Knowledge As Justified True Belief
Many or most analytic philosophers would wish to be able to hold to what is known as the JTB account of knowledge: the claim that knowledge can be conceptually analyzed as justified true belief — which is to say that the meaning of sentences such as "Smith knows that it rained today" can be given with the following set of necessary and jointly sufficient conditions:
- A subject S knows that a proposition P is true if and only if:
-
- P is true
- S believes that P is true, and
- S is justified in believing that P is true

Famous quotes containing the words knowledge, justified, true and/or belief:
“The improver of natural knowledge absolutely refuses to acknowledge authority, as such. For him, skepticism is the highest of duties; blind faith the one unpardonable sin.”
—Thomas Henry Huxley (1825–95)
“We ourselves are Jews by birth and not Gentile sinners; yet we know that a person is justified not by the works of the law but through faith in Jesus Christ. And we have come to believe in Christ Jesus, so that we might be justified by faith in Christ, and not by doing the works of the law, because no one will be justified by the works of the law.”
—Bible: New Testament, Galatians 2:15-16.
“He who is only a traveler learns things at second-hand and by the halves, and is poor authority. We are most interested when science reports what those men already know practically or instinctively, for that alone is a true humanity, or account of human experience.”
—Henry David Thoreau (1817–1862)
“There is a place where we are always alone with our own mortality, where we must simply have something greater than ourselves to hold onto—God or history or politics or literature or a belief in the healing power of love, or even righteous anger.... A reason to believe, a way to take the world by the throat and insist that there is more to this life than we have ever imagined.”
—Dorothy Allison (b. 1949)
