"Monism is the view that attributes oneness or singleness (Greek:\u03BC\u03CC\u03BD\u03BF\u03C2) to a concept (e.g. existence). Substance monism is the philosophical view that a variety of existing things can be explained in terms of a single reality or substance. Another definition states that all existing things go back to a source which is distinct from them (e.g. in Neoplatonism everything is derived from The One)."@en . . . .
