 Another motivation can be found in Burke (1997), inspired by Laycock. Burke was concerned to resolve the coincidence puzzle between not only a thing and its constituting piece of matter, but between these things and the matter per se. (Since some copper can persist past the shattering of a piece of copper which constitutes a statue, then presumably the copper is distinct from either). Burke’s account, all the details of which do not concern us here (see the entry on  material constitution  and the supplement  Sums and Ordinary Objects  for details) requires that the statue and piece of copper be identical. If this is so, and the statue comes into existence, and is identical with its constituting piece, then a new piece must come into existence and the old one cease to be. One of the options Burke canvasses to explain why it is that we (mistakenly) assume the piece continues in existence is because the copper persists through the change:
