With a "big tent" understanding of bioethics, this dictionary provides definitions of 755 important terms drawn from a wide variety of contexts: medicine, nursing, behavioral health, forensic science, research ethics, public safety, social work, and epidemiology, on the one hand; bioethics, ethics, law, history, philosophy, and theology, on the other. Bioethical approaches (such as Principlism) and ethical categories (Fallibilism) are given their due, as are the major theoretical orientations (Feminist Bioethics). Terms from outside the USA, especially the UK, are in evidence. Many Greek and a few Latin equivalents are provided; for example, "cloning (4;5;a4;_7; = twig or branch)." Cross references abound. That's Part 1. Part 2 offers single-paragraph introductions, 95 in all, to Historical Figures from a number of fields: medicine and nursing, dentistry and pharmacy, certainly; but there are also philosophers, scientists, environmentalists, public health pioneers, noteworthy psychologists and psychiatrists--along with many others. The religions are not neglected: important Christian thinkers are represented along with nine famous clinicians from the Islamic Golden Age. This resource offers the definitions of important terms and the identifications of historical figures that everyone interested in bioethics should have access to.
