Maxwell J. Cresswell on Equivalence - Dictionary of Arguments
II 78f Intensional Equivalence/Cresswell: one could replace "steal spoons" by the intensional equivalent substitute "steal spoons and either eat the cheese or not eat the cheese" - problem: the attribution of propositional attitudes changes the truth value. II 82 Many ordinary intensional but equivalent singular terms can be replaced. II 175 Equivalence/Propositional attitude/Cresswell: no logical equivalence can be assumed to be certain. - Therefore also no non-standard logic helps. - Not even for E.g. "Fred laughed and Betty laughed" can be interchanged in the sequence - (in belief contexts) - solution/Cresswell: different levels of sensitivity to the structure of the that-sentence - (part or whole)._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
