Indeterminism and Obligation

The obligation dilemma’s indeterministic horn, whose primary constituent is the luck objection, is introduced in this chapter. This is the objection that indeterministically caused actions are too luck-infected to be obligations. Two versions of this objection are discussed. On the No Explanation Version, if an agent indeterministically decides to do one thing rather than another, then there is no detailed causal account of her decision. Since the control free decision requires is causal, her deciding to do what she does is not free. On the Pure Luck Version, if an agent does something, which she refrains from doing in another possible world with the same past and laws, and there is nothing about her powers, capacities, states of mind, moral character, and the like that explains this cross-world difference, then this difference is just a matter of freedom-undermining luck.
