We're highly adaptable and have developed some powerful systems of representation.

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.

What most forms of Consequentialism cannot do is require us to act in such a way as to make the world worse, yet many of the objections to Consequentialism purport to show that Consequentialism requires us to make the world a stinking, bloody mess. The ubiquity of these kinds of arguments shows you just how unseriously many of the critics take Consequentialism.

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.

Bentham spent much of his life writing constitutions and proposing legal reform in the light of his utilitarianism. The evaluation of particular acts was hardly his concern. The psychology of his day was hedonistic and he worked in that framework and passed it on to Mill, but it is clear as day that Mill was not a hedonist in the sense in which we use that term today, though he used the language of pleasure and pain to express his views.

Aristotle thought that humans are rational animals and Hobbes thought that we act on the basis of rational self-interest. If only! It's not that we never do these things, it's that they are hardly constituative of who and what we are.

Climate change involves fundamental choices about how we want to live and what kind of world we want.
