Justified and true belief as necessary conditions for knowledge

This would be a problem for her, because she is relying upon that evidence in her attempt to gain knowledge, and because knowledge is itself always true. But even if the Knowing Luckily Proposal agrees that, inevitably, at least most knowledge will be present in comparatively normal ways, the proposal will deny that this entails the impossibility of there ever being at least some knowledge which is present more luckily.

For example, if reliability could suitably be indexed to the subject's environment, reliabilists could say that Henry's belief is not justified because in his environment, vision is not reliable when it comes to discerning barns from barn-facades.

That is, if one has any justified beliefs, one of these four possibilities must describe the relationships between those beliefs. Propositional knowledge, then, can be called knowledge-that; statements of propositional knowledge or the lack thereof are properly expressed using "that"-clauses, such as "He knows that Houston is in Texas," or "She does not know that the square root of 81 is 9.

Since E is an external factor, this need have no impact whatsoever on how anything appears to the subject. Compared with perception, introspection appears to have a special status.

Gettier problem

It could be argued that, in one's own personal experiences with testimonial sources, one has accumulated a long track record that can be taken as a sign of reliability. The truth lies probably, in this case, somewhere in the middle; but it will be seen how careful we have to be in accepting statements about Luther, however comment may be and will be contradicted.

One of the outstanding reasons why Luther has been able to obtain such an unparalleled popularity in Germany is that the average German feels completely at ease with Luther, much more than with any other great figure of history or the Bible.

Gettier problem

Conceptual possibilities still abound. It is conceivable that we might, without ceasing to be men, go there and verify his statement; it can be tested by the witness of his companions, and there is adequate ground for supposing that he knows the truth of what he is saying. Those proposals accept the usual interpretation of each Gettier case as containing a justified true belief which fails to be knowledge.

A proponent of such a view is called an externalist. But partly, too, that recurrent centrality reflects the way in which, epistemologists have often assumed, responding adequately to Gettier cases requires the use of a paradigm example of a method that has long been central to analytic philosophy.

This last question is unfortunately a very actual and practical one even to us at this day and in this country. When he has a thundering headache, he wonders whether this is due to over-drinking or to the Devil.

Phenomenal Conservatism

A reliability coherentist might make an analogous point. Must all knowledge that p be, in effect, normal knowledge that p — being of a normal quality as knowledge that p. Even though there was some chance that my belief might have been false, there was a sufficient basis for that belief for it to constitute knowledge.

It is important to bear in mind that JTB, as presented here, is a generic analysis. Criticizes phenomenal conservatism and related views using the tainted source objection. Still the belief may be kept up in the tribe that propitiation has been effected in this way; and in a later generation it will be all the easier for another medicine-man to persuade them to a similar act.

So as we might also sayit could be to know, albeit luckily so. But suppose that, as it happens, he does not form it. InEdmund Gettier published two logical counterexamples to knowledge defined as justified true belief. His counterexamples were true, but not for the reasons cited as the evidence for justification.


So the result is a justified false belief, or perhaps simply not knowledge. The conditions postulated in Gettier-type examples are extraordinarily unlikely to occur, but the mere possibility.

in mind, I shal1 now present two cases in which the conditions stated in (a) are true for some proposition, though it is at the same time false that the person. According to the Bible, God killed or authorized the killings of up to 25 million people.

This is the God of which Jesus was an integral part. About the Text of the printed book.

Is Justified True Belief Knowledge? Edmund L. Gettier. Various attempts have been made in recent years to state necessary and sufficient conditions for someone's knowing a given proposition.
