Q

What is the No false lemmas definition of knowledge?
a belief or a part of reasoning which is
Does it reach the right conclusion with the Gettier case (that it doesnt count as knowledge)?
What are issues with this definition?
modifiedobjections that…, n, v

A
  • a belief or part of reasoning which is accepted true in a reasoning process
  • Yes, wouldnt count —> seems to describe knowledge well
  • ad hoc, negative, virus x
    —> made precisely to rule out the gettier cases and only tells us what shouldnt be knowledge
18
Q

What is the inafibalism definition of knowledge?
doubt
Does it reach the right conclusion with the Gettier case (that it doesnt count as knowledge)?
What are issues with this definition?
too…?

A
  • knowledge must be impossible to doubt and certain, prepositions which count as knowledge must be beyond doubt
  • yes, wouldnt count —> does describe knowledge well but rules out most things we would normally count as knowledge so actually probably doesnt describe it well
  • too narrow
19
Q

What is the reliabalism definition of knowledge?
Does it reach the right conclusion with the Gettier case (that it doesnt count as knowledge)?
What are issues with this definition?

A
  • knowledge has to be reliable, have a high % of true beliefs
  • yes, wouldnt count —> still doesnt seem to describe knowledge well
  • fake barn county, cannot describe a reliable process —> circular
20
Q

What is the virtue epistemology definition of knowledge?dispositions that…
Does it reach the right conclusion with the Gettier case (that it doesnt count as knowledge)?
What are issues with this definition?
def. of IV = ?
doesntaccount for

A
  • dispositions that aim towards the truth
  • yes, wouldnt count —> still doesnt seem to describe knowledge well
  • circular definition of intellectual virtues, doesnt seem to account for what we understand knowledge to be
21
Q

What is the tripartite definition

A
  • JTB
  • J = we are able to provide reasons for why we hold the belief that we do
  • T = corresponds w/ the world
  • B = mental state that expresses truth apt propositions that we are committed to
  • S knows that P iff
    —> P is true, S believes that P, S’ belief that P is true is justified
22
Q

What is a coherence theory of truth
-world is flat
-truth is …

A

a belief that is true if it fits with our current understanding of the world at the time
- truth is mind dependant so can change over time

23
Q

what is the correspondance theory of truth

A

a belief is true if it corresponds with reality

24
Q

why might justification not be necessary for knowledge

A
  • we dont always need to justify why we know something, we can be happy with a mere true belief
  • may also be concern about the limits of providing knowledge —> if we were continually interogated about something, we would eventually run out of reasons why we hold that belief
25
Q

why might belief not be necessary for knowledge

A

1) weak version —> it is possible to know something without believing it —> being asked a question, thinking you dont know the answer but still getting the answer correct
2) strong version —> a belief can be doubted as it is not infalliable,

26
Q

why might truth not be necessary for knowledge
2 types

A

the way we understand truth differs
- correspondance = there will always be a right/wrong answer at any moment that relates the then world
- coherence = what we currently understand to be truth may turn out to be false later

27
Q

what is epistemic luck

A

when we reach a TB via an accident

28
Q

what is the job interview example

A
  • 2 characters smith + jones
  • smith believes jones will get the job for some reason, smith also notices that jones has 10 gold coins in his pocket so —> “the person with 10 gold coins in their pocket will get the job”
  • BUT smith ends up getting the job
  • also smith finds 10 gold coins in his pocket
  • so the statement smith made was JT (by accident)
  • smiths belief = J+T so according to JTB it counts as knowledge however it is just a case of epistemic luck so shouldnt count
29
Q

what is the implication of the gettier case for JTB —> useful for 12 markers

A
  • having a JTB = sufficiant grounds for knowledge however this proves we can have JTB without having knowledge
  • therefore simply having a JTB is not sufficiant for knowldges
  • therefore JTB = false, lacking
  • therefore we need a different definition or to modify this one
30
Q

what is a lemma
- a b/p/a which is acceptrd as true ina …
- s knows thhat p

A
  • a belief, premise or assumption or any other part of reasoning which is accepted as true in a reasoning process
  • S knows that P iff
    —> P is true, S believes that P, S’ belief that P is justified, S didnt infer that P from a false lemma
31
Q

what is virus x and how does this undermine the no false lemmas definition of knowledge

A
  • despite passing the no false lemmas solution, this should not count as knowledge —> it is epistemic luck
  • smith has all the symptoms of virus x and lab results also agree with this
  • so dr jones believes that smith has virus x BUT smith actually has virus y which has all the same symptoms
  • coincidently, prior to taking the lab tests, smith also caught virus x but it was too early for this to show up in the tests
  • so dr jones has a JTB that “smith has virus x “ which includes no false lemmas
  • since there is nothing here that is false, everthing should count as knowledge
  • BUT this is just a case of epistemic luck
32
Q

infallibilism definition
hint = doubt
s knows that p iff…

A
  • impossible to doubt
  • prepositions that count as knowledge are those which are beyond doubt
  • S knows that P iff
    —> P is true, S believes that P, S’ belief thay P is true is justified and certain
33
Q

does the infallibilism definition rule out the GC
beyonddoubt
result of SE so open to

A

yes
smith had a JTB but it isnt beyond doubt —> result of sense experience so open to doubt and could be wrong

34
Q

2 issues with infallibilism

A
  • restricts severly what we can count as knowledge —> sense experience, because it is open to doubt
  • overly narrow definition, gone too far
35
Q

what is reliabilism and what are reliable and unreliable sources of info

A
  • produces a high % of true beliefs, more than false ones
    S knows that P iff P is true, S believes that P, S’ belief that P is true is produced by a reliable process
  • reliable = sense perception, information or testimony from an expert
  • unreliable = guessing, conspiricies
36
Q

How does the fake barn county undermine the relibilist definition

A
  • a man points out various objects to a child as they drive in the countryside
    —>”there is a cow/tractor/barn’’ , he has no doubt about the existence of these objects
  • he has formed this belief out of his reliable senses
  • what if he was driving through a county where all the villagers had made fake barns but the one he had pointed out was the one real barn in the whole county —> so his belief “that is a barn” is true and as a result of a reliable process but also down to luck so we do not want to count this as knowledge
  • other issues = unclear what is a reliable process and we cannot know whether process are reliable
37
Q

what is an intellectual virtue+examples
dispositions

A
  • dispositions that aim towards truth for example honesty, integrity, openness
  • S knows that P iff —> S believes that P, S’ belief that P arises from an act of intellectual or epistemic virtue
38
Q

how does Sosa define an intellectual virtue
- triple a standard

A

iff :
- it is accurate —> a true belief
- it is adroit —> result of skilfullness
- it is apt —> a true belief as a result of skilfullness
- known as triple a standard
skillfulness = not as a result of luck

39
Q

how does zagzebski define an intellectual virtue

A

iff :
- motivated by a desire to know
- it is what an intellectually virtuous person would do
- it is successful —> results in a TB

40
Q

what are the issues with VE
-doesnt account for
- reflects … rather than

A
  • reflects an ideal process for gaining knowledge rather than defining knowledge itself
  • definition doesn’t account for what we mean when we say we know something
41
Q

why does Paul ziff argue that JTB is good enough

A
  • just because we can find exceptions to JTB doesn’t make it false
  • if we are happy to accept contingent rather than real definitions of knowledge then JTB is enough
  • JTB holds in most cases except those involving epistemic luck —>exceptional and unlikely situations
  • compares JTB to ‘‘a cheetah can outrun a man’’ —> true if e.g the cheetah was weighed down but this doesn’t make the overall statement false
