Tristram continues to emphasize the tension between truth and fiction in his story. Teasing the reader, he elaborately “proves” his version of events despite knowing full well that the reader has no other choice but to believe his narration. The quasi-scientific method Tristram uses to date his conception is layered with irony, as his philosophical references emphasize. As Tristram argues with the reader about these details, he obliquely describes his parents’ character and social background, too.
