Today

The discussion that started around Peter Grünwald's article continues in fairly broad circles. Today, Murray Shanahan responds to a question earlier in the discussion re the use of causal approaches to ramification in the event calculus. Pat Hayes, in a response to an earlier question by Vladimir Lifschitz, argues for the need to characterize instantaneous changes. (Compare also answer by Jixin Ma to a question re the paper by Knight, Peng and Ma at the Commonsense workshop, [c-fcs-98-183]).
