This definitive text demonstrates the connection between theoretical nursing and nursing practice, and shows how research is related to both. From Nightingale to the present, the author traces the work of major theorists through a description and analysis of the theory along with a critique and test of the theory. Coverage also the processes and strategies used to develop theory; the most accepted criteria used to analyze and critique theory; and discussion on the use of theory to enhance the nursing profession. Four new chapters provide students with the most current information on the development of concepts and theory and A Nursing Perspective, Patterns of The Syntax of the Discipline, Strategies for Concept Development, and On Practical Wisdom . Bibliographies and reference lists have been expanded to include writings through early 1996, and incorporate contemporary philosophical discussions and interpretive approaches to knowledge development.
