2. But to uphold the divine absoluteness, it is also necessary that God be libertarianly free in his production of creatures. For suppose there is something in the divine nature that necessitates God's creation. Then God would depend on the world to be himself and to be fully actual. He would need what is other than himself to actualize himself. This entanglement with the relative would compromise the divine absoluteness. God would need the world as much as the world needs God. Each would require the other to be what it is. (210)
3. So God must be both simple and free to be absolute. But it is very difficult to understand how a simple being could be free in the unconditional 'could have done otherwise' sense. If God is simple, then he is pure act in which case he is devoid of unrealized powers, potentialities or possibilities. To act freely, however is to act in such a way that one (unconditionally) could have done otherwise, which implies unrealized possibilities.
In this post I’m not going to take a general position on divine simplicity. Instead, I’m going to make a narrower point.
It seems to me that this objection suffers from a crude notion of potentiality which conflates different types of potentiality.
i) For instance, we might say a boy is potentially a man. Boyhood is a goal-oriented stage whose telos is manhood.
If a boy doesn't achieve manhood, then he's unfulfilled in that respect. He doesn't become what he was meant to be. He's essentially frustrated. He failed to achieve his natural telos.
ii) Consider another type of potentiality: I could either wear a tie to church or not wear a tie to church.
But surely that's a very different type of potentiality. Whether or not I wear a tie is hardly intrinsic to my nature. I'm not unfulfilled by having that unexemplified possibility. That's not like a process of maturation, or a phase in my self-actualization. I'm not stunted thereby.
iii) To put this another way, whether or not God makes the world (or makes a different world) is irrelevant to his personal fulfillment. He has nothing to gain (or lose) by that action. In that sense, God has no ends–no intrinsic telos to be realized or unrealized. God is goal-oriented, but he's not the beneficiary of what he plans.
