Feature-placing sentences and the canonical scheme

Abstract

Feature-placing sentences are often confused with the general sentences in the canonical predicate calculus. The confusion is largely caused by their perceived commonality that both lack the subject-predicate form. In this paper, I offer some clarification of the fundamental differences between the two: the general sentences of the canonical predicate calculus contain predicates and variables which take individual objects as their values, and it is the sense of predication implied by the existence of predicates in these general sentences that is completely absent in feature-placing sentences.
