Conditional: A conditional in logic is a statement that asserts a relationship between two propositions, typically in an "if-then" format. It states that if the antecedent is true, then the consequent must also be true. In contrast to (purely formal) implication, the conditional refers to the content of the propositions. See also Implication._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

D. Lewis on Conditional - Dictionary of Arguments
V 145 Definition Stalnaker-conditional/Lewis: A>C (pointed) is true iff the least possible change that makes A true also makes C true - (least possible revision). Lewis: the probability of Stalnaker-conditionals are usually not equal to the conditional probability. V 146 Stalnaker-conditional/Truth conditions/Lewis: T(A>C)) WA(C) if A is possible. V 148 Conditional/Credibility/Belief/Stalnaker: in order to decide whether to believe a conditional: 1) add an antecedent to the set of beliefs - 2) minimal corrections for consistency - 3) decide whether the consequent is true - LewisVsStalnaker: that is just conditionalization and not representation. V 153 Indicative conditional/assertibility/probability/Jackson/Lewis: the discrepancy between the assertibility of P (C I A) and the probability of the truth of P (A>C) lies with one or the other Gricean >implicature. - The right of access to this implicature must depart from the premise that the conditional has the truth conditions of the (truth-functional) A ⊃ C (horseshoe). - (Lewis pro). - Implicature: E.g. "here you are right" (but mostly you are wrong). >Assertibility. V 154 Indicative conditional/Lewis: is a truth-functional conditional that conventionally implies robustness (insensitivity to new information) in terms of the antecedent - hence the probability of both conditionals must be high - therefore the assertibility of the indicative conditional comes with the corresponding conditional probability. - maxim: "assert the stronger one"._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
