Announcements
  • For Thursdays class review McTaggart, The
    Unreality of Time and read Russell The Problems
    of Philosophy, chapters I and II.
  • Essays are due next Tuesday July 5.
  • Tutorial exercises will be posted by tomorrow
    night please print them and bring them to
    class. We are going to focus on this tutorial
    Humes view of causality and freedom, Humes
    skepticism.

Section 9 Of the Reason of Animals
  • Not much of interest to us here
  • If animals have beliefs and reason, this could
    only be determined analogically
  • What does Hume determine
  • Animals learn but they do not reason
  • Animals learn
  • ..It seems evident, that animals, as well as men
    learn many things from experience, and infer,
    that the same events will always follow from the
    .

3
Fido learns
  • same causes. (70)
  • In all these cases, we may observe, that the
    animal infers some fact beyond what immediately
    strikes his senses and that this inference is
    altogether founded on past experience (70)
  • But Fido doesnt reason
  • It is impossible, that this inference of the
    animal can be founded on any process of argument
    or reasoning, by which he concludes, that like
    events must follow like objects and the course.

4
Fido doesnt reason
  • of nature will always be regular in its
    operations (70)
  • They seem to have beliefs
  • It is custom alone, which engages animals, from
    every object, that strikes their senses, to infer
    its usual attendant, and carries their
    imagination, from the appearance of the one, to
    conceive the other , in that particular manner,
    which we denominate belief.(71)

5
Does Fido have beliefs?
  • The behavioural evidence often seems to suggest
    that they do. However, philosophers have cast
    doubt on such evidence.
  • If an animal is said to have beliefs, if we
    attribute such beliefs to them, then we should
    understand the nature of belief. We should know
    what it is that we are attributing to them.
  • And in considering the nature of belief two
    considerations cast doubt , considerable doubt,
    on the strength of the behavioural evidence (1)
    holism (2) semantic opacity.

Section 10 Of Miracles
  • Sections 10 and 11 contains Humes attack on
    religion.
  • Or is it an attack? That is something we will
    have to debate.
  • The Target Christianity
  • However, though this is the specific target, what
    Hume argues applies to any faith that has a
    belief in sacred texts predicated upon divine
    revelation and/or contains stories of miracles.

7
Of Miracles
  • Many Christians in Humes day considered miracles
    to be a proof for their religion. God is a
    supermagician, forced to stage public appearances
    with a spectacular show of miracles in order to
    gain self-confidence and recognition.
  • Definition of a miracle
  • A miracle may be accurately defined, a
    transgression of a law of nature by a particular
    volition of the Deity, or by the interposition of
    some invisible agent. (77)

8
Of Miracles
  • Of course, for the religious the laws of nature
    are themselves a miracle (sign) that arouses
    humanitys wonder of the divine. However,
    putting that to the side.
  • A maxim of rationality
  • A wise man, therefore, proportions his belief to
    the evidence. In such conclusions as are founded
    on an infallible experience, he expects the event
    with the last degree of assurance, and regards
    his past experience as a full proof of the future
    existence of the event. (73)

9
Of Miracles
  • The reason why the laws of nature carries so much
    weight is that they are predicated upon the
    uniformity of experience.
  • Now Hume needs to do a little more work here in
    distinguishing what is a miracle from
    inexplicable freaks of nature and other such
    irregular experiences. He needs to do a little
    more work in what exactly violates a law of
    nature and what are just irregular experiences.
    For he states

10
Of Miracles
  • One, who in our climate, should expect better
    weather in any week of June than in one of
    December, would reason justly, and conformable to
    experience.All effects follow not with like
    certainty from their supposed causes. Some
    events are found to have been more variable, and
    sometimes to disappoint our expectations so
    that, in our reasonings concerning matter of
    fact, there are all imaginable degrees of
    assurance, from the highest certainty to the
    lowest species of moral evidence. (73)

11
Of Miracles
  • From this quote there are invariable experiences
    codified in laws and are considered certainties.
  • Others are irregular with ALL imaginable degrees
    of assurance, where their probability are lower.
  • So when is something a suspension of the laws of
    nature due to the intervention of the divine and
    when is it just an irregularity?
  • How low does probability have to go to be
    considered a miracle? Remember the miracle
    we did on the board last week.

12
Of Miracles
  • Must a miracle happen only once? If miracles
    do happen somewhat frequently according to
    various religious traditions, would they have a
    regularity and uniformity to them so that all
    Hume is ultimately arguing is that he just
    doesnt believe them? This is not Humes claim.
  • Since, as Hume maintains, there is no necessity
    in the outer world, so much so that there is no
    contradiction involved in existential statements,
    can he make sense of the idea of a physically.

13
Of Miracles
  • .impossible event? What could such
    impossibility consist in since it couldnt be a
    contradiction?
  • All of these questions are interesting of a
    theoretical level but perhaps we can put them
    aside as not touching Humes main argument (?).
  • It is commonly believed though not universally
    especially in Humes day that if a miracle had
    a rational explanation it wouldnt be a miracle

14
Of Miracles
  • Therefore, we can accept by definition that a
    miracle is a violation of the laws of nature
    putting aside the interesting question of
    precisely when is anything a violation of a law
    of nature when there are no natural causes?
    How is this determined? All irregular events
    appear so.
  • The maxim of rationality forms the fundamental
    basis for why we believe in historical reports
  • The reason, why we place any credit in
    witnesses, and historians, is not derived from a
    connexion, which we perceive a priori, between
    testimony and reality, but because we are
    accustomed to find

15
Of Miracles
  • .a conformity between them. (75)
  • Something must agree with our experience if we
    are to believe it.
  • And now we have the key ingredients of Humes
    argument against miracles.
  • 1.Weaker evidence can never undermine stronger
    evidence.
  • 2. We proportion our beliefs according to the
    stronger evidence, that which is more probable.

16
The argument
  • 3. A natural explanation of an event and the
    testimonies given of that event even if
    improbable and seemingly unlikely is ALWAYS more
    probable than the miraculous.
  • Therefore,
  • 4. Testimonies given of a miracle such as
    found in the Torah, Bible or Koran can never
    repeal this requirement of rationality.
  • Therefore,
  • 5. Miracles are not to be believed in.

17
The Argument
  • There must, therefore, be a uniform experience
    against every miraculous event, otherwise the
    event would not merit that appellation. And as
    an uniform experience amounts to a proof, there
    is here a direct and full proof, from the nature
    of the fact, against the existence of any
    miracle nor can such a proof be destroyed, or
    the miracle rendered credible, but by an opposite
    proof, which is superiorThat no testimony is
    sufficient to establish a miracle, unless the
    testimony be of.

18
The argument
  • .such a kind, that its falsehood would be more
    miraculous, than the fact, which it endeavours to
    establish (77) This will never happen
  • Applied to Christianity
  • It can be, and is often, argued that the
    disciples/apostles were men of integrity, died
    for their faith, were cowards at first then
    struck with bravery, had nothing to gain
    especially since most lived in poverty and were
    persecuted, had .

19
Applied to Christianity
  • .nothing to gain in that Jesus could still have
    been revered as a great rabbi (teacher) and the
    resurrection went counter to their Jewish
    expectations, were quite rational in that the
    Bible contains sophisticated reasonings as well
    as numerous admirable moral precepts about loving
    thy neighbour and not judging others. Therefore,
    why would they lie, die for a lie, and become
    hypocrites to their own moral teachings?

20
Applied to Christianity
  • On a Humean account, all of this could be granted
    though as we shall see in Part Two Hume is not so
    generous to those testifying of miracles.
  • However, though the probability of some kind of
    conspiracy account or theory here be low, maybe
    even extremely low, it is still higher than any
    supernatural or miraculous event. Thus, we cannot
    rationally believe the account.
  • Question Is this nothing more than a prejudice
    against the supernatural?

21
A Prejudice
  • For, if a miracle happened to you, you wouldnt
    be able to tell anyone about it since all of us
    are rationally required not to believe you no
    matter how honest or critically aware you are.
    Are we pre-judging, saying in effect that since
    miracles dont happen, we will not believe in
    them?
  • Note the scope of Humes argument
  • He is not proving that miracles are impossible
    how could an empiricist prove that, especially
    given the inability to state a physical
    impossibility.

22
Scope
  • And given our apparent openness to experience.
  • But rather,
  • It is never rational to believe in the report of
    a miracle. All other alternative explanations
    will be more probable.
  • Though this is the strict scope of his argument
    it should be noted that a committed Humean and
    /or naturalist would be strongly inclined to seek
    any alternative were a miracle to happen to
    them which is not hard to do since, as mentioned.

23
Scope
  • previously, apparently inexplicable freaks of
    nature do happen.

24
Section Ten Part Two
  • Adds nothing much to Humes central argument. I
    have already presented Humes argument that even
    if miracle reports are treated in their best
    possible light, they are still without rational
    foundation.
  • This section is mostly a mixture of some useful
    advice to keep our critical antennae up high in
    hearing such stories and some not so useful
    elitist ad hominem

25
The validity of eye-witness accounts
  • Four Arguments against
  • (1) For first, there is not to be found, in all
    history, any miracle attested by a sufficient
    number of men, of such unquestioned good-sense,
    education and learning, as to secure us against
    all delusion in themselves of such undoubted
    integrity, as to place them beyond all suspicion
    of any design to deceive others of such credit
    and reputation in the eyes of mankindyou get
    the point

26
Four Arguments
  • Apologists for every religious tradition would
    disagree. Smacks too much of ad hominem here.
  • (2) Peoples passions for juicy stories and
    neediness can make them gullible.
  • The passion of surprise and wonder, arising from
    miracles, being an agreeable emotion, gives a
    sensible tendency towards the belief of the
    events from which it is derived (78)
  • Useful advice here. Be careful. Especially when
    the collection plate is being past around.

27
Four Arguments
  • (3) Such stories abound in the ignorant masses
  • It forms a strong presumption against all
    supernatural and miraculous relations, that they
    are observed chiefly to abound among ignorant and
    barbarous nations or if a civilized people has
    ever given admission to any of them, that people
    will be found to have received them from ignorant
    and barbarous ancestors(79-80)
  • Civilized people such as the ones in Humes day
    who were practicing slavery, could only believe

28
Four Arguments
  • in miracles as an inheritance from barbarous
    ancestors.
  • Smacks too much of elitism the masses are asses
    and we the educated are so much better.
  • (4) Every rival system has their miracle
    stories so who is to be believed and dont they
    all cancel each other out?
  • What does this do to religion, here Christianity

29
The Effect
  • Our most holy religion is founded on Faith, not
    on reason(89)
  • So that, upon the whole, we may conclude, that
    the Christian Religion not only was at first
    attended with miracles, but even this day cannot
    be believed by any reasonable person without one.
    Mere reason is insufficient to convince us of
    its veracity (90)
  • But how to interpret these statements?

30
The Effect
  • Some Scholars Hume wrote such statements as
    these to protect himself from the wrath of the
    authorities. And when you read them, especially
    the last one, they are not at all complementary
    of religion.
  • Others we cant read into the text such
    motivations but must accept them at face value.
    Besides, what Hume says in his first argument
    which would apply to the Biblical writers shows
    that he doesnt really care about being in such.

31
The Effect
  • trouble. Religion is without rational
    foundation. But so is (a) belief in an external
    world (b) induction that the future will
    conform to the past (c) the continued existence
    of objects. Religious beliefs are justified
    solely by faith.
  • Ill leave it for you to decide what you take
    these statements to imply
  • Hume himself? Definitely too much of a skeptic
    to advocate atheism. But beyond that it is the
    subject of debate which I not being a Hume

32
The Effect
  • ..scholar will not comment on. Some argue
    agnosticism, others attenuated deism, fideism,
    - on such a murky subject unless I am confidently
    in the know, I will keep quiet. Read The
    Dialogues Concerning Natural Religion and come
    to your own conclusion.

Section 12 Of Academical or Sceptical Philosophy
  • Part One
  • Central Thesis Reason does not possess the
    resources to act as a foundation or justification
    of any kind, for our beliefs. Beliefs that we
    hold to be self-evidently true cannot be
    substantiated through any rational argument. In
    fact, rational arguments actually disqualifies
    such beliefs. Ultimately, what acts as the
    foundations for beliefs are natural instincts.

35
The Varieties of Skepticism
  • (1) Cartesian Skepticism the thesis of
    universal doubt.
  • (2) A moderate version that is actually
    beneficial for us
  • (3) Consequent to science and enquiry
  • (a) With respect to the senses
  • (b) With respect to the distinction between
    primary and secondary qualities.

36
Cartesian Skepticism
  • Recall from Descartes the procedure of
    methodological doubt.
  • What would happen if we were to adopt this form
    of doubt? That is, if we could?
  • There would be no escape.
  • But neither is there any such original
    principle, which has a prerogative above others,
    that are self-evident and convincing Or if
    there were, could we advance a step beyond it,
    but by the use of those very faculties, of which
    we are supposed

37
Cartesian Skepticism
  • .to be already diffident. The CARTESIAN doubt,
    therefore, were it ever possible to be attained
    by any human creature (as it plainly is not)
    would be entirely incurable and no reasoning
    could ever bring us to a state of assurance and
    conviction upon any subject. (103)
  • Even if we could obtain an original principle
    we could not advance a step beyond it.
  • Have we seen this in Descartes?

38
Cartesian Skepticism
  • The Cartesian Circle?
  • (2) A moderate version of skepticism
  • A careful method freed from prejudices and rash
    judgments. Impartial, restricted to that which
    is within the scope of reason to pronounce
    judgments upon but not allowing itself to extend
    further than this.
  • To begin with clear and self-evident principles,
    to advance by timorous and sure steps, to review
    frequently our conclusions, and examine ..

39
Moderate Skepticism
  • .accurately all their consequences though by
    these means we shall make both a slow and a short
    progress in our systems are the only methods, by
    which we can ever hope to reach truth, and
    attain a proper stability and certainty in our
    determinations. (103)
  • Ultimately, it is this form of skepticism that
    Hume is going to advocate.
  • (3) Consequent to Science and Enquiry

40
Consequent to Science and Enquiry
  • (a) with respect to the senses
  • What beliefs doe we naturally hold to be
    self-evidently true?
  • (1) What we are directly aware of in sense
    perceptions are the objects of such perceptions.
    I am seeing this table here and now.
  • (2) The external world. The objects of our
    beliefs are the familiar objects just as we
    perceive them to be in the external world. Such
    objects are the source of our sense perceptions.

41
Beliefs we hold true
  • (3) Of such objects our presence bestows not
    being on it Our absence does not annihilate it.
    It perserves its existence uniform and entire,
    independent of the situation of intelligent
    beings, who perceive or contemplate it. (104)
    What we have here is actually two distinct though
    related beliefs (a) the continuous existence of
    objects they remain in existence even when we
    are no longer perceiving them (b) our familiar
    problem of induction the future will conform to
    the past.

42
Their rational support?
  • Of (1) reason shows us to be false. What we
    are directly aware of, what we have contact with,
    are our perceptions ideas, representations,
    sense-datum, perceptions in Hume from which we
    need to infer a source an inference that is not
    possible for us to rationally make.
  • Of (2) and (3), they are without rational
    foundation. We cannot demonstrate them to be
    true or false.
  • In many respects such a conclusion for (2) and
    3(a) follows from (1).

43
Of (1) what does reason show us?
  • The table, which we see seems to diminish, as we
    remove farther from it But the real table,
    which exists independent of us, suffers no
    alteration It was therefore, nothing but its
    image, which was present to the mind. These are
    the obvious dictates of reason and no man, who
    reflects, ever doubted, that the existences,
    which we consider, when we say, this house and
    that tree, are nothing but perceptions in the
    mind, and fleeing copies or representations of
    other existences, which remain uniform and
    independent. (104-5)

44
Of (1)?
  • Note Keep this argument in mind. We are going
    to see one very similar if not identical to
    it when we come to Bertrand Russell. There I
    will present a critique.
  • We have varying different perceptions of the
    table i.e., it can appear in a different shape,
    smaller and different colour depending upon my
    position of perception while we believe the
    table itself to remain the same. What this is
    suppose to convince us of is that what we are in
    contact

45
Of (1) ?
  • with are our perceptions themselves.
  • Having establish this, (2) can be placed in
    skeptical doubt.
  • By what argument can it be proved, that the
    perceptions of the mind must be caused by
    external objects, entirely different from them,
    though resembling them (if that be possible) and
    could not arise either from the energy of the
    mind itself, or from the suggestion of some
    invisible and unknown spirit(105)

46
Of (2)?
  • We have our familiar correspondence or vantage
    point problem. Recall how do we demonstrate
    that our perceptions (ideas, sense-datum)
    corresponds to the way objects are if all that we
    possess are our perceptions? From what vantage
    point do we verify the correspondence?
  • From experience? What is the problem with this
    suggestion?
  • And Hume Agrees.

47
Of (2)?
  • But here experience is, and must be entirely
    silent. The mind has never any thing present to
    it but the perceptions, and cannot possibly reach
    any experience of their connexion with objects.
    (105)
  • From what vantage point? We are stuck on one
    side of the claimed relation between thoughts and
    objects and therefore cannot validate both sides
    of the relata. We cannot demonstrate what the
    source on the other side of the relation is.
    Therefore, according to reason, the external
    world is lost.

48
Appeal to God?
  • No. Two reasons given.
  • (1) A perfect God would create our sense
    experiences to be perfect because it is not
    possible that he can ever deceive (105).
    However, we are not infallible.
  • (2) If we can doubt the external world, we have
    removed the basis from which we can prove the
    existence of God.
  • Two Questions
  • (1) How does Descartes respond to (1) ?

49
Two Questions
  • (2) Why does Hume hold (2)? Think of his
    critique of the ontological argument.
  • Once we grant the argument concerning how what we
    are fundamentally in contact with are our
    perceptions can you see how 3 (a) escapes
    rational justification and proof?
  • And 3 (b) is just our familiar problem of
    induction.
  • Therefore, what is the foundation for all such
    beliefs? An instinct of nature. Thats it.

50
(b) Primary and Secondary Qualities
  • Recall from Descartes. What is the distinction?
  • Basic thesis Primary qualities are just as much
    in the mind as secondary qualities. Therefore,
    if secondary qualities are not really real or
    objective then neither are primary qualities.
  • Supporting argument
  • Do we ever detect, and even stronger, can we ever
    effect, a separation of primary and secondary
    qualities? Hume couldve said here from what
    impression do we have such a separation

51
Supporting Argument
  • What is extension without a shape, a colour, a
    hardness etc.
  • An extension, that is neither tangible nor
    visible, cannot possibly be conceived And a
    tangible or visible extension, which is neither
    hard nor soft, black nor white, is equally beyond
    the reach of human conception. (106)
  • The argument Berkeleys against such general
    or abstract ideas.

52
Supporting Argument
  • But if we can effect no such distinction between
    primary and secondary and thereby consider them
    both to be in the mind
  • Bereave matter of all its intelligible
    qualities, both primary and secondary, you in a
    manner annihilate it, and leave only a certain
    unknown, inexplicable something, as the cause of
    our perceptions a notion so imperfect, that no
    sceptic will think it worth while to contend
    against it. (107)

53
Section 12 Part Two
  • Reason itself, instead of being clear and
    distinct presents us with its own paradoxes
  • Hume mentions the infinite divisibility of matter
    as an example. Finite matter yet infinitely
    divisible. Every division yields some
    matter/quantity, so how could it be infinitely
    divisible?
  • There are others (i.e., Russells paradox)
  • Note in part one Hume casts skeptical doubt
    concerning matters of fact and existence. Here

54
Part Two
  • he wishes to show that mathematics is not immune
    to such doubts either. This corresponds nicely
    to his division of reason at the beginning of
    section four between relations of ideas and
    matters of fact. The upshot all of reason is
    vulnerable to skeptical attack and weakening.
    Reason has a limited domain.
  • Note the difference with Descartes. With
    Descartes, we can fully trust our clear and
    distinct ideas.

55
The power of Skepticism
  • So what should our reaction be to such a power of
    skepticism? Do we face utter paralysis? A
    Hamlet state where we are unable to act since
    reason cannot be our guide?
  • No to the latter two questions. Nature saves the
    day Nature is always too strong for principle
    (100).
  • The excessive skeptic Pyrrhonian will
    ultimately destroy herself.

56
Excessive Skepticism
  • On the contrary, he must acknowledge, if he will
    acknowledge any thing, that all human life must
    perish, were his principles universally and
    steadily to prevail. All discourse, all action
    would immediately cease and men remain in a
    total lethargy, till the necessities of nature,
    unsatisfied, put an end to their miserable
    existence. (110)
  • Interesting the life guided purely by reason.
  • However, nature will intrude and set the matter
    straight.

57
Excessive Skepticism
  • the first and most trivial event in life will
    put to flight all his doubts and scruples, and
    leave him the same, in every point of action and
    speculation, with the philosophers of every other
    sect, or with those who never concerned
    themselves in any philosophical researches
    (110-11)
  • So much so that the excessive skeptic will be
    forced to laugh at herself and the whimsical
    condition of mankind, who must act and reason and
    believe. (111)

58
Excessive Skepticism
  • Does this satisfy us? Will it encourage its own
    form of dogmatism? Laziness? Shouldnt we keep
    working on the hard problems of reason? Would
    such an attitude discourage this?
  • Summary. The arguments against excessive
    skepticism
  • (1) Produces no good or useful outcomes. Nothing
    good arises from it.
  • (2) Paralyzes action leading to a miserable
    life.
  • (3) Ultimately produces no conviction nature
    is too strong.

59
Excessive Skepticism
  • (4) Unanswerable leaving us nowhere to
    concentrate our research efforts.
  • However, in this section, the skeptic who keeps
    with his proper sphere, and display those
    philosophical objections (110) will have ample
    matter of triumph (110)
  • As in the previous section Hume speaks favourably
    of a moderate skepticism that appreciates and
    doesnt attempt to transgress its limits. Read
    the summary on page 110. Who does it remind you
    of?

60
Part Three Humes Conclusions
  • The moderate brand of skepticism Hume favours is
    here called mitigated or academical
    skepticism.
  • Its benefits (a) Cautious study.
  • (b) Modesty, humility
  • (c) Contrary to dogmatism
  • (d) Knows and accepts its limitations and scope.

61
Limitations
  • A correct Judgment observes a contrary method,
    and avoiding all distant and high enquiries,
    confines itself to common life, and to such
    subjects as fall under daily practice and
    experience leaving the more sublime topics to
    the embellishment of poets and orators, or to the
    arts of priests and politicians.But they will
    never be tempted to go beyond common life, so
    long as they consider the imperfection of those
    faculties which they employ (112)

62
Limitations
  • Question such sublime topics left to the
    poets, priests and politicians are some of the
    most important issues facing the human being. No
    one has gone to war over a scientific theory or
    mathematical formula however, unfortunately, we
    have over such topics. Such topics of life and
    death, war and peace, of art and religion
    inspire the human being enabling her to reach the
    greatest heights of imagination, wonder and
    compassion. And also the greatest lows of the
    human being.

63
Question
  • Shouldnt we expect, shouldnt we demand, that a
    correct judgment have something to say here?
    Or so we say that if it cannot be studied
    mathematically or scientifically, it just doesnt
    exist? Is nothing to say actually the best
    response? Does Hume ultimately lead to a social
    conservatism?
  • Question considering Humes division in section
    one between the easy and obvious philosophy where
    a philosopher who purposes only to represent the
    common sense of mankind in.

64
Question
  • ..more beautiful and more engaging colours, if
    by accident he falls into error, goes no farther
    but renewing his appeal to common sense, and the
    natural sentiments of the mind, returns into the
    right path, and secures himself from any
    dangerous illusions (2), and abtruse thought
    which is dangerous. With Humes emphasis on the
    common life and nature in the above quotes, is
    he ultimately supporting and vindicating the
    easy and obvious philosophy?

65
The proper objects of Study
  • What should we be investigating? What should we
    be spending our intellectual labour and effort
    on?
  • Relations of Ideas demonstrative (mathematics)
  • Matters of Fact the sciences
  • And thats it. They are the only sources of
    knowledge.

66
Humes Criteria
  • Sometimes referred to as Humes Fork
  • When we run over libraries, persuaded of these
    principles, what havoc must we make? If we take
    in our hand any volume of divinity or school
    metaphysics, for instance let us ask, Does it
    contain any abstract reasoning concerning
    quantity or number? No. Does it contain any
    experimental reasoning concerning matter of fact
    and existence? No. Commit it then to the
    flames For it can contain nothing but sophistry
    and illusion.

67
Humes Criteria
  • A philosopher has presented us with a criteria.
    We know what to do. It is?

68
Humes Criteria
  • So lets ask it of Humes book.
  • Does it contain any abstract reasoning concerning
    quantity or number? No. It is not a work of
    mathematics.
  • Does it contain any experimental reasoning
    concerning matter of fact and existence? No. It
    is not a work of scientific investigation and
    experiment.
  • So what are we suppose to do with the Enquiry?
  • Commit it to the flames For it can contain..

69
Humes Criteria
  • .nothing but sophistry and illusion.
  • How odd?
  • Has Hume opened the door to a proper field of
    study and knowledge only to attempt to close it?
    Adopting a vantage point, a meta-level, that
    attempts to absolutize itself by disqualifying
    its own possibility?

McTaggart, The Unreality of Time
71
Skeletal Outline of McTaggarts The Unreality of
Time
  • Five Basic Movements
  • (1) Our understanding of temporality divides
    into two kinds the A series and the B
    series
  • (2) Despite initial appearances, it is the A
    series that is essential for time the B
    series is derived from, predicated upon, the A
    series for its legitimacy

72
McTaggart Outline Continued
  • (3) Therefore, time can only be real as the A
    series
  • (4) The A series is incoherent and
    self-contradictory
  • (5) Therefore, time cannot be real.

73
What to watch for
  • Therefore, in your reading follow carefully steps
    (1) (5)
  • i.e., clearly identify what the A series is and
    how it differs from the B series
  • i.e., why is the B series parasitic upon the A
    series? What are the arguments? How does
    considerations surrounding change play a role?
  • i.e., how does the argument designed to show that
    the A series is self-contradictory work?

74
McTaggarts The Unreality of Time
  • The A series past/present/future
  • Includes the far past, near past, present, near
    future etc.
  • The B series the earlier than/ later than
    relation
  • Following Mellor we can define this series as the
    series of dates 2001, 2002, 2003, 2004, 2005,
    2006 etc.

75
McTaggarts The Unreality of Time
  • The B series relations are transitive and
    asymmetrical
  • transitive if A is earlier than B and B is
    earlier than C then A is earlier than C
  • asymmetrical it is not the case that if A is
    earlier than B then B is earlier than A that
    would be a symmetrical relation

76
McTaggarts The Unreality of Time
  • Since the A series involves tenses past tense,
    present tense, future tense we can call this
    the tensed view of time
  • Since the B series doesnt involve such tenses
    only the earlier than/ later than relation
    and/or dates - we can refer to this as the
    tenseless view of time

77
McTaggarts The Unreality of Time
  • The tenseless view of time appears more
    fundamental and objective
  • Why? Because the tensed view of time seems to
    require a subject and therefore appears to be
    merely subjective past to whom?
    Past/present/future appears relative to us
    whereas dates are permanent and thereby appears
    more objective and real

78
McTaggarts The Unreality of Time
  • Characteristic of the B series tenseless view
    of time its relations are permanent
  • If A is earlier than B then this is forever so
  • May 9, 2005 was earlier than June 9, 2005 period
  • By contrast the A series is not characterized
    by its permanency an event occurring now will
    become past, near past, far past. A future event
    will become closer and closer

79
The Fundamental Series
  • So is the B series more fundamental and real?
  • No - it is actually the A series that is
    fundamental for time
  • The argument
  • Change is essential for time
  • i.e., if nothing ever changes, if nothing ever
    became different, then we would not be able to
    state or understand A became B before C became
    D and after E became F

80
The Fundamental Series
  • Without such changes there would be no situations
    in which before and after could be used or
    even understood
  • Since change is essential for time our question
    then becomes Is there change in the B series?
  • No. This relates to the permanency
    characteristic we mentioned above
  • M is earlier than N which is earlier than O MltNltO

81
The Fundamental Series
  • Such relations are permanent M,N,O are points
    in time in the B series and such relations are
    static and permanent
  • But M changed into N at a certain moment
  • Yes, but introducing at a certain moment is
    introducing a now, a present in other words,
    introducing a tense
  • Such tenses are not part of the tenseless view of
    time

82
An analogy
  • How should we think of this argument?
  • Think of the B series as a map without a you are
    here symbol
  • (1) without the symbol is the map useful to us?
    No. But that may be just subjective. It is
    after all an objective and complete
    representation of spatial relations

83
An analogy
  • BUT when we move from Mississauga Road to Bay
    Street (maybe that is a trip some of you are
    planning to make) is there any travel in the
    map qua map? No, the map is as it is. WE are
    moving our finger along the map and that is the
    travel that is being done but there is no such
    travel in the map itself as an accurate
    representation of spatial relations

84
An analogy
  • Map B series
  • Travel change
  • In keeping with our analogy, in the second part
    of McTaggarts article where he argues that time
    is unreal, one of the basic points of his
    argument or so I shall argue - will be that
    whereas in a map you can give a complete and
    accurate representation of spatial relations
    hence, real and objective there is no such map
    of time

85
An analogy
  • Time, in contrast to spatial relations, will
    require a you are here symbol in order to be
    made sense of
  • All to come
  • Therefore, change requires the A series
  • How to think of change with respect to time and
    the A series?
  • Event you writing the test on June 9 (McT.s
    example the death of Queen Anne)

86
Time and Change
  • Event you writing the test on June 9
  • All the characteristics of this test writing are
    stamped in time felt confident/needed more
    time/studied too much/little.
  • Event now and forever was on June 9
  • Let x represent the test being written

87
Time and Change
88
Time and Change
  • Where do we see the change in this table?
  • In column B the B series - there is no change
    May 20 is ALWAYS later than May 9 and earlier
    than June 9 by the same constant unchanging
    intervals these dates as points on a line do not
    alter
  • In the A column the A series we note change
    in the changing tenses was distant future, near
    future, present, past, etc. -quote from p.13

89
Time and Change
  • Or to continue with our map analogy you are the
    you are here symbol, the temporal frame of
    reference, in the test being written while the
    dates remain fixed and unchanged
  • As you travel, come closer to the event change
    occurs
  • However, the key point is that it is only in the
    A series with such a reference point whereby
    past/present/future can be articulated, within
    the river of time itself can change occur

90
Time and Change
  • Change is the changing tense of things and events
    moving from the past to the present to the future
  • Points on a line as we find in the B series do
    not change such points are just located at
    different parts of the B series i.e., a poker
    analogy
  • Such ever changing tenses define the earlier
    than/later than relation itself
  • Therefore, the B series is derived from the A
    series

91
Some Conclusions
  • Therefore, no A series --- no change
  • Therefore, B series is not sufficient to
    constitute time given that change is essential to
    time
  • Therefore, B series as a temporal series is
    dependent upon the A series
  • Therefore, if the A series is incoherent then
    time is incoherent and unreal

92
Three Objections
  • (1) Russell
  • Past/present/future belongs only to the subject
  • Makes sense in the analogy above I have stated
    that you are the you are here symbol
  • Past/present/ future are token reflexive
  • Defn terms such as I, here, now whose
    essential occurrence in a sentence renders that
    sentence capable of bearing different truth
    values according to the circumstances of utterance

93
Three Objections continued
  • Examples Today is sunny, I am at UTM, I am
    at UTS etc.
  • Russell such token reflexives does not belong
    to time
  • No subjects/ human beings events could still be
    earlier than/ later than each other
  • Implicit also if we wish to give an objective
    complete description of reality we cannot
    tolerate constant fluctuating truth values
    i.e., the map

94
Three Objections continued
  • Russells idea to think of change as difference
    in truth values
  • The test is being written as asserted on May 9
    False
  • The test is being written as asserted on June 9
    True
  • Note change in truth values therefore, change
  • A relation between a proposition, date (B series)
    and truth value

95
Three Objections Continued
  • Note in such a relation no seeming mention of
    the A series, tenses just the proposition, date
    (B series) and truth value
  • McTaggarts response his poker example or in
    our example such truth values whether T or
    F are eternally true or false they are thus
    fixed and unchanging
  • The test is being written as asserted on May 9
    False and always, eternally false

96
Three Objections Continued
  • The test is being written as asserted on June 9
    True and always, eternally, true
  • Therefore, whence the change? These facts in (1)
    and (2) never, and will never, change
  • But the change is in the in-between (1) and (2)
    when I assert it on May 9 as opposed to when I
    assert it on June 9
  • Quite right but now notice the return of the
    subject, the I, the you are here point!

97
Three Objections Continued
  • The change is captured in the as asserted and
    now we are back in the A series
  • The as asserted the proposition as sometimes
    T sometimes F is where change happens
  • Yet in such a listing of dates with these fixed
    truth values we are not going to get a sometimes
    T, sometimes F phenomena
  • Russell doesnt want any such ambiguity always
    true/ always false therefore, as always no
    change

98
Three Objections Continued
  • Second Objection Non-existent time series the
    adventures of Don Quixote
  • Don Quixote as fictional cannot be said by us
    to be past/present/future
  • But as we read the book we grasp without this the
    earlier than/later than relation as temporal
  • Therefore, B-series is all we need

99
Three Objections Continued
  • McTaggarts Response (1) why are we talking
    about anon-existent time series to prove the
    existence of time? No sense
  • weak hypothetical thought experiments
    including fiction elicits truth? It is precisely
    the role of the imaginary to bring real things
    to light. If in our reading of fiction we can
    grasp temporal relations without the A series,
    then the A series is not fundamental, essential
    or necessary for time regardless of the fact that
    it is fiction.

100
Three Objections Continued
  • Second Response better our grasp of these
    adventures can only be in the A-series as if
    they really happened (15) here I may be
    strengthening McTaggart a little beyond what he
    literally says but only a little
  • All that is real i.e., Cervantes mind when he
    invented the story is in the A - series

101
Three Objections Continued
  • Several Real and independent time series
  • The argument p.15
  • Present is a marker only on each line, within
    each line
  • Yet our ability to distinguish such presents is
    not as successive yet, we can still distinguish
    them
  • But the present can only be real if it is
    successive

102
Three Objections Continued
  • The different time series are real
  • Therefore, these different time series must exist
    independently of past/present/future
  • McTaggarts response in our overview of such
    time lines, there is no present since the present
    can only be successive
  • But what is time without the present therefore,
    there is no time from such an overview

103
Three Objections Continued
  • Our mistake was to derive certain characteristics
    of the overview itself and impute them on each of
    the members - which is the real time series
  • The way McTaggart responds does strike one as
    simply begging the question what is being
    challenged is precisely whether we can grasp the
    present non-successively as this objection
    states
  • However, one fruitful manner of understanding
    this response maybe strengthening it.

104
Three Objections Continued
  • In some informal logic textbooks there is a
    fallacy called division where one aspect of
    this fallacy is to argue fallaciously from the
    attributes of a collection of elements to the
    attributes of the elements themselves

105
Three Objections Continued
  • For example, university students collectively
    study medicine, law, engineering, philosophy,
    dentistry etc. therefore, each student
    individually studies medicine, law, engineering,
    philosophy etc.
  • It doesnt follow.
  • With this objection we see a similar structure
    (albeit not quite identical) collectively the
    present of these time series which we
    understand and are real can be understood
    non-successively and yet the present can only be
    the present successively

106
Three Objections Continued
  • Therefore, we can understand individually each of
    these time series without the distinction between
    past, present, and future
  • Here we see double division (I) the alleged
    incompatibility between the collective present
    non-successive- and the individual present
    successive an incompatibility only b/c we have
    fallaciously juxtaposed the characteristics of
    the collection and the individual elements

107
Three Objections Continued
  • And (II) the inference that since collectively we
    can understand the present as not the present we
    can understand individually each time series
    without the present
  • Is it any surprise that McTaggart returns the
    discussion to what must be true of the individual
    case

108
Concluding Remarks of First Part
  • After answering such objections
  • We conclude, then, that the distinctions of the
    past, present, and future are essential to time,
    and that, if the distinctions are never true of
    reality, then no reality is in time (16)
  • Now McTaggart has to show that the A series
    involves a contradiction and therefore, time is
    unreal
  • Stay Tuned - Cheers
