The field of language evolution has recently made Gricean pragmatics central to its task, particularly within comparative studies between human and non-human primate communication. The standard model of Gricean communication requires a set of complex cognitive abilities, such as belief attribution and understanding nested higher-order mental states. On this model, non-human primate communication is then of a radically different kind to ours. Moreover, the cognitive demands in the standard view are also too high for human infants, (...) who nevertheless do engage in communication. In this paper I critically assess the standard view and contrast it with an alternative, minimal model of Gricean communication recently advanced by Richard Moore. I then raise two objections to the minimal model. The upshot is that this model is conceptually unstable and fails to constitute a suitable alternative as a middle ground between full-fledged human communication and simpler forms of non-human animal communication.

This paper proposes an intermediate account of personhood, based on the capacity to participate in intersubjective interactions. We articulate our proposal as a reply to liberal and restrictive accounts, taking Mark Rowlands’ and Stephen Darwall’s proposals as contemporary representatives of each view, respectively. We argue that both accounts fall short of dealing with borderline cases and defend our intermediate view: The criteria of personhood based on the second-person perspective of mental state attribution. According to it, a person should be able (...) to participate in intersubjective interactions. We apply our proposal to the borderline cases of non-human primates and human infants. (shrink)

Social norms – rules governing which behaviours are deemed appropriate or inappropriate within a given community – are typically taken to be uniquely human. Recently, this position has been challenged by a number of philosophers, cognitive scientists, and ethologists, who have suggested that social norms may also be found in certain non-human animal communities. Such claims have elicited considerable scepticism from norm cognition researchers, who doubt that any non-human animals possess the psychological capacities necessary for normative cognition. (...) However, there is little agreement among these researchers about what these psychological prerequisites are. This makes empirical study of animal social norms difficult, since it is not clear what we are looking for and thus what should count as behavioural evidence for the presence (or absence) of social norms in animals. To break this impasse, we offer an approach that moves beyond contested psychological criteria for social norms. This approach is inspired by the animal culture research program, which has made a similar shift away from heavily psychological definitions of ‘culture’ and to become organized around a cluster of more empirically tractable concepts of culture. Here, we propose an analogous set of constructs built around the core notion of a normative regularity, which we define as a socially maintained pattern of behavioural conformity within a community. We suggest methods for studying potential normative regularities in wild and captive primates. We also discuss the broader scientific and philosophical implications of this research program with respect to questions of human uniqueness, animal welfare and conservation. (shrink)

The last decades have seen major advances in the study of gestures both in humans and non-human primates. In this paper, we seriously examine the idea that there may be gestural form types that are shared across great ape species, including humans, which may underlie gestural universals, both in form and meaning. We focus on one case study, the hand fling gesture common to chimpanzees and humans, and provide a semantic analysis of this gesture.

This paper develops the situational model of primate beliefs from the Prior-Lurz line of thought. There is a strong skepticism concerning primate beliefs in the analytic tradition which holds that beliefs have to be propositional and non-human animals do not have them. The response offered in this paper is twofold. First, two arguments against the propositional model as applied to other animals are put forward: an a priori argument from referential opacity and an empirical argument from varieties of working (...) memory. Second, the Prior-Lurz situational model based on state of affairs as opposed to propositions is introduced and defended with two significant modifications. With this model of primate beliefs we can make progress in understanding how other primates can have certain mindreading capacity. (shrink)

Conducting research on animals is supposed to be valuable because it provides information on how human mechanisms work. But for the use of animal models to be ethically justified, it must be epistemically justified. The inference from an observation about an animal model to a conclusion about humans must be warranted for the use of animals to be moral. When researchers infer from animals to humans, it’s an extrapolation. Often non-human primates are used as animal models in (...) laboratory behavioral research. The target populations are humans and other non-human primates. I argue that the epistemology of extrapolation renders the use of non-human primates in laboratory behavioral research unreliable. If the model is relevantly similar to the target, then the experimental conditions introduce confounding variables. If the model is not relevantly similar to the target, then the observations of the model cannot be extrapolated to the target. Since using non-human primates in as animal models in laboratory behavioral research is not epistemically justified, using them as animal models in laboratory behavioral research is not ethically justified.

Humans leverage material forms for unique cognitive purposes: We recruit and incorporate them into our cognitive system, exploit them to accumulate and distribute cognitive effort, and use them to recreate phenotypic change in new individuals and generations. These purposes are exemplified by writing, a relatively recent tool that has become highly adept at eliciting specific psychological and behavioral responses in its users, capability it achieved by changing in ways that facilitated, accumulated, and distributed incremental behavioral and psychological change between individuals (...) and generations. Writing is described here as a self-organizing system whose design features reflect points of maximal usefulness that emerged under sustained collective use of the tool. Such self-organization may hold insights applicable to human cognitive evolution and tool use more generally. Accordingly, this article examines the emergence of the ability to leverage material forms for cognitive purposes, using the tool-using behaviors and lithic technologies of ancestral species and contemporary non-human primates as proxies for matters like collective use, generational sustainment, and the non-teleological emergence of design features.

This paper pursues the idea that human and non-human great apes share a common set of directive (imperative) gestures and their meanings. We investigate gestures that are multifunctional, in that they have different effects in different contexts, focusing on non-human ape gestures that communicate “Stop that” in some contexts, and “Move away” in others. What may superficially appear to be lexical ambiguity can be derived from a single abstract lexical entry, “Not X!”, concluded to be a candidate (...) for a universal building block of meaning, shared by human and non-human great apes, reflections of which may also be found in the pragmatic gestures in humans.

First-person and third-person perspectives are different items of human consciousness. Feeling the taste of a fruit or being consciously part of a group eating fruits call for different perspectives of consciousness. The latter is about objective reality (third-person data). The former is about subjective experience (first-person data) and cannot be described entirely by objective reality. We propose to look at how these two perspectives could be rooted in an evolutionary origin of human consciousness, and somehow be connected. Our (...) starting point is a scenario describing how evolution could have transformed a non self-conscious auto-representation into a conscious self-representation (Menant 2006). The scenario is based on the performance of inter-subjectivity existing among non human primates (Gardenfors 2006). A key item of the scenario is the identification of the auto-representation of a subject with the representations that the subject has of her conspecifics, the latter feeding the former with the meaning: “existing in the environment”. So during evolution, pre-human primates were brought to perceive their auto-representation as existing in the environment. Such process could have generated the initial elements of a conscious self-representation. We take this scenario as providing a possible rooting of human consciousness in evolution. We develop here a part of this scenario by expliciting the inward and outward components of the non self-conscious auto-representation. Inward components are about proprioception and interoception (thirst, pain, …). Outward components cover the sensory information relative to the perception of the body (seen feet, … ) and of its effects on the environment. We consider that the initial elements of a conscious self-representation have been applied to both inward and outward components of the auto-representation. We propose that the application to inward components made possible some first-person information, and that the application to outward components brought up third-person information. Relations between the two perspectives are highlighted. Such approach can root first-person and third-person perspectives in the same slot of human evolution. We conclude by a summary of the above and introduce a possible application of this approach to the concepts of bodily self and of pre-reflexive self-consciousness (Legrand, 2006). (shrink)

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)

Theory of mind, the attribution of mental states to others is one form of social cognition. The aim of this paper is to highlight the importance of another, much simpler, form of social cognition, which I call vicarious representation. Vicarious representation is the attribution of other-centered properties to objects. This mental capacity is different from, and much simpler than, theory of mind as it does not imply the understanding (or representation) of the mental (or even perceptual) states of another agents. (...) I argue that the most convincing experiments that are supposed to show that non-human primates have theory of mind in fact demonstrate that they are capable of vicarious representation. The same is true for the experiments about the theory of mind of infants under 12 months. (shrink)

This paper considers the question of whether chimpanzees possess at least a primitive sense of normativity: i.e., some ability to internalize and enforce social norms—rules governing appropriate and inappropriate behaviour—within their social groups, and to make evaluations of others’ behaviour in light of such norms. A number of scientists and philosophers have argued that such a sense of normativity does exist in chimpanzees and in several other non-human primate and mammalian species. However, the dominant view in the scientific and (...) philosophical literature is that psychological capacities for social norms evolved uniquely in the human lineage, after our last common ancestor with chimpanzees and bonobos. After reviewing some of the existing evidence for normative capacity in chimpanzees, I defend the thesis of chimpanzee normativity against three key theoretical objections that have been presented in the literature, each of which have played a part in motivating the dominant sceptical position. I argue that, while we still have much to learn about the nature and extent of the normative capacities of other animals, there is strong prima facie evidence for social norms and normative evaluation in chimpanzees and the main theoretical objections to chimpanzee normativity are not at all compelling.

A computer can come to understand natural language the same way Helen Keller did: by using “syntactic semantics”—a theory of how syntax can suffice for semantics, i.e., how semantics for natural language can be provided by means of computational symbol manipulation. This essay considers real-life approximations of Chinese Rooms, focusing on Helen Keller’s experiences growing up deaf and blind, locked in a sort of Chinese Room yet learning how to communicate with the outside world. Using the SNePS computational knowledge-representation system, (...) the essay analyzes Keller’s belief that learning that “everything has a name” was the key to her success, enabling her to “partition” her mental concepts into mental representations of: words, objects, and the naming relations between them. It next looks at Herbert Terrace’s theory of naming, which is akin to Keller’s, and which only humans are supposed to be capable of. The essay suggests that computers at least, and perhaps non-human primates, are also capable of this kind of naming. (shrink)

Music and language are universal human abilities with many apparent similarities relating to their acoustics, structure, and frequent use in social situations. We might therefore expect them to be understood and processed similarly, and indeed an emerging body of research suggests that this is the case. But the focus has historically been on the individual, looking at the passive listener or the isolated speaker or performer, even though social interaction is the primary site of use for both domains. Nonetheless, (...) an important goal of emerging research is to compare music and language in terms of acoustics and structure, social interaction, and functional origins to develop parallel accounts across the two domains. Indeed, a central aim of both of evolutionary musicology and language evolution research is to understand the adaptive significance or functional origin of human music and language. An influential proposal to emerge in recent years has been referred to as the social bonding hypothesis. Here, within a comparative approach to animal communication systems, I review empirical studies in support of the social bonding hypothesis in humans, non-human primates, songbirds, and various other mammals. In support of this hypothesis, I review six research fields: (i) the functional origins of music; (ii) the functional origins of language; (iii) mechanisms of social synchrony for human social bonding; (iv) language and social bonding in humans; (v) music and social bonding in humans; and (vi) pitch, tone and emotional expression in human speech and music. I conclude that the comparative study of complex vocalizations and behaviors in various extant species can provide important insights into the adaptive function(s) of these traits in these species, as well as offer evidence-based speculations for the existence of “musilanguage” in our primate ancestors, and thus inform our understanding of the biology and evolution of human music and language.

The evolution from pre-human primates to modern Homo sapiens is a complex one involving many domains, ranging from the material to the social to the cognitive, both at the individual and the community levels. This article focuses on a critical qualitative transition that took place during this evolution involving both the social and the cognitive domains. For the social domain, the transition is from the face-to-face forms of social interaction and organization that characterize the non-human primates (...) that reached, with Pan, a hiatus due to the centripetal effects that highly individualized behavior has on a social system. The transition is to the relation-based forms of social organization that evolved in the hominins ancestral to Homo sapiens and are universal in human societies today. For the cognitive domain, this transition involves going from behavior responding mainly to phenomenal level sensory inputs to behavior formed in accordance with the concept of a relation, initially abstracted from behavior patterns, then extending the concept of a relation beyond abstraction from behavior patterns to the concept of a relation generated recursively through constructing the relation of a relation. This extension made possible the construction of systems of relations; initially genealogical systems of relations constructed culturally using the logic of recursion, and subsequently, the symbolic, computational systems of kin term relations referred to by anthropologists as kinship terminologies. The latter are “constructed realities” in the sense this term is used by cultural anthropologists. It follows that the evolution of relation-based systems of social interaction is not adequately accounted for through population model evolutionary accounts such as the Dual Inheritance Theory of human evolution since “constructed realities” constitute collectively and publicly shared cultural knowledge rather than the individually and privately possessed knowledge that is assumed in the population model framework for human evolution.

DARWIN’s (1859, 1871) discoveries have profound ethical implications that continue to be misrepresented and/or ignored. In contrast to socialdarwinistic misuses of his theory, Darwin was a great humanitarian who paved the way for an integrated scientific and ethical world view. As an ethical doctrine, socialdarwinism is long dead ever since its defeat by E. G. Moore although the socialdarwinistic thought is a hard-die in the biological community. The accusations of sociobiology for being socialdarwinistic are unfounded and stem from the moralistic (...) fallacy that is, a false assumption that morality is good by definition. Both social and developmental psychology demonstrate that the moral agency is a motivational device for executing reciprocity that remains at the core of any morality across all studied societies and throughout the ontogeny of moral judgment. The level of true universalizing ethical reflection (KOHLBERG’s postconvential stages or GIBBS’s existential phase) is achieved by a small minority of humans, thus showing that Homo sapiens is a moral but not an ethical animal. While the origin of reciprocity has been perfectly explained by sociobiology, the evolutionary assembly of affective and cognitive elements that make up the moral agency is being successfully studied by the social/personality/developmental psychology as extended to non-human primates. As DARWIN (1871) expected, the key innovation for the evolution of moral agency was the emergence of empathy that evolved independently at least three times: in elephants, dolphins and primates. Empathy has a motivational power of its own; it is also necessary for moral agency that requires two cognitive abilities: reflective self-consciousness and understanding of causality; the two make possible the attribution of responsibility. All these requirements are met by the chimpanzees whose moral agency operates in dyads. In contrast, the human moral agency allows for a third party intervention that opens up vast opportunities for ideologies, especially religions, to use and misuse the moral agency to enforce a reciprocation that may be harmful to both individuals and the entire group. Also, the moral agency is known to enforce enhanced intragroup cohesion and loyalty in response to conflict and war, which suggests that the two prima facie opposed human universals, morality and warfare, may have coevolved. The most important ethical consequence that follows from the increasing understanding of the primate moral agency is that every received morality is ethically flawed, none can be taken as a paragon of goodness, and each needs corrections by science-informed ethics. In fact, Darwin pioneered the integration of science and ethics, an approach that has come to be appreciated only recently under the heading of consilience. (shrink)

Self-consciousness is a product of evolution. Few people today disagree with the evolutionary history of humans. But the nature of self-consciousness is still to be explained, and the story of evolution has rarely been used as a framework for studies on consciousness during the 20th century. This last point may be due to the fact that modern study of consciousness came up at a time where dominant philosophical movements were not in favor of evolutionist theories (Cunningham 1996). Research on consciousness (...) based on Phenomenology or on Analytic Philosophy has been mostly taking the characteristics of humans as starting points. Relatively little has been done with bottom-up approaches, using performances of animals as a simpler starting point to understand the generation of consciousness through evolution. But this status may be changing, thanks to new tools coming from recent discoveries in neurology. The discovery of mirror neurons about ten years ago (Gallese et al. 1996, Rizzolatti et al. 1996) has allowed the built up of new conceptual tools for the understanding of intersubjectivity within humans and non human primates (Gallese 2001, Hurley 2005). Studies in these fields are still in progress, with discussions on the level of applicability of this natural intersubjectivity to non human primates (Decety and Chaminade 2003). We think that these subject/conspecific mental relations made possible by mirror neurons can open new paths for the understanding of the nature of self-consciousness via an evolutionist bottom-up approach. We propose here a scenario for the build up of self-consciousness through evolution by a specific analysis of two steps of evolution: first step from simple living elements to non human primates comparable to chimpanzees, and second step from these non human primates to humans. We identify these two steps as representing the evolution from basic animal awareness to body self-awareness, and from body self-awareness to self-consciousness. (we consider that today non human primates are comparable to what were pre-human primates). We position body self-awareness as corresponding to the performance of mirror self recognition as identified with chimpanzees and orangutans (Gallup). We propose to detail and understand the content of this body self-awareness through a specific evolutionist build up process using the performances of mirror neurons and group life. We address the evolutionary step from body self-awareness to self-consciousness by complementing the recently proposed approach where self-consciousness is presented as a by-product of body self-awareness amplification via a positive feedback loop resulting of anxiety limitation (Menant 2004). The scenario introduced here for the build up of self-consciousness through evolution leaves open the question about the nature of phenomenal-consciousness (Block 2002). We plan to address this question later on with the help of the scenario made available here. (shrink)

The question about evolution of consciousness has been addressed so far as possible selectional advantage related to consciousness ("What evolutionary advantages, if any, being conscious might confer on an organism ? "). But evidencing an adaptative explanation of consciousness has proven to be very difficult. Reason for that being the complexity of consciousness. We take here a different approach on subject by looking at possible selectional advantages related to the performance of Self Awareness that appeared during evolution millions of years (...) before consciousness as we know it for humans. The interest of such an approach is that the analysis of selectional advantage is done at an evolution step sigificantly simpler that the step of Human Consciousness. We analyse how evolutionary advantages have resulted from this specific Self Awareness step. This is done by taking into consideration the possibility for a subject to identify with a conspecific at this level of evolution. We use the results made available by Mirror Neuron researchs where intersubjectivity and some level of identification with conspecifics have been evidenced for non human primates. Selectional advantages related to Self Awareness are analysed two ways: - Reformulating the performances of imitation and of development of language. - Showing that Self Awareness within group life can naturaly produce an important increase in fear/anxiety for a subject, and that the means implemented by the subject to overcome this fear/anxiety can act as significant evolution advantages opening the road to Human Consciousness. Such approach brings new elements supporting the view that consciousness is grounded in emotions. It also proposes some more evolutionist explanations to the widely dicussed subject of Empathy (S. Preston & F. de Waal) in terms of specific behaviour implemented to limit fear/anxiety increase. This approach also provides some explanation for limited anxiety within dolphins and introduces a basis for a possible phylogenesis of emotions. (shrink)

Numerous evolutionary linguists have indicated that human pointing behaviour might be associated with the evolution of language. At an ontogenetic level, and in normal individuals, pointing develops spontaneously and the onset of human pointing precedes as well as facilitates phases in speech and language development. Phylogenetically, pointing behaviour might have preceded and facilitated the evolutionary origin of both gestural and vocal language. Contrary to wild non-human primates, captive and human-reared nonhuman primates also demonstrate pointing (...) behaviour. In this article, we analyse the debates on pointing and its role it might have played in language evolution from a meta-level. From within an Applied Evolutionary Epistemological approach, we examine how exactly we can determine whether pointing has been a unit, a level or a mechanism in language evolution. (shrink)

This article introduces a special issue on mechanisms in language evolution research. It describes processes relevant for the emergence of protolanguage and the transition thereof to modern language. Protolanguage is one of the key terms in the field of language evolution, used to designate a hypothesised intermediate stage in the emergence of language present in extinct hominins: qualitatively different from non-human primate communication in possessing some, but not all, of the features that characterise modern language. Much debate in language (...) evolution focuses on the exact delineation of these features, as well as the means whereby the transitions occurred: first from non-human primate communication systems to protolanguage, and then from protolanguage to modern language. In what follows, we first propose a comprehensive typology of protolanguage debates, taking into account the postulated structural organisation of protolanguage, its functions, and its communicative modality. This makes it possible to show how a specific focus on mechanisms and processes deemed relevant for the emergence of these features allows us to assess the explanatory scope of the existing theories of protolanguage.

To say Early Confucians advocated the possession of a sense of shame as a means to moral virtue underestimates the tact and forethought they used successfully to mold natural dispositions to experience shame into a system of self, familial, and social governance. Shame represents an adaptive system of emotion, cognition, perception, and behavior in social primates for measurement of social rank. Early Confucians understood the utility of the shame system for promotion of cooperation, and they build and deploy cultural (...) modules – e.g., rituals, titles, punishments – with this in mind. These policies result in subtle alterations to components of the evolved shame system that are detectable in data form contemporary cross-cultural psychology that show that populations in the Confucian diaspora have a unique shame profile compared to Western and non-Western populations. The status of Confucian diaspora populations as outliers in the context of shame is partially explained by appeal to the cultural transmission and historical endurance of relevant Early Confucian cultural modules.

Povinelli’s Problem is a well-known methodological problem confronting those researching nonhuman primate cognition. In this paper I add a new wrinkle to this problem. The wrinkle concerns introspection, i.e., the ability to detect one’s own mental states. I argue that introspection either creates a new obstacle to solving Povinelli’s Problem, or creates a slightly different, but closely related, problem. I apply these arguments to Robert Lurz and Carla Krachun’s (Review of Philosophy and Psychology 2: 449–481, 2011) recent attempt at solving (...) Povinelli’s Problem. (shrink)

Researchers have converged on the idea that a pragmatic understanding of communication can shed important light on the evolution of language. Accordingly, animal communication scientists have been keen to adopt insights from pragmatics research. Some authors couple their appeal to pragmatic aspects of communication with the claim that there are fundamental asymmetries between signalers and receivers in non-human animals. For example, in the case of primate vocal calls, signalers are said to produce signals unintentionally and mindlessly, whereas receivers are (...) thought to engage in contextual interpretation to derive the significance of signals. We argue that claims about signaler-receiver asymmetries are often confused. This is partly because their authors conflate two conceptions of pragmatics, which generate different accounts of the explanatory target for accounts of the evolution of language. Here we distinguish these conceptions, in order to help specify more precisely the proper explanatory target for language evolution research. (shrink)

The goal of this paper is to establish a hierarchical level of deception which does not apply only to humans and non-human animals, but also to the rest of the living world, including plants. We will follow the hierarchical categorization of deception, set forth by Mitchell (1986), in which the first level of deception starts with mimicry, while the last level of deception includes learning and intentionality, usually attributed to primates. We will show how such a hierarchy can (...) be attributed to bacteria, plants, and fungi, see that self-deception is not inherent only to humans, and then connect the evolutionary roots of deception with the philosophical notion of intentionality.

With an extensive amount of research on the social lives of primates, Frans de Waal has been a pioneering advocate for the continuity of human and non-human minds, putting forward the idea that these creatures exhibit rudimentary political and moral behaviors. One of the traits which de Waal focuses on is animal normativity, a set of behaviors functionally defined as adherence to social standards. Recently, some philosophers have endorsed this position, holding that animals show a psychological capacity (...) called normative cognition underlying those and other social behaviors. In this paper, I assess whether advocacy for animal normativity is an exercise of theory construction in comparative cognition. To that end, I present three features of this kind of theory construction. First, the explanatory goal of building functional analyses of cognitive capacities. Second, the conceptual aid of comparative thinking for theory construction. Third, the heuristic value of theory in specifying possible roads of inquiry. Taking these features into account, I assess whether the claims advocates make regarding animal normativity consider them. My answer is negative. First, since some advocates focus on behavioral traits and not on psychological capacities, they are not producing theory in comparative cognition, although, as I argue, they should. Second, there is a disregard for hypothesis testing and no evolutionary considerations to support their views. Finally, the claim that non-human animals exhibit normativity does not seem to have heuristic value. (shrink)

This essay is a Neo-Aristotelian critique of Frans de Waal’s evolutionary moral sentimentalism. For a sentimentalist, moral judgments are rooted in reactive attitudes such as empathy, and De Waal argues that higher primates have the capacity for empathy—they can read other agent’s minds and react appropriately. De Waal concludes that the building blocks of human morality—primarily empathy—are present in primate social behavior. I will engage de Waal from within the sentimentalist tradition itself broadly construed and the Aristotelian virtue (...) tradition more specifically. Within an Aristotelian framework, emotion regulation is necessary for moral responsibility. Aristotle understands that emotions are evaluative perceptions with cognitive content, and non-human animals do not possess the cognitive capacities for emotion regulation and are thus not morally responsible. This marks a boundary between primate behavior and human morality. (shrink)

In this paper, I reject that animal reasoning, negation in particular, necessarily involves the representation of absences, as suggested by Bermúdez (2003, 2006, 2007), since this would still work as a logical negation (unavailable for non-linguistic creatures). False belief, pretense, and communication experiments show that non-human animals (at least some primates) have difficulties representing absent entities or properties. I offer an alternative account resorting to the sub-symbolic similarity judgments proposed by Vigo & Allen (2009) and expectations: animal proto-negation (...) takes place through the incompatibility between an expected and the actual representation. Finally, I propose that the expectation paradigm be extrapolated to other experi-ments in cognitive psychology (both with pre-linguistic children and animals) in order to design fair experiments that test other minds considering their true abilities.

Evolutionary advantages of consciousness and intersubjectivity are part of current philosophical debates on the nature of consciousness. Both are linked and intersubjectivity is sometimes considered as a form of consciousness [1]. Regarding the evolution of consciousness, studies tend to focus on phenomenal consciousness [2]. We would like here to bring the focus on self-consciousness and continue the build up of a corresponding evolutionary scenario. We also propose to introduce a possible evolutionary link between self-consciousness and phenomenal consciousness. Our starting point (...) is the evolutionary scenario based on the evolution of intersubjectivity that goes thru the identification with conspecifics at pre-human primate time frame [3, 4, 5]. The scenario considers that such identification with conspecifics brought the non self-conscious auto-representation carried by our prehuman primate ancestors to merge with the representations of conspecifics. The latter transferred to the auto-representation the characteristics of an entity existing in the environment, and by this way introduced some first elements of self-consciousness for our pre-human ancestors. In addition, an anxiety increase coming from the identification with suffering or endangered conspecifics produced an evolutionary engine based on anxiety limitation. We want here to complement this evolutionary approach by introducing the improvement of action programs as a contributor to the evolutionary advantages of intersubjectivity and self-consciousness. We look at the possibility for a subject to improve the action programs that conspecifics implement. The performance of identification with conspecifics allows the subject to consider that errors made by conspecifics are potentially her own errors, and consequently allows the subject to correct the errors of conspecifics for her own benefit. We describe the process of non successful action identification from the perspective of an observer and present the synergetic action program improvements with their contribution to the evolution of intersubjectivity and self-consciousness. We add this contribution to the existing evolutionary scenario on self-consciousness and introduce a possible evolutionary link between self-consciousness and phenomenal consciousness. We use for that the relation existing between phenomenal consciousness and pre-reflexive self-consciousness [6] and propose to link the latter to the proposed evolutionary nature of self-consciousness. We finish by summarizing the points addressed and by introducing some possible continuations. (shrink)

It is pretty obvious to most of us that self-consciousness is a product of evolution. But its nature is unknown. We propose here a scenario addressing a possible evolutionary nature of self-consciousness covering the segment linking pre-human primates to humans. The scenario is based on evolutions of representations and of inter-subjectivity that could have taken place within the minds of our pre-human ancestors . We begin by situating self-consciousness relatively to other aspects of human consciousness. With (...) the help of anthropology, we date a possible starting point of our scenario at a time when our non self-conscious pre-human ancestors were able to build meaningful representations and were capable of inter-subjectivity, like are our today modern apes. As the proposed scenario is based on an evolution of representations, we recall an existing model for meaningful representations based on the generation of meaningful information by systems submitted to internal constraints. This model allows us to define representations of conspecifics and auto-representations that we assume as having been present in the minds of our pre-human ancestors. The next step of the scenario is to consider an evolution of inter-subjectivity towards identification with conspecifics that could have led to a merger of the auto-representation with the representations of conspecifics in the minds of our ancestors. Such a merger brought the auto-representation to become about an entity existing in the environment, as were the representations of conspecifics. We consider that such identification with conspecifics has introduced in the mind of our ancestors an elementary and embryonic sense of being an existing entity that we name ‘ancestral self-consciousness’. The same process has also imposed to our ancestors an identification with suffering or endangered conspecifics which has produced an important anxiety increase that could have blocked the evolutionary process. We propose that the performances developed by our ancestors to manage that anxiety increase have also generated significant evolutionary advantages that have helped the development of ancestral self-consciousness and favored its evolution toward our full-fledged self-consciousness. It is also proposed that some pre-human primates have avoided the anxiety increase by finding a niche where evolutionary advantages were not necessary. This may have led to our today apes. The contribution of anxiety to the proposed scenario brings to position anxiety management as having guided the evolution of self-consciousness and as still being a key player in our today human minds. Regarding philosophy of mind, possible links between phenomenal consciousness and the proposed nature of self-consciousness are introduced. The conclusion presents a summary of the points addressed here. Possible continuations are highlighted as related to human mind, to anxiety management and to artificial intelligence. (shrink)

At first glance, it looks like Aristotle can’t make up his mind about the ethical or moral status of non-human animals in his ethical treatises. Somewhat infamously, the Nicomachean Ethics claims that “there is neither friendship nor justice towards soulless things, nor is there towards an ox or a horse” (EN 8.11.1161b1–2). Since Aristotle thinks that friendship and justice are co-extensive (EN 8.9.1159b25–32), scholars have often read this passage to entail that humans have no ethical obligations to non-human (...) animals. By contrast, although the Eudemian Ethics denies that non-human animals can participate in “primary” friendships, EE 7.2 claims that “the other kinds of friendship are also found among animals; and it is evident that utility is present to some extent among them both in relation to humankind, in the case of tame animals, and in relation to each other” (EE 7.2.1236b3–11). Does the Nicomachean account of non-human animals contradict that of the Eudemian Ethics? Ultimately, I believe the Nicomachean account is consistent with the Eudemian account. Nonetheless, I argue that Aristotle’s treatment of non-human animals differs significantly in the two texts. My chapter explores this difference in greater detail and considers the ramifications of such a difference for our understanding of Aristotle’s place in the philosophical tradition concerning the ethical status of non-human animals.

Consciousness-based approaches to non-human moral status maintain that consciousness is necessary for (some degree or level of) moral status. While these approaches are intuitive to many, in this paper I argue that the judgment that consciousness is necessary for moral status is not secure enough to guide policy regarding non-humans, that policies responsive to the moral status of non-humans should take seriously the possibility that psychological features independent of consciousness are sufficient for moral status. Further, I illustrate some practical (...) consequences of calling consciousness-based views into question. (shrink)

The scope of the paper is to present the concept of the radical dyad of the “non-human,” in an attempt to think radical humanity in terms of Marxian materialism, which is the product of approaching Marx’s writings on “the real” and “the physical” by way of François Laruelle’s non-philosophical method. Unlike posthumanism, inspired by critical theory and the method of poststructuralism, the theory of the non-human, as a radical dyad of technology in the generic sense of the word (...) (ranging from the techné of speaking a natural language to AI technology) and the organic understood as physicality, does away with anthropocentrism. Moreover, it does away with any anthropomorphology of thought, that is, it does away with any theorizing or philosophy that is centered on the notion of (human) subjectivity or, to borrow a Laruellian term, any “posture of thought” that is molded according to the structure of subjectivity centered thinking.

Ambitious value learning proposals to solve the AI alignment problem and avoid catastrophic outcomes from a possible future misaligned artificial superintelligence (such as Coherent Extrapolated Volition [CEV]) have focused on ensuring that an artificial superintelligence (ASI) would try to do what humans would want it to do. However, present and future sentient non-humans, such as non-human animals and possible future digital minds could also be affected by the ASI’s behaviour in morally relevant ways. This paper puts forward Sentientist Coherent (...) Extrapolated Volition, an alternative to CEV, that directly takes into account the interests of all sentient beings. This ambitious value learning proposal would significantly reduce the likelihood of risks of astronomical suffering from the ASI’s behaviour, and thus we have very strong pro-tanto moral reasons in favour of implementing it instead of CEV. This fact is crucial in conducting an adequate cost-benefit analysis between different ambitious value learning proposals. (shrink)

Traditional Yorùbá culture admits the hegemonic locus that humans rank above all else on the planet. The outlook received decisive ratification several millennia ago in one of the Odùs of their Ifá Corpus. Specifically, in Odù Ògúndá Otura, one of the numerous chapters of the Ifá Corpus, Ọ̀rúnmìlà, the founder and primordial deity of Ifá discloses his authorization, the use of non-human animals for sacrifice and other human ends interminably. In this study, we engage the Ifá chapter that (...) upholds this outlook. We riposte that the age long supercilious perspective among the Yorùbá that humans rank higher and over non-human animals, as documented in the said Odù is no longer tenable on biological and moral-legal grounds. If the biological and moral-legal thrusts are not invalid, what framework is plausible when the interest(s) of non-human animals clash with the interest(s) of Ifá tradition and Yorùbá culture? On what basis will it be appropriate to jettison the interest(s) of the one for the interest(s) of the other? In the light of these posers, we employ Kai Horsthemke’s ethical individualism as the suitable groundwork that considers the interest of animals recommended for sacrifice in Ifá obeisance. (shrink)

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)

Urban residents have the potential to play a key role in helping to facilitate ecological resilience of wilderness areas and ecosystems beyond the city by helping ensure the migration of nonhuman climate refugee populations. Three ethical frameworks related to this issue could determine whether we have an ethical duty to help nonhuman climate refugee populations: ethical individualism, ethical holism, and species ethics. Using each of these frameworks could support the stronger view that policy makers and members of the public have (...) a moral duty to mitigate the impacts of climate induced migration, or the weaker claim that these impacts should be taken into account when making land-use and planning decisions in urban contexts.

In this paper I discuss the role of non-humans in Aquinas’ account of moral learning. I intend to show that the entire created order can play an important role in demonstrating to us the life of virtue, and argue that non-human exemplars offer important advantages to the moral learner. I begin by addressing apparent problems with this approach, founded on the observation that human virtue, for Aquinas, is unique to humans. I resolve these by showing that Aquinas’ approach (...) to exemplars is fundamentally analogical, meaning that exemplars point beyond themselves and need not necessarily live the good life to which they direct learners. I show that this means that Aquinas can use non-humans as moral exemplars and offer examples of him doing just that. Finally, I offer an assessment of the benefits of this approach. Among other things, it offers ethicists new ways to focus on particular virtues and provides a plausible way to include non-humans in the moral realm. (shrink)

This Special Issue is an outcome of the lectures and discussions on ‘Cross-cutting Themes and Concepts in Human Rights’, offered as a Seminar Course to the students of the MA Programme, School of International Studies, Jawaharlal Nehru University. As part of the Course, a Webinar on ‘Rethinking Rights and Justice for Non-Humans’ was held in 2022, in which the participants advanced some of the most compelling arguments for the meaningful representation of non-human entities in law and governance. In (...) the three sessions of the webinar, the participants explored the terrain of relevant concepts, emerging norms, and moral justifications that underline the case of non-human entities: (i) The Limits of Animal Rights: Exploring the Case for Multispecies Justice, (ii) Humanist Dimensions of Machines, and (iii) Representing Nature: Rights, Crimes, and Diplomacy. Scholarly literature on the subject matter sheds light on the gaps in existing legal frameworks concerning the responsibilities of human beings towards non-human life forms. There is evidence of a growing universal consciousness embedded in the worth and sacredness of non-human life forms. A series of developments in the fields of technology, philosophy, and other disciplines have moved non-human entities to the forefront of legal reforms, domestic and international. (shrink)

Emmanuel Levinas’s work seemingly places a great emphasis on language leading some commentators towards a Kantian reading of him where moral consideration would be based on the moral patient’s capacity for reason with language functioning as a proxy for this. Although this reading is possible, a closer look at Levinas’s descriptions of language reveal that its defining characteristic is not reason but the capacity to express beyond any thematized contents we would give to the Other. This expressivity (which Levinas calls (...) face) would confront me with their singularity, infinity, and interiority tying me to them in a relation of responsibility. And the “content” of such an expression is a vulnerability and exposure tied to their mortality which continually entreats me though I cannot take it away. It is by means of this bare expression of an exposure to death as the core of language that it will become possible for non-human mortal beings to have what Levinas calls language. This possibility, although not explicitly addressed by Levinas, is at least left open by his account of Bobby the dog as well as his agnosticism over a snake’s face. (shrink)

In recent years, questions regarding the ontological status of the human have been raised with renewed interest and imagination within various fields of critical thought. In the face of biotechnological findings and increasingly advanced technologies that connect as well as disturb settled boundaries, whether geographical or bodily, not to mention philosophical questionings of traditional western humanism, the boundaries of the human subject have been contested. The human body, traditionally imagined as closed and autonomous, has been opened up (...) to a world of forces and agencies that are strange, other and often deeply disturbing when viewed from an anthropocentric standpoint. Rather than close down anxieties concerning such boundary transgressions and ontological uncertainties, scholars – not least within areas such as feminist, posthumanist and queer theory – have argued that here lie possibilities as well as an ethical urgency to rethink the human subject, its world(s) and its others. Indeed, what might it mean to view the world from positions that do not take the pure and autonomous human form as its starting point? And what ethical considerations does such a viewpoint demand of us? (shrink)

Generic statements express generalizations about categories. Current theories suggest that people should be especially inclined to accept generics that involve threatening information. However, previous tests of this claim have focused on generics about non-human categories, which raises the question of whether this effect applies as readily to human categories. In Experiment 1, adults were more likely to accept generics involving a threatening property for artifacts, but this negativity bias did not also apply to human categories. Experiment 2 (...) examined an alternative hypothesis for this result, and Experiments 3 and 4 served as conceptual replications of the first experiment. Experiment 5 found that even preschoolers apply generics differently for humans and artifacts. Finally, Experiment 6 showed that these effects reflect differences between human and non-human categories more generally, as adults showed a negativity bias for categories of non-human animals, but not for categories of humans. These findings suggest the presence of important, early-emerging domain differences in people's judgments about generics. (shrink)

A Kantian approach can establish that non-human natural entities are morally considerable and that humans have duties to them. This is surprising, because most environmental ethicists have either rejected or overlooked Kant when it comes to this issue. Inspired by an argument of Christine Korsgaard, I claim that both humans and non-humans have a natural good, which is whatever allows an entity to function well according to the kind of entity it is. I argue that humans are required to (...) confer normative value on the natural good of all entities that have a natural good. This is so because, as a matter of fact, humans confer normative value on their own natural good simply because it is a natural good, which commits humans to the position that any natural good deserves to have normative value conferred on it. Since non-human natural entities have a natural good, their natural good deserves to have normative value conferred on it as well, and this is sufficient to make non-human natural entities morally considerable such that humans have duties to them.

An aesthetic and epistemological departure from ocular centrism has occurred in the wake of current technological evolutions and the posthuman turn. The sonic exploration of the more-than-human takes artists and philosophers beyond anthropomorphism to reveal the hidden patterning of life forms and yet-unfathomed universes. The conflation of nature with culture is one shift that takes place when thinking with sounds and rhythm and studying our environments. On an ontological level, a reordering of subject and object occurs when encountering the (...) reciprocal relationship of sounding. What if culture is actually nature? How does technology connect with botany, and what does it mean to engage the environment with the expanded tactility of the ear? This essay observes current inter-species practices in sound art by revisiting philosopher Susanne Langer’s theory of an embodied and embedded mind. Her “new key” in philosophy emphasizes music as a dynamic sound-pattern to conceptualize a semiology of artistic forms that renders human feeling in regard to non-human antecedents. This serves as a tool to trace the preconceptual substrata of mind, leading us through process-oriented studies of nature and psychophysical affect. Thinking with Langer involves the interconnection of natural systems, behavioural patterns, and human expression, which emerges in art. (shrink)

A complete theory of the permissibility of sex must not only determine the permissibility of sex between typical adult humans. In addition, it must also adequately take into consideration sex acts involving non-human animals, children, and humans with intellectual disabilities. However, when trying to develop a non-discriminatory account that includes these beings, two worrying problems of animal sex arise. To surpass them, I argue for a reformulation of the standard theory. To produce a truly inclusive account our theory should (...) be focused on assent, dissent, the significance of sex, and the similarity of the beings engaging in the sex act. (shrink)

Almost everyone who has a limb amputated will experience a phantom limb--the vivid impression that the limb is not only still present, but in some cases, painful. There is now a wealth of empirical evidence demonstrating changes in cortical topography in primates following deafferentation or amputation, and this review will attempt to relate these in a systematic way to the clinical phenomenology of phantom limbs. With the advent of non-invasive imaging techniques such as MEG (magnetoencephalogram) and functional MRI, topographical (...) reorganization can also be demonstrated in humans, so that it is now possible to track perceptual changes and changes in cortical topography in individual patients. We suggest, therefore, that these patients provide a valuable opportunity not only for exploring neural plasticity in the adult human brain but also for understanding the relationship between the activity of sensory neurons and conscious experience. We conclude with a theory of phantom limbs, some striking demonstrations of phantoms induced in normal subjects, and some remarks about the relevance of these phenomena to the question of how the brain constructs a 'body image.'.

This article focuses on situations and emotional perception. To this end, I start with the Kuleshov effect wherein identical shots of performers manifest different expressions when cut to different contexts. However, I conducted experiments with a twist, using Darth Vader and non-primates, and even here expressions varied with contexts. Building on historically and conceptually linked Gibsonian, Gestalt, phenomenological and pragmatic schools, along with consonant experimental work, I extrapolate these results to defend three interconnected points. First, I argue that while (...) perceiving expression is sometimes about reading minds, it is more squarely about perceiving solicitations or closures for action. Second, I frame expressions as a subcategory of Gibson’s affordances. This includes those showing up through context, in turn suggesting Kuleshov-like scenarios are not mere perceptual tricks. Third, I maintain that situations—with or without other human beings—have action-motivating expressive qualities or what Gestalt theorists called physiognomic characters, following Werner. These likewise emerge through ecological relations, and are very much like affordances and in the world as much as them. With resemblance theories, my account agrees that we perceive expression in the world. However, it indicates a broad range of cases in which expression shows up as consequences of overall situations that solicit or close actions, as opposed to mere resemblance between entities and human expressions.

The position of some environmental ethicists that some non-humans have intrinsic value as a mind-independent property is seriously flawed. This is because human beings lack any evidence for this position and hence are unjustified in holding it. For any possible world that is alleged to have this kind of intrinsic value, it is possible to conceive an observationally identical world that lacks intrinsic value. Hence, one is not justified in inferring the intrinsic value of some non-human from any (...) set of observable properties, since that same set of properties could just as well exist in a world that lacks intrinsic value. However, since human beings do not have a faculty of intuition that would allow them to .. (shrink)

According to indirect duty views, human beings lack direct moral duties to non-human organisms, but our direct duties to ourselves and other humans give rise to indirect duties regarding non-humans. On the orthodox interpretation of Kant’s account of indirect duties, one should abstain from treating organisms in ways that render one more likely to violate direct duties to humans. This indirect duty view is subject to several damaging objections, such as that it misidentifies the moral reasons we have (...) to treat non-humans in certain ways and that it sanctions only weak obligations vis-à-vis organisms. I develop an alternative indirect duty view: given a direct duty to oneself to cultivate virtuous dispositions, one has an indirect duty to abstain from treating organisms in ways that erode one’s virtues or develop vices. I argue that this indirect duty view strictly proscribes knowingly causing unnecessary harm to organisms, and I show that it is not subject to the damaging objections directed against the indirect duty view attributed to Kant by the orthodox interpretation. This suggests that indirect duty views are more worthy of consideration than is often supposed. (shrink)

Should models of consciousness be detailed _mechanistic_ models of particular types of systems, or should they be _minimal_ models that abstract away from the underlying mechanistic details and provide generalisations? Detailed mechanistic models may afford a complete and precise account of consciousness in human beings and other, physiologically similar mammals. But they do not provide a good model of consciousness in other animals, such as non-vertebrates, let alone artificial systems. Minimal models can be applicable to a wide range of (...) different conscious systems. But do they provide genuine explanations that are autonomous from explanations by detailed mechanistic models? This paper provides a taxonomy of minimal models and measures of consciousness, clarifies their relation to detailed mechanistic models, and highlights benefits of different minimalist approaches to consciousness.
