“[Kurtz] presented himself as a voice. Not of course that I did not connect him with some sort of action. Hadn’t I been told in all the tones of jealousy and admiration that he had collected, bartered, swindled, or stolen more ivory than all the other agents together? That was not the point. The point was in his being a gifted creature, and that of all his gifts the one that stood out pre-eminently, that carried with it a sense of real presence, was his ability to talk, his words—the gift of expression, the bewildering, the illuminating, the most exalted and the most contemptible, the pulsating stream of light, or the deceitful flow from the heart of an impenetrable darkness.”
