For anyone who conceives literature in terms of plurality of perspectives, Finnegans Wake has to be the apogee. For, as we are told, every word in it has three score and ten "toptypsical" meanings - an exaggeration, of course, but an important reminder to readers who like their fiction definite.

The balance between literature and philosophy in Schopenhauer and Nietzsche is different from that struck in the novella, but, as Mann clearly pointed out in his writings about both thinkers, both modes are present.

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.

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.

Mann was less interested, I think, in constructing any kind of "portrait of an age" than he was in delineating an individual consciousness in which profound struggles about identity and direction arise - struggles that Mann himself had not only reflected on but felt keenly. Visconti takes up this central focus of the novella, but he couples it with a more social perspective.

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").

If the research agenda reflects "market forces", the problems of the poor are likely to be even more neglected than they already are.
