27. In saying that only among 'persons' can there come to be rights, and that every 'person' should have rights, I have been careful to explain that I use 'person' in the moral, not merely in the legal, sense. In dealing, then, with such phrases as 'jura personarum' and 'personal rights,' we must keep in view the difference between the legal and ethical sense of the proposition that all rights are personal, or subsist as between persons. In the legal sense, so far as it is true,--and it is so only if 'person' is used in the sense of Roman law,--it is an identical proposition. A person means a subject of rights and nothing more. Legal personality is derived from the possession of right, not _vice versa_. Like other identical propositions, its use is to bring out and emphasise in the predicate what is included in the understood connotation of the subject; to remind us that when we speak of rights we imply the existence of parties, in English phraseology, capable of suing and being sued. In the ethical sense, it means that rights are derived from the possession of personality as = a rational will (i.e. the capacity which man possesses of being determined to action by the conception of such a perfection of his being as involves the perfection of a society in which he lives), in the sense _(a)_ that only among beings possessed of rational will can there come to be rights, _(b)_ that they fulfil their idea, or are justifiable, or such rights as should be rights, only as contributing to the realisation of a rational will. It is important to bear this distinction in mind in order that the proposition in its ethical sense, which can stand on its own merits, may not derive apparent confirmation from a juristic truism.
