explain the nature of consciousness

[98] Rodolfo Llinás, for example, proposed that consciousness results from recurrent thalamo-cortical resonance where the specific thalamocortical systems (content) and the non-specific (centromedial thalamus) thalamocortical systems (context) interact in the gamma band frequency via synchronous oscillations. The nature of consciousness or human awareness is one of the problems to philosophers and psychologists alike. The Oxford Living Dictionary defines consciousness as "The state of being aware of and responsive to one's surroundings. He offers two ideas about the nature of consciousness. [1] Despite millennia of analyses, definitions, explanations and debates by philosophers and scientists, consciousness remains puzzling and controversial,[2] being "at once the most familiar and most mysterious aspect of our lives". We instinctively know that emotions come from a different “layer” of our nature than the one from which our physical sensations arise. [24] Descartes used conscientia the way modern speakers would use "conscience". [19] There were, however, many occurrences in Latin writings of the phrase conscius sibi, which translates literally as "knowing with oneself", or in other words "sharing knowledge with oneself about something". [132] LSD, mescaline, psilocybin, dimethyltryptamine, and others in this group can produce major distortions of perception, including hallucinations; some users even describe their drug-induced experiences as mystical or spiritual in quality. A-consciousness, on the other hand, is the phenomenon whereby information in our minds is accessible for verbal report, reasoning, and the control of behavior. This measure was shown to be higher in individuals that are awake, in REM sleep or in a locked-in state than in those who are in deep sleep or in a vegetative state,[106] making it potentially useful as a quantitative assessment of consciousness states. What could be better known to us than our own feelings and experiences? In several paradigms, such as the technique of response priming, the behavior of subjects is clearly influenced by stimuli for which they report no awareness, and suitable experimental manipulations can lead to increasing priming effects despite decreasing prime identification (double dissociation). I therefore propose a radically different approach. It even happens in a scientist who analyses various phenomena in the world, or analyses the material body including the organ brain. [150][151][152], Despite the large amount of information available, many important aspects of perception remain mysterious. If you can't explain consciousness in terms of the existing fundamentals — space, time, mass, charge — then as a matter of logic, you need to expand the list. It has been disputed, however, whether there is enough evidence to count these as physiologically distinct states of consciousness. Signals arising from sensory organs are transmitted to the brain and then processed in a series of stages, which extract multiple types of information from the raw input. alan watts: the nature of consciousness, pt 3 of 3 In last night's session, I was discussing an alternative myth to the Ceramic and Fully Automatic models of the universe, I'll call the Dramatic Myth. Most writers on the philosophy of consciousness have been concerned with defending a particular point of view, and have organized their material accordingly. It is difficult to assess these somewhat exotic approaches at present. Finally, anger may inhibit any spiritual feelings while it is present. is too loaded with spurious connotations to be meaningful; but he proposed to replace all such questions with a specific operational test, which has become known as the Turing test. The second class, emotions, has a distinctively different “feel” than the first. Attention is a style of information processing in which a brain focuses its resources on a limited set of interrelated signals. This happens only because we were not aware of our real feelings. In the literal sense, "conscientia" means knowledge-with, that is, shared knowledge. [160] Also, bioethicists may be concerned with the ethical implications of consciousness in medical cases of patients such as the Karen Ann Quinlan case,[161] while neuroscientists may study patients with impaired consciousness in hopes of gaining information about how the brain works. The categories of feelings are useful to indicate the origin of a specific feeling, but then, the effect of a real feeling, particularly if it is intense, may spread to all the other layers of our self, bringing forth other feelings associated with the first. Broad, C. D. Mind and Its Place in Nature … The earliest English language uses of "conscious" and "consciousness" date back, however, to the 1500s. They describe consciousness or the ‘higher mind’ existing as a sphere or domain. Surprisingly, most people are not completely in touch with their own emotions. [160], Consciousness is of concern to patients and physicians, especially neurologists and anesthesiologists. [139], There has been some research into physiological changes in yogis and people who practise various techniques of meditation. [55] This is called the problem of other minds. This technique perhaps had its beginnings in the monologues of Shakespeare's plays and reached its fullest development in the novels of James Joyce and Virginia Woolf, although it has also been used by many other noted writers.[175]. A perception is a state whereby a variety of content is represented in a true unity. If so, the patient is asked for name, current location, and current day and time. We could then simply define consciousness as the capacity to feel. [165][166] Differential diagnosis of these disorders is an active area of biomedical research. [40]. Dr. Eben Alexander, author of international phenomenon Proof of Heaven, shares the next phase of his journey to understand the true nature of consciousness and ways to cultivate a state of harmony with the universe and our higher purpose. [89] In medicine, consciousness is assessed as a combination of verbal behavior, arousal, brain activity and purposeful movement. [115] Donald Griffin suggests in his book Animal Minds a gradual evolution of consciousness. The abstract noun “consciousness” is not frequently used by itself in the contemporary literature, but is originally derived from the Latin con (with) and scire (to know). It is called Consciousness. Although some philosophers, such as Daniel Dennett, have disputed the validity of this distinction,[36] others have broadly accepted it. Many philosophers consider experience to be the essence of consciousness, and believe that experience can only fully be known from the inside, subjectively. Obviously not all kinds of information are capable of being disseminated consciously (e.g., neural activity related to vegetative functions, reflexes, unconscious motor programs, low-level perceptual analyses, etc.) This book not only explains what and how but also why there are animal nature, human nature, and divine nature. During ordinary non-dream sleep, people who are awakened report only vague and sketchy thoughts, and their experiences do not cohere into a continuous narrative. Opinions are divided as to where in biological evolution consciousness emerged and about whether or not consciousness has any survival value. The topic of free will is the philosophical and scientific examination of this conundrum. Thus, we propose that critical to the nature and origin of consciousness is that with the addition of the special features to the general features, there occurred a transition from reflexes to conscious mental images and affects, and it was at that point that subjectivity, the philosophical “explanatory gaps,” and the hard problem were all naturally created . Since consciousness is reflexively aware of itself, it does not depend on some other cognizer [for consciousness itself to be known], unlike the case of blue and so on. Some altered states occur naturally; others can be produced by drugs or brain damage. I should perceive the object like a “picture of that object” existing only within my head, not in the space in front of me. When the intensity of our thoughts or emotions are close to normal, we feel next to nothing, and since we confuse thoughts and emotions, we often believe that a thought may change how we feel. We can see these three questions as clustering around the status of what we can call the unity thesis (UT): In philosophy, phenomenology has largely been devoted to fundamental metaphysical questions, such as the nature of intentionality ("aboutness"). There are also a variety of circumstances that can change the relationship between the mind and the world in less drastic ways, producing what are known as altered states of consciousness. The patient lacks awareness, sleep-wake cycles, and brain-mediated reflexive behavior. [173] The teachings list six triggers that can result in the generation of different mental events. The two main types of dualism are substance dualism (which holds that the mind is formed of a distinct type of substance not governed by the laws of physics) and property dualism (which holds that the laws of physics are universally valid but cannot be used to explain the mind). In the past, it was one's "inner life", the world of introspection, of private thought, imagination and volition. The English word "conscious" originally derived from the Latin conscius (con- "together" and scio "to know"), but the Latin word did not have the same meaning as the English word—it meant "knowing with", in other words, "having joint or common knowledge with another". When questioned about the obvious problem, the patient may avoid giving a direct answer, or may give an explanation that doesn't make sense. The outcome may be summarized using the Glasgow Coma Scale, which yields a number in the range 3–15, with a score of 3 to 8 indicating coma, and 15 indicating full consciousness. The mystery of … Audit of Humankind explains the three concepts in a secular fashion. The assumption of an avian consciousness also brings the reptilian brain into focus. [141] Each of these, in his view, could be altered in multiple ways by drugs or other manipulations. Faggin received many international awards, including the 2009 National Medal of Technology and Innovation, from President Barack Obama. [89] For one thing, if verbal reports are treated as observations, akin to observations in other branches of science, then the possibility arises that they may contain errors—but it is difficult to make sense of the idea that subjects could be wrong about their own experiences, and even more difficult to see how such an error could be detected. Bayesian models of the brain are probabilistic inference models, in which the brain takes advantage of prior knowledge to interpret uncertain sensory inputs in order to formulate a conscious percept; Bayesian models have successfully predicted many perceptual phenomena in vision and the nonvisual senses. In The Nature of Consciousness, Mark Rowlands develops an innovative account of the nature of phenomenal consciousness, one that has significant consequences for attempts to find a place for it in the natural order. Modern medical and psychological investigations into consciousness are based on psychological experiments (including, for example, the investigation of priming effects using subliminal stimuli), and on case studies of alterations in consciousness produced by trauma, illness, or drugs. This is a common experience to every human being. A positive result proves that machine is conscious but a negative result proves nothing. [130] As a result, an exaptive explanation of consciousness has gained favor with some theorists that posit consciousness did not evolve as an adaptation but was an exaptation arising as a consequence of other developments such as increases in brain size or cortical rearrangement. Second, and even more importantly, working memory allows information to be integrated over time so that it can generate a stable representation of the world—Gerald Edelman expressed this point vividly by titling one of his books about consciousness The Remembered Present. Understanding the physical basis of qualities, such as redness or pain, has been particularly challenging. But this does not explain the origin or the nature of my ‘consciousness’. To this class belong fear, anger, sadness, curiosity, friendship, compassion, pride, greed, confusion, trust, self-will, shame, envy, and so on. It can do whatever we know how to order it to perform. Neuroscience studies all these brain correlations and some then ‘assume’ that this activity creates my consciousness. For example, when we have a strong emotion like rage or grief, no amount of thinking can make it vanish, even when we would very much like to do it, proving that thoughts neither cause nor change real emotions. There is our experience, what we are conscious of, the contents of consciousness; and there is consciousness as a faculty, the faculty of being … [3] Perhaps the only widely agreed notion about the topic is the intuition that it exists. Another way of putting the argument is to say that computer programs can pass the Turing test for processing the syntax of a language, but that the syntax cannot lead to semantic meaning in the way strong AI advocates hoped. Welcome to the original site of Journal Psyche.Established in 1992, Psyche was a free, online publication exploring the nature of consciousness and its relation to the brain. [159], The medical approach to consciousness is practically oriented. This consciousness can be shown to have a physical effect in the collapse of the de Broglie wavefunction of a travelling particle. The nature of consciousness plays a key role in the philosophy of mind. Modulation of neural responses may correlate with phenomenal experiences. The Explanation expounds Human nature, Consciousness, and Mind in two books. [103] An fMRI investigation suggested that these findings were strictly limited to the primary visual areas. I hypothesize that consciousness is a fundamental property of the quantum fields not yet acknowledged by physics. The common usage definitions of consciousness in Webster's Third New International Dictionary (1966 edition, Volume 1, page 482) are as follows: The Cambridge Dictionary defines consciousness as "the state of understanding and realizing something. Zelazo, M. Moscovitch, and E. Thompson (eds. If so, the next question is whether the patient can respond in a meaningful way to questions and commands. Although P-consciousness without A-consciousness is more widely accepted, there have been some hypothetical examples of A without P. Block, for instance, suggests the case of a "zombie" that is computationally identical to a person but without any subjectivity. Interestingly, a thought is generally not considered to be a type of feeling, but if I ask: “how do you know you had a thought?” you may recognize that you felt something vaguely cross your mental “screen,” leaving a faint “image,” a quale, with the essential meaning of that thought. "[68], "Convergent evidence indicates that non-human animals [...], including all mammals and birds, and other creatures, [...] have the necessary neural substrates of consciousness and the capacity to exhibit intentional behaviors."[69]. Nothing worth reading has been written on it.[30]. [147], In neuroscience, a great deal of effort has gone into investigating how the perceived world of conscious awareness is constructed inside the brain. There are some brain states in which consciousness seems to be absent, including dreamless sleep, coma, and death. According to James, the "stream of thought" is governed by five characteristics: [172], A similar concept appears in Buddhist philosophy, expressed by the Sanskrit term Citta-saṃtāna, which is usually translated as mindstream or "mental continuum". None of the quantum mechanical theories have been confirmed by experiment. The disparate range of research, notions and speculations raises doubts about whether the right questions are being asked. The Glasgow Coma Scale has three subscales, measuring the best motor response (ranging from "no motor response" to "obeys commands"), the best eye response (ranging from "no eye opening" to "eyes opening spontaneously") and the best verbal response (ranging from "no verbal response" to "fully oriented"). Instead, its sensory capacity stops at the electrical signals. by stating an evolutionary argument for mind-brain interaction implying that if the preservation and development of consciousness in the biological evolution is a result of natural selection, it is plausible that consciousness has not only been influenced by neural processes, but has had a survival value itself; and it could only have had this if it had been efficacious. David Chalmers has argued that A-consciousness can in principle be understood in mechanistic terms, but that understanding P-consciousness is much more challenging: he calls this the hard problem of consciousness. Recently, consciousness has also become a significant topic of interdisciplinary research in cognitive science, involving fields such as psychology, linguistics, anthropology,[11] neuropsychology and neuroscience. The third category is made of thoughts. [42], Although it is widely accepted that Descartes explained the problem cogently, few later philosophers have been happy with his solution, and his ideas about the pineal gland have especially been ridiculed. Many philosophers have argued that the theory is insufficient to account for consciousness because the role a mental state plays doesn’t explain why the state must be one that is conscious. Human nature defines humankind and consciousness as well as mind are the overriding elements of humans. [75] As an agent sees representation of itself recurring in the environment, the compression of this representation can be called consciousness. "Consciousness." Theories proposed by neuroscientists such as Gerald Edelman[46] and Antonio Damasio,[47] and by philosophers such as Daniel Dennett,[48] seek to explain consciousness in terms of neural events occurring within the brain. In the late 20th century, philosophers like Hamlyn, Rorty, and Wilkes have disagreed with Kahn, Hardie and Modrak as to whether Aristotle even had a concept of consciousness. The three main types of monism are physicalism (which holds that the mind consists of matter organized in a particular way), idealism (which holds that only thought or experience truly exists, and matter is merely an illusion), and neutral monism (which holds that both mind and matter are aspects of a distinct essence that is itself identical to neither of them). This property will be discussed in a later essay of this series. But feeling implies the existence of an entity that feels, an observer, a self. Both dream and non-dream states are associated with severe disruption of memory: it usually disappears in seconds during the non-dream state, and in minutes after awakening from a dream unless actively refreshed.[135]. [167][168][169] Finally, brain death results in an irreversible disruption of consciousness. It's obvious to everyone in this room that animals have consciousness, but it is not obvious to the rest of the world. In 2011, Graziano and Kastner[105] proposed the "attention schema" theory of awareness. One influential idea to explain the nature of consciousness is called global workspace theory. It seems that, from what we know, consciouss thought is a result of neurons firing in the brain in a certain pattern. For example, assuming that birds are conscious—a common assumption among neuroscientists and ethologists due to the extensive cognitive repertoire of birds—there are comparative neuroanatomical ways to validate some of the principal, currently competing, mammalian consciousness–brain theories. In medicine, conceptual distinctions are considered useful to the degree that they can help to guide treatments. However, it remains unspecified which kinds of information are integrated in a conscious manner and which kinds can be integrated without consciousness. [170] The most frequently occurring form is seen in people who have experienced a stroke damaging the parietal lobe in the right hemisphere of the brain, giving rise to a syndrome known as hemispatial neglect, characterized by an inability to direct action or attention toward objects located to the left with respect to their bodies. [66] Several psychologists and ethologists have argued for the existence of animal consciousness by describing a range of behaviors that appear to show animals holding beliefs about things they cannot directly perceive—Donald Griffin's 2001 book Animal Minds reviews a substantial portion of the evidence.[67]. It can follow analysis; but it has no power of anticipating any analytical relations or truths. A more straightforward way of saying this is that we attribute experiences to people because of what they can do, including the fact that they can tell us about their experiences. Unfortunately, precisely consciousness, of all things in the universe, still eludes scientists. Further, this account is easily modeled in computer programs that can examine, report on, and modify themselves on the basis of available information. Using the same premises, humans have been declared to be machines, at least in principle, because those same assumptions have been making excellent predictions about the inanimate world. The mystery of consciousness, according to Roger Penrose, the 89-year-old winner of the 2020 Nobel Prize in physics, will only be solved when an … The perceiver exists separately from the perceived. the memory of an emotion felt in the past, rather than an emotion lived in the present moment. It is one of the core properties that characterizes a self: it is its capacity to perceive and know through feelings, through a sentient experience.
