Animal Minds, Misc

Information and Meaning are present everywhere around us and within ourselves. Specific studies have been implemented in order to link information and meaning: - Semiotics - Phenomenology - Analytic Philosophy - Psychology No general coverage is available for the notion of meaning. We propose to complement this lack by a systemic approach to meaning generation.

Biosemiotics and Semiotics have similarities and differences. Both deal with signal and meaning. One difference is that Biosemiotics covers a domain (life) that is less complex that the one addressed by Semiotics (human). We believe that this difference can be used to have Biosemiotics bringing added value to Semiotics. This belief is based on the fact that a theory of meaning is easier to build up for living elements than for humans, and that the results obtained for life can make (...) available some tools for a higher level of complexity. Semiotic has been encountering some difficulties to deliver a scientific theory of meaning that can be efficient at the level of human mind. The obstacles come from our ignorance on the nature of human. As it is true that we do not understand the nature of human mind on a scientific basis. On the other hand, the nature and properties of life are better understood. And we can propose a modelization for a generation of meaningful information in the field of elementary life. Once such a modelization is established, it is possible to look at extending it to the domain of human life. Such an approach on a theory of meaning (begininig in Biosemiotics and aiming at Semiotics), is what we present in this paper. Taking an elementary living element as reference, we introduce the bases of a systemic theory of meaning. Using a simple living system submitted to a constraint, we define a meaningful information, a meaning generator system and some elements related to meaningful information transmission. We then try to identify the hypothesis that need to be taken into account so the results obtained for living elements can be extended to human. (shrink)

Information and meaning exist around us and within ourselves, and the same information can correspond to different meanings. This is true for humans and animals, and is becoming true for robots. We propose here an overview of this subject by using a systemic tool related to meaning generation that has already been published (C. Menant, Entropy 2003). The Meaning Generator System (MGS) is a system submitted to a constraint that generates a meaningful information when it receives an incident information that (...) has a relation with the constraint. The content of the meaningful information is explicited, and its function is to trigger an action that will be used to satisfy the constraint of the system. The MGS has been introduced in the case of basic life submitted to a "stay alive" constraint. We propose here to see how the usage of the MGS can be extended to more complex living systems, to humans and to robots by introducing new types of constraints, and integrating the MGS into higher level systems. The application of the MGS to humans is partly based on a scenario relative to the evolution of body self-awareness toward self-consciousness that has already been presented (C. Menant, Biosemiotics 2003, and TSC 2004). The application of the MGS to robots is based on the definition of the MGS applied to robots functionality, taking into account the origins of the constraints. We conclude with a summary of this overview and with themes that can be linked to this systemic approach on meaning generation. (shrink)

A growing literature argues that animals can act for moral reasons without being responsible. I argue that the literature often fails to maintain a clear distinction between moral behavior and moral agency, and I formulate a dilemma: either animals are less moral or they are more responsible than the literature suggests. If animals can respond to moral reasons, they are responsible according to an influential view of moral responsibility–Quality of Will. But if they are responsible, as some argue, costly implications (...) must be acknowledged. If, however, they should not be considered responsible, then we may have to reassess the meaning of animal morality. I discuss ways to eschew responsibility or to tailor it to animals and argue that each requires a revised conception of animal morality. (shrink)

In the mid-nineteenth century, the house sparrow ( Passer domesticus) was introduced to the United States, quickly spreading across the country. For a brief period in the late nineteenth and early twentieth centuries, the observation of sparrow behavior was something of an urban pastime. Traits such as intelligence, reason, persistence, and craftsmanship were conferred onto sparrows by American urbanites. This paper argues that sparrow intelligence was often conflated with domestication: the ability of the birds to adapt to living alongside humans. (...) Praise for the ingenuity of sparrows generally revolved around their nest building, particularly when such structures overcame the challenges posed by urban infrastructure and technology. Sparrows were far less praiseworthy when they caused electricity outages or contaminated water supplies. The sparrow in the United States demonstrates how the relationship between these anecdotes and their implications for animal minds was mediated by the technology and infrastructure of cities. Admirers of sparrows were not measuring the birds’ mental capacity, but rather their ability to adapt to human habitations. Sparrows were only granted intelligence once they had demonstrated their ability to become domesticated. (shrink)

Helmuth Plessner’s philosophical anthropology is framed by a comprehensive theory of living nature. Central to this philosophical biology is the claim that animals lack self-consciousness but their awareness of their surroundings is nevertheless anchored in a self. Since Plessner does not explain how this unselfconscious self is manifest to the animal, the warrant for his claim remains unclear. Following Plessner’s construal of human existence as a radically transformed variant of animal life, I argue that he leaves animals’ selfhood unaccounted for (...) because he overlooks the animal precursor of the feeling of pleasure and displeasure, which affords a pre-reflective self-awareness. I fill this lacuna by drawing on Kant’s and Plessner’s theories of human feelings, Hans Jonas’s conception of animal emotion,and recent arguments that make evaluative affects fundamental to animal consciousness. Revised along these lines, Plessner’s framework allows us to specify how animal affectivity is transformed in self-conscious human life. (shrink)

Anscombe famously argues that to act intentionally is to act under a description, and that “it is the agent's knowledge of what he is doing that gives the descriptions under which what is going on is the execution of an intention.” Further, she takes ‘knows’ to mean that the agent can give these descriptions herself. It would seem to follow that animals cannot act intentionally. However, she denies this, insisting that although animals cannot express intentions, they can have them. But (...) how can we speak without equivocation of humans and animals acting intentionally while maintaining that linguistic expressibility is an essential characteristic of only human action? The human capacity for articulation, I argue, transforms animal intention in the following way: Whereas animal intentions are immanent in their behavior, human action is an actualization of the power to make judgments about what is to-be-done; this confers on human intentions a distinctive sort of independence from behavior.

This open access book revises Kant’s ethical thought in one of its most notorious respects: its exclusion of animals from moral consideration. The book gives readers in animal ethics an accessible introduction to Kant’s views on our duties to others, and his view that we have only ‘indirect’ duties regarding animals. It then investigates how one would have to depart from Kant in order to recognise that animals matter morally for their own sake. Particular attention is paid to Kant’s ‘Formula (...) of Humanity,' the role of autonomy and the moral law, as well as Kant’s notions of practical reason and animal instinct. The result is a deliberately amended version of Kantianism which nevertheless remains faithful to central aspects of Kant’s thought. The book’s final part illustrates the framework’s use in applied contexts, addressing the issues of using animals as mere means, the ethics of veganism and vegetarianism, and environmental protection. Nico Dario Müller shows how, when furnished with duties to animals, Kant's moral philosophy can be a powerful resource for animal ethicists. (shrink)

Like many others, I see Crump et al. (2022) as a milestone for improving upon previous guidelines and for extending their framework to decapod crustaceans. Their proposal would benefit from a firm evolutionary foundation by adding the comparative measurement of life-history complexity as a ninth criterion for attributing sentience to nonhuman animals.

Recent research on bacteria and other microorganisms has provided interesting insights into the nature of life, cooperation, evolution, individuality or species. In this paper, I focus on the capacity of bacteria to produce molecules that are usually classified as ’signals’ and I defend two claims. First, I argue that certain interactions between bacteria should actually qualify as genuine forms of communication. Second, I use this case study to revise our general theories of signaling. Among other things, I argue that a (...) plausible requirement for a state to qualify as a signal is that it is a minimal cause. (shrink)

Chastain and Sawyer, among others, claim that direct cognitive relations can be initiated in evidence cases. Direct cognitive relations will here include Chastain’s knowledge-of and Sawyer’s trace-based acquaintance, as well as related notions such as having-in-mind and singular thought. Against this controversial claim, it is often objected that such cases are better understood as cases of inference rather than cases of direct thought. When one detects something by its footprint, the objection goes, one merely infers that it exists rather than (...) thinking of it directly. The goal of this paper is to analyze what is meant by the inference objection and consider several possible responses to it. Ultimately, I will not offer a knock-down argument against the inference explanation; in fact, I’ll try to explain why I suspect one isn’t possible. Instead, I’ll appeal to the possibility of misdescription and analogous cases involving non-human animals to show that the inference explanation is less plausible than the account to which it provides an alternative.

Despite an increase in research examining maternal and infant touch, and documenting its public health impact, this mode of interaction has historically been omitted from related fields of developmental research in human and non‐human primates. The broad aim of this review is to examine to what extent mother–infant touch has been included in relational paradigms and research. We argue that although theoretical and empirical scholarship on attachment and maternal sensitivity conceptualizes touch as fundamental to caregiver–infant interactions and child development more (...) broadly, touch is rarely operationalized or measured in caregiver–infant interaction paradigms or clinical interventions. Data from primarily human, but also non‐human, primates are reviewed to document the importance of touch, and clinical research is reviewed to document the formal use of touch in human attachment and sensitivity research and intervention. The review closes with recommended directions for future research and related implications. (shrink)

De acordo com a interpretação mais comum na literatura filosófica, Donald Davidson – que celebremente afirmou que “uma criatura não pode ter pensamentos a menos que tenha uma linguagem” – nega que criaturas não linguísticas são criaturas pensantes. No entanto, neste artigo argumento que esta interpretação é errada. Analisando atentamente os argumentos de Davidson, procuro mostrar que ele não está a argumentar que criaturas não linguísticas não podem possuir pensamentos; em vez disso, defendo que ele está simplesmente a afirmar que (...) na ausência de linguagem as atribuições de pensamento não podem ser vistas como mais do que meras ficções úteis que permitem explicar com êxito o comportamento daquelas criaturas.

According to Hutto and Satne, 521–536, 2015), an “essential tension” plagues contemporary neo-Pragmatist accounts of mental contents: their explanation of the emergence and constitution of intentional mental contents is circular. After identifying the problem, they also propose a solution: what neo-Pragmatists need to do, to overcome circularity, is to appeal to a primitive content-free variety of intentionality, different from the full-blown intentionality of propositional attitudes. In this paper, I will argue that, in addition to the problem of circularity, there is (...) another important problem that both neo-Pragmatist accounts, and Hutto and Satnes’s refinement of them, should also deal with: their difficulty to accommodate a host of recent empirical evidence and theoretical developments on the interdisciplinary field of animal cognition. I will call this difficulty the objection from animal minds, and I will present several arguments designed to show that, even though the notion of primitive intentionality, introduced by Hutto and Satne, may be useful to account for some of the most basic ways of dealing with the environment of nonhuman animals, it falls short of providing an adequate explanation of the full-range of cognitive capacities and behavioral dispositions that many animal species display. Thus, their proposal ends up being insufficient to help neo-Pragmatist approaches to overcome the problem of animal minds. Finally, I will suggest that overcoming this objection requires attributing to non-human animals some basic, yet content involving, kinds of intentional mental states. (shrink)

In this essay I explore the resources Thomas Aquinas provides for enquiries concerning the psychological abilities of nonhuman animals. I first look to Aquinas’s account of divine, angelic, human, and nonhuman animal naming, to help us articulate the contours of a ‘critical anthropocentrism’ that aims to steer clear of the mistakes of a na¨ıve anthropocentrism and misconceived avowals to entirely eschew anthropocentrism. I then address the need for our critical anthropocentrism both to reject the mental-physical dichotomy endorsed by ‘folk psychology’ (...) and to articulate a more adequate ‘commonsense psychology’ that acknowledges most embodied animal behavior is observable psychological behavior. Next, I argue that we can develop Aquinas’s doctrine of estimation and conation to formulate an account of nonhuman animal action that more adequately characterizes the purposeful behaviors of nonhuman animals. To do so, we first need to recognize a wider range of nonhuman animal behaviors that are captured by Aquinas’s ‘estimative sense’, and that all of these behaviors are specified by a finite variety of particular goods confined to the animals’ environmental niches. But we also need to supplement Aquinas’s account of human and nonhuman animal agency by exploring the ontogeny and ecology of how humans and other animals become attuned to affordances within these different environmental niches. I argue that we should look to Aquinas’s account of nonhuman animal capacities in ST I-II 6-17 for subtle insights that can expand our understanding of how nonhuman animals engage in purposeful behavior by exercising analogous nonrational and imperfectly voluntary forms of intention, deliberation, choice, execution, and enjoyment. I conclude with an outline for how future enquiry can seek to explain the nonrational purposeful problem-solving competencies of chimps, canines, corvids, cetaceans, cephalopods, and other nonhuman animal species.

In this commentary on Marino and Merskin's "Intelligence, complexity, and individuality in sheep", I argue that their literature review provides further evidence of the fundamental theoretical shift in psychology towards a non-anthropocentric psychological taxonomy, in which cognitive capacities are classified in a structure that provides an overall understanding of the place of mind (including human minds) throughout nature.

We outline a dual systems approach to temporal cognition, which distinguishes between two cognitive systems for dealing with how things unfold over time – a temporal updating system and a temporal reasoning system – of which the former is both phylogenetically and ontogenetically more primitive than the latter, and which are at work alongside each other in adult human cognition. We describe the main features of each of the two systems, the types of behavior the more primitive temporal updating system (...) can support, and the respects in which it is more limited than the temporal reasoning system. We then use the distinction between the two systems to interpret findings in comparative and developmental psychology, arguing that animals operate only with a temporal updating system and that children start out doing so too, before gradually becoming capable of thinking and reasoning about time. After this, we turn to adult human cognition and suggest that our account can also shed light on a specific feature of our everyday thinking about time that has been the subject of debate in the philosophy of time, which consists in a tendency to think about the nature of time itself in a way that appears ultimately self-contradictory. We conclude by considering the topic of intertemporal choice, and argue that drawing the distinction between temporal updating and temporal reasoning is also useful in the context of characterising two distinct mechanisms for delaying gratification.

While there has been significant philosophical debate on whether nonlinguistic animals can possess conceptual capabilities, less time has been devoted to considering 'talking' animals, such as parrots. When they are discussed, their capabilities are often downplayed as mere mimicry. The most explicit philosophical example of this can be seen in Brandom's frequent comparisons of parrots and thermostats. Brandom argues that because parrots (like thermostats) cannot grasp the implicit inferential connections between concepts, their vocal articulations do not actually have any conceptual (...) content. In contrast, I argue that Pepperberg's work with Alex (and other African grey parrots) provides evidence that the vocal articulations of at least some parrots have conceptual content. Using Frege's insight that numbers assert something about a concept, I argue that Alex's ability to answer the question "How many?" depended upon a prior grasp of conceptual content. Developing this claim, I argue that Alex's arithmetical abilities show that he was capable of using numbers as both concepts and objects. Frege's theoretical insight and Pepperberg's empirical work provide reason to reconsider the capabilities of parrots, as well as what sorts of tasks provide evidence for conceptual content. (shrink)

I defend a Mengzian version of the Social Intelligence Hypothesis, according to which humans think about one another’s beliefs and desires—and reasons for action—in order to solve our social living problems through cooperation, rather than through competition and deception, as the more familiar Machiavellian version has it. Given this framework, and a corresponding view about the function of belief attribution, I argue that while apes need not attribute propositional attitudes to pass the “false belief task,” we should not conclude that (...) apes may be behaviorists. Rather, the Mengzian Social Intelligence Hypothesis perspective offers another interpretation of ape behavior, intermediate between behaviorist and propositional attitude schemas. I argue that the false belief task can be solved by individuals who have an agency schema which takes others to be minded beings who have goals, emotions, and perceptions, but who fail to consider propositional attitudes or reasons for behavior. I then argue that a true test of belief attribution in great apes would be one that shows they seek explanations in terms of reasons for behavior. However, no such test yet exists. (shrink)

Animal welfare scientists face an acute version of the problem of inductive risk, since they must choose whether to affirm attributions of mental states to animals in advisory contexts, knowing their decisions hold consequences for animal welfare. In such contexts, the burden of proof should be sensitive to the consequences of error, but a framework for setting appropriate burdens of proof is lacking. Through reflection on two cases—pain and cognitive enrichment—I arrive at a tentative framework based on the principle of (...) expected welfare maximization. I then discuss the limitations of this framework and the questions it leaves open. (shrink)

The theory-theory of human uniqueness posits that the capacity to theorize, in a way strongly analogous to theorizing in scientific practice, was a key innovation in the hominid lineage and was responsible for many of our unique cognitive traits. One of the central arguments that its proponents have used to support the claim that animals are not theorists, the logical problem, bears strong similarities to Hempel's theoretician's dilemma, which purports to show that theories are unnecessary. This similarity threatens to undermine (...) both the claim that theorizing serves a unique, adaptive role in human cognition and our ability to test for the presence of theories. I examine two historical responses to the theoretician's dilemma and argue that they open up strategies for experimentally testing for theoretical ability in other animals. (shrink)

The rise of physicalism and naturalism, the development of cognitive science, and the explosion and popularization of knowledge about animal behavior has brought us to see that most of the properties that were once thought to distinguish humans from other animals are shared with other animals. Many people now see properties that are morally relevant to how it is permissible to treat animals, such as sentience, as widely distributed. Agency, however, is one area in which the retreat from human uniqueness (...) is halting. In this essay I suggest that we should feel the same pressure to bring together accounts of human and animal agency that we feel with respect to sentience and other such characteristics. I go on to diagnose the resistance, and briefly sketch how things might look if we were to see agency as continuous. (shrink)

The previous studies have shown that human infants and domestic dogs follow the gaze of a human agent only when the agent has addressed them ostensively—e.g., by making eye contact, or calling their name. This evidence is interpreted as showing that they expect ostensive signals to precede referential information. The present study tested chimpanzees, one of the closest relatives to humans, in a series of eye-tracking experiments using an experimental design adapted from these previous studies. In the ostension conditions, a (...) human actor made eye contact, called the participant’s name, and then looked at one of two objects. In the control conditions, a salient cue, which differed in each experiment (a colorful object, the actor’s nodding, or an eating action), attracted participants’ attention to the actor’s face, and then the actor looked at the object. Overall, chimpanzees followed the actor’s gaze to the cued object in both ostension and control conditions, and the ostensive signals did not enhance gaze following more than the control attention-getters. However, the ostensive signals enhanced subsequent attention to both target and distractor objects (but not to the actor’s face) more strongly than the control attention-getters—especially in the chimpanzees who had a close relationship with human caregivers. We interpret this as showing that chimpanzees have a simple form of communicative expectations on the basis of ostensive signals, but unlike human infants and dogs, they do not subsequently use the experimenter’s gaze to infer the intended referent. These results may reflect a limitation of non-domesticated species for interpreting humans’ ostensive signals in inter-species communication. (shrink)

In the late eighteenth and early nineteenth centuries, philosophers including Kant and Hegel draw a sharp distinction between the human and the animal. The human is self-conscious, the animal is not; the human has moral worth, the animal does not. By the mid to late nineteenth century, these claims are widely rejected. As scientific and philosophical work on the cognitive and motivational capacities of animals increases in sophistication, many philosophers become suspicious of the idea that there is any divide between (...) human beings and other animals. This paper traces the transitions in eighteenth- and nineteenth-century thought about animals. My focal point is the notion of drive or instinct (Trieb, Instinkt). Although in sporadic usage during earlier times, the drive concept explodes in the eighteenth and nineteenth centuries. It begins playing central roles in three distinct areas: embryology, ethology, and metaphysics. In embryology, drive describes a force, inaccessible in itself but whose results are visible and susceptible to scientific and philosophical study, governing organic development. In ethology, drives are the sources of seemingly deliberate, highly articulated, yet non-conscious activities, which are directed at ends of which the animal is ignorant. In metaphysics, drive describes the human essence. I focus on the way in which the emergence of the drive concept in each of these three domains undermines the idea that there is any sharp distinction between the human and the animal. I conclude by considering how, in light the collapse of the human/animal divide, ethical theories are reshaped. (shrink)

Peña-Guzmán (2017) argues that empirical evidence and evolutionary theory compel us to treat the phenomenon of suicide as continuous in the animal kingdom. He defends a “continuist” account in which suicide is a multiply-realizable phenomenon characterized by self-injurious and self-annihilative behaviors. This view is problematic for several reasons. First, it appears to mischaracterize the Darwinian view that mind is continuous in nature. Second, by focusing only on surface-level features of behavior, it groups causally and etiologically disparate phenomena under a single (...) conceptual umbrella, thereby reducing the account’s explanatory power. Third, it obscures existing analyses of suicide in biomedical ethics and animal welfare literatures. A more promising naturalistic approach might seek a theoretical understanding of the social/ecological circumstances that drive humans and perhaps other animals to self-destruction. (shrink)

Although brain size and the concept of intelligence have been extensively used in comparative neuroscience to study cognition and its evolution, such coarse-grained traits may not be informative enough about important aspects of neurocognitive systems. By taking into account the different evolutionary trajectories and the selection pressures on neurophysiology across species, Logan and colleagues suggest that the cognitive abilities of an organism should be investigated by considering the fine-grained and species-specific phenotypic traits that characterize it. In such a way, we (...) would avoid adopting human-oriented, coarse-grained traits, typical of the standard approach in cognitive neuroscience. We argue that this standard approach can fail in some cases, but can, however, work in others, by discussing two major topics in contemporary neuroscience as examples: general intelligence and brain asymmetries.

Traditionally, discussions of moral participation – and in particular moral agency – have focused on fully formed human actors. There has been some interest in the development of morality in humans, as well as interest in cultural differences when it comes to moral practices, commitments, and actions. However, until relatively recently, there has been little focus on the possibility that nonhuman animals have any role to play in morality, save being the objects of moral concern. Moreover, when nonhuman cases are (...) considered as evidence of moral agency or subjecthood, there has been an anthropocentric tendency to focus on those behaviors that inform our attributions of moral agency to humans. For example, some argue that the ability to evaluate the principles upon which a moral norm is grounded is required for full moral agency. Certainly, if a moral agent must understand what makes an action right or wrong, then most nonhuman animals would not qualify (and perhaps some humans too). However, if we are to understand the evolution of moral psychology and moral practice, we need to turn our attention to the foundations of full moral agency. We must first pay attention to the more broadly normative practices of other animals. Here, we begin that project by considering evidence that great apes and cetaceans participate in normative practices. (shrink)

Cognitive abilities cannot be measured directly. What we can measure is individual variation in task performance. In this paper, we first make the case for why we should be interested in mapping individual differences in task performance on to particular cognitive abilities: we suggest that it is crucial for examining the causes and consequences of variation both within and between species. As a case study, we examine whether multiple measures of inhibitory control for non-human animals do indeed produce correlated task (...) performance; however, no clear pattern emerges that would support the notion of a common cognitive ability underpinning individual differences in performance. We advocate a psychometric approach involving a three-step programme to make theoretical and empirical progress: first, we need tasks that reveal signature limits in performance. Second, we need to assess the reliability of individual differences in task performance. Third, multi-trait multi-method test batteries will be instrumental in validating cognitive abilities. Together, these steps will help us to establish what varies between individuals that could impact their fitness and ultimately shape the course of the evolution of animal minds. Finally, we propose executive functions, including working memory, inhibitory control and attentional shifting, as a sensible starting point for this endeavour. (shrink)

Since the question “Do chimpanzees have a theory of mind?” was raised in 1978, scientists have attempted to answer it, and philosophers have attempted to clarify what the question means and whether it has been, or could be, answered. Mindreading or theory of mind refers to the ability to attribute mental states to other individuals. Some versions of the question focus on whether chimpanzees engage in belief reasoning or can think about false belief, and chimpanzees have been given nonverbal versions (...) of the false belief moved-object task. Other versions of the question focus on whether chimpanzees understand what others can see, and chimpanzees can pass those tests. From this data, some claim that chimpanzees know something about perceptions, but nothing about belief. Others claim that chimpanzees do not understand belief or perceptions, because the data fails to overcome the “logical problem,” and permits an alternative, non-mentalistic interpretation. I will argue that neither view is warranted. Belief reasoning in chimpanzees has focused on examining false belief in a moved object scenario, but has largely ignored other functions of belief. The first part of the paper is an argument for how to best understand belief reasoning and offers suggestion for future investigation. The second part of the paper addresses and diffuses the “logical problem.” I conclude that chimpanzees may reason about belief, but that there is already compelling evidence that they reason about perceptions.

Personhood is not a redundant category, but a social cluster kind. On this view, chimpanzees have their own kind of personhood profile. Seeing that chimpanzees have a personhood profile allows us to argue that chimpanzees like Tommy are individuals who deserve rights under the law. If chimpanzee personhood is a matter of public policy that needs to be decided by society, then learning more about the person profiles of chimpanzees will be essential in making this case. As the public learns (...) what scientists have come to see, and with public conversations about what counts as a person, our society can make another ethical transformation that will be recognized by the courts. But without the metaphysical personhood concept to rely on, we will have a difficult time showing that chimpanzees should count as persons under the law. (shrink)

While philosophers have been interested in animals since ancient times, in the last few decades the subject of animal minds has emerged as a major topic in philosophy. _The Routledge Handbook of Philosophy of Animal Minds_ is an outstanding reference source to the key topics, problems and debates in this exciting subject and is the first collection of its kind. Comprising nearly fifty chapters by a team of international contributors, the _Handbook_ is divided into eight parts: Mental representation Reasoning and (...) metacognition Consciousness Mindreading Communication Social cognition and culture Association, simplicity, and modeling Ethics. Within these sections central issues, debates and problems are examined, including: whether and how animals represent and reason about the world; how animal cognition differs from human cognition; whether animals are conscious; whether animals represent their own mental states or those of others; how animals communicate; the extent to which animals have cultures; how to choose among competing models and explanations of animal behavior; and whether animals are moral agents and/or moral patients; The Routledge Handbook of Philosophy of Animal Minds is essential reading for students and researchers in philosophy of mind, philosophy of psychology, ethics and related disciplines such as ethology, biology, psychology, linguistics and anthropology.

A surge of empirical research demonstrating flexible cognition in animals and young infants has raised interest in the possibility of rational decision-making in the absence of language. A venerable position, which I here call “Classical Inferentialism”, holds that nonlinguistic agents are incapable of rational inferences. Against this position, I defend a model of nonlinguistic inferences that shows how they could be practically rational. This model vindicates the Lockean idea that we can intuitively grasp rational connections between thoughts by developing the (...) Davidsonian idea that practical inferences are at bottom categorization judgments. From this perspective, we can see how similarity-based categorization processes widely studied in human and animal psychology might count as practically rational. The solution involves a novel hybrid of internalism and externalism: intuitive inferences are psychologically rational (in the explanatory sense) given the intensional sensitivity of the similarity assessment to the internal structure of the agent's reasons for acting, but epistemically rational (in the justificatory sense) given an ecological fit between the features matched by that assessment and the structure of the agent's environment. The essay concludes by exploring empirical results that show how nonlinguistic agents can be sensitive to these similarity assessments in a way that grants them control over their opaque judgments.

Empirical studies of the social lives of non-human primates, cetaceans, and other social animals have prompted scientists and philosophers to debate the question of whether morality and moral cognition exists in non-human animals. Some researchers have argued that morality does exist in several animal species, others that these species may possess various evolutionary building blocks or precursors to morality, but not quite the genuine article, while some have argued that nothing remotely resembling morality can be found in any non-human species. (...) However, these different positions on animal morality generally appear to be motivated more by different conceptions of how the term “morality” is to be defined than by empirical disagreements about animal social behaviour and psychology. After delving deeper into the goals and methodologies of various of the protagonists, I argue that, despite appearances, there are actually two importantly distinct debates over animal morality going on, corresponding to two quite different ways of thinking about what it is to define “morality”, “moral cognition”, and associated notions. Several apparent skirmishes in the literature are thus cases of researchers simply talking past each other. I then focus on what I take to be the core debate over animal morality, which is concerned with understanding the nature and phylogenetic distribution of morality conceived as a psychological natural kind. I argue that this debate is in fact largely terminological and non-substantive. Finally, I reflect on how this core debate might best be re-framed. (shrink)

Explanations of animal problem-solving often represent our choices as limited to two: first, we can explain the observed behavior as a product of trained responses to sensory stimuli, or second, we can explain it as due to the animal’s possession of general rules utilizing general concepts. My objective in this essay is to bring to life a third alternative, namely, an explanation in terms of imagistic cognition.The theory of imagistic cognition posits representations that locate objects in a multidimensional similarity space. (...) It proposes that an animal’s expectations can be explained on the basis of the similarity of novel objects to objects previously encountered.The animal can predict the behavior of the novel object by producing a mental movie of the novel object by morphing it into an object, the behavior of which has previously been observed. After criticizing the theory of concept abstraction, I will identify some of the key elements of imagistic cognition.Then I will attempt to illustrate the utility of this conception of cognition by using it to explain the combination of successes and failures observed in monkeys in tool- mediated retrieval tasks (Fujita et al. 2003; Fujita et al. 2011) and in great apes in trap tube and trap table experiments (Martin-Ordas et al. 2008; Martin-Ordas et al. 2012).

Conwy Lloyd Morgan (1852–1936) is widely regarded as the father of modern comparative psychology. Yet, Morgan initially had significant doubts about whether a genuine science of comparative psychology was even possible, only later becoming more optimistic about our ability to make reliable inferences about the mental capacities of non-human animals. There has been a fair amount of disagreement amongst scholars of Morgan’s work about the nature, timing, and causes of this shift in Morgan’s thinking. We argue that Morgan underwent two (...) quite different shifts of attitude towards the proper practice of comparative psychology. The first was a qualified acceptance of the Romanesian approach to comparative psychology that he had initially criticized. The second was a shift away from Romanes’ reliance on systematizing anecdotal evidence of animal intelligence towards an experimental approach, focused on studying the development of behaviour. We emphasize the role of Morgan’s evolving epistemological views in bringing about the first shift – in particular, his philosophy of science. We emphasize the role of an intriguing but overlooked figure in the history of comparative psychology in explaining the second shift, T. Mann Jones, whose correspondence with Morgan provided an important catalyst for Morgan’s experimental turn, particularly the special focus on development. We also shed light on the intended function of Morgan’s Canon, the methodological principle for which Morgan is now mostly known. The Canon can only be properly understood by seeing it in the context of Morgan’s own unique experimental vision for comparative psychology. (shrink)

One particularly vibrant area of debate, in recent times, concerning potential cognitive differences between humans and other animals (and also one wth a veritable history) is centred on the claim that non-human animals are, in some sense, 'stuck in time', whereas humans are able to cognitively transcend the present moment in time by turning their minds back to particular past events. This chapter seeks to clarify what is at issue in these debates.

Because we humans speak a public language, there has always been a special reason to suppose that we have a language of thought. For nonhuman animals, this special reason is missing, and the issue is less straightforward. On the one hand, there is evidence of various types of nonlinguistic representations, such as analog magnitude representations, which can explain many types of intelligent behavior. But on the other hand, the mere fact that some aspects of animal cognition can be explained by (...) nonlinguistic representations hardly suffices to show that animal minds are bereft of any sentence-like representations. This paper explores these complexities and argues that empirical research into the logical abilities of nonhuman animals provides a more direct way of evaluating whether they have a language of thought. Along the way, I offer a novel suggestion of how the hypothesis that animals draw disjunctive syllogisms can be empirically distinguished from the hypothesis, defended by Michael Rescorla, that animals reason probabilistically in accordance with Bayes’ Law.

Behavioural flexibility is often treated as the gold standard of evidence for more sophisticated or complex forms of animal cognition, such as planning, metacognition and mindreading. However, the evidential link between behavioural flexibility and complex cognition has not been explicitly or systematically defended. Such a defence is particularly pressing because observed flexible behaviours can frequently be explained by putatively simpler cognitive mechanisms. This leaves complex cognition hypotheses open to ‘deflationary’ challenges that are accorded greater evidential weight precisely because they offer (...) putatively simpler explanations of equal explanatory power. This paper challenges the blanket preference for simpler explanations, and shows that once this preference is dispensed with, and the full spectrum of evidence—including evolutionary, ecological and phylogenetic data—is accorded its proper weight, an argument in support of the prevailing assumption that behavioural flexibility can serve as evidence for complex cognitive mechanisms may begin to take shape. An adaptive model of cognitive-behavioural evolution is proposed, according to which the existence of convergent trait–environment clusters in phylogenetically disparate lineages may serve as evidence for the same trait–environment clusters in other lineages. This, in turn, could permit inferences of cognitive complexity in cases of experimental underdetermination, thereby placing the common view that behavioural flexibility can serve as evidence for complex cognition on firmer grounds.

Could animals behave morally if they can’t mindread? Does morality require mindreading capacities? Moral psychologists believe mindreading is contingently involved in moral judgements. Moral philosophers argue that moral behaviour necessarily requires the possession of mindreading capacities. In this paper, I argue that, while the former may be right, the latter are mistaken. Using the example of empathy, I show that animals with no mindreading capacities could behave on the basis of emotions that possess an identifiable moral content. Therefore, at least (...) one type of moral motivation does not require mindreading. This means that, a priori, non-mindreading animals can be moral. (shrink)

A prevailing view is that while human communication has an ‘ostensive-inferential’ or ‘Gricean’ intentional structure, animal communication does not. This would make the psychological states that support human and animal forms of communication fundamentally different. Against this view, I argue that there are grounds to expect ostensive communication in non-human clades. This is because it is sufficient for ostensive communication that one intentionally address one’s utterance to one’s intended interlocutor – something that is both a functional pre-requisite of successful communication (...) and cognitively undemanding. Furthermore, while ostension is an important feature of intentional communication, the inferences required in Gricean communication may be minimal: ostension and inference may come apart. The grounds for holding that animal communication could not be Gricean are therefore weak. I finish by defending the idea that a ‘minimally Gricean’ model of communication is a valuable tool for characterising the communicative interactions of many animal species. (shrink)

The ability to engage in reflexive thought—in thought about thought or about other mental states more generally—is regarded as a complex intellectual achievement that is beyond the capacities of most nonhuman animals. To the extent that reflexive thought capacities are believed necessary for the possession of many other psychological states or capacities, including consciousness, belief, emotion, and empathy, the inability of animals to engage in reflexive thought calls into question their other psychological abilities. This chapter attacks the idea that reflexive (...) thought is required in this pervasive way and holds that supposing that it is derives from a tendency among philosophers and scientists toward overcomplication. Against this tendency, it recommends an aponoian framework, from apó, “away from” and noûs, “intelligence” or “thought,” arguing that seemingly complex psychological abilities are often not as complex as they seem, and do not require the ability to engage in reflexive thought.

I think there is something to be said in a positive and constructive vein about collective intentionality in non-human animals. Doing so involves probing at the concept of collective intentionality fairly directly (Section 2), considering the various forms that collective intentionality might take (Section 3), showing some sensitivity to the history of appeals to that concept and its close relatives (Section 4), and raising some broader questions about the relationships between sociality, cognition, and institutions by discussing two different possible cases (...) of collective intentionality in non-human animals: that of the social insects (Section 5) and that of highly social mammals, such as canines (Section 6). If the discussion here is on track, then the widely shared perspective on collective intentionality exemplified by the work of Searle and Tomasello needs to be reconsidered. (shrink)

on ). Advice about how to move forward on the mindreading debate, particularly when it comes to overcoming the logical problem, is much needed in comparative psychology. In chapter 4 of his book Ockham’s Razors, Elliott Sober takes on the task by suggesting how we might uncover the mechanism that mediates between the environmental stimuli that is visible to all, and chimpanzee social behavior. I argue that Sober's proposed method for deciding between the behaivor-reading and mindreading hypotheses fails given the (...) nature of each of those hypotheses. I argue that the behavior-reading hypothesis that Povinelli and colleagues propose is so rich and robust that it is going to make predictions that are behaviorally indiscernible from the mindreading hypothesis. Further, I argue that the logical problem artificially separates one’s knowledge of behavior and one’s knowledge of mind. If we reject this form of dualism, the logical problem doesn’t arise.

We provide an account of chimpanzee-specific agency within the context of philosophy of action. We do so by showing that chimpanzees are capable of what we call reason-directed action, even though they may be incapable of more full-blown action, which we call reason-considered action. Although chimpanzee agency does not possess all the features of typical adult human agency, chimpanzee agency is evolutionarily responsive to their environment and overlaps considerably with our own. As such, it is an evolved set of capacities (...) for goal-directed behavior, which solves problems that chimpanzees naturally encounter. Thus, it ought not be understood as a deficient instance of human agency. (shrink)

Lurz and Krachun propose a new experimental protocol designed to discriminate genuine mindreading animals from mere behavior-readers and to give evidence in favor of the claim that chimpanzees are capable of attributing internal goals to others. They suggest that chimpanzees' variety of "internal goal attribution" consists in attributing to others basic intentional representations, baptized by Millikan as "pushmi-pullyu representations". Now, Millikan distinguishes what I propose to call 'pure' PPs from more complex varieties of PPs, which allow their owners to respond (...) more flexibly to their environments. But, what would happen if we tried to differentiate, analogously, between more or less sophisticated mind-readers in virtue of the sorts of PPs that they could attribute to others? What would attributing complex PPs consist in and how would such capacity increase the predictive powers of chimpanzee mind-readers? This paper offers an answer to these questions. Based on Millikan's work, I differentiate two varieties of complex PPs. Then, I examine what a basic mind-reader, only capable of attributing 'pure' PPs, would be able to do. After that, I distinguish two more sophisticated varieties of mindreading, each consisting in the attribution of one of the complex PPs previously presented, and I show how the ability to attribute complex PPs to others comes with more potent and flexible capacities to anticipate their behavior. Finally, I offer some reasons to think that attributing complex PPs is still simpler than full-blown mindreading and I briefly evaluate the prospects of extending this proposal to infant social cognition.
