Quote #19
"At this moment I heard Kurtz's deep voice behind the curtain: 'Save me!—save the ivory, you mean. Don't tell me. Save me!'" (3.18)
Kurtz is so debauched by greed that he assumes everyone feels the same way. He believes that the manager does not actually want to save him, but to save the ivory in order to look good to the Company. He is, of course, correct.
Quote #20
[Kurtz]: "'Sick! Sick! Not so sick as you would like to believe. Never mind. I'll carry my ideas out yet—I will return. I'll show you what can be done. You with your little peddling notions - you are interfering with me. I will return.'" (3.18)
Kurtz—apparently ignoring the fact that he is literally dying—still thinks he's going to win. He considers not only that the manager himself is less powerful than he, but that the manager's ideas are merely "little peddling notions" beside his own great ambitions.
Quote #21
"A clean-shaved man, with an official manner and wearing gold-rimmed spectacles, called on me one day and made inquiries, at first circuitous, afterwards suavely pressing, about what he was pleased to denominate certain 'documents.' I was not surprised, because I had had two rows with the manager on the subject out there. I had refused to give up the smallest scrap out of that package, and I took the same attitude with the spectacled man. He became darkly menacing at last, and with much heat argued that the Company had the right to every bit of information about its 'territories.' And said he, 'Mr. Kurtz's knowledge of unexplored regions must have been necessarily extensive and peculiar - owing to his great abilities and to the deplorable circumstances in which he had been placed: therefore - ' I assured him Mr. Kurtz's knowledge, however extensive, did not bear upon the problems of commerce or administration. He invoked then the name of science. 'It would be an incalculable loss if,' etc., etc. I offered him the report on the 'Suppression of Savage Customs,' with the postscriptum torn off. He took it up eagerly, but ended by sniffing at it with an air of contempt. 'This is not what we had a right to expect,' he remarked. 'Expect nothing else,' I said. 'There are only private letters.' He withdrew upon some threat of legal proceedings […]." (3.49)
The Company has all kinds of arguments about why they really need Kurtz's papers—devotion to science, legal right, etc.—but they obviously just want one thing: profit.
