Quote from ‘Nomenclature and Divisions of Dyadic Relations’
A rerelation may either be such as can only subsist between characters or between laws (such as the relation of “essentially depending upon”), or it may be such as can subsist between two existent individual objects. In the former case, it may be termed a modal relation (not a good term), in the latter case an existential relation. The author’s writings on the logic of relations were substantially restricted to existential relations; and the same restriction will be continued in the body of what here follows.
