 Consider the combinatorialist David Armstrong. He eventually acquiesced to the empty world by relaxing his account of truthmakers. A truthmaker is a piece of reality that makes a statement true. Armstrong believes that every contingent truth is made true by a truthmaker and has wielded the principle forcefully against analytical behaviorists, phenomenalists, nominalists, and presentists. Since there can be no truthmaker for an empty world, Armstrong appears to have a second objection to the empty world (supplementing the objection based on his combinatorial conception of a possible world). Yet Armstrong (2004, 91) instead claims that the empty world could borrow truthmakers from the actual world. His idea is that the truthmakers for possibilities are actual objects and that these actual objects could serve as the truthmakers for the empty world. David Efird and Tom Stoneham (2009) object that cross-world truthmakers would be equally handy to the analytical behaviorists, phenomenalists and their ilk. Whether or not Armstrong has contradicted himself, he has illustrated the persuasiveness of the subtraction argument.
