 Debates in meta-ontology (analytic ontology) over the last twenty years have sparked renewed interest in realism. They have also seen a marked shift in how realism, i.e. ontological realism, is understood. “The central question of metaontology”, Theodore Sider, a prominent ontological realist, contends, “is that of whether there are many equally good quantifier meanings, or whether there is a single best quantifier meaning.” [Sider 2009, p.397]. Where Sider argues for a single best quantifier meaning, Eli Hirsch believes there are a multiplicity of possible quantifier meanings that are equally good, a thesis he calls Quantifier Variance. This meaning-theoretic focus is something  new.[10]
