Is this drawing too fine a line? And is it really important to press the issue of nursing knowledge versus knowledge of and for nurses? The answers to these questions are probably found in one's concept of nursing as a field of knowledge (discipline) and a human service (profession). It seems that nursing and nurses have suffered significantly over the years with this dilemma. Is it possible to have a sense of self as nurse without a concomitant sense of nursing as a discipline which is more than tacit and to which one is committed? Students of nursing and practitioners alike have abundant opportunities to acquire a sense of self as nurse. Yet why is it that many programs of nursing education (at all levels) do not convey a sense of nursing as a discipline? The answer may lie in those conducting the programs, who have experienced training for practice and education in disciplines other than nursing and without explicit education in the discipline of nursing. From the perspective of Nursing as Caring, with its grounding in person as caring and nursing as discipline, the distinctions implied in this question of "does it really matter" are of central importance. Nurses in practice, education, and administration continue to address nursing primarily in terms of "what nurses do," (e.g., nursing "interventions") and most nursing research seems to derive from that perspective as well. Without a clearly articulated understanding of the focus of the discipline, it has been extremely difficult to organize and structure nursing knowledge in ways that facilitate the development of the discipline. In this book, we have offered a theory, Nursing as Caring, as one expression of that focus, languaged in terms that communicate the essence of nursing. Nursing knowledge is knowledge of nurturing persons living caring and growing in caring within shared lived experiences in which the caring between nurse and nursed enhances personhood. Furthering nursing knowledge requires methods that can illuminate the central phenomenon of the discipline. The development of such a methodology is, as we see it, the next major effort to be undertaken in the development of the theory. In this regard, we envision a fully adequate methodology that would include a phenomenological aspect which goes beyond description to a hermeneutical process, within an action research orientation. That is, what seems to be needed is a methodology that would permit the study of nursing meaning as it is being co-created in the lived experience of the nursing situation. Supplemental methods could continue to include traditional phenomenological and hermeneutic work with texts describing particular nursing situations. Nurses who are interested in developing knowledge of techniques or modes of expressing caring would continue to use traditional methods of formal and human science for these kinds of nursing-related questions.
