The actions causally derived from randomness in our universe seem random because we inside the system have no Informational view in to the meta-system in which they have some kind of causal logic, but the decision makes sense when you have access to that higher-order logic in the meta-system. The random state of some set of particles in someone's brain that makes them choose one action over another, could be a connective tissue by which the meta-'soul' asserts its control.

It's useless for any kind of pragmatic ethical effort, and really it's just pushing the problem up one level, but it's fun to think about.
