I believe that God1 is an extreme positivist, and presently I shall prove it. I also believe that we should try to emulate His system of beliefs. It follows that we should go in for extreme positivist critiques of existing theories in physics, and that this will yield a real prospect of improving them. But it also follows that we should not adopt an anthropocentric form2 of positivism. We need not, then, have positivistic doubts about the reality of the past, of physical objects, or of the microworld. I also happen to believe that the final correct theory of the universe will be almost unbelievably simple when axiomatized in an extreme positivist form.
