the.com/dualism

Mind and body, forever at separate tables, somehow still splitting the bill.

means The view that reality (or a person) consists of two fundamentally distinct kinds of stuff — classically mind and matter — rather than one.

from From Latin 'dualis,' meaning 'containing two,' from 'duo,' two. The philosophical sense sharpened in the 1600s-1700s, with Descartes as the famous poster child for splitting thinking substance from extended, physical substance — though the word 'dualism' itself was coined slightly later by writers categorizing his and others' two-substance views, then borrowed into theology and physics for any system built on two opposed principles (good/evil, wave/particle).
