The Epistemology of Modality

How can we come to know, be justified in believing, or understand, that something is necessary, possible, contingent, essential, or accidental? This is the central question in the epistemology of modality. After some short remarks on the importance of this question for philosophy and for our everyday life, this chapter briefly summarizes Kripke's seminal contribution to the field, discusses two different skeptical challenges in the epistemology of modality, and briefly surveys some of the most discussed contemporary accounts and answers to the central question.
