In the last few centuries we've managed to reduce how much we kill each other, we've learned some basic lessons about public health, and life is relatively good for more people than ever before.

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.

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.

Philosophers tend to radically underestimate the distance between abstract principles (such as "reduce suffering") and what it might actually mean for people to act on them.

There'll come a time when airplanes are much more efficient when it comes to producing lower levels of greenhouse gas emissions, there'll come a time when we'll be able to offset those emissions much more effectively than we do now. But alas at the moment, flying airplanes is really one of the least defensible things that we do and it's one of the things that I indulge in quite frequently, alas.

It's obvious that there are vast variety of consequentialist views, depending on what we think goodness consists in, what our notion of consequence is, and what level (or levels) of human action we think the principle should be applied.

Progressive Consequentialsm requires us to make the world better but we are under no obligation to bring about the best possible world.
