Conditional | II 253 Conditional/Deflationism/Field: the nonfactualist view is not the only one possible, both classical and non-classical logic can be used. - Disquotational truth: it seems to require truth conditions. - E.g. "If Clinton dies in office, Danny de Vito will become President" is true iff Clinton dies in office and de Vito becomes President. II 254 Conditional/Facts/Stalnaker/Field: (Stalnaker 1984): Thesis: the conditional facts are not expressible in 1st order logic, but in indicative "If .. then .." clauses. II 255 Conditional/Factualism/Field: 1st Variant: assumes that "if A, then B" has the same truth conditions as "~A v B" - Factualism: factualism does not accept counterintuitive conclusions - Non-factualism: seems committed to them. II 255 Material Conditional/Paradoxes of Material Implication/Jackson/Field: Best Solution: (Jackson 1979): Thesis: counterintuitive conclusions are unacceptable here: Thesis: the conclusions are not assertible, but nevertheless they are true. - There is a conventional implicature for that when we assert "if A, then B", that not only the probability P (A> B) is high, but also the conditional probability P (A> B I A). - Point/Field: the requirement that P(A > B I A) should be high is equivalent to the demand of the nonfactualist that P(B I A) is high - "Surface logic" has to do with assertibility - "Deep logic": says what is truth preserving. II 256 Factualism: must then distinguish between levels of total unacceptability (i.e. on the surface) and the acceptability on a deep level - Deflationism: in the same way the deflationism can then distinguish between non-factualism and factualism without using the concepts "true" or "fact" - factualism: factualism does not accept counterintuitive conclusions - non-factualism: seems committed to them. II 257 Non-Factualism/Field: must assume that the acceptance of conditionals is not regulated by the normal probability laws governing the acceptance of "fact sentences". |
