The Rest of My Summer Reading (for This Year and Probably the Next)

I just received both volumes (all 1060 pages, not including appendices) of Derek Parfit's new book, On What Matters (Oxford 2011). My recollection, from reading Parfit's last book, Reasons and Persons (Oxford 1984), is that, although Parfit writes clearly, the sheer depth and complexity of his analysis makes for hard reading. I anticipate that the payoff to be high (otherwise, I wouldn't start reading the first page of the first volume). I cannot predict, however, how long it will take me to get to that payoff.
