 On the other side of the debate is the voluntarist account of parental obligations, according to which one comes to have parental obligations only by voluntarily accepting such obligations (see Brake for a defense of this view, and Prusak for critique of Brake). Of course, any such view owes us an account of what would count as voluntary assumption of parental obligations. Certain accounts of what counts as voluntary assumption – i.e., ones that count engaging in procreative sexual activity as voluntary assumption of parental obligations – could cause the voluntarist view to collapse back into the causal account. Clearly, getting the appropriate account of causation – if we accept the causal view – and of voluntary assumption – if we accept the voluntarist view – is important if we are to apply these views to issues such as abortion, child support, surrogate motherhood, and new reproductive technologies.
