 Even if these reasons-responsive and identification compatibilist accounts of sourcehood might successfully side-step the Consequence Argument, they must come to grips with a second incompatibilist argument: the Manipulation Argument. The general problem raised by this line of argument is that whatever proposed compatibilist conditions for an agent \(S\)’s being free with respect to, and morally responsible for, some action \(\phi\), it will seem that agents can be manipulated into satisfying these conditions with respect to \(\phi\) and, yet, precisely because they are manipulated into satisfying these conditions, their freedom and responsibility seem undermined. The two most influential forms of the Manipulation Argument are Pereboom’s Four-case Argument (2001, ch. 4; 2014, ch. 4) and Mele’s Zygote Argument (2006, ch. 7. See Todd 2010, 2012 for developments of Mele’s argument). As the structure of Mele’s version is simpler, we will focus on it.
