On account of the Isabel closing:  Until further notice, put our syllabus topics back a week.  Thus, Kripke is now rescheduled for Sept. 25, Evans for  Oct. 2, etc.  PAPERS, however, are not put back; #1 is still due on the 25th, one week from today.  (The topics list on the web site is now complete.)
     It's possible but unlikely that the Univ. will announce some general scheme for making up the missed classes.  Assuming not, we'll decide collectively how best to do that.
