Abstract
Josef Seifert and John F. Crosby are the two main proponents of applied material value-ethics. Both reject all forms of suicide and abortion. Seifert also explicitly rejects euthanasia, torture, destructive stem-cell research, genetic enhancement, in vitro fertilization, and contraception. Crosby explicitly rejects spousal in vitro fertilization and spousal contraception. In this essay I examine whether their case should be regarded as convincing. Against Seifert, and possibly also against Crosby, I show why it definitely should not.
