A pupil from whom nothing is ever demanded which
he cannot do, never does all he can. It is, no
doubt, a very laudable effort, in modern
teaching, to render as much as possible of what
the young are required to learn, easy and
interesting to them.  But when this principle is
pushed to the length of not requiring them, to
learn anything but what has been made easy and
interesting, one of the chief objectives of
education is sacrificed.                J. S.
Mill, Autobiography

The Metaphysical View Idealism Platos
Theory of Forms (a refutation of Materialism)
4
Idealism Platos Theory of Forms
  • The view that reality is primarily composed of
    ideas or thought rather than a material world is
    the doctrine known as Idealism. That is, an
    Idealist would say that a world of material
    objects containing no thought either could not
    exist or at the least would not be fully "real."
  • The earliest formulation of this view is given to
    us by Plato.
  • In Platos Allegory of the Cave, the world of
    shadows is representative of the material world
    and is not fully real.

5
Platos Theory of Forms
  • What is the problem with which Plato is faced?
  • How can one live a happy and satisfying life in a
    contingent, changing world without there being
    some permanence on which one can rely? (The
    Ethical Problem)
  • Indeed, how can the world appear to be both
    permanent and changing all the time. (The
    Metaphysical Problem)
  • Plato observed that the world of the mind, the
    world of ideas, seems relatively unchanging.
    Justice, for example, does not seem to change
    from day to day, year to year.
  • On the other hand, the world of our perceptions
    change continuously. One rock is small, the next
    large, the next?

6
Platos Theory of Forms
  • To resolve this problem, Plato formalized the
    classic view of idealism in his doctrine of
    Forms.
  • In everyday language, a form is how we recognize
    what something is and unify our knowledge of
    objects. (e.g How do we say two objects of
    different size, color, etc. are both cars?)
  • Permanence comes from the world of forms or ideas
    with which we have access through reason.
  • In Platos view, all the particular entities we
    see as material objects are shadows of that
    reality. Behind each entity is a perfect form or
    ideal. Ideal forms are eternal and everlasting.
    Individual beings are imperfect.
  • e.g. Roundness is an ideal or form existing in a
    world different from physical basketballs.
    Individual basketballs participate or copy the
    form.

7
Platos Theory of Forms
  • Forms are transcendent, that is they do not exist
    in space and time. That is why they are
    unchanging.
  • Forms are pure. They only represent a single
    character and are the perfect model of that
    property.
  • Material objects are a complex conglomeration of
    copies of multiple forms located in space and
    time.
  • Forms are the cause of all that exists in the
    world.

8
What is the Essence of the Form of the Good?
  • Forms are the cause of all that exists in the
    world. Forms exist in a hierarchy with the Form
    of The Good being the highest form and thus is
    the first cause of all that exists.
  • Forms are the ultimate reality because they are
    more objective than material things which are
    subjective and vary in our perception of them.
  • For Socrates and Plato, the question What is a
    thing? is the question what is the essence of
    the thing? That is, the attempt is to identify
    what (presumably one) characteristic or property
    makes that thing what it is.

9
What is the Essence of the Form of the Good?
  • Further, Plato compares the power of the Good to
    the power of the sun. The sun illuminates things
    and makes them visible to the eye. The absolute
    or perfect Good illuminates the things of the
    mind (forms) and makes them intelligible.
  • The Good sheds light on ideas but, the vision of
    the idea of the Good is, according to Plato, too
    much for human minds.
  • When Plato emphasizes The Good as the cause (I.e.
    an active agent) of essences, structures, and
    forms, as well as of knowledge, he seems to be
    invoking the idea of the Good as God. The Good as
    absolute order makes all intermediate forms or
    structures possible.

10
Towards A Modern View Cartesian Dualism
11
Descartes Modern Philosophy
René Descartes (15961650) was a creative
mathematician of the first order, an important
scientific thinker, and an original
metaphysician. He offered a new vision of the
natural world that continues to shape our thought
today a world of matter possessing a few
fundamental properties and interacting according
to a few universal laws. This natural world
included an immaterial mind that, in human
beings, was directly related to the brain. In
many ways, Descartes established Philosophy as a
modern endeavor and saw science and philosophy as
intricately linked in their pursuit of knowledge.

12
Yet, Descartes embraced the Sientific Revolution
fundamentally differently that Galileo.
Descartes claimed to possess a special method,
which was variously exhibited in mathematics,
natural philosophy, and metaphysics, and which,
in the latter part of his life, included, or was
supplemented by, a method of doubt. He was still
fundamentally too much of a Rationalist in the
traditions of Plato. This method of conducting
science is quite contrary to the approach that
was gaining sway with Galileo. Galileo proposed a
methodology which did not first engage in a
metaphysical search for first principles on which
to base his science.
13
(No Transcript)
14
For Descartes, Galileo erred by without having
considered the first causes of nature, he has
merely looked for the explanations of a few
particular effects, and he has thereby built
without foundations But ultimately, it was
Galileo (not Descartes) that pushed the
Scientific Revolution forward.
15
Galileo The Scientific Revolution Galileo
Galilei (1564  1642), was an Italian physicist,
mathematician, astronomer, and philosopher who
played a major role in the Scientific Revolution.
Galileo has been called the "father of modern
observational astronomy", the "father of modern
physics", the "father of science", and "the
Father of Modern Science Galileo proposes that
physics should be a new science based on
methods of observation not just on the methods of
reason. Thus, Galileo discovered many things
with his telescope, he first saw the moons of
Jupiter and the mountains on the Moon he
determined the parabolic path of projectiles and
calculated the law of free fall on the basis of
experiment.
16
Galileo The Scientific Revolution He is known
for defending and making popular the Copernican
system, using the telescope to examine the
heavens, inventing the microscope, dropping
stones from towers and masts, playing with
pendula and clocks, being the first real
experimental scientist, advocating the relativity
of motion, and creating a mathematical physics.
His major claim to fame probably comes from his
trial by the Catholic Inquisition and his
purported role as heroic rational, modern man in
the subsequent history of the warfare between
science and religion. In 1636, a Hobbes travels
to Italy where he may have met with Galileo. With
the influence of Galileo, Hobbes develops his
social philosophy on principles of geometry and
natural science.
17
Materialism
  • Thomas Hobbes (1588-1679) rejects Cartesian
    dualism claiming that Descartes Mind/Body problem
    itself refutes dualism.
  • Since mind and body cannot interact, they cannot
    both exist within human nature.
  • There can only be one realm of human nature and
    that is the material world.
  • All human activities, including the mental, can
    be explained on the paradigm of a machine.

18
Materialism
  • Hobbes was reductionist in that he believed that
    one kind of purported reality (the mind) could be
    understood entirely in terms of another (matter).
  • New scientific techniques of observation and
    measurement being used by Galileo, Kepler, and
    Copernicus were making giant strides in
    understanding the universe.
  • The spirit of his century suggested to Hobbes
    that all reality would be explained in time in
    terms only of the observable and the measurable.
  • Hobbes himself was unable to explain any mental
    processes in terms of the physical.
  • Perhaps motivating Hobbes view was basically his
    passionate faith in the advancement of science at
    the time.

19
The Prima Facie (or Self-evident) Case for
Materialism
  • The argument from common sense
  • If there are other realities besides the
    material, can they causally interact with the
    material world?
  • If so, how can this interaction happen? If they
    can not interact, what does it mean to say that
    such a reality exists?
  • Please note this may be more difficult that even
    the mind/body problem where we do seem to have
    direct evidence to believe that our own
    consciousness exists.

20
The Prima Facie (or Self-evident) Case for
Materialism
  • The argument from science
  • Science seems to be our most developed and useful
    organized body of knowledge about the world by
    focusing on observation and measurement of the
    physical material world. In the history of
    science, discussion of any kinds of entities
    other than material entities largely have been
    blind alleys.
  • The history of science is full of examples where
    entities once thought to be necessary to explain
    life and man have been replaced by fully causal
    explanations in terms of chemicals and biological
    processes. Doesnt it seem reasonable that this
    also may be the case with mental states? (458)

21
Modern Idealism
  • The founder of modern Idealism is Bishop George
    Berkeley (1685-1753).
  • Berkeley argued against Hobbes Materialism that
    the conscious mind and its ideas and perceptions
    are the basic reality.
  • Berkeley believed that the world we perceive does
    exist. However that world is not external to and
    independent of the mind.
  • The external world is derived from the mind.
  • However, there is a further reality beyond our
    own minds. Since we have ordered perceptions of
    the world which are not controlled by an
    individuals mind, they must be produced by Gods
    divine mind.
  • (900)

22
Pragmatism
  • The major pragmatist philosophers are Charles S.
    Pierce (1839-1914) and William James (1842-1910).
  • To the American Pragmatists, the debate between
    materialism and idealism had become a pointless
    philosophical exercise.
  • They wanted philosophy to get real (as we might
    say today.)
  • The Pragmatists argued that philosophy loses its
    way when it loses sight of the social problems of
    its day. Thus, the Pragmatists focused on issues
    of practical consequence. For them, asking even
    what is real in the complete sense is not an
    abstract matter.

23
Pragmatism
  • In terms of Metaphysics, James argued against
    both sense observation and scientific method and
    reason as the determinants of reality.
  • Reality is determined by its relation to our
    emotional and active life. In that sense, a man
    determines his own reality. What is real is what
    works for us.
  • Pragmatism was refreshing and offered new
    insights to various disciplines, particularly
    psychology as a developing science.
  • Ultimately to most philosophers, pragmatism
    failed to give a systematic response to the
    traditional philosophical issues that Materialism
    and Idealism were struggling with.

24
Logical Positivism
  • Similar somewhat to the American Pragmatists, the
    Logical Positivists also viewed the debate
    between materialism and idealism as a pointless
    philosophical exercise.
  • Unlike the Pragmatists however, they identified
    the problem with the metaphysical debate as a
    problem in understanding language and meaning.
  • The Logical Positivists proclaimed that
    Metaphysics was meaningless and both Materialists
    and Idealists were making claims that amounted to
    nonsense. They might be proposing theories that
    seemed to be different but had no consequences to
    our understanding of the world.
  • A.J. Ayer (1910 1989) proposed a criterion by
    which it could be determined what was a
    meaningful statement to make about reality.

25
The Logical Positivist Criteria of Meaning
  • Metaphysical statements such as God exists or
    Man has a mind and body or ethical statements
    such as Lying is wrong are meaningless for
    Ayer.
  • Such statements do not make assertions about the
    world, but in fact only express emotions and
    feelings like poetry.
  • A statement can only be meaningful if it is
    verifiable by means of shared experience.

26
Anti-Realism
  • Anti-realism rejects the notion that there is a
    single reality. Rather, there is multiple
    realities that are dependent upon how they are
    described, perceived, or thought about.
  • Notice that whereas Berkeley emphasized
    consciousness as the basis of the world, the
    modern anti-realists focus on the pervasiveness
    of language.
  • Is Realism a condition of sanity? Can it be
    challenged?
  • How can you even know about reality without
    language? Thus, what sense does it make to say
    reality exists beyond language?
  • Is reality dependent on our contextualization
    of things. Does this mean reality is just
    whatever you think it is? Is this different than
    subjectivity? Or is it an objective, shareable
    cultural phenomena?

27
The Problem of Free Will
The Prima Facie (or Self-evident) Case for Free
Will
  • From common sense
  • I have a direct consciousness of being able to do
    otherwise.
  • I have a direct consciousness of causing my own
    behavior.
  • I accept responsibility for my decisions.

28
The Prima Facie (or Self-evident) Case for
Determinism
  • From common sense
  • Everything appears to have a scientific cause.
  • It is not understood by what mechanism a mental
    state such as a will or an intention can cause
    behavior in the physical world.
  • We seem to be think it quite appropriate to
    explain the behavior of others (and they us)
    simply in terms of behavior or reasons that they
    are unaware of, even when the person themselves
    would have said they chose to do so.

29
Determinism
  • Determinists argue that previous events and the
    laws of nature cause all human acts.
  • Human acts are predictable theoretically if we
    knew all prior conditions and the laws governing
    those conditions on the model of physics.
  • Sir Isaac Newton (1642 1727) argued that all
    bodies in the universe both the smallest atoms
    and the largest planets act in accordance with
    the universal laws of nature.

30
Determinism
  • The Marquis de LaPlace (1749-1827) applied the
    Newtonian conception and argued that humanity is
    part of a causal chain, as is all phenomena.
  • For LaPlace, free will is an illusion that we
    have since we are ignorant of the appropriate
    laws of human nature.
  • John Hospers (1918 - ) argues that the
    unconscious motivations for behaviors discovered
    by Sigmund Freud determine all human action.
  • Subsequently in the view of hard line
    determinists, humans are not responsible for
    their acts.

31
Libertarianism
  • Libertarianism is the view that our choices are
    not determined by the laws of nature. It is often
    referred to as indeterminism.
  • One prevalent view of libertarianism is John Paul
    Sartres existentialism. Sartre claims that
    humans can be motivated by a future state, not a
    past state.
  • Thus, we can conceive and choose what is not,
    i.e. negativity or non-being. (that is, what does
    not yet exist). To be determined would mean that
    what is past or present could determine the
    future (what does not exist.)
  • Although man is radically free, most forms of
    existentialism allow that man can also choose to
    sell out his freedom and act as if he is
    determined by desires and emotions. Yet, man is
    always responsible for his actions.

32
Compatibilism
  • Compatibilism argues that free will can be made
    compatible with determinism.
  • The general strategy of compatibilism is
    typically to re-define freedom.
  • Thomas Hobbes said that freedom was only the
    absence of physical restraints and causal
    determinants do not act as physical restraints.
  • Although classical compatibilist views such as
    Hobbes appeal to our need to explain the paradox
    of free will and determinism, most philosophers
    find it unconvincing and ignores the real issue
    that cannot be defined away.

33
Chapter 4 Philosophy and God (a Metaphysical
Study)
34
Does God Exist?
  • Theism is the belief in a personal God who is
    creator of the world and present in its processes
    and who is actively engaged in the affairs of
    humans.
  • Pantheism is the belief that God is the universe
    and its phenomena (taken or conceived of as a
    whole). God exists but is not personally involved
    in the lives of men.
  • Atheism is the denial of Theism. (Metaphysical
    View) It states that there is no God.
  • Agnosticism is the view that it cannot be known
    whether God exists or not. (Epistemological
    View)
  • According to Logical Positivism, the question
    Does God Exist? is meaningless.

35
First, Can We Even Make Sense of the Question?
  • Surely before trying to answer the question, one
    needs to ask the following questions
  • What does one mean by the word or concept of
    God?
  • What is the sense of existence that is being
    asserted when one says God exists.
  • Without being clear about these issues, the
    argument often becomes mostly subjective.

36
What Do We Mean by God?
  • If we say that God is the creator of the
    universe, do we mean
  • 1) that there is a Being that is God that could
    or could not be the one who created the universe,
    but as a matter of fact is the creator of the
    universe? Or
  • 2) that by definition that God is the Being that
    created the universe such that it would be a
    logical error to say that God did not create the
    universe.
  • Note that if we mean the first, we have still not
    said who (or what) God is, apart from what he has
    done.
  • If we mean the second, of course given the
    inherent assumptions, then God exists. But we
    have committed the logical fallacy of begging
    the question.

37
What is the Meaning of Existence that is Being
Used to Say that God Exists?
  • Is existence a property of an entity? I say This
    chair is black. Blackness is a property of the
    chair. So that I would say that this chair has
    the property of existing and thus there could
    be chairs some of which have the property and
    some dont. Then would I say that some chairs
    exist and some do not like I would say some
    chairs are black and some are not?
  • Or is existence of the chair identified in terms
    of its relationship to a real world, say Hobbes
    material world or Berkeleys mental world? But
    then what sense does it make to say that Gods
    existence is dependent upon a world that He
    created and itself came into existence after
    Him?
  • If not, then what is this form of existence for
    God that we are asserting?

38
Is it Possible to Talk About Something that Does
Not Exist?
  • We generally believe that only things that exist
    can have properties. Thus, by referring to God
    with properties, I.e. omnipotent, do we prove
    that God exists?
  • Probably not of course. We do refer to Santa
    Claus as having a white beard and living at
    the North Pole. And then turn around and say
    Santa does not exist.
  • Bertrand Russell proposed a Theory of
    Descriptions to account for how we refer to
    things that appear to have properties or
    characteristics but may or may not exist.

39
How is it Possible to Talk About Something that
Does Not Exist?
  • Russells solution is to take names to be
    shorthand for descriptions. For example, Santa
    Claus is a person who goes by the description
    that he lives on North Pole, and delivers toys to
    kids for Christmas, and the sentence Santa
    doesnt exist should be understood as There is
    no X, such that X is a person that lives on North
    Pole, etc., etc.
  • Thus, presumably for Russell to say God does not
    exist would be to say There is no Being, such
    that the Being existed prior to the creation of
    the universe, and then created the universe,
    etc., etc.

40
So, is Logical Positivism right after all?
  • Theism is so confused and the sentences in which
    'God' appears so incoherent and so incapable of
    verifiability or falsifiability that to speak of
    belief or unbelief, faith or unfaith, is
    logically impossible.
  • A. J. Ayer, Language, Truth, and Logic
  • Wikipedia suggests A. J. Ayer (1910-1989) was an
    atheist. Ayers position on the existence of God
    should not be confused with atheism. Of course,
    claiming that God does not exist also lacks
    analytic or empirical verifiability and is thus
    also meaningless.
  • Many (perhaps most?) mid to late 20th century
    philosophers who abandoned strict logical
    positivism (including Russell and Wittgenstein)
    still found Ayers response to this issue quite
    credible.
  • On the other hand, maybe the question is too
    obvious and important to give up on, so lets
    stumble on .
