Abstract

Consider the following sentence schemata: (1) The proposition that P is F; (2) The property of being Q is F; (3) The relation of being R is F, where `P' is a schematic letter for a sentence, `Q' and `F' are schematic letters for a nonrelational predicate, and `R' is a schematic letter for a relational predicate. For example, if we substitute `Snow is white' for `P', `famous' for `F' in (1), `round' for `Q', `instantiated' for `F' in (2), `a father of' for `R', and `asymmetric' for `F' in (3), then we obtain the following particular sentences.
