Something to keep an eye out for.  Many interpreters of Rawls believe that the core argument for his two principles does not appear where he says that it does, in the middle sections of chapter 3, but in secs. 11-13 of chapter 2 (particularly in sec. 12).  Others believe that the core argument for his two principles appears in a late section of chapter 3, sec. 29.  We will be focusing on the sec. 29 argument for tutorial, but it is very helpful, both for that paper and for understanding Rawls, to focus on the secs. 11-13 (particularly sec. 12) argument as well.  See you tomorrow for class at 1:15 at The Press!
