WebbAnother argument for monism is that it is more parsimonious, or intellectually economical. Monism suggests that there is only one ultimate reality, rather than two distinct and separate ones. This means that it requires fewer assumptions and postulates to explain the world, and it is therefore a simpler and more elegant theory.
