Hartry Field on Logical Possibility - Dictionary of Arguments
I 86 Logical possible/possibility/diamond/KripkeVsField: "it is possible that" is not a logical truth. - FieldVsKripke: yes it is, this is due to Kripke's model-theoretical definition. - It should not be read "mathematically" or "metaphysically possible". I 87 E.g. Carnap: "He is a bachelor and married": is logically wrong. - (> meaning postulates). - FieldVsCarnap: Meaning relations between predicates should not belong to logic. - Then the sentence is logically consistent. Consistency operator/Field: MEx (x is red & x is round) - should not only be true, but logical. - ((s) Even without meaning postulates.) ((s)Meaning postulate: this is about the extent of the logic.) I 118 Logical possible/FieldVsKripke: "It is possible that there is an electron": is true in all models, therefore logically true. (> Logical possibility is itself logically true)._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
