Note 8. To the Subsection “Difference and Homogeneity between Sungsang and Hyungsang”
Unification Thought ontology is “Unification Theory” or “Theory of Oneness,” which is a kind of monism, a monism with dual characteristics. The Theory of Oneness is different in its character from the monisms of materialism and spiritualism (idealism). Materialism is a monism in the sense that it considers matter to be prior to spirit, and spiritualism is a monism in the sense that it considers spirit to be prior to matter. Hence, both materialism and spiritualism are relative monisms. In contrast, the Theory of Oneness claims that the origin of spirit and matter is one; therefore, it is an absolute monism.
