Every country now has its own domestic political debate about how to respond to climate change. This is where the action is.

We need more science, but what we especially need is science fiction.

We think of history as another specialization, like philosophy of language, rather than as something that informs everything we do and think.

Is it in the interests of Britain to leave or remain in the EU? As we saw in the referendum, there are different Britains and they see their interests in different ways. For a lot of everyday blokes the EU affected their sense of identity in ways they disliked, and they were right in thinking that the EU didn't return much to them by way of economic benefits.

It's possible that we'll screw up the climate so badly that most of us will die and a few breeding pairs will remain somewhere in the arctic. What's more likely is that we'll continue remaking the planet, driving many species to extinction, killing millions of people through the indirect effects of climate change, making life even harder for the poor and powerless than it is now, and making it a little more difficult for the global middle class to live the lives to which they have become accustomed - in other words, business as usual, only worse.

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.

The problem is that for almost any feature of humanity that you can name, whether it's the ability to suffer, whether it's the capacity to reason, whether it's having lives that can go better or worse, there are at least some other non-human animals that have all of these features as well. So to exclude non-human animals from the range of moral concern but to include all humans, just seems morally arbitrary.
