Nope, I am talking about sets, but using Zadeh's fuzzy set theory where different variables defining the boundary conditions of a set have different membership values for each particular instance. The "sets" become ideal types in the Weberian sense (at least depending on how they are defined). Also, it's not the terms that fall into the sets, although that happens with lower order terms being partial members of upper order terms, but, rather, particular instances or events that fall into an area (basically, a topological manifold).
