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.

If there are to be appropriate judgments about what questions are significant, you need both the informed views of scientists who know what has been achieved and what future developments are promising and the reflective judgments of representatives of different groups who can identify what kinds of information are most urgently needed.

Both Ulysses and Finnegans Wake are inexhaustible. They are celebrations of the ordinary, compelling reactions to philosophical elitism about "the good life". I hope to examine both of them further, doing more justice to Joycean comedy than I did in my "invitation" to the Wake, and trying to understand how the extraordinary stylistic innovations, particularly the proliferation of narrative forms, enable Joyce to "see life foully" from a vast number of sides.

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.

In my current work on global warming, I argue that the only apparent solution to the deep problem of climate change would require very large transfers of wealth from rich nations to poor nations, so that the entire world can make the transition to renewable forms of energy as fast as possible.

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.
