Players of epistemic games – computer games that simulate professional practica – have been shown to develop epistemic frames: a profession’s particular way of seeing and solving problems. This study examined the interactions between players and mentors in one epistemic game, Urban Science. Using a new method called epistemic network analysis, we explored how players develop epistemic frames th...

Epistemic logic in the tradition of Hintikka provides, as one of its many applications, a toolkit for the precise analysis of certain epistemological problems. In recent years, dynamic epistemic logic has expanded this toolkit. Dynamic epistemic logic has been used in analyses of well-known epistemic “paradoxes”, such as the Paradox of the Surprise Examination and Fitch’s Paradox of Knowability...

this paper attempts to indicate that the two conceptual categories of evidentiality and epistemic modality are distinct although they may look similar; thus their corresponding adverbs also consist of separate subcategories of adverbs. to attain this goal, different data were gathered both from written and spoken sources and analyzed mostly with the help of semantic considerations in the framew...

The ways in which people seek and process information are fundamentally epistemic in nature. Existing epistemic cognition research has tended towards characterizing this fundamental relationship as cognitive or belief-based in nature. This paper builds on recent calls for a shift towards activity-oriented perspectives on epistemic cognition and proposes a new theory of ‘epistemic commitments’. ...

This article discusses the arguments against associating epistemic responsibility with the ordinary notion of agency. I examine the various “Kantian” views which lead to a distinctive conception of epistemic agency and epistemic responsibility, in particular the one proposed by Pamela Hieronymi (2007). I try to explain why we can be held responsible for our beliefs in the sense of obeying norms...

If I were to believe you are trustworthy just on your say-so, my reasoning would be infected with what is called epistemic circularity. I would be supposing a source is trustworthy by relying on that very source. Generally speaking, we tend to think this is a very bad idea. It is why we don’t bother asking politicians or salesmen whether they are honest. A well-known line of reasoning stemming ...

Epistemic trustworthiness is defi ned as a complex character state that supervenes on a relation between fi rstand second-order beliefs, including beliefs about others as epistemic agents. In contexts shaped by unjust power relations, its second-order components create a mutually supporting link between a defi ciency in epistemic character and unjust epistemic exclusion on the basis of group me...

Although epistemic logic programming has an enhanced capacity to handle complex incomplete information reasoning and represent agents’ epistemic behaviours, it embeds a significantly higher computational complexity than non-disjunctive and disjunctive answer set programming. In this paper, we investigate some important properties of epistemic logic programs. In particular, we show that Lee and ...

This paper takes a dynamical systems perspective on the semantic structures of dynamic epistemic logic (DEL) and asks the question which orbits DEL-based dynamical systems may produce. The class of dynamical systems based directly on action models produce very limited orbits. Three types of more complex model transformers are equivalent and may produce a large class of orbits, suitable for most...

This paper addresses and solves the long-standing open problem of whether Group Announcement Logic (GAL) is decidable. GAL is a dynamic epistemic logic for reasoning about which states of knowledge a group of agents can make come about by sharing their knowledge, with an operator for quantifying over all truthful public announcements that can be made by the group. We show that the satisfiabilit...
