Sensory substitution devices (SSDs) aim to compensate for the loss of a sensory modality, typically vision, by converting information from the lost modality into stimuli in a remaining modality. “The vOICe” is a visual-to-auditory SSD which encodes images taken by a camera worn by the user into “soundscapes” such that experienced users can extract information about their surroundings. Here we investigated how much detail was resolvable during the early induction stages by testing the acuity of blindfolded sighted, naïve vOICe users. (...) Initial performance was well above chance. Participants who took the test twice as a form of minimal training showed a marked improvement on the second test. Acuity was slightly but not significantly impaired when participants wore a camera and judged letter orientations “live”. A positive correlation was found between participants' musical training and their acuity. The relationship between auditory expertise via musical training and the lack of a relationship with visual imagery, suggests that early use of a SSD draws primarily on the mechanisms of the sensory modality being used rather than the one being substituted. If vision is lost, audition represents the sensory channel of highest bandwidth of those remaining. The level of acuity found here, and the fact it was achieved with very little experience in sensory substitution by naïve users is promising. (shrink)

Having an agreed-upon definition of character education would be useful for both researchers and practitioners in the field. However, even experts in character education disagree on how they would define it. We attempted to achieve greater conceptual clarity on this issue through a prototype analysis in which the features perceived as most central to character education were identified. In Study 1 (N = 77), we asked character education experts to enumerate features of character education. Based on these lists, we identified (...) 30 features. In Study 2 (N = 101), experts assessed which features were central to character education through a categorization task. In Study 3 (N = 166), we assessed the extent of centrality using scalar items. We conclude by offering practical advice for the development of future character education studies and programs rooted in what is deemed central to such programs. (shrink)

For more than 200 years scholars have proceeded on the assumption that there was a controversy (in the sense of an argumentative exchange) between the bishop of Cork and Ross, Peter Browne (c. 1665–1735), and his nowadays more famous contemporary, the bishop of Cloyne, George Berkeley (1685–1753) about what we might call ‘the problem of divine attributes’. This problem concerns one of the most vexing issues for 17th /18th century Irish intellectuals. Simply put, it turns on two interconnected (...) questions, namely (1) an ontological question regarding God’s attributes and (2) a semantical question regarding the proper conception of analogy: -/- (1) Do God’s attributes only differ in degree or also in kind from their human counterparts? -/- (2) Is “analogical attribution” only concerned with the structure or the modus of the attribution? That is, is it a separate mode of speech (apart from the metaphorical and literal) or does it just mean we have to use analogies for our divine attributions? -/- In regard to the first question Berkeley argues the attributes of God and humans only differ in degree but not in kind (Alc. 4.22). Browne, on the other hand, is convinced that human and divine attributes differ in kind: “What Knowledge and Goodness are in the Nature of Man, that some inconceivable but correspondent Perfections are in the Nature of God […] which tho’ totally different in Kind from those Properties in us bearing the same Name” (Procedure, 138). Furthermore, Berkeley rejects the notion that analogical attribution is a separate mode of speech in addition to the literal and the metaphorical. Rather, it is an attribution made in the form of an analogy in which the words can be used literally or metaphorically (Alc. 4.21). By contrast, Browne repeatedly insists analogical attribution is more than just using analogies for attributing something to God. He thinks it is a separate mode of speech that ought to be distinguished from literal and metaphorical language (Procedure, 12, 23–29, 123–46). -/- Hence, there can be no doubt that Browne and Berkeley advance conflicting solutions to the problem of divine attributes. Yet, advancing disagreeing positions is not the same as having a (heated) argumentative exchange, i.e., a controversy. In contrast to the controversy-reading, I will defend the following view: Browne surely felt attacked by Berkeley’s elaborations in Alciphron (1732) and reacted to them in his Divine Analogy (1732/3). However, there was no argumentative exchange because Browne’s Procedure (1728) had virtually no influence on Berkeley when he was writing Alciphron. Furthermore, the available evidence suggests that Berkeley was indifferent to the (elaborate) criticisms of Alciphron found in Browne’s Divine Analogy. Thus, while the two bishops have differing positions and Browne reacted to Berkeley there is no reaction on Berkeley’s part and hence there is no argumentative exchange between the two at all, which is why their differing opinions are best described as such and not as a controversy.

Peter Brown’s influential book "The World of Late Antiquity" has had a formidable impact on ancient historiography. Before it, historians who studied the period leading to the deposition of Romolus Agustulus—the last Roman emperor—in 476 AD considered themselves ‘classicists’ or ‘ancient historians’, while those who studied the subsequent period called themselves medievalists; therefore before Brown’s book the collapse of the Roman Empire remained the watershed date that brought upon the Middle Ages. It is not the task of this essay (...) to trace the history of this conception, but to examine the assertions, merits, and faults of Peter Brown’s book. Brown magnified, or more precisely, outright invented a new epoch: “[a number of elements] converged to produce that very distinctive period in European civilization—the Late Antique world”.

I argue that anarchist ideas for organising human communities could be a useful practical resource for Christian ethics. I demonstrate this firstly by introducing the main theological ideas underlying Maximus the Confessor’s ethics, a theologian respected and important in a number of Christian denominations. I compare practical similarities in the way in which ‘love’ and ‘well-being’ are interpreted as the telos of Maximus and Peter Kropotkin’s ethics respectively. I further highlight these similarities by demonstrating them in action when it (...) comes attitudes towards property. I consequently suggest that there are enough similarities in practical aims, for Kropotkin’s ideas for human organising to be useful to Christian ethicists. (shrink)

Children acquire complex concepts like DOG earlier than simple concepts like BROWN, even though our best neuroscientific theories suggest that learning the former is harder than learning the latter and, thus, should take more time (Werning 2010). This is the Complex- First Paradox. We present a novel solution to the Complex-First Paradox. Our solution builds on a generalization of Xu and Tenenbaum’s (2007) Bayesian model of word learning. By focusing on a rational theory of concept learning, we show that it (...) is easier to infer the meaning of complex concepts than that of simple concepts. (shrink)

Berkeley argues that claims about divine predication (e.g., God is wise or exists) should be understood literally rather than analogically, because like all spirits (i.e., causes), God is intelligible only in terms of the extent of his effects. By focusing on the harmony and order of nature, Berkeley thus unites his view of God with his doctrines of mind, force, grace, and power, and avoids challenges to religious claims that are raised by appeals to analogy. The essay concludes by showing (...) how a letter, supposedly by Berkeley, to Peter Browne ("discovered" in 1969 by Berman and Pittion) is, in fact, by John Jackson (1686-1763), controversial theologian and friend of Samuel Clarke. (shrink)

Historically, many Christians have understood God’s transcendence to imply God’s properties categorically differ from any created properties. For multiple historical figures, a problem arose for religious language: how can one talk of God at all if none of our predicates apply to God? What are we to make of creeds and Biblical passages that seem to predicate creaturely properties, such as goodness and wisdom, of God? Thomas Aquinas offered a solution: God is to be spoken of only through analogy (the (...) doctrine of analogy). Gavin Hyman argues Aquinas’s doctrine of analogy was neglected prior to the early-modern period and the neglect of analogy produced the conception of a god vulnerable to atheistic arguments. Contra Hyman, in this paper, I show early-modern atheism arose in a theological context in which there was an active debate concerning analogy. Peter Browne (1665–1735) and William King (1650–1729) offered two competing conceptions of analogical predication that were debated through the 19th century, with interlocutors such as the freethinker Anthony Collins (1676–1729), theologian/philosopher George Berkeley (1685–1753), and skeptic David Hume (1711–1776). Lastly, I discuss the 18th century debate over theological analogy as part of the background relevant to understanding Hume’s Dialogues Concerning Natural Religion. (shrink)

The link between human nature and human flourishing is undeniable. "A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit" (Matt. 7:18). The ontology of the human person will, therefore, ground the nature of human flourishing and thereby sanctification. Spiritual formation is the area of Christian theology that studies sanctification, the Spirit-guided process whereby disciples of Jesus are formed into the image of Jesus (Rom. 8:28-29; 2 Cor. 3:18; 2 Peter 3:18). Until the nineteenth (...) century, there was an overwhelming consensus among Christian thinkers that some form of mind-body (or soul-body) dualism is true of human beings. Recently, that consensus has eroded, and with it the availability of a shared body of knowledge about spiritual formation. Some Christian physicalists argue that dualism is incompatible with central elements of spiritual formation. Neuroscientist Warren Brown and psychologist Brad Strawn offer the only substantive account of spiritual formation from the view of Christian physicalism and its accompanying objections to dualism. It is on their arguments that this chapter focuses. We argue that Brown and Strawn fail to support their incompatibility thesis. Additionally, we argue that Christian physicalism stands in tension with important philosophical and theological foundations of Christian spiritual formation. In doing so we offer a specific form of dualism, the bodily soul view, and explain how this view illuminates the importance of embodiment, our neurological and social development, and hence the important physical aspects of Christian spiritual formation.

This article is part of a For-Discussion-Section of Methods of Information in Medicine about the paper "Biomedical Informatics: We Are What We Publish", written by Peter L. Elkin, Steven H. Brown, and Graham Wright. It is introduced by an editorial. This article contains the combined commentaries invited to independently comment on the Elkin et al. paper. In subsequent issues the discussion can continue through letters to the editor.

The point of this paper is to reveal a dogma in the ordinary conception of sensory imagination, and to suggest another way forward. The dogma springs from two main sources: a too close comparison of mental imagery to perceptual experience, and a too strong division between mental imagery and the traditional propositional attitudes (such as belief and desire). The result is an unworkable conception of the correctness conditions of sensory imaginings—one lacking any link between the conditions under which an imagining (...) aids human action and inference and the conditions under which it is veridical. The proposed solution is, first, to posit a variety of imaginative attitudes—akin to the traditional propositional attitudes—which have different associated correctness (or satisfaction) conditions. The second part of the solution is to allow for imaginings with “hybrid” contents, in the sense that both mental images and representations with language-like constituent structure contribute to the content of imaginings.

If imagination is subject to the will, in the sense that people choose the content of their own imaginings, how is it that one nevertheless can learn from what one imagines? This chapter argues for a way forward in addressing this perennial puzzle, both with respect to propositional imagination and sensory imagination. Making progress requires looking carefully at the interplay between one’s intentions and various kinds of constraints that may be operative in the generation of imaginings. Lessons are drawn from (...) the existing literature on propositional imagination and from the control theory literature concerning the prediction and comparison mechanisms (or “forward models”) involved in ordinary perception. A more general conclusion is reached that, once we have the tools to understand how some imaginings are both under willful control and helpfully guide action and inference, we will have what we need to understand the cognitive basis of imagination in general.

A realist theory of truth for a class of sentences holds that there are entities in virtue of which these sentences are true or false. We call such entities ‘truthmakers’ and contend that those for a wide range of sentences about the real world are moments (dependent particulars). Since moments are unfamiliar, we provide a definition and a brief philosophical history, anchoring them in our ontology by showing that they are objects of perception. The core of our theory is the (...) account of truthmaking for atomic sentences, in which we expose a pervasive ‘dogma of logical form’, which says that atomic sentences cannot have more than one truthmaker. In contrast to this, we uphold the mutual independence of logical and ontological complexity, and the authors outline formal principles of truthmaking taking account of both kinds of complexity.

It is often argued that higher-level special-science properties cannot be causally efficacious since the lower-level physical properties on which they supervene are doing all the causal work. This claim is usually derived from an exclusion principle stating that if a higher-level property F supervenes on a physical property F* that is causally sufficient for a property G, then F cannot cause G. We employ an account of causation as difference-making to show that the truth or falsity of this principle is (...) a contingent matter and derive necessary and sufficient conditions under which a version of it holds. We argue that one important instance of the principle, far from undermining non-reductive physicalism, actually supports the causal autonomy of certain higher-level properties. (shrink)

Category-based induction is an inferential mechanism that uses knowledge of conceptual relations in order to estimate how likely is for a property to be projected from one category to another. During the last decades, psychologists have identified several features of this mechanism, and they have proposed different formal models of it. In this article; we propose a new mathematical model for category-based induction based on distances on conceptual spaces. We show how this model can predict most of the properties of (...) this kind of reasoning while providing a solid theoretical foundation for it. We also show that it subsumes some of the previous models proposed in the literature and that it generates new predictions. (shrink)

There is a strong appetite in ‘the wild’ (i.e., beyond the academy) for public philosophy. There are myriad forums available, from magazines and online publications to podcasts and YouTube videos, for those who wish to engage in philosophy in a non-academic context. For academic philosophers, this has raised methodological and metaphilosophical questions like: ‘what is the best way to engage in public philosophy?’ and ‘what are our aims when we engage in public philosophy?’ But what do ‘the public’ want? If (...) public philosophy is philosophy written for a public audience, what is it, exactly, that it can or might do for them? Several answers have been proposed by philosophers, but less attention has been paid to how the public themselves might answer that question. The aim of this essay is to try and put together at least the beginning of an answer. In June 2022 we put out a survey in the hope of eliciting views from ‘the public’ on issues relating to the nature and aims of both philosophy (more generally) and public philosophy. In doing so, our aim was to take a ‘democratic’ approach to answering the question: What is public philosophy? (shrink)

We offer a critical assessment of the “exclusion argument” against free will, which may be summarized by the slogan: “My brain made me do it, therefore I couldn't have been free”. While the exclusion argument has received much attention in debates about mental causation (“could my mental states ever cause my actions?”), it is seldom discussed in relation to free will. However, the argument informally underlies many neuroscientific discussions of free will, especially the claim that advances in neuroscience seriously challenge (...) our belief in free will. We introduce two distinct versions of the argument, discuss several unsuccessful responses to it, and then present our preferred response. This involves showing that a key premise – the “exclusion principle” – is false under what we take to be the most natural account of causation in the context of agency: the difference-making account. We finally revisit the debate about neuroscience and free will. (shrink)

Assertions are the centre of gravity in social epistemology. They are the vehicles we use to exchange information within scientific groups and society as a whole. It is therefore essential to determine under which conditions we are permitted to make an assertion. In this paper we argue and provide empirical evidence for the view that the norm of assertion is justified belief: truth or even knowledge are not required. Our results challenge the knowledge account advocated by, e.g. Williamson (1996), in (...) general, and more specifically, put into question several studies conducted by Turri (2013, 2016) that support a knowledge norm of assertion. Instead, the justified belief account championed by, e.g. Douven (2006), seems to prevail. (shrink)

Many theorists claim that inner speech is importantly linked to human metacognition (thinking about one's own thinking). However, their proposals all rely upon unworkable conceptions of the content and structure of inner speech episodes. The core problem is that they require inner speech episodes to have both auditory-phonological contents and propositional/semantic content. Difficulties for the views emerge when we look closely at how such contents might be integrated into one or more states or processes. The result is that, if inner (...) speech is especially valuable to metacognition, we do not currently understand why it is. The article concludes with two positive proposals for understanding the content and structure of inner speech episodes, which should serve as constraints on future accounts of the metacognitive value of inner speech.

In this paper, we outline a comprehensive approach to composed analogies based on the theory of conceptual spaces. Our algorithmic model understands analogy as a search procedure and builds upon the idea that analogical similarity depends on a conceptual phenomena called ‘dimensional salience.’ We distinguish between category-based, property-based, event-based, and part-whole analogies, and propose computationally-oriented methods for explicating them in terms of conceptual spaces.

Delusional beliefs have sometimes been considered as rational inferences from abnormal experiences. We explore this idea in more detail, making the following points. Firstly, the abnormalities of cognition which initially prompt the entertaining of a delusional belief are not always conscious and since we prefer to restrict the term “experience” to consciousness we refer to “abnormal data” rather than “abnormal experience”. Secondly, we argue that in relation to many delusions (we consider eight) one can clearly identify what the abnormal cognitive (...) data are which prompted the delusion and what the neuropsychological impairment is which is responsible for the occurrence of these data; but one can equally clearly point to cases where this impairments is present but delusion is not. So the impairment is not sufficient for delusion to occur. A second cognitive impairment, one which impairs the ability to evaluate beliefs, must also be present. Thirdly (and this is the main thrust of our chapter) we consider in detail what the nature of the inference is that leads from the abnormal data to the belief. This is not deductive inference and it is not inference by enumerative induction; it is abductive inference. We offer a Bayesian account of abductive inference and apply it to the explanation of delusional belief. (shrink)

A popular view has it that the mental representations underlying human pretense are not beliefs, but are “belief-like” in important ways. This view typically posits a distinctive cognitive attitude (a “DCA”) called “imagination” that is taken toward the propositions entertained during pretense, along with correspondingly distinct elements of cognitive architecture. This paper argues that the characteristics of pretense motivating such views of imagination can be explained without positing a DCA, or other cognitive architectural features beyond those regulating normal belief and (...) desire. On the present “Single Attitude” account of imagination, propositional imagining just is a form of believing. The Single Attitude account is also distinguished from “metarepresentational” accounts of pretense, which hold that both pretending and recognizing pretense in others require one to have concepts of mental states. It is argued, to the contrary, that pretending and recognizing pretense require neither a DCA nor possession of mental state concepts. (shrink)

It is widely held that introspection-based self-ascriptions of mental states are immune to error through misidentification , relative to the first person pronoun. Many have taken such errors to be logically impossible, arguing that the immunity holds as an “absolute” necessity. Here I discuss an actual case of craniopagus twins—twins conjoined at the head and brain—as a means to arguing that such errors are logically possible and, for all we know, nomologically possible. An important feature of the example is that (...) it is one where a person may be said to be introspectively aware of a mental state that occurs outside of her own mind. Implications are discussed for views of the relation between introspection and mental state ownership, and between introspection and epistemic criteria for the “mark of the mental.”. (shrink)

YouTube has been implicated in the transformation of users into extremists and conspiracy theorists. The alleged mechanism for this radicalizing process is YouTube’s recommender system, which is optimized to amplify and promote clips that users are likely to watch through to the end. YouTube optimizes for watch-through for economic reasons: people who watch a video through to the end are likely to then watch the next recommended video as well, which means that more advertisements can be served to them. This (...) is a seemingly innocuous design choice, but it has a troubling side-effect. Critics of YouTube have alleged that the recommender system tends to recommend extremist content and conspiracy theories, as such videos are especially likely to capture and keep users’ attention. To date, the problem of radicalization via the YouTube recommender system has been a matter of speculation. The current study represents the first systematic, pre-registered attempt to establish whether and to what extent the recommender system tends to promote such content. We begin by contextualizing our study in the framework of technological seduction. Next, we explain our methodology. After that, we present our results, which are consistent with the radicalization hypothesis. Finally, we discuss our findings, as well as directions for future research and recommendations for users, industry, and policy-makers. (shrink)

Propositions are traditionally regarded as performing vital roles in theories of natural language, logic, and cognition. This chapter offers an opinionated survey of recent literature to assess whether they are still needed to perform three linguistic roles: be the meaning of a declarative sentence in a context, be what is designated by certain linguistic expressions, and be the content of illocutionary acts. After considering many of the relevant choice-points, I suggest that there remains a linguistic basis for propositions, but not (...) for some of the traditional reasons. (shrink)

This chapter examines how epistemic norms could be social norms, with a reliance on work on the philosophy and social science of social norms from Bicchieri (on the one hand) and Brennan, Eriksson, Goodin and Southwood (on the other hand). We explain how the social ontology of social norms can help explain the rationality of epistemic cooperation, and how one might begin to model epistemic games.

Speakers offer testimony. They also hedge. This essay offers an account of how hedging makes a difference to testimony. Two components of testimony are considered: how testimony warrants a hearer's attitude, and how testimony changes a speaker's responsibilities. Starting with a norm-based approach to testimony where hearer's beliefs are prima facie warranted because of social norms and speakers acquire responsibility from these same norms, I argue that hedging alters both components simultaneously. It changes which attitudes a hearer is prima facie (...) warranted in forming in response to testimony, and reduces how much responsibility a speaker undertakes in testifying. A consequence of this account is that speakers who hedge for strategic purposes deprive their hearers of warrant for stronger doxastic attitudes. (shrink)

We trace the difference between the ways in which apes and humans co–operate to differences in communicative abilities, claiming that the pressure for future–directed co–operation was a major force behind the evolution of language. Competitive co–operation concerns goals that are present in the environment and have stable values. It relies on either signalling or joint attention. Future–directed co–operation concerns new goals that lack fixed values. It requires symbolic communication and context–independent representations of means and goals. We analyse these ways of (...) co–operating in game–theoretic terms and submit that the co–operative strategy of games that involve shared representations of future goals may provide new equilibrium solutions.

Sentences like ⌜δ is indescribable⌝ appear to state that the speaker is unable to do what the speaker just did. This is known as the "paradox of ineffability." An explanation for how such sentences can be true is widely thought to be a pre-requisite for showing the coherence of ineffability. This paper offers a dissolution of the paradox. I argue that the relevant sentences are always false. However, I show that the falsity of such sentences does not entail that ineffability (...) is incoherent. That ⌜δ is indescribable⌝ can never be truthfully said does not entail that ineffability cannot be coherently explicated. (shrink)

Epistemic contextualism in the style of Lewis (1996) maintains that ascriptions of knowledge to a subject vary in truth with the alternatives that can be eliminated by the subject’s evidence in a context. Schaffer (2004, 2005, 2007, 2008, 2015), Schaffer and Knobe (2012), and Schaffer and Szabo ́ (2014) hold that the question under discussion or QUD always determines these alternatives in a context. This paper shows that the QUD does not perform such a role for "know" and uses this (...) result to draw a few lessons about the metasemantics of context- sensitivity. (shrink)

We argue that knowledge is not the norm of belief given that ‘I believe’ is used to hedge. We explore the consequences of this argument for the normative relationship between belief and assertion.

I distinguish paradoxes and hypodoxes among the conundrums of time travel. I introduce ‘hypodoxes’ as a term for seemingly consistent conundrums that seem to be related to various paradoxes, as the Truth-teller is related to the Liar. In this article, I briefly compare paradoxes and hypodoxes of time travel with Liar paradoxes and Truth-teller hypodoxes. I also discuss Lewis’ treatment of time travel paradoxes, which I characterise as a Laissez Faire theory of time travel. Time travel paradoxes are impossible according (...) to Laissez Faire theories, while it seems hypodoxes are possible. (shrink)

This chapter addresses the relationship between misinformation and disagreement. We begin by arguing that one traditional bogeyman in this domain, ideological polarization, does not account for the many problems that have been documented. Instead, affective polarization seems to be the root cause of most of these problems. We then discuss the relationships between moral outrage, misinformation, and affective polarization. We next turn to the political implications of affective polarization and conclude by discussing some potential solutions to the problems that arise (...) in this area. (shrink)

Skow ([2007]), and much more recently Callender ([2017]), argue that time can be distinguished from space due to the special role it plays in our laws of nature: our laws determine the behaviour of physical systems across time, but not across space. In this work we assess the claim that the laws of nature might provide the basis for distinguishing time from space. We find that there is an obvious reason to be sceptical of the argument Skow submits for distinguishing (...) time from space: Skow fails to pay sufficient attention to the relationship between the dynamical laws and the antecedent conditions required to establish a complete solution from the laws. Callender’s more sophisticated arguments in favour of distinguishing time from space by virtue of the laws of nature presents a much stronger basis to draw the distinction. By developing a radical reading of Callender’s view we propose a novel approach to differentiating time and space that we call temporal perspectivalism. This is the view according to which the difference between time and space is a function of the agentive perspective. (shrink)

AI systems, like self-driving cars, healthcare robots, or Autonomous Weapon Systems, already play an increasingly important role in our lives and will do so to an even greater extent in the near future. This raises a fundamental philosophical question: who is morally responsible when such systems cause unjustified harm? In the paper, we argue for the admittedly surprising claim that some of these systems can themselves be morally responsible for their conduct in an important and everyday sense of the term—the (...) attributability sense. More specifically, relying on work by Nomy Arpaly and Timothy Schroeder (In Praise of Desire, OUP 2014), we propose that the behavior of these systems can manifest their ‘quality of will’ and thus be regarded as something they can be blameworthy for. We develop this position in detail, justify some of its crucial presuppositions, and defend it against potential objections. (shrink)

The articles in this issue represent the pursuit of a new understanding of the human past, one that can replace the neo-saltationist view of a human revolution with models that can account for the complexities of the archaeological record and of human social lives. The articulation of archaeological, philosophical, and biological perspectives seems to offer a strong foundation for exploring available evidence, and this was the rationale for collecting these particular articles. Even at this preliminary stage there is a coherence (...) emerging in proposals: the origin and operation of symbolically rich, complexly signaling human social systems was the consequence of the long-term evolution of multiple components of perceiving and negotiating social interactions, a contingent outcome of myriad adaptive shifts rather than a single event.

Visual imagination (or visualization) is peculiar in being both free, in that what we imagine is up to us, and useful to a wide variety of practical reasoning tasks. How can we rely upon our visualizations in practical reasoning if what we imagine is subject to our whims? The key to answering this puzzle, I argue, is to provide an account of what constrains the sequence in which the representations featured in visualization unfold—an account that is consistent with its freedom. (...) Three different proposals are outlined, building on theories that link visualization to sensorimotor predictive mechanisms (e.g., efference copies, forward models ). Each sees visualization as a kind of reasoning, where its freedom consists in our ability to choose the topic of the reasoning. Of the three options, I argue that the approach many will find most attractive—that visualization is a kind of off-line perception, and is therefore in some sense misrepresentational—should be rejected. The two remaining proposals both conceive of visualization as a form of sensorimotor reasoning that is constitutive of one’s commitments concerning the way certain kinds of visuomotor scenarios unfold. According to the first, these commitments impinge on one’s web of belief from without, in the manner of normal perceptual experience; according to the second, these commitments just are one’s (occurrent) beliefs about such generalizations. I conclude that, despite being initially counterintuitive, the view of visualization as a kind of occurrent belief is the most promising. (shrink)

Epistemic terms of various syntactic categories can uniformly be used to do the same thing—to hedge. This essay clarifies hedging as a phenomenon and explains how hedging happens by advancing the positional theory. The guiding idea is that, in uttering declaratives, speakers signal what their epistemic position is towards the content put into play by the declarative. The default signal is that the speaker knows. But when an epistemic term hedges, the term overrides the default. The non-default signal sent is (...) that the speaker or someone else occupies the position indicated by the term. To make that idea precise, the positional theory treats hedging as a discourse function. Terms hedge because of how a declarative containing an epistemic term is situated within a discourse.

Philosophy in the West divides into three parts: Analytic Philosophy (AP), Continental Philosophy (CP), and History of Philosophy (HP). But all three parts are in a bad way. AP is sceptical about the claim that philosophy can be a science, and hence is uninterested in the real world. CP is never pursued in a properly theoretical way, and its practice is tailor-made for particular political and ethical conclusions. HP is mostly developed on a regionalist basis: what is studied is determined (...) by the nation or culture to which a philosopher belongs, rather than by the objective value of that philosopher’s work. Progress in philosophy can only be attained by avoiding these pitfalls. (shrink)

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.

PURPOSE—A substantial fraction of the observations made by clinicians and entered into patient records are expressed by means of negation or by using terms which contain negative qualifiers (as in “absence of pulse” or “surgical procedure not performed”). This seems at first sight to present problems for ontologies, terminologies and data repositories that adhere to a realist view and thus reject any reference to putative non-existing entities. Basic Formal Ontology (BFO) and Referent Tracking (RT) are examples of such paradigms. The (...) purpose of the research here described was to test a proposal to capture negative findings in electronic health record systems based on BFO and RT. METHODS—We analysed a series of negative findings encountered in 748 sentences taken from 41 patient charts. We classified the phenomena described in terms of the various top-level categories and relations defined in BFO, taking into account the role of negation in the corresponding descriptions. We also studied terms from SNOMED-CT containing one or other form of negation. We then explored ways to represent the described phenomena by means of the types of representational units available to realist ontologies such as BFO. RESULTS—We introduced a new family of ‘lacks’ relations into the OBO Relation Ontology. The relation lacks_part, for example, defined in terms of the positive relation part_of, holds between a particular p and a universal U when p has no instance of U as part. Since p and U both exist, assertions involving ‘lacks_part’ and its cognates meet the requirements of positivity. CONCLUSION—By expanding the OBO Relation Ontology, we were able to accommodate nearly all occurrences of negative findings in the sample studied. (shrink)

Our aim in this paper is to suggest that most current theories of global justice fail to adequately recognise the importance of global public goods. Broadly speaking, this failing can be attributed at least in part to the complexity of the global context, the individualistic focus of most theories of justice, and the localised nature of the theoretical foundations of most theories of global justice. We argue ? using examples (particularly that of protecting antibiotic efficacy) ? that any truly effective (...) theory of global justice must recognise the importance of global public goods. Global public goods confer significant benefits to individuals yet can only be effectively promoted and preserved through collective action and the restriction of individual choice; something which most theories of justice are structurally unequipped to sufficiently promote.

Hoerl & McCormack claim that animals don't represent time. Because this makes a mystery of established findings in comparative psychology, there had better be some important payoff. The main one they mention is that it explains a clash of intuition about the reality of time's passage. But any theory that recognizes the representational requirements of agency can do likewise.

This paper discusses the finite version of the two envelope paradox. (That is, we treat the paradox against the background assumption that there is only a finite amount of money in the world.).

Erwin Schrödinger holds a prominent place in the history of science primarily due to his crucial role in the development of quantum physics. What is perhaps lesser known are his insights into subject-object duality, consciousness and mind. He documented himself that these were influenced by the Upanishads, a collection of ancient Hindu spiritual texts. Central to his thoughts in this area is that Mind is only One and there is no separation between subject and object. This chapter aims to bridge (...) Schrödinger’s view on One Mind with the teachings of Dōgen, a twelfth century Zen master. This bridge is formed by addressing the question of how time relates to One Mind, and subject-object duality. Schrödinger describes the experience of One Mind to be like a timeless now, whereas subject-object duality involves a linear continuum of time. We show how these differing positions are unified in the notion of ‘absolute present’, which was put forward in the philosophy of Nishida Kitarō (1871–1945). In addition, we argue that it is in this notion of absolute present that the views of Schrödinger, Dōgen and Nishida meet. (shrink)
