Abstract
Nursing theory should reflect the pluralism inherent in nursing practice. Nurses routinely enact different kinds of knowledge in combination to achieve good nursing care. Nursing theoretical and philosophical literature includes many attempts to engage with epistemological pluralism. In this paper, concepts from the work of Michel Serres are introduced as a contribution to the resources available to think pluralistically about nursing. Serres' work is valuable because he is a pluralist thinker, who uses different conceptual tools to explore the complexity of human life, including topology, isomorphism, and the excluded third. Serres' terms are discussed with examples of application to nursing. An extendeddd example of addictions nursing is used to pull together different concepts applied to a complex and multilayered area of practice.
