Quote from ‘Nomenclature and Divisions of Dyadic Relations’


A dyadic relation is a character whose being consists in the logical possibility of a definite fact concerning an ordered pair, or dyad, of subjects; the first of these being termed the relate, the second the correlate; and the relation is said to subsist between the relate and correlate when the fact in whose possibility its being consists actually has place between these objects. The relation, by itself, is, therefore, an ens rationis and mere logical possibility; but its subsistence is of the nature of a fact. When the quality of the fact concerning two objects is considered, without reference to any distinction between these subjects other than that which this fact establishes, and therefore regardless of which of them is relate, which correlate, its possibility is termed by the author a relationship. (It is a useful distinction, but cannot be translated into every language.)
