Chosen Topic : Theory of Knowledge
Chosen Theory: Lehrer and Paxson's Defeasibility.
The Value Problem: Why is knowledge more valuable than true belief?  __________________________________________________________________________________________
Is knowledge more valuable than true belief?
According to Lehrer and Paxson's theory of defeasibility, basic knowledge is completely justified true belief and nonbasic knowledge requires something more.
1)basic knowledge is JTB
2)nonbasic knowledge has more value than basic knowledge
3)nonbasic knowledge has more value than JTB
__________________________________________________________________________________________
S has basic knowledge that h if and only if
(i)   h is true
(ii)  S believes that h
(iii) S is completely justified in believing that h
(iv)  The satisfaction of condition (iii) does not depend on any evidence p justifying S in believing that h.
__________________________________________________________________________________________
S has nonbasic knowledge that h IFF
(i) h is true
(ii) S believes that h
(iii*) p completely justifies S in believing that h and no other statement q defeats this justification
where p is that statement which makes S completely justified in believing that h. __________________________________________________________________________________________
A defeater is...
When p completely justifies S in believing that h, p is defeated by q IFF
i) q is true
ii) S is completely justified in believing q to be false
iii) The conjunction of p and q does not completely justify S in believing that h

We can introduce the concept of being more likely to be correct or "Undefeated" in the future.
