aversion to lying
3Liars paradox Syntax language
- The classic statement
- This sentence is false
- If this sentence is false is true then the
sentence is false. - But if this sentence is false is false, then
the sentence is true.
4De Chardins Noosphere
- Focus on the sphere of mind according to Huxley
- A conscious awareness of lying through the
interaction of the human mind with other minds - Sensation and perception ..the extended mind
- Kant these aspects of the mind turn
things-in-themselves into the world of
experience. - McGilchrist Left prefrontal cortex and wrong to
believe that telling a lie can make us unhappy. - Lying awareness and experience within a lying
life cycle
5Liars paradox Meaning awareness
- Masha Isnt there some meaning?
- Toozenbach Meaning? Look out there, its
snowing. Whats the meaning of that? - Mary Lincoln Does this dress make my backside
look big? - Abe Lincoln Perhaps a bit.
6Meaning awareness
- We cannot judge the truth. We can only interpret
the sense data through the intellect and grasp
the truthDemocritus 460-370BC - At a moment in time we recognize well signed
turning points in conversation and we have to
shift to a different kind of languageMary
Midgley 21st century
7Adapting de Chardins noosphere
- The duration of a lie is independent of the truth
a form of deception - Lying is at a moment in time. Descartes mediation
bring it about I you. - Observation Jean Valjean and the loaf of
bread. St Francis of Assisi and the murderer. - There is a layer of consciousness surrounded by
years of thought experience. Individuals know
that they have to shift to a different kind of
language.
8Two hypotheses
- Truthful honest individual tells a lie
- Willy Loman hypothesis an economic incentive to
lie 110 chance (tell the truth) of earning 5
commission or 5050 chance (tell a lie).. - Girards Mimetic hypothesis unconscious tendency
to adopt the aspirations of others - lying has
value because it is desired by another.
9Lying life cycle
- Lukes power and influencing belief systems
Vladimir and Estragon Waiting for Godot - Pandering Mr T in conversation with the
distraught mother of a lost child Your daughter
is in Vermont. True or False? - Example of Leo the liar L/T and a Kohlberg
question what is in it for me? - Rosenbaum There is no central supervising self
inside Mr T but a conscious awareness T/L
10Prefrontal cortex
- Prefrontal cortex regulates emotions and
behaviour studies on sleep-deprivation SD and
a link to persons emotions and behaviour. - 2014 Study Journal of Applied Psychology
Students were more inclined to lie when sleep
deprived - Dan Arielys 2008 study that showed incidence of
cheating many who cheated a little rather than
a few who cheated a lot.
11white lies evolve into lying as a norm Copes
law of lying?
- We are pluralities T evolves to T/L and L
evolves to L/T What is in it for me? My payoff? - Many T/L Few L types Dan Arielys experiment
with cheating amongst students as many students
cheating a little - Lying because everyone is lying Cascade effect
of a lying life cycle - analogous to restaurant
queues.
12Waiting for truth Lies concealed in truth
Figure 1
- Cohens Non-equivalence
- Statement L is T. Statement L is like T
- L as T creates a metaphorical risk that L is
T - Is there an equivalence?
- Yes, Figure 1 a topology
- L proper subset T ? L as T
- L is T gt L T if and only if T L
- L is T is understood to be L is like T
13Turing Experiment and Benthams Panopticon
- Turing Test if a machine convinces observers it
might be rational, then it is fair to describe
the machine as rational. - Statement 1 the respondent behind the closed
door is a liar - Statement 2 the respondent in Statement 1 is a
liar. - Statement 2 is True if and only if Statement 1 is
Not False
14Table 2 Person l Machine t/l
Mr L T/L Identity
Are you a liar? Yes No
Can I trust you? Yes No Mr L
15Liars paradox No Awareness
- Statement 3 L is a liar
- A sentence is False if its negation is True
- If Sentence 3 is not false, then it is false. It
is false. But since this is what Sentence 3 says
it is, it is true. So it both true and false. - Alternative No Liars Paradox with Awareness
- Fable of West Lake
- .
16Fable of West Lakeno Liars Paradox
- Benthams Panopticon or Hofstadter-Schellings
I-think-You-think-I-think strange loop - Statement 4 Chinese man The fish are unhappy
- Friends Reply How do you know that the fish
are unhappy? - Chinese man But you are not me. How do you know
that I know
17Lying in a moment in time v mixed speech St
Jerome Psalms 11611
- Manfreds statement S Everyman is a liar.
- Is Manfred telling the truth or is he lying?
- If it is true that every man is a liar, and
Manfreds statement S is true, then Manfred also
is lying he is a man. But if he is lying his
statement S is not true - Since Manfred himself is a man, it follows that
he also is lying but if he is lying because
every man is a liar, then his lying is of a
different sort.
18Final Causebecause
- Thinking about lying and lying are the same thing
- Lying is a final Aristotelean cause how a thing
came about ..responsible. - Lying is a final cause that for the sake if
which a thing is what it is for a cup it holds
water, for a seed it might be a plant, - For Mr T/L it is telling the truth as perceived
by others. - Aristotles Physics II.8 If, therefore, purpose
is present in art, it is present also in nature.
