Who said "Du calme, du calme, adieu"?
Before Marlow departs for Africa, his doctor says this statement to him. This statement is interesting because the doctor is saying it to him in warning about the potentials of madness, yet his warning is to "be calm." Thus, there is an irony presented that echoes the ideas of the novella, since the whole of the novella is a study of humanity and the line between sanity and madness. It is also interesting that the doctor who is speaking is not a native Englishman and even remarks that Marlow is the first Englishman that he has examined, since that shift from sanity to madness is traced by Marlow's journey from England and "civilized society" to the depths of Africa and the "heart of darkness."
