Physical theories often characterize their observables with real number precision. Many non-fundamental theories do so needlessly: they are more precise than they need to be to capture the physical matters of fact about their observables. A natural expectation is that a truly fundamental theory will require its full precision in order to exhaustively capture all of the fundamental physical matters of fact. I argue against this expectation and I show that we do not have good reason to expect that the (...) standard of precision set by successful theories, or even by a truly fundamental theory, will match the granularity of the physical facts.

In a recent paper, Yoaav Isaacs, Alan Hájek, and John Hawthorne argue for the rational permissibility of "credal imprecision" by appealing to certain propositions associated with non-measurable spatial regions: for example, the proposition that the pointer of a spinner will come to rest within a certain non-measurable set of points on its circumference. This paper rebuts their argument by showing that its premises lead to implausible consequences in cases where one is trying to learn, by making multiple observations, whether (...) a certain outcome is associated with a non-measurable region or a measurable one.

This article provides an experimental analysis of attitude toward imprecise and variable information. Imprecise information is provided in the form of a set of possible probability values, such that it is virtually impossible for the subjects to guess or estimate, which one in the set is true or more likely to be true. We investigate how geometric features of such information pieces affect choices. We find that the subjects care about more features than the pairs of best-case and (...) worst-case, which is a counter-evidence to the well-known models, maximin and α-maximin. We find that presence of nonextreme points in the set affects choice, which suggests that attitude toward imprecision is ‘nonlinear.’ We also obtain an observation, though not significant, that information pieces have a complementarity that may not be explained by the Bayesian view.

We propose a method for estimating subjective beliefs, viewed as a subjective probability distribution. The key insight is to characterize beliefs as a parameter to be estimated from observed choices in a well-defined experimental task and to estimate that parameter as a random coefficient. The experimental task consists of a series of standard lottery choices in which the subject is assumed to use conventional risk attitudes to select one lottery or the other and then a series of betting choices in (...) which the subject is presented with a range of bookies offering odds on the outcome of some event that the subject has a belief over. Knowledge of the risk attitudes of subjects conditions the inferences about subjective beliefs. Maximum simulated likelihood methods are used to estimate a structural model in which subjects employ subjective beliefs to make bets. We present evidence that some subjective probabilities are indeed best characterized as probability distributions with non-zero variance. (shrink)

An imprecise measurement of a dynamical variable (such as a spin component) does not, in general, give the value of another dynamical variable (such as a spin component along a slightly different direction). The result of the measurement cannot be interpreted as the value of any observable that has a classical analogue.

This article presents the results of a survey designed to test, with economically sophisticated participants, Ellsberg’s ambiguity aversion hypothesis, and Smithson’s conflict aversion hypothesis. Based on an original sample of 78 professional actuaries (all members of the French Institute of Actuaries), this article provides empirical evidence that ambiguity (i.e. uncertainty about the probability) affect insurers’ decision on pricing insurance. It first reveals that premiums are significantly higher for risks when there is ambiguity regarding the probability of the loss. Second, it (...) shows that insurers are sensitive to sources of ambiguity. The participants indeed, charged a higher premium when ambiguity came from conflict and disagreement regarding the probability of the loss than when ambiguity came from imprecision (imprecise forecast about the probability of the loss). This research thus documents the presence of both ambiguity aversion and conflict aversion in the field of insurance, and discuses economic and psychological rationales for the observed behaviours.

Several arguments are considered which purport to demonstrate the impossibility of theory-neutral observation. The most important of these infers the continuity of observation with theory from the presumed continuity of perception with cognition, a doctrine widely espoused in recent cognitive psychology. An alternative psychological account of the relation between cognition and perception is proposed and its epistemological consequences for the observation/theory distinction are then explored.

This paper presents a formalism that combines useful properties of both logic and probabilities. Like logic, the formalism admits qualitative sentences and provides symbolic machinery for deriving deductively closed beliefs and, like probability, it permits us to express if-then rules with different levels of firmness and to retract beliefs in response to changing observations. Rules are interpreted as order-of-magnitude approximations of conditional probabilities which impose constraints over the rankings of worlds. Inferences are supported by a unique priority ordering on (...) rules which is syntactically derived from the knowledge base. This ordering accounts for rule interactions, respects specificity considerations and facilitates the construction of coherent states of beliefs. Practical algorithms are developed and analyzed for testing consistency, computing rule ordering, and answering queries. Imprecise observations are incorporated using qualitative versions of Jeffrey's rule and Bayesian updating, with the result that coherent belief revision is embodied naturally and tractably. Finally, causal rules are interpreted as imposing Markovian conditions that further constrain world rankings to reflect the modularity of causal organizations. These constraints are shown to facilitate reasoning about causal projections, explanations, actions and change. (shrink)

On an attractive, naturalistically respectable theory of intentionality, mental contents are a form of measurement system for representing behavioral and psychological dispositions. This chapter argues that a consequence of this view is that the content/attitude distinction is measurement system relative. As a result, there is substantial arbitrariness in the content/attitude distinction. Whether some measurement of mental states counts as characterizing the content of mental states or the attitude is not a question of empirical discovery but of theoretical utility. If correct, (...) this observation has ramifications in the theory of rationality. Some epistemologists and decision theorists have argued that imprecise credences are rationally impermissible, while others have argued that precise credences are rationally impermissible. If the measure theory of mental content is correct, however, then neither imprecise credences nor precise credences can be rationally impermissible. (shrink)

Cosmology raises novel philosophical questions regarding the use of probabilities in inference. This work aims at identifying and assessing lines of arguments and problematic principles in probabilistic reasoning in cosmology. -/- The first, second, and third papers deal with the intersection of two distinct problems: accounting for selection effects, and representing ignorance or indifference in probabilistic inferences. These two problems meet in the cosmology literature when anthropic considerations are used to predict cosmological parameters by conditionalizing the distribution of, e.g., the (...) cosmological constant on the number of observers it allows for. However, uniform probability distributions usually appealed to in such arguments are an inadequate representation of indifference, and lead to unfounded predictions. It has been argued that this inability to represent ignorance is a fundamental flaw of any inductive framework using additive measures. In the first paper, I examine how imprecise probabilities fare as an inductive framework and avoid such unwarranted inferences. In the second paper, I detail how this framework allows us to successfully avoid the conclusions of Doomsday arguments in a way no Bayesian approach that represents credal states by single credence functions could. -/- There are in the cosmology literature several kinds of arguments referring to self- locating uncertainty. In the multiverse framework, different "pocket-universes" may have different fundamental physical parameters. We don’t know if we are typical observers and if we can safely assume that the physical laws we draw from our observations hold elsewhere. The third paper examines the validity of the appeal to the "Sleeping Beauty problem" and assesses the nature and role of typicality assumptions often endorsed to handle such questions. -/- A more general issue for the use of probabilities in cosmology concerns the inadequacy of Bayesian and statistical model selection criteria in the absence of well-motivated measures for different cosmological models. The criteria for model selection commonly used tend to focus on optimizing the number of free parameters, but they can select physically implausible models. The fourth paper examines the possibility for Bayesian model selection to circumvent the lack of well-motivated priors. (shrink)

I discuss the attitude of Jewish law sources from the 2nd–:5th centuries to the imprecision of measurement. I review a problem that the Talmud refers to, somewhat obscurely, as impossible reduction. This problem arises when a legal rule specifies an object by referring to a maximized measurement function, e.g., when a rule applies to the largest part of a divided whole, or to the first incidence that occurs, etc. A problem that is often mentioned is whether there might be hypothetical (...) situations involving more than one maximal value of the relevant measurement and, given such situations, what is the pertinent legal rule. Presumption of simultaneous occurrences or equally measured values are also a source of embarrassment to modern legal systems, in situations exemplified in the paper, where law determines a preference based on measured values. I contend that the Talmudic sources discussing the problem of impossible reduction were guided by primitive insights compatible with fuzzy logic presentation of the inevitable uncertainty involved in measurement. I maintain that fuzzy models of data are compatible with a positivistic epistemology, which refuses to assume any precision in the extra-conscious world that may not be captured by observation and measurement. I therefore propose this view as the preferred interpretation of the Talmudic notion of impossible reduction. Attributing a fuzzy world view to the Talmudic authorities is meant not only to increase our understanding of the Talmud but, in so doing, also to demonstrate that fuzzy notions are entrenched in our practical reasoning. If Talmudic sages did indeed conceive the results of measurements in terms of fuzzy numbers, then equality between the results of measurements had to be more complicated than crisp equations. The problem of impossible reduction could lie in fuzzy sets with an empty core or whose membership functions were only partly congruent. Reduction is impossible may thus be reconstructed as there is no core to the intersection of two measures. I describe Dirichlet maps for fuzzy measurements of distance as a rough partition of the universe, where for any region A there may be a non-empty set of - _A, where the problem of impossible reduction applies. This model may easily be combined with probabilistic extention. The possibility of adopting practical decision standards based on -cuts is discussed in this context. I propose to characterize the uncertainty that was presumably capped by the old sages as U- uncertainty, defined, for a non-empty fuzzy set A on the set of real numbers, whose -cuts are intervals of real numbers, as U = 1/h 0 h log [1+]d, where h is the largest membership value obtained by any element of A and is the measure of the -cut of A defined by the Lebesge integral of its characteristic function.

A familiar interpretation of quantum mechanics (one of a number of views sometimes labeled the "Copenhagen interpretation'"), takes its empirical apparatus at face value, holding that the quantum wave function evolves by the Schrödinger equation except on certain occasions of measurement, when it collapses into a new state according to the Born rule. This interpretation is widely rejected, primarily because it faces the measurement problem: "measurement" is too imprecise for use in a fundamental physical theory. We argue that this (...) is a weak objection, as there may be many ways of making "measurement" precise. However, measurement-collapse interpretations face a more serious objection: a dilemma tied to the quantum Zeno effect. Is measurement itself an observable that can enter superpositions? If yes, then the standard measurement-collapse dynamics is ill-defined. If no, then (at least if measurement is an observable), measurements can never start or finish. The best way out is to deny that measurement is an observable, but this leads to strong and revisionary consequences. This reinforces the view that there is no nonrevisionary interpretation of quantum mechanics. (shrink)

This commentary highlights the observation that social motivation is usually an imprecisely specified construct. We suggest four social motivation conceptualizations across levels of analysis and explore where the target article situates among these. We then offer theoretical and practical guidance for operationalization and measurement of social motivation to support more comprehensive future research on this complex construct in the autism literature.

The finite age of the universe and the existence of cosmological horizons provides a strong argument that the observable universe represents a finite causal region with finite material and informational resources. A similar conclusion follows from the holographic principle. In this paper I address the question of whether the cosmological information bound has implications for fundamental physics. Orthodox physics is based on Platonism: the laws are treated as infinitely precise, perfect, immutable mathematical relationships that transcend the physical universe and remain (...) totally unchanged by physical processes, however extreme. If instead the laws of physics are regarded as akin to computer software, with the physical universe as the corresponding hardware, then the finite computational capacity of the universe imposes a fundamental limit on the precision of the laws and the specifiability of physical states. That limit depends on the age of the universe. I examine how the imprecision of the laws impacts on the evolution of highly entangled states and on the problem of dark energy. (shrink)

The relational interpretation of quantum mechanics (RQM) has received a growing interest since its first formulation in 1996. Usually presented as an interpretational layer over the usual quantum mechanics formalism, it appears as a philosophical perspective without proper mathematical counterparts. This state of affairs has direct consequences on the scientific debate on RQM which still suffers from misunderstandings and imprecise statements. In an attempt to clarify those debates, the present paper proposes a radical reformulation of the mathematical framework of (...) quantum mechanics which is relational from the start: fact-nets. The core idea is that all statements about the world, facts, are binary entities involving two systems that can be symmetrically thought of as observed and observer. We initiate a study of the fact-nets formalism and outline how it can shed new relational light on some familiar quantum features. (shrink)

The paper presents both new data and a new analysis of the semantic and pragmatic properties of the class of absolute scalar adjectives within an extension of a well-known logical framework for the analysis of gradable predicates: the delineation semantics framework . It has been long observed that the context-sensitivity, vagueness and gradability features of absolute scalar predicates give rise to certain puzzles for their analysis within most, if not all, modern formal semantic frameworks. While there exist proposals for solving (...) these puzzles within other major frameworks , it has been argued that some of their aspects are particularly challenging for the analysis of absolute scalar predicates within the delineation approach. By combining insights into the relationship between context-sensitivity and scalarity from the DelS framework with insights into the relationship between tolerance/similarity relations and the Sorites paradox from Cobreros et al.’s Tolerant, Classical, Strict framework, I propose a new logical system, called Delineation TCS , in which to set analyses of four classes of adjectival predicates. I argue that this new framework allows for an analysis of absolute scalar adjectives that answers these challenges for delineation-based frameworks, while still preserving the heart of the Klein-ian approach.

We explore which types of probabilistic updating commute with convex IP pooling. Positive results are stated for Bayesian conditionalization, imaging, and a certain parameterization of Jeffrey conditioning. This last observation is obtained with the help of a slight generalization of a characterization of externally Bayesian pooling operators due to Wagner :336–345, 2009). These results strengthen the case that pooling should go by imprecise probabilities since no precise pooling method is as versatile.

Our program is ambitious, as is any attempt to match life (in our case real science) with virtue (e.g., exactness). We want our semantics to be not only simia mathematicae but also ancilla scientiae: built more geometrico and at the same time relevant, nay useful, to live science. The goal of exactness may sound arrogant but is actually modest, for the more we rigorize the more we are forced to leave out of consideration, at least for the time being. As (...) to the service intention: we should try to be of some help to science because the latter faces semantic problems but has no tools of its own for solving them. If it had such tools scientists would not engage in spirited polemics over matters of sense and reference, as they often do. Witness the debates on whether the relativistic and quantum theories are concerned with sentient observers, whether population genetics refers to populations taken as wholes, whether psychology is actually concerned with the brain, and whether the sense of a theory is excreted by its mathematical formalism or is determined by the way the theory is tested.A semantics of science should help settle these and similar issues. Moreover it should give sound advice as to how to formulate scientific theories so as to avoid such imprecisions and ambiguities as may give rise to debates of the kind. Constructing such a semantics, both exact and relevant to science, should be more rewarding than either manufacturing neat but irrelevant theories or pursuing erratic polemics on meaning and meaning changes.

Price discrimination is widespread in the American economy and sometimes can be defended as achieving socially preferable economic outcomes. However, the separation of markets required for price discrimination is often difficult to sustain. Sometimes those whom the seller wishes to charge higher prices are identified by imprecise markers. (Thus, as one example, airlines have traditionally attempted to identify business travelers willing to pay higher fares as those travelers unwilling to stay at their destination over a Saturday night.) Imprecise (...) targeting complicates efforts to prevent strategies of circumvention and sellers sometimes resort to claiming that buyers are morally bound to observe rules which sellers cannot otherwise enforce. This paper examines whether buyers can be morally bound by sellers to put themselves into discriminated-against classes.This paper takes the position that if, as often seems to be the case, there is a social consensus that consumers would not be morallyobliged to sort themselves into categories precisely designed to achieve the goals of price discrimination, then there is, a fortiori,a social consensus that consumers are not morally obliged to sort themselves into categories which are only crudely designed toachieve the goals of price discrimination, and which may in fact be counterproductive.

Race or ethnic identity, despite its imprecise categorization, is a useful means of identifying population differences in mechanisms of disease and treatment effects. Therefore, race and other arbitrary demographic and physiological variables have appropriately served as a helpful guide to clinical management and to clinical trial participation. The African-American Heart Failure Trial was carried out in African-Americans with heart failure because prior data had demonstrated a uniquely favorable effect in this subpopulation of the drug combination in BiDil. The remarkable (...) effect of the drug in reducing mortality in this study has illuminated an important new mechanism of therapy for heart failure. Application of these findings need not be confined to the population studied, but the observation highlights the need for more precise ways to identify individual responsiveness to therapy. (shrink)

Despite the hadiths and narratives that warn about the interpretation of the Qur’ān by opinion, the question of how Qur’ānic verses can be understood is about the nature of Qur’ānic exegesis. These narratives, which limit the interpretation to the exact field and indicate the invalidity of the specification of the intention with the imprecise information, bring with it the question of how to understand the Qur’ān in each period and society. The issue that has been questioned in the frame (...) of the commentary from the earliest periods is based on the possibility of commenting besides the narration and defining the area that the thought belongs to the commentator. In this context, it is seen that the distinction between the conceptualization of tafsīr-taʾwīl words in classical commentary literature deals with the subject of the tafsīr, their belongings, epistemological values and contexts. Mainly, this study will question whether authors who do not distinguish between tafsīr-taʾwīl categorize the information about commentary in a different context, then it will analyze two basic approaches on tafsīr and taʾwīl. In the paper, it will be suggested that these classifications in the classical literature should be evaluated together within the framework of the search for methodology in exegesis. Summary: The Prophet, who was the first glossator of the Qur’ān, forbade people to talk about the Qur’ān with their own judgments. The prominent people of the companions refused to comment on some words that were closed in meaning (garīb). The words quoted from Abū Bakr and ʿUmar on this subject are quite famous. However, the Qur’ān is a universal book revealed to be understood in all ages and geographies till the doomsday. The fact that all the verses were not interpreted by the Prophet, and the expansions of meaning observed in the Qur’ān wording necessitate the interpretation of the Qur’ān. The fact that the Prophet forbade people to talk with their own judgments about the Qur’ān and the necessity of understanding the Qur’ān in every era constitutes a dilemma that must be explained. The resolution of this issue will both determine the legitimacy of tafsīr (interpretation) and reveal the difference between the Prophet's tafsīr and the tafsīrs by other people. In this context, a distinction was made between the interpretations of the Prophet and of the companions who witnessed the revelation period from the Tabarī (d. 310/923) in the classical tafsīr literature and the interpretations by glossators in terms of their bindingness and information values. Thus, before even starting the interpretation, glossators questioned the possibility of interpretation of the Qur’ān without the tafsīr of the Prophet and the narratives from the companions that have the force of hadith marfūʿ.It is seen in classical tafsīr literature that distinctions between the tafsīr of the Prophet and the interpretations of the glossator are usually constructed on the terms of tafsīr and ta'wil, to which terminological meanings are attributed. In this regard, the methodology of Māturīdī (d. 333/944) is quite specific and clear. According to Māturīdī, tafsīr is an exact field. Only the tafsīr of the Prophet and the narratives of the companions that have the force of marfūʿ can be included in this field. Taʾwīl, on the other hand, is an area based on supposing. Preferences to be made from possible meanings are supposition and related to taʾwīl. The fact that Māturīdī included the explanations of the Prophet and his companions in the tafsīr field and stated that they expressed exact information shows that he regarded this information in the value of the statement of mutakallim. The data included in the field of taʾwīl are not as the data included in the field of tafsīr in terms of their bindingness and information value. The interpretations made in the field of taʾwīl include supposition; so they cannot be attributed to the desire of God. The field that the Prophet forbade people from declaring their own views is the field of tafsīr in the methodology of Māturīdī. The exactness of this field is an indication that the tafsīr is related to God's desire. It is not right to declare an opinion with supposition in the field that is exact and definite. Even though the interpretation in the field of tafsīr is in accordance with the truth, this cannot eliminate the responsibility of the interpreter that make determinations based on supposition in the exact and definite field. Some scholars, such as Qushayrī (d. 465/1072), also classify the narrative-sagacity areas by means of tafsīr-taʾwīl concepts. This classification deals with the data that is the subject of tafsīr in terms of their belongingness. Indeed, tafsīr science includes both the data that are linked with transmission and non-transmittable elements that can be achieved by following a methodology. Non-transmittable elements included in the taʾwīl field by those who make a distinction between tafsīr and taʾwīl based on narrative-sagacity are the meanings reached through linguistic efforts. Language is an element that holds possibilities in itself. Considering closeness of meaning, multi-meanings, metaphors and allusions in the wording, it can be thought that the meanings reached by linguistic methods include supposition. In the methodology of Māturīdī, the field of tafsīr is composed of the explanations of the Prophet and the narratives of the companions who witnessed the revelations while in the classifications of those who make a distinction between tafsīr and taʾwīl based on narrative-sagacity, tafsīr generally includes narratives. When the issue is handled within the framework of the desire of God and the statements of the mutakallim, it seems that the classification of Māturīdī is more punctual. However, it is understood that this approach does not give a satisfactory answer to the subsequent situations and bindingness of the mentioned data. In the classifications based on narrative-sagacity, the narratives in the field of tafsīr are taken as a whole without analyzing their health grades and their signification. However, some of these narrations are not authentic; so, in this respect it is a problematic issue that they are the subjects of the field of tafsīr. Besides, sometimes there can be different narrations about the tafsīr of verses from the companions. The evaluation these narratives in a field attributed to the desire of God may also pose a problem. The linguistic data that both Māturīdī and those who make a distinction between tafsīr and taʾwīl based on narrative-sagacity include in the field of taʾwīl does not appear to have a homogeneous structure -as is the case with the narratives-. Indeed, among this data, there are elements whose meanings are quite hard to determine as well as firm ones that possibly have only one meaning. It is controversial that these expressions, which have only one meaning and to the validity of whose meaning other evidence point out are included in the field of taʾwīl.The distinction between meaning and interpretation fields in tafsīr is very important in terms of tafsīr methodology. This field designation is in a way a description of nature of the science of tafsīr. Thus, in matters where the human intelligence remains insufficient with the tafsīr narratives from the Prophet, the bindingness of the narratives from the companions are clarified; furthermore, beyond the narrative, the validity and the information values of interpretations of the glossator are determined. In this regard, the tafsīr-taʾwīl distinctions made in the classical tafsīr literature provide us with a rich content and a multifaceted point of view. However, when addressed separately, these distinctions present a number of problems in terms of scope and applicability. Our study proposes the evaluation of tafsīr-taʾwīl distinctions in classical literature together while the meaning-interpretation fields are specified in the framework of the search for methodology in tafsīr. Thus, the incomplete aspects of the classification will be eliminated and a much more comprehensive and functional classification will be achieved. At this point, the methodologies of some figures as Tabarī, who is known to have used the terms of tafsīr and taʾwīl in the same meaning, must also be evaluated separately. Indeed, when the works of these names are analyzed, it is seen that these names also distinguish the meaning-interpretation fields in tafsīr, but they do not do this through the tafsīr-taʾwīl concepts.

Vagueness is understood as the problem of associating imprecise application criteria with ordinary predicates such as ‘bald’ or ‘blue’. It is often construed as due to one’s tolerance to a minute difference in forming a verdict on the application of a vague predicate.

The findings suggest a negative (...) effect of tolerance on categorisation with vague predicates. The implication of the findings for certain commonly-held assumptions about tolerance is discussed.

Because it fails to solve the wave-particle problem, orthodox quantum theory is obliged to be about observables and not quantum beables. As a result the theory is imprecise, ambiguous, ad hoc, lacking in explanatory power, restricted in scope and resistant to unification. A new version of quantum theory is needed that is about quantum beables.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Theories of Emotion: Expressing, Feeling, Acting by Pia CAMPEGGIANISabrina B. LittleCAMPEGGIANI, Pia. Theories of Emotion: Expressing, Feeling, Acting. New York: Bloomsbury Publishing, 2023. xiv + 199 pp. Cloth, $80.89; paper, $21.60In Theories of Emotion, Pia Campeggiani provides a philosophical introduction to the emotions. The book is multidisciplinary and empirically informed. It is organized around three “groundbreaking intuitions” of emotion theory—(1) expression, (2) subjectivity, and (3) action. Each section (...) corresponds to a different thinker—Charles Darwin, William James, and John Dewey, respectively—and each section concludes with a discussion of relevant debates. This book is outstanding. It is clearly written, well organized, and impressive in its scope. In what follows, I outline key ideas and raise questions generated by each section, then conclude with general reflections on the text.Campeggiani begins with the “scandal” of emotion research: There is no agreement about what an emotion is. In part, this lack of consensus is due to the imprecise ways we employ concepts like feelings, emotions, affect, and passions in ordinary discourse. In part, it is due to empirical difficulties. For example, Campeggiani describes how implicit assumptions and a forced-choice format compromised an experiment about expression universality.Additionally, Campeggiani points out that the category “emotions” has an internal structure that lacks clear-cut boundaries. There are paradigmatic examples of emotions, such as fear and anger, but there are also ambiguous phenomena, such as respect and modesty, which we may or may not recognize as such. Throughout the text, Campeggiani introduces and evaluates numerous accounts of emotions, drawing our attention to the strengths, limitations, and empirical adequacy of each.Part 1 begins with Charles Darwin’s contributions to emotion theory—an emphasis on the biological origins of emotions and a focus on expression. This section examines emotions in connection to adaptive fitness, exploring phenomena such as blushing when we are ashamed and the biological bases of emotions. A highlight of this section is an exploration of the social or communicative character of the emotions, which Darwin described as “only a secondary effect” of expression. Campeggiani examines emotional contagion and imitation, as well as the [End Page 141] phenomenon of feeling more pain when we express pain on our faces. There is also a rich discussion about constructionism as an alternative to basic emotions theory.Part 2 opens with William James on subjective experience. Campeggiani describes the limitations of James’s position—of understanding emotions to be reducible to feelings. For starters, this position is not empirically well supported. Campeggiani cites Walter Cannon’s observation that “many of the autonomic changes that are symptomatic of a given emotion can also occur in its absence.” Additionally, James fails to “properly flesh out the link between emotions and evaluations.” Campeggiani then describes the cognitive turn in emotion theory that emerged in response to the lack of attention paid to evaluation. Cognitive accounts of emotion deemphasize the bodily dimensions of emotional experiences in favor of the intentional properties, or “aboutness,” of emotions. Emotions see things as things.From my vantage, this was the best part of the book. Campeggiani highlights Damasio’s point that decision-making depends on having a “correct affective perception of the values at stake in a given situation.” For instance, feeling outsized or misdirected fear may undermine our decision-making. Campeggiani also introduces debates about whether emotions are appraisals, and whether emotions entail judgments or make judgments more likely. In the introduction, she mentions that “decision-making processes are always and inevitably underpinned by emotions, for good and for ill.” We see what she means in this section. Emotions participate in reason, impede reason, and have cognitive content themselves.That emotions involve or participate in our judgments raises two kinds of concerns—epistemic and normative. The epistemic worry is that inaccurate appraisals may undermine our understanding of the world. This is especially worrisome for the class of emotions Campeggiani calls “recalcitrant,” or closed off to other mental states, and for the emotions she says are “heavily influenced by our needs and goals.” Emotions are imperfectly truth-tracking, as was made clear earlier, in part 1, regarding their adaptive nature. The normative worry is that certain emotional... (shrink)

Previous research on moral dilemmas has mainly focused on decisions made under conditions of probabilistic certainty. We investigated the impact of uncertainty on the preference for action (killing one individual to save five people) and inaction (saving one but allowing five people to die) in moral dilemmas. We reported two experimental studies that varied the framing (gain vs loss), levels of risk (probability of gain and loss) and levels of ambiguity (imprecise probability information) in the choice to save five (...) individuals by sacrificing one. We found that participants preferred actions with uncertainty (risk/ambiguity) over inaction. Specifically, we found that participants preferred actions with precise probability information (risk) over inaction, and they preferred actions with modest or high levels of ambiguity over actions with precise probabilities, especially when moral dilemmas had a loss frame. We also observed commission bias in Study 2. We discussed the implications for research in moral decision-making. (shrink)

Much of what we know about cognitive mapping comes from observing how biological agents behave in their physical environments, and several of these ideas were implemented on robots, imitating such a process. In this paper a novel approach to cognitive mapping is presented whereby robots are treated as a species of their own and their cognitive mapping is being investigated. Such robots are referred to as Albots. The design of the first Albot, Albot0, is presented. Albot0 computes an imprecise (...) map and employs a novel method to find its way home. Both the map and the return-home algorithm exhibited characteristics commonly found in biological agents. What we have learned from Albot0’s cognitive mapping are discussed. One major lesson is that the spatiality in a cognitive map affords us rich and useful information and this argues against recent suggestions that the notion of a cognitive map is not a useful one.

The number of elements in a small set of items is appraised in a fast and exact manner, a phenomenon called subitizing. In contrast, humans provide imprecise responses when comparing larger numerosities, with decreasing precision as the number of elements increases. Estimation is thought to rely on a dedicated system for the approximate representation of numerosity. While previous behavioral and neuroimaging studies associate subitizing to a domain-general system related to object tracking and identification, the nature of small numerosity processing (...) is still debated. We investigated the neural processing of numerosity across subitizing and estimation ranges by examining electrophysiological activity during the memory retention period in a delayed numerical match-to-sample task. We also assessed potential differences in the neural signature of numerical magnitude in a fully non-symbolic or cross-format comparison. In line with behavioral performance, we observed modulation of parietal-occipital neural activity as a function of numerosity that differed in two ranges, with distinctive neural signatures of small numerosities showing clear similarities with those observed in visuospatial working memory tasks. We also found differences in neural activity related to numerical information in anticipation of single vs. cross-format comparison, suggesting a top-down modulation of numerical processing. Finally, behavioral results revealed enhanced performance in the mixed-format conditions and a significant correlation between task performance and symbolic mathematical skills. Overall, we provide evidence for distinct mechanisms related to small and large numerosity and differences in numerical encoding based on task demands. (shrink)

Traces are generally considered to constitute an ontologically distinct class of objects that can be distinguished from other objects. However, it can be observed on close inspection that the principles to demarcate traces from other objects are quite general, imprecise and intuitively unclear, except perhaps the entropic account envisaging traces as low entropy states. This view was developed by Hans Reichenbach, Adolf Grünbaum, and J. J. C. Smart on the basis of Reichenbach's theory of branch systems that are subsystems (...) of wider systems. According to this theory, traces form within subsystems as low entropy states as a result of interaction with wider systems. It is also claimed that entropy is the measure of disorder, and that traces are ordered states. I argue that the concepts of entropy and disorder are used beyond their legitimate limits of application, for there are clear-cut counter-examples in the literature. I also analyze the concept of trace together with some examples from classical mechanics and geology in order to show that traces are determined relative to a particular context in which they are so defined.

Research and writing at the intersection of faith and medicine by now include thousands of published studies, review articles, books, chapters, and essays. Yet this emerging field has been described, from within, as disheveled on account of imprecision and lack of careful attention to conceptual and theoretical concerns. An important source of confusion is the fact that scholarship in this field constitutes two distinct literatures, or rather meta-literatures, which can be termed faith as a problematic for medicine and medicine as (...) a problematic for faith. These categories represent distinct theoretical lenses for viewing the intersection of faith and medicine. Observations about these two approaches are offered, along with insights about why the discourse on faith and medicine should become better integrated into discussions of religion and science.

Psychosis is associated with distorted perceptions and deficient bottom-up learning such as classical fear conditioning. This has been interpreted as reflecting imprecise priors in low-level predictive coding systems. Paradoxically, overly strong beliefs, such as overvalued beliefs and delusions, are also present in psychosis-associated states. In line with this, research has suggested that patients with psychosis and associated phenotypes rely more on high-order priors to interpret perceptual input. In this behavioural and fMRI study we studied two types of fear learning, (...) i.e., instructed fear learning mediated by verbal suggestions about fear contingencies and classical fear conditioning mediated by low level associative learning, in delusion proneness—a trait in healthy individuals linked to psychotic disorders. Subjects were shown four faces out of which two were coupled with an aversive stimulation while two were not in a fear conditioning procedure. Before the conditioning, subjects were informed about the contingencies for two of the faces of each type, while no information was given for the two other faces. We could thereby study the effect of both classical fear conditioning and instructed fear learning. Our main outcome variable was evaluative rating of the faces. Simultaneously, fMRI-measurements were performed to study underlying mechanisms. We postulated that instructed fear learning, measured with evaluative ratings, is stronger in psychosis-related phenotypes, in contrast to classical fear conditioning that has repeatedly been shown to be weaker in these groups. In line with our hypothesis, we observed significantly larger instructed fear learning on a behavioural level in delusion-prone individuals compared to non-delusion-prone subjects. Instructed fear learning was associated with a bilateral activation of lateral orbitofrontal cortex that did not differ significantly between groups. However, delusion-prone subjects showed a stronger functional connectivity between right lateral orbitofrontal cortex and regions processing fear and pain. Our results suggest that psychosis-related states are associated with a strong instructed fear learning in addition to previously reported weak classical fear conditioning. Given the similarity between nocebo paradigms and instructed fear learning, our results also have an impact on understanding why nocebo effects differ between individuals. (shrink)

The phenomenon of misconduct in scientific research illustrates how great can be the social damage of not knowing the incidence of a malady. Many urgings about such phenomenon have predicated views about the extent of institutional and governmental vigilance on observers' differing surmises about how frequently misconduct occurs. Such is the measurement error of extant data about incidence1 that one can venture little more than the deliberately imprecise conclusion that “misconduct is neither common nor rare.”.

This paper is about Sobel sequences, which are sequences of counterfactuals that supposedly display two interesting properties: first, they are consistent, as accounted for by the famous Lewis-Stalnaker analysis; but second, they are not consistent in the reverse order, which is not accounted for by Lewis-Stalnaker. I argue that there has been an empirical oversight in the literature on these sequences: there are consistent sequences, and there are irreversible sequences, but no sequence is both. The Lewis-Stalnaker theory neatly captures Sobel (...) sequences, and also captures the inconsistency of Lewis sequences. But there is still a dynamic asymmetry at work with Lewis sequences, which I account for by appeal to the pragmatic phenomenon of imprecision. Lewis sequences seem consistent because they do not belie factual disagreements, but rather metalinguistic disagreements about how precise to be. This also accounts for their irreversibility—such metalinguistic disagreements about the standard of precision are only possible in one direction, as famously observed by Lewis, who observed them in discourses not containing counterfactuals.

Research into expertise is relatively common in cognitive science concerning expertise existing across many domains. However, much less research has examined how experts within the same domain assess the performance of their peer experts. We report the results of a modified think-aloud study conducted with 18 pilots . Pairs of same-ranked pilots were asked to rate the performance of a captain flying in a critical pre-recorded simulator scenario. Findings reveal considerable variance within performance categories, differences in the process used as (...) evidence in support of a performance rating, different numbers and types of facts identified, and differences in how specific performance events affect choice of performance category and gravity of performance assessment. Such variance is consistent with low inter-rater reliability. Because raters exhibited good, albeit imprecise, reasons and facts, a fuzzy mathematical model of performance rating was developed. The model provides good agreement with observed variations. (shrink)

L'idée que comprendre permet de prévoir est une idée moderne. Elle est fondée sur la découverte, que le monde physique obéit à des lois (Galilée, et surtout Newton). Elle a mis fin à la pensée magique, et elle est à la base de la révolution scientifique et du monde moderne. Or nous assistons à la dissociation de ces deux choses. D'une part, on réalise par exemple que les lois mathématiques de certains phénomènes, mêmes parfaitement connues, sont si sensibles à la (...) moindre imprécision dans les données que cela rend la prévision impossible en pratique. C'est le fameux "effet papillon" : un battement d'ailes à Rio pourrait être la cause d'une tornade au Texas. D'un autre côté, la puissance des big data rendrait inutile, selon certains essayistes et quelques scientifiques, le raisonnement théorique. On n'aurait plus besoin de comprendre les causalités puisque la corrélation suffirait. Un retour au CASSINI Moyen Age en somme, aux recettes qui ont marché, mais avec des données des millions de fois plus nombreuses. En termes économiques, on a découvert avec la révolution scientifique qu'une explication théorique coûtait moins cher que certaines observations : Newton avait prévu l'aplatissement de la Terre sans qu'on ait besoin d'aller voir aux pôles ; aujourd'hui grâce à la rapidité des ordinateurs et des réseaux, les termes de la comparaison s'inversent. A ceci, Hubert Krivine répond notamment que les big data et l'intelligence artificielle qui se fonde sur elles sont conservatrices, et que si elles conviennent aux assureurs, elles ne peuvent pas prévoir des choses nouvelles et extraordinaires. Les ordinateurs composent aujourd'hui sur demande du Mozart ou des ballades celtiques, aucun n'invente de musique nouvelle. Ils conduisent des voitures, mais aucun n'explique le mystère de la "matière noire". La machine peut aider l'homme, elle ne le remplacera pas. (shrink)

In previous works we have established that the spacetime probabilistic organization of the quantum theory is determined by the spacetime characteristics of the operations by which the observer produces the objects to be studied (“states” of microsystems) and obtains qualifications of these. Guided by this first conclusion, we have then built a “general syntax of relativized conceptualization” where any description is explicitly and systematically referred to the two basic epistemic operations by which the conceptor introduces the object to be qualified (...) and then obtains qualifications of it. Inside this syntax there emerges a general typology of the relativized descriptions. Here we show that with respect to this typology the type of the predictive quantum mechanical descriptions acquires a precise definition. It appears that the quantum mechanical formalism has captured and has expressed directly in a mathematical language the most complex form in which can occur a first descriptional phase that lies universally at the bottom of any chain of conceptualization. The main features of the Hilbert-Dirac algorithms are decoded in terms of the general syntax of relativized conceptualization. This renders explicit the semantical contents of the quantum mechanical representations relating each one of these to its mathematical quantum mechanical expression. Basic insufficiencies are thus identified and, correlatively, false problems as well as answers to these, or guides toward answers. Globally the results obtained provide a basis for future attempts at a general mathematical representation of the processes of conceptualization. “Il pourrait, en effet, être dangereux pour l'avenir de la Physique qu'elle se contente trop facilement de purs formalismes, d'images floues et d'explications toutes verbales s'exprimant par des mots à signification imprécise”—Louis de Broglie,Certitudes et Incertitudes de la Science (Albin Michel, Paris, 1965).

In lieu of an abstract, here is a brief excerpt of the content:94 HUME ON THE PERCEPTION OF CAUSALITY Introduction Few issues in philosophy have generated as much debate and as little agreement as Hume's controversial theory of causality. The theory itself has been notoriously difficult to pin down, and not surprisingly empirical evidence has played a very minor role in the issue of what is meant by 'cause'. This is not, however, due to the fact that empirical tests of (...) the theory are hard to devise, but rather because such tests have usually been undertaken by experimental psychologists addressing slightly different issues and unaware of the philosophical implications of their work. However, recent signs of agreement on the overall nature of the theory (reviewed in Beauchamp and Rosenberg, chapter 1) allow a profitable integration of the theory with psychological research on the nature and importance of the perception of causal relations in conditioning. The significance of some of these experiments will be discussed later, and it will be argued that the factors Hume cited as being the essential determinants of causality, when complemented by the additional factor of the degree of contingency between the cause and the effect, correspond exactly with the factors known to affect conditioning; and therefore, that the laws of conditioning specify the properties that define causal relationships. Hume's Theory of Causality Hume was well aware of the importance of causal connections between events as a source of associations in the mind: 95 'Tis sufficient to observe, that there is no relation, which produces a stronger connexion in the fancy, and makes one idea more readily recall another, than the relation of cause and effect betwixt their objects (T II).2 In other words, if we believe a causal relationship exists between two events, then one of these events, the cause, will readily recall the other, the effect. The problem comes, of course, when we ask how it is that we know that a causal relationship exists. Obviously, a distinction must be made between causation as a physical property and causality as a mental idea. Traditionally, the following definitions have been made: causation is the physical property of one event causing another, such as one ball colliding with and causing the movement of a second ball. This property is part of the realm of mechanics and physics. Causality, on the other hand, describes the attribution by an organism of an effect to a cause. Such a distinction is supported by dictionary definitions. These two ways of thinking of what is meant by the term 'cause' are explicitly discussed by Hume. On the notion of physical causation, he says: We may define a CAUSE to be 'An object precedent and contiguous to another, and where all the objects resembling the former are plac'd in like relations of precedency and contiguity to those objects, that resemble the latter.' Of the mental idea of a causal relationship, on the other hand, he says: A CAUSE is an object precedent and contiguous to another, and so united with it, that the idea of the one determines the mind to form the idea of the other, and the impression of the one to form a more lively idea of the other. (T 170) Unfortunately, Hume was never less than imprecise in maintaining this dissociation, and often 96 he plainly confused the two definitions. Hence the academic controversy, between those who, like Kemp Smith, believe that the second definition represents a misguided attempt by Hume to analyse the causal relation on a mental level, 3 and those who see both definitions as essential (e.g. Beauchamp and Rosenberg). But surely the first definition simply represents Hume's view of causality as a philosophical relation, while the second represents his view of it as a psychological fact. And it is as much his intention to explain this fact, that ideas do not simply come into our heads for no apparent reason, but on the contrary are summoned up by preceding thoughts which they are associated, as it is to elucidate the philosophical relation. The extent of Hume's commitment to a psychological explanation of causal attribution has been recognised by Beauchamp and Rosenberg: 5 Hume plainly did develop a theory of causal... (shrink)

Discrete choice experiments (DCE) are often used to elicit preferences, for instance, in health preference research. However, DCEs only provide binary responses, whilst real-life choices are made with varying degrees of conviction. We aimed to verify whether eliciting self-reported convictions on a 0–100 scale adds meaningful information to the binary choice. Eighty three respondents stated their preferences for health states using DCE and the time trade-off method (TTO). In TTO, utility ranges were also elicited to account for preference imprecision. We (...) verified the properties of the conviction across three areas: (1) response to various choice task modifications (e.g. dominance, increase in complexity, distance from the status quo) and association with rationality violations (e.g. intransitivity); (2) association with test–retest results; (3) relation to the utility difference and imprecision estimated in TTO. Regarding (1), conviction increased in choice tasks with lower complexity, larger relative attractiveness, and lower distance to the status quo. Regarding (2), choices made with above-median conviction were sustained in 90% of the cases, compared to 68% for below-median conviction. Regarding (3), the conviction increases with utility difference and it decreases with utility imprecision; overconfidence seems to prevail: non-zero conviction is reported even for identical utilities. Self-reported conviction in DCE is associated in an intuitive way with the observed choices. It may, therefore, be useful in explaining or predicting behaviour or bridging the gap between the results of various elicitation tasks. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Late-Marxist, Post-Poststructuralist Critical NebulosityWendell V. HarrisIllustration, by J. Hillis Miller; 168 pp. Cambridge: Harvard University Press, 1992, $35.00.The title of J. Hillis Miller’s Illustration is apt in a way other than the author anticipated: it is a composite illustration of most of what makes so much of contemporary literary and aesthetic criticism unsatisfying if not nugatory. Initial evidence of the lack of cogent conceptualization is the disparateness of the (...) two long essays jammed between the covers of the book. Part One is entitled “The Work of Cultural Criticism in the Age of Digital Reproduction” and Part Two “Word and Image.” Miller explains the relationship by saying what while the first section of the book “will attempt to understand” the shift in literary studies toward theory and especially cultural studies, the second section “will explore the relations of picture to word as one practical and theoretical issue important to cultural studies” (p. 9). But that connection is (fleetingly) asserted in the midst of an argument so fragmented and confused that whole sections must here be passed over without comment.What is most striking about Part One is the thought-disabling imprecision of many of the key terms and the not unrelated way in which the argument follows well-travelled modes of Marxist and poststructuralist thought. The title of Part One, “The Work of Cultural Criticism in the Age of Digital Reproduction,” is of course intended to [End Page 127] link Miller’s first essay to what is probably the best-known of Walter Benjamin’s essays, “The Work of Art in the Age of Mechanical Reproduction.” Both seek not only to link changing technological possibilities to the direction of cultural change, but to suggest that such changes should be harnessed to the work of political revolution. Miller might have been warned by the deficiencies of Benjamin’s over-rated essay. Benjamin begins his essay by applauding Marx for so cogently showing “what could be expected of capitalism in the future”: the prophecy Benjamin derives from Marx is “that one could expect [capitalism] not only to exploit the proletariat with increasing intensity, but ultimately to create conditions which would make it possible to abolish capitalism itself” (p. 217). 1 There is still plenty of exploitation to be found in the world, not excluding the most economically (capitalistically) developed countries, but it requires real intellectual contortions to argue that the growth and exploitation of a proletariat has increased where capitalism has most developed; the assertion that the world is moving toward the abolition of capitalism hardly requires comment.Benjamin’s closing argument, the point toward which his entire essay is presumably driving, substitutes a clever slogan for thought. “The logical result of Fascism is the introduction of aesthetics into political life” (p. 241). But, writes Benjamin in his closing sentence, “Communism responds by politicizing art” (p. 242). Miller attempts to explain the distinction: “To aestheticize politics is to treat the state as though it were a work of art” while the “politicizing of art... means affirming the political value and force of art” (p. 10). Well, it is of course possible to assume such a meaning for Benjamin’s words, especially since it is hard to know exactly what they mean, but why make so much of an essay which begins by endorsing a prophecy that has become increasingly dubious, ends in an ambiguous formulation, and in between mixes obvious and trivial observations with a highly questionable argument about the disappearance of the “aura” of a work as a result of mechanical reproduction? As for the latter, the cheap reproduction of, for example, certain of Van Gogh’s paintings can be argued to “debase” them, but if they mean little to those who encounter them only on cheap posters or computer screens, they can scarcely mean less than they did to those unaware of their existence before the age of mechanical reproduction. And after all, if the original paintings have not retained their “aura,” museums could simply fill their rooms with reproductions.The reason Miller links his essay to that of Benjamin is presumably to demonstrate his allegiance to the form of Marxist thought so frequently...

In lieu of an abstract, here is a brief excerpt of the content:The Rebirth of Cool:Toward a Science SublimeE. David Wong (bio)We love and hate "the cool." As educators, few things are more coveted than being recognized as teaching the "coolest" class in the school. We look forward to the rare moment when students gasp in awe or scream in amazement. However, in the quiet that returns after the last student rushes out the classroom door, we may feel an uneasy (...) ambivalence. Perhaps we admonish ourselves that serious science is substantial, enduring, and intellectual. We wonder whether our "cool" class was merely superficial, fleeting, and mindless.In this article I examine the cool—this idea we love and hate—and assert its importance in science education. I acknowledge that some experiences can be engaging but are superficial and unimportant—this is the "merely cool." By contrast, some experiences are deeply moving because we feel a growing capacity to perceive meaning and value in the world—this is the "sublimely cool." I draw from philosophy, literature, psychology, and aesthetics to build connections between cool and sublime experiences. By highlighting the surprisingly substantial connection between the cool and sublime, I hope to bring greater depth to the meaning of "cool," this imprecise, but honest, term. I also take care to define sublimely cool experiences in science as having a direct relationship with subject-matter understanding. It is true that the full meaning of aesthetic experiences extends beyond the grasp of words and conceptualization; however, it is equally true that knowledge and reason are central to all worthwhile experiences. The expansion of meaning and perception, not just intense sensation or emotion, is the heart of the sublimely cool experience. Nobel laureate physicist Richard Feynman provides a personal example of how his knowledge of science enhances his sublimely cool experience of Nature: "Poets say science takes away from the beauty of the stars—mere globs of gas atoms. Nothing is 'mere.' I too can see the stars on a desert night, and feel them. But do I see less or more? The [End Page 67] vastness of the heavens stretches my imagination—stuck on this carousel my little eye can catch one-million-year-old light."1Cool as a Sign of Compelling Experience"Cool" is an intriguing expression for it is at once both crude and incisive. On the one hand, "cool" is a colloquial term used by people of all ages and backgrounds in many contexts to describe many things. So wide and informal is its use that "cool" may seem trite and banal. "Cool" is rarely chosen carefully when used: indeed, it is more often an unintentional, reflexive utterance.Thus, the more one thinks before speaking, the less likely "cool" will be used. Nonetheless, because it is an impulsive expression, "cool" may be all the more honest. Dewey made a similar point in his observation of the word "beauty": "Beauty... is properly an emotional term, though one denoting a characteristic emotion. In the presence of a landscape, a poem or a picture that lays hold of us with immediate poignancy, we are moved to murmur or to exclaim 'How beautiful.' The ejaculation is a just tribute to the capacity of the object to arouse admiration that approaches worship."2 With "just tribute" Dewey emphasizes the honesty of the term. By "admiration that approaches worship," Dewey reminds us that the spontaneous uttering of "beautiful" is a sign that a powerful experience has been had. I will make a similar argument that the term "cool"—although common and ordinary—can signal the having of a compelling experience. As a compelling experience, the cool becomes an important resource for teachers.Dewey goes on to describe how the meaning of "beauty" has, unfortunately, lost its value to aesthetic theoreticians: "Beauty is at the furthest remove from an analytic term, and hence from a conception that can figure in theory as a means of explanation or classification. Unfortunately, it has been hardened into a peculiar object; emotional rapture has been subjected to what philosophy calls hypostatization, and the concept of beauty as an essence of intuition has resulted. For purposes of theory, it then becomes an obstructive term."3Because of the way they are... (shrink)

We study abductive, causal, and non-causal conditionals in indicative and counterfactual formulations using probabilistic truth table tasks under incomplete probabilistic knowledge (N = 80). We frame the task as a probability-logical inference problem. The most frequently observed response type across all conditions was a class of conditional event interpretations of conditionals; it was followed by conjunction interpretations. An interesting minority of participants neglected some of the relevant imprecision involved in the premises when inferring lower or upper probability bounds on the (...) target conditional/counterfactual ("halfway responses"). We discuss the results in the light of coherence-based probability logic and the new paradigm psychology of reasoning. (shrink)
