I thought I should give the above conference a plug. As the organisers say:

This conference on Political Philosophy and Taxation will address the issue of how the activities of the state should best be funded. The conference will bring together a number of leading political philosophers, as well as a number of other scholars working at the intersection of political philosophy with economics, law and social policy. It will further the state of current research on taxation within political philosophy, as well as facilitating productive interdisciplinary dialogue on the topic.

Candidly, that's a pretty radical agenda. people just don't discuss this sort of thing in the UK right now, at least not in that way.

And the list of speakers is impressive, even if they have included me. See the full list here.

I know there are some places left, and it's free. I think it will be a fascinating two days.
