As Henderson notes (2009, 130–131), the envisaged combination of contexualist and invariantist ideas might prove unstable: actual attributors are members of multiple, overlapping communities; information is constantly being shared multilaterally; and so on. Factors such as these are among the considerations cited by Rysiew (2012) in arguing that its having a traditional invariantist semantics might make ‘know’ better suited to fulfilling certain central social roles. (For a reply, see Hannon 2015.) Such claims take us back to considerations of whether EC sits well with the transfer and storage of information (see Section 4.5). More generally, they serve to show that the bearing of certain data upon the semantics of ‘know’ is just as controversial when we’re considering the term’s (or concept’s) social role or function, as when we are considering particular uses of it.
