Look at Mann's reading habits, his explicit comments on Nietzsche, and his copy of Birth of Tragedy, and it starts to seem doubtful that this work of Nietzsche's played much role in the gestation of the novella.
Philip KitcherAs I read Mann in German for the first time, the full achievement - both literary and philosophical - of Death in Venice struck me forcefully, so that, when I was invited to give the Schoff Lectures at Columbia, the opportunity to reflect on the contrasts between novella and opera seemed irresistible.
Philip KitcherSo is fighting incompleteness the source of artistic neurosis? I doubt it. At most, this would apply to artists who deal with particular kinds of problems. I don't think we should think of Haydn or Mozart or Dickens or George Eliot in these terms.
Philip KitcherI'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.
Philip KitcherConsider the different narrative styles within the story, and the glee with which the "moralistic narrator" celebrates Aschenbach's fall - maybe, then, this is a hostile verdict and the international fame is warranted after all (given that Mann modeled his protagonist so closely on himself, it would be quite odd if he had intended Aschenbach's literary inferiority to be a fixed part of the interpretation).
Philip Kitcherconclude, what Thomas Mann really wanted was a limited physical relationship with beautiful young men: the opportunity to gaze at them, an occasional touch, a restrained kiss. That isn't a surrogate for what he'd like to have if he were somehow free from social constraints. It's what the young Platen wanted, it's what he wanted - and it's what his Aschenbach wants.
