The variety within Mann's fiction is impressive and fascinating. But Joyce is even more various and many-sided. He begins his career with a wonderful sequence of bleak studies about the ways in which human lives can go awry - in my view, Dubliners is underrated.

So this is my attempt to give a preliminary - probably far too crude - account of how philosophy by showing can really teach us. The attempts we make to work through problems by reasoning always presuppose starting points, and even the most self-critical philosophers adopt some of those starting points simply by picking them up from the social environments in which they grow up.

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.

I use biography, I use literary connections (as with Platen - this seems to me extremely helpful for appreciating the nuances of Mann's and Aschenbach's sexuality), I use philosophical sources (but not in the way many Mann critics do, where the philosophical theses and concepts seem to be counters to be pushed around rather than ideas to be probed), and I use juxtapositions with other literary works (including Mann's other fiction) and with works of music.

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.

Philosophy by showing - including philosophy in literature - does truly valuable work in leading us to new perspectives from which our arguments can then begin. It does so by introducing new synthetic complexes, which we then reflect on from various points of view. When the complexes survive and grow, that initial showing has been philosophically decisive.

There are many critics whose work I greatly admire. Even though I diverge from T.J. Reed in several important ways, I've learned greatly from his writings on Mann.
