Mind–body problem
From Wikipedia, the free encyclopedia
See also: Philosophy of mind
The mind–body problem is the problem of explaining how mental states, events and processes—like beliefs, actions and thinking—are related to the physical states, events and processes, given that the human body is a physical entity and the mind is non-physical.[1]
The problem was addressed by René Descartes in the 17th century, resulting in Cartesian dualism, and by pre-Aristotelian philosophers,[2][3] inAvicennian philosophy,[4] and in earlier Asian traditions. A variety of approaches have been proposed. Most are either dualist or monist. Dualism maintains a rigid distinction between the realms of mind and matter. Monism maintains that there is only one unifying reality, substance or essence in terms of which everything can be explained.
Each of these categories contain numerous variants. The two main forms 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 mental properties involving conscious experience are fundamental properties, alongside the fundamental properties identified by a completed physics. The three main forms of monism are physicalism, which holds that the mind consists of matter organized in a particular way; idealism, which holds that only thought 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.
Several philosophical perspectives have been developed which reject the mind–body dichotomy. The historical materialism of Karl Marx and subsequent writers, itself a form of physicalism, held that consciousness was engendered by the material contingencies of one's environment.[5] An explicit rejection of the dichotomy is found in French structuralism, and is a position that generally characterized post-war French philosophy.[6]
The absence of an empirically identifiable meeting point between the non-physical mind and its physical extension has proven problematic to dualism and many modern philosophers of mind maintain that the mind is not something separate from the body.[7] These approaches have been particularly influential in the sciences, particularly in the fields of sociobiology, computer science, evolutionary psychology, and the neurosciences.[8][9][10][11]

[hide]Mind–body interaction and mental causation[edit]
Philosophers David L. Robb and John H. Heil introduce mental causation in terms of the mind–body problem of interaction:
Contemporary neurophilosopher, Georg Northoff suggests that mental causation is compatible with classical formal and final causality.[13]
Biologist, theoretical neuroscientist and philosopher, Walter J. Freeman, suggests that explaining mind–body interaction in terms of "circular causation" is more relevant than linear causation.[14]
In neuroscience, much has been learned about correlations between brain activity and subjective, conscious experiences. Many suggest that neuroscience will ultimately explain consciousness: "...consciousness is a biological process that will eventually be explained in terms of molecular signaling pathways used by interacting populations of nerve cells..."[15] However, this view has been criticized becauseconsciousness has yet to be shown to be a process,[16] and the "hard problem" of relating consciousness directly to brain activity remains elusive.[17]
One possible explanation of the mind-body problem and the problem of consciousness is that they both arise as an illusion caused by the mind-recognition mechanism that evolved to facilitate social and moral behaviors. There is an evolutionary advantage to perceive other humans differently than fragments of tissues. Human brains are hard-wired to place humans and meat in two separate categories. This makes it natural to think in terms of mind-body duality while making it intellectually hard to accept identity between a mind and an underlying tissue. Thus, the mental causation question is ill-posed. The question is not how mind affects the brain but how the brain structure affects our perception.[19]
Neural correlates[edit]
Main article: Neural correlates of consciousness
The neural correlates of consciousness "are the smallest set of brain mechanisms and events sufficient for some specific conscious feeling, as elemental as the color red or as complex as the sensual, mysterious, and primeval sensation evoked when looking at [a] jungle scene..."[21] Neuroscientists use empirical approaches to discover neural correlates of subjective phenomena.[22]
Neurobiology and neurophilosophy[edit]
Main articles: Neurobiology and Neurophilosophy
A science of consciousness must explain the exact relationship between subjective conscious mental states and brain states formed by electrochemical interactions in the body, the so-called hard problem of consciousness.[23] Neurobiology studies the connection scientifically, as do neuropsychology and neuropsychiatry. Neurophilosophy is the interdisciplinary study of neuroscience and philosophy of mind. In this pursuit, neurophilosophers, such as Patricia Churchland, [24][25] Paul Churchland[26] and Daniel Dennett,[27][28] have focused primarily on the body rather than the mind. In this context, neuronal correlates may be viewed as causing consciousness, where consciousness can be thought of as an undefined property that depends upon this complex, adaptive, and highly interconnected biological system.[29] However, it's unknown if discovering and characterizing neural correlates may eventually provide a theory of consciousness that can explain the first-person experience of these "systems", and determine whether other systems of equal complexity lack such features.
The massive parallelism of neural networks allows redundant populations of neurons to mediate the same or similar percepts. Nonetheless, it is assumed that every subjective state will have associated neural correlates, which can be manipulated to artificially inhibit or induce the subject's experience of that conscious state. The growing ability of neuroscientists to manipulate neurons using methods from molecular biology in combination with optical tools[30] was achieved by the development of behavioral and organic models that are amenable to large-scale genomic analysis and manipulation. Non-human analysis such as this, in combination with imaging of the human brain, have contributed to a robust and increasingly predictive theoretical framework.
Arousal and content[edit]
There are two common but distinct dimensions of the termconsciousness,[32] one involvingarousal and states of consciousnessand the other involving content of consciousness and conscious states. To be conscious of something, the brain must be in a relatively high state of arousal (sometimes calledvigilance), whether awake or inREM sleep. Brain arousal level fluctuates in a circadian rhythm but these natural cycles may be influenced by lack of sleep, alcohol and other drugs, physical exertion, etc. Arousal can be measured behaviorally by the signal amplitude required to trigger a given reaction (for example, the sound level that causes a subject to turn and look toward the source). High arousal states involve conscious states that feature specific perceptual content, planning and recollection or even fantasy. Clinicians use scoring systems such as theGlasgow Coma Scale to assess the level of arousal in patients withimpaired states of consciousness such as the comatose state, thepersistent vegetative state, and the minimally conscious state. Here, "state" refers to different amounts of externalized, physical consciousness: ranging from a total absence in coma, persistent vegetative state and general anesthesia, to a fluctuating, minimally conscious state, such as sleep walking and epileptic seizure.[33]
Many nuclei with distinct chemical signatures in the thalamus, midbrainand pons must function for a subject to be in a sufficient state of brain arousal to experience anything at all. These nuclei therefore belong to the enabling factors for consciousness. Conversely it is likely that the specific content of any particular conscious sensation is mediated by particular neurons in the cortex and their associated satellite structures, including the amygdala, thalamus, claustrum and the basal ganglia.
Historical background[edit]
The following is a very brief account of some contributions to the mind–body problem.
The Buddha[edit]
The Buddha (480-400 B.C.E), founder of Buddhism, did not make a distinction between the mind and the body[34] and taught that the world consists of mind and matter which work together, interdependently. Ultimately, the Buddha's philosophy is that both mind and forms are conditionally arising qualities of an ever-changing universe in which, when nirvāna is attained, all phenomenal experience ceases to exist.[35] According to the anattā doctrine of the Buddha, the conceptual self is a mere mental construct of an individual entity and is basically an impermanent illusion, sustained by form, sensation, perception, thought and consciousness.[36] The Buddha argued that mentally clinging to any views will result in delusion and stress,[37]since, according to the Buddha, a real self (conceptual self, being the basis of standpoints and views) cannot be found when the mind has clarity.
Plato[edit]
See also: Plato and Theory of forms
Plato (429–347 B.C.E.) believed that the material world is a shadow of a higher reality that consists of concepts he called Forms. According to Plato, objects in our everyday world "participate in" these Forms, which confer identity and meaning to material objects. For example, a circle drawn in the sand would be a circle only because it participates in the concept of an ideal circle that exists somewhere in the world of Forms. He argued that, as the body is from the material world, the soul is from the world of Forms and is thus immortal. He believed the soul was temporarily united with the body and would only be separated at death, when it would return to the world of Forms. Since the soul does not exist in time and space, as the body does, it can access universal truths. For Plato, ideas (or Forms) are the true reality, and are experienced by the soul. The body is for Plato empty in that it can not access the abstract reality of the world; it can only experience shadows. This is determined by Plato's essentially rationalisticepistemology.[citation needed]
Aristotle[edit]
Main article: Aristotle
For Aristotle (384–322 BC) mind is a faculty of the soul. Regarding the soul, he said:
In the end, Aristotle saw the relation between soul and body as uncomplicated, in the same way that it is uncomplicated that a cubical shape is a property of a toy building block. The soul is a property exhibited by the body, one among many. Moreover, Aristotle proposed that when the body perishes, so does the soul, just as the shape of a building block disappears with destruction of the block.[38]
Descartes[edit]
Main article: René Descartes
René Descartes (1596–1650) believed that mind exerted control over the brain via the pineal gland:
His posited relation between mind and body is called Cartesian dualismor substance dualism. He held that mind was distinct from matter, but could influence matter. How such an interaction could be exerted remains a contentious issue.
Kant[edit]
Main article: Immanuel Kant
For Kant (1724–1804) beyond mind and matter there exists a world ofa priori forms, which are seen as necessary preconditions for understanding. Some of these forms, space and time being examples, today seem to be pre-programmed in the brain.
Kant views the mind–body interaction as taking place through forces that may be of different kinds for mind and body.[42]
Huxley[edit]
Main article: Thomas Huxley
For Huxley (1825–1895) the conscious mind was a by-product of the brain that has no influence upon the brain, a so-called epiphenomenon.
Whitehead[edit]
Main article: Alfred North Whitehead
A. N. Whitehead advocated a sophisticated form of panpsychism that has been called by David Ray Griffin panexperientialism.[44]
Popper[edit]
Main article: Karl Popper
For Popper (1902–1994) there are three aspects of the mind–body problem: the worlds of mind, matter, and of the creations of the mind, such as mathematics. In his view, the third-world creations of the mind could be interpreted by the second-world mind and used to affect the first-world of matter. An example might be radio, an example of the interpretation of the third-world (Maxwell's electromagnetic theory) by the second-world mind to suggest modifications of the external first world.
Searle[edit]
Main article: John Searle
For Searle (b. 1932) the mind–body problem is a false dichotomy; that is, mind is a perfectly ordinary aspect of the brain. In some sense this is also the point of view of Aristotle[dubious ][citation needed], outlined above.

The restriction of causality to 'efficient causality' lead to the neglect of 'goal-orientation' since it was no longer necessary within [that] framework... Not considering 'goal-orientation' resulted in the neglect of 'embedment' and the consequential presupposition of 'isolation' with separation between brain, body, and environment. Neglecting 'embedment' lead to the equation of perception/action with sensory impression/movement which could be well accounted for by 'efficient causality'. Accordingly, since dominated by 'efficient causality', qualia and intentionality, as related to perception/action rather than to sensory impression/movement, were excluded from science and consequently regarded [as] purely philosophical problems. Analogous to 'final causes', 'formal causes' were eliminated as well... 'Efficient causality' is not compatible with 'embedded coding' [which] is necessarily tied with 'formal causality' and 'final causality'... Finally, the possibility of mental causation remains incompatible with 'efficient causality'. It can, however, be properly described by 'formal and final causality'.

Walter Freeman, with his usual originality, suggest that we may be looking at the whole thing in completely the wrong way when we ask whether consciousness causes or is caused by neural activity. He suggests that circular causation is a more relevant concept in this regard than linear causation. Consciousness and neural activity are certainly interdependent, but it is impossible in principle to say that either causes the other. Thus the whole concept of consciousness as agent is simply a misreading of the true situation.
Through my readings in physics and philosophy, I learned the concept of circular causality, which invokes hierarchical interactions of immense numbers of semiautonomous elements such as neurons, which form nonlinear systems. These exchanges lead to the formation of macroscopic population dynamics that shapes the pattern of activity of the contributing individuals...Circular causality departs so strongly from the classical tenets of necessity, invariance, and precise temporal order that the only reason to call it that is to satisfy the human habitual need for causes. The most subtle shift is the disappearance of agency, which is equivalent to loss of Aristotle's efficient cause...The very strong appeal of agency to explain events may come from the subjective experience of cause and effect that develops early in human life, before the acquisition of language...the question I raise here is whether brains share this property with other material objects in the world. The answer I propose is that assignment of cause and effect to one's self and to others having self-awareness is entirely appropriate, but that investing insensate objects with causation is comparable to investing them with teleology and soul. The further question is: Does it matter whether or not causality is assigned to objects? The answer is "Very much." Several examples are given of scientific errors attributed to thinking in terms of linear causality. The most important, with wide ramifications, is the assumption of universal determinacy, by which the causes of human behavior are limited to environmental and genetic factors, and the causal power of self-determination is excluded from scientific consideration. - ^ Eric R.

In what follows, we shall explore contemporary issues in the nature of consciousness itself, the fortunes of nonreductive materialism (specifically, functionalism) in the philosophy of mind, the neuronal basis of our moral knowledge, the future of our moral consciousness, the roles of science and religion in our public schools, the proper cognitive kinematics for the epistemology of the twenty-first century, the basic nature of intelligence, the proper semantic theory for the representational states of terrestrial brains generally, the fortunes of scientific realism, recent arguments against the identity theory of the mind–brain relation, the fundamental differences between digital computers and biological brains, the neuronal basis of our subjective color qualia, the existence of novel – indeed, 'impossible' – color qualia, and the resurrection of objective colors from mere 'secondary' properties to real and important features of physical surfaces. What unites these scattered concerns is, once more, that they are all addressed from the standpoint of the emerging discipline of cognitive neurobiology. The exercise, as a whole, is thus a test of that discipline's systematic relevance to a broad spectrum of traditional philosophical issues.

This book revises the traditional view of consciousness by claiming that Cartesianism and Descartes' dualism of mind and body should be replaced with theories from the realms of neuroscience, psychology and artificial intelligence. What people think of as the stream of consciousness is not a single, unified sequence, the author argues, but 'multiple drafts' of reality composed by a computer-like 'virtual machine'. Dennett considers how consciousness could have evolved in human beings and confronts the classic mysteries of consciousness: the nature of introspection, the self or ego and its relation to thoughts and sensations, and the level of consciousness of non-human creatures.

Combining ideas from philosophy, artificial intelligence, and neurobiology, Daniel Dennett leads the reader on a fascinating journey of inquiry, exploring such intriguing possibilities as: Can any of us really know what is going on in someone else's mind? What distinguishes the human mind from the minds of animals, especially those capable of complex behavior? If such animals, for instance, were magically given the power of language, would their communities evolve an intelligence as subtly discriminating as ours? Will robots, once they have been endowed with sensory systems like those that provide us with experience, ever exhibit the particular traits long thought to distinguish the human mind, including the ability to think about thinking? Dennett addresses these questions from an evolutionary perspective. Beginning with the macromolecules of DNA and RNA, the author shows how, step-by-step, animal life moved from the simple ability to respond to frequently recurring environmental conditions to much more powerful ways of beating the odds, ways of using patterns of past experience to predict the future in never-before-encountered situations.
