Principle of the contingently (conditionally) excluded middle/Stalnaker/BSAD/Lewis: Thesis: either wX>wY or wX> w~Y applies in every world - it follows that if Y, Y", ... are a partition and X is possible, then - wX>wY, wX>wY", ..., would also be a partition. - Then the conjunctions of full patterns are a partition. - Vs: 1) applies to arbitrary selections.
2) cannot deal with random events. - LewisVsVs: despite coincidences there is nothing vague or arbitrary in the counterfactual conditionals - They are simply wrong in coincidences._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
