Development of Consciousness

There is a close relationship between the developments of personal identity and consciousness throughout life. Underlying both is a fundamental question for each of us: Who am I? However, this relationship has mainly been studied in certain socio-cultural contexts. Moreover, previous studies that have integrated pre-personality and trans-personality as natural extensions of personal identity do not offer a critical, philosophical and humanistic analysis informed by the latest advances in neuroscience. I distinguish five basic identities: biological, social, autotelic, universal, and presential. (...) Narrative identity is characterized as the major impediment to the discovery of the other identities. The possible existence of an authentic identity beyond any identification is discussed. Parallels between motivation for action and the developments of identity and consciousness are also highlighted. It is proposed to combine the multidimensional and hierarchical perspectives in order to obtain a more realistic, integrative and logically structured view of the different individual pathways. Finally, I establish connections with lines of humanism, philosophy, psychology, and theology not usually linked to the study of identity, to offer a global and integrative vision. (shrink)

The ability to anticipate events, to foresight, is an adaptive advantage. We humans use it all the time. Animals have a limited access to it. Positioning foresight in human evolution is a complex subject (Suddendorf, 2013). Why and how are humans, and not chimpanzees, performant in anticipating events? We propose here to address that question with an evolutionary scenario that links self-consciousness to anxiety management (Menant, 2018). The scenario positions self-consciousness as “the capability to represent one’s own entity as existing (...) in the environment, like conspecifics are represented as existing” (making “thinking about oneself” possible). The scenario proposes that our pre-human ancestors were capable of some level of identifications with their conspecifics, and that its development has progressively brought our ancestors to represent themselves as existing in the environment like their conspecifics were represented, thus introducing self-consciousness. The scenario also proposes that identifications with suffering conspecifics have been the source of an important anxiety that had to be limited for evolution to continue. Some of our ancestors have not been able to limit that new anxiety. Their mental pain became unbearable. Their evolution was almost stopped, thus initiating the pan-homo split. Developing an ability to anticipate events has been a key contributor to anxiety limitation by providing information about the sufferings to come, and consequently allowing to limit and avoid them. In addition to that role of foresight in human evolution it is worth noticing that the associated chaining of mental events brings to propose foresight as an entry point to the concept of causality in human evolution. Regarding our chimpanzee cousins, the pan-homo split in the scenario positions them as not self-conscious, not capable of anticipation like humans are, and less anxious than humans. Continuations are proposed. (shrink)

It is agreed by most people that self-consciousness is the result of an evolutionary process, and that representations may have played an important role in that process. We would like to propose here that some evolutionary stages can highlight links existing between representations and the notion of self, opening a possible path to the nature of self-consciousness. Our starting point is to focus on representations as usage oriented items for the subject that carries them. These representations are about elements of (...) the environment including conspecifics, and can also represent parts of the subject without refering to a notion of self (we introduce the notion of "auto-representation" that does not carry the notion of self-representation). Next step uses the performance of intersubjectivity (mirror neurons level in evolution) where a subject has the capability to mentally simulate the observed action of a conspecific (Gallese 2001). We propose that this intersubjectivity allows the subject to identify his auto-representation with the representations of his conspecifics, and so to consider his auto-representation as existing in the environment. We show how this evolutionary stage can introduce a notion of self-representation for a subject, opening a road to self-conciousness and to self. This evolutionary approach to the self via self- representation is close to the current theory of the self linked to representations and simulations (Metzinger 2003). We use a scenario about how evolution has brought the performance of self-representation to self-consciousness. We develop a process describing how the anxiety increase resulting from identification with endangered or suffering conspecifics may have called for the development of tools to limit this anxiety (empathy, imitation, language), and how these tools have accelerated the evolutionary process through a positive feedback on intersubjectivity (Menant 2004, 2005). We finish by summarizing the points addressed, and propose some possible continuations. (shrink)

Primatology tells that about seven million years ago a split began in primate evolution, a split that led to chimpanzee and human lineages (the pan-homo split). During these millions of years our human lineage has developed performances that our chimpanzee cousins do not possess, like reflective self-consciousness and language. We present here an evolutionary scenario that proposes a rationale for the pan-homo split. It is based on a pre-human anxiety that may have barred access to self-consciousness for the chimpanzee lineage. (...) The starting point of the scenario is the capability that had our pre-human ancestors for an elementary identification with conspecifics. We consider that the evolution of that capability has led to self-consciousness when identifications with conspecifics brought our ancestors to represent their own entities as existing as conspecifics were represented. But the same identification process also took place with suffering or endangered conspecifics. And this has produced a huge anxiety increase, source of important mental sufferings that our ancestors had to limit (ESPP 2021). Our hypothesis is that different modes of anxiety limitation have led to the pan-homo split. On one side the chimpanzee lineage would have limited an unbearable mental suffering by stopping the development of identification with conspecifics, and by this also stopping a possible evolution toward self-consciousness. Such anxiety limitation process would have led to today chimpanzees which possess a very limited consciousness of themselves. On the other side our human lineage would have successfully developed anxiety limitation tools like caring, pleasure, anticipation, communication and imitation. And these tools have accelerated the evolution of our lineage toward our human mind. The proposed pan/homo process complements an existing evolutionary scenario for self-consciousness that has positioned anxiety management as a key contributor to the build-up of our human minds (ASSC 25). Such overall perspective makes anxiety management a major source to many of our motivations and mental states, much more than assumed so far. Continuations are proposed for a better understanding about our modes of anxiety limitation (including evil behaviors), and also to introduce a possible evolutionary nature of phenomenal consciousness. -/- .

It is pretty obvious that language and human consciousness entertain tight relations. We could not really be conscious of ourselves without the possibility to say “I” or “me”. And language is a key contributor in our capability to identify ourselves as conscious entities existing in the environment. But the relations linking language and consciousness are complex and difficult to analyze. Evolutionary origins of language are unknown as no fossil traces have been left by our ancestors. Sciences of consciousness however begin (...) to make available some possible evolutionary scenarios about the nature of human consciousness. We want here to propose a link between language and consciousness by using such an evolutionary scenario and also introduce the usage of a systemic approach to meaning generation. In the first part of the presentation we will use an existing scenario about the evolutionary nature of self-consciousness where the development of language has a role (1). We will highlight this role in order to identify language and self-consciousness as inter-dependant in their nature through a possible common evolutionary origin. Self-consciousness and language could then be considered as tightly inter-dependant through a common build up of human nature during evolution. The scenario presents an evolutionary nature of self-consciousness as resulting of the capability for pre-human primates to identify with their conspecifics (1, 2). The conspecifics are represented as existing in the environment, and such identification brought our pre-human ancestors to consider themselves as also existing in the environment. The scenario takes this event as being a first step for a conscious self-representation within pre-human primates, which progressively evolved toward our today human consciousness (3). But such identification with conspecifics was not for free at times of survival of the fittest. Identifying with conspecifics meant for our pre-human ancestor to also identify with their sufferings or encountered dangers. These came in addition to the dangers or sufferings naturally encountered and created a significant anxiety increase (1). The resulting level of anxiety had to be limited. One possibility for that was to develop psychological or physical tools that could have reduced the risks of occurrences and developments of such dangers and sufferings. Among these tools is the performance of language which can induce significant evolutionary advantages. We will propose a first scheme about how these evolutionary advantages could have reduced the dangers and sufferings encountered by our pre-human ancestors. We will also show how the development of language produced by itself a positive feedback on the development of inter-subjectivity in the evolutionary scenario, and so participated directly to the development of human consciousness. Other evolutionary advantages have existed like the development of imitation and synergy through experience (4). Language played a role there also, and has to be taken into account. The second part of the presentation will propose the usage of an existing systemic approach to meaning generation in terms of constraints satisfaction (5, 6). Constraints for pre-human primates, ranging from a basic “stay alive” to highly elaborated “limit anxiety”, were source of multiple meaning generations in which language has played (and still plays) a key role. Several continuations will be proposed linked to the here above thread on a co-evolutions of language and human consciousness, as based on the evolutionary scenario. (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)

This presentation is about an evolutionary scenario for self-consciousness linked to a human specific anxiety. It is a continuation of other works (2011 Book chapter, 2014 TSC Poster). AIM: Present a scenario describing an evolutionary nature of self-consciousness that introduces a human specific anxiety which is active in our human lives. METHOD: The scenario starts with our pre-human ancestors which were capable to manage representations and to partly identify with their conspecifics (Olds 2006, DeWaal 2008). These identifications brought our ancestors (...) to merge the representations of their conspecifics with the limited auto-representation of their own entity. The result was an auto-representation becoming about an entity existing in environment. This process is proposed as having progressively generated an ancestral form of self-consciousness as object and as subject. These identifications took place also with suffering conspecifics and have imposed to our ancestors a huge anxiety increase that had to be limited. Tools developed for that limitation (caring, collaboration, empathy, ToM, ...) have linked consciousness to anxiety management while also procuring evolutionary benefits. Human minds now contain an unconscious part of that ancestral anxiety that guides many of our mental states. RESULT: An evolutionary scenario for self-consciousness is made available as linked to a specific anxiety management that characterizes human minds. Continuations are introduced, some related to mental health. CONCLUSION: The proposed evolutionary scenario presents self-consciousness and a specific human anxiety as sharing a same evolutionary nature. This new source of anxiety needs more investigations.

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)

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)

Two questions about infant consciousness are especially central. First: are infants conscious? Second: what is infants’ conscious experience like? In previous work, I have addressed the first, arguing that newborn babies are conscious at birth and that it is possible to know something about what infants’ experiences are like. In this talk, I address the second, investigating the phenomenal structure of infant consciousness. I discuss whether infants have a rich or a minimal phenomenology. The current consensus is that infants have (...) perceptual experiences and experiences of pain and pleasure. But, do they have other types of phenomenology? Using Kriegel’s framework from The Varieties of Consciousness (2015), I explore whether infants have sensory phenomenology, cognitive phenomenology, imaginative phenomenology, emotional phenomenology, and agentive phenomenology. I also address the question of what is the phenomenal background of infants’ first-person experiences, and whether or not they have a minimal pre-reflexive structure of consciousness. (shrink)

The material world is determined and its boundaries are established on the basis of fundamental physical laws. It turns out that the non-material world is not empty. In this world the substance has been discovered that looks like a consciousness. Consciousness has the ability to interact with matter and determine the state of matter within the limits determined by the Heisenberg uncertainty relations. It is shown that elementary particles have something that can be called as elementary consciousness. More complicated consciousnesses (...) determine the behavior of animals and humans, in particular. To explain the diversity of consciousnesses in terms of the level of development, the hypothesis of the fusion of consciousnesses is proposed. The hypothesis leads to an explanation of the possible existence of that is commonly called God. Within the framework of the hypothesis, explanations of testimonies of clinical death survivors are given. Possible goals of the existence of man and God are determined. (shrink)

We suggest that there is confusion between why consciousness developed and what additional functions, through continued evolution, it has co-opted. Consider episodic memory. If we believe that episodic memory evolved solely to accurately represent past events, it seems like a terrible system—prone to forgetting and false memories. However, if we believe that episodic memory developed to flexibly and creatively combine and rearrange memories of prior events in order to plan for the future, then it is quite a good system. We (...) argue that consciousness originally developed as part of the episodic memory system—quite likely the part needed to accomplish that flexible recombining of information. We posit further that consciousness was subsequently co-opted to produce other functions that are not directly relevant to memory per se, such as problem-solving, abstract thinking, and language. We suggest that this theory is compatible with many phenomena, such as the slow speed and the after-the-fact order of consciousness, that cannot be explained well by other theories. We believe that our theory may have profound implications for understanding intentional action and consciousness in general. Moreover, we suggest that episodic memory and its associated memory systems of sensory, working, and semantic memory as a whole ought to be considered together as the conscious memory system in that they, together, give rise to the phenomenon of consciousness. Lastly, we suggest that the cerebral cortex is the part of the brain that makes consciousness possible, and that every cortical region contributes to this conscious memory system. (shrink)

In this paper, I will argue that newborns are conscious at birth and that it is possible to know what infants’ experiences are like. I propose a methodology for investigating infant consciousness, and I present two approaches for determining whether infants are conscious. First, I will consider behavioral and neurobiological markers of consciousness. Second, I investigate the major theories of consciousness, including both philosophical and scientific theories, and I discuss what they predict about infant consciousness.

This article extends the brief description of cognition previously offered in the adaptational theory of consciousness (ATC). Here I suggest how unconscious and conscious minds interact to achieve mutual cognitive development. Interactions occur in an extended moment of subjective time consisting of perceptual, associational, and affective scenes. During the extended moment, the conscious self becomes time-agile, shuttling between the past, present, and future in order to assemble ideas within global awareness that produce pleasure. The products of its cognitive journeys are (...) saved as synaptic modifications by the unconscious mind's mnemonic functions. As this occurs, instincts and the conscious self's implementation of cultural values are brought into better alignment. (shrink)

A strategy for investigating consciousness that has proven very productive has focused on comparing brain processes that are accompanied by consciousness with processes that are not. But comparatively little attention has been given to a related strategy that promises to be even more fertile. This strategy exploits the fact that as individuals develop, new classes of brain processes can transition from operating ‘in the dark’ to becoming conscious. It has been suggested that these transitions occur when a new class of (...) brain processes becomes object to a new, emergent, higher-level subject. Similar transitions are likely to have occurred during evolution. An evolutionary/developmental research strategy sets out to identify the nature of the transitions in brain processes that shift them from operating in the dark to ‘lighting up’. The paper begins the application of this strategy by extrapolating the sequence of transitions back towards its origin. The goal is to reconstruct a minimally-complex, subject-object subsystem that would be capable of giving rise to consciousness and providing adaptive benefits. By focusing on reconstructing a subsystem that is simple and understandable, this approach avoids the homunculus fallacy. The reconstruction suggests that the emergence of such a minimally-complex subsystem was driven by its capacity to coordinate body-environment interactions in real time e.g. hand-eye coordination. Conscious processing emerged initially because of its central role in organising real-time sensorimotor coordination. The paper goes on to identify and examine a number of subsequent major transitions in consciousness, including the emergence of capacities for conscious mental modelling. Each transition is driven by its potential to solve adaptive challenges that cannot be overcome at lower levels. The paper argues that mental modelling arose out of a pre-existing capacity to use simulations of motor actions to anticipate the consequences of the actions. As the capacity developed, elements of the simulations could be changed, and the consequences of these changes could be ‘thought through’ consciously. This enabled alternative motor responses to be evaluated. The paper goes on to predict significant new major transitions in consciousness. (shrink)

The scientific study of consciousness or subjective experiencing is a rapidly expanding research program engaging philosophers of mind, psychologists, cognitive scientists, neurobiologists, evolutionary biologists and biosemioticians. Here we outline an evolutionary approach that we have developed over the last two decades, focusing on the evolutionary transition from non-conscious to minimally conscious, subjectively experiencing organisms. We propose that the evolution of subjective experiencing was driven by the evolution of learning and we identify an open-ended, representational, generative and recursive form of associative (...) learning, which we call Unlimited Associative Learning (UAL), as an evolutionary transition marker of minimal consciousness. This evolutionary marker provides evidence that the evolutionary transition to consciousness has gone to completion and allows reverse-engineering from this learning capacity to the system that enables it – making possible the construction of a toy model of UAL. The model allows us to identify some of the key processes and structures that constitute minimal consciousness, points its taxonomic distribution and the ecological context in which it first emerged, highlights its function and suggests a framework for exploring developmental and evolutionary modifications of consciousness. We point to ways of experimentally testing the relationship between UAL and consciousness in human and in non-human animals and discuss the theoretical and ethical implications of our approach. The framework we offer allows the exploration of the evolutionary changes in agency, value systems, selective processes and goals that were involved in the transition to subjective experiencing from a perspective that resonates with the approaches of bio-semioticians.

The mainstream science of consciousness offers a few predominate views of how the brain gives rise to awareness. Chief among these are the Higher-Order Thought Theory, Global Neuronal Workspace Theory, Integrated Information Theory, and hybrids thereof. In parallel, rapid development in predictive processing approaches have begun to outline concrete mechanisms by which interoceptive inference shapes selfhood, affect, and exteroceptive perception. Here, we consider these new approaches in terms of what they might offer our empirical, phenomenological, and philosophical understanding of consciousness (...) and its neurobiological roots.

This commentary addresses the concept of learning stemming from Eva Jablonka and Simona Ginsburg’s theory of the emergence of consciousness. Jablonka and Ginsburg find strong support in biosemiotics for their argument that learning offers an evolutionary transition marker for the emergence of consciousness. Indeed, biosemiotics embraces a view on evolution that integrates both phylogeny and ontogeny. It does not polarize learning and evolving. At the same time, Jablonka and Ginsburg’s argument gives both biosemiotics and learning theory a shake, forcing scholarship (...) in these fields to tackle difficult questions on agency, selfhood, consciousness and anthropological difference. I explore some of the main questions that arise from this theoretical development, particularly in reference to Andrew Stables’ semiotic learning theory, which has been easily nested in a biosemiotic framework.

The evolutionary origin of consciousness has been a growing area of study in recent years. Nevertheless, there is intense debate on whether the existence of phenomenal consciousness without the cerebral cortex is possible. The corticocentrists have an empirical advantage because we are quasi-confident that we humans are conscious and have the well-developed cortex as the site of our consciousness. However, their prejudice can be an anthropic bias similar to the anthropocentric prejudice in pre-Darwinian natural history. In this paper, I propose (...) three basic principles to provide a conceptual basis for evolutionary studies of consciousness: the non-solipsistic principle, the evolution principle, and the anthropic principle. These principles collectively help us to avoid solipsism, anthropocentrism, and anthropomorphism to some degree, although we cannot be completely free from them. Also, the landscape metaphor associated with the anthropic principle provides an image of how different forms of consciousness can be acquired. (shrink)

In order to develop a true biological science of consciousness, we have to remove humans from the center of reference and develop a bottom-up comparative study of animal minds, as Donald Griffin intended with his call for a “cognitive ethology.” In this article, I make use of the pathological complexity thesis (Veit 2022a, b, c ) to show that we can firmly ground a comparative study of animal consciousness by drawing on the resources of state-based behavioral life history theory. By (...) comparing the different life histories of gastropods and arthropods, we will be able to make better sense of the possible origins of consciousness and its function for organisms in their natural environments.

This article develops a Hegelian account of self-consciousness by grounding it in being animal. It draws on contemporary naturalist and rationalist philosophy to support a transformative picture of the relationship between self-consciousness and animal purposes, setting work by Danielle Macbeth, Terry Pinkard, Michael Thompson, and Matthew Boyle into dialogue with two passages from Hegel’s Aesthetics. Because we are conscious of them as such, the article argues, our ends are never simply given to us and must be determined, which means working (...) them out collectively. But this makes dependency a structural feature of human life, as attaining the right relation to our ends means finding ourselves through the eyes of others instantiating our lifeform. Grounding these Hegelian insights in a naturalistic understanding of organic norms, we see that we should not oppose the self-transparency afforded by rationality to the opacity of animal drives. The article concludes that the mark of rationality is not the capacity to transcend or control animal instinct but that we can be problems to ourselves. Spiritual life is just natural life: natural life finding itself problematic. (shrink)

This is a response to the nine commentaries on our target article “Unlimited Associative Learning: A primer and some predictions”. Our responses are organized by theme rather than by author. We present a minimal functional architecture for Unlimited Associative Learning that aims to tie to together the list of capacities presented in the target article. We explain why we discount higher-order thought theories of consciousness. We respond to the criticism that we have overplayed the importance of learning and underplayed the (...) importance of spatial modelling. We decline the invitation to add a negative marker to our proposed positive marker so as to rule out consciousness in plants, but we nonetheless maintain that there is no positive evidence of consciousness in plants. We close by discussing how UAL relates to development and to its material substrate. (shrink)

In this essay, we discuss Simona Ginsburg and Eva Jablonka’s The Evolution of the Sensitive Soul from an interdisciplinary perspective. Constituting perhaps the longest treatise on the evolution of consciousness, Ginsburg and Jablonka unite their expertise in neuroscience and biology to develop a beautifully Darwinian account of the dawning of subjective experience. Though it would be impossible to cover all its content in a short book review, here we provide a critical evaluation of their two key ideas—the role of Unlimited (...) Associative Learning in the evolution of, and detection of, consciousness and a metaphysical claim about consciousness as a mode of being—in a manner that will hopefully overcome some of the initial resistance of potential readers to tackle a book of this length.

From one of the world's leading neuroscientists--a succinct, illuminating, wholly engaging investigation of the phenomenon of consciousness. In recent decades, many philosophers and cognitive scientists have declared the question of consciousness unsolvable, but Antonio Damasio is convinced that recent findings in neurobiology, psychology, and AI have given us the necessary tools to solve its mystery. Now, he not only elucidates its myriad aspects, but presents his analysis and insights in a way that is faithful to our own intuitive sense of (...) the experience of consciousness. In the 45 brief chapters of the book, he helps us understand the relation between consciousness and mind; why being conscious is not the same as either being awake or sensing; the essential role of feeling; and the biological brain and development of consciousness. He synthesizes the recent findings of various sciences with the outlook of philosophy, and, most significantly, presents his original research which has transformed our understanding of the brain and human behavior. Here is an indispensable guide to understanding consciousness, the fundamental human capacity for informing--and transforming--our experience of the world around us and our perception of our place in it.

Most infant cognitive studies use visual fixation time as the measure of interest. There are, however, some serious methodological and theoretical concerns regarding what these studies reveal about infant cognition and how their results ought to be interpreted. We propose a Bayesian modeling framework which helps address these concerns. This framework allows us to more precisely formulate hypotheses about infants’ cognitive representations, formalize “linking hypotheses” that relate infants’ visual fixation behavior with stimulus complexity, and better determine what questions a given (...) experiment can and cannot answer.

L.S. Vygotsky’s “regulative” account of the development of human thinking hinges on the centralization of “directive” speech acts (commands or imperatives). With directives, one directs the activity of another, and in turn begins to “self-direct” (or self-regulate). It’s my claim that Vygotsky’s reliance on directives de facto keeps his account stuck at Tomasello's level of individual intentionality. Directive speech acts feature prominently in Tomasello’s developmental story as well. But Tomasello has the benefit of accounting for a functional differentiation in directive (...) communication—i.e., in collaborative activity, the command gives way to both the request and informational assertion. Lacking such differentiation, Vygotsky’s account runs the risk of playing to a rather strident conception of the socius, one more Machiavellian than Marxist. (shrink)

This commentary focuses on the importance of attention skills in the development of universal associative learning, and it explains why the centrality of attention in UAL presents a considerable difficulty for the UAL approach. Attentional abilities are not just developmentally related to UAL but are in fact explanatory of UAL. The main problem is that all the types of attention involved in UAL can be dissociated from consciousness. This means that while attention skills for UAL might be necessary for consciousness, (...) they are not sufficient because they can all occur unconsciously. Thus, the possibility that UAL capacities might not be sufficient for consciousness cannot be eliminated, thereby challenging the key claim of the UAL approach. (shrink)

The study of plant signaling and behaviour, whose aim is to address the physiological basis for adaptive behaviour in plants, is a growing and thought-provoking field of research. In this review we discuss relevant studies that try to interpret in a neurocognitive fashion cases in which plants seem to behave similarly to animals. By comparing observations and experiments about plants and animals, we propose a framework composed of three axes in which interactions of living organisms with the world can be (...) represented. The first axis refers to adaptiveness, the second to sensitivity, and the third to sentience. This model allows us to interpret the behaviours of living organisms along a continuum capable of giving a smooth transition from simple to complex responses. In light of this, plants show an excellent adaptiveness, a variable level of sensitivity, and a good degree of sentience (restricted to the immediate perception that something is happening to themselves). Only the organisms with a high degree of sentience can have the basis for developing consciousness. However, even though it is necessary for consciousness, sentience is not sufficient, as it must be associated with a complex functional organization of structures that can support a recursive and synchronized processing of information. So far, plants have been found to completely lack this type of organization. Plants appear to be, therefore, sentient but not conscious. (shrink)

Creativity is intrinsic to Humanities and STEM disciplines. In the activities of artists and engineers, for example, an attempt is made to bring something new into the world through counterfactual thinking. However, creativity in these disciplines is distinguished by differences in motivations and constraints. For example, engineers typically direct their creativity toward building solutions to practical problems, whereas the outcomes of artistic creativity, which are largely useless to practical purposes, aspire to enrich the world aesthetically and conceptually. In this essay, (...) an artist (DHS) and a roboticist (GS) engage in a cross-disciplinary conceptual analysis of the creative problem of artificial consciousness in a robot, expressing the counterfactual thinking necessitated by the problem, as well as disciplinary differences in motivations, constraints, and applications. We especially deal with the question of why one would build an artificial consciousness and we consider how an illusionist theory of consciousness alters prominent ethical debates on synthetic consciousness. We discuss theories of consciousness and their applicability to synthetic consciousness. We discuss practical approaches to implementing artificial consciousness in a robot and conclude by considering the role of creativity in the project of developing an artificial consciousness.

Over the past two decades, Ginsburg and Jablonka have developed a novel approach to studying the evolutionary origins of consciousness: the Unlimited Associative Learning framework. The central idea is that there is a distinctive type of learning that can serve as a transition marker for the evolutionary transition from non-conscious to conscious life. The goal of this paper is to stimulate discussion of the framework by providing a primer on its key claims and a clear statement of its main empirical (...) predictions. (shrink)

This paper addresses what we consider to be the most pressing challenge for the emerging science of consciousness: the measurement problem of consciousness. That is, by what methods can we determine the presence of and properties of consciousness? Most methods are currently developed through evaluation of the presence of consciousness in humans and here we argue that there are particular problems in application of these methods to nonhuman cases—what we call the indicator validity problem and the extrapolation problem. The first (...) is a problem with the application of indicators developed using the differences between conscious and unconscious processing in humans to the identification of other conscious vs. nonconscious organisms or systems. The second is a problem in extrapolating any indicators developed in humans or other organisms to artificial systems. However, while pressing ethical concerns add urgency to the attribution of consciousness and its attendant moral status to nonhuman animals and intelligent machines, we cannot wait for certainty and we advocate the use of a precautionary principle to avoid causing unintentional harm. We also intend that the considerations and limitations discussed in this paper can be used to further analyze and refine the methods of consciousness science with the hope that one day we may be able to solve the measurement problem of consciousness.

Tyler Burge claims in a recent high-profile publication that none of the existing evidence for mental-state attribution by children prior to the age of four or five really supports such a conclusion; and he makes this claim, not just for beliefs, but for mental states of all sorts. In its place, he offers an explanatory framework according to which infants and young children attribute mere information-registering states and teleologically-characterized motivational states, which are said to lack the defining properties of the (...) mental. I argue that Burge’s claims are poorly motivated and irrelevant to the goals of developmental psychology. (shrink)

Identifying which nonhuman animal species are capable of feeling pain is important both for understanding pain mechanisms more generally and for informing animal welfare regulations, particularly in genera that are not yet widely protected. A common way to try to provide evidence of pain experiences is through behavioral indicators. In this paper I use a very simple interventionist approach to experimentation, and the contrast case provided by C. elegans, to argue that behavioral indicators commonly used for identifying pain in nonhuman (...) animals are much less robust than typically presented. Indeed, I argue that many behavioral indicators of pain are invalid as they are currently described. More positively, this analysis makes it possible to identify what valid criteria might look like, and where relevant, to identify existing evidence related to them. Based on this I propose that the best way to make progress on questions around animal pain is to clearly ally them with questions about animal consciousness more generally, and to productively use conceptual and empirical work in both areas to develop more theoretically defensible behavioral indicators.

This paper argues that self-consciousness and associated psychic consciousness emerges as a consequence of a recursive selfdirecting on itself of the cognitive centre in the human brain. The neural mechanisms and circuits underlying self-consciousness appeared and developed during biological evolution as an adaptation that increased the fitness of our social ancestors, chances of their survival, and reproduction. These mechanisms/circuits strengthened the efficiency of individuals in various social relations, enabled separation of 'I' from 'he/she' or 'them' and the formation of firstand (...) higher-order theory of mind, stimulated development of complex, recursive language, facilitated forming temporary coalitions directed to achieve a particular goal, helped to establish social hierarchies, and increased coherence and cooperativity of a social group. The reciprocal reinforcement of the development of the neural network in the brain underlying self-consciousness and of the network of various social relations and aspects was a self-driving process, one of positive feedbacks abundant in anthropogenesis.

Little is known about the time of development of the binocular suppression. In the present study, we evaluated the emergence of binocular suppression in infants by using continuous flash suppression (CFS, Tsuchiya & Koch, 2006). In our experiment, one eye of infants presented with a static face image at one side of the screen, while another eye is presented with dynamic Mondrian patterns in full screen. Adult observers confirmed that the static face image was consciously repressed by the changing Mondrian (...) patterns. If binocular suppression were functional, the infant would not perceive the face as did the adults, and thus would not show any preference in the experiment. However, if binocular suppression in the infants were not yet acquired, they would perceive the face and the Mondrian patterns at the same time, and would thus show preference for the side where the face was presented. The results showed that infants aged 2–3 months, but not those aged 4–5 months, detected the position of the face. Furthermore, this detection was not due to weak contrast sensitivity to the dynamic Mondrian mask. These results indicated that the immature binocular visual system may perceive different images from different eyes simultaneously, and that infants may lose this ability after establishing binocular suppression at 4–5 months of age.

The concept of quantum spontaneity is introduced to provide a non-deterministic, non-indeterministic, and non-random model of consciousness that can accommodate our intuitive sense of self, intentionality, and creativity.

Objective To review the way consciousness is operationalised in contemporary research, discuss strengths and weaknesses of current approaches and propose new measures. Method We first reviewed the literature pertaining to the phenomenal character of visual and self-consciousness as well as awareness of visual stimuli. We also reviewed more problematic cases of dreams and animal consciousness, specifically that of octopuses. Results Despite controversies, work in visual and self consciousness is highly developed and there are notable successes. Cases where experiences are not (...) induced, such as dreams, and where no verbal report is possible, such as when we study purported experiences of octopuses, are more challenging. It is difficult to be confident about the reliability and validity of operationalisations of dreams. Although this is a general concern about the measuring consciousness, it is not a sufficiently severe concern to completely undermine the work reviewed on vision and self-consciousness. It is more difficult to see how the good work on human psychology can be applied to non-human animals, especially those with radically different nervous systems, such as octopuses. Given the limitations of report-based operationalisations of consciousness, it is desirable to develop non-report-based measures, particularly for phenomenal qualities. We examine a number of possibilities and offer two possible approaches of varying degrees of practicality, the first based on combining quality space descriptions of phenomenal qualities and the notion of a “neural activation space” inherited from connectionist A.I., the second being a novel match to target approach Conclusion Consciousness is a multifacted phenomenon and requires a variety of operationalisations to be studied.

Here, I explore the idea that consciousness is something that the brain learns to do rather than an intrinsic property of certain neural states and not others. Starting from the assumption that neural activity is inherently unconscious, the question thus becomes: how does the brain learn to be conscious? I suggest that consciousness arises as a result of the brain's continuous attempts at predicting not only the consequences of its actions on the world and on other agents, but also the (...) consequences of activity in one cerebral region on activity in other regions. By this account, the brain continuously and unconsciously learns to redescribe its own activity to itself, so developing systems of metarepresentations that characterize and qualify the target first-order representations. Such learned redescriptions, enriched by the emotional value associated with them, form the basis of conscious experience. Learning and plasticity are thus central to consciousness, to the extent that experiences only occur in experiencers that have learned to know they possess certain first-order states and have learned to care more about certain states than others. This is what I call the 'radical plasticity thesis'. In a sense, thus, this is the enactive perspective, but turned both inwards and outwards. Consciousness involves 'signal detection on the mind'; the conscious mind is the brain's theory about itself. (shrink)

In this paper, I will give a three-stage analysis of the origin of phenomenal consciousness. The first one has to do with a non-causal stage. The second one has to do with a causal stage. The third one has to do with a correlation stage. This paper is divided into three sections. In section I, I will discuss a non-causal stage which focuses on finite consciousness as an irreducible emergent property—i.e., a simple non-structural property that is unique to the “emergent” (...) level of reality. I will examine currently dominant accounts of the emergence of phenomenal consciousness—which require consciousness to have some sort of causal link to its base level. Those who think of the emergence of consciousness in casual terms, often have in mind, brain complexity as a source of such causality. However, the causal proposal faces two serious empirically supported objections, namely: the gametes problem and the complexity problem, respectively. The first objection deals with conception (i.e., fertilization) and the impossibility of tracking down/spotting the origin of consciousness at any point during the process of the development of a foetus. The second objection focuses on demonstrating that, no amount of analysis of the physical basis of complex brain will unfold anything substantial about the origin of consciousness. Both of these two objections show why the diachronic account of the origin of the phenomenal consciousness is hard to come by. In section II, I will discuss a causal stage which focuses on, how once it emerges, consciousness enters into the domain of causal interaction with brain states. This is the stage where we come across both ‘the explanatory gap problem’ and ‘the hard problem of consciousness.’ In section III, I will discuss the correlation stage which focuses on the manner in which phenomenal consciousness continues to co-exist with its physical base (e.g., brain). To show this, I will discuss the notion of correlation and its relation to causation. The upshot of my discussion in the above three sections will constitute the view I call the non-causal spontaneous emergence of phenomenal consciousness. According to the view I am proposing, there is no causal-link between strongly emergent property (in this case, consciousness) and its base level—although the base level (as far as we know) serves as a sufficient condition (but not as a necessary condition) for its emergence. In light of this, I conclude this paper by claiming that phenomenal consciousness is a strongly emergent property. (shrink)

Longlisted for the PEN/E.O. Wilson Literary Science Writing Award A leading neuroscientist offers a history of the evolution of the brain from unicellular organisms to the complexity of animals and human beings today Renowned neuroscientist Joseph LeDoux digs into the natural history of life on earth to provide a new perspective on the similarities between us and our ancestors in deep time. This page-turning survey of the whole of terrestrial evolution sheds new light on how nervous systems evolved in animals, (...) how the brain developed, and what it means to be human. In The Deep History of Ourselves, LeDoux argues that the key to understanding human behavior lies in viewing evolution through the prism of the first living organisms. By tracking the chain of the evolutionary timeline he shows how even the earliest single-cell organisms had to solve the same problems we and our cells have to solve each day. Along the way, LeDoux explores our place in nature, how the evolution of nervous systems enhanced the ability of organisms to survive and thrive, and how the emergence of what we humans understand as consciousness made our greatest and most horrendous achievements as a species possible.

Among psychologists, it is widely thought that infants well under age 3, monkeys, apes, birds, and dogs have been shown to have rudimentary capacities for representing and attributing mental states or relations. I believe this view to be mistaken. It rests on overinterpreting experiments. It also often rests on assuming that one must choose between taking these individuals to be mentalists and taking them to be behaviorists. This assumption underestimates a powerful nonmentalistic, nonbehavioristic explanatory scheme that centers on attributing action (...) with targets and on causation of action by interlocking, internal conative, and sensory states. Neither action with targets, nor conative states, nor sensing entails mentality. The scheme can attribute conative states and relations, efficiency, sensory states and relations, sensory retention, sensory anticipation, affect, and appreciation of individual differences. The scheme can ground explanations of false belief tests that do not require infants or nonhuman animals to use language. After the scheme is explained and applied, it is contrasted with other, superficially similar schemes proposed in the literature---for example, those of Gergely and Csibra, Wellman and Gopnik, Perner and Roessler, Flavell, and Apperly and Butterfill. Better methods for testing are briefly discussed. (shrink)

In English we use the word “invention” in two ways. First, to mean a new device or process developed by experimentation, and designed to fulfill a practical goal. Second, to mean a mental fabrication, especially a falsehood, designed to please or persuade. In this paper I argue that human consciousness is an invention in both respects. First, it is a cognitive faculty, evolved by natural selection, designed to help us make sense of ourselves and our surroundings. But then, second, it (...) is a fantasy, conjured up by the brain, designed to change the value we place on our existence. (shrink)

The article discusses the problem of self-consciousness, which was first articulated by G. Fichte, and which refers to explaining a conscious self-reference without falling into an infinite regression when self-consciousness is implied but not explained. Analyzing S. Shoemaker’s linguistic approach to self-consciousness, the author asserts that the key feature of self-consciousness is a conscious self-reference. However, after considering Shoemaker’s arguments, the author claims impossibility of solving the problem of self-consciousness solely by means of a linguistic analysis. Therefore, the author refers (...) to two bottom-up proposals aiming to solve this issue: the approach of non-conceptual forms of self-consciousness developed by J. Bermúdez and the conception of self-consciousness pre-reflective form coined by D. Zahavi. The article states inadequacies in both approaches and asserts the need to identify self-consciousness in non-intentional, non-semantic, and non-mental concepts - that is, in a naturalistic way that meets the requirements to naturalism put forward by L. Baker. For this, the author suggests referring to representationalism, in particular to, the works of F. Dretske, and trying to ground the theory of self-consciousness in his statement that representations do not require «self», a principle that spontaneously organizes mental activity and carries out all intentional acts. The author concludes that the approach of Dretske avoids an endless regression or circular way of explanation. However, the very project of naturalization of self-consciousness, based on a non-linguistic, naturalized form of representation of a cognitive system that does not contain «self», can not exist without taking into account the first-person perspective. One of the possible solutions to this problem is the assumption of a metaphysical relation everyone has to himself. However, the author stresses the need for further clarification and agreement with the theses of strong representationalism. (shrink)

: The development of the interdisciplinary areas of cognitive, affective and action neurosciences contributes to the identification of neurobiological bases of conscious experience. The structure of consciousness was philosophically conceived a century ago as consisting of a subjective pole, the bearer of experiences, and an objective pole composed of experienced contents. In more recent formulations, Nagel refers to a “point of view”, in which qualitative experiences are anchored, while Velmans understands that phenomenal content is composed of mental representations “projected” to (...) the space external to the brains that construct them. In Freudian psychology, the conscious mind contains a tension between the Id and the Ego. How to relate this bipolar structure with the results of neuroscience? I propose the notion of projection [also used by Williford et al. ] as a bridge principle connecting the neurobiological systems of knowing, feeling and acting with the bipolar structure. The projective process is considered responsible for the generation of the sense of self and the sense of the world, composing an informational phenomenal field generated by the nervous system and experienced in the first-person perspective. After presenting the projective hypothesis, I discuss its philosophical status, relating it to the phenomenal and high-order thought approaches, and a mathematical model of projection. Eight ways of testing the status of the projective hypothesis are briefly mentioned. Resumo: O desenvolvimento de áreas interdisciplinares das neurociências, contribui para a identificação das bases neurobiológicas da experiência consciente. A estrutura intrínseca da experiência consciente foi filosoficamente concebida há um século como consistindo de um pólo subjetivo, o portador de experiências, e um pólo objetivo, composto dos conteúdos experimentados. Em formulações mais recentes, Thomas Nagel refere-se a um “ponto de vista”, no qual experiências qualitativas são ancoradas, enquanto Max Velmans entende que o conteúdo fenomenal é composto de representações mentais “projetadas” para o espaço externo ao cérebro que as constrói. Na psicologia freudiana, a mente consciente contém uma tensão entre o Id e o Ego. Como relacionar esta estrutura bipolar com os resultados da neurociência? Proponho a noção de projeção como princípio-ponte, conectando os sistemas neurobiológicos do saber, sentir e agir com a estrutura bipolar. O processo projetivo é considerado responsável pela geração do sentido do eu e do sentido do mundo, compondo um campo fenomenal informacional gerado pelo sistema nervoso e vivenciado na perspectiva da primeira pessoa. Após apresentar a hipótese projetiva, discuto seu status filosófico, relacionando-o às abordagens fenomenológicas, à teoria do pensamento de ordem superior e ao modelo matemático da projeção. Oito maneiras de testar o status da hipótese projetiva são brevemente mencionadas. (shrink)

The article regards the age peculiarities of the development of personality’s self-consciousness in youth. -/- The conducted theoretical analysis and empirical research contribute to the definition of the following features of the formation of personality self-consciousness in youth: -/- – strengthening the integrative tendency in this process, which leads to an increase in the level of cognitive complexity, differentiation, integrity, and hierarchy of the “Self-image”, as well as the emergence of a holistic, integrated “I”; -/- – the ability of self-awareness (...) as the highest form of self-knowledge, due to the higher level of development of intelligence and the individuals thinking; -/- – increase of the level of awareness of the personality of their own experiences, self-attitude, and selfesteem, which contributes to the growth of interest in his/her “I”; -/- – actualization of the process of development of personal and social self-identity (self-determination) of youth; -/- – intensification of formation of the system of value orientations as a psychological basis for the development of personality’s self-consciousness; -/- – an ability to make informed decisions in various spheres of life (social, professional, personal, etc.), which is the evidence of becoming a socially mature person; -/- – psychological mechanisms for the development of the youth’s self-consciousness is self-reflection, identification, and separation; -/- – a pivotal object of self-reflection is the relationship with significant others and their own life position; the object of identification presents socially valuable qualities of others, which promotes the assimilation of social norms; due to separation of the acquired norms of behavior, value orientations and motives become individualized. -/- The identified features are important for the psychological and pedagogical theory and practice.

This chapter aims to show that the scientific approach to nature, in particular to animals and human beings, is not sufficient to understand the sense of their organism, because it does not explain the sense of their life. Furthermore for the same reason it is not possible to affirm that the human being is a machine, or that a machine could develop so that it can become like—or sometimes as the same in—a human being. To support this assumption I assume (...) a phenomenological attitude following the analyses proposed by Edmund Husserl and some of his scholars. (shrink)

This paper tells the story of consciousness from each of the three 'person' perspectives of the English language, with the author arguing for the equally fundamental social and personal bases of human consciousness. The 'lived' second-person position of ecological psychology is the starting point for the organic, yet socially embedded, consciousness of the non-symbolic human infant. First- and third-person positions are 'reflective' sociohistorical perspectives enabled by the development of symbolic functioning. The paper presents Llinás's compelling evolutionary account but supplements this (...) third-person narrative to do justice to the profound transformation of conscious experience in the human species. Prefacing its account of consciousness from a first-person perspective, the paper argues for a developmental model that privileges both the organic and the sociohistorical bases of consciousness. Our introspections may not tease apart these influences, but they must be acknowledged as we consider what Gelernter refers to as the 'tides of our minds'. (shrink)
