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.

I'm very suspicious of the idea of a "final theory" in natural science, and the thought of a complete system of ethical rules seems even more dubious.

The classical allusions and the Platonic disquisitions on beauty are no longer a form of cover, but integral to Aschenbach's complex sexuality. Moreover, the wandering around Venice in pursuit of Tadzio isn't a prelude to some sexual contact for which Aschenbach is yearning.

Mann's sexuality and his attitudes towards it are extremely complex - and the complexities are inherited in the figure of Aschenbach. Mann had lived through a series of (almost certainly unconsummated) relationships with young men.

Mann was profoundly influenced by two philosophers, Schopenhauer and Nietzsche, who returned to the most ancient of all philosophical questions - "How to live?" - and whose writings offered novel perspectives for considering that question (much more perspective-offering than rigorous argument!)

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.

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.
