What is the primary function of consciousness in the nervous system? The answer to this question remains enigmatic, not so much because of a lack of relevant data, but because of the lack of a conceptual framework with which to interpret the data. To this end, we have developed Passive Frame Theory, an internally coherent framework that, from an action-based perspective, synthesizes empirically supported hypotheses from diverse fields of investigation. The theory proposes that the primary function of consciousness is well-circumscribed, (...) serving the 'somatic nervous system[. For this system, consciousness serves as a frame that constrains and directs skeletal muscle output, thereby yielding adaptive behavior. The mechanism by which consciousness achieves this is more counterintuitive, passive, and “low level” than the kinds of functions that theorists have previously attributed to consciousness. Passive frame theory begins to illuminate (a) what consciousness contributes to nervous function, (b) how consciousness achieves this function, and (c) the neuroanatomical substrates of conscious processes. Our untraditional, action-based perspective focuses on olfaction instead of on vision and is 'descriptive' (describing the products of nature as they evolved to be) rather than 'normative' (construing processes in terms of how they should function). Passive frame theory begins to isolate the neuroanatomical, cognitive-mechanistic, and representational (e.g., conscious contents) processes associated with consciousness. (shrink)

In this paper, we suggest that affect meets the traditional definition of “cognition” such that the affect–cognition distinction is phenomenological, rather than ontological. We review how the affect–cognition distinction is not respected in the human brain, and discuss the neural mechanisms by which affect influences sensory processing. As a result of this sensory modulation, affect performs several basic “cognitive” functions. Affect appears to be necessary for normal conscious experience, language fluency, and memory. Finally, we suggest that understanding the differences between (...) affect and cognition will require systematic study of how the phenomenological distinction characterising the two comes about, and why such a distinction is functional.

Argues that truth, moral right, political right, and aesthetic value may be understood as arising out of a naturalist account of humanity, if naturalism is rightly conceived.

There is remarkable variety in emotional life. Not all mental states referred to by the same word (e.g., “fear”) look alike, feel alike, or have the same neurophysiological signature. Variability has been observed within individuals over time, across individuals from the same culture, and of course across cultures. In this paper, I outline an approach to understanding the richness and diversity of emotional life. This model, called the conceptual act model, is not only well suited to explaining individual differences in (...) the frequency and quality of emotion, but it also suggests the counter-intuitive view that the variety in emotional life extends past the boundaries of events that are conventionally called “emotion” to other classes of psychological events that people call by different names, such as “cognitions”. As a result, the conceptual act model is a unifying account of the broad variety of mental states that constitute the human mind. (shrink)

The late Nietzsche defended a position which he sometimes to refers as ‘sensualism’ and which consists of two main theses: senses ‘do not lie’ (T1) and sense organs are ‘causes’ (T2). Two influential interpretations of this position have been proposed by Clark and Hussain, who also address the question whether Nietzsche's late sensualism is (Hussain) or not (Clark) compatible with the epistemological view which he held in his previous work and which has been dubbed the ‘falsification thesis’ (FT). In my (...) paper I will show that both readings raise substantial difficulties and propose an alternative account of Nietzsche's sensualism. In particular, I will argue: (a) that according to Nietzsche the representational content of sensory experience ‘does not lie’ since it is physically grounded in causal exchanges with the external world which are mediated by sense organs; (b) that Nietzsche believes that the claim that senses ‘do not lie’ is also true of the phenomenal, qualitative content of sensory experience; and (c) that FT, despite its prima facie tension with (a) and (b), fit well Nietzsche's sensualism.

This paper proposes a theory of how conscious emotional experience is produced by the brain as the result of many interacting brain areas coordinated in working memory. These brain areas integrate perceptions of bodily states of an organism with cognitive appraisals of its current situation. Emotions are neural processes that represent the overall cognitive and somatic state of the organism. Conscious experience arises when neural representations achieve high activation as part of working memory. This theory explains numerous phenomena concerning emotional (...) consciousness, including differentiation, integration, intensity, valence, and change. Ó 2007 Elsevier Inc. All rights reserved.

The explanatory challenge of sentience is known as the “hard problem of consciousness”: How does subjective experience arise from physical objects and their relations? Despite some optimistic claims, the perennial struggle with this question shows little evidence of imminent resolution. In this article I focus on the “why” rather than on the “how” of sentience. Specifically, why did sentience evolve in organic lifeforms? From an evolutionary perspective this question can be framed: “What adaptive problem(s) did organisms face in their evolutionary (...) past and how were those challenges met? I argue that sentience was a critical component of the adaptive solution (i.e., adopting an agentic stance) to increasingly complex and unpredictable demands placed on vertebrates approximately 500 million years ago (the so-called Cambrian explosion). One consequence of taking an agentic stance is that it freed the organism from its neural moorings, positioning it within phenomenal space outside its brain. (shrink)

We discuss the evolutionary transition from animals with limited experiencing to animals with unlimited experiencing and basic consciousness. This transition was, we suggest, intimately linked with the evolution of associative learning and with flexible reward systems based on, and modifiable by, learning. During associative learning, new pathways relating stimuli and effects are formed within a highly integrated and continuously active nervous system. We argue that the memory traces left by such new stimulus-effect relations form dynamic, flexible, and varied global sensory (...) states, which we call categorizing sensory states . These CSSs acquired a function: they came to act as internal “evaluators” and led to positive and negative reinforcement of new behavior. They are therefore the simplest, distinct, first-person motivational states that an animal can have. They constitute what we call basic consciousness, and are the hallmark of animals that can experience. Since associative learning has been found in many invertebrate taxa that first appeared during the Cambrian era, we propose that the processes underlying basic consciousness are phylogenetically ancient, and that their emergence may have fueled the Cambrian explosion.

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

Is phenomenal consciousness a problem for the brain sciences? An increasing number of researchers hold not only that it is but that its very existence is a deep mystery. That this problematic phenomenon exists is generally taken for granted: It is asserted that phenomenal consciousness is just phenomenologically obvious. In contrast, I hold that there is no such phenomenon and, thus, that it does not pose a problem for the brain sciences. For this denial to be plausible, however, I need (...) to show that phenomenal consciousness is not phenomenologically obvious. That is the goal of this article. †To contact the author, please write to: 1414 Simona Drive, Pittsburgh, PA 15201; e‐mail: [email protected]. (shrink)

We seem to directly perceive external things. But can we? According to the time‐lag argument, we cannot. What we directly perceive happens now. There is a time‐lag between our perceptions and the external things we seem to directly perceive; these external things happen in the past; thus, what we directly perceive must be something else, for example, sense‐data, and we can only at best indirectly perceive other things. This paper examines the time‐lag argument given contemporary metaphysics. I argue that this (...) argument is not as compelling as it may initially seem. First, it denies that what we directly perceive can ever be what it seems to be; second, it conflicts with the current physical conception of time, relativity theory. This latter point leads to a more general one: the argument's force depends on a particular metaphysical conception on time, presentism, which is controversial in contemporary metaphysics of time. Given the alternative conception, eternalism, the argument is much less compelling. The overall argument of this paper, then, is that, if one wishes to hold that we directly perceive external things, we should subscribe to the latter view of time, i.e., eternalism. (shrink)

Purpose: Constructivism postulates that the perceived reality is a complex construct formed during development. Depending on the particular school, these inner constructs take on different forms and structures and affect cognition in different ways. The purpose of this article is to address the questions of how and, even more importantly, why we form such inner constructs. Approach: This article proposes that brain development is controlled by an inherent anticipatory drive, which biases learning towards the formation of forward predictive structures and (...) inverse goal-oriented control structures. This drive, in combination with increasingly complex environmental interactions during cognitive development, enforces the structuring of our conscious self, which is embedded in a constructed inner reality. Essentially, the following questions are addressed: Which basic mechanisms lead us to the construction of inner realities? How are these emergent inner realities structured? How is the self represented within the inner realities? And consequently, which cognitive structures constitute the media for conscious thought and selfconsciousness? Findings: Due to the anticipatory drive, representations in the brain shape themselves predominantly purposefully or intentionally. Taking a developmental, evolutionary perspective, we show how the brain is forced to develop progressively complex and abstract representations of the self embedded in the constructed inner realities. These self representations can evoke different stages of self-consciousness. Implications: The anticipatory drive shapes brain structures and cognition during the development of progressively more complex, competent, and flexible goal-oriented bodyenvironment interactions. Self-consciousness develops because increasingly abstract, individualizing self representations are necessary to realize these progressively more challenging environmental interactions. (shrink)

Perceptual constancy, often defined as the perception of stable features under changing conditions, goes hand in hand with variation in how things look. A white wall in the orange afternoon sun still looks white, though its whiteness looks different compared with the same wall in the noon sun. Historically, this variation has often been explained in terms of our experience of “merely sensory” or subjective properties – an approach at odds with the fact that the variation does track objective features (...) of the perceptual situation, such as illumination. One approach, becoming more common, is to account for the variation in terms of further “dimensions” to perceptual experience. Especially in colour perception, this is a natural thought to have but the idea is often left vague. In this paper I argue that the “dimensional” strategy has problems of its own, but is useful in drawing out some interesting complications in the way perceptual experience is structured. Specifically, the structure of “constancy spaces” brings out the different ways in which there is stability and instability in the experience of constancy, without the need for novel or merely subjective features. Instability arises in a contingent structural feature of perceptual experience. (shrink)

A systematic theory of naturalism, bridging metaphysics and the science of complexity and emergence.

In this article, I argue that the relationship between place and self can be accounted for by recent theoretical work on autobiographical memory. The link between place and self is conceptualized as a transitory mental representation that emerges as a “place of mine” (personal autobiographical experience) from a “place” (declarative knowledge). The function of “place of mine” is to guide personal memory and self-knowing consciousness of periods of our lives. I combine inquiries of memory, self, and place in a triadic (...) relationship, a synthesis, suggesting a conceptual model for the phenomenon of place-related self as a sub-system of the self. This is formed by a causal progression from a physical place across time via emotional and cognitive bonds, components of the autobiographical information grounding the self, apportioned across declarative memory. Finally, using the methods of factor analysis and structural equation modeling, I show that the proposed model accounts for previous and new data on place-related identity. (shrink)

This book presents a comprehensive theoretical framework that explains both human consciousness and meanings through the working of attention. By arguing for a first-person approach to consciousness, this book offers a critical overview of the major theories and empirical findings on consciousness and attention, and exemplifies how one of the most difficult and fundamental conscious experiences to account for, that is, time, can be analyzed by adopting the kind of semantics developed within the presented theoretical framework: Attentional Semantics.

In this attempt to deal with the problem of free will Tallis identifies intentionality as a feature of our lives that cannot be explained by deterministic, natural, physical, causal laws. Our ability to think about the world, and not merely be objects subject to it, gives us room for manoeuvre for free thought and action. Science, far from being antagonistic to the possibility of free will as it is usually presented through its deterministic explanations, is a manifestation of our freedom (...) and could not exist without it. However, doubts arise for the argument owing to a lack of explanation as to how freedom is possible no matter how persuasively we are shown that it appears to be. That is, what kind of world would it have to be for freedom to exist and be explicable. I conclude with my own view, alluded to by Tallis, but not followed up, that the problem with the scientific worldview is that it is wedded to objectivity as the only stance deemed veridical as to the nature of reality, one which therefore cannot by necessity allow subjects or freedom. As freedom is a property of subjects, the scientific worldview cannot allow for freedom. Once the condition is dropped that only the objectively knowable can be real, freedom also may be real, defined as a knowable property of our subjectivity. There is no need to deny physicalism if the definition of it is released from the epistemic bonds of objectivity and we hold that some physical properties may be known subjectively, namely those that characterize our subjective life.

Human “free will” has been made problematic by several recent arguments against mental causation, the unity of the I or “self,” and the possibility that conscious decision-making could be temporally prior to action. This paper suggests a pathway through this thicket for free will or self-determination. Doing so requires an account of mind as an emergent process in the context of animal psychology and mental causation. Consciousness, a palpable but theoretically more obscure property of some minds, is likely to derive (...) from complex animals’ real-time monitoring of internal state in relation to environment. Following Antonio Damasio, human mind appears to add to nonhuman “core consciousness” an additional narrative “self-consciousness.” The neurological argument against free will, most famously from Benjamin Libet, can be avoided as long as “free will” means, not an impossible event devoid of prior causation, but an occasional causal role played by narrative self-consciousness in behavioral determination. There is no necessary incompatibility between the scientific and evolutionary exploration of mind and consciousness and the uniquely self-determining capabilities of human mentality which are based on the former.

Bering's argument that human beings are endowed with a cognitive system dedicated to forming illusory representations of psychological immortality relies on the claim that children's beliefs in the afterlife are not the result of religious teaching. We suggest four reasons why this claim is unsatisfactory.

Robert Brandom's book Between Saying and Doing: Towards an Analytic Pragmatism does not incorporate the larger views of any of the “pragmatisms” he deliberately invokes, such as those of the classical American pragmatists, apart from an “analytic” cohort of Wittgenstein-inspired pragmatisms that he himself favors.

The primary determinant of the self (S) is the conscious experience (CE) we have of it. Therefore, it does not come as a surprise that empirical research on S mainly resorts to the CE (or lack of CE) that subjects have of their S. What comes as a surprise is that empirical research on S does not tackle the problem of how CE contributes to building S. Empirical research investigates how S either biases the cognitive processing of stimuli or is (...) altered through a wide range of means (meditation, hypnosis, etc.). In either case, even for different reasons, considerations of how CE contributes to building S are left unspecified in empirical research. This article analyzes these reasons and proposes a theoretical model of how CE contributes to building S. According to the proposed model, the phenomenal aspect of consciousness is produced by the modulation—engendered by attentional activity—of the energy level of the neural substrate (that is, the organ of attention) that underpins attentional activity. The phenomenal aspect of consciousness supplies the agent with a sense of S and informs the agent on how its S is affected by the agent’s own operations. The phenomenal aspect of consciousness performs its functions through its five main dimensions: qualitative, quantitative, hedonic, temporal, and spatial. Each dimension of the phenomenal aspect of consciousness can be explained by a specific aspect of the modulation of the energy level of the organ of attention. Among other advantages, the model explains the various forms of S as outcomes resulting from the operations of a single mechanism and provides a unifying framework for empirical research on the neural underpinnings of S.

Some theories of consciousness emphasize its relationship to language, its emergent quality, and its causal role. Prominent among these theories is the one that Dennett has been developing for nearly four decades. According to Dennett’s most recent version, consciousness is a kind of cerebral clout. But consideration of examples of pain—arguably the best candidate on offer for a paradigm of consciousness—reveals that clout is neither necessary nor sufficient for consciousness. Moreover, pain doesn’t necessarily have the aftermath that is predicted by (...) Dennett’s Clout Theory (CT); pain cannot always be accommodated by Dennett’s methodology; and, pain does not always conform to Dennett’s proposed ontology. Dennett might wish to substitute episodic memory as a preferred paradigm for consciousness, but episodic memory is shown to be non-essential. And, were it to be treated as a paradigm of consciousness, it would create new explanatory problems for CT. Rather than abandoning CT, because it does seem to help explain some pain phenomena and because it does comport well with certain views of language, I propose that some of its more intriguing proposals be retained and treated as hypotheses to guide further empirical inquiry. Finally, I recommend some specific empirical cases wherein relevant research might be pursued. (shrink)

Contemporary sciences use a wide and diverse range of computational simulations, including in the areas of aeronautics, chemistry, bioinformatics, social sciences, AI, the physics of elementary particles and most other scientific fields. A simulation is a mathematical model that describes or creates computationally a system process. Simulations are our best cognitive representation of complex reality, that is, our deepest conception of what reality is. In this paper we defend that a simulation is equivalent epistemologically and ontologically with all other types (...) of cognitive models of elements of reality. Therefore, simulations cannot be considered secondary nor weak instruments to approach to the reality analysis. (shrink)
