Sosa on scepticism and the background

Sosa’s influential work on virtue epistemology includes an intriguing proposal about background commitments, which he in turn relates to the Wittgensteinian notion of a hinge commitment. A critique is offered of Sosa’s proposal, particularly with regard to how he aims to apply it to the problem of radical scepticism. In light of this critique, an alternative conception of hinge commitments is offered that enables them to play a very different role in our treatment of radical scepticism.
