Idealism and materialism as two kinds of monism
The dualists said that there are two kinds of things or properties in the universe, and with the failure of dualism, it is natural to suppose that maybe there is only one kind of thing in the universe. Not surprisingly, this view is called “monism” and it comes in two flavors, mentalist monism and materialist monism. These are called “idealism” and “materialism,” respectively.
