Book excerpt: This book examines the question of what parental obligations procreators incur by bringing children into being. Prusak argues that parents, as procreators, have obligations regarding future children that constrain the liberty of would-be parents to do as they wish. Moreover, these obligations go beyond simply respecting a child’s rights. He addresses in turn the ethics of adoption, child support, gamete donation, surrogacy, prenatal genetic enhancement, and public responsibility for children.
