CHAPTER ONE
1.1. GENERAL INTRODUCTION
With the Becconian dictum ‘knowledge is power”, scientist
have gone the extra mile on how to improve the environmental condition and then
revamp the quality of human life. Now, we witness a great and extraordinary
progress in Bio-technological sciences and medicine. This great advancement in
medicine and biotechnological sciences has given human beings new pattern of
life. However, these efforts of the scientists and biotechnologists have paved
ways for extension of scientific researches on the human person. Thus, the
great question is: Are these scientific and biotechnological discoveries a
blessing or a curse to humanity?
Now, we can talk of manipulations on
human genetic constitution. Modern biotechnologists and scientists have changed
the status quo in biology and medicine. Presently in Biotechnological sciences, we
hear of microsurgery on a two weeks embryo. A stem cell from a human embryo can
now be made to turn into a heart, kidney or any major organ cells and replace
any damaged cell of the human body, thereby, providing opportunity for
manufacturing human spare parts. Scientists claim to produce human embryo
through various means like natural reproduction, asexual reproduction, and
parthenogenesis. Through these means, they have thrown the entire humanity and
the scientific community into confusion as when human life begins.
However, among all these, the most
prominent discoveries include the prodigious changes in genetic engineering,
like human foetal experimentations, eugenics, sterilization, in vitro
fertilization, abortion, surrogate motherhood, and cloning. In addition, human
modifications, such as plastic surgery, sex change, and the preservation and
commercialization of human organs and embryos are all strange scientific
possibilities. All these are topics in bioethical debates and controversies in
biotechnological sciences and medicine. Such issues like the foregoing raised
ethical and moral questions. When does human life begin? What is the status of
the human embryo? Is human embryo a human person? Does human embryo have legal
and moral right? All these are basic ethical question raised by the activities
of these scientists and biotechnologists on the human person. Sequel to this,
many groups developed positions to defend the human life and thereby restore
the human dignity.
In this work, I specifically choose to explore
the issue of human cloning. In fact, the
central question is: “Should humans be cloned?” Moreover, scientists and
biotechnologist have deviced artificial methods of creating human beings. This
touches the beginnings of human life, together with the quality of life and end
of the human life. The point is that human cloning involves intentional
creation and destruction of human being in the name of saving the life of
others. Is killing a person’s life to save another’s morally good? That is a
basic ethical issue. According to Pope John Paul 11 “what is technically
possible is not always morally admissible” Hence, in his address to the
International Congress on the Transplants on 2000-AUS-29, he comments,
“Medical…methods that fail to respect the dignity and value of the person must
always be avoided.”
As part of the introduction, this chapter
includes the setting of the whole work in its methodological framework. Let us
consider these frameworks.
1.2. THE STATEMENT OF PROBLEM
Since the birth of the sheep named
Dolly in 1997, the possibility of human cloning has left very little to be
doubted. Thus, many debates have been going on about the issue. Should humans
be cloned? If humans are cloned, what would be their social status? Who is
responsible for cloned humans? Do clones have rights and legal protection?
Should the deformed cloned individual be accepted?
In actual sense, human cloning techniques
involve intentional creation and destruction of human embryos either for transplantation
or experiments. The American Association for the Advancement of sciences
summarized the problem in these words:
…. not only do most attempts
to clone mammals fail, about 30 percent of clones born alive are affected with
large offspring syndrome and other debilitating conditions. Several cloned
animals have died prematurely from infections and other complications… the
attempt to clone humans at this time is considered potentially dangerous and
ethically irresponsible.
However, there is diversity of
opinions on human cloning. Its morality has been argued. Although, each
argument has some interest to protect, the fundamental question is: Should
humans be cloned? This is a problem that needed an urgent attention in
biotechnological sciences. Here, we need to redefine the status of the human
embryo. Human embryo is not just an object for experimentation but rather a
unique and distinctive being, and should be accorded a profound respect and
dignity. His uniqueness and distinctiveness differentiate him from every other
creature. This is the dilemma of the modern science and technology especially
genetic engineering.
1.3. THE PURPOSE OF STUDY
The real question is what has this work to contribute to
the global debates on the issue of human cloning? That is towards resolving the problem of
human cloning. Naturally, it is not ethical or moral to kill. It is against the
moral law to destroy another person’s life. But embryos are deprived the right
to live by denying them “personhood” by some biologists. This is the basis for
their exposure as objects of research and experimentation.
The purpose of this work as a matter of fact,
is to look at the scientific practices or researches on human life and their
ethical implications. This consideration will necessarily lead to a
redefinition of the status of human embryo in the face of biotechnological
sciences. We hope to find out the proper place for the fertilization of the
human embryo, whether in the womb or in the Petri dish outside the womb.
1.4. THE SCOPE OF STUDY
As we observed above, the discoveries
in the modern biotechnologies are too broad. An attempt was made to restrict
the topic to human cloning and its ethical implications. Recognizing the fact
that humans are not the objects for scientific and biotechnological
research(s).
Hence, this work shall not only
explore the arguments on human cloning but shall also look at its ethical
implications. Since no researcher can boost of thorough exhaustive of its
topic, this work does not also claim any exhaustive study of human cloning. It
is just a contribution to the contemporary problems in bioethics. Every effort
is made to explicitly state the ethical implications of human cloning.
1.5. METHODOLOGY
The methods employed in this
investigation are exposition and critical analysis. The expository method is
used to lay bare the dangers of human cloning, recognize the dangers in the
exercise and also draw some implications. On the other hand, the analytic
method is employed to explain certain terms in the study. Some of the human
cloning arguments are analytically discussed. The relevant information and
statistical data for effective discussion of our topic are collected from the
library and the Internet.
1.6. THE DIVISION OF WORK
The work is divided into chapters,
and subsections for easy explication. In all, there are five chapters. Chapter
one deals with the general introduction; setting the work forth in a
methodological framework. In chapter two, the explication of the terms was
made. I tried to explain the meaning and the purpose of ethics as the guide to
scientific and biotechnological practices in any experimentation that involve
human being. Still, the biological and philosophical conceptions of person-hood
and human-hood are explored so as to furnish us with the true status of the
human embryo.
Chapter three is the backbone of the
work. It deals with the meaning and historical background of cloning. Also, the
reasons, methods and the dangers of human cloning are equally highlighted in
this chapter. The focus of chapter four is on the uniqueness of the human
person, which trying to x-ray the legal and moral status of unborn member of
human family. This aim is realizable through an examination of the diverse
debates on human cloning. The whole endeavour is brought to a close in chapter
five through a critical evaluation.
