According to relevance theory, irony comprehension invariably entails the identification of some opinion or thought and the identification of the speaker’s dissociative attitude. In this paper, it is argued that it is also essential for hearers to identify not only that propositional attitude, but also the affective attitude that the speaker holds towards the source of this echo so that an optimallyrelevant interpretive outcomeis achieved. This notion comprises feelings and emotions of a non-propositional quality which affect the (...) class='Hi'>propositional effects obtained in ironical communication. The paper further argues for the need to incorporate non-propositional effects into the traditional propositional object of pragmatic research. (shrink)

Two arguments are discussed which have been advanced in support of eliminative materialism: the argument from reductionism and the argument from functionalism. It is contended that neither of these arguments is effective if "non-scientific realism" is adopted with regard to commonsense propositional attitude psychology and its embedded notions. "Non-scientific realism," the position that commonsense propositional attitude psychology is an independently legitimate descriptive/explanatory framework, neither in competition with science nor vulnerable to being shown false by science, is defended.

In order to resolve the controversial discussion regarding content effects in deductive reasoning, we propose distinguishing between two inferential sources—an argument's form , and additional relations people associate with the argument's content —and analysing their interplay. Both sources are equally necessary in order to understand the role content plays in deductive reasoning. People make valid deductions from the content relations ( content competence ), but in thematic reasoning tasks, these deductions lead to the intriguing phenomenon known as content (...) class='Hi'>effects . Focusing on the interplay of both sources of inferences, the dual source distinction enables a novel class of predictions to be made, namely the correct mastery of the logical connectors ( form competence ) in tasks that require the individual to think about an argument's form in relation to its content. To illustrate the dual source approach and its implications, the selection task paradigm of conditional reasoning with a point of view is used in combination with two content domains: conditional promises with cheating and non-cheating perspectives and technical systems with causal perspectives. Experimental findings corroborate all three phenomena: content competence, content effects, and form competence. The dual source distinction is discussed with regard to current theories of reasoning.

Deirdre Wilson (2018)provides a reflective overview of a volume devoted to the historic application of relevance-theoretic ideas to literary studies. She maintains a view argued elsewhere that the putative non-propositional nature of (among other things) literary effects are an illusion, a view which dates to Sperber and Wilson (1986/1995: 224): “If you look at [non-propositional] affective effects through the microscope of relevance theory, you see a wide array of minute cognitive [i.e., propositional] effects.” This (...) paper suggests an alternative, that modern-day humans have two apparently different modes of expressing and interpreting information: one of these is a system in which propositional, cognitive effects dominate; the other involves direct, non-propositional effects. The paper concludes by describing two ways such affects might be assimilated into relevance theory. The first, to accept that humans are much more than merely cognitive organisms; the second, to rethink quite radically what we mean by cognition. (shrink)

Metaphor is a pervasive and significant feature of language. We use metaphor to talk about the world in familiar and innovative ways, and in contexts ranging from everyday conversation to literature and scientific theorizing. However, metaphor poses serious challenges for standard philosophical theories of meaning, because it straddles so many important boundaries: between language and thought, between semantics and pragmatics, between rational communication and mere causal association. ;In this dissertation, I develop a pragmatic theory of metaphorical utterances which reconciles two (...) apparently incompatible intuitions. The first is that metaphors are vehicles for undertaking speech acts with a propositional content distinct from their conventional sentence meaning. The second is that metaphors are tools for inducing the essentially non-propositional effect of 'seeing things in a new light' or under a new aspect. These intuitions seem to be incompatible because it is assumed that only one can capture the essential function of metaphor. I propose instead that non-propositional 'seeing-as' or aspectual thought serves as the means by which speakers intend to accomplish their end of communicating content. This does not imply that speakers are not interested in and even committed to the effects of aspectual thought as well, only that it is not their sole, ultimate intention. ;In order to substantiate this proposal about how metaphor works, I develop an account of the psychological structures on which aspectual thought operates and the changes it engenders; I then show how the content of the speaker's intended speech act is determined by the aspect the sentence generates. By bringing propositional content and non-propositional aspectual thought together in this way, my account can treat the full range of metaphors, from 'ordinary' to 'poetic', within a unified theory. Armed with this account, we have the explanatory resources necessary to acknowledge both that ordinary conversational metaphors are efficient and sometimes essential vehicles for communicating determinate propositional contents, and also that rich, poetic metaphors are invitations to an open-ended contemplation of the subject under discussion. These apparently very different effects turn out to be manifestations of the same basic process of comprehension. (shrink)

Compound propositions which can successfully be defended in a quantumdialogue independent of the elementary propositions contained in it, must have this property also independent of the mutual elementary commensur-abilities. On the other hand, formal commensurabilities must be taken into account. Therefore, for propositions which can be proved by P, irrespective of both the elementary propositions and of the elementary commensur-abilities, there exists a formal strategy of success. The totality of propositions with a formal strategy of success in a quantum dialogue (...) form the effective quantum logic. The propositions of the effective quantum logic can be derived from a calculus Q eff which is — on the other hand — equivalent to a lattice L qi.Propositions about measuring results are above all time dependent propositions A(S;t). In a dialogue, different partial propositions will have in general different time values. If one can (accidentally) win a material dialogue, this dialogue can be related to a single time value. For the propositions of the effective quantum logic there exist formal strategies of success, independent of the elementary propositions contained in it. All partial propositions appearing in the dialogue are formally commensurable. Therefore the propositions of effective quantum logic which can be proved by formal dialogues can always be related to a single time. They present a description of the system S considered in which all partial propositions can be related jointly to the state of S.Therefore in the effective quantum logic we have — in the limit of equal time values — a situation which corresponds conceptually to the description of the system (S; ψ) in Hilbert space. Consequently, one would expect that also the lattice L qi — except from the tertium non datur 8 — agrees with the lattice L q of subspaces of Hilbert space. It has been shown that these lattices are in fact isomorphic. (shrink)

In line with recent interest in weak and often not fully determinate effects of communication permeating relevance-theoretic research, I contribute a discussion on two possible sources of speaker-intended indeterminacy within explicit import of an utterance: one residing in an intentionally underspecified location of an ad hoc concept between literal or non-literal (e.g. metaphorical or hyperbolic) interpretation, and the other lying in the higher-level explicature of an utterance, and being related to propositional attitude (e.g. pretence, reporting, dissociation) or speech-act (...) description (e.g. complementing, reproaching). In both cases, the speaker leaves a certain amount of indeterminacy concerning the degree of her commitment to the content communicated, by not indicating where precisely the concept or the attitude is to be located on the literalness-metaphor continuum or on the continuum of various propositional attitudes/speech-act descriptions, respectively. Using a number of illustrative examples drawn from television discourse, I try to show that this kind of intended indeterminacy gives rise to communicative effects of a non-propositional kind. Additionally, the analyses presented here support the deflationary view of figurative uses of language, on which they form continua with non-figurative utterances. (shrink)

A general mathematical framework, based on countable partitions of Natural Numbers [1], is presented, that allows to provide a Semantics to propositional languages. It has the particularity of allowing both the valuations and the interpretation Sets for the connectives to discriminate complexity of the formulas. This allows different adequacy criteria to be used to assess formulas associated with the same connective, but that differ in their complexity. The presented method can be adapted potentially infinite number of connectives and truth (...) values, therefore, it can be considered a general framework to provide semantics to several of the known logic systems (eg, LC, L3 LP, FDE). The presented semantics allow to converge to different standard semantics if the separation complexity procedure is annulled. Therefore, it can be understood as a framework that allows greater precision (in complexity terms) with respect to formula satisfaction. Naturally, because of how it is built, it can be incorporated into non-deterministic semantics. The presented procedure also allows generating valuations that grant a different truth value to each formula of propositional language. As a positive side effect, our method allows a constructive proof of the equipotence between N and N^n for all Natural n. (shrink)

We introduce a Gentzen style formulation of Basic Propositional Calculus(BPC), the logic that is interpreted in Kripke models similarly tointuitionistic logic except that the accessibility relation of eachmodel is not necessarily reflexive. The formulation is presented as adual-context style system, in which the left hand side of a sequent isdivided into two parts. Giving an interpretation of the sequents inKripke models, we show the soundness and completeness of the system withrespect to the class of Kripke models. The cut-elimination theorem (...) isproved in a syntactic way by modifying Gentzen's method. Thisdual-context style system exemplifies the effectiveness of dual-contextformulation in formalizing various non-classical logics. (shrink)

Gender-based Violence is a huge concern in many African countries such as Zimbabwe despite the preventative and mitigatory interventions that have been proposed and implemented by various stakeholders. The interventions applied range from policies and programmes that are government initiated as well as those interventions by social actors such as non-government organisations and Faith-based Organisations like churches. Gender-based violence as a social structural issue is sustained and perpetuated by cultural norms, values and beliefs that are fed by patriarchy, among other (...) things. To effectively respond to the situation, interventions should target multiple social levels, including policy, government officials’ attitudes, individual men and women, families, community leaders and structures and social institutions such as churches. Churches are a critical community social institution that could play a pivotal role in addressing GBV. To position churches as players on public issues such as GBV, the questions that emerge are: ‘What is the role of the church in a public problem such as GBV? How could churches conceive and perform a public ministerial role that addresses GBV?’ To respond to these questions, this article employs the idea of public pastoral care as a nexus that churches could utilise in performing a community and public role function in contributing towards addressing GBV. Firstly, the article sketches the context of GBV in Zimbabwe and the various efforts to address it. Secondly, it outlines the ambivalent role of churches in GBV. Thirdly, it conceptualises the notion of public pastoral care as an approach that could be employed by churches to address GBV. Lastly, it proposes some public practical approaches that could be employed in addressing GBV by churches. (shrink)

This article investigates whether implicit racial biases have significant discriminatory effects. To this end, it evaluates meta-analyses of studies on measures of implicit bias and behavioral effects to which they are correlated. On balance, I maintain, the best interpretation of these meta-analyses and relevant surrounding research supports the conclusion that implicit racial biases are significantly correlated to racially biased behaviors, with effects that are consequential at both the individual and group levels. This conclusion is compatible with, but (...) does not entail, the proposition that implicit racial biases in fact cause such effects. In consequence, I consider the contribution implicit bias research might make to our best accounts of racial discrimination and inequality on both a casual and non-causal construal. I argue it is plausible that research on implicit racial bias, on either construal, will play a substantive role in such accounts. (shrink)

In this paper we provide a detailed proof-theoretical analysis of a natural deduction system for classical propositional logic that (i) represents classical proofs in a more natural way than standard Gentzen-style natural deduction, (ii) admits of a simple normalization procedure such that normal proofs enjoy the Weak Subformula Property, (iii) provides the means to prove a Non-contamination Property of normal proofs that is not satisfied by normal proofs in the Gentzen tradition and is useful for applications, especially in formal (...) argumentation, (iv) naturally leads to defining a notion of depth of a proof, to the effect that, for every fixed natural k, normal k-depth deducibility is a tractable problem and converges to classical deducibility as k tends to infinity.

The present study tested the existence of a cognitive schema that guides people's evaluations of the likelihood that observed problem-solving processes will succeed. The hypothesised schema consisted of attributes that were found to distinguish between retrospective case reports of successful and unsuccessful real world problem solving (Lipshitz & Bar Ilan, 1996). Participants were asked to evaluate the likelihood of success of identical cases of problem solving that differed in the presence or absence of diagnosis, the selection of appropriate or inappropriate (...) solutions, and the pairing of diagnosis with appropriate or non-appropriate solutions. Consistent with the proposition, diagnosis affected perceived likelihood of success, albeit only when solution quality was held constant, and appropriate diagnosis with a compatible solution produced higher perceived likelihood of success than appropriate diagnosis with incompatible solutions. In addition, results showed that solution quality played a significant role, and that compatibility with a six-phase rational model of problem solving played no role in judging likelihood of success.

This paper is partly exegetical, partly systematic. I argue that Frege's account of what he called “colouring” contains some important insights on how communication is related to mental states such as mental images or emotions. I also show that the Fregean perspective is supported by current research in psycholinguistics and that a full understanding of some linguistic phenomena that scholars have accounted for in terms of either semantics or pragmatics need involve psycholinguistic elements.

THE mind is the locus of various dispositions, of developed sources and motives of action, which are not mere reflex habits but trained abilities and bents, tendencies, liabilities or inhibitions. Human knowing is more an intending of facts or states of affairs than a relation to them. Knowledge is not a predicamental relation. Consciousness is related to its object not as North Pole to South Pole, nor as container to contained, but as matter to form, and to the physical form (...) of the object of consciousness there corresponds the intentional form of the consciousness itself. To know reality is not to acquire it, grasp it, have it, possess it, contemplate it or dwell in it; it is to be informed by it i.e. intentionally to become it. Knowledge is the form rather than the cause of rational behaviour: technique, method, knack, skill, expertise, know-how, flair, strategic sense, prudence, taste, discretion, caution, judiciousness, decorum, conscientiousness, style, discipline, sagacity, discrimination, wisdom, respect for sense. Such principles operate not by description of nor prescription for, but by incarnation in and information of performance. It is, for instance, man’s respect for sense that is the form of a logically clear expression, and ideas are skills in the use of words. This human capacity and achievement is an intentional becoming, an actuation of the subject, bringing him to act. Yet, properly speaking, it is not action but passion. For knowing is an effect of which reality is the cause, and this causality is not a relation: actio est in passo—not in the agent, nor between the agent and the patient, but in the patient as from the agent, an actuation of the subject in dependence on the object. Of course it may be argued that non datur actio in distans, but far from requiring some intellectual ether, this only means that action and passion are not candidates for the application of spatial or temporal predicates. The known need not be close to the knower. True knowledge is the form of our reason when it is truly about matters of fact. It is not, then, a relation between subject and object, but a knowledge of states of affairs or facts constituted by interrelated objects which, to be known, must comprise some states of affairs of whose constituent objects some, at least, are knowing subjects. Inquiry is related to insight as searching to finding, or as trying to succeeding. Knowing is the second act or actualization of the intellect Thomists regard as second potency, first act, or accidental passive potency. But knowing is not a transitive activity. It is an achievement of intention, not an episode. It is a capacity, disposition, proneness or inclination, in so far as it connotes the abiding possibility of its contents’ polymorphic propositional and non-propositional expression in rational behaviour, which is an effect of knowing as an achievement, though it is also rightly said to be informed by know-how rather than caused by it. The act of self-knowledge consciously intends the self, but the self is intended as known and not as conscious. Thus, though true of consciousness, the distinction between consciously judging and consciously being tickled is not in consciousness but in knowledge of consciousness. Knowledge should be studied not in its products, but in its various expressions, especially in linguistic ones. For words and sentences are the most easily inspected class of things that we think in.

This article studies the cognitive and communicative effects of typographical iconicity in poetry from the perspective of relevance theory. It argues that the visual aspect pertaining to an instance of typographical iconicity conveys a sensory impression, which perceptually resembles elements of the semantic material represented via the typographical iconicity’s lexical aspect. It is suggested that the non-propositional information relating to this impression can trigger the derivation of a wide array of weak implicatures which can combine to form an (...) impressionistic and indeterminate cognitive state described within relevance theory as a poetic effect. Furthermore, since the added effort, which the typographical iconicity requires to be perceived and processed, is offset by the derived implicatures, the use of typographical iconicity may be said to produce an optimally relevant level of processing.

The aim of this paper is to explore the relationship between visual imagery and metaphor, highlighting the historical neglect of this relationship in philosophy and cognitive science and exploring the reasons behind this neglect in theoretical and empirical studies. After outlining influential philosophical theories on the relationship between metaphor and visual imagery, I provide a critical overview of empirical findings on this. Thus, I argue that experimental studies lack sufficient empirical evidence to make meaningful generalizations and fail to determine the (...) true role of visual imagery in metaphor comprehension. Nevertheless, they do not allow us to rule out the involvement of imagery in the comprehension of at least certain metaphors. The present paper proposes that visual imagery might play different roles depending on the semantic features of the vehicle and the kind of meaning conveyed by different types of metaphors. I conclude this discussion by sketching a roadmap for further exploration of this fascinating and challenging relationship. (shrink)

Davidson argues that metaphorical sentences express no propositional contents other than the explicit literal contents they express. He offers a causal account, on the one hand, as an explanation of the supposed additional content of a metaphor in terms of the effects metaphors have on hearers, and on the other hand, as a reason for the non-propositional nature of the “something more” that a metaphor is alleged to mean. Davidson’s account is meant to restrict the semantic notions (...) of meaning, content, and truth, to literal sentences. I argue that the Davidsonian causal account does not satisfactorily account for metaphor’s figurativeness, speakers’ assertion and hearers’ uptake of metaphor, and our discursive practices of using metaphors in disagreements and argumentation. I offer a non-compositional analysis of a semantic account of metaphor within which one can make sense of the applicability of the notions of meaning and content to metaphor. This analysis shows that metaphorical sentences have meanings other than, and in addition to, their literal meanings and what speakers can use them to mean. (shrink)

A wide range of non-pharmaceutical interventions (NPIs) have been introduced to stop or slow down the COVID-19 pandemic. Examples include school closures, environmental cleaning and disinfection, mask mandates, restrictions on freedom of assembly and lockdowns. These NPIs depend on coercion for their effectiveness, either directly or indirectly. A widely held view is that coercive policies need to be publicly justified—justified to each citizen—to be legitimate. Standardly, this is thought to entail that there is a scientific consensus on the factual propositions (...) that are used to support the policies. In this paper, we argue that such a consensus has been lacking on the factual propositions justifying most NPIs. Consequently, they would on the standard view be illegitimate. This is regrettable since there are good reasons for granting the state the legitimate authority to enact NPIs under conditions of uncertainty. The upshot of our argument is that it is impossible to have both the standard interpretation of the permissibility of empirical claims in public justification and an effective pandemic response. We provide an alternative view that allows the state sufficient room for action while precluding the possibility of it acting without empirical support. (shrink)

Epistemic infinitism, advanced in different forms by Peter Klein, Scott Aikin, and David Atkinson and Jeanne Peijnenburg, is the theory that justification of a proposition for a person requires the availability to that person of an infinite, non-repeating chain of propositions, each providing a justifying reason for its successor in the chain. The reductio argument is the argument to the effect that infinitism has the consequence that no one is justified in any proposition, because there will be an infinite chain (...) of reasons supporting any proposition (and similarly, a chain supporting its negation). Four ways of defending infinitism against the reductio argument are considered and found wanting: Peijnenburg and Atkinson’s use of probabilistic chains of reasons; Klein’s concept of emergent justification; Aikin’s insistence that there be non-propositional input in the justification of any proposition; and Klein’s use of the distinction between reasons that are and are not available to a person. I contend that, in the absence of some further defence, the reductio argument makes infinitism untenable. (shrink)

To understand what non-propositional content is and whether there are any such contents, we first need to know what propositional content is. That issue will be the focus of the first section of this essay. In the second section, with an understanding of propositional content in hand, we will consider representations that fail to have propositional content. In contrast to recent literature, it will be argued that metaphysical considerations concerning what's represented, rather than linguistic considerations, are (...) a more promising way of establishing non-propositional contents. To keep the discussion containable, focus will be on representational mental states, though many of the considerations can be extended to other forms of representation. (shrink)

Cognitive-pragmatic approaches to how metaphors are understood view the activation of perceptual or motor effects as inferred. Crucially, inferences elicit conceptual representations, e.g. in the form of implicatures, and/or mental simulations, e.g. in the form of imagery, memory, an impression and other private elements. Emotional effects, being non-conceptual, must be left out of this picture. But evidence in neurolinguistics and psycholinguistics has shown that metaphors activate brain regions linked to emotions, and that in L2, in the absence of (...) fully-propositional meaning, metaphors yield meaningful interpretations by evoking imagery, impressions, emotions. Drawing on relevance-theoretic views, we would like to argue that metaphors are processed in not entirely propositional terms. Subjective experience heuristics allows making rapid responses by absorbing emotions, imagery, impressions, into the interpretation process, an ability which outweighs standard inferential reasoning processes. Such a position is likely to apply to non-metaphorical language, too and thus pervade linguistic processing in general. (shrink)

Michael Dummett has nicely expressed a rather widespread doctrine about the primacy of sentences. He writes: "you cannot DO anything with a word — cannot effect any conventional act by uttering it — save by uttering some sentence containing that word...". In this paper we argue that this doctrine is mistaken: it is not only sentences, but also ordinary words and phrases which can be used in isolation. The argument involves two steps. First: we show — using Sperber and Wilson's (...) relevance theory — that an utterance of "John's father" could COMMUNICATE a proposition. Second: we point out that, in this context, this proposition would be asserted rather than merely implicated. Because there is nothing importantly idiosyncratic about the phrase "John's father", we infer that words and phrases generally can be used in isolation to make assertions. (shrink)

This book explores how our minds represent things in the world, asking whether these representations necessarily have the structure of propositions about the world. The hope is that this will lead towards a more complete understanding of the puzzle of intentionality -- how it is that our minds make contact with the world.

I present a possible worlds semantics for a hyperintensional belief revision operator, which reduces the logical idealization of cognitive agents affecting similar operators in doxastic and epistemic logics, as well as in standard AGM belief revision theory. (Revised) belief states are not closed under classical logical consequence; revising by inconsistent information does not perforce lead to trivialization; and revision can be subject to ‘framing effects’: logically or necessarily equivalent contents can lead to different revisions. Such results are obtained without (...) resorting to non-classical logics, or to non-normal or impossible worlds semantics. The framework combines, instead, a standard semantics for propositional S5 with a simple mereology of contents. (shrink)

It has often been claimed that our believing some proposition is dependent upon our not being committed to a non-epistemic explanation of why we believe that proposition. Very roughly, I cannot believe that p and also accept a non-epistemic explanation of my believing that p. Those who have asserted such a claim have drawn from it a range of implications: doxastic involuntarism, the unacceptability of Humean naturalism, doxastic freedom, restrictions upon the effectiveness of practical (Pascalian) arguments, as well as others. (...) If any of these implications are right, then we would do well to have a precise statement of the nature of this phenomenon central to first-person doxastic explanations, as well as of our reasons for believing that it holds. Both of these are lacking in the literature. This paper is an attempt to elucidate and defend this claim. (shrink)

Book synopsis: Our mental lives are entwined with the world. There are worldly things that we have beliefs about and things in the world we desire to have happen. We find some things fearsome and others likable. The puzzle of intentionality — how it is that our minds make contact with the world — is one of the oldest and most vexed issues facing philosophers. Many contemporary philosophers and cognitive scientists have been attracted to the idea that our minds represent (...) the world. This book explores an important assumption about representation, namely, that when we represent things in the world, we represent them as having properties, and in this way our representations have "propositional" structure. The contributors examine what the commitment to propositionalism amounts to; illuminate why one might find the thesis attractive ; and consider ways in which one might depart from propositionalism. The hope is that this will lead towards a more complete understanding of how the mind and world are connected. (shrink)

Intentionality, or the power of minds to be about, to represent, or to stand for things, remains central in the philosophy of mind. But the study of intentionality in the analytic tradition has been dominated by discussions of propositional attitudes such as belief, desire, and visual perception. There are, however, intentional states that aren't obviously propositional attitudes. For example, Indiana Jones fears snakes, Antony loves Cleopatra, and Jane hates the monster under her bed. The present paper explores such (...) mental states in an introductory but opinionated way. (shrink)

It is often argued that for a perceptual experience to be able to justify perceptual judgments, the perceptual experience must have a propositional content. For, it is claimed, only propositions can bear logical relations such as implication to each other. In this paper, this claim is challenged. It is argued that whereas perceptions and judgments both have intentional content, their contents have different structures. Perceptual content does not have a propositional structure. Perceptions and judgments can nevertheless have the (...) same cognitive significance. So the veridicality of a certain perceptual experience, can imply the truth of certain propositions. Consequently, perceptions can have non-propositional content, but even so justify perceptual judgments which have a propositional structure. (shrink)

Reasoning about change is a central issue in research on human and robot planning. We study an approach to reasoning about action and change in a dynamic logic setting and provide a solution to problems which are related to the Frame problem. Unlike most work on the frame problem the logic described in this paper is monotonic. It (implicitly) allows for the occurrence of actions of multiple agents by introducing non-stationary notions of waiting and test. The need to state a (...) large number of frame axioms is alleviated by introducing a concept of chronological preservation to dynamic logic. As a side effect, this concept permits the encoding of temporal properties in a natural way. We compare the relative merits of our approach and non-monotonic approaches as regards different aspects of the frame problem. Technically, we show that the resulting extended systems of propositional dynamic logic preserve (weak) completeness, finite model property and decidability. (shrink)

I argue first that attention is a (maybe the) paradigmatic case of an object-directed, non-propositional intentional mental episode. In addition attention cannot be reduced to any other (propositional or non-propositional) mental episodes. Yet, second, attention is not a non-propositional mental attitude. It might appear puzzling how one could hold both of these claims. I show how to combine them, and how that combination shows how propositionality and non-propositionality can co-exist in a mental life. The crucial move (...) is one away from an atomistic, building block picture to a more holistic, structural picture. (shrink)

This paper aims to show that modeling complex systems inevitably involves non-propositional knowledge and thus the uncertainties associated with the corresponding model predictions cannot be fully quantified. This is exemplified by means of the climate system and climate modeling. The climate system is considered as a paradigm for a complex system, whereby the notion of complexity adopted in this paper is epistemic in nature and does not equate with the technical definition of a complex system as for example used (...) within physics or complexity theory. The epistemic notion of complexity allows to view the climate system as complex with respect to some features, while simple with respect to others. This distinction is of practical significance for political decision making as it allows to treat some climate predictions as (fairly) certain, while acknowledging high uncertainties with others.

Could there be an implicature whose content is not propositional? Grice's canon is somewhat ambivalent on this question, but such figures as Sperber & Wilson, Davis, and Lepore & Stone presume that there cannot be, and argue that this causes glaring failures within the Gricean programme. Building on work by McDowell and Buchanan, I argue that, on the contrary, the notion of non-propositional implicature is very much worth investigating. I show how the notion has promise to illuminate the (...) content of many sorts of complex utterance—from the cases of verbal irony, metaphorical usage, slurring, insinuation, and (some kinds of) humour, to various others which involve expressive or evaluative content.

W. V. Quine famously defended two theses that have fallen rather dramatically out of fashion. The first is that intensions are “creatures of darkness” that ultimately have no place in respectable philosophical circles, owing primarily to their lack of rigorous identity conditions. However, although he was thoroughly familiar with Carnap’s foundational studies in what would become known as possible world semantics, it likely wouldn’t yet have been apparent to Quine that he was fighting a losing battle against intensions, due in (...) large measure to developments stemming from Carnap’s studies and culminating in the work of Kripke, Hintikka, and Bayart. These developments undermined Quine’s crusade against intensions on two fronts. First, in the context of possible world semantics, intensions could after all be given rigorous identity conditions by defining them (in the simplest case) as functions from worlds to appropriate extensions, a fact exploited to powerful and influential effect in logic and linguistics by the likes of Kaplan, Montague, Lewis, and Cresswell. Second, the rise of possible world semantics fueled a strong resurgence of metaphysics in contemporary analytic philosophy that saw properties and propositions widely, fruitfully, and unabashedly adopted as ontological primitives in their own right. This resurgence — happily, in my view — continues into the present day. -/- For a time, at any rate, Quine experienced somewhat better success with his second thesis: that higher-order logic is, at worst, confused and, at best, a quirky notational alternative to standard first-order logic. However, Quine notwithstanding, a great deal of recent work in formal metaphysics transpires in a higher-order logical framework in which properties and propositions fall into an infinite hierarchy of types of (at least) every finite order. Initially, the most philosophically compelling reason for embracing such a framework since Russell first proposed his simple theory of types was simply that it provides a relatively natural explanation of the paradoxes. However, since the seminal work of Prior there has been a growing trend to consider higher-order logic to be the most philosophically natural framework for metaphysical inquiry, many of the contributors to this volume being among the most important and influential advocates of this view. Indeed, this is now quite arguably the dominant view among formal metaphysicians. -/- In this paper, and against the current tide, I will argue in §1 that there are still good reasons to think that Quine’s second battle is not yet lost and that the correct framework for logic is first-order and type-free — properties and propositions, logically speaking, are just individuals among others in a single domain of quantification — and that it arises naturally out of our most basic logical and semantical intuitions. The data I will draw upon are not new and are well-known to contemporary higher-order metaphysicians. However, I will try to defend my thesis in what I believe is a novel way by suggesting that these basic intuitions ground a reasonable distinction between “pure” logic and non-logical theory, and that Russell-style semantic paradoxes of truth and exemplification arise only when we move beyond the purely logical and, hence, do not of themselves provide any strong objection to a type-free conception of properties and propositions. -/- Most of my arguments in §1 are largely independent of any specific account of the nature of properties and propositions beyond their type-freedom. However, I will in addition argue that there are good reasons to take propositions, at least, to be very fine-grained. My arguments are thus bolstered significantly if it can be shown that there are in fact well-defined examples of logics that are not only type-free but which comport with such a conception of propositions. It is the purpose of §2 to lay out a logic of this sort in some detail, drawing especially upon work by George Bealer and related work of my own. With the logic in place, it will be possible to generalize the line of argument noted above regarding Russell-style paradoxes and, in §3, apply it to two propositional paradoxes — the Prior-Kaplan paradox and the Russell-Myhill paradox — that are often taken to threaten the sort of account developed here.

Traditional normative theories of belief in epistemology presume that belief-forming includes a reflective component and a mental agency component. Beliefs are regarded as conscious doxastic attitudes with propositional contents. Let’s call this view the Transcendental View about Belief (TVB). First, I argue that reputed norms of belief as the truth norm, the knowledge norm and the rationality norm all incorporate TVB. Further, I argue that the empirical evidence concerning belief-forming collected in the last two decades by Rüdiger Seitz, Hans-Ferdinant (...) Angel, Raymond Paloutzian and their colleagues suggests that primal beliefs do not correspond to the description provided by TVB. Primal beliefs are byproducts of perceptive and affective type 1 processing. As such, they are non-propositional multilayer relational states of a cognitive system S that do not presuppose conscious awareness. Thus, I maintain that TVB is normatively inadequate, because it is descriptively false. I presume that a good normative account of beliefs should be able to accommodate primal beliefs and provide a norm of primal belief. I conclude by attempting to outline such a positive account.

As Macnamara (1978) once asked, how can we talk about what we see? We report on a study manipulating realistic dynamic scenes and sentences aiming to understand the interaction between linguistic and visual representations in real-world situations. Specifically, we monitored participants’ eye movements as they watched video clips of everyday scenes while listening to sentences describing these scenes. We manipulated two main variables. The first was the semantic class of the verb in the sentence and the second was the action/motion (...) of the agent in the unfolding event. The sentences employed two verb classes—causatives (e.g., break) and perception/psychological (e.g., notice)—which impose different constraints on the nouns that serve as their grammatical complements. The scenes depicted events in which agents either moved towards a target object (always the referent of the verb-complement noun), away from it, or remained neutral performing a given activity (such as cooking). Scenes and sentences were synchronized such that the verb onset corresponded to the first video frame of the agent motion towards or away from the object. Results show effects of agent motion but weak verb-semantic restrictions: causatives draw more attention to potential referents of their grammatical complements than perception verbs only when the agent moves towards the target object. Crucially, we found no anticipatory verb-driven eye movements toward the target object, contrary to studies using non-naturalistic and static scenes. We propose a model in which linguistic and visual computations in real-world situations occur largely independent of each other during the early moments of perceptual input, but rapidly interact at a central, conceptual system using a common, propositional code. Implications for language use in real world contexts are discussed. (shrink)

We give proofs of the effective monotone interpolation property for the system of modal logic K, and others, and the system IL of intuitionistic propositional logic. Hence we obtain exponential lower bounds on the number of proof-lines in those systems. The main results have been given in [P. Hrubeš, Lower bounds for modal logics, Journal of Symbolic Logic 72 941–958; P. Hrubeš, A lower bound for intuitionistic logic, Annals of Pure and Applied Logic 146 72–90]; here, we give considerably (...) simplified proofs, as well as some generalisations. (shrink)

In a series of articles (Pagin, 2004, 2009), Peter Pagin has argued that assertion is not a social speech act, introducing a method (which we baptize ‘the P-test’) designed to refute any account that defines assertion in terms of its social effects. This paper contends that Pagin's method fails to rebut the thesis that assertion is social. We show that the P-test is both unreliable (because it overgenerates counterexamples) and counterproductive (because it ultimately provides evidence in favor of some (...) social accounts). Nonetheless, we contend that assertion is not fully social. We defend an intermediate view according to which assertion is only a partly social speech act: assertions both commit the speaker to a proposition (a social component) and present their propositional content as true (a non-social component). The upshot is that assertion is in some important respect social, although it cannot be defined solely in terms of its social effects. (shrink)

This paper investigates the question of whether know-how can be regarded as a form of non-propositional intentionality.

Propositionalism is the view that intentional attitudes, such as belief, are relations to propositions. Propositionalists argue that propositionalism follows from the intuitive validity of certain kinds of inferences involving attitude reports. Jubien (2001) argues powerfully against propositions and sketches some interesting positive proposals, based on Russell’s multiple relation theory of judgment, about how to accommodate “propositional phenomena” without appeal to propositions. This paper argues that none of Jubien’s proposals succeeds in accommodating an important range of propositional phenomena, such (...) as the aforementioned validity of attitude-report inferences. It then shows that the notion of a predication act-type, which remains importantly Russellian in spirit, is sufficient to explain the range of propositional phenomena in question, in particular the validity of attitude-report inferences. The paper concludes with a discussion of whether predication act-types are really just propositions by another name. (shrink)

Book synopsis: Our mental lives are entwined with the world. There are worldly things that we have beliefs about and things in the world we desire to have happen. We find some things fearsome and others likable. The puzzle of intentionality — how it is that our minds make contact with the world — is one of the oldest and most vexed issues facing philosophers. Many contemporary philosophers and cognitive scientists have been attracted to the idea that our minds represent (...) the world. This book explores an important assumption about representation, namely, that when we represent things in the world, we represent them as having properties, and in this way our representations have "propositional" structure. The contributors examine what the commitment to propositionalism amounts to; illuminate why one might find the thesis attractive ; and consider ways in which one might depart from propositionalism. The hope is that this will lead towards a more complete understanding of how the mind and world are connected. (shrink)

Peter Anstey rejects the widespread view that all knowledge for Locke is propositional. He argues, instead, that Locke accepts a form of non-propositional knowledge. The perception of the agreement and disagreement of ideas, according to Anstey's interpretation, is akin to what Bertrand Russell called “knowledge by acquaintance.” He presents a careful, four-step analysis of Locke’s view of the acquisition of knowledge, which is designed to show how the mind proceeds from perceiving to affirming, then to assenting, and finally (...) to verbalizing propositions. This comprehensive account takes into account a variety of remarks Locke makes about perception, knowledge and true or false propositions, and Anstey claims that overall this interpretation is a better fit than the orthodox view that Locke held all knowledge to be propositional.

In this study, we are addressing the call for further research (Aikhenvald 2015) into how languages, in our case Modern Greek, mark the unexpected. Our first research question is: Can we identify a class of mirative evidential markers in Modern Greek? The expected answer is that we can, if we take account of frequency rates in a variety of sources in the real world, namely plays, corpora and tags in social media. The second research question is: Do these markers convey (...) propositional or non-propositional meaning? Our findings suggest that the Greek data involves predominantly non-propositional types of meaning since mirativity is not delivered by the semantic content of the utterance (e.g., Ooo! Tí vlépoun ta mátia mou? “Oh! What do I see?”, Ma ti les tóra? “But what are you saying now?”, Ba ba ti akoúo? “Well, well, what do I hear?” Mi mou pis! ‘Don’t tell me!’). (shrink)

Iffication, Preiffication, Qualiffication, Reiffication, and Deiffication. -/- Roughly, iffication is the speech-act in which—by appending a suitable if-clause—the speaker qualifies a previous statement. The clause following if is called the qualiffication. In many cases, the intention is to retract part of the previous statement—called the preiffication. I can retract part of “I will buy three” by appending “if I have money”. This initial study focuses on logical relations among propositional contents of speech-acts—not their full conversational implicatures, which will be (...) treated elsewhere. The modified statement—called the iffication—is never stronger than the preiffication. A degenerate iffication is one logically equivalent to its preiffication. There are limiting cases of degenerate iffications. In one, the qualiffication is tautological, as “I will buy three if three is three”. In another, the negation of the qualiffication implies the preiffication, as “I will buy three if I will not buy three”. Reiffication is iffication of an iffication. “I will buy three if I have money” is reifficated by appending “if there are three left”. Deiffication is the speech-act in which—by appending a suitable and-clause—the effect of an iffication is cancelled so that the result implies the preiffication. “I will buy three if I have money” is deifficated by appending “and I have money”. All further examples come from standard (one-sorted, tenseless, non-modal) first-order arithmetic. All theorems are about first-order arithmetic propositions. An easy theorem, hinted above, is that an iffication is degenerate if and only if the negation of the qualiffication implies the preiffication. The iffication of a conjunction using one of the conjuncts as qualiffication need not imply the other conjunct: “Two is an even square if two is square” does not imply “Two is even”.

It is a widely-held thesis that the content of intentions can be characterized in terms of the truth of a proposition. In this paper I try to reject this idea. First, I argue that, at least for ordinary cases of intention, there cannot be any proposition such that the intention is fulfilled if, and only if, such a proposition is true. After that, I propose an alternative account for the content of intentions. I argue that this content must ultimately involve (...) a particular acting by the agent.IMPACT STATEMENTAn important aspect of my conclusion is that we should revise some widespread assumptions in the current debate between ‘propositionalism' and ‘non-propositionalism'. The ultimate reasons for rejecting conventional forms of the former should also underpin the rejection of the most common understanding of the latter. (shrink)

Argument for fatalism attempts to prove that free choice is a logical or conceptual impossibility. The paper argues that the first two premises of the argument are sound: propositions are either true or false and they have their truth-value eternally. But the claim that from the fatalistic premises with the introduction of some innocent further premise dire consequences follow as regards to the possibility of free choice is false. The introduced premise, which establishes the connection between the first two premises (...) (which are about the nature of propositions) and the concept of free choice is not innocent. It creates the impression that the truth of certain propositions can somehow determine the occurrence of certain events. But no proposition can have such an effect since the counterfactuals If proposition P were true, event E would happen does not say anything about determination. The argument for fatalism is, however, not a boring sophism. It does reveal something about the nature of propositional representation. It shows that each proposition represents necessarily the fact what it represents, i.e. it shows that propositions have their truth conditions non-contingently. But from this nothing follows as regards to the contingent nature of the facts represented. On the bases of the first two premises of the argument for fatalism we cannot infer to the impossibility of free choice. The argument for fatalism should not be interpreted as an attempt to prove on purely logical or conceptual grounds that we do not have the ability to influence future events by our choices. But it could be used to show something about the nature of propositional representation. (shrink)
