O. 156, That “every man that is born, by his very birth, becomes a subject to him that begets him,” this necessarily follows, viz. That a man by his birth cannot become a subject to his brother, who did not beget him; unless it can be supposed that a man by the very same title can come to be under the “natural and absolute dominion” of two different men at once; or it be sense to say, that a man by birth is under the natural dominion of his father, only because he begat him, and a man by birth also is under the natural dominion of his eldest brother, though he did not beget him.
