Predication Sortalism

  • Max A. Freund
Part of the Synthese Library book series (SYLI, volume 408)


The focus of this chapter is on predication sortalism, that is, the view that exercise of predication necessarily requires sortal concepts. We distinguish two interpretation of this view; one we call radical and the other moderate predication sortalism. For each of these interpretations a semantic system is characterized. Both semantics are for the bidimensional formal language of Chap.  3 and provide a non-standard interpretation of predication. We state a formal system for moderate predication sortalism and show the system to be sound and complete, with respect to the semantics for moderate predication sortalism. We also indicate how to formulate a formal system for radical predication sortalism as well as show its soundness and completeness.
