  The view that everything is a matter of responsibility (and desert) luck obviously flies in the face of our everyday ascriptions of responsibility. Accordingly, this implication of the regression principle is often deployed in a corresponding reductio ad absurdum (Hurley 1993, 183; Hurley 2003; Nozick 1974, 225; Sher 1997, 67–69; Zaitchik 1977, 371–373). However, this reductio is perhaps too hasty. It has been argued that the principle (applied to control) is not simply a matter of “generalization from certain clear cases.” Rather, it is a condition that we “are actually being persuaded” is correct when we apply it to cases “beyond the original set”, where, on reflection, we find that “control is absent” (Nagel 1979, 26–27). If this is right, it seems we need an alternative explanation of why moral responsibility is absent in those cases where control of causes is absent. So, for instance, if we agree that a person who offends, as an adult, as a result of childhood deprivation is not responsible for his action, we need to explain what, here, nullifies responsibility if not lack of control over causes of the agent’s actions. That is, we need to explain why certain kinds of causal background to action threaten control while others do not even if we are dealing with cases with the shared feature that the agent does not control the early parts of those causal backgrounds.
