I suggest in my own discussion of this episode, Mann invites us to set the attempt to philosophize about his predicament in the context of Aschenbach's life. The literary presentation thus adds to the naked philosophical skeleton.

I take the ethical truths to be the stable elements that emerge out of ethical progress and that are retained under further ethical progress.

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.

Think about Mann's own daily routine (ascribed to Aschenbach), read the extant diaries and the letters in which he discusses the novella's themes, and it won't be so obvious that the attraction to Tadzio is completely unprecedented; it also won't be obvious that what Aschenbach wants is full sexual contact.

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.

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.

Britten's opera tends to see things in simpler terms. It portrays an Aschenbach who wants a richer form of sexual fulfillment, and who is hemmed in by the social conventions to which he subscribes. But Visconti's use of the Mahler Adagietto is perfect for what I take to be Aschenbach's sexual desire.
