　　Simon’sRevisedComposition:

　　Adecadeago,itwasunrealistictocloneahumanbeing.ButallhaschangedsinceasheepnamedDolly,anexactgeneticreplicaofitsmother,wasbornonJuly5,1996.Peopleallovertheworldbegantodiscussthisnewtechnologyseriouslyastheprincipleofhumancloningisthesameasthatofanimalcloning.Fiercedebatearoseovertheprosandconsoftryingtocloneahumanbeing.

　　Indeed,everyfruitofsciencehasaprospectofwideapplication.Manyproblemsregardinghumanreproductionormedicinemaybesolvedwithhumancloning.Howexcitingitwouldbewhenthelifeofapatientwithamalfunctioningorgancouldbesavedasasuitablereplacementcouldbeeasilygrowninalaboratory.Suchtransplantswouldalsoeliminatetheriskofrejectionbythebodyduetoanimmunereactionastheneworganwouldbecultivatedfromabatchofcellsfromthepatientsthemselves.Andwhatajoyfulthingitwouldbeifacopyofapersoncouldbemadetoovercomeinfertility.

　　However,alargenumberofpeopleincludingIanWilmut,whocreatedDolly,findhumancloningoffensive.Foronething,thetechnologyisfarfromperfectandtheincidencesofaliveandhealthyclonearefewandfarbetween.Shallwekillofftheoneswithadeformedbodyordefectivebrains?That,I’mafraid,wouldcausecensurefrompeoplewhoholdtotheirreligiousbeliefs.Foranother,evenifthetechnologyisperfected,whocanguaranteenoonewillmisuseitforevilpurposes?

　　Iagreethattheeviluseofhumancloningwillleadtoverydangerousconsequences.ButIdon’tagreewiththeideaofprohibitingit.Nothingcanstoptheadvancingstepsofscience.Asworldhistoryteachesus,ifonesocietyrejectsanewtechnology,anothersocietywillnot.Ithinkthereisstillalongwaytogotojudgewhethercloninghasmoreadvantagesthandisadvantagesornot.
