Since our genes dictate to a large extent what we look like, how we behave and what we can and cannot do, having identical genes, as identical twins do, ensures something more than mere similarity. Novelists and filmmakers have not been slow to exploit the imagery afforded by cloning. Limitless numbers of identical beings manufactured from existing or previous generations has obvious dramatic potential, although seldom of a reassuring nature. Clones traverse the cinema screen as crowds of dehumanized humans destined for monotonous drudgery, as invincible armies of lookalikes from outer space, as replicas of living megalomaniacs and, in the ultimate fantasy, as the resurrected dead - troupes of little Hitlers and herds of rampaging dinosaurs. Of course, this is science fiction. Nonetheless there is just a whiff of plausibility, a whisker of scientific credibility; enough to plant an indelible vision of what might be, or even what could be.
             Some opponents of cloning believe that such individuals would be wronged in morally significant ways. Many of these wrongs involve the denial of what Joel Feinberg Ph.D. has called "the right to an open future." For example, a child might be constantly compared to the adult from whom he was cloned, and thereby burdened with oppressive expectations. Even worse, the parents might actually limit the child's opportunities for growth and development: a child cloned from a basketball player, for instance, might be denied any educational opportunities that were not in line with a career in basketball. Finally, regardless of his parents' conduct or attitudes, a child might be burdened by the thought that he is a copy and not an "original." The child's sense of self-worth or individuality or dignity, so some have argued, would thus be difficult to sustain.
             The ethical issues of greatest importance in the cloning debate, however, do not involve possible failures of cloning technology, but rather the co
