Why should there not be ‘stuff’, or ‘real things’ instead of weird quantum mechanics at some microscopic scale? In other words, how can we accept that direct realism is wrong without getting too ‘difficult’.
Accepting that the world is in some sense in our minds is not aimed at encouraging ‘spirituality’ or whatever the euphemism for religious craziness is nowadays. I have none of that! Not even any switching on of consciousness once we add a little quantum magic to a zombie’s brain. There is indeed a deep connection* between consciousness and quantum physics, but for this article here, let’s forget about that connection.
