Microalgae in the wild often form consortia with other species promoting their own health and resource foraging opportunities. The recent application of microalgae cultivation and deployment in commercial photobioreactors (PBR) so far has focussed on single species of algae, resulting in multi-species consortia being largely unexplored. Reviewing the current status of PBR ecological habitat, this article argues in favor of further investigation into algal communication with conspecifics and interspecifics, including other strains of microalgae and bacteria. These mutualistic species form the (...) ‘phycosphere’: the micro-environment surrounding microalgal cells, potentiating the production of certain metabolites through biochemical interaction with cohabitating microorganisms. A better understanding of the phycosphere could lead to novel PBR configurations, capable of incorporating algal-microbial consortia, potentially proving more effective than single-species algal systems.

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 entity as existing, like conspecifics were represented. But the same identification process also took place with endangered and dying conspecifics. And this has produced a huge anxiety increase, source of important mental sufferings that our ancestors had to limit. 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 identifications with conspecifics, and by this also stopping a possible evolution toward self-consciousness. Such anxiety limitation process has 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. With these tools accelerating the evolution of our lineage toward our human mind. The proposed pan/homo split 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. 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.

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 performance of reflectivity of self-consciousness is traditionally associated to the subject turning its consciousness of objects to its own entity. But such process introduces concerns of circularity and of infinite regress. To avoid them philosophers have postulated a “pre-reflective self-consciousness” understood as a “state of consciousness that is immediately aware of itself, unmediated by reflections”. We propose here that an evolutionary scenario for self-consciousness can introduce reflectivity as a natural performance, bringing pre-reflective self-consciousness to be reconsidered. The evolutionary scenario (...) starts when our ancestors were capable to manage representations while also being able to partly identify with their conspecifics represented as existing in the environment. These identifications have allowed our ancestors to merge the representations they had of parts of themselves with the corresponding representations they had of their conspecifics. These mergers have progressively led our ancestors to begin representing themselves as entities existing in the environment, like conspecifics were represented. Such process has produced an elementary reflectivity and has provided our ancestors with an "ancestral self-consciousness". And thinking about the represented entity has led our ancestors to self-consciousness as object and as subject. Reflectivity can then be considered as a natural performance of self-consciousness. And postulating a pre-reflective self-consciousness may need to be re-addressed. (shrink)

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)

This paper addresses the foundations of Teleological Individualism, the view that organisms, even non-sentient organisms, are goal-oriented systems while biological collectives, such as ecosystems or conspecific groups, are mere assemblages of organisms. Typical defenses of Teleological Individualism ground the teleological organization of organisms in the workings of natural selection. This paper shows that grounding teleological organization in natural selection is antithetical to Teleological Individualism because such views assume a view about the units of selection on which it is only (...) individual organisms that are units of selection. However, none of the Conventionalist, Reductionist, or Multi-Level Realist theories serve to justify such an assumption. Thus, Teleological Individualism cannot be grounded in natural selection.

In this paper, I argue that nonhuman animals can be subject to epistemic injustice. I consider Miranda Fricker’s (2007) account of the nature of the harm of epistemic injustice and highlight that it requires that a knower be invested in being recognized as a knower. I argue that a focus on know-how, rather than testimony or concepts for self-understanding and communication, can serve to highlight how nonhuman animals can suffer epistemic injustice without an investment in recognition, by focusing on distributive (...) justice concerning epistemic goods. Drawing from work in animal ethology and movement ecology, I argue that human interruption of animal lifeways has negative downstream effects on nonhuman animals’ ability to acquire ‘answers’ to ‘questions’ they have an interest in answering: namely, acquiring both true beliefs about conspecifics and their environment, as well as acquisition of behaviors and skills that enable everyday successful coping, and that these interruptions can constitute epistemic injustice.

Only our lineage has ever used trackways reading to find unseen and unheard targets. All other terrestrial animals, including our great ape cousins, use scent trails and airborne odors. Because trackways as natural signs have very different properties, they possess an information-rich narrative structure. There is good evidence we began to exploit conspecific trackways in our deep past, at first purely associatively, for safety and orienteering when foraging in vast featureless wetlands. Since our own old trackways were recognizable they (...) were self-mirroring, triggering memories of what we had been up to in the past. Using them to find our way back to the band when temporarily lost or to re-find a resource-rich area discovered the day before enabled optimal foraging. Selection for daily reiteration of one’s own old trackways therefore triggered the evolution of what is distinctive about human cognition: the autobiographical or narrative (episodic) faculty for imaginative self-projection. This faculty enabled us to glean useful social information from the stories “told” by other band members’ old trackways, and created spin-off capacities for fast-track social learning. Resultant increases in socioecological complexity then created positive selective feedback loops for further entrenchment. Incrementally we became the ultra-social narrative-minded ape, capable of creating cumulative culture. (shrink)

This chapter explores the suggestion that early attachment underpins the human capacity for empathy, and that empathy, in turn, is a condition of moral competence. We are disposed by nature to seek intimacy with our human conspecifics: the securely attached child learns that, whatever perils the world may hold, his well-being is shielded within the private sphere of personal intimacy. But why should secure attachment also favour—as it does—recognition of moral obligations towards those with whom we have no special standing (...) and share no personal destiny—recognition that the claims of persons as such merit our attention and regard? One answer to this question looks beyond the fact of secure attachment to a further psychological capacity, our capacity for empathy: secure attachment promotes susceptibility to empathy, and an appropriate susceptibility to empathy is a condition of basic moral competence. The chapter proposes that the deeper and more persisting significance of empathy to morality can be understood from a developmental perspective. Looking to mentalization-based attachment theory allows us to understand how empathic mirroring enters into our earliest intimate, interactions with other persons, securing our default commitment to recognizing their reality as bound up with our own. In this way, empathy constitutes one of the natural foundations on which the more complex architecture of moral experience is constructed. Attachment theory helps us to understand the indispensable role empathy plays at the beginning of the circuitous road to virtue. (shrink)

In IVP50S, Spinoza claims that “one who is moved to aid others neither by reason nor by pity is rightly called inhuman. For (by IIIP27) he seems to be unlike a man” (IVP50S). At first blush, the claim seems implausible, as it relies on the dubious assumption that beings will necessarily imitate the affects of conspecifics. In the first two sections of this paper, I explain why Spinoza accepts this thesis and show how this claim can be made compatible with (...) his account of representation. In the third and final section I offer an auxiliary defense of the thesis, showing that, according to Spinoza, to be human is to sociable, and sociability depends on the imitation of the affects.

Content nonconceptualism and State conceptualism are motivated by different readings of what I want to call here Bermúdez’s conditions on content-attribution (2007). In one read- ing, what is required is a neo-Fregean content to solve problems of cognitive significance at the nonconceptual level (Toribio, 2008; Duhau, 2011). In the other reading, what is required is a neo-Russellian or possible-world content to account for how conspecifics join attention and cooperate, contemplating the same things from different perspectives in the same perceptual field. (...) The solution to this apparent contradiction is the rejection of the real content view and the adherence to what I call here Content-pragmatism: there is no such thing as the content of experience. According to content pragmatism, “proposition” is not as real as a mental state, but rather, it is a term of art that semanticists use, as a matter of theoretical convenience, to classify mental states. What follows from Content-pragmatism is Content- pluralism: there are so many contents that are required to meet Bermúdez’s condition on content attribution. Because both criticism and the defense of State conceptualism overlook the real scope of Bermúdez’s condition on content attribution, they are ineffective. In this paper, I will argue that the opposition between State and Content nonconceptualism is a real one, but only a relative one, that is, relative to the opposite constraints to be met. If we want to solve the problems of cognitive significance, the best we can do is to let the content of experience be modeled as neo-Fregean content, namely, a compound of nonconceptual modes of presentation of objects and properties. In this case, Content-nonconceptualism prevails. In contrast, if we want to account for how conspecifics join attention to the same entities in the same perceptual field from different perspectives, the best we can do is let the content of experience be modeled either as a structured Russellian proposition or as a function from possible worlds to truth-values. In this case, State-nonconceptualism prevails. (shrink)

I argue that death can be (and sometimes is) bad for cattle because it destroys relationships that are valuable for cattle for their own sake. The argument relies on an analogy between valuable human relationships and relationships cattle form with conspecifics. I suggest that the reasons we have for thinking that certain rich and meaningful human relationships are valuable for their own sake should also lead us to think that certain cattle relationships are valuable for their own sake. And just (...) as death is bad for us when it destroys our valuable relationships, so death is bad for cattle when it destroys their valuable relationships. This argument is important because it pinpoints something that is bad about death for cattle that is overlooked by popular accounts of the badness of death for non-human animals that focus exclusively on the impact of death on lifetime well-being levels. Thus, the argument reveals an overlooked moral cost of some of our farming practices. (shrink)

The theory of epistemic vigilance posits that -- to quote the eponymous paper that introduced the theory -- “humans have a suite of cognitive mechanisms for epistemic vigilance, targeted at the risk of being misinformed by others." Despite the widespread acceptance of the theory of epistemic vigilance, however, I argue that the theory is a poor fit with the evidence: while there is good reason to accept that people ARE vigilant, there is also good reason to believe that their vigilance (...) is NOT epistemic. Rather, the evidence actually supports an alternative theory, one that I dub the theory of "Machiavellian vigilance": humans have a suite of cognitive mechanisms for Machiavellian vigilance, targeted at tracking others' relative social status and maintaining or enhancing one's own status. The evidence against epistemic vigilance stems from three sources: (a) data demonstrating that people are terrible at detecting honesty or competence, (b) data demonstrating that our vigilance is phylogenetically prior to the development of homo sapiens, and therefore was not designed to be sensitive to linguistic communication, and (c) data demonstrating that people's sources of information are distributed, and not detectable through individual vigilance. The evidence in favor of Machiavellian vigilance is the mirror image of the evidence against epistemic vigilance: (a) data demonstrating that people are very accurate at detecting status, (b) data demonstrating that social species, including bonobos and chimps, track the social status of their conspecifics, and (c) data demonstrating that people can quickly track status even in new social groups.

The paper begins with a description of a grey seal performing conspecific infanticide. The paper then gives an account of “nobleness” and “brutishness.” Roughly, a behavioural-disposition is noble/brutish if it is one that would be a moral virtue/vice if the possessor of the behavioural-disposition were a moral agent. The paper then advances two pairs of axiological claims. The first pair of claims is that nobleness is good and that brutishness is bad. The second pair of claims is about an (...) axiological interaction between nobleness/brutishness and well-being. That any non-human animal lacks well-being is bad. Yet, it is worse that a noble non-human animal lacks well-being, and not so bad that a brutish non-human animal lacks well-being. Lastly, the paper discusses some potential moral implications of these axiological claims, for instance that factory farming is especially wrong because it causes noble non-human animals to lack well-being.

We defend a realistic attitude towards biological species. We argue that two species are not different species because they differ in intrinsic features, be they phenotypic or genomic, but because they are separated with regard to gene flow. There are no intrinsic species essences. However, there are relational ones. We argue that bearing a gene flow relation to conspecifics may serve as the essence of a species. Our view of the species as a Gene-Flow Community differs from Mayr’s definition of (...) the species as a reproductive community. In a reproductive community, each organism is able to successfully reproduce with each other. However, there are species in which geographically distant organisms lost their ability to successfully reproduce, due to strong genetic adaptations to the respective local environmental conditions. Despite this loss of the ability to mutually reproduce, they are still bound by gene flow via continuous intermediate populations. This replacement of Mayr’s notion of an interbreeding potential as a criterion for species membership has important implications for the treatment of populations in allopatry and sympatry. (shrink)

We all agree that our human minds are results of primate evolution. We humans are self conscious. The separation of our human lineage from the chimpanzee one began about 7MY ago (pan homo split). Specificities of human self consciousness have been created during that time. Besides interesting approaches differing from the one proposed here [1], little is known about how these specificities came up [2, 3]. We propose here to address that subject with an evolutionary scenario using meaningful representations, identifications (...) with conspecifics and anxiety management. Taking the beginning of the pan-homo split as a starting point we look at how an evolutionary scenario could have led to our present human self consciousness as object and as subject. An evolutionary anxiety is highlighted as having been a key contributor to the evolutionary scenario with perspectives on a possible future of self consciousness. Human self consciousness is defined here as the meaningful representation of one’s own entity, with the capability to think and talk about it. The evolutionary scenario proposed here is an extension of a previous version [11] that uses an evolution of meaningful representations introduced in previous works [8]. The scenario starts with two types of meaningful representations carried by our non self-conscious pre-human ancestors: representations of parts of themselves (seen hands, heard shouting, actions, …) and representations of conspecifics as entities existing in the environment. The next step uses elementary versions of inter-subjectivity and of identifications with conspecifics that our primate ancestors were capable of. It is proposed that these performances have brought the two types of representations to merge and bring our ancestors to progressively represent their own entity as existing in the environment like conspecifics were represented. We consider such evolutionary approach as introducing an elementary form of self consciousness as object and a s subject, both coming in together. We group them into an “ancestral self consciousness” which was to evolve into our human self consciousness [4]. Such approach avoids the need of a pre-reflective self consciousness [7]. The scenario considers that such identifications took place also with suffering or dying conspecifics. These identifications were sources of specific new fears and anxieties that the scenario groups in an “evolutionary anxiety”, source of important mental sufferings that our ancestors had to limit. Different possibilities were available for that. The scenario proposes that the chimpanzee lineage may have limited what was an unbearable mental suffering by stopping the development of identifications with conspecifics, and by this also stopping a possible evolution toward self-consciousness. This would have led to today chimpanzees. On the other side, our human lineage may have developed anxiety limitation tools like caring, pleasure, anticipation, communication and imitation; such tools also favoring the evolution of our lineage toward human minds . This is illustrated in the scenario by the introduction of an ”evolutionary engine”. In addition, the capacity for anticipation attached to self consciousness has amplified the evolutionary anxiety, leading it to become an overall “ancestral anxiety” which is still present and active in our human minds (with anxiety limitations as a key constraints to satisfy). The many anxiety limitation processes introduced in our lineage during the pan homo split were interrelated. Many came up in addition to the few ones listed here above. Most remain in our human minds at an unconscious level and are active in our everyday lives, much more than assumed so far. Considering a possible future of human self consciousness, nothing tells that human evolution is terminated. Also, the evolutionary scenario introduces the possibility for some anxiety limitation processes to be sources of evil behaviors, more precisely related to a possible pleasure procured by the suffering of others [9]. That (disturbing) background could introduce a better understanding of human mind, and so be an entry point to its future in terms of potential improvements of human nature. The scenario also introduces an evolutionary nature of reflectivity [10] which can question the philosophical need for a pre-reflective self consciousness. Such perspective can also introduce a naturalization of introspection, and then allow to consciously question the nature and content of our mental states. This could open a path for a tentative naturalization of the “what it is like” question for humans and make available an evolutionary link between self consciousness and phenomenal consciousness. A last point to highlight is that the proposed evolutionary scenario uses performances of life like intersubjectivity. This brings to note that a full understanding of the proposed scenario needs an understanding about the nature of life which is not available today. A lot remains to be done on these subjects. Continuations are introduced. (shrink)

People espousing human moral equality encompassing every conspecific have been unumbrageous being labeled ‘speciesists’ and likened to Nazis and Klansmen, despite the insult’s being indefensible, and, if meant seriously, enraging. Perhaps their equanimity is unruffled because anti-speciesist acquaintances are remarkably chummier with them than with real racists. -/- Anti-speciesists confuse two questions: (1) Is the bare fact of an individual’s being a human in itself a reason for us humans to deal with it as we'd like to be dealt (...) with? (2) Have we enough reason, apart from human well-being, to impose on each other protections of other animals? Speciesism, perspicuously specified, says ‘yes’ to (1) and nothing about (2). World-wide, human fantasy is filled with nonhuman persons, alien morally accountable agents, thought worthy of being treated as we would wish to be treated, or better. The idea of human equality is consistent with both rapaciously using animals and radical animal protectionism. We meat-eaters discount animal interests, not because they’re nonhuman, but because we know no compelling reason to count them more. -/- Anti-speciesist literature is surveyed and seen to specify ‘speciesism’ capriciously. Terminology aside, anti-speciesist criticisms are specious. Anti-speciesists hope to shift the justificatory burden by denying species membership any moral relevance, but that denial cannot motivate their protectionism. Their ad hominem dismissal of speciesism as a self-serving prejudice is unsustainable. Their avowed inability to imagine any justification of speciesism is hardly probative. Their alleged refutations are baldly question-begging assertions of theses of hallowed ethical theories speciesism denies. They derive anti-speciesism from “anti-biologism” (a radical denial of any biological relation’s having any intrinsic moral relevance), which is fallaciously extrapolated from anti-racist and anti-sexist ideas. Appeals to taxonomical controversies glibly and disingenuously assume the relevance of those controversies, which anti-biologism denies. (shrink)

Animal liberationists call speciesism their enemy, but speciesism, perspicuously specified, says only that being human is sufficient for having our moral status. No one thinks it necessary. Throughout history, people have imagined alter-specifics, like the crowd at a Star Wars cantina, whom they’d recognize as their moral equals. Speciesism says nothing about our treatment of nonhumans. Speciesism’s historic popularity justifies presuming it true, a presumption buttressed by the absence of sound objections to it when properly understood. Its rationality is explained (...) by combining two ideas. First, universalizations of our reasons require some category of self-identification. Second, our primary category of self-identification is our key concept for understanding ourselves biologically, metaphysically, psychologically and socially, namely our species concept. We’re rationally bound to conspecifics by the relational “accident” of their essence being our own. (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.

In this thesis I present a new paradigm in human evolutionary theory: the relevance of track-ways reading (TWR) to the evolution of human cognition, culture and communication. Evidence is presented that strongly indicates hominins were exploiting conspecific track-ways 4 million years ago. For a non-olfactory ape that was a specialized forager in open, featureless wetland environments, they were the only viable natural signs to exploit for safety, orienteering, and recognizable social markers. Due to the unique cognitive demands of reading (...) track-ways, as compared to scent-trails all other animals use to find each other and preferred prey species, social TWR triggered the evolution of a unique faculty for narrative elsewhere-and-when cognition in the hominin mind. Two million years later, this narrative faculty was entrenched enough to enable the rather sudden ‘explosion’ of co-operative Oldowan Lithic Culture that began at 2.6mya. This cultural adaptation was a highly successful response to catastrophic environmental change. Thereafter selection for encephalization to increase neural capacity to store and co-operatively exploit socio-ecological knowledge gained from the hominin narrative faculty (via co-evolving, increasingly efficient modes of intentional communication) drove all further biological and cultural developments in the hominin trajectory towards H.sapiens and behavioural modernity.

We humans experience ourselves as objects and as subjects. The distinction initiated by Kant between consciousness of oneself as object and consciousness of oneself as subject was a strict one. The rigidity of that distinction has been challenged by philosophers from the continental and the analytic traditions [1]. From another perspective, researches about animal self-awareness are widening the horizon of studies relative to the nature of self-consciousness [2]. These various perspectives introduce the interest about addressing consciousness of oneself as object (...) and as subject in an evolutionary background. We propose here to follow that path by using an existing scenario about the evolutionary nature of self-consciousness based on evolutions of representations and of inter-subjectivity [3, 4]. The scenario presents an evolutionary approach that can introduce self-consciousness as an acting body and self-consciousness as a thinking and feeling entity. These two aspects of self-consciousness are then compared to consciousness of oneself as object and as subject. The scenario proposes that an evolution of inter-subjectivity brought our pre-human ancestors to reach the capability of identifying with their conspecifics. This process coupled with an evolution of representations led our ancestors to build up representations of themselves as entities existing in the environment, like the conspecifics they identified with were represented. As conspecifics were perceived as existing and acting in the environment, identifying with them led to an elementary version of self-consciousness as an acting body, close to self-consciousness as object. Also, as different conspecifics could display very different behaviors like dominant or submitted, it was not possible to identify with them spontaneously. Knowing and understanding one's own identity as perceived by other members of the group was necessary for a pertinent identification with conspecifics. Such need to think about one's own characteristics and identity introduced self-consciousness as a thinking and feeling entity, close to an elementary version of self-consciousness as subject. In addition, the mental states of the thinking and feeling subject monitoring the actions of the body object address the common evolutionary source for consciousness of oneself as object and as subject. We present here that evolutionary approach to consciousness of oneself as object and as subject with the corresponding phylogenetic outcomes relative to the mind-body problem. Continuations are proposed. (shrink)

Though this volume is a bit dated, there are few recent popular books dealing specifically with the psychology of murder and it’s a quick overview available for a few dollars, so still well worth the effort. It makes no attempt to be comprehensive and is somewhat superficial in places, with the reader expected to fill in the blanks from his many other books and the vast literature on violence. For an update see e.g., Buss, The Handbook of Evolutionary Psychology 2nd (...) ed. V1 (2016) p 265, 266, 270–282, 388–389, 545–546, 547, 566 and Buss, Evolutionary Psychology 5th ed. (2015) p 26, 96–97,223, 293-4, 300, 309–312, 410 and Shackelford and Hansen, The Evolution of Violence (2014).

Though this volume is a bit dated, there are few recent popular books dealing specifically with the psychology of murder and it’s a quick overview available for a few dollars, so still well worth the effort.

Theories have been formulated to address the problem of evil [“The concept of Evil”. Stanford Encyclopedia of Philosophy]. We look here at a possible origin of human evil in pre-human times by using an evolutionary scenario for self-consciousness based on identifications with conspecifics [“Proposal for an evolutionary approach to self-consciousness”. Menant 2014]. The key point is that these identifications have also taken place with suffering or endangered conspecifics, thus creating in the minds of our ancestors a huge anxiety increase, a (...) mental pain unbearable if not limited. To limit it our ancestors could have reduced the sufferings and dangers, or reduced the identification, or limited the conspecificity. Reducing the sufferings and dangers was straightforward as it also brought in evolutionary advantages (collaboration, imitation, communication, ToM, ...), with some pleasant feeling coming with the reduction of anxiety. But the two other possibilities may have produced very different outcomes. Reducing the identifications and limiting the conspecificity did reduce the mental pain and correspondingly produce some pleasure. But it has also lowered the emotional attachment to conspecifics as well as the care given to them. Conspecifics were then left alone with their sufferings. And as the process led to less mental pain, our ancestor were naturaly led to associate some pleasure to these sufferings of conspecifics. All this may have introduced in the mind of our ancestors the possibility to reduce anxiety and mental pains also by accepting and valorizing the sufferings of others, thus making evil deeds a potential source of pleasure. We propose these mechanisms as possible sources of psychology of evil in human evolution. These mechanisms now belong to our human nature where evil projects can become a means for limiting the unconscious anxiety present in our human minds. Such positioning of self-consciousness and human evil under a common evolutionary nature is new and needs more developments. Continuations are proposed. (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)

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 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)

Representing oneself as an existing entity and having intense fear of the unknown are human specificities. Self-consciousness and anxiety states are characteristics of our human minds. We propose that these two characteristics share a common evolutionary history during which they acted in synergy for the build-up of our human minds. We present that perspective by using an evolutionary scenario for self-consciousness in which anxiety management plays a key role. Such evolutionary background can introduce new relations between philosophy of mind and (...) psychology. The proposed evolutionary scenario starts at the Pan-Homo split time (about 6my ago) when our pre-human ancestors were able to manage representations while also being able to partly identify with their conspecifics. These identifications allowed our ancestors to merge the representations they had of parts of themselves with the corresponding representations they had of their conspecifics. The scenario proposes that such merger has led our ancestors to progressively build up a representation of their own entity as existing in the environment, like conspecifics were represented as existing. This evolutionary process is considered in the scenario as the source of an ancestral form of self-consciousness. The same process has also produced identifications with suffering or endangered conspecifics which have created in the minds of our ancestors some new anxieties coming in addition to the animal ones. The resulting psychological sufferings had to be limited for evolution to continue. The tools developed to that end by our ancestors (caring, collaboration, communication, ToM, ...) have also procured significant evolutionary benefits with positive feedbacks on identifications. Overall, the evolutionary scenario proposes that the combination of the anxiety management processes with the evolution toward self-consciousness has created an evolutionary engine that has accelerated the coming up of our human self-consciousness. As a result, our today human minds contain important anxieties interwoven with an evolutionary nature of self-consciousness. Such perspective brings to consider that many of our mental states may be unconsciously guided by these evolutionary sourced anxieties (which are still to be clearly understood). Corresponding anxiety management processes are then key contributors to our human feelings and motivations, and to our interpersonal relationship. For instance, the role of Pascalian type diversions can be understood as keeping consciousness away from psychological sufferings produced by too anxious mental states. Also, part of our human sexuality developed during human evolution can be considered as a multidimensional escape and refuge from anxiety. This also brings to look at our psychological well-being and to our mental health as much more related to anxiety management than assumed so far. Dis-functioning of anxiety management processes can then be source of mental disorders and illnesses. On that subject the evolutionary scenario proposes that avoidances of too anxious mental states can lead to evil behaviors. These subjects need more developments. Possible continuations are introduced. (shrink)

The nature of human mind has been an open question for more than 2000 years and it is still today a mystery. There has been during the last 30 years a renewed interest from science and philosophy on that subject. Among the existing research domains is neurophilosophy, an interdisciplinary study of neuroscience and philosophy looking at neuronal aspects of access consciousness, of phenomenal consciousness and at functional aspects of consciousness. We propose here to look if self-consciousness could have a place (...) in neurophilosophy by using an existing evolutionary scenario that can introduce possible links between neural processing and some aspects of self-consciousness. The scenario is about an evolutionary nature of self-consciousness where evolutions of inter-subjectivity and meaningful representations may have led our ancestors to identify with their conspecifics. The scenario proposes that this process has brought our pre-human ancestors to represent themselves as existing entities like the conspecifics they identified with were represented. Such a representation of oneself as an existing entity may have created an elementary version of self-consciousness that we name “ancestral self-consciousness”. But identification with suffering or endangered conspecifics has also produced an important anxiety increase. To limit that anxiety our ancestors have developed mental states and behaviors like caring, imitation communication and simulation. These performances have introduced evolutionary advantages leading to an evolutionary engine that has favored the development of ancestral self-consciousness toward our human self-consciousness. We begin by presenting a model for the generation of meaningful information based on a system submitted to an internal constraint (the Meaning Generator System). We use that model to introduce meaningful representations as networks of meaningful information. We then present the evolutionary scenario for self-consciousness that uses meaningful representations and the performance of inter-subjectivity. The scenario leads to propose two links between self-consciousness and neural processes: mirror-neurons as neural introduction to inter-subjectivity and self-consciousness as neural computation on meaningful representations. Possible continuations are highlighted. (shrink)

Anxiety is a main contributor to human psychological sufferings. Its evolutionary sources are generally related to alert signals for coping with adverse or unexpected situations [Steiner, 2002] or to hunter-gatherer emotions mismatched with today environments [Horwitz & Wakefield, 2012]. We propose here another evolutionary perspective that links human anxiety to an evolutionary nature of self-consciousness. That approach introduces new relations between mental health and human mind. The proposed evolutionary scenario starts with the performance of primate identification with conspecifics [de Waal (...) 1998, 2008]. It is assumed that the evolution of that identification brought our ancestors to represent themselves as entities existing in the environment, like conspecifics were represented as existing in the environment. We consider that this process has implemented in the mind of our ancestors some first elements of self-consciousness [Menant 2014a]. But the same process has also produced new sufferings coming from identification with suffering or endangered conspecifics. In addition, the emerging performance of self-focus brought in the new feeling of being a suffering entity. We consider that all these new sufferings have created in the mind of our primate ancestors a huge anxiety increase, unbearable if not limited. Among the options available to limit that anxiety increase we focus on two of them that may have taken place. The first was a withdrawal from the process. Some primates may have simply rejected the evolution of identification (and with it self-consciousness). This may have led them to an ecological niche resulting in our today great apes. The second option was about limiting the causes of sufferings and taking advantage of possible resulting evolutionary benefits. This may have been achieved by developing performances like imitation, communication, simulation, synergy and ToM. Added to a positive feedback on identification these performances may have initiated an evolutionary engine that has accelerated the evolution toward human self-consciousness. That option is characterized by an early build up of anxiety limitation processes in an evolutionary nature of our human self-consciousness. This option corresponds to a human specificity and introduces anxiety management and self-consciousness as sharing a same evolutionary story. The build up of these anxiety management processes is now buried in the evolutiony story of our human mind. But these processes are still present in our minds at an unconscious level and participate to many of our human mental states and behaviors. Such positioning of anxiety management as part of the nature of human mind is new and makes available entry points for new understandings of human emotion, motivations and mental disorders. The proposed evolutionary scenario has been introduced in philosophy of mind [Menant 2011, 2014a, b] but it has not been so far explicitly part of primatology nor of psychology/psychiatry/ethics. We present here a drawing of the scenario with highlights on corresponding key points. More work is needed on these new evolutionary links between human mind and anxiety management.

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)

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)

The notion of representation is at the foundation of cognitive sciences and is used in theories of mind and consciousness. Other notions like ‘embodiment’, 'intentionality‘, 'guidance theory' or ‘biosemantics’ have been associated to the notion of representation to introduce its functional aspect. We would like to propose here that a conception of 'usage related' representation eases its positioning in an evolutionary context, and opens new areas of investigation toward self-representation and self-consciousness. The subject is presented in five parts:Following an overall (...) presentation, the first part introduces a usage related representation as being an information managed by a system submitted to a constraint that has to be satisfied. We consider that such a system can generate a meaningful information by comparing its constraint to a received information (Menant 2003). We define a representation as being made of the received information and of the meaningful information. Such approach allows groundings in and out for the representation relatively to the system. The second part introduces the two types of representations we want to focus on for living organisms: representations of conspecifics and auto-representation, the latter being defined without using a notion of self-representation. Both types of representations have existed for our pre-human ancestors which can be compared to today great apes.In the third part, we use the performance of intersubjectivity as identified in group life with the presence of mirror neurons in the organisms. Mirror neurons have been discovered in the 90‘s (Rizzolatti & al.1996, Gallese & al.1996). The level of intersubjectivity that can be attributed to non human primates as related to mirror neurons is currently a subject of debate (Decety 2003). We consider that a limited intersubjectivity between pre-human primates made possible a merger of both types of representations. The fourth part proposes that such a merger of representations feeds the auto-representation with the meanings associated to the representations of conspecifics, namely the meanings associated to an entity perceived as existing in the environment. We propose that auto-representation carrying these new meanings makes up the first elements of self-representation. Intersubjectivity has allowed auto-representation to evolve into self-representation, avoiding the homunculus risk. The fifth part is a continuation to other presentations (Menant 2004, 2005) about possible evolution of self-representation into self-consciousness. We propose that identification with suffering or endangered conspecifics has increased anxiety, and that the tools used to limit this anxiety (development of empathy, imitation, language and group life) have provided a positive feedback on intersubjectivity and created an evolutionary engine for the organism. Other outcomes have also been possible. Such approach roots consciousness in emotions. The evolutionary scenario proposed here does not introduce explicitly the question of phenomenal consciousness (Block 1995). This question is to be addressed later with the help of this scenario.The conclusion lists the points introduced here with their possible continuations. (shrink)
