Those citizens are distracted by the toys technology has supplied, and fail to recognize the ways in which what they most deeply want is made vulnerable by the coming disruptions of human relations on an over-heated planet.

First, my frame of reference for the Britten opera shifted. I'd always thought of Britten's approach in Death in Venice as another exploration of the plight of the individual whose aspirations are at odds with those of the surrounding community: his last opera returning to the themes of Peter Grimes. As I read and listened and thought, however, Billy Budd came to seem a more appropriate foil for Death in Venice.

The moment in which the narrator, reaching for his boots, becomes vividly and lastingly aware of the finality of his grandmother's death is another such moment. It would be interesting to explore Proust's great novel from the perspective of seeing how stable synthetic complexes are formed and modified.

In the end, we learn about the most basic philosophical questions - like "How to live?" - from a broad mixture of sources, including literature and philosophy, history and anthropology. These sources can guide our reflections on our own experiences, as we explore and reconsider. Mann contributed to such explorations in a distinctive way, and I hope my book brings that out.

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.

Ethical inquiry has always been motivated by the aim of improving human conduct. It doesn't follow from that that the goal is to produce a complete rule book that would be applicable to all cases.

I think the tone of mockery Heller finds is a part of Mann's irony, but only a part - a brilliant further touch consists in juxtaposing perspectives so that we're led to wonder whether the mockery itself is the last word.
