Fortunately, it isn't.  You can treat morphs as the Views in MVC.  If
you have a Person that is both displayed on its own and is embedded in
an Institution, treat the Person and Institution as Models.  Create
one morph to represent each view of the Person and Institution; in
this case, two morphs representing the Person, and one for the
Institution.
