This is a powerful book about the depths of evil a man can plunge into. Conrad describes the darkness of the jungles of Africa as well as the darkness of imperialism on Africa and its inhabitants. Last, he shows us the darkness of a man who had unlimited potential for good, but suffered the terrible consequences of greed and selfishness and pride. This is a much better description of a man obsessed than the highly overrated Moby Dick. I would recommend that the reader learn a little bit about King Leopold of Belgium and the fiefdom he created in the Congo. It will certainly help understand the underlying story.
