What is the difference between metaphysical dualism and metaphysical monism?

Dualism is the theory that there are two opposite principles in everything, for example good and evil or the state of having two parts while Monism is the belief that there is only one god.

Is this a rethorical question? Probably not.

The Merriam Webster dictionary defines "metaphysical" as that which is of or related to a reality which is beyond what is readily perceptible by the ordinary senses. For a full description please see...
