38The text typed during the lecture on this slide should read rule2 rather than rule.Correct....jp581
38Implicit binding of the exists quantifier is too large. This is important because otherwise the statement holds when thing(1,2) and thang(2) is true but rule2(1) is false - this happens because false implies anything and the overlarge capture of the exists allows you pick a z for which the LHS is false.There should be an open bracket before the exists and a close bracket before the implication arrowjp581
