RT Journal Article SR Electronic T1 To clone or not to clone--a Jewish perspective. JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 105 OP 107 DO 10.1136/jme.25.2.105 VO 25 IS 2 A1 J H Lipschutz YR 1999 UL http://jme.bmj.com/content/25/2/105.abstract AB Many new reproductive methods such as artificial insemination, in vitro fertilisation, freezing of human embryos, and surrogate motherhood were at first widely condemned but are now seen in Western society as not just ethically and morally acceptable, but beneficial in that they allow otherwise infertile couples to have children. The idea of human cloning was also quickly condemned but debate is now emerging. This article examines cloning from a Jewish perspective and finds evidence to support the view that there is nothing inherently wrong with the idea of human cloning. A hypothesis is also advanced suggesting that even if a body was cloned, the brain, which is the essence of humanity, would remain unique. This author suggests that the debate should be changed from "Is cloning wrong?" to "When is cloning wrong?".
