The notion of intersubjectivity has achieved a primary status in contemporary psychoanalytic debate, stimulating new theoretical proposals as well as controversies. This paper presents an overview of the main contributions on inter-subjectivity in the field of neurosciences. In humans as well as—probably—in other species, the ability for emotional resonance is guaranteed early in development. Based on this capacity, a primary sense of connectedness is established that can be defined inter-subjective in that it entails sharing affective states and intentions with caregivers. (...) We propose to define such a form of inter-subjectivity ascontingent, since the infant’s early abilities for resonance do not imply the more generalized capacity to permanently conceive of the relationship outside the realm of current interactions and the infant-caregiver’s mutual correspondence of internal states. This form of connection, hence, results in a self-referential, bodily, and affectively codified, context- and time dependent, like-me experience of interactions. The gradual maturation of brain structures and processes as well as interactive experiences allow proper intersubjectivity exchanges, grounded on new intentional and representational capacities, to evolve. In this more mature form of intersubjectivity, the individual is allowed to conceive of her own psychic space both as distinct and as possibly connected with the other’s contents and experience, even in the absence of current behavioral indicators of such correspondence. This multi-layered model of intersubjectivity, which is embraced by current neuroscience research, seems to allow for new interpretations of psychoanalytic models of human relatedness based upon classic clinical observations.

What distinguishes conscious information processing from other kinds of information processing is its phenomenal aspect (PAC), the-what-it-is-like for an agent to experience something. The PAC supplies the agent with a sense of self, and informs the agent on how its self is affected by the agent’s own operations. The PAC originates from the activity that attention performs to detect the state of what I define “the self” (S). S is centered and develops on a hierarchy of innate and acquired values, (...) and is primarily expressed via the central and peripheral nervous systems; it maps the agent’s body and cognitive capacities, and its interactions with the environment. The detection of the state of S by attention modulates the energy level of the organ of attention (OA), i.e., the neural substrate that underpins attention. This modulation generates the PAC. The PAC can be qualified according to five dimensions: qualitative, quantitative, hedonic, temporal and spatial. Each dimension can be traced back to a specific feature of the modulation of the energy level of the OA. (shrink)

This essay builds upon Rebecca Kukla's constructive treatment of Dennettian stances as embodied coping strategies, to extend a conversation previously initiated by John Haugeland about Daniel Dennett on stances and real patterns and Martin Heidegger on the ontological difference. This comparison is mutually illuminating. It advances three underdeveloped issues in Heidegger: Dasein's ‘bodily nature’, the import of Heidegger's ontological pluralism for object identity, and how clarification of the sense of being in general bears on the manifold senses of being. It (...) more sharply differentiates Kukla's and Dennett's understandings of stances and the real. Finally, it allows for further development of Kukla's account of Dennettian stances as embodied. These developments show greater complexity than what Kukla calls ‘the wide and counterfactually flexible repertoire of bodily positions’ that make up an embodied stance. They also show how different stances are compared and assessed even though Kukla rightly denies the possibility of a normative or explanatory philosophical ‘meta-stance’. (shrink)

The aim of this article is to construct an analogy between the synaptic gap and mediated experience. In the brain sciences, the synaptic gap is defined as the space between neurons, a divide across which the activity of the brain is conducted. Research findings suggest that the network of synaptic gaps in the brain best describes the locus of the mind. Mediated experience denotes a perceptual experience made possible by technology, in which a phenomenon is perceived through a representation that (...) has been transmitted as information across a network. The transmission of representational information across a divide is the crux of the analogy between mediated experience and the synaptic gap. Cybernetics, media theory, information theory and postmodern theory have all explored various inferences that follow from the structural resemblance between neural networks and communications media networks. In the arts, theorists have described a networked global brain and posited the emergence of a collective consciousness. In general, these theories are not widely accepted. This article concludes that these theories might be reframed in the light of a recent distinction provided by cognitive science between consciousness and mind. While it is unlikely that networked mediated experience gives rise to a collective consciousness, it may well constitute aspects of an externalization of a collective mind. (shrink)

In recent decades, the scientific study of consciousness has significantly increased our understanding of this elusive phenomenon. Yet, despite critical development in our understanding of the functional side of consciousness, we still lack a fundamental theory regarding its phenomenal aspect. There is an “explanatory gap” between our scientific knowledge of functional consciousness and its “subjective,” phenomenal aspects, referred to as the “hard problem” of consciousness. The phenomenal aspect of consciousness is the first-person answer to “what it’s like” question, and it (...) has thus far proved recalcitrant to direct scientific investigation. Naturalistic dualists argue that it is composed of a primitive, private, non-reductive element of reality that is independent from the functional and physical aspects of consciousness. Illusionists, on the other hand, argue that it is merely a cognitive illusion, and that all that exists are ultimately physical, non-phenomenal properties. We contend that both the dualist and illusionist positions are flawed because they tacitly assume consciousness to be an absolute property that doesn’t depend on the observer. We develop a conceptual and a mathematical argument for a relativistic theory of consciousness in which a system either has or doesn’t have phenomenal consciousness with respect to some observer. Phenomenal consciousness is neither private nor delusional, just relativistic. In the frame of reference of the cognitive system, it will be observable and in other frame of reference it will not. These two cognitive frames of reference are both correct, just as in the case of an observer that claims to be at rest while another will claim that the observer has constant velocity. Given that consciousness is a relativistic phenomenon, neither observer position can be privileged, as they both describe the same underlying reality. Based on relativistic phenomena in physics we developed a mathematical formalization for consciousness which bridges the explanatory gap and dissolves the hard problem. Given that the first-person cognitive frame of reference also offers legitimate observations on consciousness, we conclude by arguing that philosophers can usefully contribute to the science of consciousness by collaborating with neuroscientists to explore the neural basis of phenomenal structures.
