Our traditional systems of decision-making are just not up to preventing changes in fundamental earth systems that are driven by a constant barrage of individually negligible emissions of an invisible, odorless gas, by billions of people all over the world.

Since we're not very good at something as basic as controlling our reproduction, life is really bad for more people than ever before.

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.

Philosophers (and probably most intellectuals) are more interested in pursuing what they see as the logical implications of their theories than they are in paying attention to the shlumpy diversity of defensible values that people actually have, and then trying to figure out how these might be negotiated in the life of an agent or community.

If you look at the works psychologists have done about individual reports of wellbeing, what happens is that if you're poor, you are not happy. But once you achieve a certain level of material satisfaction then income has very little correlation with people's reported states of happiness, things like climate matter more, things like the culture of the country in which you're raised matter more and so the things really, let's face it, like individual temperament matter more than these things.

If I drive my car to the store, those carbon molecules that are emitted actually get into the atmosphere circulation systems and affect climate in a global basis. This is shocking, this is amazing! No one in the 18th Century would have believed that anything like this were at all possible and I don't think we have, as part of our common sense, morality, norms and values that are really responsive to those kinds of issues, to the kind of power that we now are able to exert over the future and over people who live very far from us.

We can use economic instruments to help realize our goals but economics does not tell us what our goals should be.
