^{page 57 note 1} This isolation of eternal objects in the realm of possibility is due to the fact that their relations to each other in this realm,—what has been called their ‘relational’ essence,—do not in any way effect their individual essences. In the realm of possibility the relational essences of eternal objects merely constitute a uniform scheme of relationships which is shared in common by all the eternal objects, so far as the status of each permits. Each eternal object stands internally in all its possible relationships, and by so doing constitutes a pervasive uniform scheme. Accordingly the relationships subsisting in the realm of possibility have nothing to do with the individual essence of eternal objects. They involve any eternal objects as relata only. “The eternal objects are isolated because their relationships as possibilities are expressible without reference to their respective individual essences.” (Science and the Modern World, p. 230.)
