Logical omniscience vs. logical ignorance on a dilemma of epistemic logic
1995We propose in the paper a new solution to the so-called Logical Omniscience Problem of epistemic logic. Almost all attempts in the literature to solve this problem consist in weakening the standard epistemic systems: weaker sytems are considered where the agents do not possess the full reasoning capacities of an ideal reasoner. We shall argue that this

Logical Omniscience and Inconsistent Belief
1993Logical omniscience is the problem that we inherit from possible worlds analysis of cognitive propositional attitudes, such as knowledge and belief. The knowledge or belief of a cognitive agent is interpreted as being inversely proportional to its uncertainty. Possible worlds accessible to the agent define this uncertainty, since every such world might

The ‘Logical Omniscience’ of Reactive Systems
1991The problem of ‘logical omniscience’ continues to engage attention in AI. In this paper it is argued that the problem arises from interpreting formal properties of epistemic logics into agent performance domains, where agent cognition is taken to incorporate formula-manipulation, which then mirrors inference in the logic.
