noun
monism
Philosophical term for the view that reality consists of one fundamental substance or principle.
一元論は、精神と物質を一つの原理で説明しようとする。
Monism attempts to explain mind and matter through a single principle.
From 一 (one) + 元 (origin, principle) + 論 (theory, argument). A modern philosophical term likely coined in the Meiji period as a translation of Western 'monism'.
