  This line of argument has been criticised by Huggett on the grounds that the apparent mystery is a mere fabrication: the inaccessible non-symmetric states can be ruled out as simply not physically possible (Huggett 1995). The surplus structure, then, is a consequence of the representation chosen and has no further metaphysical significance. However, it has been insisted that a theory should also tell us why a particular state of affairs is not possible. So, consider the possible state of affairs in which a cold cup of tea spontaneously starts to boil. Statistical mechanics can explain why we never observe such a possibility, whereas the quantum-objects-as-individuals view cannot explain why we never observe non-symmetric states and hence it is deficient in this regard (Teller 1998).
