When Nabokov talks about his butterflies, they become interesting even to those who despise them. This is because Nabokov, in addition to being a masterful writer, when he talks about butterflies, he talks about something that captivates him; he speaks enthusiastically, causing at least some of this great enthusiasm to radiate to the reader. With this example, it becomes easy to see that literature makes possible unlikely, unexpected, even impossible readings, provided the author is authentic and deals with subjects that truly interest him—acting as a host who, in an act of good faith, shows the visitor what he considers to be his most valuable possession. Perhaps the most evident effect of a great writer is precisely this: he stimulates, even if by force, the reader’s interest.
