Probabilistic supervenience and agential possibilities

Compatibilist libertarianism proposes a new solution to the problem of an apparent incompatibility of free will and determinism. It drives a wedge between ontological levels and claims that free will is possible as a higher-level phenomenon even if the fundamental physical level is governed by determinism. After highlighting an inconsistency in the current version of compatibilist libertarianism, we discuss how one of its essential metaphysical assumptions (in particular: supervenience) can be modified in order to avoid this problem. Finally, we discuss the pros and cons of pushing the position to the limits in this way.
