In elaborating how "philosophy by showing" works, and in defending the idea that literature and music can contribute to philosophical "showing", I am also doing something more standardly philosophical. But I view most of the book as an interweaving of philosophy and literary criticism. If that entails a broadening of a standard idea of philosophy, it's a broadening I'd like to see happen.

One of the things I want to do in the book is to explore how philosophy can be done in literature. I start doing that in the first chapter, by introducing the idea of "philosophy by showing". What literature/philosophy shows is how to look at some important facets of life in a new way, thus changing the frame in which subsequent philosophical argument proceeds.

We know that he gave Aschenbach Mahler's first name, and also his facial features. So Visconti picks up on something interesting. That led me to think about ways of developing further the Aschenbach-Mahler connection.

I suspect that any worthwhile exploration of these deep questions about living requires going beyond abstract discussions to the vivid presentation of possibilities. If readers are to be prompted to serious examination of their lives, anatomy isn't enough. We have to be stimulated to imagine, in some detail, what it would be like to live in particular ways.

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.

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.

Both Proust and Joyce record the ways in which human perspectives can be transformed. In Portrait, Stephen Dedalus is constantly undergoing epiphanies, but their effects are transitory: the new synthetic complex quickly falls apart. Proust's characters, by contrast, often achieve lasting changes of perspective.
