Whether paternal right and right of dominion should be distinguished as special species?

Objections

Objection 1 : It would seem that "paternal right" and "right of dominion" should not be distinguished as special species. For it belongs to justice to render to each one what is his, as Ambrose states (De Offic. i, 24). Now right is the object of justice, as stated above (Article [1]). Therefore right belongs to each one equally; and we ought not to distinguish the rights of fathers and masters as distinct species.
Objection 2 : Further, the law is an expression of what is just, as stated above (Article [1], ad 2). Now a law looks to the common good of a city or kingdom, as stated above (FS, Question [90], Article [2]), but not to the private good of an individual or even of one household. Therefore there is no need for a special right of dominion or paternal right, since the master and the father pertain to a household, as stated in Polit. i, 2.
Objection 3 : Further, there are many other differences of degrees among men, for instance some are soldiers, some are priests, some are princes. Therefore some special kind of right should be allotted to them.
