Each of these three conditions (truth, belief, and justification) is necessary for knowledge, and altogether they are jointly sufficient for having knowledge. As a counter to JTB, Edmund Gettier posed a serious challenge when he introduced the Gettier problem. The Gettier problems are cases of situations in which a person has a justified true belief that fails to be knowledge. Lets look at one case.

Smith and Jones both applied for a job. The company president told Smith that Jones would get the job, and Smith had counted ten coins in Jones’s pocket just prior. Smith seems to have strong evidence to believe that Jones is the man who will get the job and Jones has ten coins in his pocket.

However, Smith…
