Part of what you said, was “demonstrate its coherence”. And that’s a part that I didn’t like. I don’t think we ever demonstrate the coherence or incoherence of anything. “Coherence” is not defined well enough to be demonstrable. We make our own personal assessments about coherence, and we may present arguments intended to persuade others to make the same assessment. But those arguments always fall short of anything that I would consider to be a demonstration.
