Whether the reason of any man is competent to make laws?

Objections

Objection 1 : It would seem that the reason of any man is competent to make laws. For the Apostle says (Rm. 2:14) that "when the Gentiles, who have not the law, do by nature those things that are of the law . . . they are a law to themselves." Now he says this of all in general. Therefore anyone can make a law for himself.
Objection 2 : Further, as the Philosopher says (Ethic. ii, 1), "the intention of the lawgiver is to lead men to virtue." But every man can lead another to virtue. Therefore the reason of any man is competent to make laws.
Objection 3 : Further, just as the sovereign of a state governs the state, so every father of a family governs his household. But the sovereign of a state can make laws for the state. Therefore every father of a family can make laws for his household.
