A Partial Look at Moderate Realism

  • Bo R. Meinertsen
Part of the Philosophical Studies Series book series (PSSP, volume 136)


In this chapter, I shall present, develop and evaluate the ontology of Donald Mertz, which he calls moderate realism, based on a selection of his work (1996, 2001, 2002, 2006). The central notion in moderate realism is that of an instance of a relation, a ‘relation instance’ (what Mertz occasionally calls a ‘unit attribute’).
