Some scientists have reported what they regard as evidence of indeterministic brain processes that influence behavior (Brembs 2011, Maye et al. 2007). How do these reports bear on the positive side of libertarianism about free will? That is an approximation of my guiding question in this article. I make the question more precise in section 1, in light of some conceptual and scientific background. In the remainder of the article, I seek—and eventually offer—an answer. Topics dis-cussed along the way include (...) control, Frankfurt-style cases, and whether event-causal libertarianism is an uninhabitable half-way house between compatibilism and agent-causal libertarianism.
