Not your best effort. You seem to be arguing against having core beliefs. Yet having read your essays I would find it extremely hard to believe that you practice what you preach.
I'm not sure what "core beliefs" means precisely. But if it means beliefs you wouldn't discard even in the face of evidence to the contrary, it would seem good to have as few of those as possible.
I think that he isn't so much arguing against having core beliefs as he is arguing against maintaining a minimum number of social identities. Overall, I think he is taking a rationalist approach.
pg cites being a scientist as a good example of a minimalist objective. He seems to be getting at a social version of occam's razor.
