The problem of luck is advanced and defended against libertarian theories of responsibility-enabling ability. An outline of an account of ability is articulated to explore some features of the sort of ability moral responsibility requires. The account vindicates the luck objection and suggests a novel puzzle: Libertarianism is structurally barred from answering the problem of luck because responsibility requires, but inherently lacks, an explanation from reason states to actions that preserves reliability of connection between responsibility-grounding reasons-sensitivity and action.

Frankfurt examples invite controversy over whether the pertinent agent in these examples lacks the specific ability to do otherwise, and whether what she does can be obligatory or permissible. We develop an account of ability that implies that this agent does not have the specific ability to refrain from performing the germane action. The account also undergirds a view of obligation that entails that it is morally required or prohibited for an agent to perform an action only if she has (...) the specific ability to do, and to do otherwise than, perform it. Therefore, in Frankfurt examples, it is neither obligatory nor impermissible for the relevant agent to do what she does. (shrink)

Deontic modals are the topic of my dissertation. All deontic modals, yes, but justification in particular, and epistemic justification even more specifically. Deontic modals operate upon performances—they appraise performances. Positively appraised, a performance is appropriate, decent, justifiable, right, permissible, or proper; negatively appraised, inappropriate, indecent, unjustifiable, wrong, impermissible, or improper. Belief and knowledge and performances in exactly the same sense that action and intention are performances: all are products of powers that are in some sense responsive to reasons. The principal (...) difference is the direction of fit between mind and world. Knowledge and belief the product of cognitive powers aimed at adapting mind to world, action and intention the product of conative powers aimed at adapting world to mind. All are normatively evaluable and the characteristic normative appraisal of each is deontic. Epistemology, ethics, and rational choice all investigate the nature of deontic modals, differing only insofar as the central aims are epistemic, moral, or prudential in nature. In this sense, the general theory of deontic modals is the parent to epistemology, ethics, and rational choice. My project is to develop and defend a schematic theory of justification. I achieve this end by developing and defending a general theory of deontic modalities. Riffing on two pithy turns of phrase, the deontic theory may be tersely sloganized: value first and one must do the best one can. It is a teleological theory that defines all deontic concepts from the theoretically foundational notions of ability and value. Roughly, a belief is epistemically justifiable if, and only if, it is part of an epistemically optimific belief set the agent is able to have. Roughly, an act is morally justifiably if, and only if, it is part of a morally optimific action set the agent is able to perform. My pet interest is in the former. The resultant framework is enormously fruitful, especially in epistemology. (shrink)
