 Before turning to our second compatibilist model, it is worth noting that it would be a mistake to think that Fischer and Ravizza’s account is a sourcehood account to the exclusion of the ability to do otherwise in any sense. As we have just seen, Fischer and Ravizza place clear modal requirements on mechanisms that issue in actions with respect to which agents are free and morally responsible. Indeed, this should be clear from the very idea of reasons-responsiveness. Whether one is responsive depends not merely on how one does respond, but also on how one would respond. Thus, any account that makes reasons-responsiveness an essential condition of free will is an account that makes the ability to do otherwise, in some sense, necessary for free will (Fischer [2018] concedes this point, though, as noted above, the reader should consider Sartorio [2016] as a potential counterexample to this claim).
