 It should be noted that Zalta’s comprehension principle for abstract objects is unrestricted and so constitutes a plenitude principle. This allows the theory to provide objects for arbitrary mathematical theories. Where \(\tau\) is a term of mathematical theory \(T\), the comprehension principle yields a unique object that encodes all and only the properties \(F\) that are attributed to \(\tau\) in \(T\) (Linsky &amp; Zalta 1995, Nodelman &amp; Zalta  2014).[12]  Zalta’s theory therefore offers significant explanatory power, for it has multiple applications and advances solutions to a wide range of puzzles in different fields of  philosophy.[13]
