Noted: Edward Said
From Edward Said's Culture and Imperialism:
What makes Conrad different from the other colonial writers who were his contemporaries is that, for reasons having partly to do with the colonialism that turned him, a Polish expatriate, into an employee of the imperial system, he was so self-conscious about what he did. Like most of his other tales, therefore, Heart of Darkness cannot just be a straightforward recital of Marlow's adventures: it is also a dramatization of Marlow himself, the former wanderer in colonial regions, telling his story to a group of British listeners at a particular time and in a specific place. That this group of people is drawn largely from the business world is Conrad's way of emphasizing the fact that during the 1890s the business of empire, once an adventurous and often individualistic enterprise, had become the empire of business. [...] Although the almost oppressive force of Marlow's narrative leaves us with a quite accurate sense that there is no way out of the sovereign historical force of imperialism, and that it has the power of a system representing as well as speaking for everything within its dominion, Conrad shows us that what Marlow does is contingent, acted out for a set of like-minded British hearers, and limited to that situation.
Yet neither Conrad nor Marlow gives us a full view of what is outside the world-conquering attitudes embodied by Kurtz, Marlow, the circle of listeners on the deck of the Nellie, and Conrad. By that I mean that Heart of Darkness works so effectively because its politics and aesthetics are, so speak, imperialist, which in the closing years of the nineteenth century seemed to be at the same time an aesthetic, politics, and even epistemology inevitable and unavoidable. For if we cannot truly understand someone else's experience and if we must therefore depend upon the assertive authority of the sort of power that Kurtz wields as a white man in the jungle or that Marlow, another white man, wields as narrator, there is no use looking for other non-imperialist alternatives; the system has simply eliminated them and made them unthinkable. The circularity, the perfect closure of the whole thing is not only aesthetically but also mentally unassailable. (pp. 23-24; italics in original)
