Ron takes his discussion of the new physics beyond matter to mind and language. Is matter the ultimate reality? Last time we discovered there is more mystery to matter than most people realise. But this time we move into the even more important question of whether matter is the only building block of the universe - or whether the mind, and language, are just as primary as matter. Of course it suits materialists like Dawkins to say that matter is the only real stuff. But Ron challenges that view here. He introduces us to the 400 year old debate over this topic, and shows how inadequate a 'matter is all that matters' view really is.
