What is Bioethics?
Study of ethical issues arising from biological and medical sciences
Varieties of Bioethics
Medical ethicsPhysician-centered
Health care ethicsIncludes nurses & other healthcare professionals
Clinical ethicsHospital care decisions with aid of committees and consultants
Bioethics in generalIncludes issues in genetics, reproductive technologies, experimentation, and distribution of life-saving resources
Normative Ethics
Developing principles that tell us which actions are right, and what we are morally required to do.
Normative Theories
Deontological theoriesAssociated with German philosopher Immanuel Kant.
Consequentialist theoriesMost well-known theory is utilitarianism.Utilitarians seek to maximize general human happiness or well-being.Famous utilitarian philosophers include John Stuart Mill and Jeremy Bentham.
Deontological Theories
A type of action is right or wrong no matter what its consequences are.Moral agents have duties which oblige them to do certain types of action.Duties can be specified in the form of rules that must be universally applicable.Persons and their autonomy should be respected at all times.
Consequentialist Theories
What makes an action right or wrong are its consequences.The consequences of an action can always be measured by a common standard: what it contributes to the good of all who are affected by the actionThe right action is one that has the maximum beneficial results.The same unit of benefit to any person should be given equal weight.
What is Applied Ethics?
Use of general moral principles to test the morality of particular actions.
Problem for Applied Ethics
Presence of competing moral principlesDoes this make applied ethics subjective?
Room for reasoning, argument and justificationEthics is not a matter of taste.
Ethical dilemmas are real dilemmasThere are no easy answers.
Important to learn why people disagree
EthicsEthics is about dilemmadilemma and thereasonsreasons that we give for our choice of action “should do, ought to do”
Medicine is about that is the bestFor the patient
Doing the right thing for the patienthas not only a factual but also amoral dimension
