‘Sentience’ sometimes refers to the capacity for any type of subjective experience, and sometimes to the capacity to have subjective experiences with a positive or negative valence, such as pain or pleasure. We review recent controversies regarding sentience in fish and invertebrates and consider the deep methodological challenge posed by these cases. We then present two ways of responding to the challenge. In a policy-making context, precautionary thinking can help us treat animals appropriately despite continuing uncertainty about their sentience. In (...) a scientific context, we can draw inspiration from the science of human consciousness to disentangle conscious and unconscious perception (especially vision) in animals. Developing better ways to disentangle conscious and unconscious affect is a key priority for future research. (shrink)

This paper addresses what we consider to be the most pressing challenge for the emerging science of consciousness: the measurement problem of consciousness. That is, by what methods can we determine the presence of and properties of consciousness? Most methods are currently developed through evaluation of the presence of consciousness in humans and here we argue that there are particular problems in application of these methods to nonhuman cases—what we call the indicator validity problem and the extrapolation problem. The first (...) is a problem with the application of indicators developed using the differences between conscious and unconscious processing in humans to the identification of other conscious vs. nonconscious organisms or systems. The second is a problem in extrapolating any indicators developed in humans or other organisms to artificial systems. However, while pressing ethical concerns add urgency to the attribution of consciousness and its attendant moral status to nonhuman animals and intelligent machines, we cannot wait for certainty and we advocate the use of a precautionary principle to avoid causing unintentional harm. We also intend that the considerations and limitations discussed in this paper can be used to further analyze and refine the methods of consciousness science with the hope that one day we may be able to solve the measurement problem of consciousness.

One of the primary concerns in animal research is ensuring the welfare of laboratory animals. Modern views on animal welfare emphasize the role of animal sentience, i.e. the capacity to experience subjective states such as pleasure or suffering, as a central component of welfare. The increasing official recognition of animal sentience has had large effects on laboratory animal research. The Cambridge Declaration on Consciousness (Low et al., University of Cambridge, 2012) marked an official scientific recognition of the presence of sentience (...) in mammals, birds, and cephalopods. Animal sentience has furthermore been recognized in legislation in the European Union, UK, New Zealand and parts of Australia, with discussions underway in other parts of the world to follow suit. In this paper, we analyze this shift towards recognition of sentience in the regulation and practice in the treatment of laboratory animals and its effects on animal welfare and use. (shrink)

With increasing attention given to wild animal welfare and ethics, it has become common to depict animals in the wild as existing in a state dominated by suffering. This assumption is now taken on board by many and frames much of the current discussion; but needs a more critical assessment, both theoretically and empirically. In this paper, we challenge the primary lines of evidence employed in support of wild animal suffering, to provide an alternative picture in which wild animals may (...) often have lives that are far more positive than is commonly assumed. Nevertheless, while it is useful to have an alternative model to challenge unexamined assumptions, our real emphasis in this paper is the need for the development of effective methods for applying animal welfare science in the wild, including new means of data collection, the ability to determine the extent and scope of welfare challenges and opportunities, and their effects on welfare. Until such methods are developed, discussions of wild animal welfare cannot go beyond trading of intuitions, which as we show here can just as easily go in either direction. (shrink)

In this chapter we will explore new avenues for developing and defending Naïve Realism (also known as Relationalism), understood as a thesis about the phenomenal character of experience. The core claim of Naive Realism is that ‘what it’s like’ for a subject who enjoys a normal, successful perceptual experience of her surroundings consists in her being directly consciously aware of mind-independent entities in her external environment. It is widely agreed that the strongest challenge to Naïve Realism comes from the alleged (...) possibility of total hallucinations, and the orthodox line of response has been to adopt Disjunctivism about perceptual experience. In this chapter, we will instead focus on an emerging alternative family of responses, which we’ll call ‘New Wave Relationalism’ (NWR). The core commitment of NWR is to reject the initial assumption that there can be total hallucinations that are both non-relational and subjectively indistinguishable from genuine perceptions. The primary aim for this chapter will be to explore and defend this broad NWR strategy for responding to the threat posed by hallucinations to Naïve Realism. We will argue that which specific version or species of NWR a Naïve Realist should adopt will depend on their background methodological and metaphysical commitments. (shrink)

In this essay, we discuss Simona Ginsburg and Eva Jablonka’s The Evolution of the Sensitive Soul from an interdisciplinary perspective. Constituting perhaps the longest treatise on the evolution of consciousness, Ginsburg and Jablonka unite their expertise in neuroscience and biology to develop a beautifully Darwinian account of the dawning of subjective experience. Though it would be impossible to cover all its content in a short book review, here we provide a critical evaluation of their two key ideas—the role of Unlimited (...) Associative Learning in the evolution of, and detection of, consciousness and a metaphysical claim about consciousness as a mode of being—in a manner that will hopefully overcome some of the initial resistance of potential readers to tackle a book of this length.

One of the biggest problems in applications of animal welfare science is our ability to make comparisons between different individuals, both within and across species. Although welfare science provides methods for measuring the welfare of individual animals, there’s no established method for comparing measures between individuals. In this paper I diagnose this problem as one of underdetermination—there are multiple conclusions given the data, arising from two sources of variation that we cannot distinguish: variation in the underlying target variable (welfare experience) (...) and in the relationship of measured indicators to the target. I then describe some of the possible methods of making comparisons, based on the use of similarity assumptions that will have greater or lesser justification in different circumstances, and the alternative methods we may use when direct comparisons are not possible. In the end, all our available options for making welfare comparisons are imperfect, and we need to make explicit context-specific decisions about which will be best for the task at hand while acknowledging their potential limitations. Future developments in our understanding of the biology of sentience will help strengthen our methods of making comparisons. (shrink)

The convergence of computing, sensing, and communication technology will soon permit large-scale deployment of self-driving vehicles. This will in turn permit a radical transformation of traffic control technology. This paper makes a case for the importance of addressing questions of social justice in this transformation, and sketches a preliminary framework for doing so. We explain how new forms of traffic control technology have potential implications for several dimensions of social justice, including safety, sustainability, privacy, efficiency, and equal access. Our central (...) focus is on efficiency and equal access as desiderata for traffic control design. We explain the limitations of conventional traffic control in meeting these desiderata, and sketch a preliminary vision for a next-generation traffic control tailored to address better the demands of social justice. One component of this vision is cooperative, hierarchically distributed self-organization among vehicles. Another component of this vision is a priority system enabling selection of priority levels by the user for each vehicle trip in the network, based on the supporting structure of non-monetary credits.

One of the most challenging questions surrounding subjective animal welfare is whether these states are measurable: that is, is subjective welfare an appropriately quantifiable target for scientific enquiry and ethical and deliberative calculation? The availability of several different types of measurement scale raises important questions regarding whether subjective experience has the right properties to be meaningfully represented on the types of scale required for different applications. This methodological question has so far received scant attention in the animal welfare literature. In (...) this paper, I address this omission by examining the types of measurement scale we can reasonably expect to apply to animal welfare measurements, and which we will actually need for our applications. I argue that our different applications will require variously ordinal, interval, and ratio scales, and that we have sufficient reason to believe that subjective welfare is a target with the appropriate characteristics to justify the practice of representing it using each of these types of scales.

The study of introspection has, up until now, been predominantly human-centric, with regrettably little attention devoted to the question of whether introspection might exist in non-humans, such as animals and artificial intelligence (AI), and what distinct forms it might take. In their target article, Kammerer and Frankish (this issue) aim to address this oversight by offering a non-anthropocentric framework for understanding introspection that could be used to address these questions. However, their discussions on introspection in animals and AIs were quite (...) brief. In this commentary, we will build on their suggestions to offer some methodological guidance for how future research into introspection in animals and AIs might proceed. (shrink)

Vice epistemology is in the business of defining epistemic vice. One of the proposed requirements of epistemic vices is that they are reprehensible—blameworthy in a non-voluntarist way. Our problem, as vice epistemologists, is giving an analysis of non-voluntarist responsibility that will count just the right qualities, no more and no less, as epistemic vices. If our analysis of non-voluntarist responsibility ends up being too narrow, then it risks excluding some qualities that we want to count as epistemic vices, such as (...) implicit biases. Whereas, if it ends up being too broad, it risks including qualities that we do not want to count as epistemic vices, such as impaired vision. I recommend a three-step program for vice epistemologists: 1. admit that we have a responsibility problem; 2. strive to define the responsibility problem; 3. work together with specialists in non-voluntarist responsibility to solve the responsibility problem.

Meta-learning offers a promising framework to make sense of some parts of decision-making that have eluded satisfactory explanation. Here, we connect this research to work in animal behaviour and cognition in order to shed light on how and whether meta-learning could help us to understand the evolution of cognition.

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

This paper develops a formal model of the subtle meaning differences that exist between grammatical alternatives in socially conditioned variation and how these variants can be used by speakers as resources for constructing personal linguistic styles. More specifically, this paper introduces a new formal system, called social meaning games, which allows for the unification of variationist sociolinguistics and game-theoretic pragmatics, two fields that have had very little interaction in the past. Although remarks have been made concerning the possible usefulness of (...) game-theoretic tools in the analysis of certain kinds of socially conditioned linguistic phenomena :645–668, 1977; Dror et al. in Lang Linguist Compass 7:561–579, 2013; in Lang Linguist Compass 8:230–242, 2014; Clark in Meaningful games: Exploring language with game theory, MIT Press, Cambridge, MA, 2014, among others), a general framework uniting game-theoretic pragmatics and quantitative sociolinguistics has yet to be developed. This paper constructs such a framework through giving a formalization of the Third Wave approach to the meaning of variation using signalling games and a probabilistic approach to speaker/listener beliefs of the kind commonly used in the Bayesian game-theoretic pragmatics framework :3–44, 2016, for recent overviews).

In three parts, this volume in the AP-LS series explores the phenomena of captivity and risk management, guided and informed by the theory, method, and policy of psychological jurisprudence. The authors present a controversial thesis that demonstrates how the forces of captivity and risk management are sustained by several interdependent "conditions of control." These conditions impose barriers to justice and set limits on citizenship for one and all. Situated at the nexus of political/social theory, mental health law and jurisprudential ethics, (...) the book examines and critiques constructs such as offenders and victims; self and society; therapeutic and restorative; health; harm; and community. So, too, are three "total confinement" case law data sets on which this analysis is based. The volume stands alone in its efforts to systematically "diagnose" the moral reasoning lodged within prevailing judicial opinions that sustain captivity and risk management practices impacting: (1) the rights of juveniles found competent to stand criminal trial, the mentally ill placed in long-term disciplinary isolation, and sex offenders subjected to civil detention and community re-entry monitoring; (2) the often unmet needs of victims; and (3) the demands of an ordered society. Carefully balancing sophisticated insights with concrete and cutting-edge applications, the book concludes with a series of provocative, yet practical, recommendations for future research and meaningful reform within institutional practice, programming, and policy.

This paper presents a new style of semantic analysis for slurs: linguistic expressions used to denigrate individuals based on some aspects of their identity. As an illustration, the author will focus on one slur in particular: dyke, which is generally considered to be a derogatory term for lesbians. The author argues that not enough attention in the literature has been paid to the use of dyke by members of the target group, who can often use it in a non-insulting manner; (...) secondly, the author argues not enough attention has been paid to the use of the “neutral” form, lesbian, which is generally treated as having a simple, clear meaning, such as “engage[s] in same-sex sex”. Following McConnell-Ginet, the author argues that taking into account all the uses of both dyke and lesbian requires a new semantics and pragmatics for both terms. More specifically, the author proposes that dyke and lesbian are associated with different sets of personae: abstract identities or stereotypes. Dyke is associated with an anti-mainstream persona, which the vast majority of speakers views negatively; whereas, lesbian is associated with a mainstream persona, which many speakers view favourably. The author proposes that the semantic puzzles associated with dyke and lesbian can be resolved through the combination of a theory of these personae and a theory of how listeners’ beliefs about their interlocutors’ ideologies affect utterance interpretation.

Measurement of subjective animal welfare creates a special problem in validating the measurement indicators used. Validation is required to ensure indicators are measuring the intended target state, and not some other object. While indicators can usually be validated through looking for correlation between target and indicator under controlled manipulations, this is not possible when the target state is not directly accessible. In this paper, I outline a four-step approach using the concept of robustness, that can help with validating indicators of (...) subjective animal welfare. (shrink)

This article evaluates Alessandra Tanesini’s analyses of the intellectual virtues and vices of self-assessment, as characterized in her book The Mismeasure of the Self (2021 Tanesini, A. 2021. The Mismeasure of the Self. Oxford: Oxford University Press.[Crossref], [Google Scholar]). Section 1 explains Tanesini’s rich accounts of the virtues of intellectual humility and pride. Contra Tanesini, section 2 suggests an alternative account according to which the intellectual virtues of humility and pride require reliability about one’s limitations and strengths. This is an (...) externalist version of the limitations-owning analysis, which takes the virtues of intellectual humility and pride to consist in (roughly): dispositions to appropriately attend to and own one’s limitations and strengths (Whitcomb et al. 2017 Whitcomb, D., H. Battaly, J. Baehr, and D. Howard-Snyder. 2017. “Intellectual Humility: Owning Our Limitations.” Philosophy and Phenomenological Research 94 (3): 509–539. doi:10.1111/phpr.12228.[Crossref], [Web of Science ®], [Google Scholar]). I also explore whether the intellectual vices of self-assessment require unreliability about one’s limitations and strengths. In so doing, I raise a question about Tanesini’s analysis of self-abasement. (shrink)

This article argues that an interlocutor’s deference and open-mindedness can indicate servility rather than virtuous humility. Section 1 evaluates an influential philosophical analysis of the virtue of humility and two psychological measures, all of which emphasize the contrast between humility and arrogance. Section 2 develops a philosophical analysis of servility, building on the limitations-owning view. It argues that servility is an unwillingness or inability to be attentive to and own one’s strengths, and a disposition to be overly attentive to and (...) over-own one’s limitations. Section 3 sketches a picture of servility in political discourse, suggesting that we can expect servility to be positively correlated with deferring to others, open-mindedness, and belief-revision, and negatively correlated with anger. Section 4 sketches a picture of countering servility in political discourse through the virtues of pride and humility. By comparison with servility, we can expect virtuously proud and virtuously humble people to exhibit higher correlations with refusals to defer, to be open, to engage, and to revise beliefs. It points us toward psychological measures that aim to distinguish the virtue of humility from the vice of servility. (shrink)

Organizational aesthetics, both as a body of theory and a method of inquiry, is a rapidly expanding area of the organizational sciences. The Aesthetics of Organization accessibly draws key contributions delineating the emerging parameters of the field. It explains the significance of concepts devised by postmodern thinkers, through which emerge meaning and order in organizations. Methodological problems associated with investigations of the aesthetic are also highlighted so the reader can identify and understand the importance of recent ideas on vision, perspective (...) and periphery for learning in organizations. Through the contributions of leading international theorists, organizational aesthetics is defined in greater historical and theoretical depth, with a broad conceptual and practical range which academics will find invaluable.

Quassim Cassam (Cassam, Extremism, Routledge, 2022a) and Paul Katsafanas (Katsafanas, Philosopher’s Imprint 19:1–20, 2019) have argued that fanaticism and extremism are morally and epistemically vicious. I suggest an alternative approach that: (i) explains what makes fanaticism and extremism vicious in the very many cases in which they are; but also (ii) allows for cases in which fanaticism and extremism aren’t vices and may even be liberatory-virtues. My hope is that this approach might serve as a resource for those in liberatory (...) struggles. (shrink)

Some of the students in our classrooms doubt their intellectual strengths—their knowledge, abilities, and skills. They may be unaware of the intellectual strengths they have, or may ignore, lack confidence in, or under-estimate them. They may even incorrectly judge themselves to be intellectually inferior to their peers. Students who do such things consistently are deficient in the virtue of intellectual pride—in appropriately ‘owning’ their intellectual strengths—and are on their way to developing a form of intellectual servility. Can the ‘standard approach’ (...) to intellectual character education help these students make progress toward intellectual pride? This article argues that there are two limitations in its ability to help. First, the standard approach isn’t likely to help unless it is combined with classroom strategies for ameliorating servility. Second, even when it is combined with ameliorative strategies, any progress it might make in the classroom is likely to be fleeting when a student’s servility is caused by systemic epistemic injustice. This article suggests that rather than prioritize the standard approach, we prioritize strategies that aim at systemic change and amelioration. (shrink)

The goal of this article is to bring together two fields of research — animal sentience research and animal welfare science — with the aim of advancing our understanding of animal emotions, especially their subjectively experienced or 'felt' component (feelings). While these two research areas share a common interest in animal feelings, they have had surprisingly little interaction. In this paper, we make a call for the integration of these fields and outline some of the ways in which work done (...) in each of these areas can inform and benefit the other, such as strengthening the theoretical and conceptual bases of both fields, and sharing methods used by each, advocating further future collaboration for the benefit of both disciplines.

Dubourg and Baumard mention a potential role for the human drive to systemise as a factor motivating interest in imaginary worlds. Given that hyperexpression of this trait has been linked with autism (Baron-Cohen, 2002, 2006), we think this raises interesting implications for how those on the autism spectrum may differ from the neurotypical population in their engagement with imaginary worlds.

While animal sentience research has flourished in the last decade, scepticism about our ability to accurately measure animal feelings has unfortunately remained fairly common. Here, we argue that evolutionary considerations about the functions of feelings will give us more reason for optimism and outline a method for how this might be achieved.

Extensive training with a musical instrument results in the automatisation of the bodily operations needed to manipulate the instrument: the performer no longer has to consciously think about the instrument while playing. The ability of the performer to automate operations on the instrument is due to sensorimotor mechanisms that can predict changes in the state of the body and the instrument in response to motor commands. But how strong are these mechanisms? To what extent can we alter the structure of (...) the instrument before they disappear? We performed an exploratory study to understand whether and how sensorimotor predictions survive instrument modification. We asked seven professional violinists to perform repertoire pieces and sight-reading exercises on four different violins: their own, a cheap violin, a small violin, and a violin whose strings had been put on in reverse order. We performed a series of quantitative investigations on performance intonation and duration, and on bowing gestures and errors. The analysis revealed that participants struggled adapting to the altered instruments, suggesting that prediction mechanisms are a function of instrument configuration. In particular, the analysis of bowing errors, intonation, and of performance duration suggested that the performance with the reverse violin was much less fluent and precise than the performer's own instrument; the performance with the small violin was also sub-standard though to a lesser extent. We also observed that violinists were differently affected by instrument modifications, suggesting that the capability to adapt to a new instrument is highly personal. (shrink)

For nearly two decades, the process of reviewing the ethical merit of research involving human subjects has been based on the application of principles initially described in the U.S. National Commission's Belmont Report, and later articulated more fully by Beauchamp and Childress in their Principles of Biomedical Ethics. Recently, the use of ethical principles for deliberating about moral problems in medicine and research, referred to in the pejorative sense as “principlism”, has come under scrutiny. In this paper we argue that (...) these principles can provide a foundation for the source of ethical appraisal of human research, but are not themselves wholly adequate for this purpose. Therefore, we further propose that principles should be understood as heuristics that can be “specified” as described by DeGrazia , and that the principle‐based approach should be supplemented by formally incorporating “sensitivity to context” into the evaluation of clinical trials.

Euglenids comprise a group of single‐celled eukaryotes with diverse modes of nutrition, including phagotrophy and photosynthesis. The level of morphological diversity present in this group provides an excellent system for demonstrating evolutionary transformations in morphological characters. This diversity also provides compelling evidence for major events in eukaryote evolution, such as the punctuated effects of secondary endosymbiosis and mutations in underlying developmental mechanisms. In this essay, we synthesize evidence for the origin, adaptive significance and diversification of the euglenid cytoskeleton, especially pellicle (...) ultrastructure, pellicle surface patterns, pellicle strip number and the feeding apparatus. We also highlight holes in our knowledge that must be filled before we are able to confidently describe euglenid cell biology and infer the earliest stages in euglenid evolution. Nonetheless, by possessing combinations of characters resulting from adaptive change and morphostasis, euglenids have retained key pieces of evidence necessary for reconstructing the early evolution and diversification of eukaryotic life.

Individuals differ greatly in their ability to learn and navigate through environments. One potential source of this variation is “directional sense” or the ability to identify, maintain, and compare allocentric headings. Allocentric headings are facing directions that are fixed to the external environment, such as cardinal directions. Measures of the ability to identify and compare allocentric headings, using photographs of familiar environments, have shown significant individual and strategy differences; however, the neural basis of these differences is unclear. Forty-five college students, (...) who were highly familiar with a campus environment and ranged in self-reported sense-of-direction, underwent fMRI scans while they completed the Relative Heading task, in which they had to indicate the direction of a series of photographs of recognizable campus buildings (i.e., “target headings”) with respect to initial “orienting headings”. Large individual differences were found in accuracy and correct decision latencies, with gender, self-reported sense-of-direction, and familiarity with campus buildings all predicting task performance. Using linear mixed models, the directional relationships between headings and the experiment location also impacted performance. Structural scans revealed that lateral orbitofrontal and superior parietal volume were related to task accuracy and decision latency, respectively. Bilateral hippocampus and right presubiculum volume were related to self-reported sense-of-direction. Meanwhile, functional results revealed clusters within the superior parietal lobule, supramarginal gyrus, superior frontal gyrus, lateral orbitofrontal cortex, and caudate among others in which the intensity of activation matched the linear magnitude of the difference between the orienting and target headings. While the retrosplenial cortex and hippocampus have previously been implicated in the coding of allocentric headings, this work revealed that comparing those headings additionally involved frontal and parietal regions. These results provide insights into the neural bases of the variation within human orientation abilities, and ultimately, human navigation. (shrink)
