What does "be true of" mean in the following context?
There is a debate in the literature on properties between the abundant conception of properties (, according to which there is a property corresponding to every natural language predicate and, more generally, every class of individuals,) and the sparse conception of properties ( , according to which a predicate expresses a property only if the objects that predicate is true of resemble one another in an intrinsic way ) .
p.s. The above sentence is quite long, so I get the structure across with brackets. Please feel free to point out if I make any errors.
