In this era of globalization we are witnessing struggles within individual states about what their identity and interests consist in.

The Paris climate conference in December, 2015 was a recognition that countries bring their climate policies to international meetings rather than create them during the negotiations (much less do they receive orders from the international community and then go home and implement them).

People and countries have done an enormous amount of damage in their attempts to bring about the best possible world. Communism is an obvious example. But so is British imperialism, which was not grubby self-interest all the way down, but at least in part a sincere attempt on the part of people who felt they were superior to other people to magnanimously improve the lot of their inferiors.

Philosophy isn't reading Emmanuel Kant. Philosophy is about thinking hard about what the right thing to do is in a situation and approaching that kind of question in an open-minded and open-hearted way, receptive to a broad range of considerations and interests of other people and other things.

Environmental problems provoke challenges about what kind of world we want, how important we think it is if something is brought about by human action or by brute nature, what we think of the value of human life compared to that of other living things.

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." They want us to look at the world and ourselves in a different way. Someday these prohibitions against flying and eating meat may be written into our moral psychology, but it will only be after there are viable, widely shared alternatives that are beginning to be widely adopted.

Kantians are saddled with absolutist views, Aristotelians are accused of vagueness, and there is almost no horror to which Consequentialists are innocent of, according to some critics. While all these families of views have been victimized in these ways, Consequentialists have gotten the worst of it. I think this may have something to do with the fact that Kant and Aristotle are acknowledged to be great philosophers, and we tend to read the greats sympathetically, while Consequentialism is a family of views not rooted in the work of a single great man to whom this kind of deference is owed.
