Energy: a bridging concept for nursing science.

A philosophical inquiry into the concept of energy revealed two ideas of energy across multiple disciplines. Analysis of the conceptual models of Nightingale, Levine, and Rogers supported the presence of two paradigmatic views of energy in nursing science that, while divergent, share a common theme. The outcome of this inquiry leads to the tentative belief that there is unity in diversity and may perhaps lead to refinement of existing nursing theory and a more congruent framework for scientific inquiry. This article specifically addresses the nursing theoretical implications related to ideas of energy arising from the inquiry.
