ABSTRACT
The great interest engendered by Harry Frankfurt’s counterfactual intervener (Cl) scenario is based upon the way it purports to undercut the incompatibilist case by challenging the second inference, to wit, from the absence of alternative possibilities to the absence of freedom and/or moral responsibility. The Cl-scenario has been challenged not only by compatibilists who insist that freedom requires alternative possibilities (‘classical compatibilists’), but also by those who deny that the scenario is possible if Jones really has libertarian-style freedom. Overdetermination is indeed a possibility; but here, in an effort to salvage intentional explanations of behavior alongside neurophysiological ones, the author are looking at systematic overdetermination and that, as others have said, is extremely unlikely. Overdetermination may take place; but unless occurrences are fortuitous, it would be a mystery as to why they occur in a systematic fashion.
