Sometimes it is said that God has libertarian freedom. The argument for this often goes like this:
- God freely chose to create the world.
- The world is not necessary.
- Therefore, God’s free act of creating of the world was not determined.
- Therefore, God has libertarian freedom.
This argument is actually quite popular, but it is invalid. For the sake of the argument, I’ll grant we can validly get to (3). However, the jump to (4) assumes a suppressed premise, something like:
- 3a. If a free act A is not determined, then A is libertarian free.
But that is false. It assumes that indeterminism is sufficient for libertarianism, when it’s actually only necessary for libertarianism. What is needed instead is something like this:
- 3a′. Freedom is incompatible with determinism.
But with this addition, the argument would then assume incompatibilism. (1)–(2) at best get you indeterminism, but what is needed to secure the conclusion that God’s freedom is libertarian is an argument for incompatibilism, not an argument that assumes incompatibilism.
