I found a deep kinship between Mahler's recurrent attempts to confront all sides of life and to affirm himself in the face of his own finitude, and Aschenbach's dedication to persevere in the literary evocation of beauty. Exploring this kinship led me to reflect on many of Mahler's songs and symphonies - and particularly his great masterpiece, Das Lied von der Erde. The end result was a way of reading Mann that I hadn't originally anticipated at all.

Mann was conscious of adopting different perspectives in different parts of the novella, but my guess is that there are plenty of passages in which the resonance of the words he chose struck him as exactly right (even though he didn't probe to discover exactly what tone or narrative device gave them that effect).

When I try to outline the history of ethical life, it's sometimes possible to find evidence for a hypothesis about how important transitions actually went. Often, however, that isn't so. There are many facts about human life in the Paleolithic we're never likely to know.

Was Mann himself fully aware of all the facets of his irony? Probably not - any more than Shakespeare was fully aware of all the riches subsequent critics have found in his plays.

I'm a fan of Hugh Kenner, Richard Ellman, Lionel Trilling and Frank Kermode. All these people have taught me how to read - but perhaps, above all literary critics, I'm indebted to Wayne Booth (several people have suggested to me that I'm trying to reinvent "ethical criticism").

Read Mann's notes, which contain precise accounts of cholera and its symptoms, and observe how careful he is throughout his fiction in getting medical details straight - then you might begin to wonder whether cholera is the only candidate for the cause of Aschenbach's death. What results from this, I think, is a deeper appreciation of Mann's brilliance in keeping so many possibilities in play. The ambiguity is even more artful than people have realized.

Mann is widely recognized as a master of irony and ambiguity, yet it's remarkable how quickly people foreclose options he carefully leaves open. Lots of readers - including eminent critics - jump to conclusions: that Nietzsche's Birth of Tragedy is a central background text, that Aschenbach is an inferior writer, that he's never been attracted by pubescent male beauty before, that he dies of cholera.
