The creation of chimeras by introducing human stem cells into nonhu- man animals has provoked intense concerns. Addressing objections that appeal to human dignity, I focus in this essay on stem cell research intended to generate human neurons in Great Apes and rodents. After considering samples of dignity- based objections from the literature, I examine the underlying assumption that nonhuman animals have lower moral status than personsFwith particular attention to what it means to speak of higher and lower moral statusFbefore (...) evaluating the chimera research in question. I argue that (1) such experiments involving Great Apes should be prohibited out of respect for the research subjects and (2) such experiments involving rodents may or may not be permissible, depending on how we answer unresolved questions regarding rodents’ moral status. In the end, concerns about human dignity prove insignificant. (shrink)

Research on mirror self-recognition where animals are observed for mirror-guided self-directed behaviour has predominated the empirical approach to self-awareness in nonhuman primates. The ability to direct behaviour to previously unseen parts of the body such as the inside of the mouth, or grooming the eye by aid of mirrors has been interpreted as recognition of self and evidence of a self-concept. Three decades of research has revealed that contrary to monkeys, most great apes have convincingly displayed the capacity to recognize (...) self by mirrors. The putative discontinuity in phylogeny of the ability suggests the existence of a so-called cognitive gap between great apes and the rest of the animal kingdom. However, methodological and theoretical inconsistencies regarding the empirical approach prevail. For instance, the observation of self-directed behaviour might not be as straightforward as it seems. In addition, the interpretation of mirror self-recognition as an index of self-awareness is challenged by alternative explanations, raising doubt about some assumptions behind mirror self-recognition. To evaluate the significance of the test in discussions of the concept of self this paper presents and analyses some major arguments raised on the mirror task. (shrink)

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

There is an unacknowledged disagreement on what kind of dialogue best supports democracy. Many view democracy as analogous to a law court and so view “democratic dialogue” as a contest between competing advocates who have acquired the kind of “steel trap” critical thinking skills that are ideal for winning in the external marketplace of ideas. Others assume that the propensity to seriously reflect on opposing viewpoints within the minds of individuals is ideal for democratic maintenance. It will be argued here (...) that our love affair with “critical thinking” that tends to support an external battle of ideas harms democracy. It will be argued that the complexity of our common humanity, the complexity of our form of governance, the complexity of the approaches needed to face wicked problems, and the complexity of the internal engine of personal development requires that we learn to readily engage in open truth-seeking dialogue with those who hold opposing viewpoints and in so doing, enhance the dimensionality through which we view the world. With regard to the educational implications, this suggests that, since engaging in dialogue across difference is the essence of the pedagogical framework that anchors Philosophy for Children, Philosophy for Children ought to be embraced as an essential component of any educational enterprise that views cultivating democratic citizenship as part of its mandate.

Though central to metaphysics, and exciting for entertainment, the fact that selves are invisible, has received insufficient attention in the field of P4C, and virtually none in the field of education in general. This may not be surprising as the enthusiasm to enrich “minds” both with essential information as well as with critical, creative, and cooperative inquiry skills, may blind educators to the fact that their initiatives (even those that are dialogical) may not touch how children view themselves, nor how (...) they ought to function in the world as they find it. It will be argued here that, if ethical development, or democratic citizenship, or authenticity, or any other “self-education” initiative is on the educative menu, strategies (detailed here) must be undertaken to ensure that all parties are truly present, in body, mind and self. It will be further argued that since educating selves can be done at the same time as educating minds (e.g., nurturing reasoning skills), and since a Community of Philosophical Inquiry (unlike other educational strategies), in its dialogical structure, has the unique potential to solicit and hence educate selves, and since such “self-education” is an education for “making a life,” rather than the more common educative concern of educating for “making a living,” facilitators who do not activate the unique power of a CPI to enhance personhood are remiss in their responsibility to their charges.

This thesis is about experiential content: what it is; what kind of account can be given of it. I am concerned with identifying and attacking one main view - I call it the inferentialist proposal. This account is central to the philosophy of mind, epistemology and philosophy of science and perception. I claim, however, that it needs to be recast into something far more subtle and enriched, and I attempt to provide a better alternative in these pages. The inferentialist proposal (...) holds that experiential content is necessarily under¬pinned by sophisticated cognitive influences. My alternative, the continuum theory, holds that these influences are relevant to experience only at certain levels of organisation and that at other levels there are contents which such features do not capture at all. Central to my account is that there are degrees to which cognitive influences affect experiential content; indeed, for the most part, experience is an amalgam of both inferential and non-inferential features. I claim that the inferentialist proposal is fundamentally flawed and deserves replacement, and I argue that my alternative fills the hollow that remains. The thesis is divided into four sections. In Part I, Chapter 1, I introduce two traditionally rival views of experiential content. In Chapter 2, I develop my continuum alternative. Chapter 3 assesses the relationship between experience and language, while Chapter 4 explores the relationship between beliefs and experience. The overall argument is that it has been a mistake to understand experience simply in inferential or non-inferential terms. In Part II, I examine the structure of mental content. Chapter 5 is concerned with the kinds of experiences which escape the inferentialist analysis. Chapter 6 considers Kant’s metaphysic of experience counterpointed to Lorenz’s reading of his work in the light of evolutionary biology. Chapter 7 treats animal experience in relation to the continuum view I am developing, while Chapter 8 reviews Fodor’s contribution to perceptual psychology. It is argued that the view of experiential content being developed is both consistent with empirical data on informationally local perceptual sub-systems, but also accords well with evolutionary theory and a naturalist interpretation of Kant’s taxonomy. Part III deals with inferentialism in the philosophy of science. In Chapter 9, I assess the theory dependence of observation thesis as it is advanced by Paul Feyerabend. I bring out of his account a subtle confusion concerning the importance of inference in the context of scientific inquiry. Part IV deals with the issue of experience in the philosophy of mind. In Chapter 10, I look at Wilfred Sellars’s attack on sense data theories. Chapter 11 confronts Paul Churchland’s treatment of ‘folk psychology’ while Chapter 12 isolates the issue of experiential qualia and the position of property dualism. I offer a critical review of Thomas Nagel’s work in this chapter and claim that his position can be read in a way which is consistent with the continuum account I am developing. I conclude the thesis in the usual fashion with a summary of the central claims. (shrink)

One of the central questions within contemporary debates about collective intentionality concerns the notion and status of the we. The question, however, is by no means new. At the beginning of the last century, it was already intensively discussed in phenomenology. Whereas Heidegger argued that a focus on empathy is detrimental to a proper understanding of the we, and that the latter is more fundamental than any dyadic interaction, other phenomenologists, such as Stein, Walther and Husserl, insisted on the importance (...) of empathy for proper we-experiences. In this paper, I will present some of the key moves in this debate and then discuss and assess Husserl’s specific proposal, according to which reciprocal empathy, second-person engagement and self-alienation are all important presuppositions for group-identification and we-identity.

Mirror self-experience is re-casted away from the cognitivist interpretation that has dominated discussions on the issue since the establishment of the mirror mark test. Ideas formulated by Merleau-Ponty on mirror self-experience point to the profoundly unsettling encounter with one’s specular double. These ideas, together with developmental evidence are re-visited to provide a new, psychologically and phenomenologically more valid account of mirror self-experience: an experience associated with deep wariness.

Alongside in vitro studies, researchers are increasingly exploring the transplantation of human brain organoids (HBOs) into non-human animals to study brain development, disease, and repair. This paper focuses on ethical issues raised by such transplantation studies. In particular, it investigates the possibility that they might yield enhanced brain function in recipient animals (especially non-human primates), thereby fundamentally altering their moral status. I assess the critique, raised by major voices in the bioethics and science communities, according to which such concerns are (...) premature and misleading. I identify the assumptions underlying this skeptical critique, and mention some objections against them, followed by some possible replies. I proceed to argue that the skeptical position is ultimately implausible, because it presupposes an unreasonably high standard of full moral status. My argument appeals to David DeGrazia’s idea of a “borderline person”, and to the need for consistency with existing animal research regulations. I outline the practical implications of my view for the conduct of studies that might result in the development of full moral status in a transplanted animal. I also discuss some of the ethical implications of animal enhancement (particularly of rodents) below the threshold associated with full moral status. I conclude that far from being premature, further debate on these issues is urgently needed to help clarify the prospects that a neural chimera might attain full moral status in the foreseeable future, and the level of quality of life required to make it acceptable to knowingly create such a being via HBO transplantation.

The conclusions drawn from mirror self-recognition studies, in which nonhuman animals are tested for whether they detect a mark on their bodies which can be observed only in the mirror, are based on several presuppositions. These include that performance on the test is an indication of species wide rather than individual abilities, and that all the animals which pass the test are demonstrating the presence of the same psychological ability. However, further details about the results of the test indicate that (...) these presuppositions are false. Animals take the test as individuals, not as stand-ins for species, and members of different species rely on different cognitive mechanisms to pass the test. For nonhuman animals, passing the test seems to be a consequence of enculturation and practice. (shrink)

Are nonhuman non-linguistic animals self-conscious? And how is it possible to find out whether they are or not? This question raises two interrelated problems: the conceptual problem and the methodological problem. In order to approach an answer, it is first and foremost necessary to establish criteria for self-consciousness by considering the phenomenon and the abilities connected with it. Subsequently, one can survey the experimental paradigms. Do the experiments really show that the identified ability has to be used to successfully master (...) the given task? Is the presence of self-consciousness the best explanation for the empirical data? This paper proposes that the underlying ability for self-consciousness is the capacity to have mental states, where the subject is thought of as the subject of the mental state. Furthermore, two important current experimental paradigms will be evaluated for their usefulness to identify the presence of self-consciousness. The verdict will be negative. Neither ‘mirror self-recognition’ nor ‘uncertainty monitoring’ need to employ the aforementioned ability in order to be executed. (shrink)

To the three classic wounds to human narcissism – that of Copernicus , Darwin , and Freud – there must be appended a fourth wound: man is not the only subject in the universe. While most philoso- phers are unwilling to accept it, ethological research shows that animals are also subjects; indeed, in human/animal hybrid communities, certain animals can become individuals or even persons. Through animal biography, anec- dotes, and other often disqualified but nonethe- less empirical forms of knowledge, we (...) can come to know these singular animals. (shrink)

The preceding article by Marc Bekoff reveals much about our current understanding of animal self-consciousness and its implications. It also reveals how much more there is to be said and considered. This response briefly examines animal self-consciousness from scientific, moral, and theological perspectives. As Bekoff emphasizes, self-consciousness is not one thing but many. Consequently, our moral relationship to animals is not simply one based on a graded hierarchy of abilities. Furthermore, the complexity of animal self-awareness can serve as stimulus for (...) thinking about issues of theodicy and soteriology in a broader sense. (shrink)

With all the attention given to the study of consciousness recently, the topic of self-consciousness has been relatively neglected. “It is of course [phenomenal] consciousness rather than...self-conscious that has seemed such a scientific mystery,” a prominent philosopher comments.1 Phenomenal consciousness concerns the aspect of a state that feels a certain way: roses smell like this; garlic tastes like that; middle C sounds like this, and so on. Although phenomenal consciousness is surely a fruitful area of scientific investigation, I hope to (...) demonstrate here that investigation of selfconsciousness offers its own rewards, ontologically speaking.

That great apes are the only primates to recognise their reflections is often taken to show that they are self-aware—however, there has been much recent debate about whether the self-awareness in question is psychological or bodily self-awareness. This paper argues that whilst self-recognition does not require psychological self-awareness, to claim that it requires only bodily self-awareness would leave something out. That is that self-recognition requires ‘objective self-awareness’—the capacity for first person thoughts like ‘that's me’, which involve self-identification and so are (...) vulnerable to error through misidentification. This objective self-awareness is distinct from bodily or psychological self-awareness, requires cognitive sophistication and provides the beginnings of a more conceptual self-representation which might play a role in planning, mental time travel and theory of mind.

In keeping with recent views of consciousness of self as represented in the body in action, empirical studies are reviewed that demonstrate a bottlenose dolphin’s conscious awareness of its own body and body parts, implying a representational “body image” system. Additional work reviewed demonstrates an advanced capability of dolphins for motor imitation of self-produced behaviors and of behaviors of others, including imitation of human actions, supporting hypotheses that dolphins have a sense of agency and ownership of their actions and may (...) implicitly attribute those levels of self-awareness to others. Possibly, a mirror-neuron system, or its functional equivalent to that described in monkeys and humans, may mediate both self-awareness and awareness of others. (shrink)

This article offers a general definition of self-knowledge that embraces all forms and levels of self-knowledge in animals and humans. It is hypothesized that various levels of self-knowledge constitute an ordinal scale such that each species in a lineage displays the forms of self-knowledge found in related species as well as new forms it and its sister species may have evolved. Likewise, it is hypothesized that these various forms of levels of self-knowledge develop in the sequence in which they evolved. (...) Finally, a general hypothesis for the functional significance of self-knowledge is proposed along with subhypotheses regarding the adaptive significance of various levels of self-knowledge in mammals including human and nonhuman primates. The general hypothesis is that self-knowledge serves as a standard for assessing the qualities of conspecifics compared to those of the self. Such assessment is crucial to deciding among alternative reproductive and subsistence strategies. The qualities that are assessed, which vary across taxa, range from the size and strength of the self to its mathematical or musical abilities. This so-called assessment model of self-knowledge is based on evolutionary biological models for social selection and the role of assessment in animal communication. (shrink)

Priority of the “self” is thought to be evolutionarily advantageous. However, evidence for this priority has been sparse. In this study, subjects performed a gender categorization task on self- and non-self target faces preceded by either congruent or incongruent periliminal or subliminal primes. We found that subliminal primes induced a priming effect only on self target faces. This discovery of a self-specific priming effect suggests that functional specificity for faces may include timing as well as spatial adaptations.

This paper is an account of the co-construction of categorical identity and personal identity among human beings. As people recognize themselves within a socially sanctioned categorical scheme, they reproduce that scheme, and hence institutional and personal reflexivity occur as a joint movement that, at the same time, can be seen as an exercise in social control. The inspirations for this account are lan Hacking's view about the distinctiveness of social kinds from natural kinds, and Dan Sperber's idea about cultural communication (...) as a form of social epidemiology.

The ‘self’ is increasingly used as a variable in cognitive experiments and correlated with activity in particular areas in the brain. At first glance, this seems to transform the self from an ephemeral theoretical entity to something concrete and measurable. However, the transformation is by no means unproblematic. We trace the development of two important experimental paradigms in the study of the self, self-face recognition and the adjective self ascription task. We show how the experimental instrumentalization has gone hand in (...) hand with a simplification of the self-concept, and how more conceptual and theoretical reflections on the structure, function and nature of self have either disappeared altogether or receded into the background. We argue that this development impedes and complicates the interdisciplinary study of self. (shrink)

In the rubber hand illusion one’s hand is hidden, and a fake hand is visible. We explored the situation in which visual information was available indirectly in a mirror. In the mirror condition, compared to the standard condition , we found no reduction of the RHI following synchronised stimulation, as measured by crossmanual pointing and by a questionnaire. We replicated the finding with a smaller mirror that prevented visibility of the face. The RHI was eliminated when a wooden block replaced (...) the fake hand, or when the hand belonged to another person or mannequin. We conclude that awareness of the reflection is the critical variable, despite the distant visual localisation of the hand in a mirror and the third-person perspective. Stimuli seen in a mirror activate the same response as stimuli seen in peripersonal space, through knowledge that they are near one’s body. (shrink)

Many animal species use tools, but human technical engagement is more complex. We argue that there is coevolution between technical engagement and advanced forms of causal cognition in the human lineage. As an analytic tool, we present a classification of different forms of causal thinking. Human causal thinking has become detached from space and time, so that instead of just reacting to perceptual input, our minds can simulate actions and forces and their causal consequences. Our main thesis is that, unlike (...) the situation for other primate species, an increasing emphasis on technical engagement made some hominins capable of reasoning about the forces involved in causal processes. This thesis is supported in three ways: We compare the casual thinking about forces of hominins with that of other primates. We analyze the causal thinking required for Stone Age hunting technologies such as throwing spears, bow hunting and the use of poisoned arrows, arguing that they may serve as examples of the expansion of casual cognition about forces. We present neurophysiological results that indicate the facilitation of advanced causal thinking. (shrink)

This volume is a collection of some of the most important philosophical papers by Peter Gärdenfors. Spanning a period of more than 20 years of his research, they cover a wide ground of topics, from early works on decision theory, belief revision and nonmonotonic logic to more recent work on conceptual spaces, inductive reasoning, semantics and the evolutions of thinking. Many of the papers have only been published in places that are difficult to access. The common theme of all the (...) papers is the dynamics of thought. Several of the papers have become minor classics and the volume bears witness of the wide scope of Gärdenfors’ research and of his crisp and often witty style of writing. The volume will be of interest to researchers in philosophy and other cognitive sciences. (shrink)

Over the past several years, the study of self-related cognition has garnered increasing interest amongst psychologists and cognitive neuroscientists. Concomitantly, lesion and neuroimaging studies have demonstrated the importance of intact cortico-cortical and cortico-subcortical connections for supporting high-level cognitive functions. Commissurotomy or “split-brain” patients provide unique insights into the role of the cerebral commissures in maintaining an individual’s sense of self, as well as into the unique self-representation capabilities of each cerebral hemisphere. Here we review empirical work examining the integrity of (...) self-related processes in patients with various disconnection syndromes, focusing on studies of self-recognition, ownership, and agency. Taken together, this body of work suggests that an intact corpus callosum enabling interhemispheric transfer is necessary for some, but not all types of self-representations. (shrink)
