251The Many Faces of Closure and Introspection: An Interactive PerspectiveJournal of Philosophical Logic 42 (1): 91-124. 2013.In this paper I present a more refined analysis of the principles of deductive closure and positive introspection. This analysis uses the expressive resources of logics for different types of group knowledge, and discriminates between aspects of closure and computation that are often conflated. The resulting model also yields a more fine-grained distinction between implicit and explicit knowledge, and places Hintikka’s original argument for positive introspection in a new perspective.

181M. Augier and J. G. March : Models of a man: Essays in memory of Herbert Simon (review)Minds and Machines 16 (2): 221-224. 2006.Herbert Simon was definitely 20th century’s most influential proponent of bounded rationality. His work was of a highly philosophical nature, but—as made clear time and again in this book—his ideas did not originate in philosophy at all. If the present collection of essays has any value to the philosophically oriented reader, it lies in the way it shows how a traditionally philosophical topic as human rationality and action cannot be claimed by philosophy alone. Even more, it shows that importan…Read more

112Relevant Information and Relevant Questions: Comment on Floridi’s “Understanding Epistemic Relevance” (review)Minds and Machines 24 (1): 71-83. 2014.Floridi’s chapter on relevant information bridges the analysis of “being informed” with the analysis of knowledge as “relevant information that is accounted for” by analysing subjective or epistemic relevance in terms of the questions that an agent might ask in certain circumstances. In this paper, I scrutinise this analysis, identify a number of problems with it, and finally propose an improvement. By way of epilogue, I offer some more general remarks on the relation between (bounded) rationali…Read more

66Local information and adaptive consequenceLogique Et Analyse 49 461-488. 2006.In this paper we provide a formal description of what it means to be in a local or partial information-state. Starting from the notion of locality in a relational structure, we define so-called adaptive gen- erated submodels. The latter are then shown to yield an adaptive logic wherein the derivability of Pφ is naturally interpreted as a core property of being in a state in which one holds the information that φ.
