For us, subjectively speaking, the self, understood as the experiencer (and the doer) is the basis of "all this". Without experiencers the world would not appear at all. We can take a more detached scientific perspective and say the world is more basic since the self is born into a pre-existing world. These are two imaginable perspectives; how do we decide between them? Do we need to claim that one or the other is the "true" perspective? Or should we not deploy whichever perspective is the more useful for the task at hand? — Janus
