Abstract
In Building Better Beings, Vargas develops and defends a naturalistic account of responsibility, whereby responsible agents must possess a feasibly situated capacity to detect and respond to moral considerations. As a preliminary step, he also offers a substantive account of how we might justify our practices of holding responsible—viz., by appeal to their efficacy in fostering a ‘valuable form of agency’ across the community at large, a form of agency that precisely encompasses sensitivity to moral considerations. But how do these accounts relate to one another? Though I find much that is appealing in Vargas’s general approach, I challenge his insistence that these accounts should be treated as ‘conceptually independent’, arguing that this generates an objectionable “justification gap”: on his analysis, someone could remain an appropriate target of our responsibility practices and yet fail to be a morally responsible agent. In closing, I offer a potential solution to this problem, though it means re-visioning how the account of moral responsibility is conceptually tied to the justification of our responsibility practices
