After two years of undergraduate study, it was clear that I was bored by the regime of problem-solving required by the Cambridge mathematical tripos. A very sensitive mathematics don recommended that I talk to the historian of astronomy, Michael Hoskin, and the conversation led me to enroll in the History and Philosophy of Science for my final undergraduate year.

Sometime during the 1990s, when I was teaching philosophy at UCSD, my friend, colleague, and music teacher, Carol Plantamura, discussed the possibility of teaching a course together looking at ways in which various literary works (plays, stories, novels) had been treated as operas, and how different themes emerged in the opera and in its original. One of the pairings we planned to use was Mann's great novella and Britten's opera. Unfortunately, the course was never taught, but the idea remained with me.

I believe that the arts make indispensable contributions to our understanding.

Both Proust and Joyce record the ways in which human perspectives can be transformed. In Portrait, Stephen Dedalus is constantly undergoing epiphanies, but their effects are transitory: the new synthetic complex quickly falls apart. Proust's characters, by contrast, often achieve lasting changes of perspective.

I think the tone of mockery Heller finds is a part of Mann's irony, but only a part - a brilliant further touch consists in juxtaposing perspectives so that we're led to wonder whether the mockery itself is the last word.

My ethical naturalism sees us as facing the predicament of being social animals without evolved adaptations that make social life easy. The fundamental problem that sparks the ethical project lies in our limited responsiveness to one another. The only way we have to address that problem is through a representative, informed, and engaged conversation.

Philosophers ought to aspire to know lots of different things and to forge useful synthetic perspectives.
