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.

When we read a literary work (or, in some instances, listen to music) our imagination is stimulated, we feel various emotions, and we arrive at new judgments. These attitudes are brought into relation with many others, including our standing tendencies to think and feel in particular ways, and we try to fit our psychological capacities and responses together.

For a pragmatist like me, the important issues concern the words we might deploy to achieve our purposes, rather than the language we actually use.

It is hard to hide our genes completely. However devoted someone may be to the privacy of his genotype, others with enough curiosity and knowledge can draw conclusions from the phenotype he presents and from the traits of his relatives.

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.

Science literacy consists in the ability and the desire to follow reports of new scientific advances, throughout your whole life.

Mann was conscious of adopting different perspectives in different parts of the novella, but my guess is that there are plenty of passages in which the resonance of the words he chose struck him as exactly right (even though he didn't probe to discover exactly what tone or narrative device gave them that effect).
