Frank Jackson on Implication - Dictionary of Arguments
Read III 92 Implication/Jackson/Def Robustness: (Jackson) a statement is robust if its assertiveness remains unaffected by the acquisition of information. III 93 The punch line for Jackson: the modus ponens comes into play for conditional sentences. Condition sets are not robust with respect to the falsity of their consequents. >modus ponens, >Conditional, >Implication paradox. III 94 Jackson: Assertiveness is measured by conditional probability. There is a specific convention about conditional propositions: namely, that they are robust with respect to their antecedents, and therefore cannot be claimed in circumstances where it is known that their antecedents are false. ReadVsJackson/ReadVsGrice: both are untenable. The problematic conditional sentences occur in embedded contexts. Example: Either if I was right, you were right, or if you were right, I was right. Assertion and assertiveness: are terms that are applied to complete statements, not to their parts! Conditional sentences are not truth functional. >Truth functions._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
