Quote from ‘Nomenclature and Divisions of Dyadic Relations’
A dyadic relation proper is either such as can only have place between two subjects of different universes of discourse (as the membership of a natural person in a corporation), or is such as can subsist between two objects of the same universe. A relation of the former description may be termed a referential relation; a relation of the latter description, a rerelation.
