 Having reviewed some general features of TE, and some of the major forms and themes of NE, we will next consider some important and influential recent versions of NE, using the above features and categories to clarify and facilitate discussion. This survey will center on recent epistemological developments. However, it bears emphasizing once again that NE per se is not itself a recent phenomenon: as briefly explained in the next (sub)section, various themes within NE are as much a part of our epistemological inheritance as are the usual features of TE.
