This paper examines the work of Benner (From Novice to Expert: Excellence and Power in Clinical Nursing Practice. Addison-Wesley, Menlo Park, CA, 1984) on expertise in clinical nursing. The philosophical foundations of her work are explained as well as the work located within the wider context of the use of Heideggerian philosophy. Various criticisms of her study are developed in relationship to her methodology and her interpretation of nursing. It is argued that she represents a retreat into tradition and authority in nursing.
