The Dual Aspect of Monism

I would say that monism is also very simple Right because it only has one kind of entity which grounds all reality I guess a view that I hold just to clarify is the sort of dual aspect monism where there's one irreducible substance. All mental changes has a sufficient physical cause And of course there are no mental differences without a physical difference and in mind necessarily supervenes on this physical. So both views are going to have to posit contingency and necessities in their ontology, right? The implication is if that's the case Then all reality is in consciousness or reality moving made at the qualities of experienceright?
