Whether abstract essential names can stand for the person?

Objections

Objection 1 : It would seem that abstract essential names can stand for the person, so that this proposition is true, "Essence begets essence." For Augustine says (De Trin. vii, i, 2): "The Father and the Son are one Wisdom, because they are one essence; and taken singly Wisdom is from Wisdom, as essence from essence."
Objection 2 : Further, generation or corruption in ourselves implies generation or corruption of what is within us. But the Son is generated. Therefore since the divine essence is in the Son, it seems that the divine essence is generated.
Objection 3 : Further, God and the divine essence are the same, as is clear from what is above explained (Question [3], Article [3]). But, as was shown, it is true to say that "God begets God." Therefore this is also true: "Essence begets essence."
Objection 4 : Further, a predicate can stand for that of which it is predicated. But the Father is the divine essence; therefore essence can stand for the person of the Father. Thus the essence begets.
Objection 5 : Further, the essence is "a thing begetting," because the essence is the Father who is begetting. Therefore if the essence is not begetting, the essence will be "a thing begetting," and "not begetting": which cannot be.
Objection 6 : Further, Augustine says (De Trin. iv, 20): "The Father is the principle of the whole Godhead." But He is principle only by begetting or spirating. Therefore the Father begets or spirates the Godhead.
