 Weinberg (2008) argues that parental responsibilities cannot be transferred in full because certain kinds of intimate responsibilities can only be fulfilled by particular individuals: individuals in the right intimate relationship. For instance, parents cannot transfer the obligation to celebrate their children’s achievements to others by having strangers attend their children’s music recitals or award ceremonies. Weinberg thinks that gamete donors have a responsibility to love their children and that the responsibility to love a particular person is paradigmatic of the kind that cannot be transferred. Consequently, at least some parental responsibilities are not transferable.
