Review of K. Šebela, “Internal negation and sortal quantification”

Abstract

The article proposes a logical analysis of sentences of the form ‘S is non-P’. The author highlights the notion of contrariety as central to his proposal, since he understands internal negation as a contrary-forming kind of negation. This is captured with the the apparatus of sortal quantification, in terms of a restriction of the quantifier’s range.
