The variety within Mann's fiction is impressive and fascinating. But Joyce is even more various and many-sided. He begins his career with a wonderful sequence of bleak studies about the ways in which human lives can go awry - in my view, Dubliners is underrated.

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.

Those citizens are distracted by the toys technology has supplied, and fail to recognize the ways in which what they most deeply want is made vulnerable by the coming disruptions of human relations on an over-heated planet.

When I try to outline the history of ethical life, it's sometimes possible to find evidence for a hypothesis about how important transitions actually went. Often, however, that isn't so. There are many facts about human life in the Paleolithic we're never likely to know.

It's a very bad idea for scientific conclusions to be accepted because they fit with the political values of a group of researchers.

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!)

It's not at all a bad idea for scientific questions to be chosen because a democratic deliberation would identify them as important for people's lives.
