Nursing claims a significant history of engaging philosophical inquiry. To better understand the rationale for this engagement, and what nursing understands itself to achieve through philosophical inquiry, we conducted an interpretive synthesis of the recent nursing literature to identify what nurses are doing when they say they are doing philosophy. The overarching finding was that while vanishingly few articles articulated any definition of philosophy, the synthesis showed how nursing considers philosophical engagement a generative mode for asking and answering questions in/for (...) nursing. Whatever aspects of nursing were focused on in these articles, and they were myriad, philosophy was invoked as an appropriate modality to work through that aspect rigorously, critically, and with an expectation that something “knowledgeable” would result from the effort. Based on the synthesis, we conclude that nursing philosophy could be considered a specific modality of nursing practice by which nursing is both done and delineated, a discursive practice in which we continually assess and explore and adapt and advance our understanding of the discipline in service to advancing our unique efficacy. This definition of “nursing philosophy” provides an opening for further inquiry helping to illuminate its functionalities and potentialities for outputs that can facilitate rigorous practice, education, and scholarship.
