The puzzle(S) of frankfurt-style omission cases

Can we be morally responsible for omitting to do things that we were not able to do? Although at first sight it appears that we cannot, some have argued that Frankfurt-style omission cases show otherwise. This generates a puzzle that resists an easy solution. This chapter argues that solving this puzzle is like opening a can of worms, in that identifying the right solution to it generates other even more intricate and more interesting puzzles. The chapter then offers some tentative solutions to the puzzles, old and new, but its main goal is to draw attention to the problems, and to uncover the kinds of elements that we would need to solve them.
