I read the first chapter of Metaphysics: A Very Short Introduction and my conclusion is nothing exists outside of the mind! A cup, a table, a circle they are all constructs of the mind. As humans, we developed a language to convey what’s in our minds. This language allows us to describe a set of properties as objects to which we give distinct names for using in our invented language. A cup only has meaning to you if you understand the language. Let’s say language is a universal concept or force that allows minds to communicate with other minds. Even our bodies don’t exist outside of the mind. We construct bodies for the purposes of distinguishing different minds. We could say that there is only ONE mind that has separated into many minds. The illusion is that we are separate when in fact we are one. This whole elaborate show we have here is just one bored mind entertaining itself by endlessly creating more “minds.”
