This paper examines the logic of conditional obligation, which originates from the works of Hansson, Lewis, and others. Some weakened forms of transitivity of the betterness relation are studied. These are quasi-transitivity, Suzumura consistency, acyclicity and the interval order condition. The first three do not change the logic. The axiomatic system is the same whether or not they are introduced. This holds true under a rule of interpretation in terms of maximality and strong maximality. The interval order condition gives rise (...) to a new axiom. Depending on the rule of interpretation, this one changes. With the rule of maximality, one obtains the principle known as disjunctive rationality. With the rule of strong maximality, one obtains the Spohn axiom (also known as the principle of rational monotony, or Lewis’ axiom CV). A completeness theorem further substantiates these observations. For interval order, this yields the finite model property and decidability of the calculus. (shrink)

In his Metaphysical Disputation 5, Francisco Suárez offers a concise argument to the effect that all that does or can possibly exist is singular and individual, and that a commitment to real universals would entail what he calls a ‘manifest contradiction’. According to a recent interpretation of this Master Argument against realism, it reveals that Suárez was committed to a hylomorphic version of the principle of the identity of indiscernibles, and ruled out the possibility of perfectly similar yet numerically distinct (...) entities. In this paper, however, I argue that (1) at least for fundamental items in his ontology such as immaterial forms and matter-form compounds, Suárez was not committed to the identity of indiscernibles, and (2) a reading of the Master Argument that does justice to this is available. On the basis of this reading I provide a reappraisal of the argument, and conclude that (3) it rests on a premise that the realist would have good reasons to challenge. Hence, while the argument seems consistent with the possibility of indiscernible yet numerically distinct immaterial forms and matter-form compounds Suárez wishes to allow for, it is doubtful whether it can accomplish what it sets out to do, and undermine the case for realism.

Hope has been an important topic in philosophy since its beginnings. One can identify three main sources of interest in hope: Hope can be relevant in a religious framework (for example, when Thomas Aquinas discusses hope as one of the theological virtues, or when Immanuel Kant discusses the question ‘What may I hope?’ in connection with God’s existence and immortality); hope has been assigned a positive role in politics (for example, by Ernst Bloch in his monumental Marxist work The Principle (...) of Hope, by John Rawls in his defence of a ‘realist utopia’ or by pragmatists like Richard Rorty and Cornel West); and hope has been considered part of the human moral psychology (for example, when treated as an emotion by ancient Greek philosophy or in accounts of the passions in the works of Enlightenment thinkers). In recent decades, there has been a surge of interest in hope in analytically oriented philosophy, which centres on the moral psychology of hope (see, for example, Martin 2013). This debate is animated by the questions of what hope is and when it is valuable and rational. In her fascinating book, Katie Stockdale proceeds from and contributes to this debate, but does so with a specific political interest: she investigates the role, value and rationality of hope in contexts of oppression, such as those caused by colonialism, racism and sexism. She engages with feminist approaches in moral, social and political philosophy and develops her account in dialogue with literary writings that provide real-world examples of experiences of hope and hopelessness. In doing so, Stockdale broadens the scope for thinking about hope and provides an admirable piece of philosophy that is connected to real experiences. One further significant—and in my view laudable—feature of her approach is that her aim is not to defend a uniquely positive role of hope, but rather to provide a nuanced discussion of its advantages and dangers, as well as the value of hopelessness (for example, as involved in bitterness).

Hsueh M. Qu has recently argued that Hume’s famed ‘Separability Principle’ from the Treatise entangles him in a contradiction. Qu offers a modified principle as a solution but also argues that the mature Hume would not have needed to avail himself of it, given that Hume’s arguments in the first Enquiry do not depend on this principle in any form. To the contrary, I show that arguments in the first Enquiry depend on this principle, but I agree with Qu that (...) Qu’s solution to Hume’s quandary frees him of the contradiction. Next, I compare Qu’s solution to Hume’s original position. By analysing the divergent forms of 'Hume’s Dictum’ that follow from them, I show that Qu’s solution and Hume’s original position have significantly different consequences in a range of domains, including Hume’s modality. Generally, Qu’s solution fits better with Hume’s other commitments—even though Hume often fails to recognize it—thereby increasing its plausibility. (shrink)

The search for extraterrestrial life centres on the search for ‘biosignatures’. Yet there is little agreement within the scientific community with respect to what exactly it is for something to be a biosignature. Existing accounts are presented and criticised. An alternative is provided that resolves problems with existing accounts by distinguishing clearly between types and tokens.

In a recent paper, Yoaav Isaacs, Alan Hájek, and John Hawthorne argue for the rational permissibility of "credal imprecision" by appealing to certain propositions associated with non-measurable spatial regions: for example, the proposition that the pointer of a spinner will come to rest within a certain non-measurable set of points on its circumference. This paper rebuts their argument by showing that its premises lead to implausible consequences in cases where one is trying to learn, by making multiple observations, whether a (...) certain outcome is associated with a non-measurable region or a measurable one.

I present a novel account of unconditional obligation and of its relationship to conditional obligation and bring this account to bear upon Chisholm's puzzle concerning contrary-to duty obligation.

Our decision-theoretic states are not luminous. We are imperfectly reliable at identifying our own credences, utilities and available acts, and thus can never be more than imperfectly reliable at identifying the prescriptions of decision theory. The lack of luminosity affords decision theory a remarkable opportunity — to issue guidance on the basis of epistemically inaccessible facts. We show how a decision theory can guarantee action in accordance with contingent truths about which an agent is arbitrarily uncertain. It may seem that (...) such advantages would require dubiously adverting to externalist facts that go beyond the internalism of traditional decision theory, but this is not so. Using only the standard repertoire of decision-theoretic tools, we show how to modify existing decision theories to take advantage of this opportunity. These improved decision theories require agents to maximize conditional expected utility — expected utility conditional upon an agent’s actual decision situation. We call such modified decision theories ‘self-confident’. These self-confident decision theories have a distinct advantage over standard decision theories: their prescriptions are better. (shrink)

Conceptual engineering is the enterprise of evaluating and improving our representational devices. But how should we conduct this enterprise? One increasingly popular answer to this question proposes that conceptual engineering should proceed in terms of the functions of our representational devices. In this paper, we argue that the best way of understanding this suggestion is in terms of normative functions, where normative functions of concepts are, roughly, things that they allow us to do that matter normatively (for example, things in (...) virtue of which we have normative reasons to have these concepts). Not only does this introduce a novel view about functions to the literature. This proposal also fits more naturally than the alternatives with conceptual engineering as a normative enterprise, and it allows functions to play all of the explanatory roles assigned to them in the conceptual engineering literature. Our discussion of the explanatory advantages of normative functions also advances the understanding of the ways in which concepts can be authoritative, what this means for conceptual engineering, and highlights the importance of political philosophy for thinking about conceptual engineering in practice. Furthermore, the paper explicates what kind of role considerations about function can and should actually play in conceptual engineering. (shrink)

There’s the question of what there is, and then there’s the question of what ultimately exists. Many contend that, once we have this distinction clearly in mind, we can see that there is no sensible debate to be had about whether there are such things as properties or tables or numbers, and that the only ontological question worth debating is whether such things are ultimate (in one or another sense). I argue that this is a mistake. Taking debates about ordinary (...) objects as a case study, I show that the arguments that animate these debates bear directly on the question of which objects there are and cannot plausibly be recast as arguments about what’s ultimate. I then address the objection that, because they are easy answerable, questions about what there is cannot be a proper subject of ontological debate. (shrink)

This article aims to make public part of the research on the concept of ‘light’ in the theological and, above all, liturgical tradition of the Greek Orthodox Church, based on its representation of the concept of ‘hypostasis’. Taking as a point of departure the interpretation of the expression ‘light of light’ [φῶς ἐκ φωτός (phôs ek phōtos)] of the text of the Niceno-Constantinopolitan Symbol, the article presents a proposal for the interpretation of the concept of ‘representation’ for this specific case, (...) based on the idea of apomímesis, and applies this concept to a reading of the place of ‘light’ in the Holy Scripture, in the Patrology and in the Greek Eastern Liturgies.

This paper navigates the relationship between the growing influence of Artificial Intelligence (AI) and the foundational principles of academic integrity. It offers an in-depth analysis of how key academic stakeholders—publishers and universities—are crafting strategies and guidelines to integrate AI into the sphere of scholarly work. These efforts are not merely reactionary but are part of a broader initiative to harness AI’s potential while maintaining ethical standards. The exploration reveals a diverse array of stances, reflecting the varied applications of AI in (...) academic settings. These range from conservative approaches emphasizing the need for stringent AI regulations to more progressive strategies that seek to leverage AI’s capabilities. The paper accentuates the importance of guidelines that are adaptable, transparent, and culturally sensitive, acknowledging the global context of academic research. It also highlights the pressing need for effective implementation and enforcement of these guidelines to ensure that the integration of AI into academia does not compromise the integrity of scholarly work. The conclusion emphasizes the dynamic balance required between embracing AI’s transformative potential and upholding the timeless values of academic rigor and ethical research. This comprehensive analysis aims to provide a detailed perspective on the evolving role of AI in academia, fostering a dialog on how best to navigate this new technological frontier while preserving the sanctity of academic scholarship.

Research and activism have increasingly denounced the problematic environmental record of the infrastructure and value chain underpinning artificial intelligence (AI). Water-intensive data centres, polluting mineral extraction and e-waste dumping are incontrovertibly part of AI’s footprint. In this article, I turn to areas affected by AI-fuelled environmental harm and identify an ethics of resistance emerging from local activists, which I term ‘elemental ethics’. Elemental ethics interrogates the AI value chain’s problematic relationship with the elements that make up the world, critiques the (...) undermining of local and ancestral approaches to nature and reveals the vital and quotidian harms engendered by so-called intelligent systems. While this ethics is emerging from grassroots and Indigenous groups, it echoes recent calls from environmental philosophy to reconnect with the environment via the elements. In empirical terms, this article looks at groups in Chile resisting a Google data centre project in Santiago and lithium extraction (used for rechargeable batteries) in Lickan Antay Indigenous territory, Atacama Desert. As I show, elemental ethics can complement top-down, utilitarian and quantitative approaches to AI ethics and sustainable AI as well as interrogate whose lived experience and well-being counts in debates on AI extinction.

This study examines the procedural ethical considerations surrounding religious exemptions to Covid vaccine mandates, specifically focusing on immigrant healthcare personnel (HCP) and HCPs of color. It emphasizes communication issues with applicants by investigating exemption applications and their accompanying guidelines. While there is extensive literature on the ethical implications of religious exemptions, a notable gap remains in addressing the procedural aspects of religious exemption applications and their reviewing processes. The study scrutinized religious exemption application forms and accompanying guidelines from 32 selected (...) non-teaching and teaching hospitals for the years 2022–2023. The findings highlight significant variability in exemption application criteria and processes across institutions. Importantly, many application forms lacked comprehensive procedural information, which may result in subjective evaluations and potential misinterpretations of non-Western and non-mainstream religious beliefs, especially those of immigrant HCPs and HCPs of color. The study proposes various strategies to advocate for more equitable and transparent procedures, underlining the significance of diversity, equity, and inclusion in the religious exemption review process for vaccine mandates.

Paracelsus was a transmutational alchemist: For most of his career, he believed that one metal could be turned into another. In an alchemical text, the De renovatione et restauratione, he explored the theoretical foundations of transmutation and hinted at recipes for bringing it about. He proposed that from plants, gems, metals, and minerals might be prepared a class of marvelous medicaments, which he called prima entia (first entities). Each primum ens had particular uses, but the entia were all supposed to (...) be able to revitalize the human body and cleanse it of disease. Certain entia could also transmute metals. The De renovatione et restauratione affirmed the metaphysical centrality, in goldmaking and medicine alike, not just of purification or alteration but of renewal and transformation. It expressed the author’s eschatological excitement at God’s works of wonder, whether within or above nature. (shrink)

Commentators generally agree that Foucher presumes the resemblance theory of representation and uses it to substantiate external world skepticism. In this paper, I challenge this picture. First, I argue that he does not assume that representation is reducible to, or even just works through, resemblance between representation and object. Indeed, his functional-similarity theory primarily appeals to resemblance between the respective effects the representation and the object (would) have on our minds. I also propose that his argument for the resemblance-requirement of (...) representation depends on the causal likeness principle, and clarify its role in Foucher’s theory. Second, I show that his main interest lies with representation in the sense of truthfully making the object present. Accordingly, when Foucher concludes that we can only represent our own ideas, he merely means that our ideas reveal the ways objects affect us through our senses, as opposed to how they are in themselves.

Dans cette question sur le livre II des Sentences, Guiral Ot demande si la créature, avant sa création, a un être propre, distinct de celui du Créateur : d’une part, Dieu crée ex nihilo ; avant la création, il n’y a donc rien, hormis Dieu ; d’autre part, Dieu connaît et veut de toute éternité ce qu’il produira avant de le produire ; les créatures ont bien un être-connu et un être-voulu en Dieu. Pour répondre à cette difficulté, Duns Scot (...) avait admis un être possible et un être relatif des créatures dans la pensée divine.

Dans la première moitié du xii e siècle, les chartrains créent un lexique spécialisé pour l’optique en sélectionnant des termes sans connotation théologique et en leur ajoutant un sens géométrique. Grâce à Constantin l’Africain, ils y intègrent l’ophtalmologie. Alors que ce lexique est utilisé par les traducteurs gréco-latins, les traducteurs arabo-latins, à l’exception de l’Émir Eugène de Sicile, ignorent largement ces spécialisations sémantiques. L’hétérogénéité des choix des traducteurs réintroduit ainsi une incertitude lexicale qui nécessite une clarification des concepts et une (...) sélection des termes.

Recent advancements in algorithms for abstract argumentation make it possible now to solve reasoning problems even with argumentation frameworks of large size, as demonstrated by the results of the various editions of the International Competition on Computational Models of Argumentation (ICCMA). However, the solvers participating to the competition may be hard to use for non-expert programmers, especially if they need to incorporate these algorithms in their own code instead of simply using the command-line interface. Moreover, some ICCMA solvers focus on (...) the ICCMA tracks, and do not implement algorithms for other problems. In this paper we describe pygarg, a Python implementation of the SAT-based approach used in the argumentation solver CoQuiAAS. Contrary to CoQuiAAS and most of the participants to the various editions of ICCMA, pygarg incorporates all problems that have been considered in the main track of any edition of ICCMA. We show how to easily use pygarg via a command-line interface inspired by ICCMA competitions, and then how it can be used in other Python scripts as a third-party library. (shrink)

Blair articulates a concept of argument that suggests, as he puts it, that argument is a normative concept (Blair, Informal Logic 24:137–151, 2004, p. 190). Put roughly, the idea is that a collection of propositions doesn’t constitute an argument unless some taken together constitute a reason for the remaining proposition and thereby support it enough to provide at least prima facie justification for it (Blair, in: Blair, Johnson, Hansen, Tindale (eds) Informal Logic at 25, Proceedings of the 25th anniversary conference, (...) Ontario Society for the Study of Argumentation, 2003, p.173). My primary task in this paper is to advance an understanding of the illative unit of argument and the reasons associated with it that provides an intuition pump for a normative concept of argument. My aim is to advance a positive consideration in favor of a normative concept of argument that motivates its further development. I take the normative concept of argument I defend here to be in the same ballpark as the one Blair characterizes. (shrink)

Derek Parfit influentially defends reductionism about persons, the view that a person’s existence just consists in the existence of a brain and body, and the occurrence of a series of physical and mental events. Yet some critics, particularly Mark Johnston, have raised powerful objections to Parfit’s reductionism. In this paper, I defend reductionism against Johnston. In particular, I defend a radical form of reductionism that Buddhist philosophers developed. Buddhist reductionism can justify key features of Parfit’s position, such as the claims (...) that personal identity is not what matters and can also be indeterminate. Furthermore, Buddhist reductionism can avoid Johnston’s objections to Parfit’s reductionism. I conclude that reductionists have good reasons to favor Buddhist reductionism over Parfit’s version.

Over 1.3 billion people in the world are challenged to access good and cheap healthcare when become ill. Health insurance policies are a fantastic strategy to assist people who can't afford medical care. For middle- and low-income nations, there hasn't been much research on the ability to pay for health insurance for public employees like school teachers. Therefore, this cross-sectional questionnaire based research has been undertaken to explore the reflection of health insurance among 383 Bangladeshi school teachers of 5 divisional (...) city center primary school and were being surveyed online between 1st August to 30th August 2022. According to survey, monthly average (mean) health expenditure of respondents were 7668.93 BDT (Bangladeshi Taka equivalent to $80.72) with 95% confidence interval. Of 35% responders suffered from high blood pressure, approximately 8% people were suffering from arthritis and asthma, 7.8% people have heart disease and 8.1 % people suffer from cholesterol problem. Maximum respondents (80%) agreed that health insurance is burden for them. About 51% teachers had no idea about health insurance. However, there was no significant relation in between educational status and health insurance perception for male and female teacher respondents. Moreover, the comparative data highlighted that more awareness and more exploration might be needed in health insurance perception for primary school teachers. This result can contribute to form people’s choice-oriented health insurance policy. (shrink)

Recent advances in human brain organoid systems have raised serious worries about the possibility that these in vitro ‘mini‐brains’ could develop sentience, and thus, moral status. This article considers the relative moral status of sentient human brain organoids and research animals, examining whether we have moral reasons to prefer using one over the other. It argues that, contrary to common intuitions, the wellbeing of sentient human brain organoids should not be granted greater moral consideration than the wellbeing of nonhuman research (...) animals. It does so not by denying that typical humans have higher moral status than animals, but instead by arguing that none of the leading justifications for granting humans higher moral status than nonhuman animals apply to brain organoids. Additionally, it argues that there are no good reasons to be more concerned about the well‐being of human brain organoids compared to those generated from other species. (shrink)

In this article, in an attempt to analyze the crisis caused by the images of imported plastic waste, we consider the relationship between waste and its meaning in the case of geographical dislocation and de- and re-contextualization processes. Our analysis is guided by two recent concepts: The Wasteocene and semiocide. While the Wasteocene clarifies the signifying mechanisms of this period, semiocide allows us to understand which signs, under what conditions, are rendered invisible or disregardable. In coining the concept of semiocide, (...) Ivar Puura emphasized two key features of the phenomenon. Following this distinction, which is based on (un)intentionality, semiocide refers either to a fully conscious, perhaps even hostile, attempt to destroy a semiotic configuration, or to a completely nonconscious, unaware process in which the unawareness itself is the source of the destruction. Although a more cultural approach dominates in Puura’s assertion of the concept, the concept is applicable to human classification, interpretation and transformation of nature (Maran, 2013; Tønnessen et al., 2015). Focusing on the case of Adana as a recent example of a global waste crisis, our aim is to provide a (bio)semiotic framework for assessing how and under what conditions plastic materials become arbiters of environmental and political crises. With heaps of plastic garbage with foreign names on them, the discourse of recycling, restricted media coverage, public indignation, the struggles of environmentalist organizations, and the encounter of different spatio-temporalities, our study aims to convey an impoverished narrative of a city in the south of Türkiye.

In his Ecolinguistics, Stibbe (2020) declares the story of economic growth (the continuous increase in production and consumption) as the ‘master narrative’ that is at the same time the most harmful story we live by. This paper explains where this story of growth comes from and describes how it supplants or suppresses alternatives, such as stories of thrift and sharing. By connecting the biosemiotic model of Funktionskreis (e.g. Uexküll, 1920) as “the primary mechanism of meaning making” (Kull 2020) to cognitive (...) linguistics (e.g. Lakoff, 2009) and critical discourse analysis (e.g. van Leeuwen, 2018), this paper explores how stories of thrift and sharing can be turned into activism that seeks to reframe waste as surplus that can be shared; but they can also hide the old business models of the master narrative. Stories of sharing are often erased to protect corporate interests. Narratives of sharing can be duplicitous, especially in the context of the ‘sharing economy’. Attempts at reframing resources and energy as common wealth owned by everyone are squelched by the master narrative in contexts like resource and energy distribution. Can the new story of shrinking and degrowth become a new alternative to the master narrative and promote new decelerated semiotic habits (Maran, 2023) for a more fulfilling life with less (e.g. Herrmann 2022)?

Based on Kolchinsky and Wolpert’s work on the semantics of autonomous agents, I propose an application of Mathematical Logic and Probability to model cognitive processes. In this work, I will follow Bateson’s insights on the hierarchy of learning in complex organisms and formalize his idea of applying Russell’s Type Theory. Following Weaver’s three levels for the communication problem, I link the Kolchinsky–Wolpert model to Bateson’s insights, and I reach a semantic and conceptual hierarchy in living systems as an explicative model (...) of some adaptive constraints. Due to the generality of Kolchinsky and Wolpert’s hypotheses, I highlight some fundamental gaps between the results in current Artificial Intelligence and the semantic structures in human beings. In light of the consequences of my model, I conclude the paper by proposing a general definition of knowledge in probabilistic terms, overturning de Finetti’s Subjectivist Definition of Probability.

The present paper will summarise the methodology, the scientific outcomes, and the potential for generalisation of the model of a project that studied cohabitation between human inhabitants and liminal species (in the present case, corvids) in Tartu, Estonia, from October 2021 to July 2023, with a comparative field study in Paris, France.

Michael Marder in Dump Philosophy claims that that there has been so much dumping with modern civilization that we now live in a dump, with those parts of our environment not contaminated by dumping, now rare. The growth of the dump is portrayed as the triumph of nihilism, predicted by Nietzsche as the outcome of life denying Neoplatonist metaphysics. Marder’s proposed solution, characterized as “undumping”, is to accept the dump and to promote reinterpretations and informal communities within the dump. It (...) is argued here that Marder provides great insight into our current situation and its causes; however, his proposed solution is too weak. To respond to the situation described, it is argued, it is necessary to distinguish between healthy and unhealthy dumping, or more broadly, healthy and unhealthy participation in nature. To make this distinction, it is necessary see humans as ecosystems and components of ecosystems, including the global ecosystem, as these have been characterized by anti-reductionist ecologists. Ecosystems can be healthy or unhealthy. Dumping and dumps should be identified as problematic outputs when they damage the health of ecosystems. The products of human activity not destined to be consumed or used for further productive activity, can then be identified and judged according to whether they augment or damage ecosystems’ health. Dumping should be severely restricted. This should be associated with making a commitment to life and its value, and living to augment life, developing the social and economic forms and institutions that facilitate living in this way.

This review admires Michael Marder’s inquiry as a parallel for which biosemiotics can find points of conceptual resonance, even as methodological differences remain. By looking at the dump of ungrounded semiosis – the semiotics of dislocating referents from objects, and its effects – we can better do the work of applying biosemiotics not just towards the wonders of living relations, but also to the manifold ways in which industrial civilization is haphazardly yet systematically destroying the possibility for spontaneous yet contextualized (...) semiogenesis. Biosemiotics has much to gain by understanding the ways, gross and subtle, in which Anthropocenic hubris undercuts our own ability to make sense of the world, doubling down on overconfidence at the expense of meaning-making.

This article applies some conceptual tools from semiotics to better understand the disastrous impacts of the world economy on global ecology. It traces the accelerating production of material disorder and waste to the logic of the money sign, as economic production processes simultaneously increase exchange-values and entropy. The exchange of indexical and iconic signs is essential to the dynamics of ecological systems and the proliferation of biological diversity. The human species has added a third kind of sign, the symbol, and (...) more recently a fourth: all-purpose money. Money does not refer to any referent either through contiguity, similarity, or convention. It is an empty sign, capable of assuming any significance that its owner attributes to it. The article argues that the concept of symbolic reference should be restricted to cultural and linguistic phenomena. Money qualifies as a new species of sign based on its exceedingly open mode of reference. It does not refer to any object by social convention but owes its specific properties precisely to the absence of such conventions. The logic of money pivots on decontextualisation: it presupposes and encourages the detachment of exchange values, people, and concepts from the particular and the local. Selective advantage is no longer primarily about calibration within local contexts, but increasingly a matter of transcending or emancipating oneself from the specific. This drift toward decontextualisation reverses the evolution of complexity and diversity throughout the planetary biosphere. (shrink)

In our target article, “Learning and the evolution of conscious agents” we outlined an evolutionary approach to consciousness, arguing that the evolution of a form of open-ended, representational, and generative learning (unlimited associative learning, UAL) drove the evolution of consciousness. Our view highlights the dynamics and functions of consciousness, delineates its taxonomic distribution and suggests a framework for exploring its developmental and evolutionary modifications. The approach we offer resonates with biosemioticians’ views, but as the responses to our target article show, (...) our proposal also faces challenges and has led to suggestions that extend, develop and qualify it. Our response to the 14 varied and rich commentaries starts with the recurring and deep question raised by many of them – the relation between life and sentience. We explore this question by introducing and expanding on “vivaciousness”, a term we coined to describe the turbulent, flexible exploration-stabilization processes inherent in the living condition, as well as addressing the related concepts of Umwelt and selfhood. We then consider the question of the adequacy of unlimited associative learning (UAL) as an evolutionary transition marker (ETM) of minimal consciousness (rather than as a marker of a complex form of sentience), and the possible precursors of sentience. The engagement with these broad themes is entangled with a discussion of evolutionary transitions, constitutive emergence and the function/s of consciousness. The suggestions of our commentators, urging us to explore new concepts and new avenues of research within the framework of a richer view of evolution are then discussed. We end by briefly considering what we regard as a conceptual lacuna, which is leading to the indiscriminate use of the term “sentience” and which awaits further investigation. (shrink)

This article reviews the edited volume “Evolvability: A Unifying Concept in Evolutionary Biology?” through biological and philosophical lenses. The book provides diverse angles on evolvability, which is affected by various hierarchical levels, timescales, and types of variation, thus moving beyond a purely genomics perspective. Evolvability is important to biosemiotics because understanding the dynamics of topological genotype spaces could help one better comprehend the phenotypic spaces of meaning, as developmental codes and interrelations can influence the emergence of biological novelty over time. (...) This book is successful in provoking thought on evolvability's role as both a product and a driver of evolutionary innovations and explores the philosophical implications of how evolution has the capacity to generate novel forms of meaning.
