Which nonhuman animals experience conscious pain?1 This question is central to the debate about animal welfare, as well as being of basic interest to scientists and philosophers of mind. Nociception—the capacity to sense noxious stimuli—is one of the most primitive sensory capacities. Neurons functionally specialized for nociception have been described in invertebrates such as the leech Hirudo medicinalis and the marine snail Aplysia californica (Walters 1996). Is all nociception accompanied by conscious pain, even in relatively primitive animals such as Aplysia, (...) or is it the case, as some philosophers continue to maintain, that conscious experiences are the exclu- sive province of human beings? What philosophical and scientific resources are presently available for assessing claims lying between these extremes? (shrink)

Ethicists have commonly appealed to science to bolster their arguments for elevating the moral status of nonhuman animals. I describe a framework within which I take many ethicists to be making such appeals. I focus on an apparent gap in this framework between those properties of animals that are part of the scientific consensus, and those to which ethicists typically appeal in their arguments. I will describe two different ways of diminishing the appearance of the gap, and argue that both (...) of them present challenges to ethicists seeking a firm scientific basis for their claims about the moral status of animals. I argue that more clarity about the role of appeals to science by applied ethicists leads to questions about the effectiveness of such appeals, and that these questions might best be pursued empirically.

Physical cognition involves a host of cognitive abilities that enable understanding and manipulation of the physical world. Corvids, the bird family that includes crows, ravens and jays, are renowned for their cognitive abilities, but still little is known about their folk physics. This thesis explores the origins of physical cognition in corvids by investigating its mechanisms, development,fitness value and phylogeny in a wide context that includes theoretical and empirical studies.String pulling is a valuable paradigm for addressing these questions. Many animals (...) can pull a string with food attached to its end, but uncovering the cognitive abilities involved in this behaviour requires further testing. Paper I reviews the string-pulling paradigm, which is one of the oldest tests of animal cognition.It is a highly suitable test for species comparisons, socio-ecological correlations, and phylogenetic questions. Paper II tests several corvids, apes and peafowl on a string-pulling task where the first pulls do not result in the food moving closer. Despite the absence of such visual feedback, most subjects pulled strings in completely, although corvids appeared to choose randomly.Tool use is the archetypical example of physical cognition. Many corvids are remarkably adept at using tools in experimental settings. Paper III reviews animal tool use in general. It is now clear that customary tool-using species do not necessarily outperform their non-tool-using relatives on tests of physical cognition. For corvids that frequently use tools in the wild, such as New Caledonian crows and‘Alalā, tool use appears to have a significant fitness value and may have resulted in morphological adaptations. Paper IV describes a novel tool-use mode in New Caledonian crows. They inserted sticks into objects and then moved away,thereby transporting both. One crow could not grasp the target object, which suggests that such insert-and-transport tool use facilitates control over unwieldy objects. Paper V briefly argues that some corvids have shown the ability to make novel causal interventions, although this question should be addressed in a clearer theoretical framework that makes testable predictions.Sensorimotor cognition is a set of fundamental cognitive abilities that enables the integration of sensory and motor information into practical behaviour. It underlies much of corvid physical cognition. Paper VI investigates the development of sensorimotor cognition in ravens. Their skills developed rapidly and exceeded those of some mammals. They reached the same final sensorimotor stage as great apes, albeit at a markedly accelerated rate. The propensity of corvids to cache objects was investigated in Paper VII. Ravens, which often cache food,frequently cached objects, but surprisingly at similar rates as non-food-caching jackdaws. New Caledonian crows mostly cached objects that resembled functional tools.Anthropomorphism is the attribution of human traits to animals. Fear of mistakenly anthropomorphising animals has resulted in biased principles and an uneven burden of proof, which may hinder scientific progress more than it is supposed to offer protection against making mistakes. Cognitive zoology should not be misguided by overcompensating for such potential pitfalls. (shrink)

In recent discussions, it has been argued that a theory of animal rights is at odds with a liberal abortion policy. In response, Francione (1995) argues that the principles used in the animal rights discourse do not have implications for the abortion debate. I challenge Francione’s conclusion by illustrating that his own framework of animal rights, supplemented by a relational account of moral obligation, can address the moral issue of abortion. I first demonstrate that Francione’s animal rights position, which grounds (...) moral consideration in sentience, is committed to the claim that a sentient fetus has a right to life. I then illustrate that a fully developed account of animal rights that recognizes the special obligations humans have to assist animals when we cause them to be dependent and vulnerable through our voluntary actions or omissions is committed to the following: a woman also has a special obligation to assist a sentient fetus when she causes it to be dependent and vulnerable through her voluntary actions or omissions. From these considerations, it will become evident that a fully developed and consistent animal rights ethic does in fact have implications for the abortion discussion. (shrink)

A common Western assumption is that animals cannot be persons. Even in animal ethics, the concept of personhood is often avoided. At the same time, many in cognitive ethology argue that animals do have minds, and that animal ethics presents convincing arguments supporting the individual value of animals. Although “animal personhood” may seem to be an absurd notion, more attention needs to placed on the reasons why animals can or cannot be included in the category of persons. Of three different (...) approaches to personhood—the perfectionist approach, the humanistic approach, and the interactive approach—the third approach is the strongest. Personhood defined via interaction opens new doors for animal ethics. (shrink)

The marker approach is taken as best practice for answering the distribution question: Which animals are conscious? However, the methodology can be used to increase confidence in animals many presume to be unconscious, including C. elegans, leading to a trilemma: accept the worms as conscious; reject the specific markers; or reject the marker methodology for answering the distribution question. I defend the third option and argue that answering the distribution question requires a secure theory of consciousness. Accepting the hypothesis all (...) animals are conscious will promote research leading to secure theory, which is needed to create reliable consciousness tests for animals and AIs. Rather than asking the distribution question, we should shift to the dimensions question: How are animals conscious? (shrink)

Rémi Tison Dans cet article, je traite de la nature des processus cognitifs sous-tendant nos attributions d’états mentaux aux animaux non humains. Selon la conception traditionnelle, nous n’avons qu’un accès indirect aux états mentaux d’autrui, qui doivent être inférés sur la base du comportement. Cette conception traditionnelle influence autant les débats conceptuels concernant l’esprit des animaux que les recherches empiriques sur la cognition animale. Or de récents travaux sur la cognition sociale humaine avancent plutôt une conception « interactionniste », selon (...) laquelle les états mentaux peuvent parfois être directement perçus dans le comportement. J’applique dans cet article la conception interactionniste à l’attribution d’états mentaux aux animaux. Je conclus que celle-ci rend mieux compte des attitudes du sens commun à l’égard des états mentaux des animaux et est plus féconde pour la recherche empirique sur la cognition animale que la conception traditionnelle.

As I assume to begin with, animals with a high level of consciousness, are those beings which are more dependent on their materialistic ecological circumstances than those with less cognition. The most obvious support for this factual claim is the yet still unofficial unit of geological time named the Anthropocene Epoch demarcating human devastation of earthly resources, whereby there is no doubt which species on earth is the most materially dependent. Notwithstanding, we need to keep things quantitively in perspective. Of (...) the 545.8 gigatons of biomass on Earth of which most is plants, animals make up 0.47% while humans only 0.01%, bacteria reigns supreme with 12.8% of total. (shrink)

Philosophical attention to animals can be found in a wide range of texts throughout the history of philosophy, including discussions of animal classification in Aristotle and Ibn Bâjja, of animal rationality in Porphyry, Chrysippus, Aquinas and Kant, of mental continuity and the nature of the mental in Dharmakīrti, Telesio, Conway, Descartes, Cavendish, and Voltaire, of animal self-consciousness in Ibn Sina, of understanding what others think and feel in Zhuangzi, of animal emotion in Śāntarakṣita and Bentham, and of human cultural uniqueness (...) in Xunzi. In recent years, there has been increased attention to animal minds in philosophical discussions across many areas of metaphysics, epistemology, and value theory. Given that nonhuman animals share some biological and psychological features with humans, and that we share community, land, and other resources, consideration of nonhuman animals has much to contribute to our philosophical activities. -/- Contemporary philosophy of animal minds often also engages with the sciences of animal cognition and behavior. The science of comparative cognition is a thriving area of research, complementing the philosophical study in two ways. For one, philosophers of animal cognition can use claims resulting from animal cognition studies as premises in philosophical discussions. For example, Jacob Beck (2012) relies on pigeons’ abilities to compare quantities to argue for nonconceptual content; Sidney Carls-Diamante (forthcoming) appeals to octopus behavior and physiology to defend embodied cognition; Richard Moore (2016a) refers to ape gestural communication to rethink the requirements for intentional communication; Andrew Barron and Colin Klein (2016) appeal to insect cognition research to defend new theories of consciousness; Sarah Vincent, Rebecca Ring, and Kristin Andrews (2019) cite dolphins’ social practices to argue for the existence of norms that do not require metacognition. -/- In addition, philosophers of animal cognition can examine the epistemology and methods used to justify the claims that arise from the science. Research into animal cognition has resulted in surprising claims about animal capacities, such as sociality in garter snakes (Skinner & Miller 2020), tool-use in ants (Maák et al. 2017), mirror self-recognition in fish (Kohda et al. 2019), empathy in rats (Bartal et al. 2011), social learning in fruit flies (Danchin et al. 2018), episodic memory in dogs (Fugazza et al. 2020), addition and subtraction in bees (Howard et al. 2019). How should we evaluate such claims? -/- Some philosophers have argued that animal cognition research is held to a higher standard than human cognition research, and that scientists working with animals are sometimes asked to solve skeptical problems (Halina 2015). Others have challenged scientific assumptions about the relationship between brain size and intelligence, as well as biases against invertebrates (Mikhalevich & Powell 2020). -/- Animal cognition research challenges philosophers to consider that many capacities and behaviors often assumed to require language, sophisticated technological capacities, or legal systems may in fact be had by other animals who lack these properties. In this way, animal cognition research often surprises us by showing that sophisticated-looking activity can be caused through rather simple mechanisms. -/- 1. What is Animal Cognition? 2.

External descriptions, which approach animals via external mechanisms rather than internal mental states, have gained a prominent position. However, according to strong objectivism, attention needs to be placed on the presumptions that lay behind given beliefs. When applied to the topic of animal minds, it reveals that perhaps inter-nal rather than external descriptions would offer a fruitful option. This claim is sup-ported by the Wittgensteinian criticism of skepticism, which seeks to avoid “deflection” and brings forward an “affective stance”. Still, in (...) order to avoid relativ-ism and conservatism, internal descriptions and the affective stance need to place em-phasis on the epistemological ramifications behind beliefs concerning animal minds, and centralise the animal as the reference point of inquiry.

The prolific discussion about consciousness has resulted a multiplicity in the uses for the term. The -curious- little clarity regarding the use of the notion, can lead to confusion to who tries to enter the contemporary discussion of the philosophy of mind. The purpose of this article is to serve as a starting point for those who seek to enter the contemporary discussion of consciousness, presenting: i) the central concept of the consciousness that is used, and ii) give an account (...) of the state of the discussion, that is, the central problem of consciousness.

Arguing in support of Aristotle, Aquinas conceptualised the cognitive functioning of the human as exceeding that of other animals. In its base form, the Thomistic position asserts that the intellective functioning of the human animal is superior to the instinctual operation of the non-human animal. For Aquinas, it is the intellect that determines the enactment of the human will. Thus, if a non-human animal is devoid of intellect, no willing of any action is possible. Consequently, an action of a non-human (...) animal which is humanly perceived as immoral, is in fact morally agnostic because the animal lacks the reasoning capacity to judge the potential action's moral status. Given that Aquinas’ argument centres on the role of reason in determinations of moral status, we seek to determine the status theoria of the Thomistic moral theory in light of contemporary studies into animal cognition. The assertion is made that this particular aspect of Aquinas’ moral theory requires rewriting because reason is evident in animal cognition to a greater extent than Aquinas would have been able to appreciate given his contextual limitations. This presence of reason, we argue, ascribes moral status to some non-human animals, analogous to their human counterparts. However, we will also contend that rather than dismissing Aquinas’ reason-founded ethics, value could be found in retaining a rewritten Thomistic theoretical construction which extends Aquinas’ ethic to include animals apart from the human that are bearers of the faculty of reason.
