Opposites genuinely coincide while remaining opposites… opposites not only co-exist, but give rise to and fulfil one another (‘sunt complementa’), and are conjoined (like the poles of a magnet) without any intervening boundary, while nonetheless remaining distinct as opposites.
McGilchrist argues that opposites are neither identical (monism) nor merely juxtaposed (dualism) but mutually generative and inseparable, growing more differentiated the more intimately they are united.
