Abstract

Harry Frankfurt's well-known counterexample to the principle of alternate possibilities (PAP) has recently come under attack by those who argue that the success of that sort of counterexample depends on the falsity of incompatibilism. In response, I argue that, given one controversial assumption, there are Frankfurt-style counterexamples to PAP that don't take the falsity of incompatibilism for granted. The controversial assumption is the Molinist one that something like middle knowledge is possible. I then show how the falsity of PAP causes some trouble for the Free Will Defense standardly offered in response to atheistic arguments from evil.
