碩士 === 國立中央大學 === 哲學研究所碩士在職專班 === 95 === The development of bio technology, make hum an beings solve to th e mystery of the life and change human beings concept of the life , medical treatment, value, etc. Development of gene therapy make a lot o f future patients that have illness might become current patients in med ical research and change us to the definition of the disease. Gene therapy h as two kinds: the first therapy is the somatic cell gene therapy, changed of the gene will not be transmitted to the sublings. The second therapy is germ-line cell gene therapy, changed the hereditary quality to change in the sperm, ovum or zygote. Leroy Walters& Julie Gage Palmer＇ s view, that somatic cell gene therapy is expanding of traditional treatme nt. Because germ-line cell gene therapy can change the defect gene and stop th e hereditary disease to subli ngs. The future patient is radical cured before the disease has not taken place . Yet their sublings cann''t happen defective genes in future. Singer think, parents already do their best to influence the environmental factors that undoubtedly also play a part in shaping these characteristics. They can now influence genetic factors as well as environmental ones , in one of three ways . By using in vitro fertilization, they can have the embryo screened before implantation ; they can use prenatal diagnosis and selective abortion ; and they can obtain eggs , sperm or embryos from people they regard as genetically superior . According to reasons, we discuss prenatal genetic screening and germ-line ce ll gene therapy to cause morals dispute with loo king for the acc eptable argumen t . Singer is an utilitarian. We will realize his theory and his view to the han dicapped person. Chapter 3 introduced the defini tion of the disease that the gen e disease can be suitable, and then treat. The kind of gene therapy, gene enhanc ement and eugenics are our focal points. S inger argues to prenatal geneti c screening and gene selection to presume germ-line cell gene therapy. Finally, we discuss the dispute of germ-line cell gene t herapy and Singer＇ s response Key words: genetic malady, somat ic cell gene therapy, germ-line cell gene therapy , preference utilitarianism, principle of equal conside ration of interest,genetic enhancement, e ugenics, prenatal ge netic screening, abor tion, Pre-implantation Genetic Diagnosis, sanctity of life, slippery slope argument, the life commercialized.
