 Immanent realists say that a universal is in some sense ‘wholly present’ in each thing that instantiates it (Armstrong 1978: 79; Bigelow 1988; O’Leary-Hawthorne 1995; Smith 1997; O’Leary-Hawthorne and Cover 1998; Paul 2002, 2006, 2012; Newman 2002; Hawley and Bird 2011; Lafrance 2015; Peacock 2016). This makes it natural to hold that disjoint universals frequently interpenetrate.
