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:
“A knowledge that people live close by is,
I think, enough. And even if only first names are ever exchanged
The people who own them seem rock-true and marvelously self-sufficient.”
—John Ashbery (b. 1927)
“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.
“The second day of Christmas,
My true love sent to me
Two turtle doves,”
—Unknown. The Twelve Days of Christmas (l. 4–6)
“To be faced with what so-and-so’s mother lets him do, or what the teacher said in class today or what all the kids are wearing is to be required to reexamine some part of our belief structure. Each time we rethink our values we reaffirm them or begin to change them. Seen in this way, parenthood affords us an exceptional opportunity for growth.”
—Ruth Davidson Bell (20th century)
