Borsboom and colleagues have recently proposed a “network theory” of psychiatric disorders that conceptualizes psychiatric disorders as relatively stable networks of causally interacting symptoms. They have also claimed that the network theory should include non-symptom variables such as environmental factors. How are environmental factors incorporated in the network theory, and what kind of explanations of psychiatric disorders can such an “extended” network theory provide? The aim of this article is to critically examine what explanatory strategies the network theory that includes (...) both symptoms and environmental factors can accommodate. We first analyze how proponents of the network theory conceptualize the relations between symptoms and between symptoms and environmental factors. Their claims suggest that the network theory could provide insight into the causal mechanisms underlying psychiatric disorders. We assess these claims in light of network analysis, Woodward’s interventionist theory, and mechanistic explanation, and show that they can only be satisfied with additional assumptions and requirements. Then, we examine their claim that network characteristics may explain the dynamics of psychiatric disorders by means of a topological explanatory strategy. We argue that the network theory could accommodate topological explanations of symptom networks, but we also point out that this poses some difficulties. Finally, we suggest that a multilayer network account of psychiatric disorders might allow for the integration of symptoms and non-symptom factors related to psychiatric disorders and could accommodate both causal/mechanistic and topological explanations.

In this volume, Geurts takes discourse representation theory (DRT), and turns it into a unified account of anaphora and presupposition, which he applies not only to the standard problem cases but also to the interpretation of modal expressions, attitude reports, and proper names. The resulting theory, for all its simplicity, is without doubt the most comprehensive of its kind to date. The central idea underlying Geurts' 'binding theory' of presupposition is that anaphora is just a special case of (...) presupposition projection. But this is only one of the ways in which the concept of presupposition is taken beyond its traditional limits. Geurts shows, furthermore, that presupposition projection is crucially involved in several phenomena that are not usually viewed in presuppositional terms, such as modal subordination, de re readings of attitude reports, and rigid designation. While making his case for DRT and the binding theory, Geurts also presents an incisive analysis of what is probably still the most influential account of presupposition, viz. the satisfaction theory, demonstrating that there are fundamental problems not only with this theory but with the very framework in which it is couched.

This is an attempt at reviving Kneale's version of the description theory of names, which says that a proper name is synonymous with a definite description of the form ‘the individual named so-and-so’. To begin with, I adduce a wide range of observations to show that names and overt definites are alike in all relevant respects. I then turn to Kripke's main objection against Kneale's proposal, and endeavour to refute it. In the remainder of the paper I elaborate on Kneale's (...) analysis, adopting a theory of presupposition proposed by van der Sandt. (shrink)

This paper is devoted to the formulation and investigation of a dynamic semantic interpretation of the language of first-order predicate logic. The resulting system, which will be referred to as ‘dynamic predicate logic’, is intended as a first step towards a compositional, non-representational theory of discourse semantics. In the last decade, various theories of discourse semantics have emerged within the paradigm of model-theoretic semantics. A common feature of these theories is a tendency to do away with the principle of compositionality, (...) a principle which, implicitly or explicitly, has dominated semantics since the days of Frege. Therefore the question naturally arises whether non-compositionality is in any way a necessary feature of discourse semantics. Since we subscribe to the interpretation of compositionality as constituting primarily a methodological principle, we consider this to be a methodological rather than an empirical question. As a consequence, the emphasis in the present paper lies on developing an alternative compositional semantics of discourse, which is empirically equivalent to its non-compositional brethren, but which differs from them in a principled methodological way. Hence, no attempts are made to improve on existing theories empirically. Nevertheless, as we indicate in section 5, the development of a compositional alternative may in the end have empirical consequences, too. First of all, it can be argued that the dynamic view on interpretation developed in this paper suggests natural and relatively easy to formulate extensions which enable one to deal with a wider range of phenomena than can be dealt with in existing theories. Moreover, the various approaches to the model-theoretic semantics of discourse that have been developed during the last decade, have constituted a ‘fresh start’ in the sense that much of what had been accomplished before was ignored, at least for a start. Of course, this is a justified strategy if one feels one is trying to develop a radically different approach to recalcitrant problems. However, there comes a time when such new approaches have to be compared with the older one, and when an assessment of the pros and cons of each has to be made. One of the main problems in semantics today, we feel, is that a semantic theory such as Montague grammar, and an approach like Kamp’s discourse representation theory, are hard to compare, let alone that it is possible to unify their insights and results..

Conditional sentences with quantifying expressions are systematically ambigous. In one reading, the if -clause restricts the domain of the overt quantifier; in the other, the if -clause restricts the domain of a covert quantifier, which defaults to epistemic necessity. Although the ambiguity follows directly from the Lewis- Kratzer line on if, it is not generally acknowledged, which has led to pseudoproblems and spurious arguments.

Abstract: The Gricean theory of conversational implicature has always been plagued by data suggesting that what would seem to be conversational inferences may occur within the scope of operators like believe , for example; which for bona fide implicatures should be an impossibility. Concentrating my attention on scalar implicatures, I argue that, for the most part, such observations can be accounted for within a Gricean framework, and without resorting to local pragmatic inferences of any kin d. However, there remains a (...) small class of marked cases that cannot be treated as conversational implicatures, and they do require a local mode of pragmatic interpretation. (shrink)

There is a wealth of experimental data showing that the way a problem is framed may have an effect on people's choices and decisions. Based on a semantic analysis of evaluative expressions like ‘good’, I propose a new explanation of such framing effects. The key idea is that our choices and decisions reveal a counterfactual systematicity: they carry information about the choices and decisions we would have made if the facts had been otherwise. It is these counterfactual alternatives that may (...) diverge between otherwise equivalent versions of the same task, and thus explain the effects of framing. (shrink)

The power of technology to transform religions, science, and political institutions has often been presented as nothing short of revolutionary. Does technology have a similarly transformative influence on societies’ morality? Scholars have not rigorously investigated the role of technology in moral revolutions, even though existing research on technomoral change suggests that this role may be considerable. In this paper, we explore what the role of technology in moral revolutions, understood as processes of radical group-level moral change, amounts to. We do (...) so by investigating four historical episodes of radical moral change in which technology plays a noteworthy role. Our case-studies illustrate the plurality of mechanisms involved in technomoral revolutions, but also suggest general patterns of technomoral change, such as technology’s capacity to stabilize and destabilize moral systems, and to make morally salient phenomena visible or invisible. We find several leads to expand and refine conceptual tools for analysing moral change, specifically by crystallizing the notions of ‘technomoral niche construction’ and ‘moral payoff mechanisms’. Coming to terms with the role of technology in radical moral change, we argue, enriches our understanding of moral revolutions, and alerts us to the depths of which technology can change our societies in wanted and unwanted ways.

Conventions are regularities in social behaviour of the past that enable us to coordinate our actions. Some conventions are lawlike: they are expected to be observed always or nearly always. However, in order to coordinate our actions, it may suffice that a precedent has occurred often enough, and sometimes even a single precedent will do. So, in general, conventions merely enable us to solve our coordination problems; lawlike conventions are a special case. Grammatical conventions are often lawlike; sense conventions are (...) typically enabling. In order to resolve the indeterminacies that sense conventions give rise to, interlocutors must rely on the common ground. In this and other ways, common ground is a prerequisite for convention‐based communication. (shrink)

Extensive overview and critical analysis of various approaches to the semantics of questions.

Gricean pragmatics has often been criticised for being implausible from a psychological point of view. This line of criticism is never backed up by empirical evidence, but more importantly, it ignores the fact that Grice never meant to advance a processing theory, in the first place. Taking our lead from Marr, we distinguish between two levels of explanation: at the W-level, we are concerned with what agents do and why; at the H-level, we ask how agents do whatever it is (...) they do. Whereas pragmatics is pitched at the W-level, processing theories are at the H-level. This is not to say that pragmatics has no implications for psychology at all, but it is to say that its implications are less direct than is often supposed. (shrink)

People talk not only to others but also to themselves. The self talk we engage in may be overt or covert, and is associated with a variety of higher mental functions, including reasoning, problem solving, planning and plan execution, attention, and motivation. When talking to herself, a speaker takes devices from her mother tongue, originally designed for interpersonal communication, and employs them to communicate with herself. But what could it even mean to communicate with oneself? To answer that question, we (...) need a theory of communication that explains how the same linguistic devices may be used to communicate with others and oneself. On the received view, which defines communication as information exchange, self talk appears to be an anomaly, for it is hard to see the point of exchanging information with oneself. However, if communication is analysed as a way of negotiating commitments between speaker and hearer, then communication may be useful even when speaker and hearer coincide. Thus a commitment-based approach allows us to make sense of self talk as well as social talk. (shrink)

In the semantics of natural language, quantification may have received more attention than any other subject, and one of the main topics in psychological studies on deductive reasoning is syllogistic inference, which is just a restricted form of reasoning with quantifiers. But thus far the semantical and psychological enterprises have remained disconnected. This paper aims to show how our understanding of syllogistic reasoning may benefit from semantical research on quantification. I present a very simple logic that pivots on the monotonicity (...) properties of quantified statements - properties that are known to be crucial not only to quantification but to a much wider range of semantical phenomena. This logic is shown to account for the experimental evidence available in the literature as well as for the data from a new experiment with cardinal quantifiers ("at least n" and "at most n"), which cannot be explained by any other theory of syllogistic reasoning.

In this paper we study the admissible rules of intermediate logics. We establish some general results on extensions of models and sets of formulas. These general results are then employed to provide a basis for the admissible rules of the Gabbay–de Jongh logics and to show that these logics have finitary unification type.

Abstract:The introduction of the kilometer in nineteenth-century Europe, within a context of broader processes of standardization and capitalism and the proliferation of maps and railways, has been associated with the disembodiment, deindividuation and decontextualization of travel. This article offers a critique of this notion by examining the various meanings different units of distance had for travelers; to what extent these units were related to the body and the physical activity of travel; and whether these relations changed between the 1770s and (...) 1910s. Focusing on texts of instruction and texts about travelers' own journeys, written in the Dutch, German, English and French languages, the article argues that a number of more embodied ways of describing distances survived alongside more standardized measures.

It is well known that most is not first-order definable, and that the proof is in Barwise and Cooper’s 1981 paper. Actually, Barwise and Cooper present two theorems that bear on the issue. Their theorem C12 says that, for any pair of one-place predicates A and B, there is no sentence of classical predicate logic that is true iff ‘Most A are B’ is. (I assume that ‘Most A are B’ means that more than half of the A’s are B, (...) but the only thing that matters is that most is proportional.) Barwise and Cooper’s C13 states that the foregoing result remains valid when classical logic is enriched with a unary quantifier Q so defined that Qx(Ax) is true iff more than half of the entities in the domain of quantification are A’s.

One of the more persistent debates in mereology is whether distinct wholes can have the same parts. Extensional mereologists hold that if there is no part that makes the difference, then there is nothing to distinguish the wholes, so sameness of parts implies identity. Non-extensionalists, however, do think there are cases where distinct wholes share all their parts. This paper argues that the kind of argument non-extensionalists employ can also be levelled against a widely accepted extensionality principle of plural logic. (...) Non-extensionalists thus face a dilemma: either give up the argument for non-extensional mereology, or deny both the extensionality principle of mereology and the analogous principle for plural logic.

The T.S. Eliot of the 1920s was a European humanist who was part of an international network of like-minded intellectuals. Their ideas about literature, education and European culture in general remain highly relevant to the cultural debates of our day.

It appears that in mixed quotations like the following, the quoted expression is used and mentioned at the same time: (1) George says Tony is his ``bestest friend''. Most theories seek to account for this observation by assuming that mixed quotations operate at two levels of content at once. In contradistinction to such two-dimensional theories, we propose that quotation involves just a single level of content. Quotation always produces a change in meaning of the quoted expression, and if the quotation (...) is mixed the shift is, to a first approximation at least, from '...' to ``what x calls '...''', where x is a variable whose value is determined by the context. We argue that quotation is generally context dependent in various ways, and that some of these ways are presuppositional in nature; we present a detailed analysis of the presuppositions in question.

This paper consists of two main parts and a coda. In the first part I present the ''binding theory'' of presupposition projection, which is the framework that I adopt in this paper (Section 1.1). I outline the main problems that arise in the interplay between presuppositions and anaphors on the one hand and attitude reports on the other (Section 1.2), and discuss Heim''s theory of presuppositions in attitude contexts (Section 1.3).In the second part of the paper I present my own (...) proposal. To begin with, I define an extension of DRT in which attitude reports can be represented (Sections 2.1–2.2). I then argue that the verb believe triggers a certain presupposition and that, given the binding theory, this presupposition determines the projection behaviour of the verb (Section 2.3). This analysis yields predictions which are incomplete in the sense that they do not fully account for speakers'' intuitions about presuppositions and anaphors in belief contexts. In Section 2.4 I suggest that this is as it should be because we may assume on independent grounds that there is a class of plausibility inferences which complement the predictions of the presupposition theory. Finally, the analysis is extended to the verb want (Section 2.5). (shrink)

Linguistic research has revealed several pathways of language change that may guide our understanding of the evolution of mental‐state attribution. In particular, it turns out that, in many languages, quotative verbs have been exapted for attributing a variety of mental states, including beliefs and intentions. In such languages, the literal translation of, “Betty said: ‘There will be war’”, may be used not only to quote Betty's words, but also to convey that she thought or intended there to be war. This (...) paper presents a model of the pragmatic shifts underlying this pathway, and proposes an evolutionary trajectory from quotation to the public practice of attributing beliefs and intentions, and thence to implicit belief/intention attribution.

This paper presents an analysis of wh-complements in Montague Grammar. We will be concerned primarily with semantics, though some remarks on syntax are made in Section 4. Questions and wh-comple ments in Montague Grammar have been studied in Hamblin (1976), Bennett (1979), Karttunen (1977) and Hauser (1978) among others. These proposals will not be discussed explicitly, but some differences with Karttunen's analysis will be pointed out along the way.

Scholarly discourse on “disruptive technologies” has been strongly influenced by disruptive innovation theory. This theory is tailored for analyzing disruptions in markets and business. It is of limited use, however, in analyzing the broader social, moral and existential dynamics of technosocial disruption. Yet these broader dynamics should be of great scholarly concern, both in coming to terms with technological disruptions of the past and those of our current age. Technologies can disrupt social relations, institutions, epistemic paradigms, foundational concepts, values, and (...) even the nature of human cognition and experience – domains of disruption that are largely neglected in existing discourse on disruptive technologies. Accordingly, this paper seeks to reorient scholarly discussion around a broader notion of technosocial disruption. This broader notion raises three foundational questions. First, how can technosocial disruption be conceptualized in a way that clearly sets it apart from the disruptive innovation framework? Secondly, how does the notion of technosocial disruption relate to the concordant notions of “disruptor” and “disruptiveness”? Thirdly, can we advance criteria to assess the “degree of social disruptiveness” of different technologies? The paper clarifies these questions and proposes an answer to each of them. In doing so, it advances “technosocial disruption” as a key analysandum for future scholarship on the interactions between technology and society. (shrink)

In this paper I present experimental data showing that the interpretation of donkey sentences is influenced by certain aspects of world knowledge that seem to elude introspective observation, which I try to explain by reference to a scale ranging from prototypical individuals (like children) to quite marginal ones (such as railway lines). This ontological cline interacts with the semantics of donkey sentences: as suggested already by the anecdotal data on which much of the literature is based, the effect of world (...) knowledge is by and large restricted to donkey sentences with non-intersective determiners. I outline a psychological model which incorporates both ontological and logical factors, and suggest that there may be something wrong with the standard assumption that a statement's receiving a truth value requires that it have a definite reading.

Over the course of human history there appears to have been a global shift in moral values towards a broadly ‘liberal’ orientation. Huemer argues that this shift better accords with a realist than an antirealist metaethics: it is best explained by the discovery of mind-independent truths through intuition. In this article I argue, contra Huemer, that the historical data are better explained assuming the truth of moral antirealism. Realism does not fit the data as well as Huemer suggests, whereas antirealists (...) have underappreciated resources to explain the relevant historical dynamics. These resources include an appeal to socialization, to technological and economical convergences, to lessons learned from history, to changes induced by consistency reasoning and to the social function of moral norms in overcoming some of the cooperation problems that globalizing societies face. I point out that the realist’s explanans has multiple shortcomings, that the antirealist’s explanans has several explanatory virtues, and conclude that the latter provides a superior account of the historical shift towards liberal values.

The Visser rules form a basis of admissibility for the intuitionistic propositional calculus. We show how one can characterize the existence of covers in certain models by means of formulae. Through this characterization, we provide a new proof of the admissibility of a weak form of the Visser rules. Finally, we use this observation, coupled with a description of a generalization of the disjunction property, to provide a basis of admissibility for the intermediate logics BD2 and GSc.

Like David Silver before them, Erik Baldwin and Michael Thune argue that the facts of religious pluralism present an insurmountable challenge to the rationality of basic exclusive religious belief as construed by Reformed Epistemology. I will show that their argument is unsuccessful. First, their claim that the facts of religious pluralism make it necessary for the religious exclusivist to support her exclusive beliefs with significant reasons is one that the reformed epistemologist has the resources to reject. Secondly, they fail to (...) demonstrate that it is impossible for basic religious beliefs to return to their properly basic state after defeaters against them have been defeated. Finally, I consider whether there is perhaps a similar but better argument in the neighbourhood and conclude in the negative. Reformed Epistemology's defence of exclusivism thus remains undefeated.

Joint attention customarily refers to the coordinated focus of attention between two or more individuals on a common object or event, where it is mutually “open” to all attenders that they are so engaged. We identify two broad approaches to analyse joint attention, one in terms of cognitive notions like common knowledge and common awareness, and one according to which joint attention is fundamentally a primitive phenomenon of sensory experience. John Campbell’s relational theory is a prominent representative of the latter (...) approach, and the main focus of this paper. We argue that Campbell’s theory is problematic for a variety of reasons, through which runs a common thread: most of the problems that the theory is faced with arise from the relational view of perception that he endorses, and, more generally, they suggest that perceptual experience is not sufficient for an analysis of joint attention.

The meta-ethical commitments of folk respondents – specifically their commitment to the objectivity of moral claims – have recently become subject to empirical scrutiny. Experimental findings suggest that people are meta-ethical pluralists: There is both inter- and intrapersonal variation with regard to people’s objectivist commitments. What meta-ethical implications, if any, do these findings have? I point out that current research does not directly address traditional meta-ethical questions: The methods used and distinctions drawn by experimenters do not perfectly match those of (...) meta-ethicists. However, I go on to argue that, in spite of this mismatch, the research findings should be of interest to moral philosophers, including meta-ethicists. Not only do these findings extend the field of moral psychology with new data and hypotheses, but they also provide tentative evidence that touches on the adequacy of theses in moral semantics and moral metaphysics. Specifically, they put pressure on argum... (shrink)

The information conveyed by any utterance is a motley ensemble. Utterances carry content about the world as it is according to the speaker, but also about speakers’ attitudes, the way they speak, what has been said before, and so on. There are many kinds of information that are conveyed by way of language, and differences in kind correlate with differences in status. Presupposed information exhibits a distinctive projection behaviour; conversational implicatures are cancellable in a way that asserted information is not; (...) a pronoun’s gender may help to determine a referent, but is otherwise truth-conditionally inert; and so on.

Corporate governance (CG) is a key area of management with important implications for business ethics. The interface of CG and business ethics is populated with rich intellectual debates on the role of ethics in governance from a multi-disciplinary perspective. Within these debates, the relationship between CG and outcomes for business and society, and the role of CG structures and processes and their comparative aspects across institutional settings are discussed. Despite a proliferation of research at the interface of CG and ethics, (...) we observe that an engagement with topics, methodologies, and expected outcomes drawing on established frames and theories of CG tends to the ignoring or even the preclusion of an explicit engagement with debates in business ethics. Through this VSI, we as section editors showcase previously published papers in the Journal that proactively explore the explicit linkages and interfaces between CG and ethical societal challenges, with the aim of inspiring further such CG research.

Spacing between study trials of an item increases the probability that item will be recalled. This article presents a new model for spacing based on the SAM theory of memory developed by Raaijmakers and Shiffrin (1980, 1981). The model is a generalization of the SAM model as applied to interference paradigms (Mensink & Raaijmakers, 1988, 1989) and may be viewed as a mathematical version of the Component‐Levels theory proposed by Glenberg (1979). It is assumed that on a second presentation of (...) an item, information is added to an existing trace if the episodic memory image corresponding to that item is retrieved. If it is not retrieved, a new image is stored. It is shown that the model predicts many standard findings including the lack of a spacing effect for the recall of at least one of two items each presented once (Ross & Landauer, 1978). (shrink)
