How is the concept of "duality" used in both cosmology (e.g., wave-particle) and philosophy of mind (mind-body), and are these uses meaningfully connected?

I'm struck by the term "duality" appearing in such different fields. In quantum physics, wave-particle duality describes how light exhibits both wave and particle properties. In philosophy, mind-body dualism posits two distinct substances. Are these just homonyms, or is there a deeper structural analogy? Does the philosophical duality try to resolve a categorical distinction (mental vs. physical), while the physical one reveals complementary descriptions of a single entity? Or could both point to limitations in our conceptual frameworks?

They are distinct but reveal a shared epistemological theme. Wave-particle duality is not an ontological claim about two substances, but an empirical and descriptive feature of quantum entities within a single theoretical framework (quantum mechanics). It's a case of complementarity: two models are needed for a complete account, but they are not simultaneously applicable. Mind-body dualism (Cartesian) is an ontological claim about two fundamentally different kinds of being. The connection is that both dualities expose limits of classical concepts (particle/wave, mental/physical) and force us to develop more sophisticated frameworks (quantum field theory, non-reductive physicalism). The philosophical lesson is similar: our everyday categories may be inadequate for describing fundamental reality, whether it's the nature of light or the nature of consciousness.
