how should propositional knowledge be defined ?
is knowledge the same thing as JTB?
Assess the tripartite definition of knowledge.
Intro: sosas virtue epistemology correct
definition of propsitional knowledge
para 1: JTB - gutter case 1
para 2: JTB no false lemmas criticism of gutter case
response: fake barn county
para 4: Sosa avoids problems bcos not apt!
conclusion: Sosa avoids all problems + correct

Gettier case one
-smith + Jones are interviewing for the same job
-smith hears the interviewer say “I’m going to give Jones the Job”
-Smith also sees Jones count 10 coins from his pocket.
-Smith thus forms the belief that “the man who will get the Job has 10 coins in his pocket”
-But smith gets the Job, not jones
-and by coininsidence smith also has 10 coins in his pocket
Gettier case two
Brown in Barcelona
Smith has evidence that his friend Jones owns a ford. smith believes that jones owns a ford. smith has another friend brown. he has no evidence of mr brown’s whereabouts, but on the strength of his first belief forms a new disunctive belief that jones owns a ford or brown is in barcelona. This new belief is justified as smith has no reason to doubt the first part.
It turns out that jones no longer owns a car but by weird coinsidence brown unbeknown to smith was in barcelona.
JTB + no false lemmas in structure
-strengthens tripartite defintion
it says that james has knowledge of P if:
-P is true
-James believs that P
James belief is justified
James did not interfere that P from anything else.
what is JTB + no false lemmas explained
strengthens tripartite defintion
Adds extra condition to tri defintion. knowledge is JTB + that it has not infered from anything else (a false lemma)
it avoids gettier problem.
what is the fake barn county Goldman (problem)
G’s example:
Henry is driving through the country side in barn county + he looks into a field, and sees what he looks exactly like a barn. He forms the belief “there is a barn in the field”. He is correct that there is a barn in the field, + the thing he is looking at is indeed a barn. However he is unaware that in barn county, may farmers construct fake barns- facades which look like real barns when viewed from the road, but are in fact just two-dimensional pictures. Henry got lucky in that he viewed the only real barns miles around.
