This collection showcases the most influential published essays by philosopher Linda Trinkaus Zagzebski. One of the most distinguished thinkers working in epistemology today, particularly where the theory of knowledge meets ethics and the philosophy of religion, Zagzebski is well-known for broadening epistemology and refocusing it on epistemic virtue and epistemic value. Her work has greatly influenced the trajectory of contemporary epistemology, opening up new fields in analytic epistemology. The papers collected here are organized into six sections to underline the scope of her impact on six key subject areas of epistemology: (1) knowledge and understanding, (2) intellectual virtue, (3) epistemic value, (4) virtue in religious epistemology, (5) intellectual autonomy and authority, and (6) skepticism and the Gettier problem.
