and vagueness, it’s lost of moral confidence, its need for beliefs in the midst of moral wilderness, its exploration of the subconscious, and its affirmation of individual freedom this novella is highly significant in the exploration of physical journeys.
Each of us carries a darkness that is unique, our own ‘interior landscape’. The novel is vague however this is because Conrad attempts to evoke the feelings of that landscape into the responder’s mindset. This therefore consolidates understanding of physical journeys, as the responder is orientated to the environment in which the physical journey is taking place.
