Das Potenzialitätsargument (PA) ist das wohl wichtigste Argument der Gegner der verbrauchenden Embryonenforschung und des Schwangerschaftsabbruchs. Weil schon der frühe Embryo eine potenzielle Person sei, so das Argument, besitze er bereits den moralischen Status einer Person. Mit der Möglichkeit, aus differenzierten somatischen Zellen „ethisch unproblematische“ induzierte pluripotente Stammzellen (iPS-Zellen) zu gewinnen, schien diese PA-Problematik zumindest für die Forschung umgangen. Indessen zeigen neuere wissenschaftliche Erkenntnisse, dass auch aus pluripotenten Zellen neue Organismen erwachsen können. Der Beitrag argumentiert dafür, dass nach der Logik (...) von PA nicht nur iPS-Zellen, sondern auch die somatischen Zellen, aus denen diese entstehen, als potenzielle Personen mit Würde und Lebensrecht anzusehen wären. Aufgrund dieser Implikationen ist PA auch nicht als Argument für ein Lebensrecht von Embryonen geeignet. (shrink)

Debates on the moral status of human embryos have been highly and continuously controversial. For many, these controversies have turned into a fruitless scholastical endeavor. However, recent developments and insights in cellular biology have cast further doubt on one of the core points of dissent: the argument from potentiality. In this article we want to show in a nonscholastical way why this argument cannot possibly survive. Getting once more into the intricacies of status debates is a must in our eyes. (...) Not merely intellectual coherence but the standing and self-understanding of current stem cell research might profit from finally taking leave of the argument from potentiality. (shrink)

This paper explores how current United States policies for funding nonreproductive cloning are justified and argues against that justification. I show that a common conceptual framework underlies the national prohibition on the use of public funds for cloning research, which I call the simple argument. This argument rests on two premises: that research harming human embryos is unethical and that embryos produced via fertilization are identical to those produced via cloning. In response to the simple argument, I challenge the latter (...) premise. I demonstrate there are important ontological differences between human embryos (produced via fertilization) and clone embryos (produced via cloning). After considering the implications my argument has for the morality of publicly funding cloning for potential therapeutic purposes and potential responses to my position, I conclude that such funding is not only ethically permissible, but also humane national policy.

The question of how society should deal with social conflicts arising from cultural differences persists. Should we adopt an exclusivist approach by excluding reasons based on specific cultural traditions (culture-based reasons) from public debates about social policy, especially because these reasons do not appeal to the public at large? Or should we resort to an inclusivist approach by including reasons based on cultural traditions in public debate to give recognition to the diverse cultural identities of those who practice these traditions? (...) While these two approaches assign different roles to cultural traditions in public debate, both seem to welcome compromise between conflicting parties. This paper reviews contending normative approaches for dealing with conflicts in multicultural societies and explores the place of culture-based reasons in public debates designed to resolve conflicts.
