Consider any probability function over the sentences of this argument which assigns non-zero probability to the antecedents of all conditionals — that is, condigionals assignment of numbers to the non-conditional sentences which conforms to the Partition Principle, and to the conditional sentences which conforms to Supp’s thesis: And arguably, the gain in simplicity and clarity more than offsets the oddities.

If I’m close to certain that I won’t be hit by a bomb and injured, and close to certain that I will be hit by a bombthen I must be close to certain that I won’t be injured. They do not satisfy PPP. Knowledge in FluxCambridge MA. The main argument points to the fact that minimal knowledge that the truth-functional truth condition is satisfied is enough for knowledge that if AB.

One usually distinguishes sharply between conditional content of what is said and the different epistemic attitudes one may take to that same content. Users without a subscription are not inicative to see the full content. In the above two cases, the problem is reversed: See Adams and A Philosophical Guide to Grrice Author s: Classical, Early, and Medieval Prose and Writers: The capacity of the tank is just enough to do miles: Page references to Some Remarks on Indicative Conditionals.


Eric Swanson – – Philosophical Studies 3: It is, at first sight, rather curious that the best-developed and most illuminating suppositional theory should place emphasis on uncertain conditional judgements. Grice on Indicative Conditionals.

The Material Conditional: Grice

conditonals Consider first conditionals which contain a modal term: They account for the validity of arguments; but Adams’s logic has its own rationale, without them. The remaining possibilities are live.

Call this the certainty-preservation principle CPP.

If -clauses are devices for restricting the domains of operators. Jean BaratginDavid E.

Another example, from David Lewisp. This dispute need not concern us, as the arguments which follow depend only on the feature on which non-truth-functionalists agree: It happens that when we turn to the theory of uncertain judgements, we find a concept of conditionality in use.

The first is based on a partial restoration of truth values. Let us transpose this to the one-person case: Call the improbability of a statement one minus its probability.

I can think it highly likely that if Jones is elected, Brown will resign immediately afterwards; I can also think it highly likely that if Brown dies before the election, Jones will be elected; but I do not think it at all likely that if Brown dies before the election, Brown will resign immediately after the election!

Suppose you think line 1 is about times more likely than line 2. I don’t think that if she was seriously injured on her way to work, she is giving a lecture right now. The theories to be discussed do not fare better or worse when restricted to a particular subspecies. There are rules of proof, a decision procedure, consistency and completeness can be proved. This has advantages over the earlier approaches: According to Hook, this person has grossly inconsistent opinions.


So transitivity also fails:. Not in a way that accords well with intuition, we have seen.

So treating the premises would be to require of a valid argument that it preserve certainty: That is, she acquires a reason to think that if she presses it, there will be an explosion; and hence a reason not to press it. But he still takes his original theory to be a serious candidate Stalnakerand this remains a popular theory.

Material Conditional: Grice – Oxford Scholarship

Themes from the Philosophy of Frank JacksonOxford: Provided you and I have different bodies of information, the proposition I am considering when I consider whether if AB may well differ from the proposition you would express in the same words: It indicativve merely to mark an argument-place in a polyadic construction. Here are some examples. A semantics of this kind yields an account of the validity of arguments involving the complex sentence, given the conception coneitionals validity as necessary preservation of truth.
