Sentience is the capacity to have feelings, such as feelings of pain, pleasure, hunger, thirst, warmth, joy, comfort and excitement. It is not simply the capacity to feel pain, but feelings of pain, distress or harm, broadly understood, have a special significance for animal welfare law. Drawing on over 300 scientific studies, we evaluate the evidence of sentience in two groups of invertebrate animals: the cephalopod molluscs or, for short, cephalopods (including octopods, squid and cuttlefish) and the decapod crustaceans or, (...) for short, decapods (including crabs, lobsters and crayfish). We also evaluate the potential welfare implications of current commercial practices involving these animals. (shrink)

It would be unwise to dismiss the possibility of human brain organoids developing sentience. However, scepticism about this idea is appropriate when considering current organoids. It is a point of consensus that a brain-dead human is not sentient, and current organoids lack a functioning brainstem. There are nonetheless troubling early warning signs, suggesting organoid research may create forms of sentience in the near future. To err on the side of caution, researchers with very different views about the neural basis of (...) sentience should unite behind the “brainstem rule”: if a neural organoid develops or innervates a functioning brainstem that regulates arousal and leads to sleep-wake cycles, then it is a sentience candidate. If organoid research leads to the creation of sentience candidates, a moratorium or indefinite ban on the creation of the relevant type of organoid may be appropriate. A different way forward, more consistent with existing approaches to animal research, would be to require ethical review and harm-benefit analysis for all research on sentience candidates. (shrink)

Over the past two decades, Ginsburg and Jablonka have developed a novel approach to studying the evolutionary origins of consciousness: the Unlimited Associative Learning framework. The central idea is that there is a distinctive type of learning that can serve as a transition marker for the evolutionary transition from non-conscious to conscious life. The goal of this paper is to stimulate discussion of the framework by providing a primer on its key claims and a clear statement of its main empirical (...) predictions. (shrink)

Hamilton’s theory of kin selection is the best-known framework for understanding the evolution of social behavior but has long been a source of controversy in evolutionary biology. A recent critique of the theory by Nowak, Tarnita, and Wilson sparked a new round of debate, which shows no signs of abating. In this overview, we highlight a number of conceptual issues that lie at the heart of the current debate. We begin by emphasizing that there are various alternative formulations of Hamilton’s (...) rule, including a general version, which is always true; an proximate version, which assumes weak selection; and a special version, which demands other restrictive assumptions. We then examine the relationship between the neighbor-modulated fitness and inclusive fitness approaches to kin selection. Finally, we consider the often-strained relationship between the theories of kin and multilevel selection. (shrink)

Hamilton introduced two conceptions of social fitness, which he called neighbour-modulated fitness and inclusive fitness. Although he regarded them as formally equivalent, a re-analysis of his own argument for their equivalence brings out two important assumptions on which it rests: weak additivity and actor's control. When weak additivity breaks down, neither fitness concept is appropriate in its original form. When actor's control breaks down, neighbour-modulated fitness may be appropriate, but inclusive fitness is not. Yet I argue that, despite its more (...) limited domain of application, inclusive fitness provides a distinctively valuable perspective on social evolution. (shrink)

This book is about the liberation of the concept of life from the bondage fashioned by the interpreters of life ever since biology began, and about the liberation of the life of humans and non-humans alike from the bondage of social structures and behaviour, which now threatens the fullness of life's possibilities if not survival itself. It falls into a tradition of writings about human problems from a perspective informed by biology. It rejects the mechanistic model of life dominant in (...) the Western world and develops an alternative 'ecological model' which is applicable to the life of the cell and the life of the human community. For the first time it brings together in one work the insights of modern biology with those of a modern holistic philosophy and a liberal theology in a way which challenges conventional approaches to science, agriculture, sociology, politics, economics, development and liberation movements.

The hunt for a biologically respectable definition for the folk concept of innateness is still on. I defend Ariew’s Canalization account of innateness against the criticisms of Griffiths and Machery, but highlight the remaining flaws in this proposal. I develop a new analysis based on the notion of environmental induction. A trait is innate, I argue, iff it is not environmentally induced. I augment this definition with a novel analysis of environmental induction that draws on the contrastive nature of causal (...) explanation. Whether a trait is environmentally induced, I argue, depends on a context sensitive contrast class. I argue that a “Noninduction” analysis of innateness allows the concept an explanatory role in biology. I show how my proposal co-opts the successes of the Canalization account whilst avoiding its pitfalls, and I account for why biologists associate a range of disparate properties with innateness.

Brich convincingly argues that science and religion must come together if we are to heal and renew our planet.

One key aim of Grafen’s Formal Darwinism project is to formalize ‘modern biology’s understanding and updating of Darwin’s central argument’. In this commentary, I consider whether Grafen has succeeded in this aim.

A crucially important part of the biosphere – the virosphere – is too often overlooked. Inclusion of the virosphere into the global picture of protein structure space reveals that 63 protein domain superfamilies in viruses do not have any structural and evolutionary relatives in modern cellular organisms. More than half of these have functions which are not virus‐specific and thus might be a source of new folds and functions for cellular life. The number of viruses on the planet exceeds that (...) of cells by an order of magnitude and viruses evolve up to six orders of magnitude faster. As a result, cellular species are subject to a constitutive ‘flow‐through’ of new viral genetic material. Due to this and the relaxed evolutionary constraints in viruses, the transfer of domains between host‐to‐virus could be a mechanism for accelerated protein evolution. The virosphere could be an engine for the genesis of protein structures, and may even have been so before the last universal common ancestor of cellular life. (shrink)

This is an edited transcript of a lecture given at the LSE in March 2023. The lecture introduces the “meaning of life” question via Tolstoy’s Confession, then considers the strengths and limitations of religious and secular answers to the question.

Around the world, practitioners and academics are engaging in the rise of regenerative farming. On the margins of the predominant farming system, and often with little support and acknowledgement, regenerative farming is surprisingly persistent and represents a radical response to industrialization, ecological crises and alienation. This study uses feminist theories to grasp farmers’ regenerative experiences and explores how dialogical methodologies can create collective thinking among farmers and between academia and practice. The study is based on dialogues and iterative writing between (...) three female researchers and two female regenerative farmers in Denmark in which we explore regenerative farming practices, female perspectives, feminist (more-than-human) care, and the sustainability crises we are facing today and in the future. The exchange of thoughts provides insights into what it is to be human in farming, including more-than-human relationships, as well as reflections on composting as a reproductive practice, and the (quiet) revolutionary potential of regenerative farming. Thus, we experience how creating collective thinking about common concerns across academia and practice can entail feelings of being part of a community as well as involve actual consequences and risks. Finally, it reminds us that sharing fragility by laying bare our work (and thoughts) as both researchers and practitioners allows for careful dialogues and valuable insights. (shrink)

Contemporary, technoscientific capitalism is characterized by the configuration of a range of “things” as assets or capitalized property. Accumulation strategies have changed as a result of this assetization process. Rather than entrepreneurial strategies based on commodity production, technoscientific capitalism is increasingly underpinned by rentiership or the appropriation of value through ownership and control rights, monopoly conditions, and regulatory or market devices and practices. While rentiership is often presented as a negative phenomenon in both neoclassical and Marxist political economy literatures—and much (...) in between—in this paper, I conceptualize rentiership as a technoeconomic practice and process framed by insights from science and technology studies. So, rather than a problematic “side effect” of capitalism, the concept of rentiership enables us to understand how different forms of value extraction constitute, and are constituted by, different forms of technoscience. This allows STS to contribute a distinctive analytical approach to ongoing debates in political economy about economic rents and rent-seeking. (shrink)

Skyrms, building on the work of Dretske, has recently developed a novel information-theoretic account of propositional content in simple signalling systems. Information-theoretic accounts of content traditionally struggle to accommodate the possibility of misrepresentation, and I show that Skyrms’s account is no exception. I proceed to argue, however, that a modified version of Skyrms’s account can overcome this problem. On my proposed account, the propositional content of a signal is determined not by the information that it actually carries, but by the (...) information that it would carry at the nearest separating equilibrium of the underlying evolutionary dynamics. I show that this amended account yields reasonable ascriptions of false propositional content in a well-known formal model of the evolution of communication , and close with a discussion of the serious but perhaps not insuperable difficulties we face in applying the account to examples of signalling in the real world.

The paper observes the relation of fictional/figural discourses to language-games that are active in reality. The starting point for the discussion is the "theory of two contexts" by Arne Merilai, the basic idea of which is distinguishing between fictional and factual speech acts on the basis of their different contexts of truth value. It seems to be justified to expand it to the whole sphere of figurality. After that the paper views John Gibson’s Wittgensteinian theory of fiction as an archive (...) of standards/etalons of languagegames and a laboratory of reshaping and creating these standards. The fictional/figural sphere can be described as the area of possibility that creates language-games of reality via poiesis. The article describes some cases where the logic of figural sphere is introduced directly into real political discourse, forcing the reality to act according to the rules of art, but thus excluding the ethical freedom of our real-life language-games. It means that there exists a certain principle of metonymy between the figural sphere as archive and laboratory of standards, on the one hand, and the language-games of reality, on the other hand, while violation of that principle involves a danger of losing the reconciliatory power of fictionality/figurality that, according to Jaak Tomberg, is a significant function of literature as a human practice. There are several possibilities for further analysis: the cases where the danger can be turned into something positive; the problems and gains of art forms that use techniques of intrusion into reality; the question if such violation of the "principle of metonymy" is specifically connected with modernist avant-gardism or not.

Annotation. "What is life? What does it means to be alive? Is the Earth a super-organism? Is God necessary? In Biology and the Riddle of Life Charles Birch confronts these fundamental questions at a time when such topics as genetic engineering, cloning and ecology have been prominent in the news. Birch confronts the impression that modern biology has answers to all that there is to be known about life. We need to move towards an understanding of living creatures (...) as subjects, and not only as objects, in order to probe life's hidden secrets - what it is to be alive, what it is to experience pain, and what it is to be in love. The answer must include the meaning of life for us as individuals. Birch proposes a new perspective to bring subject and object together. This is the black box he has opened."--BOOK JACKET.

Could emotions be a uniquely human phenomenon? One prominent theory in emotion science, Lisa Feldman Barrett’s Theory of Constructed Emotion (tce), suggests they might be. The source of the sceptical challenge is that tce links emotions to abstract concepts tracking socio-normative expectations, and other animals are unlikely to have such concepts. Barrett’s own response to the sceptical challenge is to relativize emotion to the perspective of an interpreter, but this is unpromising. A more promising response may be to amend the (...) theory, dropping the commitment to the abstract nature of emotion concepts and allowing that, like olfactory concepts, they have disjunctive sensory groundings. Even if other animals were emotionless, this would not imply they lack morally significant interests. Unconceptualized valenced experiences are a sufficient basis for morally significant interests, and such experiences may occur even in the absence of discrete, constructed emotions. (shrink)

The article attempts to show some limitations to reductive accounts in science and philosophy of body-mind relations, experience and skill. Extensive literature has developed in analytic philosophy of mind recently due to new technology and theories in the neurosciences. In the sporting sciences, there are also attempts to reduce experiences and skills to biology, mechanics, chemistry and physiology. The article argues there are three fundamental problems for reductive accounts that lead to an explanatory gap between the reduction and the conscious (...) experience. First, reductive accounts deal with objective observations; conscious experiences are subjective. Second, subjective experience seems difficult to identify with physical events described by chemistry, biology, mechanics or neurophysiology. Finally, sport involves knowing how and knowing how is also difficult to reduce to propositional knowledge, which is the reductive scientific/philosophical project. The article argues that sport provides an excellent platform to better understand what is wrong with reductive analysis in body-mind relations, since both conscious experience and knowing how are fundamental to sport performance.

Some patients, following brain injury, do not outwardly respond to spoken commands, yet show patterns of brain activity that indicate responsiveness. This is “cognitive-motor dissociation” (CMD). Recent research has used machine learning to diagnose CMD from electroencephalogram (EEG) recordings. These techniques have high false discovery rates, raising a serious problem of inductive risk. It is no solution to communicate the false discovery rates directly to the patient’s family, because this information may confuse, alarm and mislead. Instead, we need a procedure (...) for generating case-specific probabilistic assessments that can be communicated clearly. This article constructs a possible procedure with three key elements: (1) a shift from categorical “responding or not” assessments to degrees of evidence; (2) the use of patient-centred priors to convert degrees of evidence to probabilistic assessments; and (3) the use of standardized probability yardsticks to convey those assessments as clearly as possible.

A conversation between three characters: Credulus, who thinks conscious mental states can and should be attributed to other animals without any need for scientific inquiry; Skepticus, a critic with behaviorist leanings; and Moderus, who sees a middle path in the emerging science of animal consciousness.

This essay was prompted by the question of how Hathayoga, literally 'the Yoga of force', acquired its name. Many Indian and Western scholars have understood the 'force' of Haṭhayoga to refer to the effort required to practice it. Inherent in this understanding is the assumption that Haṭhayoga techniques such as _praṇayama_ are strenuous and may even cause pain. Others eschew the notion of force altogether and favor the so-called 'esoteric' definition of Haṭhayoga and moon in the body). This essay examines (...) these interpretations in light of definitions of _haṭhayoga_ and the adverbial uses of _haṭha_ in Sanskrit Yoga texts that predate the fifteenth-century _Hathapradipika_.

In an incendiary 2010 Nature article, M. A. Nowak, C. E. Tarnita, and E. O. Wilson present a savage critique of the best-known and most widely used framework for the study of social evolution, W. D. Hamilton’s theory of kin selection. More than a hundred biologists have since rallied to the theory’s defence, but Nowak et al. maintain that their arguments ‘stand unrefuted’. Here I consider the most contentious claim Nowak et al. defend: that Hamilton’s rule, the core explanatory principle (...) of kin selection theory, ‘almost never holds’. I first distinguish two versions of Hamilton’s rule in contemporary theory: a special version (HRS) that requires restrictive assumptions, and a general version (HRG) that does not. I then show that Nowak et al. are most charitably construed as arguing that HRS almost never holds, while HRG buys its generality at the expense of explanatory power. While their arguments against HRS are fairly uncontroversial, their arguments against HRG are more contentious, yet these have been largely overlooked in the ensuing furore. I consider the arguments for and against the explanatory value of HRG, with a view to assessing what exactly is at stake in the debate. I suggest that the debate hinges on issues concerning the causal interpretability of regression coefficients, and concerning the explanatory function Hamilton’s rule is intended to serve. (shrink)

When we talk about ideology and new genetics we tend to think of concepts like geneticisation and genetic essentialism, which present genetics and biology in deterministic terms. However, the aim of this article is to consider how a particular economic ideology - neoliberalism - has affected the bioeconomy rather than assuming that it is the inherent qualities of biotechnology that determine market value. In order to do this, the paper focuses on the discourses and practices of economic competitiveness that pervade (...) biotechnology policy-making in the UK, Europe and the USA. Finally it will consider how the manufacture of scarcity - in order to produce the bioeconomy - has led to a problematic focus on a specific innovation paradigm that may prove detrimental to the development and distribution of new biotechnologies.

Nick Bostrom’s ‘Simulation Argument’ purports to show that, unless we are confident that advanced ‘posthuman’ civilizations are either extremely rare or extremely rarely interested in running simulations of their own ancestors, we should assign significant credence to the hypothesis that we are simulated. I argue that Bostrom does not succeed in grounding this constraint on credence. I first show that the Simulation Argument requires a curious form of selective scepticism, for it presupposes that we possess good evidence for claims about (...) the physical limits of computation and yet lack good evidence for claims about our own physical constitution. I then show that two ways of modifying the argument so as to remove the need for this presupposition fail to preserve the original conclusion. Finally, I argue that, while there are unusual circumstances in which Bostrom’s selective scepticism might be reasonable, we do not currently find ourselves in such circumstances. There is no good reason to uphold the selective scepticism the Simulation Argument presupposes. There is thus no good reason to believe its conclusion. (shrink)
