 The upshot is that there is no way of spelling out the details of this FSC in a way that preserves both the responsibility of the agent and the lack of alternatives. Yet both are need for it to be a successful counterexample. If all FSCs are structurally similar to this one, they are powerless against PAP. (Versions of this “dilemma defense” include Kane 1985: 51; 1996: 142–3, 191–2; Widerker 1995; Ginet 1996; Wyma 1997; cp. Ekstrom 2000: 197 for a similar dilemma; and see Haji &amp; McKenna 2004 for a critical overview. Vihvelin 2000 presents a different dilemma for FSCs, one that nevertheless engages some of issues that will come up below; for an exchange on that alternative dilemma, see Fischer 2008; Vihvelin 2008.)
