Gail Stine was an analytic epistemologist best known for her influential 1976 paper 'Skepticism, Relevant Alternatives, and Deductive Closure,' which helped establish the relevant alternatives framework in contemporary epistemology. She argued that knowledge attributions are context-sensitive and that skeptical arguments fail because they invoke alternatives that are not relevant in ordinary epistemic contexts. Her work was foundational in shaping debates about epistemic closure and the structure of skeptical reasoning.

Argued that epistemic closure principles do not straightforwardly support radical skepticism
Contributed to the analysis of context-dependence in knowledge attributions, anticipating epistemic contextualism
Her 1976 paper in Philosophical Studies remains a key reference in debates on skepticism and closure
