Whether the eternal law is known to all?

Objections

Objection 1 : It would seem that the eternal law is not known to all. Because, as the Apostle says (1 Cor. 2:11), "the things that are of God no man knoweth, but the Spirit of God." But the eternal law is a type existing in the Divine mind. Therefore it is unknown to all save God alone.
Objection 2 : Further, as Augustine says (De Lib. Arb. i, 6) "the eternal law is that by which it is right that all things should be most orderly." But all do not know how all things are most orderly. Therefore all do not know the eternal law.
Objection 3 : Further, Augustine says (De Vera Relig. xxxi) that "the eternal law is not subject to the judgment of man." But according to Ethic. i, "any man can judge well of what he knows." Therefore the eternal law is not known to us.
