Gettier problems function as challenges to the philosophical tradition of defining knowledge of a proposition as justified true belief in that proposition. The problems are actual or possible situations in which someone has a belief that is both true and well supported by evidence, yet which — according to almost all epistemologists — fails to be knowledge.

Are there JTB epistemologies which reject the knowledge of some Gettier problems, but in which religious experiences still justify belief?
Such is my current worldview that there is no religious experience or numinous feeling that could justify faith in any god.
This is because, in the wake of a slew of discoveries about the unreliability of the brain (such as its propensity for change…

How does Robert Nozick explain the Gettier problem?
Nozick agrees that the Gettier counterexamples to the JTB analysis of knowledge are cases where someone has a JTB but does not know. What is his explanation of what has gone wrong in those cases? Specifically what conditions in Nozick’s account of…

The non-existence of Gettier problems in Indo-Tibetan epistemology
Reading the paper Gettier and Factivity in Indo‐Tibetan Epistemology the author claims at some point early in the paper that
There are two initial problems which make it difficult to compare factive
assessment with true belief and the Gettier…

Isn't a Gettier case just lack of adequate justification?
As I understand it a Gettier case happens when there is a true belief that is justified but only by luck.
Common scenarios include
looking at a broken watch and it just happens to be the time on that watch. You believe it's that time, it's true…

Does the second Gettier case really work?
Why does Brown being in Barcelona have anything to do with Jones owning a Ford?
Surely examples such as "a stopped clock tells the time twice a day", and many other examples people have come up with since first reading Gettier, (such as sheep being…

Gettier Cases seem absurd and unconvincing
Suppose that Smith and Jones have applied for a certain job. And suppose that Smith has strong evidence for the following conjunctive proposition: (d) Jones is the man who will get the job, and Jones has ten coins in his pocket.
Smith's evidence for…

Does Gettier paradox exist when we use deductive reasoning?
Show that 1+1+1=3
1+1+1 = (1 + (1+1)) = (1+3) =3
The mistake in the inner bracket calculation is that I considered 1+1 to be equal 3, and that of the outer bracket is that is that I considered 1 plus 3 to be equal 3 again.
Would the above…

'Counterexamples in Philosophy'
In mathematics there's a type of book, bordering on the textbook but slightly different, that compiles examples to demonstrate the necessity of various conditions on theorems and the correct directions of implication. For example, to show that a…

Can "Gettier problems" be solved by changing Justified, True Belief without introducing a fourth condition?
It seems to me Gettier problems challenge the Justified, True Belief account of knowledge.
As I see it, they can be solved by assuming that knowledge requires something else: a set of propositions Q which are held by the subject and which represent…

Did Gettier's paper have an impact outside epistemology?
Edmund Gettier's paper refuting the Justified True Belief (JTB) account of knowledge has been described as 'landmark' and 'legendary'. I more or less understand how it proved, using counterexamples, that a true belief that's justified isn't the same…

Can "Gettier problems" be resolved by assuming JTB as the formal definition of truth?
What problems arise in responding to Gettier problems with an assertion "the formal definition of knowledge, as justified true belief, does not need to exactly correspond to intuitive notions of knowledge."? As I understand it, the main claims are…

Why does Nozick rely on closest possible world in his tracking theory?
According to the truth-tracking theory of Nozick,
S knows that P iff
(1) P is True,
(2) S believes that P,
(3) If P were not True, S would not believe that P, and
(4) If P were True, S would believe that P
But when explaining the third…

Has no epistemologist noticed the problem with "truth" before Gettier?
According to Wikipedia (indeed not the most trustworthy source, but the SEP article also portraits it this way) the classic belief-justification-truth method of defining knowledge has only been rejected since Gettier-cases. Meaning that, all the way…
