Human genetic enhancement: is it really a matter of perfection? A dialog with Hanson, Keenan, and Shuman.

The author reviews the arguments made by Mark Hanson, James Keenan, S.J., and Joel Shuman in this issue. In the first section, she argues that they offer a significant contribution toward an understanding of the inner logic of a new trend in contemporary medicine, genetic engineering. However, she criticizes the authors for relying excessively on procedural guidelines and for failing to bring the practical realities of medicine and technology to bear on theory. She argues that more concrete guidelines, which are ultimately grounded in a Christian conception of the person and on the commandment to love, are necessary. Writing from the Roman Catholic perspective, the author argues that the distinction between genetic enhancement and gene therapy is essential, despite the criticisms which have been offered of this distinction. Understanding this distinction will be critical for identifying as licit only those forms of genetic manipulation which respect the dignity of the human person.
