Ethics for embryos.

This paper responds to DW Brock's technically strong case for the use of human embryonic stem cells in medical research. His main issue in this context is the question of whether it is moral to destroy viable human embryos. He offers a number of reasons to support his view that it is moral to destroy them, but his use of conceptual arguments is not adequate to secure his position. The purpose and scope of this paper is wholly concerned with his arguments rather than with the conclusion that it is justifiable to destroy human embryos. The author proceeds through his variety of arguments and offers reasons for rejecting them. The author concludes that Brock has not shown that it is moral to destroy viable human embryos.
