In “The Inescapability of Gettier Problems,” Linda Zagzebski provides a specific Gettier case to Plantinga’s proper function theory of knowledge. However, her objection fails to understand Plantinga’s cognitive environment criterion. Specifically, a cognitive environment must be assessed alongside the faculties being used in the formation a belief. Zagzebski’s example is then adapted accordingly. This paper ends with a dilemma: either Plantinga’s theory adopts a dangerously strong condition for warrant, or admits that it cannot escape Gettier cases.
