Reapproaching Ramsey: Conditionals and Iterated Belief Change in the Spirit of AGM
2011
Journal of Philosophical Logic
According to the Ramsey Test, conditionals reflect changes of beliefs: α > β is accepted in a belief state iff β is accepted in the minimal revision of it that is necessary to accommodate α. ...
Since Gärdenfors's seminal paper of 1986, a series of impossibility theorems ("triviality theorems") has seemed to show that the Ramsey test is not a viable analysis of conditionals if it is combined with ...
Once one adopts a resolutely semantic point of view, there is a very natural resolution of the riddle surrounding the applicability of the Ramsey test in the context of AGM style belief change. ...

Conditional Questions
2008
Journal of Semantics
Instead, denials of the antecedent deny the presuppositions of the conditional, and do not directly address the question at all. ...
We propose that conditional questions are interpreted in two steps. First, a temporary context is created in which the propositional content of the antecedent obtains. ...

Popper's Severity of Test as an intuitive probabilistic model of hypothesis testing
2009
Behavioral and Brain Sciences
from a probabilistic point of view. ...
The probabilistic approach makes a variety of novel predictions which have been experimentally confirmed. ...
Indeed, O'Brien's account of conditionals is, instead, a strictly deductive version of the Ramsey test (like, e.g., Gärdenfors 1986) -conditionals are only asserted if the consequent, q, follows with certainty ...

Conditionals, meaning and mood
2010
This work explores the hypothesis that natural language is a tool for changing a language user's state of mind and, more specifically, the hypothesis that a sentence's meaning is constituted by its characteristic ...
Adapted to natural language by Davidson, Lewis, Montague, et. al. this dominant approach has crystalized as truth-conditional semantics: to know the meaning of a sentence is to know the conditions under ...
Ramsey is the addition of p?, then the proposal is on track to accommodate the conditionalinterrogative link. ...

Given a family of mixed 0-1 polyhedra, we suppose that the convex hull of solutions is known. Now we add a cardinality constraint such that the sum of the 0-1 variables is exactly k. ...
The existence of long-run (co-integrating) relationships between these variables are tested and the data suggests the existence of two long-run relationships: the first resembles an output equation, the ...

1993
For this, we ha.ve to make it the semantical component of a (liscourse grammar that implements the resolution (cf. [Priist 91a,b], which gives an example of the sort of gra.1nma.r we have in mind. ...
Furthmore, logics only formalize the use of discourse referents, not their resolution. ...
