An analysis of disposition concepts by the Ramsey test
This is an essay on the understanding of disposition concepts, which exploits the Ramsey test semantics of conditionals for a refined conditional analysis of dispositions. I will show that this…

Measuring Ranks via the Complete Laws of Iterated Contraction
- MathematicsFormal Models of Belief Change in Rational Agents
The paper shows how to reconstruct a ranking function from its iterated contraction behavior uniquely up to multiplicative constant and thus how to measure ranks on a ratio scale by giving a complete axiomatization of that behavior.
Ordinal and Probabilistic Representations of Acceptance
- PhilosophyJ. Artif. Intell. Res.
It is shown that the sets of accepted belief of an agent can always be derived from a family of possibility rankings of states, and considers the acceptance relation as a primitive object from which belief sets are derived in various contexts.
A Ramsey Test Analysis of Causation for Causal Models
- PhilosophyThe British Journal for the Philosophy of Science
We aim to devise a Ramsey test analysis of actual causation. Our method is to define a strengthened Ramsey test for causal models. Unlike the accounts of Halpern and Pearl () and Halpern…
Causation in terms of production
- PhilosophyPhilosophical Studies
In this paper, we analyse actual causation in terms of production . The latter concept is made precise by a strengthened Ramsey Test semantics of conditionals: $$A \gg C$$ A ≫ C iff, after suspending…
On Belief Promotion
A new class of belief change operators, named promotion operators, are introduced, which are to enhance the acceptation of a formula representing a new piece of information and provide a representation theorem in terms of minimal change.
On the Ramsey Test Analysis of ‘Because’
The well-known formal semantics of conditionals due to Stalnaker (in: Rescher (ed) Studies in logical theory, Blackwell, Oxford, 1968), Lewis (Counterfactuals, Blackwell, Oxford, 1973a), and…
On Iterated Contraction: Syntactic Characterization, Representation Theorem and Limitations of the Levi Identity
This paper provides pure syntactical postulates for iterated contraction in the epistemic state framework, that is, the postulates are expressed only in terms of the contraction operator, and establishes a representation theorem for these operators.
The Strength of Desires: A Logical Approach
- PhilosophyMinds and Machines
A formal approach to reasoning about desires is proposed, understood as logical propositions which the authors would be pleased to make true, also acknowledging the fact that desire is a matter of degree.
