 Callender and Cohen voice scepticism about there being a solution to this problem and suggest that the distinction between scientific and non-scientific representations is circumstantial (2006: 83): scientific representations are representations that are used or developed by someone who is a scientist. Other authors do not explicitly discuss the representational demarcation problem, but stances similar to Callender and Cohen’s are implicit in any approach that analyses scientific representation alongside other kinds of representation. Elgin (2010), French (2003), Frigg (2006), Hughes (1997), Suárez (2004), and van Fraassen (2008), for instance, all draw parallels between scientific and pictorial representation, which would make little sense if pictorial and scientific representation were categorically different.
