RT Journal Article SR Electronic T1 When four principles are too many: a commentary JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 197 OP 198 DO 10.1136/medethics-2011-100385 VO 38 IS 4 A1 Raanan Gillon YR 2012 UL http://jme.bmj.com/content/38/4/197.abstract AB This commentary briefly argues that the four prima facie principles of beneficence, non-maleficence, respect for autonomy and justice enable a clinician (and anybody else) to make ethical sense of the author's proposed reliance on professional guidance and rules, on law, on professional integrity and on best interests, and to subject them all to ethical analysis and criticism based on widely acceptable basic prima facie moral obligations; and also to confront new situations in the light of those acceptable principles.
