In Chapter 1, we noted that each profession arose from some everyday service given by one person or another. Nursing has long been associated with the idea of mothering, when mothering is understood as nurturing the personhood of another. The ideal mother (and father) recognizes the child as caring person, perfect in the moment and unfolding possibilities for becoming. The parent acknowledges and affirms the child as caring person and provides the caring environment that nurtures the child in living and growing in caring. The origins of nursing may well be found in the intimacy of parental caring. The roles of both parent and nurse permit and at times even expect that one be involved in the intimacy of the daily life of another. The parent is present in all situations to care for the child. Ideally, parents know the child as eminently worthwhile and caring, despite all the limitations and human frailties. As we recognized in Chapter 1, professions arise from the special needs of everyday situations, and nursing has perhaps emerged in relation to a type of caring that is synonymous with parenthood and friendship. The professional nurse, schooled in the discipline of nursing, brings expert knowledge of human caring to the nursing situation. In the early years of nursing model development, nursing scholars endeavored to articulate their discipline using the perspective of another discipline, for example, medicine, sociology, or psychology. One example of this endeavor is the Roy Adaptation Model, in which scientific assumptions reflect von Bertalanffy's general systems theory and Helson's adaptation level theory (Roy and Andrews, 1991, p. 5). Parson's theory of Social System Analysis is reflected in Johnson's Behavioral System Model for Nursing and Orem's Self-Care Deficit Theory of Nursing (Meleis, 1985). A second trend involved declaring that the uniqueness of nursing was in the way in which it integrated and applied concepts from other disciplines. The emphasis in the 1960s on nursing model development came as an effort to articulate and structure the substance of nursing knowledge. This work was needed to enhance nursing education, previously based on rules of practice, and to provide a foundation for an emerging interest in nursing research. Nursing scholars engaged in model development as an expression of their commitment to the advancement of nursing as a discipline and profession, and we applaud their contributions. It is our view, however, that these early models, grounded in other disciplines, do not directly address the essence of nursing. The development of Nursing as Caring has benefited from these earlier efforts as well as from the work of more recent scholarship that posits caring as the central construct and essence (Leininger, 1988), and the moral ideal of Nursing (Watson, 1985).
