 Suppose that, instead of first forming or digging up the lump of clay then later moulding it into a statue, you make the two halves of the statue separately, then create both statue and large lump in one fell swoop, by sticking the halves together. Later, you petulantly smash the thing into pieces, destroying statue and lump simultaneously. Here, it seems that the lump of clay and the statue coincide at every moment at which either exists, yet they seem to be distinct objects because they differ in how they could have been: for example, the statue could have been made of a different lump of clay, but the lump could not. Talk of temporal parts doesn’t help here: lump and statue share all their temporal parts, and differ only in their modal features (in how they could have been different).
