Answering the question of who is experiencing the illusion [of self] or interpreting the story is much more problematic. This is partly a conceptual problem and partly a problem of dualism. It is almost impossible to discuss the self without a referent in the same way that is difficult to think about a play without any players. Second, as the philosopher Gilbert Ryle pointed out, in searching for the self, one cannot simultaneously be the hunter and the hunted, and I think that is a dualistic problem if we think we can objectively examine our own minds independently, because our mind and self are both generated by the brain. So while the self illusion suggests an illogical tautology, I think this is only a superficial problem.
