Tripartite View of knowledge (Epistemology)

Question 1

Propositional knowledge

Answer 1

Knowing that (Eg. I know that elephants are heavier than mice)

Question 2

Ability knowledge

Answer 2

Knowing how ( I know how to ride a bike)

Question 3

Acquaintance knowledge

Answer 3

Knowing of (I know of Oxford University)

Question 4

Tripartite view of knowledge (JTB)

Answer 4

Propersition P is true
You believe P
Your belief in P is justified

Question 5

Problems with Tripartite view (Lucky true belief)

Answer 5

Smith and Jones want the same Job
Smith has evidence of Jones getting the job (He’s told by the president of the company)
He also sees that Jones has 10 coins in his pocket
Smith forms the belief that the man with 10 coins in his pocket gets the job
Smith ends up getting the job, and then finds out he has 10 coins in his pocket also
Therefore JTB isn’t sufficient for knowledge

Question 6

Counter to gettier case( No false lemmas)

Answer 6

1) I believe Jones has 10 coins (He sees this)
2) I believe jones will get the job(Is told this)
3) I believe the person with 10 coins will get the job
2) is a false lemma, it isn’t true as his belief is false (Jones doesn’t get the job, smith ends up getting it)

Question 7

No False lemmas (J+T+B+N)

Answer 7

Aims to strengthen JTB condition
P is true
You believe p
Your belief in P is justifed
You didn’t infer this from a false belief

Question 8

Reliabilism (RTB)

Answer 8

Replaces justified condition
P is true
You believe p
Your belief in p is produced by a reliable cognitive process (memory, perception)
Knowledge is a true belief produced by a reliable cognitive process

Question 9

Infaibillism

Answer 9

Argues that for a belief to count as knowledge, it must be justified in a way that is CERTAIN
The justification cannot be doubted
In the case of smith and jones, Infallibalism argues that smiths belief (10 coins gets job) doesn’t count as knowledge as the justification isn’t certain (He could be a brain in a vat/He mishears interviewer)
As these situations raise possibility of doubt, smiths belief doesn’t count as knowledge

Question 10

Fake barn county (counter to RTB and JTBN)

Answer 10

P1)In fake barn county, locals place up facades of barns
P2)Henry doesn’t know this as he drives through and thinks “these are barns”
P3)obviously, not knowledge as the beliefs aren’t true
P4)On one occasion he sees a real barn and thinks the same thing
P5)He’s justified through perception (Also a reliable cognitive process)
P6)it isn’t inferred through a false belief
C1)the belief is true

Shows his belief isn’t knowledge, he’s lucky. RTB would argue that Henry knows theres a barn, even though it was by luck making it false

Question 11

infallibalism is too strict

Answer 11

Infallibalism suggests that everything fails to qualify as knowledge, even basic facts as they can be doubted
I know paris is the captial of france example
-To show that infallibalism sets the bar too high, and aims to show how certainty isn’t necessary for knowledge

P1-If Infallibalism is true, I do not know that paris is the capital of france
P2- But I do know that Paris is the capital of france
C-Therefore Infallibalism is false
