Care, I suspect, is initiated with an appeal. Something appeals to me which becomes a matter of concern. In accordance with this concern, I develop a volition: I want that which promotes the thriving—even to the smallest extent—of that which has appealed to us, regardless of how I may establish what that entails. Eventually I take practical action: I act according to my volition. Immediately after this has taken effect, as the case may be, I release the source of the appeal from my care.The phenomenology of care seems to us to be of eminent importance for health care ethics. To denote professional caring, the term nursing is used. The professional care-giver purposefully exposes him/herself to an appeal, making him/herself receptive to such an appeal and reliably allowing the appeal to become a concern. A fundamental principle of nursing ethics thus appears to us to be: to make known one's receptiveness to an appeal—in a particular situation at a particular time—and to process this appeal reliably such that it becomes a concern. This encompasses the professionalism of care at its initiation.I believe that a precise phenomenology of care will provide a definition of the professional care that is nursing and an ethics of nursing for the care-giving professions.
