 A related problem is that causal accounts often leave it unclear how causal responsibility generates moral responsibility. Sometimes it appears that the thought is that procreators, by causing a child to exist, have placed it in a needy position and so owe it, as compensation, “procreative costs.” But these costs are arguably not equivalent to the weighty responsibilities of parenthood (Brake 2010). The question is whether, as a result of causal responsibility for their existence, parents merely owe children repair of their needy condition, by fostering survival to adulthood, or whether such “procreative costs” include a richer set of parental responsibilities, such as a duty to love and to make the child “content with his condition” (Prusak 2011b, 67).
