I played with English and Sociology in college but dropped out to work in the anti-war movement. I was going around denouncing the Viet Nam war as immoral but one day it dawned on me that I didn't know what that meant. I signed up for an ethics class at San Francisco State to find out the answer.

People who go around saying that it is wrong to fly and to eat meat are not so much making appeals to us from within our shared morality, but engaging in something more like "persuasive definition."

Even those who specialize in the history of philosophy often ignore the political and cultural context, and the natural world in which their philosophers were philosophizing. This has consequences both trivial and important. If you systematically read the last fifty years of the major journals in our discipline you would be amazed at the amount of redundancy. Most of this is unacknowledged because most of us know so little about the history of our discipline and even the subfields in which we work.

Climate change is not going to be prevented. It's not even going to be mitigated to the degree a rational person would want. As a result we're going to have to live with climate change and try to reduce the extent and rate of change as much as possible. This is not an inspiring or sexy project.
