I felt I should also contrast Visconti's treatment of the novella - usually damned by Mann fans (who typically respect Britten's more "faithful" adaptation). The Visconti film does many quite wonderful things, although there are good reasons for the condemnation.

Because the problems are objective features of the human situation - social animals without the capacities for making social life come easily - ethics is objectively constrained. It's not the case that "anything goes".

Schopenhauer's thought that Will is insatiable, that once satisfied in one form it must be expressed in new desires, is inherited both by Mann and by Aschenbach (it's in Mahler, as well). So life is inevitably incomplete.

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.

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.

Experiments work when, and only when, they call into action cognitive capacities that might reliably deliver the conclusions drawn.

If there are to be appropriate judgments about what questions are significant, you need both the informed views of scientists who know what has been achieved and what future developments are promising and the reflective judgments of representatives of different groups who can identify what kinds of information are most urgently needed.
