It seems that your view is then almost identical to mine, except you seem to be hesitant about setting any truth-value to your beliefs outside your own perspective. Understandable carefulness.. but I've got nothing better to do, so I'll challenge it anyway

Just like with medical sciences, we don't have to competely understand what "perfect health" is in order to make objective decisions regarding to healthcare. We

wrong and no respectable professional doctor has to take that person seriously.
