Knowledge is firm, stable belief corresponding to reality.
Correspondence excludes false belief; firm conviction distinguishes knowledge from indecision; and stability distinguishes warranted knowledge from a merely accidental correct guess or unsupported imitation liable to collapse.
Someone who guesses an answer correctly does not thereby necessarily possess certain knowledge. These qualifications clarify the classical discussion of knowledge, doubt, conjecture and imitation; finer accounts differ across theologians.
