Issues related to the provision of medical care, research, the relationship between human activities and the environment, and public health ethics are all subfields of bioethics. Bioethics encompasses a broader range of topics, including the philosophy of science and concerns related to biotechnology, than medical ethics, typically understood only in applied professional ethics. The lines between the two are often blurred, and any separation is more a matter of personal preference than widespread agreement among experts. Providing health care to individuals with varying beliefs and practices in a diverse and multicultural society requires us to weigh the pros and cons of various ethical scenarios constantly. Amid so much variety, where do we turn to moral compass points when we are uncertain or at odds over what is right? Such norms would have to find widespread support among believers, atheists, and people of various ethnicities and socioeconomic backgrounds. Although there are no absolutes in clinical medicine, the involved can find strong action guides in a handful of ethical principles that seem applicable across various situations.
