Abstract: This thesis tells a story from within and between the boundaries of my professional work as a nurse and my private life as the wife of a patient with life threatening illness. The events related in the thesis are told using a technique I have called writing back to myself, where my own journals and stories of the experience of living with life threatening illness provide data for analysis. The reader is invited to participate in these representations and to consider the potential for the skilful practice of nursing which may be read in the stories, and the analysis I have developed from them. I have developed the theoretical and methodological positionings for the thesis from the work of Foucault (1975,1979,1982,1988), Deleuze (1988), Ellis (1995), Richardson (1998) and other writers who utilise genealogical or narrative approaches. The analysis of my own stories in the thesis explores the philosophical and contextual positionings of the nurse as a knowledge worker through genealogies of practice and the specific intellectual work of the nurse. Local and contextual epistemologies are considered as ways of theorising nursing practice through personal knowledge, which is surfaced through the critical analysis of contextual positionings and the process of writing as inquiry.
