Thanks largely to Edward Craig (1990), the role of ‘know(s)’ (or the corresponding concept) has gotten attention recently—see, e.g., several of the essays in Brown and Gerken (2012). Some writers have suggested theories thereof very much in the spirit of the assurance view—e.g., Kappel (2010), Kelp (2011), and Rysiew (2012).
