Abstract: | Michael Dummett has argued that a formal semantics for our language is inadequate unless it can be shown to illuminate to
our actual practice of speaking and understanding. This paper argues that Frege’s account of the semantics of predicate expressions
according to which the reference of a predicate is a concept (a function from objects to truth values) has exactly the required
characteristics. The first part of the paper develops a model for understanding the distinction between objects and concepts
as an ontological distinction. It argues that, ontologically, we can take a Fregean function to be generated by a property
detection device that can register for any object the presence or absence of that property. This provides a direct connection
between the semantics of sentences and the structure of perceptual judgment. The second part of the paper deals with arguments
that have been mounted against the coherence of Frege’s semantics. It argues that some of these are question begging, while
others are correct in so far as Frege’s claim is untenable if we assume that the syntactic categories singular term and predicate
are primary, and the ontological categories are simply projections of these syntactic categories. However, the objections
dissipate once we recognize that an independent ontological characterization of the distinction is available. |
