We argue against Thomson’s view that abortion is permissible even if fetuses have high moral status. Against this, we argue that, because many mothers are morally responsible for their pregnancies, they have a special obligation to assist. Finally, we address an objection according to which many mothers whose pregnancies are not a product of rape are not morally responsible to a sufficient degree, and so an obligation to assist is not generated. This objection assumes that the force of the mother’s (...) right to bodily integrity is not diminished if she is insufficiently morally responsible. We challenge this assumption. Our complete thesis is as follows: If a mother is morally responsible to a sufficient degree, she acquires an obligation to assist. If she is not, the force of her right to bodily integrity may be reduced. (shrink)

Moral responsibility theorists divide over whether facts about holding someone morally responsible are dependent on facts about being morally responsible, or whether the dependence relation runs in the other direction. A novel answer, proposed by Michael McKenna, is that neither side depends on the other. Instead, they are interdependent. Call this the ‘interdependence thesis’. A worry is that the interdependence thesis violates formal principles of metaphysical dependence in terms of ground. This paper analyses and defends the interdependence thesis, interacting with (...) recent work in the metaphysics of grounding. I vindicate the interdependence thesis from the charge that it violates the formal principles of metaphysical grounding. I then pull from recent work in communication theory and apply it to McKenna's ‘conversational theory of moral responsibility’, in order to respond to two new objections. One upshot is that I advance the conversational theory of moral responsibility. (shrink)
