Dualism

the philosophical exposition of the nature of things by the hypothesis of two di imilar primitive principles not derived from each other. Dualism in religion is chiefly confined to the adoption of a belief in two fundamental a a good and an evil one, as is done in some Oriental relirions, especially that of Zoroaster. In metaphysics, dualism is tne doctrine of those who maintain the existence of spirit and matter as distinct substances, in opposition to idealism, which maintains we have no knowledge or a urance of the existence of anything but our own ideas or sensations.
