The hardest problem of all is to appreciate the facts that the poor nations are - quite reasonably - not going to forgo their development, and that they can only afford to develop by consuming fossil fuels.

Aschenbach is not only a projection of Mann in the obvious ways - same daily routines, author of the works Mann had planned - nor even in sharing his author's aspirations, doubts, and sexual identity. His watchword, "Durchhalten!" [persevere, keep going] could be Mann's own.

To my mind, Death in Venice represents an enormous advance in Mann's literary development, not simply for the commonly appreciated reason that he crafted a superbly supple and elegant style, apparently well suited to the kind of prose Aschenbach is supposed to write.

It may be hyperbolic to declare that Shakespeare teaches us more about being human than all the natural scientists combined.

Wilhelmine Germany was hostile to the expression of same-sex love - and, of course, Mann would have known of the fate of Oscar Wilde. His early reading of Platen's poetry, and, probably when he was in his early twenties, of Platen's diaries, introduced him to a form of sexual expression he found profoundly congenial. It's not quite Platonic.

The result can be quite new - perhaps a tendency to judge that something we've never conceived of is possible, or to feel sympathy for a trait or a type of person whom we've regarded with indifference or even hostility.

I'm quite pessimistic about climate change. This is an urgent problem, and much of the world is only now waking up to the easiest part of solving - the realization that anthropogenic global warming is real.
