Hinge Epistemology is a new branch of philosophy inspired by Ludwig Wittgenstein’s view in On Certainty, that 'the questions that we raise, and our doubts, depend on the fact that some propositions are exempt from doubt, are as it were like hinges on which those turn' (OC 341). Hinge Epistemology is rapidly becoming one of the most exciting areas of epistemology and Wittgenstein studies. In connecting these two fields it brings a revived energy to both, opening them up to fresh developments. The essays in this volume extend the subject in terms of both depth and breadth in the following ways: 

(i) Fastening the hinges: In the opening essays of the book, proponents of the three major perspectives on the nature of hinge certainties strengthen their views, often by virtue of response to one another. These are followed by essays presenting new voices and challenges within hinge epistemology.

(ii) Opening the door: The second half of the book explores new applications and directions of hinge epistemology, particularly as it relates to the philosophy of mind, society, ethics, and the history of ideas.
