This volume gathers eleven new and three previously published essays on the fertile connection between ethics and epistemology. They examine the following topics: epistemic duty, doxastic voluntarism, the normativity of justification, internalism vs. externalism, truth as the epistemic goal, skepticism and the search for the criteria of justification, virtue epistemology, and understanding as an epistemic value. Among the contributors are Erneat Sosa, Linda Zagzebski, Susan Haack, and Alvin Goldman.
