The ability to perceive the shapes of things as enduring through changes in how they stimulate our sense organs is vital to our sense of stability in the world. But what sort of capacity is shape constancy, and how is it reflected in perceptual experience? This paper defends a pluralist account of shape constancy: There are multiple kinds of shape constancy centered on geometrical properties at various levels of abstraction, and properties at these various levels feature in the content of (...) perceptual experience, governing patterns of apparent shape similarity. I propose that the varieties of shape constancy are subserved by the syntactic complexity of perceptual shape representations. By assigning discrete constituents to various abstract shape parameters, these representations attune us to the preservation of certain abstract shape properties through changes in more determinate shape properties. Finally, I draw broader lessons concerning the nature and function of perceptual constancy. (shrink)

Causal closure arguments against interactionist dualism are currently popular amongst physicalists. Such an argument appeals to some principles of the causal closure of the physical, together with certain other premises, to conclude that at least some mental events are identical with physical events. However, it is crucial to the success of any such argument that the physical causal closure principle to which it appeals is neither too strong nor too weak by certain standards. In this paper, it is argued that (...) various forms of naturalistic dualism, of an emergentist character, are consistent with the strongest physical causal closure principles that can plausibly be advocated.

A prominent view holds that perception and memory are distinguished at least partly by their temporal orientation: Perception functions to represent the present, while memory functions to represent the past. Call this view perceptual presentism. This chapter critically examines perceptual presentism in light of contemporary perception science. I adduce evidence for three forms of perceptual sensitivity to the past: (i) shaping perception by past stimulus exposure, (ii) recruitment of mnemonic representations in perceptual processing, and (iii) perceptual representation of present objects (...) as possessing past properties. I argue that forms (i) and (ii) are consistent with perceptual presentism, while form (iii) poses a genuine threat to the view. While the empirical case for form (iii) remains inconclusive, I suggest that the most serious challenges to perceptual presentism derive from representations that integrate mnemonic and present-tensed elements in the performance of canonical perceptual functions, such as perceiving object continuity over time.

When we perceive an object, we perceive the object from a perspective. As a consequence of the perspectival nature of perception, when we perceive, say, a circular coin from different angles, there is a respect in which the coin looks circular throughout, but also a respect in which the coin's appearance changes. More generally, perception of shape and size properties has both a constant aspect—an aspect that remains stable across changes in perspective—and a perspectival aspect—an aspect that changes depending on (...) one's perspective on the object. How should we account for the perspectival aspect of spatial perception? We present a framework within which to discuss the perspectival aspect of perception and put forward three desiderata that any account of the perspectival aspect of perception should satisfy. We discuss views on which the perspectival aspect of perception is analyzed in terms of constitutively mind-dependent appearance properties as well as views on which the perspectival aspect of perception is analyzed in terms of representations of mind-independent perspectival properties.

Conceptualism is the view that at least some perceptual representation is conceptual. This paper considers a prominent recent argument against Conceptualism due to Ned Block. Block’s argument appeals to patterns of color representation in infants, alleging that infants exhibit categorical perception of color while failing to deploy concepts of color categories. Accordingly, the perceptual representation of color categories in infancy must be non-conceptual. This argument is distinctive insofar as it threatens not only the view that all perception is conceptual, but (...) also views that restrict the Conceptualist thesis to perceptual categorization. However, I contend that it fails at two stages. Block’s arguments for the perceptual representation of color categories in infancy, and against color concept deployment in infancy, are unpersuasive. Thus, Block has not vanquished Conceptualism. I draw out implications for debates about the perception-cognition border and for the question of whether explicit categorization occurs in perception.

This article develops a view of shape representation both in visual experience and in subpersonal visual processing. The view is that, in both cases, shape is represented in a ‘layered’ manner: an object is represented as having multiple shape properties, and these properties have varying degrees of abstraction. I argue that this view is supported both by the facts about visual phenomenology and by a large collection of evidence in perceptual psychology. Such evidence is provided by studies of shape discriminability, (...) apparent motion, multiple-object tracking, and structure-from-motion. Recent neuroscientific work has also corroborated this psychophysical evidence. Finally, I draw out implications of the layered view for processes of concept acquisition. 1 Introduction2 Metric Properties andShape Properties3 Metric Views4 Against Metric Views of Visual Shape Experience5 The Visual System Uses Abstract Shape Properties6 Against Metric Views of Visual Shape Representation7 Neural Underpinnings of Abstract Shape Perception8 Implications.

It is widely thought that there are limits to how things can perceptually appear to us. For instance, nothing can appear both square and circular, or both pure red and pure blue. Adam Pautz has dubbed such constraints “laws of appearance.” But if the laws of appearance obtain, then what explains them? Here I examine the prospects for an empirical explanation of the laws of appearance. First, I challenge extant empirical explanations that appeal purely to the format of perceptual representation. (...) I then develop a hybrid approach, on which the laws are explained not merely by format, but by two further factors: ecological constraints imposed by our environments, and computational constraints embodied by our perceptual systems. While the hybrid approach implies that the laws of appearance are contingent, I argue that this implication is empirically defensible, since even some of the most intuitively compelling laws have real-world counterexamples.

Molyneux’s question asks whether a person born blind who has learned to identify shapes by touch could, if suddenly granted sight, immediately identify shapes visually. This question has often been used to structure discussions of whether there is a “rational connection” between sight and touch—whether it is possible to rationally doubt whether the same shape properties are both seen and felt. I distinguish two questions under this general heading. The first concerns, roughly, whether the visual and haptic perception of shape (...) is rationally connected in normally sighted perceivers. The second concerns, roughly, whether the visual and haptic perception of shape is rationally connected in all possible perceivers. I argue that real-world implementations of Molyneux’s question are irrelevant to the first question, but potentially relevant to the second. However, I also argue that the second question does not have the philosophical significance it is sometimes claimed to have. In particular, it cannot be used to adjudicate debates about whether the phenomenal character of perceptual experience is primarily determined “externally” by the worldly properties we perceive, or “internally” by physiological or functional properties of our brains.

Christopher Hill's Perceptual experience is a must‐read for philosophers of mind and cognitive science. Here I consider Hill's representationalist account of spatial perception. I distinguish two theses defended in the book. The first is that perceptual experience does not represent the enduring, intrinsic properties of objects, such as intrinsic shape or size. The second is that perceptual experience does represent certain viewpoint‐dependent properties of objects—namely, Thouless properties. I argue that Hill's arguments do not establish the first thesis, and then I (...) raise questions about the Thouless‐property view and its role in Hill's defense of representationalism. (shrink)

Quilty-Dunn et al.'s wide-ranging defense of the Language of Thought Hypothesis (LoTH) argues that vision traffics in abstract, structured representational formats. We agree: Vision, like language, is compositional – just as words compose into phrases, many visual representations contain discrete constituents that combine in systematic ways. Here, we amass evidence extending this proposal, and explore its implications for how vision interfaces with the rest of the mind.

Perceptual representations pick out individuals and attribute properties to them. This paper considers the role of perceptual attribution in determining or guiding perceptual reference to objects. We consider three extant models of the relation between perceptual attribution and perceptual reference–all attribution guides reference, no attribution guides reference, or a privileged subset of attributions guides reference–and argue that empirical evidence undermines all three. We then defend a flexible-attributives model, on which the range of perceptual attributives used to guide reference shifts adaptively (...) with context. This model underscores the remarkable and dynamic intelligence of our perceptual capacities. We elucidate implications of the model for the boundary between perception and propositional thought.

Different authors offer subtly different characterizations of naïve realism. We disentangle the main ones and argue that illusions provide the best proving ground for naïve realism and its main rival, representationalism. According to naïve realism, illusions never involve per- ceptual error. We assess two leading attempts to explain apparent perceptual error away, from William Fish and Bill Brewer, and conclude that they fail. Another lead- ing attempt is assessed in a companion paper, which also sketches an alternative representational account.

When, for example, we say of something that it ‘is an object’, or ‘is an event’, or ‘is a property’, we are engaging in categorial predication: we are assigning something to a certain ontological category. Ontological categorization is clearly a type of classification, but it differs radically from the types of classification that are involved in the taxonomic practices of empirical sciences, as when a physicist says of a certain particle that it ‘is an electron’, or when a zoologist says (...) of a certain animal that it ‘is a mammal’, or when a meteorologist says of a certain weather‐phenomenon that it ‘is a hurricane’. Classifications of the latter types presuppose that the items being classified have already been assigned to appropriate ontological categories, such as the categories of object, species, or event. What do categorial predications mean? How are their truth‐conditions to be determined, and how can those truth‐conditions be known to be satisfied? Do they have truthmakers? Questions like these are amongst those addressed in the present paper. (shrink)

Foundationalism is false; after all, foundational beliefs are arbitrary, they do not solve the epistemic regress problem, and they cannot exist withoutother (justified) beliefs. Or so some people say. In this essay, we assess some arguments based on such claims, arguments suggested in recent work by Peter Klein and Ernest Sosa.

The aim of this dissertation is to convince you that time passes. It is commonly held that a belief in time’s passage is in conflict with relativistic physics and that our phenomenology as of passage is not sufficient reason for us to believe in it. I argue that both of these views are false. Along the way I offer a typology and critique of the existing accounts of passage. I offer my own view of passage, the process view, which requires (...) that we be relationalists about time. I make the case that there is strong reason to endorse relationalism. -/- In Chapter 1, I outline the most common positions in temporal ontology (presentism, eternalism, growing block theory, and the moving spotlight view), which are each committed to two theses: an ontological thesis about what exists, and a second thesis about whether the world is static or dynamic. I argue that the ontological theses are either trivial, not meaningful, or beg the question. I then try to recast the ontological theses in terms of truthmaking, which I argue also fails to generate a substantive dispute. I ultimately argue that the best way to salvage the debate over temporal ontology is to understand it as a debate about the second theses, that is, about whether or not time passes. -/- In Chapter 2, I turn to trying to spell out what temporal passage is supposed to be. I give a typology of the existing accounts of passage in the literature, and give some critique of each. I then try to offer my own account of what passage is: passage is to be identified with change, which is to be understood, not as the standard ‘at-at change’, but in terms of a primitive which I call process. Finally, I note that my account of passage requires relationalism to get off the ground. -/- In Chapter 3, I ask whether we should be substantivalists or relationalists about time, independent of our views on passage. I begin with an overview of the historical debate, focusing heavily on Newton, Leibniz, and the 20th century turn to considering “spacetime” as one entity (rather than treating space and time as two separate entities). I give an overview of the ways in which substantivalism and relationalism are characterized in contemporary debate, and show that it is more difficult than it seems at first pass to parse out what substantivalism is supposed to be. I offer three plausible versions of substantivalism, and characterize relationalism as the denial of all three. I then provide a critical discussion of five major arguments for or against substantivalism, and conclude that there is strong reason to accept relationalism. -/- In Chapter 4, I turn to the question of whether or not we should take our phenomenology as of passage seriously. The dynamic theorist demands an error theory from the static theorist: how is it that we experience temporal passage if there is no such thing? The most common static theorist response to the demand is to say that our experiences as of passage should be considered illusory, either as a cognitive-perceptual illusion akin to illusions of apparent motion, or as a consequence of our (false) view of ourselves as enduring selves against a changing background. I show that these accounts fail because they end up presupposing dynamicity in their quest to show that reality is static, because illusions require dynamicity to get off the ground. I then turn to another common static theorist response to the demand, which is to argue that the phenomenal reality of passage cannot (or should not) tell us anything about the physical reality of passage. One version of this move appeals to the absence of temporal passage in the formulations of the laws of physics; I show that this reasoning relies on an incorrect identification of passage with a privileged property of presentness. Another version argues that because our phenomenology is notoriously subject to a variety of interfering conditions, it is unreliable as a basis for theorizing. I respond that we do not require complete reliability from our evidence in order to use it to build a view, either in science or in philosophy. I conclude that we must take our phenomenology seriously after all, and that it gives us good reason for thinking that temporal passage is a real feature of the world. -/- In Chapter 5, I summarize the work I have done and try to tie up some loose ends by exploring consequences for ontology in light of the process view. I finish with a discussion of what we should do when science and philosophy seem to conflict. (shrink)

This chapter offers a new criticism of the Mind argument that is both decisive and instructive. It introduces a plausible principle (γ) that places a requirement on one’s having a choice about an event whose causal history includes only other events. Depending on γ’s truth-value, the Mind argument fails in such a way that one or the other of the two main species of libertarianism is the best approach to the metaphysics of freedom. Libertarians argue the compatibility of freedom and (...) indeterminism, and their biggest obstacle is the Mind argument that argues an incompatibility between the two. The chapter aims to build a case for the truth of γ, and so for nonreductive libertarianism. This is achieved by defending it from the best objections that have been brought to light, thereby emphasizing γ’s prima facie plausibility. (shrink)

“What is the structure of thought?” is as central a question as any in cognitive science. A classic answer to this question has appealed to a Language of Thought (LoT). We point to emerging research from disparate branches of the field that supports the LoT hypothesis, but also uncovers diversity in LoTs across cognitive systems, stages of development, and species. Our letter formulates open research questions for cognitive science concerning the varieties of rules and representations that underwrite various LoT-based systems (...) and how these variations can help researchers taxonomize cognitive systems.

Initial responses to questionnaires used to assess participants' understanding of informed consent for malaria vaccine trials conducted in the United States and Mali were tallied. Total scores were analyzed by age, sex, literacy (if known), and location. Ninety-two percent (92%) of answers by United States participants and 85% of answers by Malian participants were correct. Questions more likely to be answered incorrectly in Mali related to risk, and to the type of vaccine. For adult participants, independent predictors of higher scores (...) were younger age and female sex in the United States, and male sex in Mali. Scores in the United States were higher than in Mali (P = 0.005). Despite this difference participants at both sites were well informed overall. Although interpretation must be qualified because questionnaires were not intended as research tools and were not standardized among sites, these results do not support concerns about systematic low understanding among research participants in developing versus developed countries.

Logicism is the thesis that all or, at least parts, of mathematics is reducible to deductive logic in at least two senses: (A) that mathematical lexis can be defined by sole recourse to logical constants [a definition thesis]; and, (B) that mathematical theorems are derivable from solely logical axioms [a derivation thesis]. The principal proponents of this thesis are: Frege, Dedekind, and Russell. The central question that I raise in this paper is the following: ‘How did Russell construe the philosophical (...) worth of logicism?’ The argument that I build in response to this is that Russell perceived an inverse proportion between a logical reduction of mathematics and the certitude of non-novel mathematical theorems—such that the more we reduce mathematics to logic, the more certain we become of our mathematical theorems; this was portrayed through a presentation of mathematical knowledge as coherent. Therefore, I set out to sketch Russell’s coherence theory and appraise it in relation to the presence discourse: i.e., in relation to logicism and mathematical certainty. (shrink)

It is standardly assumed that there are three — and only three — ways to solve problem of temporary intrinsics: (a) embrace presentism, (b) relativize property possession to times, or (c) accept the doctrine of temporal parts. The first two solutions are favoured by endurantists, whereas the third is the perdurantist solution of choice. In this paper, I argue that there is a further type of solution available to endurantists, one that not only avoids the usual costs, but is structurally (...) identical to the temporal-parts solution preferred by perdurantists. In addition to providing a general characterization of this new type of solution, I discuss certain of its anticipations in the literature on bundle theory, as well as provide a detailed development of it in terms of my own preferred metaphysics of ordinary objects — namely, a distinctive form of substratum theory tracing to Aristotle.

Prior research has demonstrated that antisocial behavior, substance-use disorders, and personality dimensions of aggression and impulsivity are indicators of a highly heritable underlying dimension of risk, labeled externalizing. Other work has shown that individual trait constructs within this psychopathology spectrum are associated with reduced self-monitoring, as reflected by amplitude of the error-related negativity (ERN) brain response. In this study of undergraduate subjects, reduced ERN amplitude was associated with higher scores on a self-report measure of the broad externalizing construct that links (...) these various indicators. In addition, the ERN was associated with a response-locked increase in anterior theta (4–7 Hz) oscillation; like the ERN, this theta response to errors was reduced among high-externalizing individuals. These findings suggest that neurobiologically based deficits in endogenous action monitoring may underlie generalized risk for an array of impulse-control problems. (shrink)

In this article, we propose the Fair Priority Model for COVID-19 vaccine distribution, and emphasize three fundamental values we believe should be considered when distributing a COVID-19 vaccine among countries: Benefiting people and limiting harm, prioritizing the disadvantaged, and equal moral concern for all individuals. The Priority Model addresses these values by focusing on mitigating three types of harms caused by COVID-19: death and permanent organ damage, indirect health consequences, such as health care system strain and stress, as well as (...) economic destruction. It proposes proceeding in three phases: the first addresses premature death, the second long-term health issues and economic harms, and the third aims to contain viral transmission fully and restore pre-pandemic activity. -/- To those who may deem an ethical framework irrelevant because of the belief that many countries will pursue "vaccine nationalism," we argue such a framework still has broad relevance. Reasonable national partiality would permit countries to focus on vaccine distribution within their borders up until the rate of transmission is below 1, at which point there would not be sufficient vaccine-preventable harm to justify retaining a vaccine. When a government reaches the limit of national partiality, it should release vaccines for other countries. -/- We also argue against two other recent proposals. Distributing a vaccine proportional to a country's population mistakenly assumes that equality requires treating differently situated countries identically. Prioritizing countries according to the number of front-line health care workers, the proportion of the population over 65, and the number of people with comorbidities within each country may exacerbate disadvantage and end up giving the vaccine in large part to wealthy nations.

The European project European and Latin American Systems of Ethics Regulation of Biomedical Research Project (EULABOR) has carried out the first comparative analysis of ethics regulation systems for biomedical research in seven countries in Europe and Latin America, evaluating their roles in the protection of human subjects. We developed a conceptual and methodological framework defining ‘ethics regulation system for biomedical research’ as a set of actors, institutions, codes and laws involved in overseeing the ethics of biomedical research on humans. This (...) framework allowed us to develop comprehensive national reports by conducting semi-structured interviews to key informants. These reports were summarised and analysed in a comparative analysis. The study showed that the regulatory framework for clinical research in these countries differ in scope. It showed that despite the different political contexts, actors involved and motivations for creating the regulation, in most of the studied countries it was the government who took the lead in setting up the system. The study also showed that Europe and Latin America are similar regarding national bodies and research ethics committees, but the Brazilian system has strong and noteworthy specificities. (shrink)

This essay explores the role of God’s omnipresence in Newton’s natural philosophy, with special emphasis placed on how God is related to space. Unlike Descartes’ conception, which denies the spatiality of God, or Gassendi and Charleton’s view, which regards God as completely whole in every part of space, it is argued that Newton accepts spatial extension as a basic aspect of God’s omnipresence. The historical background to Newton’s spatial ontology assumes a large part of our investigation, but with attention also (...) focused on the details of Newton’s unique approach to these traditional Scholastic conceptions.

Purpose Prescription stimulant use as “cognitive enhancers” has been described among undergraduate college students. However, the use of prescription stimulants among future health care professionals is not well characterized. This study was designed to determine the prevalence of prescription stimulant misuse among students at an academic health sciences center. -/- Method Electronic surveys were e-mailed to 621 medical, pharmacy, and respiratory therapy students at East Tennessee State University for four consecutive weeks in fall 2011. Completing the survey was voluntary and (...) anonymous. Surveys asked about reasons for, frequency of, and side effects of nonprescription misuse of prescription stimulants. Given the sensitive material, an opportunity to win one of ten $50 gift cards was used as an incentive. -/- Results Three hundred seventy-two (59.9%) students completed the survey from three disciplines (47.6% medical, 70.5% pharmacy, and 57.6% respiratory therapy). Overall, 11.3% of responders admitted to misusing prescription stimulants. There was more misuse by respiratory therapy students, although this was not statistically significant (10.9% medicine, 9.7% pharmacy, 26.3% respiratory therapy; P = .087). Reasons for prescription stimulant misuse included to enhance alertness/ energy (65.9%), to improve academic performance (56.7%), to experiment (18.2%), and to use recreationally/get high (4.5%). -/- Conclusions Prescription stimulant misuse was prevalent among participating students, but further research is needed to describe prevalence among future health care workers more generally. The implications and consequences of such misuse require further study across professions with emphasis on investigating issues of academic dishonesty (e.g., “cognitive enhancement”), educational quality, and patient safety or health care quality.

Precision Medicine is driven by the idea that the rapidly increasing range of relatively cheap and efficient self-tracking devices make it feasible to collect multiple kinds of phenotypic data. Advocates of N = 1 research emphasize the countless opportunities personal data provide for optimizing individual health. At the same time, using biomarker data for lifestyle interventions has shown to entail complex challenges. In this paper, we argue that researchers in the field of precision medicine need to address the performative dimension (...) of collecting data. We propose the fun-house mirror as a metaphor for the use of personal health data; each health data source yields a particular type of image that can be regarded as a ‘data mirror’ that is by definition specific and skewed. This requires competence on the part of individuals to adequately interpret the images thus provided. (shrink)

The task of this chapter is to investigate and assess Grossmann’s view of the ontological status of categories. It has two dimensions. Because Grossmann does not offer a full discussion of the ontology of categories, we first need to present an interpretation of his view. Our point of departure is Grossmann’s claim that a category is a fundamental property of being (which implies that he holds view 3 above). Our second task is to assess the adequacy of his view. We (...) do this by raising some problems with Grossmann’s account, offering as an alternative view a version of 4 above, and defending it against what we construe as Grossmann’s possible counter-arguments. We argue that the best way to view categories themselves is as ontologically neutral insofar as this opens the way for particular categories to be linguistic entities, mental acts, or properties of extra-mental things. This requires, in turn, a qualified defense of two views rejected by Grossmann—common natures and modes of being. (shrink)

In a reflective and richly entertaining piece from 1979, Doug Hofstadter playfully imagined a conversation between ‘Achilles’ and an anthill (the eponymous ‘Aunt Hillary’), in which he famously explored many ideas and themes related to cognition and consciousness. For Hofstadter, the anthill is able to carry on a conversation because the ants that compose it play roughly the same role that neurons play in human languaging; unfortunately, Hofstadter’s work is notably short on detail suggesting how this magic might be achieved1. (...) Conversely in this paper - finally reifying Hofstadter’s imagination - we demonstrate how populations of simple ant-like creatures can be organised to solve complex problems; problems that involve the use of forward planning and strategy. Specifically we will demonstrate that populations of such creatures can be configured to play a strategically strong - though tactically weak - game of HeX (a complex strategic game).We subsequently demonstrate how tactical play can be improved by introducing a form of forward planning instantiated via multiple populations of agents; a technique that can be compared to the dynamics of interacting populations of social insects via the concept of meta-population. In this way although, pace Hofstadter, we do not establish that a meta-population of ants could actually hold a conversation with Achilles, we do successfully introduce Aunt Hillary to the complex, seductive charms of HeX.

Various approaches have emerged over the last several decades to meet the challenges and complexities of anticipating and responding to the potential impacts of emerging technologies. Although many of the existing approaches share similarities, they each have shortfalls. This paper takes as the object of its study Anticipatory Ethics for Emerging Technologies (ATE) to technology assessment, given that it was formatted to address many of the privations characterising parallel approaches. The ATE approach, also in practice, presents certain areas for retooling, (...) such as how it characterises levels and objects of analysis. This paper results from the work done with the TechEthos Horizon 2020 project in evaluating the ethical, legal, and social impacts of climate engineering, digital extended reality, and neurotechnologies.

Understanding everyday behavior relies heavily upon understanding our ability to improvise, how we are able to continuously anticipate and adapt in order to coordinate with our environment and others. Here we consider the ability of musicians to improvise, where they must spontaneously coordinate their actions with co-performers in order to produce novel musical expressions. Investigations of this behavior have traditionally focused on describing the organization of cognitive structures. The focus, here, however, is on the ability of the time-evolving patterns of (...) inter-musician movement coordination as revealed by the mathematical tools of complex dynamical systems to provide a new understanding of what potentiates the novelty of spontaneous musical action. We demonstrate this approach through the application of cross wavelet spectral analysis, which isolates the strength and patterning of the behavioral coordination that occurs between improvising musicians across a range of nested time-scales. Revealing the sophistication of the previously unexplored dynamics of movement coordination between improvising musicians is an important step towards understanding how creative musical expressions emerge from the spontaneous coordination of multiple musical bodies.

We present experimental evidence that an interpretation was accurate. Current wisdom notwithstanding, we could interpret from the text alone because its information is redundant: repetition provides internal checks. Knowing neither dreamer nor their associations we made falsifiable predictions that we tested by subsequently gathering information about the dreamer. Predictions were supported. Results were repeated with seven additional dreams. Each dream was tightly crafted, used humor, drama or hyperbole to penetrate the dreamer’s defenses, and furthered the emergence of personality. Our experiment (...) compliments fMRI and statistics because it studies a whole text as a unique narrative: one iteration identified healing steps during therapy; another confirmed the psychological meaning of a myth. Our experiment might generate a body of objective knowledge about interpretation and make interpretation itself more accurate. In the US 20% live with mental illness.

Vaccination complacency occurs when perceived risks of vaccine-preventable diseases are sufficiently low so that vaccination is no longer perceived as a necessary precaution.

Searle claims that his theory of institutional reality is particularly suitable as a theoretical scheme of individuation for work in the social sciences. We argue that this is not the case. The first problem with regulatory individuation is due to the familiar fact that institutional judgments have constrained revisability criteria. The second problem with regulatory individuation is due to the fact that institutions amend their declarative judgments based on the inferential (syntactic) properties of the judgments and in response to regulatory (...) pressure, and not based on descriptive (semantic) properties and in response to matters of descriptive adequacy. These two problems imply that ‘regulatory kinds' (countries, borders, kings) will almost inevitably be disjunctive kinds that are ill-suited for scientific theorizing. This also explains why the law often makes odd pronouncements, e.g. calling ketchup a vegetable, considering an arm bent fifteen degrees to be straight, and not admitting that Somaliland is a country.

This record is another iteration of an experiment that will be described more fully in the paper The Dream of the Six-Legged Dog: An Experimental System to Test Meaning, soon to be published. This iteration repeats and confirms the evidence given in that paper. AUDIO RECORD OF CLASS AVAILABLE: link is on first page of the paper you download from this page. (shrink)

In an online, participatory class, we interpreted 'The Dream of Geese Nesting in Trees' knowing nothing of the dreamer beyond age and gender, and having none of the dreamer’s associations. Our interpretation included predictions about the dreamer. When it was complete, we asked the bringer of the dream (who had until then been mostly silent and who also gave no visual feedback to our discussion) to give us more information about the dreamer. Our main predictions were confirmed. Goslings are falling (...) on the dreamer’s head. This record is another iteration of an experiment that will be described more fully in the paper, 'The Dream of the Six-Legged Dog: An Experimental System that Tests Meaning,' soon to be published. This iteration repeats and confirms the evidence given in that paper. AUDIO RECORD OF COMPLETE CLASS: link is at top of paper you can download from this page. (shrink)
