Honesty in Partial

چکیده
We propose an epistemic logic in which knowledge is fully introspective and implies truth, although truth need not imply epistemic possibility. The logic is presented in sequential format and is interpreted in a natural class of partial models, called balloon models. We examine the notions of honesty and circumscription in this logic: What is the state of an agent thatònly knows '' and which honest ' enable such circumscription? Redeening stable sets enables us to provide suitable syntactic and semantic criteria for honesty. The rough syntactic deenition of honesty is the existence of a minimal stable expansion, so the problem resides in the ordering relation underlying minimality. We discuss three diierent proposals for this ordering, together with their semantic counterparts, and show their eeects on the induced notions of honesty. A short version of this paper has been published in the corresponding proceedings HJT94].

متن کاملMeanings of Foundational Virtue in Islamic Mystical Ethics: A Case Study of Honesty
In mystical ethics, some virtues have a foundational role in relation to other virtues; that is, other virtues are in some ways dependent on, conditional to, or rooted in them. This is a gradational concept, and therefore one can speak of foundational and more foundational among foundational virtues in mysticism. Honesty is the most foundational virtue in mystical ethics, and other virtues are ...
