This essay briefly describes a few of the problems associated with using personhood language to defend the right to life of the pre‐implantation embryo. Arguing that an immaterial soul explains the personal identity of an embryo is problematic for many people because there is no apparent spiritual activity in the unborn. While some scholars argue that the embryo has the potential to act as an adult person and thus should be protected from harm, others contend that potentiality alone is insufficient (...) reason to ascribe special moral worth to the embryo in utero. For Thomas Aquinas, the soul is not only the life‐principle that organizes the human body, but it is also that by which the human being thinks and wills. By making suitable corrections to Aristotle's hylomorphic depiction of the soul–body relation, I suggest that a rational soul must be present from the moment of conception and that it is at the service of the person. What is of critical importance here is to accept that a human being is present from the moment of conception, something the vast majority of embryologists maintain, notwithstanding the inveiglement of those who state that the pre‐implantation blastocyst is simply a disorganized clump of cells.

Embryonic stem cell research holds great promise for biomedical research, but involves the destruction of human embryos. Katrien Devolder explores the tension between the view that embryos should never be deliberately harmed, and the view that such research must go forward. She provides an in-depth analysis of major attempts to resolve the problem.

This paper discusses two proposals to the US President’s Council on Bioethics that try to overcome the issue of killing embryos in embryonic stem cell research and argues that neither of them can hold good as a compromise solution. The author argues that the groups of people for which the compromises are intended neither need nor want the two compromises, the US government and other governments of countries with restrictive regulation on ES cell research have not provided a clear and (...) sound justification to take into account minority views on the protection of human life to such a considerable extent as to constrain the freedom of research in the area of stem cell research, and the best way to deal with these issues is to accept that many people and most governments adopt a gradualist and variable viewpoint on the human embryo which implies that embryos can be sacrificed for good reasons and to try to find other, less constraining, ways to take into account minority views on the embryo. Finally, another more efficient and time and money sparing compromise will be proposed for those who accept IVF, a majority in most societies.STEM CELL RESEARCHStem cells are widely believed to represent one of the greatest promises for medicine and biomedical research in the coming century with hopes raised for treatments for common diseases and conditions, including neurological disease or injury, diabetes, and myocardial infarct. At present there are three main lines of stem cell research, namely on stem cells originating from early in vitro embryos, left over from infertility treatment, or especially created for research through in vitro fertilisation or cell nuclear transfer cells), on cord blood derived stem cells, and on stem cells from more developed tissues or organs from foetuses ….

Medical stem cell research is currently the cause of much moral controversy. Those who would confer the same moral status to embryos as we do to humans consider that harvesting such embryonic cells entails sacrificing embryos. In this paper, the author analyses critically the arguments given for such a perspective. Finally, a theory of moral status is outlined that coherently and plausibly supports the use of embryonic stem cells in therapeutic research.

Debate on the potential and uses of human stem cells tends to be conducted by two constituencies—ethicists and scientists. On many occasions there is little communication between the two, with the result that ethical debate is not informed as well as it might be by scientific insights. The aim of this paper is to highlight those scientific insights that may be of relevance for ethical debate.Environmental factors play a significant role in identifying stem cells and their various subtypes. Research related (...) to the role of the microenvironment has led to emphasis upon “plasticity”, which denotes the ability of one type of stem cell to undergo a transition to cells from other lineages. This could increase the value given to adult stem cells, in comparison with embryonic stem cell research. Any such conclusion should be treated with caution, however, since optimism of this order is not borne out by current research.The role of the environment is also important in distinguishing between the terms totipotency and pluripotency. We argue that blastocysts and embryonic stem cells are only totipotent if they can develop within an appropriate environment. In the absence of this, they are merely pluripotent. Hence, blastocysts in the laboratory are potentially totipotent, in contrast to their counterparts within the human body which are actually totipotent. This may have implications for ethical debate, suggesting as it does that arguments based on potential for life may be of limited relevance. (shrink)

Advances in cloning technology and successful cloning experiments in animals have raised concerns about the possibility of human cloning in recent years. Despite many objections, this is not only a possibility but also a reality. Human cloning is a scientific revolution. However, it also introduces the potential for physical and psychosocial harm to human beings. From this point of view, it raises profound ethical, social and health related concerns. Human cloning would have an impact on the practice of nursing because (...) it could result in the creation of new physiological and psychosocial conditions that would require nursing care. The nursing profession must therefore evaluate the ethics of human cloning, in particular the potential role of nurses. This article reviews the ethical considerations of reproductive human cloning, discusses the main reasons for concern, and reflects a nursing perspective regarding this issue. (shrink)
