Quantum Mechanics - A New Possibility to Anti Realism

Anti realism is saying that there is no such thing as reality. And what quantty mechanics is? Is it a set of symbols or bookkeeping devices? That's exactly what mathematics is. Now chancarroll goes on to say, fortunately, we have not yet exhausted all our possibilities. So now he's going to present a new possibility to anti realism. This is a different interpretation of quantum mechanics. He says the simplest possibility is that the quantum wav function isn't a bookkeeping device at all,. nor is it one of many kinds of quantum variables. The way function simply represents reality directly.
