Full Idea
Some trope theorists give accounts of particulars. Sets of tropes will not do because they are always abstract, but we might say that particulars are (concrete) mereological wholes of the tropes which they instantiate.
Gist of Idea
Maybe concrete particulars are mereological wholes of abstract particulars

A Reaction
Looks like a non-starter to me. How can abstract entities add up to a mereological whole which is concrete?
