In the philosophy of mind, mind–body dualism denotes either that mental phenomena are non-physical, Hart, W. D. 1996. "Dualism." pp. 265–267 in ''A Companion to the Philosophy of Mind'', edited by S. Guttenplan. Oxford: Blackwell. or t ...

is ill-defined,
According to Harald Atmanspacher, "dual-aspect approaches consider the mental and physical domains of reality as aspects, or manifestations, of an underlying undivided reality in which the mental and the physical do not exist as separate domains. In such a framework, the distinction between mind and matter results from an epistemic split that separates the aspects of the underlying reality. Consequently, the status of the psychophysically neutral domain is considered as

Pauli-Jung conjecture
Pauli and Jung's approach to dual-aspect monism has a very specific further feature, namely that different aspects may show a
complementarity in a quantum physical sense. That is, the Pauli-Jung conjecture implies that with regard to mental and physical states there may be incompatible descriptions of different parts that emerge from the whole.
[Quote: "In the ''Pauli-Jung Conjecture'' these manifest aspects can even be incompatible or complementary, a feature that is not part of any other dual-aspect approach today. The possibility of incompatible descriptions of parts emerging from wholes clearly drives from Pauli's knowledge of this key concept of quantum theory, and it suggests that structural elements of quantum theory may elucidate our understanding of the psychophysical problem."
