Dialectical Monism

Dialectical monism, also known as dualistic monism, is an ontological position that holds that reality is ultimately a unified whole, distinguishing itself from monism by asserting that this whole necessarily expresses itself in dualistic terms. For the dialectical monist, the essential unity is that of complementary polarities, which, while opposed in the realm of experience and perception, are co-substantial in a transcendent sense.
