41Suszko’s problem: Mixed consequence and compositionalityReview of Symbolic Logic 12 (4): 736-767. 2019.Suszko’s problem is the problem of finding the minimal number of truth values needed to semantically characterize a syntactic consequence relation. Suszko proved that every Tarskian consequence relation can be characterized using only two truth values. Malinowski showed that this number can equal three if some of Tarski’s structural constraints are relaxed. By so doing, Malinowski introduced a case of so-called mixed consequence, allowing the notion of a designated value to vary between the prem…Read more

97Concept UtilityJournal of Philosophy 116 (10): 525-554. 2019.Practices of concept-revision among scientists seem to indicate that concepts can be improved. In 2006, the International Astronomical Union revised the concept "Planet" so that it excluded Pluto, and insisting that the result was an improvement. But what could it mean for one concept or conceptual scheme to be better than another? Here we draw on the theory of epistemic utility to address this question. We show how the plausibility and informativeness of beliefs, two features that contribute to…Read more

33From many-valued consequence to many-valued connectivesSynthese 198 (S22): 5315-5352. 2018.Given a consequence relation in many-valued logic, what connectives can be defined? For instance, does there always exist a conditional operator internalizing the consequence relation, and which form should it take? In this paper, we pose this question in a multi-premise multi-conclusion setting for the class of so-called intersective mixed consequence relations, which extends the class of Tarskian relations. Using computer-aided methods, we answer extensively for 3-valued and 4-valued logics, f…Read more

106Inexact Knowledge with IntrospectionJournal of Philosophical Logic 38 (2): 179-227. 2009.This paper supersedes an ealier version, entitled "A Non-Standard Semantics for Inexact Knowledge with Introspection", which appeared in the Proceedings of "Rationality and Knowledge". The definition of token semantics, in particular, has been modified, both for the single- and the multi-agent case.

53Subjectivity in gradable adjectives: The case of tall_ and _heavyMind and Language 33 (5): 460-479. 2018.We present an investigation of the ways in which speakers' subjective perspectives are likely to affect the meaning of gradable adjectives like tall or heavy. We present the results of a study showing that people tend to use themselves as a yardstick when ascribing these adjectives to human figures of varied measurements: subjects' height and weight requirements for applying tall and heavy are found to be positively correlated with their personal measurements. We draw more general lessons regard…Read more

183Question-embedding and factivityGrazer Philosophische Studien 77 (1): 85-125. 2008.Attitude verbs fall in different categories depending on the kind of sentential complements which they can embed. In English, a verb like know takes both declarative and interrogative complements. By contrast, believe takes only declarative complements and wonder takes only interrogative complements. The present paper examines the hypothesis, originally put forward by Hintikka (1975), that the only verbs that can take both that -complements and whether -complements are the factive verbs. I argue…Read more
