"5. "Not accountable to others"? Surely you are not saying that it does not matter what one believes?"

When a mind has discovered an answer to the fundamental metaphysical question, "why", that mind does not need to account to others for how that answer was derived. That is quite a different matter from "belief", which so often appears to involve insincerity, delusion and a distortion of objective reality that results in conflict and suffering.

This is such a clear distinction. It is possible to just "know" the answer. That knowledge is independent of others' beliefs or convictions or opposition and needs no explanation or justification.
