The document discusses various theories regarding the relationship between the mind and body/brain, including dualism, monism, idealism, materialism, and neutral monism. Dualism proposes that the mind and body are separate substances that interact, while monism argues they are different aspects of the same substance. Materialism specifically states that only matter exists and the mind can be explained physically. The debate examines ideas such as consciousness, cognition, intelligence and how to define the mind.
An understanding of various concepts applied in the relationship between the physical and mental and the implications these theories have on religion.
Philosophy of mind is a branch of philosophy that studies the nature of the mind, mental events, mental functions, mental properties, consciousness and their relationship to the physical body, particularly the brain. The mind–body problem, i.e. the relationship of the mind to the body, is commonly seen as one key issue in philosophy of mind, although there are other issues concerning the nature of the mind that do not involve its relation to the physical body, such as how consciousness is possible and the nature of particular mental states

CHAPTER 4The Nature of Substance, Reality, and Mind Idealism,.docxchristinemaritza
CHAPTER 4
The Nature of Substance, Reality, and Mind: Idealism, Dualism, and Materialism
There are a number of complex philosophical issues brought about by a discussion of substance. As you may recall from an earlier chapter, the Ancient Greeks were very much concerned about the question of substance. At present, science tells us everything is made up of material atoms, and yet, philosophers still debate this scientific conclusion. It is not to say that atoms do not exist (although no one has actually seen one, which is another question about scientific realism), but rather a question of what is reality made up of, mind, matter, or a combination of both.
These questions lead to other questions regarding the nature of the human mind. Is it just the brain or does it have an immaterial component? What of the soul? All these questions will be considered in the following sections below.
POWERFUL IDEAS: THE NATURE OF SUBSTANCE
Materialism claims that all real objects are physical. Dualism claims that all real objects are either physical or nonphysical. Idealism claims that all real objects are nonphysical.
Berkeley and Idealism
Berkeley contends that the only things that are real are ideas. This view is known as idealism. All the objects we encounter in the world (which is an idea as well) are nonmaterial objects. As bizarre as this may at first sound, what you should be aware of is the fact that the only objects that we do have direct access to in our mind (or brain) are ideas.
We assume that our idea of objects in the world is tied to or come from these objects; some underlying physical substance, yet Berkeley is denying that we have any good reason to infer to this material substance. Berkeley employs a radical empiricism. He thought that we can only acquire knowledge from our experiences—from our per- ceptions. What is the nature of our perceptions? We assume that we perceive objects directly, yet in fact, what we are doing is experience an idea of the object, which has been constructed by our mind. Berkeley goes on to argue that “to exist is to be perceived.”
Berkeley contends that the only things that are real are ideas. All the objects we encounter in the world—which is an idea as well—are nonmaterial objects. As bizarre as this may at first sound, what you should be aware of is the fact that the only objects that we do have direct access to are our ideas. We assume that our idea of objects in the world are tied to or come from those objects (we think those ideas correspond to object in reality), some underlying physical substance, yet Berkeley is denying that we have any good reason to infer to is this material substance.
He may have a point. Consider a strawberry, for example. It has a certain color, shape, and weight; it has a particular texture, taste, and smell. These are all perceptions, ideas in your mind. If you take away the taste of the strawberry, take away its smell, its weight, its shape—what do you have left? Nothing. The ...
What is a human soul? Assuming the soul exists, ‘when’ was it created and how does it interact with the body? Would a brain-damaged person be a soul-damaged person, too?
If a person’s brain were 100% replaced with electronical components, would s/he still be the same person? Can a machine be a person (as long as ‘on the outside’ it behaved like one)? Does a robot have ‘free-will’?

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

4. 4
INTELLIGENCE
• A measure of performance in solving problems?
• Are animals intelligent?
• Are plants intelligent?
• Are all humans intelligent the same way?
• Are intelligence values only zero and one?
• Are all living beings “intelligent”?
5. 5
COGNITION
• The set of cognitive faculties: memory, learning,
reasoning, ...
• What is a cognitive faculty?
• Are they independent?
• Are they all the same thing?
• Are all living beings “cognitive systems”?
• What else has cognitive faculties?
6. 6
MIND
• Does it correspond to all brain processes?
• Does it correspond to a subset of brain processes?
• Does it correspond to more than brain processes?
• Is it the same thing as cognition?
• Is it the same thing as consciousness?
• Is memory part of mind? Is seeing part of mind? Is
moving an arm part of mind? Is eating part of mind?
8. 8
The Takeover of the Mind
• Ancient Greeks: even rivers are sentient
• Why would we think that we are any better than rivers?
• Note: rivers live far longer than us
• Until 30 years ago: a person is dead if the “body” is dead
(heartbeat, breathing)
• Now: is a person dead if her brain is dead?
9. 9
The Takeover of the Mind
• Proof that the mind is a recent accident: we ask ourselves what
the mind is!
• When we ask what the mind is, we implicitly assume that the
body is a given.
• We don’t take the mind for granted and wonder what the body is
and why we have bodies.
• We are bodies that wonder about their minds, not minds that
wonder about their bodies.
10. 10
The Takeover of the Mind
• However, we use the body as a clue to find out who else has a
mind
• If I transplant the brain of a dog into the body of a human, can I
keep that human on a leash?
• May I keep a mentally disabled person on a leash?
11. 11
THE MIND-BODY DEBATE
• Is our mind made of matter?
• Is it made of a different substance?
• What differentiates the mental from the non-mental?
• How do our mind and our body relate?
• Is our mind inside our body?
• Is our mind born with the body?
• Will it die with the body?
• Does it grow with the body?
• What is the relationship between the mental and the
neural?
• How does the mental originate from the neural?
• What is in the mind?
12. 12
DUALISM
• Dualism: mind and body are made of two different
substances
– Substance dualism: the mind is a different
(nonphysical) substance altogether from the brain
• René Descartes (1649)
– A substance is characterized by that property
that it cannot lack and still be the same
substance (extension and “cogito”)
– "Res extensa" (things that have an extension)
and "res cogitans" (things that think) belong to
two separate realms, and cannot be studied with
the same tools
13. 13
DUALISM
• Substance Dualism/ Descartes
– Newton's Physics is a direct consequence of that approach:
Physics studies the realm of matter, and only deals with
matter.
– Aristotle's dualism: living and nonliving things
– Descartes: equivalence between living and nonliving matter
(animals are machines)
– There is "one" physical world for everything
– Emphasis on mind, not on life
– The brain is the seat of the body-mind interaction
14. 14
DUALISM
• Dualism
– David Hume’s “Bundle Dualism” (1740):
• The ultimate skeptic, who reduced matter, mind, religion,
and science to illusions/delusions
• Matter is a fiction (but a body does exist, whatever it may
be)
• The mind is a theater where perceptions play their part in
rapid succession (a “bundle” of perceptions)
• “I may venture to affirm of the rest of mankind that they
are nothing but a bundle or collections of different
perceptions “
16. 16
DUALISM
• Epiphenomenalism (Charles Bonnet - 1754)
– Mind and body do NOT quite interact
– The brain influences the mind, but the mind does not
influence the brain
– Mental events are caused by physical events in the brain, but
have no effects upon any physical event
– The mind merely observes the behavior of the body, although
it believes that it actually causes it.
– Donald Davidson's anomalous monism (1970)
– Jaegwon Kim’s supervenience (1984)
17. 17
DUALISM
• Property Dualism: the mind is the same substance as the
brain, but comes from a different class of properties (that are
exclusive of the brain).
– Charles Dunbar Broad (1925):
• The universe is inherently layered
• Each layer has its own properties
• Each layer yields the following layer but cannot
explain the new properties that emerge with it
• At each level some properties apply, but at the
immediately higher level some other properties apply
• Supervenience
18. 18
DUALISM
• Property Dualism
– John Searle's “biological naturalism” (1992)
• Brain processes cause mental states
• The mental state is an emerging property
• Mental states are nonphysical, but form a novel class
of features of the brain with properties (such as
meaning and awareness) that are different from those
of matter
• The relation between brain states and mental states is
causal, in both directions, each causing the other.
• The mind is material, but at the same time it cannot be
reduced to any other physical property
19. 19
DUALISM
• Supervenience/ examples
– Biological properties "supervene" (or "are supervenient")
on physical properties, because the biological properties
of a system are determined by its physical properties.
– Biological and physical properties of an organism are
different sets of properties, but the physical ones
determine the biological ones.
– Chemical compounds have density and conductivity,
whereas biological organisms have growth and
reproduction.
– Another example: electrons have mass and spin, but
electricity has potential and intensity
20. 20
DUALISM
• Supervenience/ Jaegwon Kim (1984)
• The mental supervenes on the neural
• Mind is to brain what lightning is to electrically
charged particles: the same phenomenon, that presents
itself in two different ways.
• One can organize nature in a hierarchy, starting with
elementary particles and ending with consciousness.
• At each level a new set of properties "emerge": the
weak force at the elementary particle level, viscosity
at the molecular level, metabolism at the biological
level, etc etc…
• and consciousness at the cognitive level.
21. 21
DUALISM
• Property Dualism/Supervenience
– David Chalmers (1996)
• "Logical" supervenience (loosely, "possibility")
is a variant of supervenience: some systems
could exist in another world (are "logically"
possible), but do not exist in our world (are
"naturally" impossible)
• Natural supervenience occurs when two sets
of properties are systematically and precisely
correlated in the natural world
• Logical supervenience implies natural
supervenience, but not viceversa.
22. 22
DUALISM
• Property Dualism/Supervenience
– David Chalmers (1996)
• There may be worlds in which two properties
are not related the way they are in our world,
and therefore two naturally supervenient
systems may not be logically supervenient.
• Most facts supervene logically on the physical
facts: if they are identical physical systems,
then they are identical, period
• Exception: consciousness is not logically
supervenient on the physical.
• Consciousness "cannot" be explained by the
physical sciences by reducing the system to
ever smaller parts.
23. 23
DUALISM
• Trialism: another way to explain how mind and body interact
– Karl Popper's and John Eccles' world of ideas (1977)
• The world of ideas evolves through the growth of
objective knowledge. The growth and evolution of
objective knowledge obey Darwinian laws
• The interaction between the mind and the brain of an
individual is analogous to a probability field of Quantum
Mechanics ("psychon" is the mental unit that transmits
mental intentions to the neural units)
24. 24
DUALISM
• Trialism
– Rudy Rucker’s mindscape (1982)
• Evidence that there exists a world of ideas separate from
the mental and the physical: “is what you thought
yesterday still part of your mind?”
• Our minds can travel the mindscape that contains all
possible thoughts just like our bodies can travel the
physical space that contains all possible locations.
• Minds share the same mindscape the way bodies share the
same physical space.
25. 25
DUALISM
• Trialism
– Roger Penrose’s protoconsciousness (1989)
• “Protoconscious" information is encoded in space-time
geometry at the fundamental Planck scale
• The mind has access to them (i.e., is conscious) when a
particular quantum process occurs in our brain
26. 26
INTENTIONALITY
• What is really unique about Mind? Descartes: res cogitans
• Mental states have the property of referring to something
else
27. 27
INTENTIONALITY
• Intendo = refer to
• Intentionality = the property of being “about” something
• The mental is intentional
• Intentionality comes in different "flavors", "propositional
attitudes": hope, belief, desire, know
28. 28
INTENTIONALITY
• Franz Brentano (1874): the “irreducibility thesis”
– All mental phenomena are intentional
– No physical phenomenon is intentional
– Therefore mental phenomena cannot be reduced
to physical phenomena
– The mental and the physical are different
substances
• Alexius Meinong (1904): mental states must have
their own existence apart from the physical world
• Brentano: all mental states are "representations" of
objects
• Meinong: those representations exist apart from the
objects they represent
29. 29
MONISM
• Monism: only one substance exists
– Materialism: only matter exists
– Idealism: only mind exists

MONISM
• Monism
– Baruch Spinoza (17th century): only God exists
• Only one substance exists, that is infinite and eternal, and
“the” substance has two properties: it is conscious and it
has extension.
• This substance is expressed in an infinite series of
“modes”.
• Humans only perceive two of those modes because we
are equipped with only two attributes of that substance,
hence we see a world of minds and bodies
• When we perceive modes through the attribute of
thought, we perceive ideas, and we perceive them
through the attribute of extension, we perceive objects
• God is all that exists (he is what is), there is nothing that
is not God (“pantheism”)
• Spinoza got rid of the mind
31. 31
IDEALISM
• Idealism: only mind exists
– Gottfried Leibniz (17th c)
• Only minds exist
• Humans are not the only ones to have minds.
• Everything has a mind ("panpsychism”)
• Minds come in degrees, starting with matter (whose
minds are very simple) and ending with God (whose
mind is infinite)
• Reality is the set of all finite minds (or "monads")
that God has created
• How to solve the mind-body problem: get rid of the
body
32. 32
IDEALISM
• Idealism
– George Berkeley (18th c)
• All we know is our perceptions ("esse est percipi")
• The only thing that exists is the experiences of our
mind
– Alfred Whitehead (1920)
• Mental life occurs in a field of protoconscious
events
34. 34
MONISM
• Neutral Monism
– Ernst Mach (1886): there is a fundamental constituent of the
universe which is neither mental nor physical but yields both
the mental and the physical that we observe.
– William James (1904): “The instant field of the present is at
all times what I call the ‘pure’ experience. It is only virtually
or potentially either object or subject as yet.”
35. 35
MONISM
• Neutral Monism
– Bertrand Russell (1921)
• Only spacetime events exist
• Everything in the universe is made of spacetime events
which are neither mental nor physical.
• Both matter and mind are meaningless over-
simplifications of reality (different ways of organizing
space-time)
• Matter and mind are both built out of the same stuff,
which is neither material not mental ("neutral")
38. 38
MONISM
“To do is to be - Descartes
To be is to do - Voltaire
Do be do be do - Frank Sinatra”
(Men’s Restrooms, Greasewood Flats, Scottsdale)
39. 39
MATERIALISM
• Monism: only one substance exists
– Materialism
• Only matter exists
• The mind is as material as the body
• Consciousness is a physical processes in the
brain
• The mental can be explained from the physical
• Julien La Mettrie (1748): the mind as a machine
made of matter, and thought as a material
process (the "homme machine”)
• Herbert Feigl ("The Mental and the Physical",
1958) resurrects the mind-body problem for
20th century philosophy
40. 40
MATERIALISM
– Materialism
• 20th century: the mind-body problem became the
"mind-brain problem“
• (Note: too much emphasis on the brain now? I feel
pain in my foot, not in my brain!)
41. 41
MATERIALISM
– Materialism
• Identity theory (Ullin Place, John Smart - 1950s)
– Mental events are physical processes in the brain,
just like lightning is a physical process in the air.
– Mental states are identical to physical states of the
brain (“physicalism”)
– No need to explain how they interact: they are the
same thing
– Mental terms and physical terms are different
descriptions of the same states
– A desire, for example, is both a conscious and
physical state that causes some actions that are
both conscious and physical states.
– Feigl: mental states and physical states have the
same “extension” but different “intension”
42. 42
MATERIALISM
– Materialism
• Anomalous Monism (Donald Davidson, 1970)
– Simple syllogism:
• At least some mental events interact causally
with physical events
• Events related as cause and effect normally
fall under strict deterministic laws
• But there are no strict deterministic laws
under which mental events can be predicted
and explained (this is the "anomalism" of the
mind).
• This is a contradiction, unless the mind is
something else.
• The physical and the mental realms must
have essential features that are mutually
incompatible
43. 43
MATERIALISM
– Materialism
• Anomalous Monism
– There can be no laws connecting the mental with
the physical.
– There can be no theory connecting Psychology
and Neurophysiology.
– The language of Psychology cannot be reduced
to the language of Physics.
– There exist no "psychophysical" laws
– The mental domain cannot be the object of
scientific investigation
44. 44
MATERIALISM
– Materialism
• Token identity theory (Davidson, Jerry Fodor,
Hilary Putnam)
– Every mental state is identical to a physical state,
but the physical state corresponding to a given
mental state is not necessarily always the same
one
– People with widely different brains can be in the
same psychological state
– Different software programs can implement the
same function
45. 45
MATERIALISM
– Materialism/ Issues
• Leibniz's law“: two things are identical if and only if
all the properties that apply to the first one also
apply to the second, and viceversa
• Reducibility: how can feelings arise from material
processes? how can electrochemical activities in my
brain suddenly turn into the feeling of pain or fear?
• John Searle’s paradox: either the identity theory
leaves out the mind, in which case it is implausible,
or it does not, in which case it is not materialist
anymore.
46. 46
MATERIALISM
– Against physicalism
• The knowledge argument (Frank Jackson - 1982)
– A scientist who has a complete understanding of
the science of color, but has never experienced
color: will she learn something new the first time
that she experiences color?
– If yes, then there cannot be a complete physical
explanation of mental states.
• The philosophical zombie argument (Saul Kripke,
1972)
– If a world in which all physical facts are the same
as those of the real world must contain
everything that exists in the real world, then
– A world of non-conscious (zombie) human
beings identical to the real world of conscious
human beings must contain consciousness.
47. 47
MATERIALISM
– Beyond physicalism
• Bertrand Russell (1927)
– We cannot know the nature of matter other than
through theories and experiments
– In particular, we cannot know the processes that
occur in our own brain
– Mind allows us to perceive some of those brain
processes
– What a neurologist really sees while examining
someone else’s brain is a part of her own (the
neurologist’s) brain.
48. 48
MATERIALISM
– Beyond physicalism
• Bertrand Russell
– Consciousness gives us immediate, direct
knowledge of what is in the brain, whereas the
senses can observe (possibly aided by
instruments) what is in the brain.
– The mental is a transparent grasp of the intrinsic
character of the brain
– Consciousness is just another sense, a sense that,
instead of perceiving colors or smells or sounds,
perceives the very nature of the brain
49. 49
BEHAVIORISM
• Behaviorism
– Behaviorism deals with mental terms only to
the extent that they are related to behavior
– Behaviorism is not interested in discussing the
mind, only behavior and disposition to
behavior.
– Behaviorism rejects the common-sense notion
that our mental states cause behavior
– John Watson (1913)
• Mental states are unscientific
• All behavior can be explained as stimulus
and response relations.
50. 50
BEHAVIORISM
• Behaviorism
– Gilbert Ryle (1949):
• Descartes invented a myth: the myth of the mind
inside the body (“the ghost in the machine”)
• The mind is not a different substance but simply a
domain of discourse
• The mind "is" the behavior of the body.
• Physical objects exist, mental objects are merely
vocabulary.
51. 51
BEHAVIORISM
• Eliminative Materialism
– Wilfred Sellars (1956): the mental
vocabulary of “folk psychology” constitutes
a theory, that has not progressed for
millennia, that mostly fails to explain and
predict behavior, and that is founded on
knowledge about human beings that has
long been proven false
– Eliminative materialism (Paul Feyerabend -
1963, Richard Rorty -1965)
• Mental states (beliefs, hopes, etc) do not
exist
52. 52
BEHAVIORISM
• Eliminative Materialism
– Paul Churchland (1984)
• Our introspection cannot be trusted as our
other senses mislead us about the real
structure of the universe (we don’t see/ hear
elementary particles and probability waves)
• We explain people's behavior by using terms
that ascribe mental states to people
• There is nothing in the brain that resembles
what folk psychology talks about: there are
only patterns of neural activity
• We should replace the outdated language of
folk psychology with the language of
neurobiology, just like folk physics was
replaced by Newton's physics
53. 53
FUNCTIONALISM
• Functionalism (David Malet Armstrong, David Lewis -
1960s): the function not the substance
– If a mental state can be realized in more than one
physical state, is the physical state important at all?
– What is it that makes a physical state of the brain also a
mental state? the function it performs (eg, thermometer)
– Mental states have a function
– A mind doesn’t necessarily require a brain
– How do mental states cause physical behavior?
54. 54
FUNCTIONALISM
– Computational Functionalism (Hilary Putnam -
1960)
• If there is no correlation between mental and
physical states, why not classify mental states
based on their function, i.e. their causal roles
within the mental system, regardless of their
physical structure?
55. 55
FUNCTIONALISM
– Computational Functionalism
• Hilary Putnam
– The psychological state of an individual
can be identified with the state of a
“Turing machine”
– A psychological state causes other
psychological states according to the
machine's operations
– Belief and desire correspond to formulas
stored in two registers of the machine.
– Appropriate algorithms can process those
contents to produce action.
56. 56
FUNCTIONALISM
– Computational Functionalism
• Representational Theory of the Mind (Jerry
Fodor - 1975, Stephen Stich)
– Knowledge of the world is embedded in
mental representations
– Mental representations are symbols (the
“language of thought” or “mentalese”)
– Symbols can be “computed”
– The mind is endowed with a set of rules
to operate on such representations, i.e.
to “compute” the symbols
– Cognitive life is the output of those
rules
57. 57
FUNCTIONALISM
– Computational Functionalism/ RTM
• Mental states are computational states
• The mind processes symbols without knowing what
those symbols mean, in a purely syntactic fashion.
• Behavior is due only to the internal syntactic
structures of the mind.
• The mind is the software and the brain is its
hardware
• The execution of that program (the mind) in that
hardware (brain, computer,…) yields behavior
58. 58
FUNCTIONALISM
– Computational Functionalism/
RTM
• How mind and body
communicate: beliefs and
desires are information,
represented by symbols,
and symbols are physical
states of a processor, and
the processor is connected
to the muscles of the body.

59. 59
FUNCTIONALISM
– Computational Functionalism/ RTM
• The language of thought is an intrinsic part of the
brain and has somehow been produced through
evolution
• That language is shared by all creatures capable of
“propositional attitudes” (beliefs, hopes, fears,
desires)
• Note: “mind” is a purely syntactic program
60. 60
FUNCTIONALISM
– Computational Functionalism/ RTM
• Noam Chomsky in linguistics 91957) and
David Marr in vision (1982): the mind as a set
of modules that “compute” something based on
an innate symbolic capability.
• Noam Chomsky: "mental organs“ in addition to
physical organs.
• The mind is made of genetically-specified
modules, each one specialized in performing
one task.
• A module corresponds to a physical region of
the brain
• Modules communicate in the "language of
thought"
61. 61
FUNCTIONALISM
– Computational Functionalism
– Ned Block’s critique (1978)
• “Qualia”: sensations that are associated to the fact of
being in a given psychological state
• Inverted qualia: an organism whose functional states
are identical to ours, but in which pain causes the
sensation that we associate to pleasure
• Absent qualia: an organism whose functional states
are identical to ours, but in which pain causes no
sensation
• Functionalism cannot account for inverted and
absent qualia
• A functionalist might think that even Bolivia's
economy has mental states
62. 62
FUNCTIONALISM
– Computational Functionalism
• Homuncular Functionalism (Daniel Dennett - 1978,
William Lycan - 1987)
– A mental process is the product of many
independent lower mental processes, and each of
these lower processes is the product of more and
more primitive (less and less mental)
independent processes all the way down to the
physical processes of the brain
– Eventually this reductionist process reaches a
level at which problems can be solved with no
more intelligence than the one that can be found
in a neuron
63. 63
FUNCTIONALISM
– Homuncular Functionalism (Daniel
Dennett - 1978, William Lycan - 1987)
• Between the low level of
electrochemical processes and the
high level of psycho-functional
processes, nature is organized in a
number of hierarchical levels
(subatomic, atomic, molecular,
cellular, biological, psychological)
• Each level is both physical and
functional: physical with respect to its
immediately higher level and
functional with respect to its
immediately lower level
Psychological
Biological
Cellular
Molecular
Atomic
Subatomic
Physical
Functional
64. 64
FUNCTIONALISM
– Homuncular functionalism (Daniel Dennett -
1978, William Lycan - 1987)
• Proceeding from lower levels to higher levels
we obtain a physical, structural, description of
nature (atoms make molecules that make cells
that make organs that make bodies...).
• Proceeding backwards, we obtain a functional
description (the behavior of something is
explained by the behavior of its parts).
• The “aggregative ontology” ("bottom-up") and
the “structured epistemology” ("top-down") of
nature are dual aspects of the same thing.
• The apparent irreducibility of the mental is due
to the irreducibility of the various levels.
65. 65
• Homuncular functionalism
– Marvin Minsky (1988): Intelligent behavior
is due to the non-intelligent behavior of a
very high number of agents organized in a
bureaucratic hierarchy, the “society of the
mind”.
HOMUNCULAR FUNCTIONALISM

INTENTIONALITY REVISED
• Jerry Fodor:
– The mental is intentional, but it can be
reduced to the physical
• Fred Dretske:
– Intentionality is a general property of
systems
• Daniel Dennett:
– Nothing is intentional
• John Searle:
– Everything that is intentional is either
conscious or potentially conscious
68. 68
INTENTIONALITY REVISED
• Fred Dretske (1980):
– Intentionality is a general property of systems
– Any device that carries information exhibits
some degree of intentionality
– Intentionality is not unique of mental states, but
quite ubiquitous in living and even non-living
systems
– Just about everything in nature refers to
information that is available in the environment
– Having content is then not unique to the human
mind at all.
AGE TEMP.
69. 69
INTENTIONALITY REVISED
• Daniel Dennett (1987):
– In order to explain and predict the behavior
of a system one can employ 3 strategies:
• a "physical stance", which infers the
behavior from the physical structure
• a "design stance", which infers the
behavior from the function/purpose for
which it was designed
• an "intentional stance", which infers the
behavior from the beliefs/desires that
the system must exhibit to be rational
– These are simply three different ways of
speaking about the same thing
– We can ascribe a mind to anything
The tree needs water

70. 70
PHENOMENOLOGY
• Edmund Husserl (1900)
– Consciousness is intentional: consciousness is
“consciousness of” (“intentional” as in “refers to”)
– Intentionality links mind and phenomena, therefore
phenomena and being are the same thing
– The essence of something is not its physical
constituents or physical laws, but the way we
experience it
71. 71
PHENOMENOLOGY
• Edmund Husserl (1900)
– By separating phenomenon and being, science
denied humans the truth of the reality that they
experience
– ”Phenomenology” is the science of phenomena,
a return to the primary experience of the world
– The essence of the phenomenon is the sum of
all possible “intuitive” ways of knowing the
phenomenon
– This has to be achieve after “bracketing out”
the physical description of the phenomenon,
I.e. the description given by science
72. 72
PHENOMENOLOGY
• Martin Heidegger (1927):
– You can’t divide reality into subjective and
objective
– The objective is impossible because we are part of it
– We can’t be objective observers
– We don't exist as independent observers, we exist as
part of the world
– We react by instinct, we are thrown into the world
– We are rarely aware of what we are doing
73. 73
PHENOMENOLOGY
• Martin Heidegger (1927):
– Unity of the "dasein" (being)
– The distinction between mind and world is illusory:
there is only a “being in the world” that is not divided
into mind and world
– “Physical reality" and "mental life“ are meaningless
expressions: the world and the mind cannot be
separated
74. 74
PHENOMENOLOGY
• Phenomenal Externalism (Fred Dretske - 1996, Andy
Clark & David Chalmers - 1998)
– The mind extends to include whatever tools are used
– My mind spreads to the tools that i use in order to carry
out my cognitive processes
76. 76
BRAINS CAUSE MINDS
• IS THE BRAIN SUFFICIENT?
– Does a dead brain cause a mind?
– Does a brain removed from the body cause a mind?
– We are not aware of any mind that does not have a
body.
– Rephrase as SOME BODIES CAUSE MINDS
• IS THE BRAIN NECESSARY?
– We have no way of knowing if non-brain things cause a
mind
– Rephrase as AT LEAST SOME BODIES CAUSE
MINDS
77. 77
BRAINS CAUSE MINDS
• WHAT IS A BRAIN?
– Where are the borders of the brain?
– How much can we cut off a brain?
– Is the nervous system of an insect a brain?
– What makes something qualify as a brain?
