Unity of opposites

The unity of opposites (coincidentia oppositorum or coniunctio) is the philosophical idea that opposites are interconnected by the way each is defined in relation to the other. Their interdependence unites the seemingly opposed terms.^[1]

The unity of opposites is sometimes equated with the identity of opposites, but this is mistaken as the unity formed by the opposites does not require them to be identical.^[2]
