What is the Gettier problem?Show answer
In a three-page paper in 1963, Edmund Gettier presented cases where all three JTB conditions are met yet we would not say the person knows, because the belief is true by luck. A standard example: Smith has strong evidence that Jones will get a job and that Jones has ten coins in his pocket, so Smith infers "the person who gets the job has ten coins." In fact Smith himself gets the job, and Smith happens to have ten coins. Smith's belief is true, believed and justified, yet it is true only by coincidence, so it is not knowledge.
