Abstract
Construing the instantiation of a universal by a particular in terms of my theory of aspects
resolves the basic mystery of this "non-relational tie", and gives theoretical unity to the
four characteristics of instantiation discerned by Armstrong. Taking aspects as distinct in
a way akin to Scotus's formal distinction, I suggest that instantiation is the sharing of an
aspect by a universal and a particular--a kind of partial identity. This approach allows
me to address Plato's multiple location and One over Many problems, Bradley's problem
concerning the instantiation of relations, and the problem of change.
