                *********  ENRAC IS BACK  *********

Last year this newsletter had a discussion about modal logic that was 
initiated by John McCarthy's note "Modality, si! Modal logic, no!" and
Heinrich Wansing's answer. Joe Halpern contributed to the discussion 
last July, and John McCarthy answered. Joe Halpern has now answered to 
John McCarthy; his answer can be found at
   http://www.ida.liu.se/ext/etai/rac/notes/2000/01/orig.ps

The earlier contributions to the discussion can be found from the
ETAI webpage, or directly from:
