These two counter-examples depend on two principles, poverty and rational deductive principles. In degeneration, the reason does not need the truth; and a reasonable reasoning principle requires Q if P has reason to believe the proposition. That means that S has reason to believe Q. Now, there is a wrong proposition, P, S for just reason, and Q is the truth, but not because S supports P inference.
In the field of epistemology, the Gutieres problem is a groundbreaking philosophical issue about understanding descriptive knowledge. Thanks to the American philosopher Edmund Getier, the counteretype counter example (called "Getty Case") is challenging the long-standing knowledge of reasonable beliefs (JTB). The JTB account considers knowledge to be equivalent to a reasonable truth belief and knows the claim if the claim meets all three conditions (reason, truth, and belief). Gattier tried to explain that in an article entitled "Proving Knowledge of Truth" on page 3 of 1963, using two counter-examples individuals can have legitimate true beliefs about assertions . The reason for this belief is reasonable, so I can not even know it, but I can see that it is wrong.
In the epistemology, Gettier's counterexample is two scenarios entitled "Providing the Knowledge of Truth" published by Edumnd Gettier in 1963, which assumes a mistake in the definition of previously accepted knowledge . Therefore, the problem caused by these counterexamples is called the Gettier problem. In the first example, Gaitir assumed two people, Smith and Jones applied for work. We think that there is a reason for Smith to believe that Jones gets a job. Evidence is high enough, and Smith has reason to believe it. "Perhaps the president assured him that Jones would eventually be selected."
Other epistemologists accepted Gattier's conclusion. Therefore, their answer to the Gettier problem included an attempt to find alternative knowledge analysis. They have been trying to discover and agree as the beginning, as a concept of truth or belief, or as a reason why it was admitted as legitimate. For Gettier's example, the JTB (reasonable true belief) may still be satisfactorily defined as having problems, so the truth, belief and proof are not satisfactorily defined. Gattier, a professor at the University of Massachusetts Amherst, was also interested in the logic of the Finnish philosopher Hintikka of Boston University who published "Knowledge and Faith" in 1962.
