Peer review is a widely accepted instrument for raising the quality of science. Peer review limits the enormous unstructured influx of information and the sheer amount of dubious data, which in its absence would plunge science into chaos. In particular, peer review offers the benefit of eliminating papers that suffer from poor craftsmanship or methodological shortcomings, especially in the experimental sciences. However, we believe that peer review is not always appropriate for the evaluation of controversial hypothetical science. We argue that (...) the process of peer review can be prone to bias towards ideas that affirm the prior convictions of reviewers and against innovation and radical new ideas. Innovative hypotheses are thus highly vulnerable to being “filtered out” or made to accord with conventional wisdom by the peer review process. Consequently, having introduced peer review, the Elsevier journal Medical Hypotheses may be unable to continue its tradition as a radical journal allowing discussion of improbable or unconventional ideas. Hence we conclude by asking the publisher to consider re-introducing the system of editorial review to Medical Hypotheses. (shrink)

Why do so many of God’s followers seem to prefer their boxed-in religion over God? Listen to their rhetoric and you might wonder how a Supreme Being could be so narrow and small, so angry and unattractive. It’s time to start over with an honest conversation instead of a box. If God does exist, there should be some clear indications of his being. And if humans bear God’s image, as the Bible indicates, then we should be able to connect with (...) God on some level. This book is about God, not religion. It’s about questions more than watertight answers. It’s about the experience of God more than it is about incontrovertible evidence that he exists. God can’t be seen, but he can be found. And while he can’t be fully explained, he can be known and experienced. Religious boxes have a way of blinding us to spiritual reality. So this dialogue is all God, no box. Are you ready? (shrink)

In this paper, I reinterpret the conflict between rewilders and those who want to preserve traditional agricultural landscapes. By showing that underlying both positions is a common outlook in which nature preservation can be described as a primarily interpretative act geared towards the preservation of meaning by establishing a successful contact with external reality, I hope to refocus the debate away from the current stalemate. Too often, the debate ends in a dispute about what counts as 'real nature'. By interpreting (...) nature preservation - whether it is directed at rewilding or at preserving old agricultural landscapes - as an act that is a response to nature's meanings, we will refocus attention on the real issue underlying preservation: articulating the ways nature is meaningful to us.

Responses to the COVID-19 pandemic prompted people and institutions to turn to online virtual environments for a wide variety of social gatherings. In this perspectives article, we draw upon our previous work and interviews with Ghanaian Christian leaders to consider implications of this shift. Specifically, we propose that the shift from physical to virtual interactions mimics and amplifies the neoliberal individualist experience of abstraction from place associated with Eurocentric modernity. On the positive side, the shift from physical to virtual environments (...) liberates people to selectively pursue the most fulfilling interactions, free from constraints of physical distance. On the negative side, the move from physical to virtual space necessitates a shift from material care and tangible engagement with the local community to the psychologization of care and pursuit of emotional intimacy in relations of one’s choosing—a dynamic that further marginalizes people who are already on the margins. The disruptions of the pandemic provide an opportunity to re-set social relations, to design ways of being that better promote sustainable collective well-being rather than fleeting personal fulfillment.

When we are fatigued, we feel that our performance is worse than when we are fresh. Yet, for over 100 years, researchers have been unable to identify an objective, behavioral measure that covaries with the subjective experience of fatigue. Previous work suggests that the metrics of signal detection theory —response bias and perceptual certainty —may change as a function of fatigue, but no work has yet been done to examine whether these metrics covary with fatigue. Here, we investigated cognitive fatigue (...) using SDT. We induced fatigue through repetitive performance of the n-back working memory task, while functional magnetic resonance imaging data was acquired. We also assessed cognitive fatigue at intervals throughout. This enabled us to assess not only whether criterion and d’ covary with cognitive fatigue but also whether similar patterns of brain activation underlie cognitive fatigue and SDT measures. Our results show that both criterion and d’ were correlated with changes in cognitive fatigue: as fatigue increased, subjects became more conservative in their response bias and their perceptual certainty declined. Furthermore, activation in the striatum of the basal ganglia was also related to cognitive fatigue, criterion, and d’. These results suggest that SDT measures represent an objective measure of cognitive fatigue. Additionally, the overlap and difference in the fMRI results between cognitive fatigue and SDT measures indicate that these measures are related while also separate. In sum, we show the relevance of SDT measures in the understanding of fatigue, thus providing researchers with a new set of tools with which to better understand the nature and consequences of cognitive fatigue.

I offer a new metacognitive account of the feeling of agency over bodily actions. On this model the feeling of agency is the metacognitive monitoring of two cues: i) smoothness of action: done via monitoring the output of the comparison between actual and predicted sensory consequences of action and ii) action outcome: done via monitoring the outcome of action and its success relative to a prior intention. Previous research has shown that the comparator model offers a powerful explanation of the (...) feeling of agency. However, within the literature there is a growing sense of unease with the model; a consensus seems to be building that the model is not up to the task of explaining all of the new discoveries made regarding the feeling of agency since its inception. Most problematically there are paradigms which deeply challenge the comparator model by suggesting that a weak feeling of agency can be elicited even when no motor prediction is formed. The new account offered here inherits the explanatory power of the comparator model whilst avoiding this problem. (shrink)

Introduction. The sense of agency over thoughts is the experience of oneself qua agent of mental action. Those suffering certain psychotic symptoms are thought to have a deficient sense of agency. Here I seek to explain this sense of agency in terms of metacognition. Method. I start with the proposal that the sense of agency is elicited by metacognitive monitoring representations that are used in the intentional inhibition of thoughts. I apply this model to verbal hallucinations and the like and (...) examine the plausibility of this model explaining deficits associated with these symptoms. Results. By tying the sense of agency to metacognitive inhibition I propose that the loss of a sense of agency in certain psychotic symptoms is accompanied by a particular deficit in the patient’s ability to control their own thinking. This is consistent with the experiences of those at high risk of developing hallucinations, who report more intrusive thoughts than controls. The model I present is able to explain why those at risk of developing verbal hallucinations and those suffering from verbal hallucinations have deficits in the intentional inhibition of thought. I defend this account from a possible objection by distinguishing the form of the intentional inhibition deficit displayed by those suffering verbal hallucination from that displayed by those suffering from orbital-frontal cortex lesions and posttraumatic stress disorder. Conclusion. A plausible hypothesis is that the sense of agency over thoughts is elicited by the metacognitive monitoring representation used to intentionally inhibit. (shrink)

Taking his critique of totalitarianizing conceptions of community as a starting point, this text examines Jean-Luc Nancy's work of an ‘ontology of plural singular being’ for its political implications. It argues that while at first this ontology seems to advocate a negative or an anti-politics only, it can also be read as a ‘theory of communicative praxis’ that suggests a certain ethos – in the form of a certain use of symbols (which is expressed only inaptly by the word ‘style’) (...) that would render the ontological plurality of singulars perceptible and practically effective. Finally, some recent texts by Nancy even sidestep the ontology of being-with and face the question of what politics, faced with demands of justice, could be and what a democratic politics could provide. Both of these aspects in Nancy's work, however, still remain to be spelled out more politically. (shrink)

The rubber hand illusion (RHI) is the experience of an artificial body part as being a real body part and the experience of touch coming from that artificial body part. An explanation of this illusion would take significant steps towards explaining the experience of embodiment in one’s own body. I present a new cognitive model to explain the RHI. I argue that the sense of embodiment arises when an on-line representation of the candidate body part is represented as matching an (...) off-line prototype representation of what one’s body is usually like. The cause of the sense of embodiment in the model body part only partially overlaps with the causes of proprioceptive drift, which commonly accompanies the RHI, and so is compatible with observed dissociations between the illusion and proprioceptive drift. The distinguishing features of this model are the off-line body representation, and the process of matching an on-line model to an off-line model, both of which are to be understood in terms of a conceptual space. -/- Key Words: Rubber Hand Illusion; RHI; Sense of Embodiment; Self Consciousness; Body Experience.

An account of the conflict between our positive and negative emotional relationships to the Earth and how they will be resolved for the Symbiocene, the next period in the history of the Earth.

I compare Frith and colleagues’ influential comparator account of how the sense of agency is elicited to the multifactorial weighting model advocated by Synofzik and colleagues. I defend the comparator model from the common objection that the actual sensory consequences of action are not needed to elicit the sense of agency. I examine the comparator model’s ability to explain the performance of healthy subjects and those suffering from delusions of alien control on various self-attribution tasks. It transpires that the comparator (...) model needs case-by-case adjustment to deal with problematic data. In response to this, the multifactorial weighting model of Synofzik and colleagues is introduced. Although this model is incomplete, it is more naturally constrained by the cases that are problematic for the comparator model. However, this model may be untestable. I conclude that currently the comparator model approach has stronger support than the multifactorial weighting model approach. (shrink)

In this paper, I defend a pluralistic view of phenomenological method which will provide evidence for particular accounts of experience without relying exclusively on the reflective method or on intuition as a criterion for truth. To this end, I discuss the prospects for indirect phenomenology. I argue that phenomenology ought to be defined by its object of investigation, first-person experience, and not by any particular method of gaining access to this object of investigation. On this view, an integration of naturalized (...) phenomenology into the cognitive sciences is far more feasible than we might have expected. (shrink)

The advance of the internet and social media has had a drastic impact on our epistemic environment. This paper will focus on two different risks epistemic agents face online: being exposed to fake news and epistemic flooding. While the first risk is widely known and has been extensively discussed in the philosophical literature, the notion of ‘epistemic flooding’ is a novel concept introduced in this paper. Epistemic flooding occurs when epistemic agents find themselves in epistemic environments in which they are (...) routinely confronted with more information and evidence than they can diligently process. Epistemic flooding is one of the most significant risks epistemic agents run while using social media and one of the reasons why the first risk (being exposed to fake news) is especially pernicious. It is particularly harmful if one ascribes to the Spinozan model of belief acquisition in which belief comes easy. Mitigating the combined threat of fake news and epistemic flooding requires us to think normatively about our epistemic environments and how to better them. This paper turns to the normative framework of epistemic environmentalism in order to accomplish this. (shrink)

This article examines the argument that biodiversity is crucial for well-functioning ecosystems and that such ecosystems provide important goods and services to our human societies, in short the ecosystem services argument (ESA). While the ESA can be a powerful argument for nature preservation, we argue that its dominant functionalist interpretation is confronted with three significant problems. First, the ESA seems unable to preserve the nature it claims to preserve. Second, the ESA cannot explain why those caring about nature want to (...) preserve it. Third, the ESA might undermine its own goal because it potentially decreases environmental motivations. (shrink)

The sense of agency over bodily actions is the feeling that one is the agent of one's actions. In this paper I examine the prospects of Frith and colleagues' influential comparator account of how the sense of agency over one's bodily actions is elicited, in comparison to the multifactorial weighting model advocated by Synofzik and colleagues in response to some problems with this account. I examine two problems for the comparator model. I consider the common objection that the actual sensory (...) consequences of action aren't needed to elicit the sense of agency with a look at the data which most strongly suggests this, namely the preserved sense of agency over phantom limb movements. I consider a problem for the comparator model in the behaviour of normal subjects placed in unusual circumstances, in particular I consider the 'wheel of fortune' studies which some take to be problematic for the comparator model. I argue that neither of these objections are devastating for the comparator model and that the comparator model plus some plausible assumptions can explain these data. However, these assumptions are not part of the original comparator model. In the end we get a version of the comparator model modified to deal with problematic cases in a manner that could be seen as somewhat ad hoc. To deal with this the multifactorial weighting model of Synofzik and colleagues is introduced. Although this model is incomplete a single version can be offered which is naturally constrained by the cases which are problematic for the comparator model. However, it is not clear what, if anything, could count as evidence against the multifactorial weighting model. Despite being generated with the data in mind it may be untestable. I conclude that currently the comparator model has stronger support than the multifactorial weighting model. (shrink)

Since the publication of Between Facts and Norms, Habermas’s concept of communicative power has been the topic of significant discussion. This article contributes to this conversation by examining Habermas’s account of what makes communication powerful. I argue that Habermas’s conception of communicative power describes a nonviolent and noninstrumental mode of acting and being with others in language. This mode of engagement underwrites a conception of power that is structurally different from willing, one that builds meaningful worlds and (trans-)forms those engaging (...) in communicative procedures. In drawing out this aspect of Habermas’s conception, I show that he is not a rationalist and proceduralist whose account of communicative procedures protects decision-making from irrational aesthetic powers. Rather, he presents communication as a mimetic achievement, a set of aesthetic practices and experiences that affectively alter its participants. With this position, Habermas makes an important contribution to and not just against the analysis of the aesthetic dimensions of political life. In casting communication as a mimetic achievement, Habermas presents an account of how communication opens worlds and forms subjects. Yet since these aspects of communication arrive in linguistic form, he can also examine affective and aesthetic experiences within discursive procedures. We can understand world-opening and aesthetic (trans-)formation as an essential part of democratic politics while also identifying the perspectives and resources by which actors can reflect on and critically evaluate whether an opinion is justified or whether a political project is worth pursuing.

In spite of his reputations as an impractical skeptic or dogmatic idealist, Plato’s Socrates is often an impressive example of a critical thinker, and we can use Plato’s dialogues to promote such skills in the college classroom. This essay summarizes recent institutional motivations for promoting critical thinking in a student-centered, active-learning pedagogy; compares Plato’s core model of education and fundamental rationale for it; shares an essay–presentation–discussion assignment that serves those modern and ancient goals; and discusses how this flexible type of (...) assignment is especially well suited for Plato’s dialogues, serving students and teachers in a Socratic manner. The first two sections thus situate Plato’s dialogues in relation to the heart of critical thinking in higher education generally. The later sections and Appendix explain a way to “follow the arguments” with Socrates that’s informed both by recent best practices and by much of what we see in Plato’s dialogues. (shrink)

Conceived as a solution to clinical dilemmas, and now required by organizations for hospital accreditation, ethics committees have been subject only to small-scale studies. The wide use of ethics committees and the diverse roles they play compel study. In 1999 the University of Pennsylvania Ethics Committee Research Group (ECRG) completed the first national survey of the presence, composition, and activities of U.S. healthcare ethics committees (HECs). Ethics committees are relatively young, on average seven years in operation. Eighty-six percent of ethics (...) committees report that they play a role in ongoing clinical decision making through clinical ethics consultation. All are engaged in developing institutional clinical policy. Although 4.5% of HECs write policy on managed care, 50% of HEC chairs feel inadequately prepared to address managed care. The power and activity of ethics committees parallels the composition of those committees and the relationship of members to their institutions. The role of ethics committees across the nation in making policies about clinical care is greater than was known, and ethics committees will likely continue to play an important role in the debate and resolution of clinical cases and clinical policies.

“Spousal revenge” killers murder their child apparently out of a desire to cause harm to their ex-partner, the child’s other parent. Standard explanations of these killings fail to provide an adequate solution to what I call the problem of spousal revenge filicide. This is the problem of how a killer comes to take their rage at their former partner out on their own child and how that child can be dehumanized to the point of murder. Although the dehumanization of the (...) victim is acknowledged to occur, why it occurs is not well understood. Here, I offer an hypothesis that the killer fails to represent their child as a moral subject with a mind of their own. This is due to a deficit in the killer’s capacity for person perception which is, by hypothesis, pathological. As such, the killer experiences the child as an object, rather than a person, which is of significant emotional value to the other parent. The specificity of this disorder explains why the ex-partner themselves is not targeted, and it explains how the killer is able to understand that killing the child will harm the other parent.

Objective To review the way consciousness is operationalised in contemporary research, discuss strengths and weaknesses of current approaches and propose new measures. Method We first reviewed the literature pertaining to the phenomenal character of visual and self-consciousness as well as awareness of visual stimuli. We also reviewed more problematic cases of dreams and animal consciousness, specifically that of octopuses. Results Despite controversies, work in visual and self consciousness is highly developed and there are notable successes. Cases where experiences are not (...) induced, such as dreams, and where no verbal report is possible, such as when we study purported experiences of octopuses, are more challenging. It is difficult to be confident about the reliability and validity of operationalisations of dreams. Although this is a general concern about the measuring consciousness, it is not a sufficiently severe concern to completely undermine the work reviewed on vision and self-consciousness. It is more difficult to see how the good work on human psychology can be applied to non-human animals, especially those with radically different nervous systems, such as octopuses. Given the limitations of report-based operationalisations of consciousness, it is desirable to develop non-report-based measures, particularly for phenomenal qualities. We examine a number of possibilities and offer two possible approaches of varying degrees of practicality, the first based on combining quality space descriptions of phenomenal qualities and the notion of a “neural activation space” inherited from connectionist A.I., the second being a novel match to target approach Conclusion Consciousness is a multifacted phenomenon and requires a variety of operationalisations to be studied.

The sense of embodiment is vital for self recognition. An examination of anosognosia for hemiplegia—the inability to recognise that one is paralysed down one side of one’s body—suggests the existence of ‘online’ and ‘offline’ representations of the body. Online representations of the body are representations of the body as it is currently, are newly constructed moment by moment and are directly “plugged into” current perception of the body. In contrast, offline representations of the body are representations of what the body (...) is usually like, are relatively stable and are constructed from online representations. This distinction is supported by an analysis of phantom limb—the feeling that an amputated limb is still present—phenomena. Initially it seems that the sense of embodiment may arise from either of these types of representation; however, an integrated representation of the body seems to be required. It is suggested information from vision and emotions is involved in generating these representations. A lack of access to online representations of the body does not necessarily lead to a loss in the sense of embodiment. An integrated offline representation of the body could account for the sense of embodiment and perform the functions attributed to this sense. (shrink)

Gottfried Wilhelm Leibniz was one of the central figures of seventeenth-century philosophy, and a huge intellectual figure in his age. This book from Glenn A. Hartz is an advanced study of Leibniz's metaphysics. Hartz analyzes a very complicated topic, widely discussed in contemporary commentaries on Leibniz, namely the question of whether Leibniz was a metaphysical idealist, realist, or whether he tried to reconcile both trends in his mature philosophy. Because Leibniz is notoriously unclear about this, much has been written (...) on the subject. In recent years, the debate has centered on whether it is possible to maintain compatibility between the two trends. In this controversial book, Hartz demonstrates that it is not possible to maintain compatibility of idealist and realist views - they must be understood as completely separate theories. As the first major work on realism in Leibniz's metaphysics, this key text will interest international Leibniz scholars, as well as students at the graduate level. (shrink)

In this paper, the relationship between the e-value of a complex hypothesis, H, and those of its constituent elementary hypotheses, Hj, j = 1… k, is analyzed, in the independent setup. The e-value of a hypothesis H, ev, is a Bayesian epistemic, credibility or truth value defined under the Full Bayesian Significance Testing mathematical apparatus. The questions addressed concern the important issue of how the truth value of H, and the truth function of the corresponding FBST structure M, relate to (...) the truth values of its elementary constituents, Hj, and to the truth functions of their corresponding FBST structures Mj, respectively.

The experience of embodiment may be studied using the rubber hand illusion. Little is known about the cognitive mechanism that elicits the feeling of embodiment. In previous models of the rubber hand illusion, bodily signals are processed sequentially. Such models cannot explain some more recent findings. Carruthers (2013) proposed a multidimensional model of embodiment, in which the processing of embodiment is understood in terms of conceptual hand space. Visual features of hands are represented along several dimensions. The rubber hand illusion (...) is then explained as the erroneous matching of the online representation of the artificial hand to the stored prototype in a space defined by those dimensions. We conducted the first experimental tests to investigate the multidimensional conceptual space account. First, participants performed a series of odd-one-out judgments for triads of hand images (including their own hand) and we then employed multidimensional scaling analyses. We found that a multidimensional model of perceived hand similarity could be fitted to our data. Second, we tested if a multisensory bodily signal manipulation (the rubber hand illusion) influences the position of the viewed artificial hand in hand space. We employed synchronous and asynchronous stroking and found that in the synchronous condition, which elicits the rubber hand illusion, compared to the asynchronous condition, which does not, the artificial hand was closer to the center of hand space; that is, to a prototype hand. We discuss these findings in the context of the Carruthers (2013) conceptual space model as well as other rubber hand illusion models. (shrink)

Conspiracy theories have largely been framed by the academy as a stigmatised form of knowledge. Yet recent scholarship has included calls to take conspiracy theories more seriously as an area of study with a desire to judge them on their own merits rather than an a priori dismissal of them as a class of explanation. This paper argues that the debates within the philosophy of religion, long overlooked by scholars of conspiracy theories, can help sow the seeds for re-examining our (...) understanding of conspiracy theories in a more balanced and nuanced way. The nature of religious belief is elemental to understanding the epistemological foundations of the conspiracy theorising worldview amidst what we may call ‘conspiratorial ambiguity’. Specifically, R.M. Hare's concept of bliks, which are unfalsifiable but meaningful worldviews, offers a way forward to reframe our approach towards the theory of conspiracy theories. (shrink)

Difficulties in distinguishing veridical reports of experience from confabulations have implications for theories of consciousness. I develop some of these implications through a consideration of out-of-body experiences (OBEs). Do these variations indicate individual variation in experience or are they post-hoc confabulations, stories told by subjects to themselves in an attempt to make sense of the core phenomenology? I argue that no existent or possible evidence would be sufficient to favour one hypothesis over the other. How such evidence is interpreted depends (...) on prior commitments to one or other of these hypotheses or to a theory of consciousness that is not neutral as to these hypotheses. One of these types of theory, namely vehicle theories, has difficulty accommodating the existence of confabulations and so allows for only the elaborate phenomenology hypothesis. Because we cannot know that reports are not confabulations, vehicle theories are insufficient to explain OBEs. (shrink)
