 It is fairly widely held that more than one object can occupy the same spatio-temporal location. Such objects are said to be spatio-temporally coincident. The classic example is a statue, Goliath, and the lump of clay that constitutes it, Lumpl (see Gibbard 1975). On one version of the story, Lumpl sits around on a shelf for a few days before the sculptor shapes it into Goliath on a Thursday morning. It looks like Lumpl existed on the previous Wednesday and that Goliath did not, and consequently looks like Leibniz’s Law entails that they are distinct objects. On another version of the story, Lumpl and Goliath are created and destroyed at precisely the same moment. Here the two do not have different temporal properties, but they do have different modal ones—Lumpl would still exist if we squashed it into a ball, but Goliath would not. Again, Leibniz’s Law apparently entails that they are distinct. (See Rea 1997a for many interesting papers on this issue.)
