Abstract
Confronted with the great variety one can find today in the work of those often labelled (either by themselves or by
others) as “relationalists”, “naïve realists” or “disjunctivists”, one could be excused for thinking that relationalism has
no common core, but is instead a constellation of views, which at best bear a kind of family resemblance to each
other. We believe that this impression would be inaccurate. Relationalism is best thought of not as a constellation of
loosely interrelated views, but as a single wellspring of views, which has both a common core, and a variety of versions
which differ from each other along two central axes of variation. In the first half of this introduction, we articulate
this structure of relationalist views by constructing a common logical space for them. In the introduction’s second
part, we use this logical space to introduce the various contributions this volume collects.
