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
