A complex and historically rich account of scepticismMaking a sharp break with dominant contemporary readings of David Hume's scepticism Peter S. Fosl offers an original and radical interpretation of Hume as a thoroughgoing sceptic on epistemological, metaphysical and doxastic grounds. He does this by first situating Hume's thought historically in the sceptical tradition and goes on to interpret the conceptual apparatus of his work including the Treatise, Enquiries, Essays, History, Dialogues and letters. This significant contribution to Hume scholarship advances both historical and logical reasons for the conclusion that Hume is a thoroughgoing radical sceptic.
