This paper argues that various phenomenological considerations support a non-representational causal account of visual experience. This position claims that visual experiences serve as a non-representational causally efficacious medium for the production of beliefs concerning the external world. The arguments are centered on defending a non-representational causal account’s understanding of the cognitive significance of visual experience. Among other things, such an account can easily explain the inextricable role that background beliefs and conceptual capacities play in perceptually-based external world (...) belief-formation processes, the fact that visual mental states constrain beliefs because of their presentational phenomenology, and the phenomenon known as the transparency of visual experience.

The standard opinion is that the force of the constitution hinges on the fact that it is willingly endorsed by the people or, at least representative of the people. This Article challenges this view. More specifically, I differentiate between two types of legitimation: representational legitimation and non-representational or reason-based legitimation. While representational legitimation rests on the fact that the constitution is representative of who the people are or what they want, reason-based constitutions are based on the judgement (...) that the constitution is just or, at least grounded in reason. I also show that some of the puzzles in constitutional theory can be resolved by acknowledging the significance of the latter type of legitimation. For instance, I illustrate that constitutions that were not adopted freely by the nations and could not have been characterized as representative of the people such as the German Constitution can still be legitimate. To put it provocatively: the legitimation of a constitution need not rest on the conviction that it represents the people whom it governs; it may simply rest on the belief that it is a good or just constitution. Representational legitimacy is only one form of legitimacy but not the only one. (shrink)

This paper starts by considering an argument for thinking that predictive processing (PP) is representational. This argument suggests that the Kullback–Leibler (KL)-divergence provides an accessible measure of misrepresentation, and therefore, a measure of representational content in hierarchical Bayesian inference. The paper then argues that while the KL-divergence is a measure of information, it does not establish a sufficient measure of representational content. We argue that this follows from the fact that the KL-divergence is a measure of relative (...) entropy, which can be shown to be the same as covariance (through a set of additional steps). It is well known that facts about covariance do not entail facts about representational content. So there is no reason to think that the KL-divergence is a measure of (mis-)representational content. This paper thus provides an enactive, non-representational account of Bayesian belief optimisation in hierarchical PP. (shrink)

Pure representationalism or intentionalism for phenomenal experience is the theory that all introspectible qualitative aspects of a conscious experience can be analyzed as qualities that the experience non-conceptually represents the world to have. Some philosophers have argued that experiences such as afterimages, phosphenes and double vision are counterexamples to the representationalist theory, claiming that they are non- representational states or have non-representational aspects, and they are better explained in a qualia-theoretical framework. I argue that these states are fully (...) representational states of a certain kind, which I call “automatically non-endorsed representations”, experiential states the veridicality of which we are almost never committed to, and which do not trigger explicit belief or disbelief in the mind of the subject. By investigating descriptive accounts of afterimages by two qualia theorists, I speculate that the mistaken claims of some anti-representationalists might be rooted in confusing two senses of the term “seeming”.

According to the mental continuity claim (MCC), human mental faculties are physical and beneficial to human survival, so they must have evolved gradually from ancestral forms and we should expect to see their precursors across species. Materialism of mind coupled with Darwin’s evolutionary theory leads directly to such claims and even today arguments for animal mental properties are often presented with the MCC as a premise. However, the MCC has been often challenged among contemporary scholars. It is usually argued that (...) only humans use language and that language as such has no precursors in the animal kingdom. Moreover, language is quite often understood as a necessary tool for having representations and forming beliefs. As a consequence, by lacking language animals could not have developed representational systems or beliefs. In response to these worries, we aim to mount a limited defense of the MCC as an empirical hypothesis. First, we will provide a short historical overview of the origins of the MCC and examine some of the motives behind traditional arguments for and against it. Second, we will focus on one particular question, namely whether language as such is necessary for having beliefs. Our goal is to show that there is little reason to think language is necessary for belief. In doing so, we will challenge a view of belief that is widely accepted by those working in animal cognition, namely representational belief, and we will argue that if belief is non-representational, then different research questions and methods are required. We will conclude with an argument that to study the evolution of belief across species, it is essential to begin the study of subjects in their social and ecological environment rather than in contexts that are not ecologically valid along the social and ecological dimensions. Thus, rather than serving as a premise in an argument 3 in favor of animal minds, the MCC can only be defended by empirical investigation, but importantly, empirical investigation of the right sort..

World semantics for relevant logics include so-called non-normal or impossible worlds providing model-theoretic counterexamples to such irrelevant entailments as (A ∧ ¬A) → B, A → (B∨¬B), or A → (B → B). Some well-known views interpret non-normal worlds as information states. If so, they can plausibly model our ability of conceiving or representing logical impossibilities. The phenomenon is explored by combining a formal setting with philosophical discussion. I take Priest’s basic relevant logic N4 and extend it, on the syntactic (...) side, with a representation operator, (R), and on the semantic side, with particularly anarchic non-normal worlds. This combination easily invalidates unwelcome “logical omniscience” in- ferences of standard epistemic logic, such as belief-consistency and closure under entailment. Some open questions are then raised on the best strategies to regiment (R) in order to express more vertebrate kinds of conceivability. (shrink)

Peter Gärdenfors has proved (Philosophical Review, 1986) that the Ramsey rule and the methodologically conservative Preservation principle are incompatible given innocuous-looking background assumptions about belief revision. Gärdenfors gives up the Ramsey rule; I argue for preserving the Ramsey rule and interpret Gärdenfors's theorem as showing that no rational belief-reviser can avoid reasoning nonmonotonically. I argue against the Preservation principle and show that counterexamples to it always involve nonmonotonic reasoning. I then construct a new formal model of belief (...) revision that does accommodate nonmonotonic reasoning. (shrink)

We present a method for relevance sensitive non-monotonic inference from belief sequences which incorporates insights pertaining to prioritized inference and relevance sensitive, inconsistency tolerant belief revision. Our model uses a finite, logically open sequence of propositional formulas as a representation for beliefs and defines a notion of inference from maxiconsistent subsets of formulas guided by two orderings: a temporal sequencing and an ordering based on relevance relations between the putative conclusion and formulas in the sequence. The relevance relations (...) are ternary (using context as a parameter) as opposed to standard binary axiomatizations. The inference operation thus defined easily handles iterated revision by maintaining a revision history, blocks the derivation of inconsistent answers from a possibly inconsistent sequence and maintains the distinction between explicit and implicit beliefs. In doing so, it provides a finitely presented formalism and a plausible model of reasoning for automated agents. (shrink)

It’s common to think that animals think. The cat thinks it is time to be fed, the monkey thinks the dominant is a threat. In order to make sense of what the other animals around us do, we ascribe mental states to them. The cat meows at the door because she wants to be let in. The monkey the monkey fails the test because he doesn’t remember the answer. -/- We explain animal actions in terms of their mental states, just (...) as we do with humans. One of us has argued that our science of animal minds requires that animal behavior be explained in such terms, and this doesn’t lead to a problematic use of folk psychology or anthropomorphism (Andrews 2016, 2020). By “anthropomorphism” we mean the attribution of human psychological, social, or normative properties to non-human animals “usually with the implication it is done without sound justification” (Shettleworth 2010, 477). And by “folk psychology” we mean the commonsense practice of seeing action as caused or accompanied by mental states like belief and desire, emotions, and seeing people in terms of their moods or personality traits, as well as categorizing complex behaviors as examples of grieving, communicating, or teaching (Andrews 2012). Psychologists routinely describe human behaviors in folk psychological terms, so it’s not that the categories are unscientific. The issue with using folk psychology to describe animal behavior is whether observable similarities between human and nonhuman behavior warrants thinking they involve the same psychological kind. The use of folk psychology when talking about animals need not be problematically anthropomorphic, though we need some evidentiary basis for filing animal behavior under some folk psychological category. -/- Despite it being commonplace for humans to attribute thoughts to animals, and there being arguments in favor of doing so in science, the nature of these mental states so many are happy to see in other animals remains unclear. To help bring some focus into the discussion, we will examine the attitude of belief. In this chapter we will examine the various possible statuses of animal beliefs, and the implications of those various views for our folk practice as well as our scientific investigations. (shrink)

This paper presents an effort to induce a Bayesian belief network (BBN) from crime data, namely the national crime victimization survey (NCVS). This BBN defines a joint probability distribution over a set of variables that were employed to record a set of crime incidents, with particular focus on characteristics of the victim. The goals are to generate a BBN to capture how characteristics of crime incidents are related to one another, and to make this information available to domain specialists. (...) The novelty associated with the study reported in this paper lies in the use of a Bayesian network to represent a complex data set to non-experts in a way that facilitates automated analysis. Validation of the BBN’s ability to approximate the joint probability distribution over the set of variables entailed in the NCVS data set is accomplished through a variety of sources including mathematical techniques and human experts for appropriate triangulation. Validation results indicate that the BBN induced from the NCVS data set is a good joint probability model for the set of attributes in the domain, and accordingly can serve as an effective query tool.

This paper combines various structures representing degrees of belief, degrees of disbelief, and degrees of non-belief (degrees of expectations) into a unified whole. The representation uses relations of comparative necessity and possibility, as well as non-probabilistic functions assigning numerical values of necessity and possibility. We define all-encompassing necessity structures which have weak expectations (mere hypotheses, guesses, conjectures, etc.) occupying the lowest ranks and very strong, ineradicable ('a priori') beliefs occupying the highest ranks. Structurally, there are no differences from (...) the top to the bottom. I argue that belief is a vague notion, and that thresholds for belief, if there are any, are context-dependent. (shrink)

I argue for the existence of imaginative beliefs: mental states that are imaginative in format and doxastic in attitude. I advance two arguments for this thesis. First, there are imaginings that play the functional roles of belief. Second, there are imaginings that play the epistemic roles of belief. These arguments supply both descriptive and normative grounds for positing imaginative beliefs. I also argue that this view fares better than alternatives that posit distinct imaginative and doxastic states to account (...) for the same phenomena. Along the way, I demonstrate the theoretical significance of imaginative beliefs by showing how they pose a challenge for standard taxonomies of the mind, clarify the sense in which imagination is occurrent and voluntary, explain the justificatory role of the imagination, and point to a deep but underappreciated symmetry between imagistic and non-imagistic thought.

Decision-theoretic representation theorems have been developed and appealed to in the service of two important philosophical projects: in attempts to characterise credences in terms of preferences, and in arguments for probabilism. Theorems developed within the formal framework that Savage developed have played an especially prominent role here. I argue that the use of these ‘Savagean’ theorems create significant difficulties for both projects, but particularly the latter. The origin of the problem directly relates to the question of whether we can have (...) credences regarding acts currently under consideration and the consequences which depend on those acts; I argue that such credences are possible. Furthermore, I argue that attempts to use Jeffrey’s non-Savagean theorem in the service of these two projects may not fare much better. (shrink)

A sample of Yukatek Maya children was tested on their capacity to attribute false beliefs to a variety of stimuli, both natural and non-natural. Children's capacity to correctly infer that humans have limited perceptual access, and are, therefore, not likely to know what is inside a container if the contents have been surreptitiously replaced, is shown to have significant consequences. Children who passed the test with the human stimulus showed a nuanced capacity to attribute similar or dissimilar knowledge to other (...) natural and non-natural entities, consistently with these entities' cultural representations. In contrast, those who failed the test with the human stimulus tended to attribute similar beliefs to all natural and non-natural entity stimuli. (shrink)

This paper investigates the role of conditionals in hypothetical reasoning and rational decision making. Its main result is a proof of a representation theorem for preferences defined on sets of sentences (and, in particular, conditional sentences), where an agent’s preference for one sentence over another is understood to be a preference for receiving the news conveyed by the former. The theorem shows that a rational preference ordering of conditional sentences determines probability and desirability representations of the agent’s degrees of (...) class='Hi'>belief and desire that satisfy, in the case of non-conditional sentences, the axioms of Jeffrey’s decision theory and, in the case of conditional sentences, Adams’ expression for the probabilities of conditionals. Furthermore, the probability representation is shown to be unique and the desirability representation unique up to positive linear transformation. (shrink)

Abstract In slogan form, the thesis of this paper is that beliefs are self-verifying fictions: We make them up, but in so doing, they come to exist, and so the fiction of belief is in fact true. This picture of belief emerges from a combination of three independently motivated views: (1) a phenomenal intentionalist picture of intentionality, on which phenomenal consciousness is the basis of intentionality; (2) what I will call a “self-ascriptivist” picture of derived representation, on which (...) non-fundamental representational features are a matter of our ascribing contents to ourselves or our mental states or contents; and (3) a representationalist picture of the attitudes, on which the attitude components of mental states (e.g., the “belief” bit of a belief that P) are represented contents. This paper outlines and motivates the view of beliefs as self-verifying fictions, compares the view to alternative views of belief, and contrasts beliefs on the resulting picture to other belief-like mental states.

Explorationism (see www.bu.edu/wcp/Papers/Logi/LogiFaus.htm, WCP XX, “Conflict without Contradiction”) is a perspective concerning human knowledge: as yet, our ignorance of the Real World remains great. With this perspective, all our knowledge is so far only partial and tentative. Evidence Logic (EL) (see “The Concept of Evidence”, INTER. JOURNAL OF INTELLIGENT SYSTEMS 15 (2000), 477‐493) provides an example of a reasonable Base Logic for Explorationism:EL provides machinery for the representation and processing of gradational evidential predications. Syntactically, for any evidence level e, for (...) a proposition symbol P, Pc:e asserts that there is level e confirmatory evidence regarding P, while Pr:e asserts level e refutatory evidence (n‐ary predications, for n>0, are handled similarly). Semantically, EL has similarly enriched model spaces. The Boolean sentence algebras of the variety of EL languages, varying across stipulated families of predicate and functions symbols, have been analyzed, and EL is sound and complete. Belief Systems, we will argue, are all unnecessary: in science, as well as in all broader domains of human relations and activity, it is always sufficient to have simply commitments, which entail no assertion of Truth but rather simply entail agreed‐upon consequent actions. (Agent A believes a sentence S if A asserts S is True although A does not know (have absolute evidence) that S is True.) We will further seek to explore ways in which such a perspective may help in engendering more enhanced discourse, less absolutist and shrill advocacy and violence, and more rationality, in the Global Village of the new century.

Despite the gaining popularity of non-representationalist approaches to cognition, it is still a widespread assumption in contemporary cognitive science that the explanatory reach of representation-eschewing approaches is substantially limited. Nowadays, many working in the field accept that we do not need to invoke internal representations for the explanation of online forms of cognition. However, when it comes to explaining higher, offline forms of cognition, it is widely believed that we must fall back on internal-representation-invoking theories. In this paper, I want (...) to argue that, contrary to popular belief, we don’t yet have any compelling reason for assuming that non-representationalist theories are, as a matter of necessity, limited in scope. I will show that Clark and Toribio’s influential argument in terms of ‘representation-hungry’ cognition is, for various reasons, flawed. On closer inspection, we’ll see that the argument from representation-hunger is, on the one hand, built on an inconsistent notion of representation and, on the other hand, on a conflation of the explanandum with the explanans. I will suggest that, on closer inspection, the ARH seems to be getting its appeal mainly from the unscientific principle that “like causes like”. (shrink)

Research on brain or cognitive/affective processes, culture, social interaction, and structural analysis are overlapping but often independent ways humans have attempted to understand the origins of their evolution, historical, and contemporary development. Each level seeks to employ its own theoretical concepts and methods for depicting human nature and categorizing objects and events in the world, and often relies on different sources of evidence to support theoretical claims. Each level makes reference to different temporal bandwidths (milliseconds, seconds, minutes, hours, days, months, (...) years, decades, and centuries) and focuses on different spatio-temporal activities and controlled and non-controlled stimulus conditions. Biological mechanisms and environmental pressures for survival simultaneously created a gradual intersection and enhancement of cognitive/affective skills, cultural practices, and changes in collaborative social interaction and communicative skills. The evolution of a given level of analysis is assumed to have been incremental and overlapping. These innovative and independent ways humans have learned to characterize their brain or cognitive/affective and social/economic/political life often depend on unexamined, representational re-descriptions or cognitive/affective and socio-cultural devices and forms of communication that facilitate the depiction of practices and beliefs we attribute to respondents or subjects and research colleagues.

Introduction There are some exceptions, which we shall see below, but virtually all theories in psychology and cognitive science make use of the notion of representation. Arguably, folk psychology also traffics in representations, or is at least strongly suggestive of their existence. There are many different types of things discussed in the psychological and philosophical literature that are candidates for representation-hood. First, there are the propositional attitudes – beliefs, judgments, desires, hopes etc. (see Chapters 9 and 17 of this volume). (...) If the propositional attitudes are representations, they are person-level representations – the judgment that the sun is bright pertains to John, not a subpersonal part of John. By contrast, the representations of edges in V1 of the cerebral cortex that neuroscientists talk about and David Marr’s symbolic representations of “zero-crossings” in early vision (Marr 1982) are at the “sub-personal” level – they apply to parts or states of a person (e.g. neural parts or computational states of the visual system). Another important distinction is often made among perceptual, cognitive, and action-oriented representations (e.g. motor commands). Another contrast lies between “stored representations” (e.g. memories) and “active representations” (e.g. a current perceptual state). Related to this is the distinction between “dispositional representations” and “occurrent representations.” Beliefs that are not currently being entertained are dispositional, e.g. your belief that the United States is in North America - no doubt you had this belief two minutes ago, but you were not consciously accessing it until you read this sentence. Occurrent representations, by contrast, are active, conscious thoughts or perceptions. Which leads us to another important distinction: 1 between conscious and non-conscious mental representations, once a bizarre-sounding distinction that has become familiar since Freud (see Chapter 4 of this volume). I mention these distinctions at the outset to give you some idea of the range of phenomena we will be considering, and to set the stage for our central “problem of representation”: what is a mental representation, exactly, and how do we go about deciding whether there are any? We know there are public representations of various kinds: words, maps, and pictures, among others.. (shrink)

On Hume’s account of motivation, beliefs and desires are very different kinds of propositional attitudes. Beliefs are cognitive attitudes, desires emotive ones. An agent’s belief in a proposition captures the weight he or she assigns to this proposition in his or her cognitive representation of the world. An agent’s desire for a proposition captures the degree to which he or she prefers its truth, motivating him or her to act accordingly. Although beliefs and desires are sometimes entangled, they play (...) very different roles in rational agency. In two classic papers (Lewis 1988, 1996), David Lewis discusses several challenges to this Humean picture, but ultimately rejects them. We think that his discussion of a central anti-Humean alternative – the desire-as-belief thesis – is in need of refinnement. On this thesis, the desire for proposition p is given by the belief that p is desirable. Lewis claims that ‘[e]xcept in trivial cases, [this thesis] collapses into contradiction’(Lewis 1996, p. 308). The problem, he argues, is that the thesis is inconsistent with the purportedly plausible requirement that one’s desire for a proposition should not change upon learning that the proposition is true; call this the invariance requirement. In this paper, we revisit Lewis’s argument. We show that, if one carefully distinguishes between non-evaluative and evaluative propositions, the desire-asbelief thesis can be rendered consistent with the invariance requirement. Lewis’s conclusion holds only under certain conditions: the desire-as-belief thesis conflicts with the invariance requirement if and only if there are certain correlations between non-evaluative and evaluative propositions. But when there are such correlations, we suggest, the invariance requirement loses its plausibility. Thus Lewis’s argument against the desire-as-belief thesis appears to be valid only in cases in which it is unsound. (shrink)

This thesis proposes and presents two new models for belief representation and belief revision. The first model is the B-structures model which relies on a notion of partial language splitting and tolerates some amount of inconsistency while retaining classical logic. The model preserves an agent's ability to answer queries in a coherent way using Belnap's four-valued logic. Axioms analogous to the AGM axioms hold for this new model. The distinction between implicit and explicit beliefs is represented and psychologically (...) plausible, computationally tractable procedures for query answering and belief base revision are obtained. ;The second model presents a method for relevance sensitive non-monotonic inference from belief sequences which incorporates insights pertaining to prioritized inference and relevance sensitive, inconsistency tolerant belief revision. Our model uses a finite, logically open sequence of propositional formulas as a representation for beliefs and defines a notion of inference from maxiconsistent subsets of formulas guided by two orderings: a temporal sequencing and an ordering based on relevance relations between the conclusion and formulas in the sequence. The relevance relations are ternary as opposed to standard binary axiomatizations. The inference operation thus defined easily handles iterated revision by maintaining a revision history, blocks the derivation of inconsistent answers from a possibly inconsistent sequence and maintains the distinction between explicit and implicit beliefs. In doing so, it provides a finitely representable formalism and a plausible model of reasoning for automated agents. (shrink)

Two systems of belief change based on paraconsistent logics are introduced in this article by means of AGM-like postulates. The first one, AGMp, is defined over any paraconsistent logic which extends classical logic such that the law of excluded middle holds w.r.t. the paraconsistent negation. The second one, AGMo , is specifically designed for paraconsistent logics known as Logics of Formal Inconsistency (LFIs), which have a formal consistency operator that allows to recover all the classical inferences. Besides the three (...) usual operations over belief sets, namely expansion, contraction and revision (which is obtained from contraction by the Levi identity), the underlying paraconsistent logic allows us to define additional operations involving (non-explosive) contradictions. Thus, it is defined external revision (which is obtained from contraction by the reverse Levi identity), consolidation and semi-revision, all of them over belief sets. It is worth noting that the latter operations, introduced by S. Hansson, involve the temporary acceptance of contradictory beliefs, and so they were originally defined only for belief bases. Unlike to previous proposals in the literature, only defined for specific paraconsistent logics, the present approach can be applied to a general class of paraconsistent logics which are supraclassical, thus preserving the spirit of AGM. Moreover, representation theorems w.r.t. constructions based on selection functions are obtained for all the operations. (shrink)

Book synopsis: The aim of this collection of papers is to present different philosophical perspectives on the mental, exploring questions about how to define, explain and understand the various kinds of mental acts and processes, and exhibiting, in particular, the contrast between naturalistic and non-naturalistic approaches. There is a long tradition in philosophy of clarifying concepts such as those of thinking, knowing and believing. The task of clarifying these concepts has become ever more important with the major developments that have (...) taken place over the last century in the human and cognitive sciences - most notably, psychology, sociology, linguistics, neurophysiology, AI, and cognitive science itself. In all these sciences, there is a need to delineate the domain of the mental and to elucidate the key concepts and underlying assumptions. This need is widely recognized, but approaches and answers vary significantly. Some stress the representational features involved in most of our mental processes, others the inferential dimension; some stress the necessity of using empirical data, others the need to refine ideas before pursuing and drawing on empirical research. The papers collected in this volume are grouped into four parts, on language and thought, on knowledge, belief and action, on intentionality, and on naturalism. The volume will be welcomed by all those engaged and interested in debates about the mental in philosophy and the human and cognitive sciences. (shrink)

A full account of purposive action must appeal not only to propositional attitude states like beliefs, desires, and intentions, but also to motor representations, i.e., non-propositional states that are thought to represent, among other things, action outcomes as well as detailed kinematic features of bodily movements. This raises the puzzle of how it is that these two distinct types of state successfully coordinate. We examine this so-called “Interface Problem”. First, we clarify and expand on the nature and role of motor (...) representations in explaining intentional action. Next, we characterize the respective functions of intentions and motor representations, the differences in representational format and content that these imply, and the interface challenge these differences in turn raise. We then evaluate Butterfill and Sinigaglia’s recent answer to this interface challenge, according to which intentions refer to action outcomes by way of demonstrative deference to motor representations. We present some worries for this proposal, arguing that, among other things, it implicitly presupposes a solution to the problem, and so cannot help to resolve it. Finally, we suggest that we may make some progress on this puzzle by positing a “content-preserving causal process” taking place between intentions and motor representations, and we offer a proposal for how this might work.

For non-additive set functions, the independent product, in general, is not unique and the Fubini theorem is restricted to slice-comonotonic functions. In this paper, we use the representation theorem of Gilboa and Schmeidler (Math Oper Res 20:197–212, 1995) to extend the Möbius product for non-additive set functions to non-finite spaces. We extend the uniqueness result of Ghirardato (J Econ Theory 73:261–291, 1997) for products of two belief functions and weaken the requirements on the marginals necessary to obtain the Fubini (...) property in the product. More importantly, we show that for the Möbius product one side of the Fubini theorem holds for all integrable functions if one of the marginals either is a probability or a convex combination of a chain of unanimity games, i.e., we relax the requirement of slice-comonotonicity and enrich the set of possible applications.

Logic has been a—disputed—ingredient in the emergence and development of the now very large field known as knowledge representation and reasoning. In this book (in progress), I select some central topics in this highly fruitful, albeit controversial, association (e.g., non-monotonic reasoning, implicit belief, logical omniscience, closed world assumption), identifying their sources and analyzing/explaining their elaboration in highly influential published work.

In this paper I want to hold, first, that one may suitably reconstruct the relevant kind of mental representational states that fiction typically involves, make-beliefs, as contextually unreal beliefs that, outside fiction, are either matched or non-matched by contextually real beliefs. Yet moreover, I want to claim that the kind of make-believe that may yield the mark of fictionality is not Kendall Walton’s invitation or prescription to imagine. Indeed, in order to appeal in terms of make-believe to a specific (...) form of imagination that fiction distinctively involves, one must move away from the realm of norms in order to attain a cognitive realm; namely, one must look at a specific form of metarepresentational state. This metarepresentational state of make-believe is a second-order representation that is about both real beliefs and make-beliefs, as the first-order representations it compares by acknowledging their contextual distinctness.

Human beings seem to capture time and the temporal properties of events and things in thought by having beliefs usually expressed with statements using tense, or notions such as ‘now’, ‘past’ or ‘future’. Tensed beliefs like these seem indispensable for correct reasoning and timely action. For instance, my belief that my root canal is over seems inexpressible with a statement that does not use tense or a temporal indexical. However, the dominant view on the nature of time is that (...) it forms, with space, a four-dimensional continuum where time does not encompass private perspectives or an absolute, fixed present. This ‘tenseless’ theory of time encounters a challenge in integrating tensed belief, because it cannot easily explain what constitutes a tensed belief in a tenseless world and how such a belief works inside our cognitive network to bring about the actions it does. Providing such an account is the main goal of this dissertation. -/- I argue here that the correct way to proceed would be to utilize philosophical theories dealing with indexicality, as the puzzling features of tensed belief are shared with beliefs expressed by first-person or spatial indexicals. In chapters II and III I expand the dominant theories about indexicality (Lewis, Perry, Kaplan) and apply them to tensed belief. I show that each is in certain respects incomplete or inadequate. -/- My preferred account critiques the preceding theories as mis-attributing the indexicality involved to a fully conceptual element in the way people think about time. I argue that we should instead connect tensed belief to not fully conceptual elements thought. For support I turn to work in perceptual psychology that connects beliefs about space to perceptions of spatial features. In chapter IV I develop an analogous argument about temporal thought and discuss how mental representations involved in perceptions are constitutively related to the formation and preservation of tensed beliefs. Combining this story with a tenseless theory of time should give us a complete, metaphysically uncontroversial, account of the way a tensed belief functions in reasoning and produces timely action.

Many cognitive accounts of emotional processing assume that emotions have representational content that can be influenced by beliefs and desires. It is generally thought that emotions also have non-cognitive, affective components, including valence and arousal. To clarify the impact of cognition on these affective components we asked participants to rate sentences along cognitive and affective dimensions. For the former case, participants rated the believability of the material. For the latter case, they provided valence and arousal ratings. Across two experiments, (...) we show that valence and arousal are differently influenced by beliefs, suggesting that these two largely independent affective components of emotion differ in their cognitive penetrability. While both components depended upon overall comprehension of sentence meaning, only valence was influenced by the consistency of the sentences with participants’ beliefs (i.e., whether it was believable or unbelievable). We discuss the implications of these findings for understanding cognition–emotion relationships. (shrink)

Abduction was first introduced in the epistemological context of scientific discovery. It was more recently analyzed in artificial intelligence, especially with respect to diagnosis analysis or ordinary reasoning. These two fields share a common view of abduction as a general process of hypotheses formation. More precisely, abduction is conceived as a kind of reverse explanation where a hypothesis H can be abduced from events E if H is a good explanation of E. The paper surveys four known schemes for abduction (...) that can be used in both fields. Its first contribution is a taxonomy of these schemes according to a common semantic framework based on belief revision. Its second contribution is to produce, for each non-trivial scheme, a representation theorem linking its semantic framework to a set of postulates. Its third contribution is to present semantic and axiomatic arguments in favor of one of these schemes, ordered abduction, which has never been vindicated in the literature. (shrink)

In his superb book, The Metaphysics of Representation, Williams sketches biconditional reductive definitions of representational states in non-representational terms. The central idea is an extremely innovative variety of interpretationism about belief and desire. Williams is inspired by David Lewis but departs significantly from him. I am sympathetic to interpretationism for some basic beliefs and desires. However, I will raise three worries for Williams’s version (§2–4). It neglects the role of conscious experience, it makes beliefs and desire too (...) dependent on "hidden facts", and it commits to the unmotivated and problematic claim that mental content is always explanatorily prior to linguistic content. Then, I will suggest a modified version of interpretationism that avoids these problems (§5). I will conclude with a general question (§6). -/- . (shrink)

1. IntroductionIn this superb book, Williams sets a very ambitious goal for himself: to sketch biconditionals that define representational conditions in non-representational terms (p. xvii). Representation is not a spooky, primitive capacity of the mind; it is built from more basic ingredients. At the centre is his radical interpretation theory of belief and desire, inspired by the work of David Lewis. To a first approximation: Basic radical interpretation theory. The correct assignment of beliefs and desires to an (...) agent is the most rationalizing assignment given her perceptual evidence and dispositions to act. (pp. 16, 97ff)Williams does not give a master argument for this account of belief and desire over rival accounts in which constitutive rationality plays no role. Rather, his main goal is the laudatory one of theory-building. In this respect, his book hearkens back to the decade or so from the early 80s to the early 90s that was the heyday for developing grand theories of representation. In particular, his main aim is to develop the details of the basic radical interpretation theory – something Lewis never fully did. The result is a unique, multi-stage theory of representation that departs importantly from Lewis in many places. (shrink)

Patients with mental illness, and depression in particular, present clinicians and surrogate decision-makers with complex ethical dilemmas when they refuse life-sustaining non-psychiatric treatment. When treatment rejection is at variance with the beliefs and preferences that could be expected based on their premorbid or “authentic” self, their capacity to make these decisions may be called into question. If capacity cannot be demonstrated, medical decisions fall to surrogates who are usually advised to decide based on a substituted judgment standard or, when that (...) is not possible, best interest. We propose that in cases where the patient meets the widely accepted cognitive criteria for capacity but is making decisions that appear inauthentic, the surrogate may best uphold patient autonomy by following a “restorative representation” model. We see restorative representation as a subset of substituted judgement in which the decision-maker retains responsibility for deciding as the patient would have, but discerns the decision their “truest self” would make, rather than inferring their current wishes, which are directly influenced by illness. Here we present a case in which the patient’s treatment refusal and previously undiagnosed depression led to difficulty determining the patient’s authentic wishes and placed a distressing burden on the surrogate decision-maker. We use this case to examine how clinicians and ethicists might better advise surrogates who find themselves making these clinically and emotionally challenging decisions. (shrink)

The development of collective beliefs via informational and reputational cascades represents a way of shortcircuiting the difficulties related to the collective action of ‘latent groups’ to ensure the promotion of their particular interests. This essay focuses on the protection of consumers, whose quality of the life has never been so high, despite the prevalence of hazardous products.Rationally ignorant individuals form their opinions by conforming to those of others; this can take two forms, either by consolidating their personal judgement or their (...) private information, or by pure conformist behaviour. It may even be that such individuals rarely hesitate, if necessary, to admit beliefs that they do not actually hold in order to avoid being ostracised by others. ‘Latent groups’ activists manipulate the process of formation of beliefs in order to bring about a predominant opinion on any given issue. Armed with the asset of the prevailing opinion, pressure can be exerted upon politicians in view of obtaining regulations and subsidies which would protect the ‘latent group’ of which they claim to be the representatives.This is the new face of collective action where the “politically correct” replaces physical violence or the strike. This way of shaping public opinion could have a beneficial outcome if it were not founded on erroneous information or led to a violation of individual rights due to regulation. However, this not the case. The very leitmotif of this method is, in fact, to bring about regulation which, by definition, violates private lives. In any case, it is dangerous because the manipulation of public opinion by these activists implies an intensive use of rhetoric, distorting the perception of risk, which in turn involves the circulation of misleading information in order to create a cascade modifying public opinion in favor of the proposed regulation, rather than informing the public on the potential risks and letting them insure freely against it if they judge to do so. But for the activist the end justifies the means. Thus, this manipulation of public opinion is a danger to the notion of modern democracy, already so sensitive to the pertaining to the majority.La formation des croyances par le biais des cascades d’information et de réputation est un moyen de courtcircuiter les difficultés liées à l’action collective des groupes latents pour assurer la promotion de leurs intérêts particuliers. Dans le cadre de cet essai est analysée la protection des consommateurs, dont la valeur de la vie est élevée, contre les produits à risque.Les individus rationnellement ignorants forment leurs opinions en se conformant aux croyances des autres, soit pour conforter leur jugement personnel ou leurs informations privées, soit par conformisme pur. Il se peut même que les individus n’hésitent pas, s’il le faut, à afficher de fausses croyances, pour ne pas être frappés d’ostracisme par les autres.Les activistes des “groupes latents” manipulent le processus de formation des croyances pour faire émerger une opinion majoritaire sur un problème spécifique. Grâce à cette opinion majoritaire ils vont pouvoir faire pression auprès des hommes politiques pour obtenir une réglementation et des subventions à leur propre profit dans le but de protéger le “groupe latent” dont ils prétendent être les représentants. Ce sont les nouvelles formes d’action collective où le politiquement correct remplace la violence physique ou le piquet de grève.Cette façon de former l’opinion publique pourrait avoir des conséquences bénéfiques si elle n’était pas fondée sur des informations erronées et si elle n’aboutissait pas à une violation des droits individuels par la réglementation. Or ce n’est pas le cas. Elle est faite justement pour faire émerger une réglementation qui par définition viole la vie privée des gens. Par ailleurs, elle est dangereuse parce que la manipulation de l’opinion publique par ces activistes implique un usage intensif de figures de rhétorique, de biais dans la perception des risques, de diffusion de fausses informations dans le but d’enclencher une cascade qui va modifier l’opinion publique en faveur de la réglementation et non pas dans le but d’éclairer le public sur les véritables risques encourus, la fin justifiant les moyens.Cette manipulation des croyances est alors un danger pour la démocratie politique contemporaine déjà si sensible à l’opinion majoritaire.

We introduce a new operator, called rational evaluation, in belief change. The operator evaluates new information according to the agent’s core beliefs, and then exports the plausible part of the new information. It belongs to the decision module in belief change. We characterize rational evaluation by axiomatic postulates and propose two functional constructions for it, based on the well-known constructions of kernel sets and remainder sets, respectively. The main results of the paper are two representation theorems with respect (...) to the two functional constructions. We also compare and connect the evaluation operator with some related operators in belief revision, including contraction, set contraction, and prioritized multiple revision. (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)

In this paper, the philosophy of mystical experience, assuming that the mystical experience of intelligibility, and its compatibility with the philosophy. In the previous issue, the article explores mystical experience is compatible with the appearance, mystical experience is a purely silent or have conversations, and the body in the position of mystical experience in three issues. In this regard, this analysis shows, first, to beyond the mystical experience, although the appearance and body together眞real, but does not exclude the appearance, on (...) the contrary, the symbolic representation of the mystical experience can come prepared, but also in mystical experience be after the performance; second, nor blindly mystical silence, no conversation. Instead, starting from the mystical experience to talk, peaked in conversation, and will ultimately be returned to talk; Finally, mystical experience is no need to reject the body, but there should not be assumed on the psychosomatic theory of binary, the ethical claims to wishes to keep justice, on the contrary in theology, "Incarnation," the truth. Negative, way beyond the body only has significance, just as sure to return the body also has a methodology and positive meaning. This analysis not only mystical experience and the broad role of rational consistency, but also coincide with the everyday life experiences. In other words, mystical experience can also serve as one form of human self-understanding, not only can not irrational or contrary to the confusing world of daily life, and humanity should be to deepen and expand its purpose. This article would like to proceed from the assumption that mystical experience has a rational basis and is compatible with philosophy. From this premise, this article would like to discuss whether or not mystical experience and representatiion are compatible, whether mystical experience is purely incommunicable or can there be dialogue and what is the status of the body in mystical experience. Firstly, this article would like to reveal that even though mystical experience transcends representation, it does not exclude representation. On the contrary, symbolic representation prepares the approach to mystical experience and can enhance representation after such experience. Secondly, mystical experience is not altogether incommunicable, devoid of any possible dialogue. On the contrary, mystical experience starts with dialogue and culminates in dialogues until it can finally turn into dialogues on a more mundane level. Finally, mystical experience does not entirely disregard the body and posit an ontological mind-body duality. In theology, it is the notion of "Truth complete in Flesh", an ethical belief that man has, desiring to be part of heaven. The renunciation and the transcending of the body have meaning only as instrument just as the returning to the body has positive value only on a methodological basis. This sort of analysis not only shows that mysticism can be rational in the broadest sense of the word, but that it is also in conformity to everyday existence. In other words, mysticism is not exclusively a non-rational mechanism employed to lead people into confusion, it should aim at the deepening of human development, thus helping people to achieve their ultimate goals.

In recent years, sequencing technologies have enabled the identification of a wide range of non-coding RNAs (ncRNAs). Unfortunately, annotation and integration of ncRNA data has lagged behind their identification. Given the large quantity of information being obtained in this area, there emerges an urgent need to integrate what is being discovered by a broad range of relevant communities. To this end, the Non-Coding RNA Ontology (NCRO) is being developed to provide a systematically structured and precisely defined controlled vocabulary for the (...) domain of ncRNAs, thereby facilitating the discovery, curation, analysis, exchange, and reasoning of data about structures of ncRNAs, their molecular and cellular functions, and their impacts upon phenotypes. The goal of NCRO is to serve as a common resource for annotations of diverse research in a way that will significantly enhance integrative and comparative analysis of the myriad resources currently housed in disparate sources. It is our belief that the NCRO ontology can perform an important role in the comprehensive unification of ncRNA biology and, indeed, fill a critical gap in both the Open Biological and Biomedical Ontologies (OBO) Library and the National Center for Biomedical Ontology (NCBO) BioPortal. Our initial focus is on the ontological representation of small regulatory ncRNAs, which we see as the first step in providing a resource for the annotation of data about all forms of ncRNAs. The NCRO ontology is free and open to all users. (shrink)

As van Fraassen pointed out in his opening remarks, Henry Kyburg's lottery paradox has long been known to raise difficulties in attempts to represent full belief as a probability greater than or equal to p, where p is some number less than 1. Recently, Patrick Maher has pointed out that to identify full belief with probability equal to 1 presents similar difficulties. In his paper, van Fraassen investigates ways of representing full belief by personal probability which avoid (...) the difficulties raised by Maher's measure-theoretic version of the lottery paradox. Van Fraassen's more subtle representation dissolves the simple identification of full belief with maximal personal probability. His investigation exploits the richer resources for representing opinion provided by taking conditional, rather than unconditional, personal probability as fundamental. It has interesting implications for equivalent alternative approaches based on non-Archimedean probability, as well as for equivalent approaches in which assumption contexts representing full belief relative to suppositions are taken as fundamental.

In this study, we examine the problem of belief revision, defined as deciding whic h of several initially-accepted sentences to disbelieve, when new information presents a l ogical inconsistency with the initial set. In the first three experiments, the initial sentence set included a conditional sentence, a non-conditional sentence, and an inferred conclusi on drawn from the first two. The new information contradicted the inferred conclusion. Results indicated that the conditional sentences were more readily abandoned than non-c onditional sentences, (...) even when either choice would lead to a consistent belief state, and that this preference was more pronounced when problems used natural language cover sto ries rather than symbols. The pattern of belief revision choices differed depending on whe ther the contradicted conclusion from the initial belief set had been a modus ponens or m odus tollens inference. Two additional experiments examined alternative model-theoretic definitions of minimal change to a belief state, using problems that contained multiple mo dels of the initial belief state and of the new information that provided the contradiction. The results indicated that people did not follow any of four formal definitions of minimal change on these problems. The new information and the contradiction it offered was not, for example, used to select a particular model of the initial belief state as a way of reconci ling the contradiction. The preferred revision was to retain only those initial sentences th at had the same, unambiguous truth value within and across both the initial and new info rmation sets. The study and results are presented in the context of certain logic-based for malizations of belief revision, syntactic and model-theoretic representations of belief stat es, and performance models of human deduction. Principles by which some types of sent ences might be more "entrenched" than others in the face of contradiction are also discuss ed from the perspective of induction and theory revision. (shrink)

In this paper, by suggesting a formal representation of science based on recent advances in logic-based Artificial Intelligence (AI), we show how three serious concerns around the realisation of traditional scientific realism (the theory/observation distinction, over-determination of theories by data, and theory revision) can be overcome such that traditional realism is given a new guise as ‘naturalised’. We contend that such issues can be dealt with (in the context of scientific realism) by developing a formal representation of science based on (...) the application of the following tools from Knowledge Representation: the family of Description Logics, an enrichment of classical logics via defeasible statements, and an application of the preferential interpretation of the approach to Belief Revision.

This paper presents results of the author’s PhD research: Catholic beliefs and practices, attitudes toward marriage, life and sexuality. The empirical support is a survey made to a sample of 500 students from Lisbon public universities, using a non-random sampling in two phases, first a quota sampling and after a convenience one. There are some results that stand out. More than half of students of the sample call themselves Catholic and believe in the dogmatic representations about God, Jesus and Mary, (...) though other dogmatic beliefs as hell, purgatory and resurrection are much lower. There is some spirituality among students, although the importance of God is less important. The frequencies of the Mass, prayer, Holy Communion, confession are all very low. The attitudes toward marriage, life and sexuality lie between ‘some’ and ‘very’, with abortion having the smallest rating and contraception the highest. In general, undergraduate youth is away from the norms of the Church. At the same time, these youngsters believe and belong more than they practice. Keywords: Beliefs. Practices. Attitudes. Portugal. Undergraduate students. Resumo Este artigo apresenta resultados da tese de doutoramento do autor: crenças e práticas católicas, atitudes em relação ao casamento, à vida e à sexualidade. O suporte empírico é um inquérito aplicado a uma amostra de 500 estudantes das universidades públicas de Lisboa, usando uma amostragem não aleatória em duas fases, primeiro a amostragem por quotas e depois a amostragem por conveniência. Há alguns resultados que se destacam. Mais do que metade da amostra denomina-se católica e acredita nas representações dogmáticas de Deus, Jesus e Maria, embora outras crenças dogmáticas como inferno, purgatório e ressurreição sejam bastante mais baixas. Há alguma espiritualidade entre os estudantes, embora menos considerem que Deus seja importante. A frequência da Missa, oração, comunhão, confissão é muito baixa. As atitudes relativamente ao casamento, vida e sexualidade estão entre ‘alguma’ e ‘muita’, tendo o aborto o valor mais pequeno e a contracepção o valor maior. Na generalidade, a juventude universitária está afastada das normas da Igreja. Ao mesmo tempo, eles acreditam e pertencem mais do que praticam. Palavras-chave: Crenças. Práticas. Atitudes. Portugal.

In this article, Savage’s theory of decision-making under uncertainty is extended from a classical environment into a non-classical one. The Boolean lattice of events is replaced by an arbitrary ortho-complemented poset. We formulate the corresponding axioms and provide representation theorems for qualitative measures and expected utility. Then, we discuss the issue of beliefs updating and investigate a transition probability model. An application to a simple game context is proposed.

This paper starts from the fact that the study of narrative in contemporary Anglo-American philosophy is almost exclusively the study of fictional narrative. It returns to an earlier debate in which Hayden White argued that “historiography is a form of fiction-making.” Although White’s claims are hyperbolical, the paper argues that he was correct to stress the importance of the claim that fiction and non-fiction use “the same techniques and strategies.” A distinction is drawn between properties of narratives that are simply (...) properties of narratives and properties of narratives that play a role in forming readers’ beliefs about the world. Using this distinction, it is shown that it is an important feature of non-fictions that they are narratives; it is salutary to recognise non-fictions as being more like fictions than they are like the events they represent.

In this essay I argue that in order to secure some of his system’s key commitments, Fichte employs argumentation essentially patterned after the technique of practical postulation in Kant. This is a mode of reasoning that mobilizes a distinctly Kantian notion of nonepistemic justification, which itself is premised upon a broadly Kantian conception of the nature of reason. Succinctly stated, such argumentation proceeds essentially as follows. (1) By the basic nature and operations of rationality, every rational being is, as such, (...) committed to E as an ultimate end (final purpose, highest goal). (2) E can be understood as actually attainable only if descriptive proposition P is assented to. (3) We cannot, in principle, possess genuine evidence for or against P; therefore, (4) while we do not have (and never could have) good epistemic grounds for assenting to P, we do have (and always will have) perfectly sufficient rational grounds for doing so. While this assent has no basis in pertinent evidence, it nonetheless has an unshakeable foundation in the basic operations and requirements of rationality. This is so because this assent (a) sustains a commitment integral to rationality as such, and (b) affirms a proposition that no evidence could ever discredit. I proceed to discuss what I take to be two instances of this sort of argumentation in Fichte: first, The Vocation of Man's unusual argument for belief in the real existence of a world transcendent to human representations, and second, the same work's subsequent depiction of that world as strictly mentalistic (immaterial, intellectual, teleological) in its true constitution. VM portrays both positions as decisive determinants of the overall upshot of the Wissenschaftslehre (WL), and explicitly casts them as articles of “faith” or “belief” (Glaube), grounded in unshakeable ethical conviction, by contrast with items of “knowledge” (Wissen).
