    Inquisitive Semantics.Ivano Ciardelli, Jeroen Groenendijk & Floris Roelofsen - 2018 - Oxford, England: Oxford University Press.
    The book presents a new logical framework to capture the meaning of sentences in conversation. It is based on a richer notion of meaning than traditional approaches, and allows for an integrated treatment of statements and questions. The first part of the book presents the framework in detail, while the second demonstrates its many benefits.

  2. Two Switches in the Theory of Counterfactuals: A Study of Truth Conditionality and Minimal Change.Ivano Ciardelli, Linmin Zhang & Lucas Champollion - 2018 - Linguistics and Philosophy (6).
    Based on a crowdsourced truth value judgment experiment, we provide empirical evidence challenging two classical views in semantics, and we develop a novel account of counterfactuals that combines ideas from inquisitive semantics and causal reasoning. First, we show that two truth-conditionally equivalent clauses can make different semantic contributions when embedded in a counterfactual antecedent. Assuming compositionality, this means that the meaning of these clauses is not fully determined by their truth conditions. This finding has a clear explanation in inquisitive semantics: (...)

    Inquisitive Logic.Ivano Ciardelli & Floris Roelofsen - 2011 - Journal of Philosophical Logic 40 (1):55-94.
    This paper investigates a generalized version of inquisitive semantics. A complete axiomatization of the associated logic is established, the connection with intuitionistic logic and several intermediate logics is explored, and the generalized version of inquisitive semantics is argued to have certain advantages over the system that was originally proposed by Groenendijk (2009) and Mascarenhas (2009).

  4. Inquisitive Dynamic Epistemic Logic.Ivano A. Ciardelli & Floris Roelofsen - 2015 - Synthese 192 (6):1643-1687.
    Information exchange can be seen as a dynamic process of raising and resolving issues. The goal of this paper is to provide a logical framework to model and reason about this process. We develop an inquisitive dynamic epistemic logic , which enriches the standard framework of dynamic epistemic logic , incorporating insights from recent work on inquisitive semantics. At a static level, IDEL does not only allow us to model the information available to a set of agents, like standard epistemic (...)

    Indicative Conditionals and Graded Information.Ivano Ciardelli - 2020 - Journal of Philosophical Logic 49 (3):509-549.
    I propose an account of indicative conditionals that combines features of minimal change semantics and information semantics. As in information semantics, conditionals are interpreted relative to an information state in accordance with the Ramsey test idea: “if p then q” is supported at a state s iff q is supported at the hypothetical state s[p] obtained by restricting s to the p-worlds. However, information states are not modeled as simple sets of worlds, but by means of a Lewisian system of (...)

    Composing Alternatives.Ivano Ciardelli, Floris Roelofsen & Nadine Theiler - 2017 - Linguistics and Philosophy 40 (1):1-36.
    There is a prominent line of work in natural language semantics, rooted in the work of Hamblin, in which the meaning of a sentence is not taken to be a single proposition, but rather a set of propositions—a set of alternatives. This allows for a more fine-grained view on meaning, which has led to improved analyses of a wide range of linguistic phenomena. However, this approach also faces a number of problems. We focus here on two of these, in our (...)

    Questions as Information Types.Ivano Ciardelli - 2018 - Synthese 195 (1):321-365.
    This paper argues that questions have an important role to to play in logic, both semantically and proof-theoretically. Semantically, we show that by generalizing the classical notion of entailment to questions, we can capture not only the standard relation of logical consequence, which holds between pieces of information, but also the relation of logical dependency, which holds between information types. Proof-theoretically, we show that questions may be used in inferences as placeholders for arbitrary information of a given type; by manipulating (...)

    On the Semantics and Logic of Declaratives and Interrogatives.Ivano Ciardelli, Jeroen Groenendijk & Floris Roelofsen - 2015 - Synthese 192 (6):1689-1728.
    In many natural languages, there are clear syntactic and/or intonational differences between declarative sentences, which are primarily used to provide information, and interrogative sentences, which are primarily used to request information. Most logical frameworks restrict their attention to the former. Those that are concerned with both usually assume a logical language that makes a clear syntactic distinction between declaratives and interrogatives, and usually assign different types of semantic values to these two types of sentences. A different approach has been taken (...)

    Questions and Dependency in Intuitionistic Logic.Ivano Ciardelli, Rosalie Iemhoff & Fan Yang - 2020 - Notre Dame Journal of Formal Logic 61 (1):75-115.
    In recent years, the logic of questions and dependencies has been investigated in the closely related frameworks of inquisitive logic and dependence logic. These investigations have assumed classical logic as the background logic of statements, and added formulas expressing questions and dependencies to this classical core. In this paper, we broaden the scope of these investigations by studying questions and dependency in the context of intuitionistic logic. We propose an intuitionistic team semantics, where teams are embedded within intuitionistic Kripke models. (...)

    Hurford’s Constraint, the Semantics of Disjunction, and the Nature of Alternatives.Ivano Ciardelli & Floris Roelofsen - 2017 - Natural Language Semantics 25 (3):199-222.
    This paper contributes to two recent lines of work on disjunction: on the one hand, work on so-called Hurford disjunctions, i.e., disjunctions where one disjunct entails another, and on the other hand, work in alternative and inquisitive semantics where disjunction has been argued to generate multiple propositional alternatives. We point out that Hurford effects are found not only in disjunctive statements, but also in disjunctive questions. These cases are not covered by the standard accounts of Hurford phenomena, which assume a (...)

    Why We Need a Question Semantics.Ivano Ciardelli - 2021 - In Moritz Cordes (ed.), Asking and Answering: Rivalling Approaches to Interrogative Methods. Tübingen: Narr Francke Attempto. pp. 15–47.
    In this paper I discuss the role that question contents should play in an overall account of language, thought, and communication. Based on these considerations, I argue against the Fregean view that analyzes questions as distinguished only at the level of force. Questions, I argue, are associated with specific semantic objects, which play a distinctive role in thought and in compositional semantics, stand in logical relations to one another, and can act as contents of multiple speech acts. In the second (...)

  12. Breaking de Morgan's Law in Counterfactual Antecedents.Lucas Champollion, Ivano Ciardelli & Linmin Zhang - manuscript
    The main goal of this paper is to investigate the relation between the meaning of a sentence and its truth conditions. We report on a comprehension experiment on counterfactual conditionals, based on a context in which a light is controlled by two switches. Our main finding is that the truth-conditionally equivalent clauses (i) "switch A or switch B is down" and (ii) "switch A and switch B are not both up" make different semantic contributions when embedded in a conditional antecedent.

    Inquisitive Bisimulation.Ivano Ciardelli & Martin Otto - 2021 - Journal of Symbolic Logic 86 (1):77-109.
    Inquisitive modal logic, InqML, is a generalisation of standard Kripke-style modal logic. In its epistemic incarnation, it extends standard epistemic logic to capture not just the information that agents have, but also the questions that they are interested in. Technically, InqML fits within the family of logics based on team semantics. From a model-theoretic perspective, it takes us a step in the direction of monadic second-order logic, as inquisitive modal operators involve quantification over sets of worlds. We introduce and investigate (...)

    Question Meaning= Resolution Conditions.Ivano Ciardelli - 2017 - Logic and Logical Philosophy 26 (3):383-416.
    Traditional approaches to the semantics of questions analyze questions indirectly, via the notion of an answer. In recent work on inquisitive semantics, a different perspective is taken: the meaning of a question is equated with its resolution conditions, just like the meaning of a statement is traditionally equated with its truth-conditions. In this paper I argue that this proposal improves on previous approaches, combining the formal elegance and explanatory power of Groenendijk and Stokhof’s partition theory with the greater generality afforded (...)

    The restrictor view, without covert modals.Ivano Ciardelli - 2022 - Linguistics and Philosophy 45 (2):293-320.
    The view that if-clauses function semantically as restrictors is widely regarded as the only candidate for a fully general account of conditionals. The standard implementation of this view assumes that, where no operator to be restricted is in sight, if-clauses restrict covert epistemic modals. Stipulating such modals, however, lacks independent motivation and leads to wrong empirical predictions. In this paper I provide a theory of conditionals on which if-clauses are uniformly interpreted as restrictors, but no covert modals are postulated. Epistemic (...)

    Games and Cardinalities in Inquisitive First-Order Logic.Ivano Ciardelli & Gianluca Grilletti - forthcoming - Review of Symbolic Logic:1-28.
    Inquisitive first-order logic, InqBQ, is a system which extends classical first-order logic with formulas expressing questions. From a mathematical point of view, formulas in this logic express properties of sets of relational structures. This paper makes two contributions to the study of this logic. First, we describe an Ehrenfeucht–Fraïssé game for InqBQ and show that it characterizes the distinguishing power of the logic. Second, we use the game to study cardinality quantifiers in the inquisitive setting. That is, we study what (...)

    Intuitionistic Conditional Logics.Ivano Ciardelli & Xinghan Liu - 2020 - Journal of Philosophical Logic 49 (4):807-832.
    Building on recent work by Yale Weiss, we study conditional logics in the intuitionistic setting. We consider a number of semantic conditions which give rise, among others, to intuitionistic counterparts of Lewis’s logic VC and Stalnaker’s C2. We show how to obtain a sound and complete axiomatization of each logic arising from a combination of these conditions. On the way, we remark how, in the intuitionistic setting, certain classically equivalent principles of conditional logic come apart, and how certain logical connections (...)

    The Dynamic Logic of Stating and Asking.Ivano Ciardelli - 2017 - In Alexandru Baltag, Jeremy Seligman & Tomoyuki Yamada (eds.), Logic, Rationality, and Interaction. LORI 2017. Springer. pp. 240-255.
    Inquisitive dynamic epistemic logic extends standard public announcement logic incorporating ideas from inquisitive semantics. In IDEL, the standard public announcement action can be extended to a more general public utterance action, which may involve a statement or a question. While uttering a statement has the effect of a standard announcement, uttering a question typically leads to new issues being raised. In this paper, we investigate the logic of this general public utterance action. We find striking commonalities, and some differences, with (...)
