Contemporary philosophers tend to assume that fundamental things exist at the micro-level. Coleman (2006) calls this “smallism”: the view that facts about big things are grounded in facts about little things, e.g., the table exists and is the way it is because the particles making it up are related in certain extremely complicated ways. However, the work of Jonathan Schaffer (2010) has brought to prominence an alternative picture of reality. According to the view Schaffer calls “priority monism”, facts about little things are grounded in facts about big things. The table’s atoms exist and are the way they are because the table exists and is the way it is; and all things ultimately exist and are the way they are because of certain facts about the universe as a whole. For the priority monist there is one and only one fundamental thing: the universe.
