    Reaching Transparent Truth.Pablo Cobreros, Paul Égré, David Ripley & Robert van Rooij - 2013 - Mind 122 (488):841-866.
    This paper presents and defends a way to add a transparent truth predicate to classical logic, such that and A are everywhere intersubstitutable, where all T-biconditionals hold, and where truth can be made compositional. A key feature of our framework, called STTT (for Strict-Tolerant Transparent Truth), is that it supports a non-transitive relation of consequence. At the same time, it can be seen that the only failures of transitivity STTT allows for arise in paradoxical cases.

  2. Tolerant, Classical, Strict.Pablo Cobreros, Paul Egré, David Ripley & Robert van Rooij - 2010 - Journal of Philosophical Logic 41 (2):347-385.
    In this paper we investigate a semantics for first-order logic originally proposed by R. van Rooij to account for the idea that vague predicates are tolerant, that is, for the principle that if x is P, then y should be P whenever y is similar enough to x. The semantics, which makes use of indifference relations to model similarity, rests on the interaction of three notions of truth: the classical notion, and two dual notions simultaneously defined in terms of it, (...)

    Exhaustive Interpretation of Complex Sentences.Robert van Rooij & Katrin Schulz - 2004 - Journal of Logic, Language and Information 13 (4):491-519.
    In terms of Groenendijk and Stokhofs (1984) formalization of exhaustive interpretation, many conversational implicatures can be accounted for. In this paper we justify and generalize this approach. Our justification proceeds by relating their account via Halpern and Moses (1984) non-monotonic theory of only knowing to the Gricean maxims of Quality and the first sub-maxim of Quantity. The approach of Groenendijk and Stokhof (1984) is generalized such that it can also account for implicatures that are triggered in subclauses not entailed by (...)

    Optimal Assertions, and What They Implicate. A Uniform Game Theoretic Approach.Anton Benz & Robert van Rooij - 2007 - Topoi 26 (1):63-78.
    To determine what the speaker in a cooperative dialog meant with his assertion, on top of what he explicitly said, it is crucial that we assume that the assertion he gave was optimal. In determining optimal assertions we assume that dialogs are embedded in decision problems (van Rooij 2003) and use backwards induction for calculating them (Benz 2006). In this paper, we show that in terms of our framework we can account for several types of implicatures in a uniform way, (...)

    Pragmatic Interpretations of Vague Expressions: Strongest Meaning and Nonmonotonic Consequence.Pablo Cobreros, Paul Egré, Dave Ripley & Robert van Rooij - 2015 - Journal of Philosophical Logic 44 (4):375-393.
    Recent experiments have shown that naive speakers find borderline contradictions involving vague predicates acceptable. In Cobreros et al. we proposed a pragmatic explanation of the acceptability of borderline contradictions, building on a three-valued semantics. In a reply, Alxatib et al. show, however, that the pragmatic account predicts the wrong interpretations for some examples involving disjunction, and propose as a remedy a semantic analysis instead, based on fuzzy logic. In this paper we provide an explicit global pragmatic interpretation rule, based on (...)

    Explaining Quantity Implicatures.Robert van Rooij & Tikitu de Jager - 2012 - Journal of Logic, Language and Information 21 (4):461-477.
    We give derivations of two formal models of Gricean Quantity implicature and strong exhaustivity in bidirectional optimality theory and in a signalling games framework. We show that, under a unifying model based on signalling games, these interpretative strategies are game-theoretic equilibria when the speaker is known to be respectively minimally and maximally expert in the matter at hand. That is, in this framework the optimal strategy for communication depends on the degree of knowledge the speaker is known to have concerning (...)

    Games and Quantity Implicatures.Robert van Rooij - 2008 - Journal of Economic Methodology 15 (3):261-274.
    In this paper we seek to account for scalar implicatures and Horn's division of pragmatic labor in game?theoretical terms by making use mainly of refinements of the standard solution concept of signaling games. Scalar implicatures are accounted for in terms of Farrell's (1993) notion of a ?neologism?proof? equilibrium together with Grice's maxim of Quality. Horn's division of pragmatic labor is accounted for in terms of Cho and Kreps? (1987) notion of ?equilibrium domination? and their ?Intuitive Criterion?

    Identity, Leibniz's Law and Non-Transitive Reasoning.Pablo Cobreros, Paul Egré, David Ripley & Robert van Rooij - 2013 - Metaphysica 14 (2):253-264.
    Arguments based on Leibniz's Law seem to show that there is no room for either indefinite or contingent identity. The arguments seem to prove too much, but their conclusion is hard to resist if we want to keep Leibniz's Law. We present a novel approach to this issue, based on an appropriate modification of the notion of logical consequence.

    Game-Theoretic Pragmatics Under Conflicting and Common Interests.Kris De Jaegher & Robert van Rooij - 2013 - Erkenntnis:1-52.
    This paper combines a survey of existing literature in game-theoretic pragmatics with new models that fill some voids in that literature. We start with an overview of signaling games with a conflict of interest between sender and receiver, and show that the literature on such games can be classified into models with direct, costly, noisy and imprecise signals. We then argue that this same subdivision can be used to classify signaling games with common interests, where we fill some voids in (...)

    Vagueness and the Sorites.Robert van Rooij - unknown
    The principle of stability now says that if sentence ϕ is true/false in a model M, then ϕ has to stay true/false if M is getting more precise. Formally, let M = D, I be a refinement of M = D, I . Then it has to be the case that for all ϕ: (i) If VM(ϕ) = 1, then VM (ϕ) = 1. (ii) If VM(ϕ) = 0, then VM (ϕ) = 0.

    Pragmatic Value and Complex Sentences.Robert van Rooij - 2006 - Mind and Matter 4 (2):195-218.
    We investigate to what extent it is possible to determine a reasonable default pragmatic value of complex sentences in a compositional manner, and --when combined with a Boolean semantics --to see under which conditions it gives rise to reasonable predictions. We discuss several notions of pragmatic value, or relevance, and compare their behavior over complex sentences. Although the goal-oriented notions of relevance give rise to the same ordering relations between propositions,the conditions under which they behave 'compositionally' vary significantly.

    Towards a Uniform Analysis of Any.Robert van Rooij - 2008 - Natural Language Semantics 16 (4):297-315.
    In this paper, Universal any and Negative Polarity Item any are uniformly analyzed as ‘counterfactual’ donkey sentences (in disguise). Their difference in meaning is reduced here to the distinction between strong and weak readings of donkey sentences. It is shown that this explains the universal and existential character of Universal- and NPI-any, respectively, and the positive and negative contexts in which they are licensed. Our uniform analysis extends to the use of any in command and permission sentences. It predicts that (...)

    Notes.Robert van Rooij - unknown
    Definition 1. A Strict partial order is a structure X, P , with P a binary relation on X that is irreflexive (IR) and Transitive (TR): (IR) ∀x : ¬P (x, x). (TR) ∀x, y, v, w : (P (x, y) ∧ P (y, z)) → P (x, z).
