A common rhetorical strategy of politicians and others is to frame their opponents' views in the worst possible light, tacitly suggesting that all versions of the view must be committed to some particularly deplorable conclusion. Philosophers are not immune to this way of arguing.

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

Is it in the UK's interests to leave the EU? It depends on your values. The answer can't be read off of GDP statistics under various scenarios or some measures of global influence.

Is it in the interests of Britain to leave or remain in the EU? As we saw in the referendum, there are different Britains and they see their interests in different ways. For a lot of everyday blokes the EU affected their sense of identity in ways they disliked, and they were right in thinking that the EU didn't return much to them by way of economic benefits.

I think when it comes to climate change, the single most important thing in the world is for the United States' Congress to pass an effective bill that will put a price in carbon because if it starts costing something to emit carbon, this will provide an incentive, people do act on the basis to some extent of economic incentives to emit fewer greenhouse gases.

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.

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.
