A number of philosophers maintain that the destruction of an embryo in the first 2 weeks after fertilization is not morally problematic as it is metaphysically impossible for any human organism to then have existed. We contend that the typical adult human organism was once a zygote so there is no metaphysical shortcut to justify early abortion. We show that five arguments against human organisms ever having been zygotes fail. All of the arguments have to do with one variant or (...) another of the zygote or early embryo dividing. They do not provide any reason to believe that since some adult organisms are not identical to zygotes due to earlier divisions, none could have been. (shrink)

In After God: Morality & Bioethics in a Secular Age, Professor H. Tristram Engelhardt, Jr. argues that the now dominant intellectual culture of the West actively shuns any transcendent point of orientation, such as an appeal to God or to a God’s eye perspective on reality. Instead, it seeks to frame its understanding of reality and morality, and thus its bioethics, without reference to any foundation outside of particular human concerns. This article explores the implications of living in a secular (...) culture that eschews any appeal to a fully objective perspective on reality. Drawing on Engelhardt’s analysis, it argues that absent access to a binding moral standpoint that is not already conditioned by a particular society, culture, or place in history, all moral and bioethical commitments are merely contingent, subject to particular human interests, aesthetic inclinations, personal intuitions, idiosyncratic choices, and political objectives.
