 Other compatibilists, most notably, John Martin Fischer (1994), and Fischer and Mark Ravizza (1998) (see section 5.5 below), have appealed to similar restrictions. But in doing so, they only mean to explain the nature of the freedom or control exhibited in how the agent did act—that is, what Fischer has termed her guidance control. In striking contrast to how the new dispositionalists reason, they do not think they are thereby entitled to claim that an agent in a Frankfurt example is free to do otherwise. So it is possible that what the new dispositionalists have identified with the pertinent counterfactuals they fix upon is not the freedom to do otherwise, but instead, a freedom located in what an agent does do (which is a matter of guidance control, not regulative control). This, at least, is how compatibilists like Fischer and Ravizza would reason. [For a lively debate over just this issue, see the exchange between Fischer (2008) and Vihvelin (2008).]
