Ever since John Leslie Mackie’s ‘popularization’ of moral error theories in meta-ethics, increasing attention has been focused on how to escape the force of nihilism. For many opponents of the moral error theory, ‘moral nihilism’ is used as a derogatory synonym associated with immorality and selfishness, but such a defamatory usage of the label is obviously not very helpful for a serious philosophical examination of the view. The goal of this paper is to draw on insights by David Hume and other Humean philosophers such as J.L. Mackie, Richard Joyce, and Richard Garner, in order to turn ‘moral nihilism’ from a term of abuse to a ‘badge of honour’.

In this paper we argue that physical strength is in philosophical terms best understood as general agentive ability to exercise difficult physical effort. We develop this metaphysical claim about strength, by focusing on the historically developed most paradigmatic test of overall strength: The sport of Strong (Wo)Man. We extract the understanding of strength present in this sport, and show how the current philosophical agents' abilities, and physical effort, lend themselves to capture the essential features of strength, providing the justification for our claim. Finally we argue that strongman itself is already surprisingly well thought through to assess strength, balancing different tradeoffs that exist when quantitatively attempting to measure strength, making it a robust epistemic tool to determine strength in an interdisciplinary manner.

What is the role of consciousness in nature? The science of consciousness has largely neglected the question through its emphasis on human experience. In this précis of A Philosophy for the Science of Animal Consciousness, I outline how we can move from a top-down approach that begins with investigations in humans to an evolutionary bottom-up approach that targets the adaptive origins of even the most minimal forms of subjective experience. I will also offer an introduction to the central thesis of the book, i.e. the pathological complexity thesis, according to which consciousness evolved in order to enable animals to adaptively respond to their life history challenges.

The axiom of transitivity has been challenged in economic theorizing for over seventy years. Yet, there does not seem to be any movement in economics towards removing classical rational choice models from introductory microeconomics books. The concept of rationality has similarly been employed in the cognitive sciences and biology, and yet, transitivity has here not only been shown to be violated, but also rationally so. Some economists have thus responded with attempts to develop alternative theories that give up on the axiom of transitivity. In this paper, I argue that there is a conceptual confusion in this debate that rests on the mistaken idea that there is something like the “one true theory of rationality” that can determine axioms like transitivity to be true or false. Instead, I defend a shift towards a pluralism of concepts of rationality as well as models in which transitivity should play a role depending on the purposes of the model at hand.

In the last two decades, there has been a blossoming literature aiming to counter the neglect of plant capacities. In their recent paper, Miguel Segundo-Ortin and Paco Calvo begin by providing an overview of the literature to then question the mistaken assumptions that led to plants being immediately rejected as candidates for sentience. However, it appears that many responses to their arguments are based on the implicit conviction that because animals have far more sophisticated cognition and agency than plants, and that plants should not have the same moral status as animals, plants should not have any moral status. Put in simpler terms: it is not as bad to eat plants than to eat, say, pigs. While there are still uncertainties around comparative moral and policy implications between animals and plants, given a gradualist account of quasi-sentience and partial moral status, both of which we claim are a matter of degree, we may not have to abolish our convictions by declaring that plants have no sentience or moral status at all. Indeed, we can hold two things at the same time: that animals and plants have moral status, but animals have prima facie more moral status than plants.

This paper aims to articulate an anarchist challenge to a widespread assumption in the rapidly growing philosophical literature on models, modeling-practices, and model-based science. I argue that the various entities and practices called “models” and “modeling-practices” are too heterogeneous, too context-sensitive, and serve too many scientific purposes and roles, as to constitute unified scientific phenomena that would allow for useful epistemic and ontologies analyses. Just like Feyerabend once argued that there are no general useful inferences to be drawn about the method of “science”, I argue that the same lesson will apply to “model-based science”, hence calling my view model anarchism.

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.

Synthetic meat made from animal cells will transform how we eat. It will reduce suffering by eliminating the need to raise and slaughter animals. But it will also have big public health benefits if it becomes widely consumed. In this paper, we discuss how “clean meat” can reduce the risks associated with intensive animal farming, including antibiotic resistance, environmental pollution, and zoonotic viral diseases like influenza and coronavirus. Since the most common objection to clean meat is that some people find it “disgusting” or “unnatural,” we explore the psychology of disgust to find possible counter-measures. We argue that the public health benefits of clean meat give us strong moral reasons to promote its development and consumption in a way that the public is likely to support. We end by depicting the change from farmed animals to clean meat as a collective action problem and suggest that social norms rather than coercive laws should be employed to solve the problem.

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.

This goal of this thesis in the philosophy of nature is to move us closer towards a true biological science of consciousness in which the evolutionary origin, function, and phylogenetic diversity of consciousness are moved from the field’s periphery of investigations to its very centre. Rather than applying theories of consciousness built top-down on the human case to other animals, I argue that we require an evolutionary bottomup approach that begins with the very origins of subjective experience in order to make sense of the place of mind in nature. To achieve this goal, I introduce and defend the pathological complexity thesis as both a framework for the scientific investigation of consciousness and as a lifemind continuity thesis about the origins and function of consciousness.

This book attempts to advance Donald Griffin's vision of the "final, crowning chapter of the Darwinian revolution" by developing a philosophy for the science of animal consciousness. It advocates a Darwinian bottom-up approach that treats consciousness as a complex, evolved, and multidimensional phenomenon in nature rather than a mysterious all-or-nothing property immune to the tools of science and restricted to a single species. The so-called emergence of a science of consciousness in the 1990s has at best been a science of human consciousness. This book aims to advance a true Darwinian science of consciousness in which its evolutionary origin, function, and phylogenetic diversity are moved from the field’s periphery to its very centre, thus enabling us to integrate consciousness into an evolutionary view of life. Accordingly, this book has two objectives: (i) to argue for the need and possibility of an evolutionary bottom-up approach that addresses the problem of consciousness in terms of the evolutionary origins of a new ecological lifestyle that made consciousness worth having and (ii) to articulate a thesis and beginnings of a theory of the place of consciousness as a complex evolved phenomenon in nature that can help us to answer the question of what it is like to be a bat, an octopus, or a crow. A Philosophy for the Science of Animal Consciousness will appeal to researchers and advanced students interested in advancing our understanding of animal minds as well as anyone with a keen interest in how we can develop a science of animal consciousness.

Interdisciplinary research is becoming more and more popular. Many funding bodies encourage interdisciplinarity, as a criterion that promises scientific progress. Traditionally this has been linked to the idea of integrating or unifying disciplines. Using evolutionary game theory as a case study, Till Grüne-Yanoff (2016) argued that there is no such necessary link between interdisciplinary success and integration. Contrary to this, this paper argues that evolutionary game theory is a genuine case of successful integration between economics and biology, shedding lights on the many dimensions along which integration can take place.

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.

In this article, I respond to commentaries by Eva Jablonka and Simona Ginsburg and by David Spurrett on my target article “Complexity and the Evolution of Consciousness,” in which I have offered the first extended articulation of my pathological complexity thesis as a hypothesis about the evolutionary origins and function of consciousness. My reply is structured by the arguments raised rather than by author and will offer a more detailed explication of some aspects of the pathological complexity thesis.
