Single Idea 20226

[filed under theme 13. Knowledge Criteria / A. Justification Problems / 2. Justification Challenges / b. Gettier problem ]

Full Idea

As long as the concept of knowledge closely connects the justification component and the truth component but permits some degree of independence between them, justified true belief will never be sufficient for knowledge.

Gist of Idea

Gettier problems are always possible if justification and truth are not closely linked

A Reaction

Out of context this sounds like an advertisement for externalism. Or maybe it just says we have to live with Gettier threats. Zagzebski has other strategies.


The 13 ideas with the same theme [mere true justified belief doesn't ensure knowledge]:

True belief about the time is not knowledge if I luckily observe a stopped clock at the right moment [Russell]
A true belief is not knowledge if it is reached by bad reasoning [Russell]
True belief is not knowledge when it is deduced from false belief [Russell]
Being a true justified belief is not a sufficient condition for knowledge [Gettier]
For internalists Gettier situations are where internally it is fine, but there is an external mishap [Zagzebski]
Gettier problems are always possible if justification and truth are not closely linked [Zagzebski]
We avoid the Gettier problem if the support for the belief entails its truth [Zagzebski]
Gettier cases arise when good luck cancels out bad luck [Zagzebski]
Gettier says you don't know if you are confused about how it is true [Yablo]
A Gettier case is a belief which is true, and its fallible justification involves some luck [Hetherington]
Gettier and lottery cases seem to involve luck, meaning bad connection of beliefs to facts [Black,T]
In a disjunctive case, the justification comes from one side, and the truth from the other [Vaidya]
Gettier deductive justifications split the justification from the truthmaker [Vaidya]
