I Don't Like Critical Rationalism

I don't know sometimes what people mean when I talk about critical rationalism. It's just physics and appending Everett to it. There is optimism in David Deutsche sense but really it is just an idea that is out there in the world objective independent of anyone else nowDavid has explained these things but it doesn't make it Deutsche. He should be credited for inventing it in the first place. To continue to say well Einstein in physics it's misguided. We're not like we're best understanding of physics.
