Do you think there is a symbolic purpose to the fogbank that Marlow passes through as he exits the last vestiges of European imperialist presence and enters the world of Kurtz? On the one side of the fogbank, you have the hypocrisy of European imperialism. On the other, you have the atrocities of unbridled individual ambition and human depravity. Do you think the fogbank is some kind of rubicon marking some point of no return? Or is a fogbank sometimes just a fogbank?
