Many think it is plausible that agents enjoy freedom and responsibility with respect to their actions in virtue of being reasons-responsive. Extant accounts spell out reasons-responsiveness (RR) as a general modal property. The agent is responsive to reasons for and against ϕ-ing, according to this idea, if they ϕ in accordance with the balance of reasons in a suitable proportion of possible situations. This paper argues that freedom and responsibility are not grounded in such modal properties on the basis of (...) a phenomenon I call ‘rational blind spots’. Agents have highly specific local blockages (or openings) that prevent them from seeing or reacting for a particular type of reason. When these blind spots are triggered, agents fail to be responsive to reasons in the sense relevant to freedom and responsibility. Thus, we judge that they are not free and responsible. But bind spots don’t remove the agent’s possession of general modal RR properties. Thus, extant accounts of reasons-responsiveness render the incorrect result that the agents in these cases remain responsible because they remain responsive to reasons in a general sense. (shrink)
