Introduction
It's hard to specify with exactness the beginning of an historical
period or a cultural development or even an academic discipline.
In most cases beginnings are too far in the past and become
lost. Even when relatively few years have passed from the start
of something new, initiating events may be diverse, and distinguishing
a first step from background influences is always problematic.
To talk about the beginning of bioethics, inevitably, is to
speculate.
Speculation begins with an attempt to define the term, bioethics.
In a very preliminary way, we can say that bioethics is a systematic
study of moral conduct in the life sciences and medicine. A
case can be made for the claim that bioethics is a new and indeed
a paradigmatic discipline for our era. No other discipline or
field reflects our contemporary age more faithfully. Medicine
and the life sciences are to our age what religion and salvation
were in medieval times. They are the focus of enormous societal
resources and central concerns for most modern people. Bioethics
pulls together under a single discipline the many ethical dilemmas
associated with bioscientific research and its application in
medicine. The discipline is paradegmatic because the dilemmas
force us all to grapple with the essential lfe and death problems:
who are we? why are we here? what is the meaning of family;
integrity, identity, kinship; freedom, love, community?
The issues with which bioethics is concerned are the focus of
our literature and our law. They are the topics of news stories
and editorial comment. Churches and universities struggle with
them because young and old alike are interested. People want
to understand the right thing to do for an impaired newborn
or a dying elderly parent, because everyone passes through birth
and death, and most families have some problems related to one
or the other stage. This enormously expanding field began only
recently in developed countries which had to face many new ethical
challenges generated by expanding biosciences. But the same
ethical problems now challenge people everywhere.
Developments in life sciences that gave impetus to the field
of bioethics in developed countries now are part of life in
developing nations as well. Modern hi-tech medical centers can
be found in major cities all over the world. People everywhere
face the same ethical problems associated with human experimentation.
Journalists in Europe and Latin American and Japan now give
the same prominence to ethical problems in medicine as do their
colleagues in the United States. Physicians in other countries
are equally as aware of the need to understand the ethical issues
generated by their practices and to update their professional
codes. Foreign and domestic politicians alike grapple with direct
government involvement with health care regulation, and this
means involvement with ethical choices and issues of justice.
In just a few decades, bioethics has become a major concern
worldwide and will continue to reflect the ethos of our 20th
and 21st century bioscientific civilization.
Because of its critical place in contemporary societies, the
field of bioethics has undergone a meteoric development in the
last three decades. First, bioethics centers, institutes, commissions
and boards were established in the U.S. and Canada. European
nations and the European community followed quickly with their
own initiatives. Scholars from Japan and Southeast Asian countries
spent time in Canada or the U.S. or Europe and returned to direct
the establishment of bioethics institutes in their own countries.
Bioethics conferences have already been held in Eastern Europe,
and work has started on the development of bioethics centers
there. Even recently independent countries in the former Soviet
Union and emerging nations in the former Yugoslavia are organizing
conferences on bioethical problems and planning bioethics institutes.
International bioethics exchanges have begun to take place,
and already the field is changing as a result of efforts to
develop international agreements. An origianlly dominant North
American style of bioethics is now changing under the influence
of European, Asian, and Latin American perspectives.

Contemporary Bioethics:
The Beginning Stage
In its initial stages, bioethics was concerned with ethical
issues generated by developments in medicine. In the beginning,
bioethics was almost synonomous with medical research and clinical
ethics (e.g. Nazi experiments and the Karen Ann Quinlan case).
Later the subject matter was broadened to include other aspects
of medicine and then all the biosciences. Clinical and research
ethics, however, remains a core part of this new larger field,
Difficult as it is to identify precisely the beginning of bioethics,
several events can be recognized as important contributors to
its rapid rise.
German medicine in the late 19th and early 20th centuries provided
the model for modern medicine. It was linked to laboratory science,
which meant that medical practice required proven effectiveness
of interventions based on rigorous experimentation inevitably
involving human subjects. The misuse of human subjects for medical
experimentation created the first modern ethical crises and
the first calls for a new medical ethics. The Nuremberg Code
responded with what came to be one of the foundations of this
new ethics; an informed consent requirement.
The
voluntary consent of the human subject is absolutely essential.
This means that the person involved should have legal capacity
to give consent; should be so situated as to be able to exercise
free power of choice, without the intervention of any element
of force, fraud, deceit, duress, overreaching, or other ulterior
form of constraint or coercion; and should have sufficient knowledge
and comprehension of the elements of the subject matter involved
as to enable him to make an understanding and enlightened decision.
This latter element requires that before the acceptance of an
affirmative decision by the experimental subject there should
be made known to him the nature, duration, and purpose of the
experiment; the method and means by which it is to be conducted;
all inconveniences and hazards reasonably to be expected; and
the effects upon his health or person which may possibly come
from his participation in the experiment.(1)
The
violation of traditional medical ethical standards by misusing
patients created widespread moral outrage. The persons used
as subjects trusted that doctors were doing something beneficial
for them. Vulnerable, weak, and needy human beings suffered
dehumanization and even death, and this called for new ethical
standards. Quickly the new ethical standards were extended from
medical experimentation to medical treatment because vulnerable
patients required protection there as well. Benefit balancing
and disclosure of dangers and voluntary consent became as much
a part of treatment as of experimentation.
News of grossly unethical behavior by some Nazi physicians during
World War II was followed in the U.S. by a series of revelations
of similar ethical failures (Willow Brook School, Jewish Hospital
in New York, and the Tuskegee Syphilis Study). In 1966 Henry
K. Beecher, a Harvard physician, published an article in the
New England Journal of Medicine in which he exposed
common patterns of unethical conduct in medical research.(2)
Beecher's article on the misuse of human subjects by U.S. physicians
was widely publicized and contributed substantially to public
interest in revising the ethics of medicine. Ethical failures
associated with research launched a new field of study which
later came to be called bioethics. Concern about ethics in experimentation
is as strong today as it was at the beginning with modern medicine.
This is as true elsewhere in the world as it is with the U.S.
The imperative to make scientific progress in medicine is present
anywhere contemporary medicine is practiced. Because the authority
of physicians tends to be stronger in foreign countries than
it is in the U.S., conditions exist there as well for similar
ethical failures. Only a well-developed and widespread bioethics
can keep ethical tragedies associated with research from occurring.
No society can afford to leave the balancing of individual patient
rights with scientific progress, solely in the hands of medical
scientists. Standards for the conduct of human experimentation
need to be developed everywhere modern medicine is practiced.
This is true in the great medical centers certainly, but even
small community hospitals in developing countries have become
places where testings of medicine and other research occurs.
Research forced changes in medical ethics and forced national
and international health care organizations to be concerned
with educating and then monitoring medical professionals.

Bioethics and Government Involvement
After World War II, many of the developed nations put great
emphasis and large amounts of money into the medical field.
Consequently, greater attention had to be given to the ethical
issues which inevitably accompanied medical advances. In the
United States, the U.S. Public Health Service (an agency of
what later would be called Health and Human Services (HHS))
was made responsible for protecting the rights and welfare of
human research subjects. In the 1960s, it promulgated ethical
standards for the conduct of research. In the 1970s, a National
Commission for the Proteciton of Human Subjects of Biomedical
and Behavioral Research was formed. Members of the commission
worked for four years and made 125 recommendations for improving
protection of the rights and welfare of research subjects. This
commission also published the Belmont Report. In it
were identified the basic ethical principles (respect, beneficence,
justice) which guide contact with patients and subjects. Subsequently,
the federal government under the auspices of the same Public
Health Service continued to update regulations and to require
assurances of ethical compliance from any group carrying out
research on human beings. The U.S. government, through its financial
support of medical projects, became a source of bioethics policy
and rules. It established commissions which articulated ethical
justifications for a new ethical approach in the conduct of
medical practice. The U.S. government played a major role in
the development of modern bioethics.
After the National Commission's work, the U.S. government continued
its involvement, now in the form of a President's Commission
for the Study of Ethical Problems in Biomedical Research. This
commission was formed in the 1980s and mandated to provide reports
to the President, the Congress, and relevant departments of
government in order to guide politicians in developing legislation.
In addition, its work provided guidance to health professionals,
health educators, and the general public. The President's Commission
published eleven volumes, nine reports, the proceedings of a
workshop on whistle blowing in research, and a guidebook for
local committees that review research with human beings. The
work of this government commission has had an enormous influence
on U.S. bioethics. A list of the commission's works provides
some indication of just how bioethics expanded in the first
few decades: Compensating for Research Injuries; Deciding
to Forgo Life Sustaining Treatment; Defining Death; Implementing
Human Research Regulations; Making Health Care Decisions; Protecting
Human Subjects; Screening and Counseling for Genetic Conditions;
Securing Access to Health Care; Splicing Life; Whistle Blowing
in Biomedical Research.

Bioethics and Medical Technology
Flowing from government investment in medical science were all
sorts of new medical technologies and therapeutic interventions.
The linkage of medicine with science which had begun in the
late 19th century now began to pay off handsomely in the form
of new medicines, dialysis machines, organ transplant techniques,
mechanical organ support systems, medically delivered alimentation
techniques, ICUs, lifesaving surgeries etc. Each new development
created new ethical problems. In the 1960s an ethics committee
in the state of Washington tried to make ethically defensible
decisions about who would receive dialysis when the scarce technology
could not be provided to all. Modern bioethics is not just concerned
with medical experimentation on human subjects and with humane
medical treatment. From the very beginning it has been concerned
with the participation of patients and communities in decisions
about socio-economic issues of access and distribution of scarce
resources.
Historically the medical profession always accepted moral responsibility
for the exercise of physician power over patients. Traditionally
medical ethics expressed this responsibility in professional
medical codes and ethical treatises published by medical associations.
All socially authorized professional power requires public accountability,
and this is especially true of medical professional power. The
right to practice medicine is associated with moral restrictions
on that practice imposed either from within the profession or
from outside by the government. As medical interventions became
mroe powerful, ethical problems associated with medical practice
proliferated. The range of things physicians could do for patients
expanded along with the intrusiveness of their interventions.
Micro problems arose with each intervention. Macro problems
concerned with the relationship of technology and human life
also had to be addressed. In both developed and developing nations,
physicians became pressed to update their ethical codes. They
were not leaders in developing the new discipline of bioethics,
but gradually they began contributing to the field.
Scientific and technological medicine moved medical treatment
procedures into the public forum. Medical treatment moved out
of the privacy of an office or a home and began to take place
principally in public hospital settings where ethical responses
had to be publicly defensible. The technologies of the next
millennium will make earlier therapeutic interventions look
primitive and uncomplicated, but we can see in early breakthroughs
the driving force behind the new focus on ethics and the emergence
of this new discipline called bioethics.
Before the 1950s, "doctors know best" captured the attitude
most people had toward medicine and summarized a traditional
paternalistic medical ethics. After the Nuremberg trials and
the increased influence of experimentation on practice, this
older paternalistic ethics gradually gave way to different standards
of right and wrong. Other attitudes, different norms, and different
principles coalesced to create the beginnings of modern bioethics.

Role of Nongovernmental Institutes
The disicpline of bioethics developed from more than government
initiatives. Nongovernmental institutes and centers also sprang
up to respond to the pressing new medical problems.
As early as the 1950s, the Institute of Religion at Texas Medical
Center in Houston, started working on ethical issues in medicine.
A Society for Health and Human Values was formed by religious
thinkers interested in promoting the humanities in medical education.
In the 1960s the first Department of Medical Humanities was
formed at Pennsylvanian State University Medical Center in Hershey,
PA, with a faculty weighted toward medical ethics. The 1970s
witnessed the appearance of the Hastings Center in Hastings,
NY (late 1969) and the Kennedy Institute of Ethics at Georgetown
University (1971). All these initiatives attempted to bring
depth and rigor to the new discipline referred to now as bioethics.
The Kennedy Institute followed a university model. It developed
a National Reference Center for Bioethics Literature which,
in effect, became the best library resource in the world for
an expanding new literature. Its scholars came from many different
disciplines, worked somewhat independently of one another, and
served as faculty for a doctoral program in Bioethics at the
university. One of the first scholars, Warren Reich, a Catholic
theologian, put together the Encyclopedia of Bioethics,
which became a major literary resource for the discipline. A
Protestant scholar, Leroy Walters, started an annual Bibliography
of Bioethics and developed "Bioethics Line," an on-line
computer database. As new areas of the expanding field of bioethics
emerged, scholars from the new areas who were interested in
ethics came to the Kennedy Institute to study, to write and
to teach.
The Hastings Center was started by Daniel Callahan, a Catholic
layman with a background in philosophy and theology. At the
Hastings Center scholars were brought together to work both
independently and in groups in order to develop sound ethical
policies for specific problems. The Hastings Center continues
to publish policy recommendations and topical reports and to
influence government responses both directly and indirectly.
The Hasting Center Report, founded in 1971, carried
articles on ethical issues in medicine, the life sciences, and
the professions. It was the first and has remained the most
important journal in the field.
Since
these nongovernmental bioethics institutes were founded, literally
hundreds of centers, programs, journals, and newsletters concerned
with bioethics have sprung up. Every year books and articles
on bioethical subjects number into the tens of thousands. From
a small and recent beginning, bioethics has become a major field
of study. The American Hospital Association in 1987 published
a list of 77 bioethics organizations. In 1994 the National Reference
Center for Bioethics Literature at Georgetown University published
an International Directory of Bioethics Organizations
and the number of entries more than doubled in just five years.
Now they have doubled again and number over 300.
In the early 1970s, supported by grants from the National Endowment
for the Humanities, the Institute on Human Values in Medicine
and the Society for Health and Human Values inaugurated a project
to develop bioethics in medical education. A prominent physician/humanist,
Dr. Edmund Pelligrino, and some staff members visited over 80
medical schools to introduce faculty and students to the new
discipline and to set up an educational program for future generations
of doctors. They wanted to make sure that bioethics moved from
literary texts and reports and commissions to changes in the
clinical practice of ordinary physicians.
The Pellegrino effort was directed toward a promotion of the
relationship between medicine and the humanities. When the effort
began, very few medical school offered courses on human values
in medicine. When it ended, after ten years, almost every medical
school and many schools of nursing were offering courses in
bioethics and other medical humanities. These visits to medical
schools and personal contacts with medical school faculty made
the big difference. After Pelligrino, bioethics became a practice
as well as an academic discipline.(3)
Government commissions, academic centers and nongovernmental
institutes combined to contribute to the development of bioethics
in the U.S. Interest on the part of professionals stimulated
them to go to a growing number of bioethics education institutes.
Academically based bioethics centers trained professionals for
teaching posts in the new field. Hospitals sometimes hired their
own bioethicist for education and consultation, thereby creating
job opportunities for trained bioethicists. Bioethics committees
were organized in health care settings, and committee members
needed education in a field which now had an extensive literature.
Attitudes of resistance and skepticism towards a humanities
component in scientific medicine gradually gave way to acceptance
on the part of medical faculties, students and practicing professionals.
The thousands of articles and books annually on bioethics (many
of which now written by physicians) testify to what this field
has become over the last few decades.

Bioethics and the Law
Bioethics is not just a new field of study. It is a topic the
general public reads about in newspapers and sees on television.
Famous cases in bioethics like the Karen Ann Quinlan case are
as well known as movie stars and prominent politicians. Widespread
public interest in complex and conflict ridden problems meant
that politicans, legislators, and lawyers were also interested.
The propensity in the U.S. is to look for legal solutions to
life's problems and this led to an immediate involvement of
bioethics with the law.
When issues raised by experimentation and treatment could not
be resolved at the patient-physician-family level, they were
taken to the courts. The first court cases involved tragic situations
with dying patients. Families and hospital staffs disagreed
about whether to withdraw life-sustaining technologies, and
courts were asked to make life and death decisions. The disputes
attracted the media and created front page stories. People wanted
to hear about the tragic case which touched concerns and worries
in every family. Court decisions in the highly publicized cases
contained arguments that themselves stimulated further arguments.
Later court decisions either approved or overturned earlier
ones, and a whole corpus of legal bioethics literature came
to be.
The combination of media attention and public interest made
bioethics important to politicans who saw the need for creating
statutes to defend patient and family rights in health care
settings. Now every state and province in North America has
laws covering bioethical concerns. New laws and new cases continue
the active involvement of politicans and judges. Other nations
are facing the same pressures. Lawmakers and judges outside
the United States, will look to the U.S. experience for help
in developing sound legislation.
In Europe and North American, the law adopted many of its positions
from ethics. For centuries Catholic moral theology held that
patients have a right to refuse any treatment, even life-sustaining
treatment, if it is burdensome, risky, costly, or in the language
of theological ethics "extraordinary." Statutory law and court
cases upheld this moral teaching. And the influence went both
ways. Secular and religious bioethicists adopted standards for
decision-making which were developed in law: e.g., subjective
standard (what the patient actually choses), substitute
judgement (what the patient would have chosen), then best
interest (what is considered medically best for the patient).

The Expansion of Bioethics
At the beginning stage, bioethics addressed the ethical problems
associated with research and medical practice but quickly expanded
to social issues related to healthcare access, animal welfare,
and environmental concerns. Every bioscientific advance or change
in the healthcare system contributed to the expansion of bioethics.
The first ethical problems with which bioethics began have not
disappeared. Experimentation, the humane use of technology,
questions about death and dying, abortion and contraception,
all are still very much a part of bioethics in the 1990s. Allocation
of medical resources too was a problem at the start of modern
bioethics. The first ethics commissions in the 1960s tried to
bring defensible ethical standards to allocation decisions about
scarce medical technologies. Later the allocation issues expanded
as states and governments struggled to decide how equitably
and justly to distribute ever more scarce medical resources.
Some idea of the breadth and complexity of the field today can
be gained by looking at the classification scheme of the National
Reference Center for Bioethics Literature, or the multiple volumes
of the Bibliography of Bioethics (edited by Leroy Walters
and Joy Kahn).
Bioethics has undergone an incredible development corresponding
to the expansion of biosciences. The original bioethical issues
expanded to value-related problems in all health professions:
nursing, allied health, mental health, hospice, home health
care, etc. A broad range of social issues are now included under
the term "bioethics": public health, occupational health, international
health, popualtion control, women's issues and environmental
concerns. The clinical issues have expanded to include issues
related to reproductive technologies, transplants, genetics,
cloning and molecular biology. The connection between the concerns
of contemporary bioethics and contemporary culture is obvious.
Bioethics is considered a paradigmatic discipline in the U.S.
because it reflects who we are and what worries us as Americans
facing the new millenium.
The expansion of bioethics to address the ethical dilemmas so
characteristic of modern culture provided crucial assistance
to societal leaders, both political and professional. But society
and societal leaders were not the only ones to benefit. Ethics
itself benefitted from bioethics. In 1973 Stephen Toulmin argued
that medical ethics had saved ethics from decline and disinterest.(4)
The problems with which medical ethics grappled not only created
a new interest in ethics, but saved academic ethics from an
irrelevance created by an overly abstract, rationalistc, linguistic
approach. Philosophers, theologians, lawyers, doctors and social
scientists suddenly found the ethical aspects of medicine and
biosciences to be areas of fascination and started studying
them. Their challenge was to make ethical concepts and arguments
applicable to clinical contexts and relevant to persons working
in clinical medicine.

The Future of Bioethics
Will the astounding expansion and central importance of bioethics
continue into the next century? A quick and clear response to
this question arises from considering two recent bioethics issues:
the genome project and AIDS.
Once the human genome is mapped, and information locked in human
genes is opened, the ethical problems generated by this new
information will explode. This has already started to happen
with every discovery of genetic links to disease. The information
developed by genetic research has ominous as well as hopeful
potential. Data banks of individual DNAs could be established.
Government agencies, police, employers, and insurance companies
could literally categorize human lives and destroy human initiatives
if they were to gain access to the data. Only with well thought
out ethical standards and judiciously developed ethical policies
can the worst results imaginable be avoided. The very dignity
and freedom of human life swings in the balance between ethical
and unethical handling of this one bioscientific project.
The genome project is the life science project of the 1990s
and can easily be compared with the physics project to unlock
the power of the atom in the 1940s. The potential for good is
great, but unless the associated ethical issues are openly discussed
and thought through in advance, human life as we know it today
in a civilized, free and democratic society may be undermined.
The sheer numbers of ethical complexities are hard to imagine,
but the ominous consequences of not attending to the bioethical
dimensions of this project are even more ominous. With good
reason a percentage of the money allocated for the genome project
is committed to bioethics. Ethical questions generated by genetic
developments are already present in clinical settings but in
nowhere near the intensity which will develop once the new knowledge
turns into new therapies.
AIDS is another biomedical challenge shot through with ethical
dilemmas. LIke so many other diseases with which physicians
have battled over the years, waging an effective and aggressive
campaign against AIDS requires attention both to its biological
and bioethical dimensions. Sound strategy has from the start
considered scientific and ethical dimensions of the disease.
Committements to find vaccines and therapies have been joined
with campaigns to protect the human rights and dignity of people
with HIV and AIDS. Efforts to stop transmission of the disease
are combined with efforts to stop discrimination against disease
bearers in employment, travel, housing, access to heatlh care,
and in hospital-based medical care provided by doctors and nurses.
AIDS, like the genome project, shows the inevitability of bioethics
in contemporary life as well as the ever expanding complexity
of this field. On the pragmatic, concrete level, there are problems
of confidentiality; allocation of resources; use of human subjects
for research; health policy development for schools, work place,
prisons, and society at large; education and public campaigns;
privacy; screening; informed consent; and on and on. No single
aspect of the AIDs epidemic is devoid of its bioethical dimension.
Bioethics will continue to expand and to be considered important
as far as we can see because biological sciences will remain
critical and the two are inseparable. Ethical policies will
be required in every institution. Codes and laws, both national
and international, political and professional, will have to
be developed, then continually improved and updated. No end
is in sight for new roles for clinical professionals who are
conversant with modern medical ethics. The discipline which
emerged in the last half of the 20th century in the U.S. and
Europe is now a world wide enterprise. It is hard to imagine
that it will not still be with us long into the coming millenium.
