The ethics of organ donation.

As organ transplantation is physically possible within a tension between common biological properties and individual immunities, so it is ethically possible within a tension between individual personality in full integrity and the human community of which each member, social by nature, is an organic part. Ethical donation is by consent, explicit or presumed, spontaneously offered or procured by request. Altruism or commercial dealing is now a live issue in organ procurement, whether cadaveric or by live donation, related or unrelated. Attention is given to children in transplantation, and to new developments with fetal organs, neural tissue, bone marrow and xenografts. Given all that medical science and skill can now offer, patients are still free to decline.

Pre-embryo research.

The subject is first identified in terms of the new understanding of a pre-embryonic phase preceding the traditional embryonic and fetal periods of formation and development. Sample fields and purposes of pre-embryonic research are instanced, some with direct therapeutic intent, others with foreseeable but not immediate clinical application. The ethics are discussed, first to answer the question, should it be done at all, and then, how it may be properly done.

Gene therapy, human nature and the churches.

Moral analysis must begin with respect for the empirical features, the "facts of the case". Major advances in genetic knowledge and technology -- as in other sciences -- inevitably change mental attitudes. But they could not change human nature, a product of the distinctively human cerebral cortex. Human capacities like compassion and justice are our own and for us to guard. To ask (as some do) about a "right" to inherit a non-manipulated genome is to ask an unanswerable question: the language of rights is inappropriate in this context. Parents have a duty to safeguard and to serve the interests of their potential child. The medical duty is to help in that task in ways which they have limited freedom to choose. The role of churches is to be faithful to their deposit of faith and their theological principles, including that of freedom of conscience. Churches are too easily led in practice to over-rule conscience on grounds of authority, ecclesiastical or biblical, not sustained by convincing reason. This is most evident in some declarations concerning human reproduction. Better were it for them to help their faithful in moral reasoning, the ethics of choice; to keep consciences tender.

Screening for fetal and genetic abnormality: social and ethical issues.

In answer to questions raised by practitioners, an ethics of genetic screening is located in a tension between liberty and responsibility in three respects: (1) to nature and biological processes; (2) to the disposal of human life; and (3) to the relation of persons to society. Under (1), the obligation to pursue research, fundamental as well as applied, is affirmed, offering the benefit of economy with fetal life, but requiring discrimination between the beneficial, the trivial, and the bizarre. Under (2) the abortion question, when relevant to diagnosed abnormality, is discussed, not in the language of conflicting rights, but of the relation of duties to interests. Under (3) the familial and social dimensions of screening raise questions of the disclosure of information and the keeping or extending of confidences. Last comes the value placed on truth in two related areas of developing practice. In infertility treatment, the donors of gametes are required to remain anonymous. Gene tracing through families requires for its effectiveness some correspondence between assumed identity and genetic identity. This conflict of social policies should be resolved.

In-vitro fertilization: the ethics.

This paper is addressed to practitioners. It seeks to acquaint them with 'ethical' arguments against their work which, because they are simple and plausible, persuade many people. These arguments are briefly rehearsed and as briefly examined. A more positive ethics of in-vitro fertilization is presented which seeks to respect (a) what is known in the relevant science and done in developing practice; (b) the inseparability of research from clinical application; (c) a moral tradition of long-standing which relates the protection of fetal life pari passu with its own morphological growth towards maturity; (d) the moral sense of properly informed persons whose judgements we trust in other areas of life. Practitioners themselves are to be defended as the proper moral agents (that is, to be entrusted with decisions) provided that they are careful (a) to keep public confidence by means of a corporate self-discipline; (b) to keep faith with patients and research subjects; (c) to maintain mutual trust between research scientists and clinical practitioners; (d) to safeguard the liberty of disciplined enquiry, of purposeful curiosity, as being inherent in the notion of a science, necessary to therapeutic advance, and proper to the nature of man. The author writes from within the theological tradition of the Church of England.
