We’re hoping to have a proper book event on Thomas Piketty’s _Capital in the Twenty-First Century_ in due course. That’s hard for those of us who have read it, because the book is so stimulating, so bursting with surprising facts and ideas, that there’s a lot to talk about. Still, I think I’ll permit myself to share a few thoughts that I had about the way in which reading Piketty might impact on teaching political philosophy, and, specifically, teaching Rawls and the difference principle.

_A Theory of Justice_ came out in 1971 and was composed during the period the French call the _trente glorieuses_ . During that period it was easy to believe that the power of inherited wealth had melted away and that we were living in a new era of more equal opportunity, with careers open to talents and income inequalities largely explained by the differences in talent and ability that the parties in the original position were denied knowledge of. To be sure, 1960s America (like 1960s Europe) hadn’t accomplished that social-democratic meritocratic ideal, but it was kind of visible in embryo, waiting to be born. Rawls’s book took us way beyond that, challenging the glib assumptions about desert that the winners flattered themselves with, but in its toleration of some inequality for the greater good (and particularly for the benefit of the least advantaged), Rawls’s view was recognizably connected to a then-emerging social reality.
