I haven't anything interesting to say for myself on this topic; but via my friend Chris Brooke, I see that Why Inequality Matters, a pamphlet co-authored by our friend-in-common Ben Jackson is now available for free online. Ben's a super guy, who's great company even if discussing Leonard Hobhouse and Isaiah Berlin's liberalisms, or Hugh Gaitskell and Evan Durbin's economic thought isn't your idea of a good time (though, if this is the case ... well, you poor, benighted creature, you); he also combines top-knotch skills as a political theorist and historian of British political thought. So I tend to think that anything he writes is likely to be good.
All of that said, I have yet to actually read this pamphlet, so can't say anything about it, substantive or otherwise. But I thought I'd call it to people's attention, and open up a space for any of my co-bloggers, who have a stronger footing in the theoretical literatuer on, and debates about, equality, to weigh in -- if they have the time and inclination to read the piece.
