We address the issue of belief revision in a multi-agent setting. We represent agents' beliefs in a semantic manner, through a Kripke structure, and model a communication process by which agents communicate their beliefs to one another. We define a revision rule that can be applied even when agents have contradictory beliefs. We study its properties and show that agents need not agree after com...

In general, the best explanation for a given observation makes no promises on how good it is with respect to other alternative explana­ tions. A major deficiency of message-passing schemes for belief revision in Bayesian net­ works is their inability to generate alterna­ tives beyond the second best. In this pa­ per, we present a general approach based on linear constraint systems that naturall...

belief in the lofty positions and excellences of the shi’īte imams (a.s.) and having faith in their miraculous acts and dominion over the world affairs underlies the authentic doctrine of unconditional guardianship (wilāya al-takwīnī). when the imams’ devotees try to maintain a demigod status for the imams in line with this – possibly loving and devotional – belief beyond the conventional limit...

I argue that knowledge and rational belief are subject to stability conditions. A belief that amounts to knowledge couldn't easily have been lost due to the impact of misleading evidence. A belief that is rational couldn't easily have been withdrawn upon reflection on its epistemic credentials. In Chapter 1, I support a picture of epistemic rationality on which a belief, in order to be rational...

We describe a model of iterated belief revision that extends the AGM theory of revision to account for the effect of a revision on the conditional beliefs of an agent. In particular, this model ensures that an agent makes as few changes as possible to the conditional component of its belief set. Adopting the Ramsey test, minimal conditional revision provides acceptance conditions for arbitrary ...

Supernatural beliefs are ubiquitous around the world, and mounting evidence indicates that these partly rely on intuitive, cross-culturally recurrent cognitive processes. Specifically, past research has focused humans' intuitive tendency to perceive minds as part of foundations belief in a personified God—an agentic, morally concerned supernatural entity. However, much less is known about karma...
