Members of the nursing community have been engaged in numerous debates, some of which are related to the roles of holism and particularism in the care of clients and in the development of nursing knowledge. Others center on most and least congruent methodologies for nursing research, These healthy debates have played a significant role in invigorating the discipline of nursing.
