Science literacy consists in the ability and the desire to follow reports of new scientific advances, throughout your whole life.
I read Aschenbach's constant desire to go beyond the works he has already produced to be the counterpart of Mann's deep wish to surpass his previous fiction; sometimes the diaries express this in terms of a dejected judgment that the summit has already been reached.
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.
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.
