Abstract The 1985 paper by Carlos Alchourrón (1931–1996), Peter Gärdenfors, and David
Makinson (AGM),“On the Logic of Theory Change: Partial Meet Contraction and Revision …

Belief change (belief revision) is a research area in formal philosophy that makes use of
logic to produce models of how human and artificial agents change their beliefs in response …

Conditionals somehow express conditional beliefs. However, conditional belief is a bi‐
propositional attitude that is generally not truth‐evaluable, in contrast to unconditional belief …

One can ask many questions about belief and the relation between belief and degrees of
belief. Many of them can be asked and answered informally as well as formally. None of …

Epistemology is concerned with the fundamental laws of thought, belief, or judgment. It may
inquire the fundamental relations among the objects or contents of thought and belief, ie …

Degrees of belief are familiar to all of us. Our confidence in the truth of some propositions is
higher than our confidence in the truth of other propositions. We are pretty confident that our …

The AGM model for the revision and contraction of belief sets provides rationality postulates
for each of the two families of change operators. In the context of finite propositional logic …

The topic of conditionals is an extremely important one. It lies at the bottom of so many
philosophical issues (causation, dispositions, lawlikeness, etc.), and current theories of …

According to a suggestion by Williamson (Knowledge and its limits, Oxford University Press,
2000, p. 99), outright belief comes in degrees: one has a high/low degree of belief iff one is …

In this paper we study iterated contraction in the epistemic state framework, offering a
counterpart of the work of Darwiche and Pearl for iterated revision. We provide pure …
