I'm a pluralist about perspectives on literature. There seem to me to be all sorts of illuminating ways of responding to major literary works, some of them paying considerable attention to context, others applying various theoretical ideas, yet others focusing on details of language, or linking the work to the author's life, or connecting it with other works.

After two years of undergraduate study, it was clear that I was bored by the regime of problem-solving required by the Cambridge mathematical tripos. A very sensitive mathematics don recommended that I talk to the historian of astronomy, Michael Hoskin, and the conversation led me to enroll in the History and Philosophy of Science for my final undergraduate year.

Part of my methodological approach is made explicit when I discuss ways in which literature can have philosophical significance. Literature doesn't typically argue - and when it does, it's deadly dull. But literature can supply the frame within which we come to observe and reason, or it can change our frame in highly significant ways. That's one of the achievements I'd claim for Mann, and for Death in Venice.

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.

I read Aschenbach's constant desire to go beyond the works he has already produced to be the counterpart of Mann's deep wish to surpass his previous fiction; sometimes the diaries express this in terms of a dejected judgment that the summit has already been reached.

The more you read the novella, the more you should wonder, I think, which judgments are to be taken as bedrock.

Presenting Aschenbach as a composer - based on Mahler - leads to some dreadful scenes (especially those in which Aschenbach is berated by his student), and it surely distorts the character Mann created. Yet, we know that Mann's novella was based on a holiday in Venice he took with his wife and brother, and that while he was there he followed the reports in the German newspapers, describing the dying Mahler's progress as he returned from New York to Vienna.
