Abstract
This paper aims to examine the slippery slope argument and whether it is useful to analyze ethical problems or not, especially for matters for which it was originally used in bioethics such as euthanasia, preimplantation genetic diagnosis (PGD) and genetic engineering. This paper limits the scope to PGD. In examining the slippery slope argument with PGD, it considers the following: What is the slippery slope argument? How does it apply to the case of PGD? What is the limitation of the slippery slope argument? Finally, this work will suggest two purposes of the slippery slope argument analyzed from the case of PGD.
