The Gettier problem is a fundamental challenge to the classical definition of knowledge as justified true belief (JTB). It demonstrates, through two concise thought experiments, that a person can have a belief that is both justified and true, yet still lack knowledge, because the truth is a matter of luck or accident. This refutation, advanced by Edmund Gettier in 1963, forced philosophy to search for a fourth condition that could turn true belief into genuine knowledge.
