"These ideas go as far back as Ancient Greece, which basically gave birth to two lines of thinking, two ideologies, materialism and idealism. And the idealist thinkers like Plato regarded reality as a projection of our minds, as something that is not real. And the only thing that is real is our consciousness and our minds and everything else around us is just constructs of our proception and projections. And that was a philosophy that was opposed to materialism, which regards the world as in a materialistic way, made up of atoms and matter and our minds are a product of these chemical reactions and the matter is coming together and forming our minds and consciousness. And everything in the world exists regardless of our consciousness or our minds and the universe is there and it's a materialistic view of the world. So these are two competing ideologies, and this is actually how we see the world today in a materialistic way."
