I take seriously the idea that we are African Apes who (at least for the moment) dominate the planet, but our psychology is pretty much what it was when we were living in small groups on the savanna.

The millennium development goals are important, both morally and economically, because much of the world's population maybe is as much as a third of the world's population hasn't yet reached the level of economic development where we begin to get a dissociation from people's economic status and their reports about personal happiness. So we really do need to do much more and much more effectively in order to give everyone the kind of basis for which they can have good vibes.

In the face of the collective action problems that are at the heart of the environmental crisis, consequentialists should seek to inculcate the "green virtues" which includes the virtue of cooperativeness. This would not bring about the best possible world but it would set us on the path of making it better.

Obama's clean power plan, methane regulations, and increased fuel economy standards are about as good as our political system can do at this point in our history. Let's embrace these things, make them work, and push for more, rather than denouncing them because they're 9th best (which they are).

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.

None of us are rational economic men as we're supposed to be portrayed in economic theory where mixes of passions, of desires, of moral principles, of self-deception, of altruism, of concern of others, of concerns for ourselves and an interest in our bank accounts. And social policies have to be responsive to the complexity of who we are as people or else, like the war on drugs, they're simply going to fail.

Since for me moral demands necessarily flow from human psychology, I don't think we can be obliged to do something that we are not motivated in any way to do. In other words, I'm an "internalist" about morality.
