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.

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.

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.

In this paper, we use the Meaning Generator System (MGS) presented at Gathering in Biosemiotics 2 [1] to analyse the evolution of meaningful information generation through different steps of the evolution of life. Taking as a starting point the usage of MGS for vital constraint satisfaction in basic life (paramecium), we develop its application for more complex living elements up to the case of non-human primate. The thread we follow is relative to the identification of new constraints that can appear through evolution of life, and correspondingly participate to generation of new types of meaningful information. We show that beside the complexification of vital constraints to be satisfied, and in addition to the corresponding enrichment of their satisfaction processes, there is a step in evolution that naturally introduces some specific new constraint in living elements. This step is the one corresponding to the performance of self-representation. Self-representation appeared in evolution at the level of non-human primates. We present the content of self-representation and show that it has a direct consequence on the living element in terms of a new type of constraint to be satisfied. We show that this new constraint participates to the generation of a new set of meaningful information via the MGS, and that the satisfaction of the constraint introduces some natural formulation of emotion generation during the evolution of life. [1]

The presentation proposes to complement an existing development on meaning generation for animals, humans and artificial agents by looking at what could have existed at pre-biotic times and what could be a post-human meaning generation. The core of the approach is based on an existing model for meaning generation: the Meaning Generator System (MGS). The MGS is part of an agent submitted to an internal constraint. The MGS generates a meaning when it receives information that has a connection with the constraint. The generated meaning is used by the agent to implement an action (physical, biological or mental) aimed at satisfying the constraint. The action can be in or out the agent. The purpose of the presentation is to widen the MGS approach in order to reach a coverage for information, constraint and meaning from a pre-biotic level to a possible post-human one. We present the MGS for animals, humans and artificial agents with the corresponding constraints. We then look at what could have been a constraint at a pre-biotic far from thermodynamic equilibrium level. At the other end of the spectrum we look at a possible post-human status with an evolution of a ‘limit anxiety’ human constraint and also with AAs submitted to animal or human type constraints. Such approach links information science with physics, evolution, anthropology, semiotics and human mind. Continuations are proposed.

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.
