Sider’s Third Realm

Jonah P. B. Goldwater
Published Online: 2014-02-01 | DOI: https://doi.org/10.1515/mp-2014-0007


Sider (2011; Writing the Book of the World. Oxford: Oxford University Press) argues it is not only predicates that carve reality at its joints, but expressions of any logical or grammatical category – including quantifiers, operators, and sentential connectives. Even so, he denies these expressions pick out entities in the world; instead, they only represent the world’s “structure”. I argue that this distinction is not viable, and that Sider’s ambitious programme requires an exotic ontology – and even a Fregean “third realm” – of logical entities.

Keywords: ontological commitment; joint-carving; logical realism; Sider
