One of the five men on the ship in the Thames. Heart of Darkness is mostly made up of his story about his journey into the Belgian Congo. Marlow is a seaman through and through, and has seen the world many times over. Perhaps because of his journeys, perhaps because of the temperament he was born with, he is philosophical, passionate, and insightful. But Marlow is also extremely skeptical of both mankind and civilization, and, to him, nothing is simple. As the Narrator describes him: "to him the meaning of an episode was not inside like a kernel but outside, enveloping the tale which brought it out only as a glow brings out a haze." The one thing Marlow does seem to believe in as a source of simple moral worth is hard work.
