Abstract
According to the TDT, no singular propositions about an individual and no "thisnesses" of individuals exist prior to the existence of the indiviĀdual in question, where a thisness "is the property of being x, or of being identical with x" and a "singular proposition about an individual x is a proposition that involves or refers to x directly, perhaps by having x or the thisness of x as a constituent, and not merely by way of x's qualitative properties or relations to other individuals" (p. 315) The support for this position comes from two sources, according to Adams.
