 It should be noted that Sider and Katherine Hawley defend an alternative version of Four Dimensionalism which identifies objects with what, on the first version, would qualify as their stages (Hawley 2001, Sider 2002). In order to make this identification Sider invokes something close to Lewis’ counterpart relation. Will the table I am currently looking at persist through the next ten minutes? According to the classical four-dimensionalist, otherwise known as the perdurantist, the table will persist through that period provided it has a present and a ten minutes from now table stage that are both stages of the table without either one being identical with the table. In contrast the stage theorist identifies the table with the present stage of the table. How can that be since the present table stage only exists now, and the table is supposed to be around ten minutes from now? It can be, says the stage theorist, because, though the ten minute from now table stage is not now identical with the table, it will be identical with the table. Moreover it will be identical with the table since it stands in the appropriate counterpart relation to the present table stage.
