In philosophy of science and philosophy of mind, cognitive closure is the proposition that human minds are constitutionally incapable of solving certain perennial philosophical problems. [1] Owen Flanagan calls this position anti-constructive naturalism or the "new mysterianism" and the primary advocate of the hypothesis, Colin McGinn, [2] [3] calls it transcendental naturalism acknowledging the possibility that solutions may be knowable to an intelligent non-human of some kind. According to McGinn, such philosophical questions include the mind-body problem, identity of the self, foundations of meaning, free will, and knowledge, both a priori and empirical. [4]
It cannot be simply taken for granted that the human reasoning faculty is naturally suited for answering philosophical questions: the questions and their subject matter are one thing; and rational faculty, as a human trait, is another. From the fact that it is the best faculty we have… for doing philosophy it does not follow that it is a remotely good or adequate faculty for that purpose. [5]
— Colin McGinn, Problems in Philosophy: The Limits of Inquiry
When human minds interact with philosophical problems, especially those of the form 'How is X possible?', they are apt to go into one of four possible states. Either (i) they try to domesticate the object of puzzlement by providing a reductive or explanatory theory of it; or (ii) they declare it irreducible and hence not open to any levelling account; or (iii) they succumb to a magical story or image of what seems so puzzling; or (iv) they simply eliminate the source of trouble for fear of ontological embarrassment... The topics on which it imprints itself, and which I have discussed in some diagnostic detail in the aforementioned book, include: consciousness and the mind-body problem, the nature and identity of the self, the foundations of meaning, the possibility of free will, the availability of a priori and empirical knowledge... Basically what we find, quite generally, is the threat of magic or elimination in the face of the theoretical obduracy of the phenomenon that invites philosophical attention. The phenomenon presents initial problems of possibility... Free will, for instance, looks upon early inspection to be impossible, so we try to find some conception of it that permits its existence, but this conception always turns out to be dubiously reductive and distorting, leaving us with the unpalatable options of magic, elimination or quietism... so we hop unhappily from one unsatisfactory option to the next; or dig our heels (squintingly) into a position that seems the least intellectually unconscionable of the bunch... Science, then, might be aptly characterised as that set of questions that does not attract [these] options – where our cognitive faculties allow us to form the necessary concepts and theories. The distinction between science and philosophy is, on this view, at root a reflection of the cognitive powers we happen to possess or lack, and is therefore creature-relative: it does not correspond to any interesting real division within objective reality... It is not beyond the bounds of possibility that our brains would have to be made of something other than neurons in order for us to have the kinds of cognitive powers needed to solve the problems philosophy poses; at any rate, this is the sort of diagnosis [transcendental naturalism] offers for our philosophical retardation... The hardness of philosophy is thus an upshot of the particular way that natural selection has built our thinking organ, not an objective trait of the subject-matter of philosophical questions. [4]

For Friedrich Hayek, "The whole idea of the mind explaining itself is a logical contradiction"... and "takes this incompleteness—the constitutional inability of mind to explain itself—to be a generalized case of Gödel's incompleteness theorem... Hayek is not a naturalistic agnostic, that is, the view that science currently cannot offer an explanation of the mind-body relationship, but in principle it could." [6]
[The] passage from the physics of the brain to the corresponding facts of consciousness is unthinkable. Granted that a definite thought, and a definite molecular action in the brain occur simultaneously; we do not possess the intellectual organ, nor apparently any rudiment of the organ, which would enable us to pass, by a process of reasoning, from the one to the other. They appear together, but we do not know why. Were our minds and senses so expanded, strengthened, and illuminated, as to enable us to see and feel the very molecules of the brain; were we capable of following all their motions, all their groupings, all their electric discharges, if such there be; and were we intimately acquainted with the corresponding states of thought and feeling, we should be as far as ever from the solution of the problem, "How are these physical processes connected with the facts of consciousness?" The chasm between the two classes of phenomena would still remain intellectually impassable. Let the consciousness of love, for example, be associated with a right-handed spiral motion of the molecules of the brain, and the consciousness of hate with a left-handed spiral motion. We should then know, when we love, that the motion is in one direction, and, when we hate, that the motion is in the other; but the "Why?" would remain as unanswerable as before. [7]

Noam Chomsky argues that the cognitive capabilities of all organisms are limited by biology and that certain problems may be beyond our understanding:
A Martian scientist, with a mind different from ours might regard this problem [of free will] as trivial, and wonder why humans never seem to hit on the obvious way of solving it. This observer might also be amazed at the ability of every human child to acquire language, something that seems to him incomprehensible, requiring divine intervention. [8]

As argued in Kant's Critique of Pure Reason , human thinking is unavoidably structured by categories of the understanding:
Quantity – Unity, Plurality, Totality.
Quality – Reality, Negation, Limitation.
Relation – Inherence and Subsistence, Causality and Dependence, Community.
Modality – Possibility or Impossibility, Existence or Non-Existence, Necessity or Contingence.
These are ideas from which there is no escape and thus they pose a limit to thinking. What can be known through the categories is called "things for us" and what is outside the categories is unthinkable, called "things in themselves".
In his (famous) essay "What Is It Like to Be a Bat?" Thomas Nagel mentions the possibility of cognitive closure to the subjective character of experience and the (deep) implications that it has for materialist reductionist science. Owen Flanagan noted in his 1991 book Science of the Mind that some modern thinkers have suggested that consciousness will never be completely explained. Flanagan called them "the new mysterians" after the rock group Question Mark and the Mysterians. [9] According to McGinn, the solution to the mind-body problem cannot be grasped, despite the fact that the solution is "written in our genes".
Emergent materialism is a similar but different claim that humans are not yet smart enough to determine the relationship between mind and matter.[ citation needed ][ dubious – discuss ]
Cognitive science is the interdisciplinary, scientific study of the mind and its processes. It examines the nature, the tasks, and the functions of cognition. Mental faculties of concern to cognitive scientists include perception, memory, attention, reasoning, language, and emotion; to understand these faculties, cognitive scientists borrow from fields such as psychology, artificial intelligence, philosophy, neuroscience, linguistics and anthropology. The typical analysis of cognitive science spans many levels of organization, from learning and decision-making to logic and planning; from neural circuitry to modular brain organization. One of the fundamental concepts of cognitive science is that "thinking can best be understood in terms of representational structures in the mind and computational procedures that operate on those structures."
The Chinese room argument holds that a computer executing a program cannot have a mind, understanding, or consciousness, regardless of how intelligently or human-like the program may make the computer behave. The argument was presented in a 1980 paper by the philosopher John Searle entitled "Minds, Brains, and Programs" and published in the journal Behavioral and Brain Sciences. Before Searle, similar arguments had been presented by figures including Gottfried Wilhelm Leibniz (1714), Anatoly Dneprov (1961), Lawrence Davis (1974) and Ned Block (1978). Searle's version has been widely discussed in the years since. The centerpiece of Searle's argument is a thought experiment known as the Chinese room.
Materialism is a form of philosophical monism which holds that matter is the fundamental substance in nature, and that all things, including mental states and consciousness, are results of material interactions of material things. According to philosophical materialism, mind and consciousness are caused by physical processes, such as the neurochemistry of the human brain and nervous system, without which they cannot exist. Materialism directly contrasts with monistic idealism, according to which consciousness is the fundamental substance of nature.
The philosophy of perception is concerned with the nature of perceptual experience and the status of perceptual data, in particular how they relate to beliefs about, or knowledge of, the world. Any explicit account of perception requires a commitment to one of a variety of ontological or metaphysical views. Philosophers distinguish internalist accounts, which assume that perceptions of objects, and knowledge or beliefs about them, are aspects of an individual's mind, and externalist accounts, which state that they constitute real aspects of the world external to the individual. The position of naïve realism—the 'everyday' impression of physical objects constituting what is perceived—is to some extent contradicted by the occurrence of perceptual illusions and hallucinations and the relativity of perceptual experience as well as certain insights in science. Realist conceptions include phenomenalism and direct and indirect realism. Anti-realist conceptions include idealism and skepticism. Recent philosophical work have expanded on the philosophical features of perception by going beyond the single paradigm of vision.
In the philosophy of mind, mind–body dualism denotes either the view that mental phenomena are non-physical, or that the mind and body are distinct and separable. Thus, it encompasses a set of views about the relationship between mind and matter, as well as between subject and object, and is contrasted with other positions, such as physicalism and enactivism, in the mind–body problem.
Owen Flanagan is the James B. Duke University Professor Emeritus of Philosophy and Professor of Neurobiology Emeritus at Duke University. Flanagan has done work in philosophy of mind, philosophy of psychology, philosophy of social science, ethics, contemporary ethical theory, moral psychology, as well as on cross-cultural philosophy.
In the philosophy of mind, the explanatory gap is the difficulty that physicalist philosophies have in explaining how physical properties give rise to the way things feel subjectively when they are experienced. It is a term introduced by philosopher Joseph Levine. In the 1983 paper in which he first used the term, he used as an example the sentence, "Pain is the firing of C fibers", pointing out that while it might be valid in a physiological sense, it does not help us to understand how pain feels.
Patricia Smith Churchland is a Canadian-American analytic philosopher noted for her contributions to neurophilosophy and the philosophy of mind. She is UC President's Professor of Philosophy Emerita at the University of California, San Diego (UCSD), where she has taught since 1984. She has also held an adjunct professorship at the Salk Institute for Biological Studies since 1989. She is a member of the Board of Trustees Moscow Center for Consciousness Studies of Philosophy Department, Moscow State University. In 2015, she was elected a Fellow of the American Academy of Arts & Sciences. Educated at the University of British Columbia, the University of Pittsburgh, and Somerville College, Oxford, she taught philosophy at the University of Manitoba from 1969 to 1984 and is married to the philosopher Paul Churchland. Larissa MacFarquhar, writing for The New Yorker, observed of the philosophical couple that: "Their work is so similar that they are sometimes discussed, in journals and books, as one person."
Colin McGinn is a British philosopher. He has held teaching posts and professorships at University College London, the University of Oxford, Rutgers University, and the University of Miami.
In the philosophy of mind, the hard problem of consciousness is to explain why and how humans and other organisms have qualia, phenomenal consciousness, or subjective experience. It is contrasted with the "easy problems" of explaining why and how physical systems give a (healthy) human being the ability to discriminate, to integrate information, and to perform behavioral functions such as watching, listening, speaking, and so forth. The easy problems are amenable to functional explanation—that is, explanations that are mechanistic or behavioral—since each physical system can be explained purely by reference to the "structure and dynamics" that underpin the phenomenon.
New mysterianism, or commonly just mysterianism, is a philosophical position proposing that the hard problem of consciousness cannot be resolved by humans. The unresolvable problem is how to explain the existence of qualia. In terms of the various schools of philosophy of mind, mysterianism is a form of nonreductive physicalism. Some "mysterians" state their case uncompromisingly ; others take a "pseudo-mysterian" stance, being of the belief that consciousness is not within the grasp of present human understanding, but may be comprehensible to future advances of science and technology.
Neurophenomenology refers to a scientific research program aimed to address the hard problem of consciousness in a pragmatic way. It combines neuroscience with phenomenology in order to study experience, mind, and consciousness with an emphasis on the embodied condition of the human mind. The field is very much linked to fields such as neuropsychology, neuroanthropology and behavioral neuroscience and the study of phenomenology in psychology.
In the philosophy of mind, innatism is the view that the mind is born with already-formed ideas, knowledge, and beliefs. The opposing doctrine, that the mind is a tabula rasa at birth and all knowledge is gained from experience and the senses, is called empiricism.
The philosophy of artificial intelligence is a branch of the philosophy of mind and the philosophy of computer science that explores artificial intelligence and its implications for knowledge and understanding of intelligence, ethics, consciousness, epistemology, and free will. Furthermore, the technology is concerned with the creation of artificial animals or artificial people so the discipline is of considerable interest to philosophers. These factors contributed to the emergence of the philosophy of artificial intelligence.
Metaphysical naturalism is a philosophical worldview which holds that there is nothing but natural elements, principles, and relations of the kind studied by the natural sciences. Methodological naturalism is a philosophical basis for science, for which metaphysical naturalism provides only one possible ontological foundation. Broadly, the corresponding theological perspective is religious naturalism or spiritual naturalism. More specifically, metaphysical naturalism rejects the supernatural concepts and explanations that are part of many religions.
Plato's problem is the term given by Noam Chomsky to "the problem of explaining how we can know so much" given our limited experience. Chomsky believes that Plato asked how we should account for the rich, intrinsic, common structure of human cognition, when it seems underdetermined by extrinsic evidence presented to a person during human development. In linguistics this is referred to as the "argument from poverty of the stimulus" (APS). Such arguments are common in the natural sciences, where a developing theory is always "underdetermined by evidence". Chomsky's approach to Plato's problem involves treating cognition as a normal research topic in the natural sciences, so cognition can be studied to elucidate intertwined genetic, developmental, and biophysical factors. Plato's problem is most clearly illustrated in the Meno dialogue, in which Socrates demonstrates that an uneducated boy nevertheless understands geometric principles.
The philosophy of mind is a branch of philosophy that deals with the nature of the mind and its relation to the body and the external world.
The evolutionary argument against naturalism (EAAN) is a philosophical argument asserting a problem with believing both evolution and philosophical naturalism simultaneously. The argument was first proposed by Alvin Plantinga in 1993 and "raises issues of interest to epistemologists, philosophers of mind, evolutionary biologists, and philosophers of religion". The EAAN argues that the combined belief in both evolutionary theory and naturalism is epistemically self-defeating. The argument for this is that if both evolution and naturalism are true, then the probability of having reliable cognitive faculties is low, which then destroys any reason to believe in evolution or naturalism in the first place, as the cognitive faculties one used to deduce evolution or naturalism as logically valid are no longer reliable. This argument comes as an expansion of the argument from reason, although the two are separate philosophical arguments.
The mind–body problem is a philosophical problem concerning the relationship between thought and consciousness in the human mind and body.
Epistemology or theory of knowledge is the branch of philosophy concerned with the nature and scope (limitations) of knowledge. It addresses the questions "What is knowledge?", "How is knowledge acquired?", "What do people know?", "How do we know what we know?", and "Why do we know what we know?". Much of the debate in this field has focused on analyzing the nature of knowledge and how it relates to similar notions such as truth, belief, and justification. It also deals with the means of production of knowledge, as well as skepticism about different knowledge claims.
McGinn's stance, while he denies the possibility of ever understanding the causal connection, may be regarded as "naturalistic" in the sense that he does not reject the validity of neuro-physiological theory, and does not doubt that brain activity accompanies conscious states..
It combines deep epistemic transcendence with the denial that what thus transcends is thereby non-natural.
There is, I believe, a systematic pattern to philosophical disputation, in which the same kinds of unsatisfying alternatives recur.
1. Explanation is delimited by the apparatus of classification (the mind)... 2. An apparatus of classification cannot explain anything more complex than itself... 3. Therefore, the mind cannot fully explain itself...
