Before revision:  We investigate the issue of 'identity and indistinguishability' from this new perspective and conjecture that the way one can easily understand how two  'the same concepts' are 'absolutely identical and indistinguishable' in human language is also the way in which quantum particles are absolutely identical and indistinguishable in physical reality, providing  new evidence for our conceptuality interpretation of quantum theory.
