Mirror neurons are widely regarded as an important key to social cognition. Despite such wide agreement, there is very little consensus on how or why they are important. The goal of this paper is to clearly explicate the exact role mirror neurons play in social cognition. I aim to answer two questions about the relationship between mirroring and social cognition: What kind of social understanding is involved with mirroring? How is mirroring related to that understanding? I (...) argue that philosophical and empirical considerations lead us to accord a fairly minimal role for mirror neurons in social cognition. (shrink)

The paper explores the possibilities and limits of naturalizing the experience of intersubjectivity. The existence of mirror neurons illustrates that an experience of intersubjectivity is already present on a more primitive, precognitive, and embodied level. A similar argument had been made in the first half of the twentieth century by phenomenologists, such as Edmund Husserl. This motivated Vittorio Gallese, one of the discoverers of mirror neurons, and other philosophers to connect the functioning of mirror (...) class='Hi'>neurons with Husserl’s phenomenology of intersubjectivity as presented in his Cartesianische Meditationen. I argue that such attempts are grounded in an inadequate interpretation of Husserl’s analysis and turn into a circular argument. As such, they bypass a more primordial experience of intersubjectivity, which Husserl thematizes in Ideen II as the experience of an “expressive unity,” and which resists any project of naturalization from within.

The discovery of mirror neurons in both primates and humans has led to an enormous amount of research and speculation as to how conscious beings are able to interact so effortlessly among one another. Mirror neurons might provide an embodied basis for passive synthesis and the eventual process of further communalization through empathy, as envisioned by Edmund Husserl. I consider the possibility of a phenomenological and scientific investigation of laughter as a point of connection that might (...) in the future bridge the gap Husserl feared had grown too expansive between the worlds of science and philosophy. Part I will describe some implications of the discovery of mirror neurons. Part II will address Husserl’s concept of embodiment as it relates to neuroscience and empathy. Part III will be a primer to investigating laughter phenomenologically. Part IV will be a continuation of the study of laughter and empathy as possible elements helpful in broadening the scope of what Husserl calls the Life-World. (shrink)

Mirror neuron research has come a long way since the early 1990s, and many theorists are now stressing the heterogeneity and complexity of the sensorimotor properties of fronto-parietal circuits. However, core aspects of the initial ‘ mirror mechanism ’ theory, i.e. the idea of a symmetric encapsulated mirroring function translating sensory action perceptions into motor formats, still appears to be shaping much of the debate. This article challenges the empirical plausibility of the sensorimotor segregation implicit in the original (...) mirror metaphor. It is proposed instead that the teleological organization found in the broader fronto-parietal circuits might be inherently sensorimotor. Thus the idea of an independent ‘purely perceptual’ goal understanding process is questioned. Further, it is hypothesized that the often asymmetric, heterogeneous and contextually modulated mirror and canonical neurons support a function of multisensory mapping and tracking of the perceiving agents affordance space. Such a shift in the interpretative framework offers a different theoretical handle on how sensorimotor processes might ground various aspects of intentional action choice and social cognition. Mirror neurons would under the proposed “social affordance model” be seen as dynamic parts of larger circuits, which support tracking of currently shared and competing action possibilities. These circuits support action selection processes—but also our understanding of the options and action potentials that we and perhaps others have in the affordance space. In terms of social cognition ‘ mirror ’ circuits might thus help us understand not only the intentional actions others are actually performing—but also what they could have done, did not do and might do shortly.

Mindreading is the ability to attribute mental states to other individuals. According to the simulation theory (ST), mindreading is based on the ability the mind has of replicating others' mental states and processes. Mirror neurons (MNs) are a class of neurons that fire both when an agent performs a goal-directed action and when she observes the same type of action performed by another individual. Since MNs appear to form a replicative mechanism in which a portion of the (...) observer's brain replicates the agent's brain, MNs have been considered evidence in favor of ST. Jacob (2008), however, has maintained that the recent discovery of so-called logically related MNs refutes the hypothesis that MNs form a replicative mechanism. In this paper, I argue that, contrary to what is claimed by Jacob, one can accept the existence of logically related MNs and, at the same time, still maintain that the activity of MNs is replicative. It follows that MNs still support ST. (shrink)

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

Primatologists generally agree that monkeys lack higher-order intentional capacities related to theory of mind. Yet the discovery of the so-called "mirror neurons" in monkeys suggests to many neuroscientists that they have the rudiments of intentional understanding. Given a standard philosophical view about intentional understanding, which requires higher-order intentionahty, a paradox arises. Different ways of resolving the paradox are assessed, using evidence from neural, cognitive, and behavioral studies of humans and monkeys. A decisive resolution to the paradox requires substantial (...) additional empirical work and perhaps a rejection of the standard philosophical view. (shrink)

The discovery of so-called ‘mirror neurons’ - found to respond both to own actions and the observation of similar actions performed by others - has been enormously influential in the cognitive sciences and beyond. Given the self-other symmetry these neurons have been hypothesized as underlying a ‘mirror mechanism’ that lets us share representations and thereby ground core social cognitive functions from intention understanding to linguistic abilities and empathy. I argue that mirror neurons are important (...) for very different reasons. Rather than a symmetric ubiquitous or context- independent mechanism, I propose that these neurons are part of broader sensorimotor circuits, which help us navigate and predict the social affordance space that we meet others in. To develop both the critical and positive project I analyze the interpretive choices and the debate surrounding the mirror neuron research and show how the field is marred by highly questionable assumptions about respectively motor and social cognition. The discovery of mirror neurons - and the sensorimotor circuits of which these neurons are a part – actually empirically challenge many of these tacit assumptions. Findings of sensorimotor goal representations at levels of abstraction well beyond actual sensory information and kinetic movements challenge the idea of motor cognition as primarily output production. Additionally, the focus on 3rd person mindreading of hidden mental states is misguiding the field of social cognition. Much ‘mind-reading’ seems rooted in sensorimotor representations and a developmentally primary 2nd person understanding of actions and the mental lives of others, which precisely breaks the assumed dichotomy between mind and behavior. I propose a Social Affordance model where parallel fronto-parietal sensorimotor circuits support representations not just of other people’s actions but of the overall social affordance space. It is a process that monitors concrete goals and teleological possibilities that the environment affords respectively oneself and other present agents. With this model I hypothesize that the complex spectrum of sensorimotor integrations are indeed essential not only to normal action choice calibration but also to social cognitive abilities, as the sensorimotor teleological representations let us relate to others and understand their action choices in a shared pragmatic and intentional context.

We focus on the thesis that action understanding is a function of the mirror neuron system. According to our opinion, understanding is a process that runs through hermeneutic circles from the “Vorverständnis” (“previous understanding”) to steps of deeper understanding. Our critique relates to the narrow neuroscientific definition of action understanding as the capacity to recognize several movements as belonging to one action. After a reconstruction of the model's developments, we will challenge the claims of the model by Rizzolatti and (...) Sinigaglia (2010). By analyzing the relation between the experimental results and its interpretation, we will conclude that there is no proof that mirror neuron activity leads to action understanding. (shrink)

Largely aided by the neurological discovery of so-called “ mirror neurons,” the attention to motor activity during action observation has exploded over the last two decades. The idea that we internally “ mirror ” the actions of others has led to a new strand of implicit simulation theories of action understanding[1][2]. The basic idea of this sort of simulation theory is that we, via an automatic covert activation of our own action representations, can understand the action and (...) possibly the goal and/or intentions of the observed agent. In this way motor “simulation” is seen as the basis for low-level “mind-reading”; i.e. for the ascription of goals and intentional mental states to others. The thought is that one, through mirroring simulations, can get beyond the observable behaviour to the hidden minds of others. I am questioning the idea of an exclusively “mirroring” role of the motor system in social perception, which is tacitly assumed in this sort of simulation theories. Is motor activity during action observation really primarily a simulation, a detailed “echo” of the others action? My point is not that we never simulate what we observe, but rather to question whether such processes are representative of the overall motor contribution to social cognition. More and more studies on the functional properties of mirror neurons and motor facilitation during perception points to a more complex role of the motor system in action perception. Recently, several proposals have been made attempting to reinterpret and critique the function of motor activity in social situations. I shall here briefly touch on a few of these and sketch parts of my own alternative “social affordance” hypothesis of the sensorimotor contribution to social perception. By way of these analyses I highlight how traditional discussions are marred by problematic theoretical assumptions. It seems to me that we need a thorough reinterpretation not just of mirror neurons and mirroring, but also of what we take motor and social cognition to be. In my view the details of the sensorimotor findings underline the need to move beyond the simplistic idea of the motor system as a unitary output system. In terms of social cognition I question the traditional focus on hidden mental states. I suggest that the motor contribution might have more to do with understanding the process of how others choose their actions, navigate the world and relate to others than with simulating specific actual actions or mental states. I conclude that low-level simulation theories, which see the motor role in social perception as passive “mirroring,” are faced with serious empirical challenges, and that the motor system serve a much more proactive and complex cognitive role in social perception and interaction than previously thought. But my claim is also that many empirical tensions have slipped out of focus due to entrenched theoretical assumptions. Narrow theoretical expectations have marked not only the interpretations but the research itself and I propose that we are in dire need of more studies of actual contextual and interactive social perception.

A crucial socio-political challenge for our age is how to rede!ne or extend group membership in such a way that it adequately responds to phenomena related to globalization like the prevalence of migration, the transformation of family and social networks, and changes in the position of the nation state. Two centuries ago Immanuel Kant assumed that international connectedness between humans would inevitably lead to the realization of world citizen rights. Nonetheless, globalization does not just foster cosmopolitanism but simultaneously yields the (...) development of new group boundaries. Group membership is indeed a fundamental issue in political processes, for: “the primary good that we distribute to one another is membership in some human community” – it is within the political community that power is being shared and, if possible, held back from non-members. In sum, it is appropriate to consider group membership a fundamental ingredient of politics and political theory. How group boundaries are drawn is then of only secondary importance. Indeed, Schmitt famously declared that “[e]very religious, moral, economic, ethical, or other antithesis transforms into a political one if it is suffciently strong to group human beings e#ectively according to friend and enemy”. Even though Schmitt’s idea of politics as being constituted by such antithetical groupings is debatable, it is plausible to consider politics among other things as a way of handling intergroup di#erences. Obviously, some of the group-constituting factors are more easily discernable from one’s appearance than others, like race, ethnicity, or gender. As a result, factors like skin color or sexual orientation sometimes carry much political weight even though individuals would rather con!ne these to their private lives and individual identity. Given the potential tension between the political reality of particular groupmembership defnitions and the – individual and political – struggles against those definitions and corresponding attitudes, citizenship and civic behavior becomes a complex issue. As Kymlicka points out, it implies for citizens an additional obligation to non-discrimination regarding those groups: “[t]his extension of non-discrimination from government to civil society is not just a shift in the scale of liberal norms, it also involves a radical extension in the obligations of liberal citizenship”. Unfortunately, empirical research suggests that political intolerance towards other groups “may be the more natural and ‘easy’ position to hold”. Indeed, since development of a virtue of civility or decency regarding other groups is not easy, as it often runs against deeply engrained stereotypes and prejudices, political care for matters like education is justified. Separate schools, for example, may erode children’s motivation to act as citizens, erode their capacity for it and!nally diminish their opportunities to experience transcending their particular group membership and behave as decent citizens. This chapter outlines a possible explanation for such consequences. That explanation will be found to be interdisciplinary in nature, combining insights from political theory and cognitive neuroscience. In doing so, it does not focus on collective action, even though that is a usual focus for political studies. For example, results pertaining to collective political action have demonstrated that the relation between attitudes and overt voting behavior or political participation is not as direct and strong as was hoped for. Several conditions, including the individual’s experiences, self-interest, and relevant social norms, turned out to interfere in the link between his or her attitude and behavior. Important as collective action is, this chapter is concerned with direct interaction between agents and the in$uence of group membership on such interaction – in particular joint action. Although politics does include many forms of action that require no such physical interaction, such physical interaction between individuals remains fundamental to politics – this is the reason why separate schooling may eventually undermine the citizenship of its isolated pupils. This chapter will focus on joint action, de!ned as: “any form of social interaction whereby two or more individuals coordinate their actions in space and time to bring about a change in the environment”. Cognitive neuroscienti!c evidence demonstrates that for such joint action to succeed, the agents have to integrate the actions and expected actions of the other person in their own action plans at several levels of speci!city. Although neuroscienti!c research is necessarily limited to simple forms of action, this concurs with a philosophical analysis of joint action, which I will discuss below. (shrink)

There is much disagreement about how extensive a role theoretical mind-reading, behavior-reading, and simulation each have and need to have in our knowing and understanding other minds, and how each method is implemented in the brain, but less discussion of the epistemological question what it is about the products of these methods that makes them count as knowledge or understanding. This question has become especially salient recently as some have the intuition that mirror neurons can bring understanding of (...) another's action despite involving no higher-order processing, whereas most epistemologists writing about understanding think that it requires reflective access to one's grounds, which is closer to the intuitions of other commenters on mirror neurons. I offer a definition of what it is that makes something understanding that is compelling independently of the context of cognition of other minds, and use it to show two things: 1) that theoretical mind-reading and simulation bring understanding in virtue of the same epistemic feature, and 2) why the kind of motor representation without propositional attitudes that is done by mirror neurons is sufficient for action understanding. I further suggest that more attention should be paid to the potential disadvantages of a simulative method of knowing. Though it can be more efficient in some cases, it can also bring vulnerability, wear and tear on one's personal equipment, and unintended mimicry. (shrink)

In recent years, some simulation theorists have claimed that the discovery of mirror neurons provides empirical support for the position that mind reading is, at some basic level, simulation. The purpose of this essay is to question that claim. I begin by providing brief context for the current mind reading debate and then developing an influential simulationist account of mind reading. I then draw on the works of Edmund Husserl and Edith Stein to develop an alternative, phenomenological account. (...) In conclusion, I offer multiple objections against simulation theory and argue that the empirical evidence mirror neurons offer us does not necessarily support the view that empathy is simulation.

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)

In this paper, an account of theoretical integration in cognitive (neuro)science from the mechanistic perspective is defended. It is argued that mechanistic patterns of integration can be better understood in terms of constraints on representations of mechanisms, not just on the space of possible mechanisms, as previous accounts of integration had it. This way, integration can be analyzed in more detail with the help of constraintsatisfaction account of coherence between scientific representations. In particular, the account has resources to talk of (...) idealizations and research heuristics employed by researchers to combine separate results and theoretical frameworks. The account is subsequently applied to an example of successful integration in the research on hippocampus and memory, and to a failure of integration in the research on mirror neurons as purportedly explanatory of sexual orientation.

This contribution proposes how beholders may internally process unfinished works of art. It does so by considering five of Michelangelo Buonarroti’s interrupted sculptures and pointing out their empathic and imaginative potential. The beholder focused on the surface, I propose, is inclined to mentally simulate the artist’s gesture that drafted the sculptures through the visible graphic signs of the chisels. This inner simulation takes place within the activation of various brain networks, located in the brain’s motor system. Renaissance authors associated the (...) observation of the unfinished to learning and, as this article shows, this assumption seems to find confirmation in recent neuroscientific studies on mirror neurons and imitation learning. In this way, the empathic engagement established between the beholder and the work of art observed – as well as the role played by embodied simulation and imagination in this kind of visual perception – clarifies how the incompleteness can also have that pedagogical function recognised by Giorgio Vasari and Benvenuto Cellini.

Joint actions often require agents to track others’ actions while planning and executing physically incongruent actions of their own. Previous research has indicated that this can lead to visuomotor interference effects when it occurs outside of joint action. How is this avoided or overcome in joint actions? We hypothesized that when joint action partners represent their actions as interrelated components of a plan to bring about a joint action goal, each partner’s movements need not be represented in relation to distinct, (...) incongruent proximal goals. Instead they can be represented in relation to a single proximal goal – especially if the movements are, or appear to be, mechanically linked to a more distal joint action goal. To test this, we implemented a paradigm in which participants produced finger movements that were either congruent or incongruent with those of a virtual partner, and either with or without a joint action goal (the joint flipping of a switch, which turned on two light bulbs). Our findings provide partial support for the hypothesis that visuomotor interference effects can be reduced when two physically incongruent actions are represented as mechanically interdependent contributions to a joint action goal.

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)

I argue that when we use email, text messaging, or social media websites such as Facebook to interact, rather than communicating face-to-face, we do not experience the best kind of empathy, which is most conducive to experiencing benevolence for others. My arguments rely on drawing interdisciplinary connections between sources: early modern accounts of sympathy, dance theory, philosophy of technology, and neuroscience/psychology. I reflect on theories from these disciplines which, taken together, suggest that to empathize optimally, we must see or hear (...) each other’s bodily gestures, vocal intonations, and facial expressions.

Mindreading is the ability to attribute mental states to other individuals. According to the Theory-Theory (TT), mindreading is based on one's possession of a Theory of Mind. On the other hand, the Simulation Theory (ST) maintains that one arrives at the attribution of a mental state by simulating it in one's own mind. In this paper, I propose a ST-TT hybrid model of the ability to attribute disgust on the basis of visual stimuli such as facial expressions, body postures, etc. (...) More precisely, while I defend Goldman's (2006) thesis that the ability to attribute disgust based on observing disgusted facial expressions stems from a mirror-based simulation process, I argue that ST is unable to account for the ability to attribute disgust based on non-facial visual stimuli; I propose, rather, that this latter ability is theory-based. My model is grounded in evidence from individuals suffering from Huntington's Disease. (shrink)

David Hume endorses three claims that are difficult to reconcile: (1) sympathy with those in distress is sufficient to produce compassion towards their plight, (2) adopting the general point of view often requires us to sympathize with the pain and suffering of distant strangers, but (3) our care and concern is limited to those in our close circle. Hume manages to resolve this tension, however, by distinguishing two types of sympathy. We feel compassion towards those around us because associative sympathy (...) causes us to mirror their pain and suffering, but our ability to enter into the afflictions of those remote from us involves cognitive sympathy and merely requires us to reflect upon how we would feel in their shoes. This hybrid theory of sympathy receives support from recent work on affective mirroring and cognitive pretense. Hume’s account should appeal to contemporary researchers, therefore, who are interested in the nature of moral imagination. (shrink)

I recommend this balanced, tripartite examination of phenomenology, psychology, and neuroscience.

the article presents Jean Paul Sartre’s idea of the human body and the bodiliness described in his book Being and nothingness (1943). In this book, Sartre argued that every human relation is based on the objecti cation of one human by another, and entering into empathic contact is basically impossible. the author of the article has con onted this thesis with contemporary psychological and neuropsychological thought (mirror neuron theory) and has investigated how the category of empathy functions in literary (...) studies. A very important part of this article is the re ection on the presence and topicality of Sartre’s beliefs in the literature. the author has conducted an interpretation of Witold gombrowicz’s story Tancerz mecenasa Kraykow‐ s ego (1926) om the collection Bakakaj (1957), and has shown that the ideas presented by Sartre are re ected there in a very interesting way. Sartre’s philosophy turns out to be abso‐ lutely up‐to‐date right now, more than many psychological theories — it not only supplies a philosophical base for the analysis of human relations (those also presented in literature), but also gives a certain tool for describing them in the form of speci c language and terminology.

The purpose of this essay is to advocate the ideas of Wilhelm Worringer, John Dewey, and Nelson Goodman on the roles of perception, empathy, emotion, and enjoyment in aesthetic experience. I will attempt to do this by offering a novel interpretation of some of these thinkers’ insights from a biological perspective. To this end, I will consider the following questions. What is an aesthetic experience? Does such a thing exist at all? If yes, is there a correlation between the concept (...) of the aesthetic and perception? Is it possible, then, to find a biological basis for aesthetic experience? My argument is that a fresh analysis of the aesthetics of Worringer, Dewey, and Goodman, in light of some of the discoveries and theories of the cognitive neurosciences – such as the biological correlations of emotions, the “as-if-body-loop” theory, the discovery of mirror neurons, and the phenomenon of embodied simulation – may provide a contribution to longstanding philosophical problems relating to the nature of aesthetic experience.

Recent research on infant and animal imitation and on mirror neuron systems has brought imitation back in focus in psychology and cognitive science. This topic has always been important for philosophical hermeneutics as well, focusing on theory and method of understanding. Unfortunately, relations between the scientific and the hermeneutic approaches to imitation and understanding have scarcely been investigated, to the loss of both disciplines. In contrast to the cognitive scientific emphasis on sharing and convergence of representations, the hermeneutic analysis (...) emphasizes the indeterminacy and openness of action understanding due to preunderstanding, action configuration, and the processual nature of understanding. This article discusses empirical evidence in support of these aspects and concludes that hermeneutics can contribute to the scientific investigation of imitation and understanding. Since, conversely, some grounding—and constraining—aspects of hermeneutics may be derived from cognitive science, both should be integrated in a multilevel explanation of imitation and understanding. This holds also for explanations that are largely based on mirror neuron systems, since these appear to be sensitive to developmental and experiential factors, too. (shrink)

This paper will examine poetry and rhythm in relation to biological and evolutionary models in order to develop a hypothetical methodology by which certain aspects of literature may be examined through an evolutionary lens. It is by no means an attempt at a finalizing or totalizing way of examining literature, but as such attempts have largely been ignored or assaulted, there is a rather large niche to fill. Hence this article will attempt to redefine literature as a ‘Third Level Darwin (...) Machine’ and parallel the science/culture/Theory debate with that in physics/string theory and then it will connect poetry to Boyd’s idea of ‘rhythm and attention’ along with 'motor resonance', mirror neurons and music theory. It will then look at the influence of Emily Dickinson’s rhythmic and metaphoric compression on the poetry of Hart Crane as a mimetic function following Boyd’s notion of attention, pattern and play as functions of a Third Level Darwinian Machine which will be the operative foundation for a naturalized (but not totalized) account of poetic effect and its relation to the human species’ evolved history.

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)

Successful athletic performance requires precision in many respects. A batter stands behind home plate awaiting the arrival of a ball that is less than three inches in diameter and moving close to 100 mph. His goal is to hit it with a ba­­t that is also less than three inches in diameter. This impressive feat requires extraordinary temporal and spatial coordination. The sweet spot of the bat must be at the same place, at the same time, as the ball. A (...) basketball player must keep a ball bouncing as she speeds from one end of the court to another, evading defensive players. She may never break pace as she lifts from the ground, throwing the ball fifteen feet toward a hoop that is eighteen inches in diameter. One task facing a psychologist involves explaining how the body does such things within the sometimes very demanding spatial and temporal constraints that a given task imposes. Part of the goal of this chapter is to sketch the commitments of an embodied approach to such an explanation. We shall see that an embodied account of motor skills draws concepts that depart radically from more traditional cognitivist theories of motor activity. Similarly, because an embodied approach to cognition introduces new ways to understand the human capacity for social interaction, it also promises to shed new light on how athletes coordinate their actions with each other.

This paper will attempt a methodological configuration to link the natural sciences (evolutionary theory & neurology) to literature (lullabies and poetry, specifically). It uses findings in neuroscience and animal neurology as well as the theories of evolution by natural selection in to examine patterns in lullabies, and then connect these to poetry. As one will never find a ‘metaphor gene’, nor do genes even code for behaviors –coding instead for traits- is it possible to even locate overlaps between the disciplines (...) of natural science and literature? Doing so requires a mixed methods approach. This article seeks to build on the existing philosophical and theoretical ground of current natural science in order to establish a dialogue with current cultural and literary theories. (shrink)

The article is an experiment that deals with "Embodied Simulation" and " Embodied Cognition". This work follows the procedures of studies of the Parma Group and against them try to demonstrate their failure. The cognition is not embodied at all, maybe a little and at least.

La question des rapports du spinozisme à l’axiologie a fait l’objet de nombreux débats. Certains commentateurs considèrent Spinoza comme étant profondément immoraliste, alors que pour d’autres, il maintient l'ensemble des valeurs humaines. Spinoza a cherché à dépasser l’utilitarisme propre au conatus de chacun, afin de fonder un altruisme rationnel. Il souligne que le bien auquel l’homme aspire lorsqu’il suit la vertu, il le désirera aussi pour tous les autres hommes. Cependant, les moyens mis en œuvre pour démontrer cette thèse semblent (...) problématiques. Cet article analyse la logique de la coopération interhumaine élaborée par Spinoza, ainsi que son idéal de l’homme libre, montrant, qu'en fait, il n'a pas réussi à surmonter la nature profondément égoïste du conatus. -/- The question of the relationship between Spinozism and axiology has been the subject of much debate. Some commentators consider Spinoza to be profoundly immoralist, while for others he upholds the set of human values. Spinoza sought to go beyond the utilitarianism proper to the conatus of each person, in order to establish a rational altruism. He emphasizes that the good to which man aspires when he follows virtue, he will also desire for all other men. However, the means used to demonstrate this thesis seem problematic. This article analyzes Spinoza's logic of interhuman cooperation, as well as his ideal of the free man, showing that, in fact, he failed to overcome the profoundly egoistic nature of conatus. -/- .

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.

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)

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.

Interpreting others' actions is essential for understanding the intentions and goals in social interactions. Activity in the motor cortex is evoked when we see another person performing actions, which can also be influenced by the intentions and context of the observed action. No study has directly explored the influence of reward and punishment on motor cortex activity when observing others' actions, which is likely to have substantial relevance in different social contexts. In this experiment, EEG was recorded while participants watched (...) movie clips of a person performing actions that led to a monetary reward, loss or no change for the observer. Using the EEG mu rhythm as an index of motor resonance, our results demonstrate that observation of rewarding actions produce significantly greater motor cortex activity than punishing or neutral actions, with punishing actions producing greater activity than neutral ones. In addition, the dynamic change in the mu rhythm over sensorimotor cortex is modulated by reward and punishment, with punishing actions producing a prolonged suppression. These findings demonstrate that the associated reward value of an observed action may be crucial in determining the strength of the representation of the action in the observer's brain. Consequently, reward and punishment is likely to drive observational learning through changes in the action observation network, and may also influence how we interpret, understand, engage in and empathize with others' actions in social interaction.

Purpose – For half a century, neuroscientists have used Shannon Information Theory to calculate “information transmitted,” a hypothetical measure of how well neurons “discriminate” amongst stimuli. Neuroscientists’ computations, however, fail to meet even the technical requirements for credibility. Ultimately, the reasons must be conceptual. That conclusion is confirmed here, with crucial implications for neuroscience. The paper aims to discuss these issues. Design/methodology/approach – Shannon Information Theory depends upon a physical model, Shannon’s “general communication system.” Neuroscientists’ interpretation of that model (...) is scrutinized here. Findings – In Shannon’s system, a recipient receives a message composed of symbols. The symbols received, the symbols sent, and their hypothetical occurrence probabilities altogether allow calculation of “information transmitted.” Significantly, Shannon’s system’s “reception” (decoding) side physically mirrors its “transmission” (encoding) side. However, neurons lack the “reception” side; neuroscientists nonetheless insisted that decoding must happen. They turned to Homunculus, an internal humanoid who infers stimuli from neuronal firing. However, Homunculus must contain a Homunculus, and so on ad infinitum – unless it is super-human. But any need for Homunculi, as in “theories of consciousness,” is obviated if consciousness proves to be “emergent.” Research limitations/implications – Neuroscientists’ “information transmitted” indicates, at best, how well neuroscientists themselves can use neuronal firing to discriminate amongst the stimuli given to the research animal. Originality/value – A long-overdue examination unmasks a hidden element in neuroscientists’ use of Shannon Information Theory, namely, Homunculus. Almost 50 years’ worth of computations are recognized as irrelevant, mandating fresh approaches to understanding “discriminability.”. (shrink)

We humans have a formidable armamentarium of social display behaviours, including song-and-dance, the visual arts, and role-play. Of these, role-play is probably the crucial adaptation which makes us most different from other apes. Human childhood, a sheltered period of ‘extended irresponsibility’, allows us to develop our powers of make-believe and role-play, prerequisites for human cooperation, culture, and reflective consciousness. Social mirror theory, originating with Dilthey, Baldwin, Cooley and Mead, holds that there cannot be mirrors in the mind without mirrors (...) in society. I will present evidence from the social and behavioural sciences to argue that self-awareness depends on social mirrors and shared experiential worlds. The dependence of reflectivity on shared experience requires some reframing of the ‘hard problem’, and suggests a non-trivial answer to the zombie question. (shrink)

Understanding how biological organisms are autonomous—maintain themselves far from equilibrium through their own activities—requires understanding how they regulate those activities. In multicellular animals, such control can be exercised either via endocrine signaling through the vasculature or via neurons. In C. elegans this control is exercised by a well-delineated relatively small but distributed nervous system that relies on both chemical and electric transmission of signals. This system provides resources to integrate information from multiple sources as needed to maintain the organism. (...) Especially important for the exercise of neural control are neuromodulators, which we present as setting agendas for control through more traditional electrical signaling. To illustrate how the C. elegans nervous system integrates multiple sources of information in controlling activities important for autonomy, we focus on feeding behavior and responses to adverse conditions. We conclude by considering how a distributed nervous system without a centralized controller is nonetheless adequate for autonomy. (shrink)

Santiago Ramón y Cajal practice what became neuroscience in the remote town of Ayerbe, Aragón Spain. He struggled to travel to conferences in northern Europe to share his remarkable discovery.

Recent research suggests that human memories are stored not between neurons as synaptic weights, but within individual neurons themselves. This opens the possibility to replace the dominant paradigm of brain function – neural networks – with a new one. In this article, I explore how “identified neurons” could explain how memories are stored, and how human traits are implemented in the brain.

In his article “Beyond Point-and-Shoot Morality,” Joshua Greene argues that the empirical findings of cognitive neuroscience have implications for ethics. Specifically, he contends that we ought to trust our manual, conscious reasoning system more than our automatic, emotional system when confronting unfamiliar problems; and because cognitive neuroscience has shown that consequentialist judgments are generated by the manual system and deontological judgments are generated by the automatic system, we ought to trust the former more than the latter when facing unfamiliar moral (...) problems. In the present article, I analyze one of the premises of Greene’s argument. In particular, I ask what exactly an unfamiliar problem is and whether moral problems can be classified as unfamiliar. After exploring several different possible interpretations of familiarity and unfamiliarity, I conclude that the concepts are too problematic to be philosophically compelling, and thus should be abandoned.

What do we see in a mirror? There is an ongoing debate whether mirrors present us with images of objects or whether we see, through the mirror, the objects themselves. Roberto Casati has recently argued that there is a categorical difference between images and mirror-reflections. His argument depends on the observation that mirrors, but not paintings, are sensitive to changes in the observer’s prospective. In our paper we scrutinize Casati’s argument and present a modal argument that shows (...) that it cannot establish this conclusion. We suggest that Casati’s line of reasoning suffers from the fact that he does not take dynamic images, i.e., images that change over time, into account. (shrink)

A new strategy for moving forward in the characterization of the Global Neuronal Workspace (GNW) is proposed. According to Dehaene, Changeux and colleagues, broadcasting is the main function of the GNW. However, the dynamic network properties described by recent graph-theoretic GNW models are consistent with many large-scale communication processes that are different from broadcasting. We propose to apply a different graph-theoretic approach, originally developed for optimizing information dissemination in communication networks, which can be used to identify the pattern of frequency (...) and phase-specific directed functional connections that the GNW would exhibit only if it were a broadcasting network.

This paper accomplishes three goals. First, the essay demonstrates that Edmund Husserl’s theory of meaning consciousness from his 1901 Logical Investigations is internally inconsistent and falls apart upon closer inspection. I show that Husserl, in 1901, describes non-intuitive meaning consciousness as a direct parallel or as a ‘mirror’ of intuitive consciousness. He claims that non-intuitive meaning acts, like intuitions, have substance and represent their objects. I reveal that, by defining meaning acts in this way, Husserl cannot account for our (...) experiences of countersensical, absurd, or impossible meanings. Second, I examine how Husserl came to recognize this 1901 mistake in his 1913/14 Revisions to the Sixth Logical Investigation. I discuss how he accordingly reformulates his understanding of non-intuitive meaning acts from the ground up in those Revisions, where this also allows for him to properly account for the experience of impossible meanings. Instead of describing them as mirrors of intuitions, Husserl takes non-intuitive meaning acts to be modifications of intuitions, where they have no substance and do not represent their objects. Finally, in the conclusion to this essay, I demonstrate how this fundamental change to his understanding of meaning consciousness forced Husserl to revise other central tenets of his philosophy, such that the trajectory of his thought can only be properly understood in light of these revisions to his theory of non-intuitive meaning consciousness.

This paper introduces "Moral Mirrorism," a novel theory that intertwines objective truth with emotional attitudes in moral assertions. By critically analyzing moral cognitivism, expressivism, and hybrid theories, as well as naturalistic and non-naturalistic moral realism, the paper seeks to reconcile the conflicting aspects of these perspectives. Moral Mirrorism emphasizes that objective truth and emotional attitudes interactively shape moral assertions, offering a comprehensive framework for understanding moral language. Furthermore, the theory proposes practical applications in policy-making, moral education, and international relations, aiming (...) to enhance consensus-building and moral decision-making. Although cultural diversity and subjectivity present challenges, Moral Mirrorism holds significant potential for further development in moral philosophy. (shrink)

Methodology and theory in science are related to a philosophy in which the centric position of the first person, perception and cognition are made the exclusive focus for interpretation involving mirroring, symbolism, and need, criteria from which major first scientific works in Anthropology originated. A new orientation is found for some notions in physics and cosmology, especially those revolved around an ether as a substrate for the transmission of light that are used in explanation in Theory of Relativity, interpretation of (...) experiment. The interferometer and red shift, theory and experiment in biology, as well as aspects of Ancient Philosophies, and a modern age of extended means of communication are discussed and compared in critique with respect to a visual model, created mathematically, of an egg, that is used to demonstrate proposed physical and conceptual form. The Earth, civilization is argued to have a unaware two-timing complex in thinking social and behavioral aspects caused by the external invasion of spaces by unknown phenomenon dating back to the time of Eve and reflected from a philosophical incompleteness to a space structured with a like two-timed weave of conceptual and material form.

The image of the “mirror” (鏡kagami) appears frequently in the philosophical texts of Nishida Kitaro (西田幾多郎1870-1945), where it assumes various functions. Mirror references first occur in meditations on the philosophies of Josiah Royce (1855-1916) and Henri Bergson (1859-1941). The most fascinating evocation here corresponds to the idea of a “self-enlightening mirror”, used to probe the philosophical ground for self-illumination. This idea seems to point back to Buddhist meaning that intervenes in Japanese intellectual history. We take this as (...) our warrant for establishing here, firstly, how Nishidean philosophical speculation can be critically related to the thought of Dogen (道元1200-1253); and, secondly, in what sense it has stimulated some contemporary approaches in Japanese philosophy (for example, those of Nitta, Ohashi, and Sakabe).

The electric activities of cortical pyramidal neurons are supported by structurally stable, morphologically complex axo-dendritic trees. Anatomical differences between axons and dendrites in regard to their length or caliber reflect the underlying functional specializations, for input or output of neural information, respectively. For a proper assessment of the computational capacity of pyramidal neurons, we have analyzed an extensive dataset of three-dimensional digital reconstructions from the NeuroMorphoOrg database, and quantified basic dendritic or axonal morphometric measures in different regions and (...) layers of the mouse, rat or human cerebral cortex. Physical estimates of the total number and type of ions involved in neuronal electric spiking based on the obtained morphometric data, combined with energetics of neurotransmitter release and signaling fueled by glucose consumed by the active brain, support highly efficient cerebral computation performed at the thermodynamically allowed Landauer limit for implementation of irreversible logical operations. Individual proton tunneling events in voltage-sensing S4 protein alpha-helices of Na+, K+ or Ca2+ ion channels are ideally suited to serve as single Landauer elementary logical operations that are then amplified by selective ionic currents traversing the open channel pores. This miniaturization of computational gating allows the execution of over 1.2 zetta logical operations per second in the human cerebral cortex without combusting the brain by the released heat.
