Assertibility | Lewis | V 139
Assertibility/conditional/semantics/: we assume assertibility instead of truth because of the probability. However, assertibility is best gained through truth conditions plus a sincerity condition. Adams: the other way around: there are truth conditions not for the entire conditional, but individually for antecedent and consequent "plus a rule that assertibility of the indicative conditional is possible with the conditional subjective probability of the consequent given by the antecedent. Lewis pro (>Adams Conditional). LewisVsAdams: means something different: he calls this "indicative conditional" what Lewis calls a "probability conditional". Adams: the probability of conditionals is not equal to the probability of truth. AdamsVsLewis: probability of conditionals does not obey the standard laws of probability. Solution/Lewis: if we do not mention truth, probability of conditionals obeys the standard laws. Then the indicative conditional has no truth value and no truth conditions, i.e. Boolean connections, but no truth-functional ones (not Truth Functional). V 142
Assertibility/conditional/Lewis: assertibility should correspond to the subjective probability (Lewis pro Grice). The assertibility is reduced by falsehood or trivial being-true. This leads to conditional probability. From this we have to deduct the measured assertibility from the probability of the truth of the truth-functional conditional (horseshoe, ⊃). |

Belief Degrees | Adams | Field II 296
Adams-Conditional/Field: Suppose we add ">" to the general Adams conditional, which can only occur as a main operator, and which obeys the principle that the degree of belief in A > B is always the contingent degree of belief in B given A.
Belief Degree/Field: If we assume that contingent and not contingent belief is represented by conditional or unconditional Q, we obtain that the degree of belief in A > B is equal to Q (B I A).Adams-Conditional/Field: the normal Adams conditional assuming that belief degrees obey the probability laws captures the "if ... then" better than the probability function of the conditional. >Conditional, >Probability functions, >Probability, >Probability law, >Conditional Probability, >cf. >Bayesianism, >Subjective Probability. In any case, this only occurs as a main connection: E.g. "when I try it, I will be added to the team ("If I try out for the yankees, I will make the team"). Then the general Adams-conditional seems appropriate for vagueness. >Vagueness. If that is so, then the belief degree of A > B should be: Q (DA I A).
Probability function/belief degree: Difference: for the probability function, the contingent probability is never higher than the probability of the material conditional.
>Probability function.Williamson/Field: for his argument (1 - 3), this is important: all premisses get the Q value 1 if "if ... then" are read as a general Adams conditional. Then the classic conclusion is not valid in this reading of "if ... then". >T. Williamson. |

Conditional | Adams | Field II 252/296
Material Conditional/Adams Conditional/Field: (Lit. Adams 1974): (outside of mathematics): few of us would agree with the following conclusion: E.g. from
Clinton will not die in office to If Clinton dies in office, Danny de Vito will become President. That suggests that here the equivalence between A > B and ~(A v B) does not exist. >Counterfactuals, >Counterfactual conditional. In other words: If A then B does not seem to have the same truth conditions as ~A v B. >Truth conditions. Adams-conditional: it may only be used as a main operator. - The degree of belief of A > B is always the conditional belef degree (B I A). >Operators, >Conditional probability. II 253
In the case of the indicative conditional, the premise is always required. - Adams: intuitively, conclusions with conditionals are correct. Problem: then they will say less about the world.
Indicative conditional sentence/material implication/truth/field: further considerations have however led many to doubt that there are truth conditions here at all.>Material implication. Conditional/Field: A > B: here the premise A is always required when concluding. That is, we accept conditional B relative to premise A. Adams: the idea of contingent acceptance justifies our intuitive beliefs according to which conclusions with conditionals are correct. Cf. >Presuppositions, >Principle of Charity. But then it is anything but obvious that conditionals say something about the world. For example, there must not be a statement C whose probability in all circumstances is the same as the conditional (contingent) probability of (B I A). That is, the conditional A > B is not such a C. N.B.: this shows that we do not have to assume "conditional propositions" or "conditional facts". This is the nonfactualist view. >Nonfactualism. ((s) Truth conditions/nonfactualism/conditional/(s): if there are no facts, then there are also no truth conditions.) Borderline case: If the conditional (contingent) probability is 0 or 1, it is justifiable that the assertibility conditions (acceptance conditions) are the same as those of the material conditional. Vs: one could argue that a sentence without any truth conditions is meaningless. >Assertibility, >Assertibility conditions. Field: ditto, but the main thing is that one cannot explain the acceptance conditions without the truth conditions in terms of the truth conditions. >Truth conditions. 1. R. Adams (1974). Theories of Actuality. Nous, 5: 21-231. --- Lewis V 133
Conditional/Adams/Adams-conditional/Lewis: is an exception to the rule that the speaker usually expresses nothing that is probably untrue. - Then the assertibility goes rather with the conditional subjective probability of the consequent.

Sorites | Adams | Field II 297
Adams-Conditional/Sorites/Field: in Sorites, the generalized Adams conditional leads to all assumptions being highly credible, even for the clearest borderline cases. But the Sorites argument does not preserve the credibility in this reading.
>Conditional/Adams.Probability function P/Field: from several different P, the same Q can be constructed, so P is not really important to describe the agent. >Probability function, >Conditional probability. Then one could say: 1. That Q is a fully legitimated belief function. 2. That P is not a legitimate belief function. This would be hard to justify if the process from P to Q could be repeated so that it provides a Q* that is different from Q, but that is not the case. If we define Q*(A) as Q(DA), then Q* is simply equal to Q. This is our reason for using S4. >Systems S4/S5. |
