Human Cloning and Bioethics: Arguments For and Against
This paper examines the bioethical debate surrounding human cloning and genetic engineering, with particular focus on the arguments for and against permitting cloning research to continue. Drawing on sources from the Human Cloning Foundation, bioethics scholars, and scientific commentators, the paper considers cloning's potential to address infertility, challenges common fears about loss of individual identity, and compares cloning to naturally occurring identical twins. It also addresses religious and philosophical objections, situating human cloning within a broader history of once-controversial medical technologies that eventually gained public acceptance.

What makes this paper effective
- The paper directly engages opposing viewpoints — particularly fears about identity and the "playing God" argument — and responds to each with reasoned counterarguments, giving the essay a genuine argumentative structure.
- The use of the identical twins analogy is an accessible and rhetorically effective way to demonstrate that genetic similarity does not override individual identity.
- Contextualizing cloning alongside previously controversial technologies (birth control pills, in vitro fertilization, heart transplants) grounds the argument in historical precedent and makes the position feel measured rather than dismissive.
Key academic technique demonstrated
The paper models refutation-based argumentation: it states a common objection (e.g., clones would lack individuality or a soul), then systematically dismantles it using evidence and analogy. This technique strengthens a persuasive essay by showing awareness of the opposition and responding to it directly rather than ignoring it.
Structure breakdown
The essay opens by defining bioethics and introducing cloning as a contested topic. It then pivots to the central thesis — that cloning should be allowed to develop despite public resistance — and supports this through three main areas: medical benefit (infertility), philosophical rebuttal (identity), and ethical/religious rebuttal. The conclusion ties back to the broader theme of society's historical pattern of fearing new medical technologies before eventually accepting them.
Introduction to Bioethics and Cloning
Bioethics — the study of value judgments pertaining to human conduct in the area of biology, including those related to the practice of medicine — has been an important aspect of all areas of the scientific field (Bernstein, Maurice, M.D.). It is one of the factors that determines whether certain scientific research can proceed, and if so, under which rules and regulations it must operate. One of the most recent and controversial issues facing society today is the idea of cloning. Dolly the sheep was the first mammal clone and was born in February 1997 in Edinburgh, Scotland. After considerable news coverage, genetic engineering of DNA was thrust into the spotlight. The world has engaged in heated discussions over the issues surrounding cloning ever since.
In the past, people have opposed experimental procedures because of the possibility of deadly outcomes. Because not much is yet known about genetic engineering, this discovery could improve our lives and should be allowed to progress despite the risks it poses and the public outcry against it.
Public Fear and Mistrust of Genetic Engineering
It is true that we are just beginning to discover the dangers and benefits of genetic engineering, and a great deal of important information still remains unknown. But instead of recognizing the potential benefits of this discovery, the American public has developed a "growing mistrust of science" (Whitman 1) and a fear of the unknown. Many people automatically reject this breakthrough rather than engaging with its possibilities.
Cloning as a Solution to Infertility
Human cloning has the power to address infertility, a painful reality that many couples throughout the world face. "The current options for infertile couples are inefficient, painful, expensive, and heartbreaking" (Human Cloning Foundation 1). Many couples run out of time and money without successfully having children. According to the Human Cloning Foundation, fewer than 10% of current infertility treatments are successful. Human cloning could make it possible for many more infertile couples to have children than ever before by boosting success rates through nuclear transfer of sperm from the father into the mother's egg, thus creating a unique child.
Identity, Individuality, and the Clone
One concern raised by those opposed to cloning is that a clone would have no soul, no mind, no feelings or emotions of its own, no say in how its life unfolds with its destiny predetermined, and that cloned individuals would not be truly unique. Critics also worry that a clone would not be treated as a full person, but rather as a worthless second copy or a replacement for someone lost. Although genes play an important part in shaping a person, it is the interaction among a person's genetic inheritance, their environment, memories, different life experiences, and the process of learning that produces the uniqueness of each individual (Mario, 1997).
Moreover, when we think of making a copy of a person through cloning, we tend to assume that the clone will possess the same knowledge and memories as the original. This kind of information transfer between individuals is far beyond the reach of mere physical duplication. It would therefore be unrealistic to expect clones to replace the original individuals they were copied from.
Nature clones people all the time. Approximately one in every 1,000 births produces identical twins. Yet despite however many individual characteristics twins may share, they remain different people. They have their own identities, their own thoughts, and their own rights. They enter different occupations, develop different diseases, and have different experiences with marriage, community life, and countless other aspects of living. Twins develop different personalities — and so would cloned individuals. Even if several genetically identical individuals were produced, each would be different and perhaps even more distinct than twins, since each cloned child would be raised in a different setting. Cloning, therefore, does not rob individuals of their personality or uniqueness.
Conclusion: Weighing the Benefits Against the Risks
At one time, birth control pills, in vitro fertilization, and heart transplants were all criticized on similar grounds. Genetic engineering and human cloning could someday serve as tools to cure many problems that afflict humanity. The possibilities could be endless if we do not allow ourselves to be paralyzed by fear of the unknown.
