Tripartite definition of knowledge

A revision powerpoint including all points from the new syllabus. Powerpoint includes photos, activities and good explanations of each point. Is an easy read.

3.1.1 What is knowledge?
The distinction between acquaintance knowledge, ability knowledge and propositional knowledge.
The nature of definition and how propositional knowledge may be analysed/defined.
The tripartite view
Propositional knowledge is defined as justified true belief: S knows that p if and only if:

S is justified in believing that p,
p is true and
S believes that p (individually necessary and jointly sufficient conditions)
Issues with the tripartite view including:

the conditions are not individually necessary
the conditions are not sufficient – cases of lucky true beliefs (including Edmund Gettier’s original two counter examples):
responses: alternative post-Gettier analyses/definitions of knowledge including:
strengthen the justification condition (ie infallibilism)
add a ‘no false lemmas’ condition (J+T+B+N)
replace ‘justified’ with ‘reliably formed’ (R+T+B) (ie reliabilism)
replace ‘justified’ with an account of epistemic virtue (V+T+B).
