 Suggested Reading: Balashov (2011) is an advanced overview of these issues, Hawley (2009) is much more introductory, and Gilmore (2008) is a very useful middle ground; Balashov (2008) is a more technical paper which attempts precise definitions of the rival theories of persistence against a relativistic backdrop. Broad (1927, chapter 2) is an early discussion of the links between perdurantism and STR; see also Quine (1960, p. 172); Rea (1998b, section 1.1) responds. Mellor (1981) argues that STR is compatible with endurantism, while Mellor (1980) argues that the General Theory of Relativity is also compatible with endurantism, contrary to Nerlich (1979). Balashov (1999; 2000a) argues that perdurantism can better explain relativistic phenomena. Balashov (2002) argues that STR favours perdurantism over stage theory; Balashov (2000b) raises further problems for endurantism, while Gilmore (2002) responds, followed by Balashov (2005a); Gilmore (2006) develops a relativistic version of endurance theory. Hales and Johnson (2003) weigh in against endurance theory; see also Hales and Johnson (2007), and Schmidt (2015). Further installments include Balashov (2009), Sattig (2006), Miller (2004), Harrington (2005), Gibson and Pooley (2006). See also Hudson (2005) and Balashov (2010) for book-length treatments of this and related topics. McCall and Lowe (2003) argue for an STR-friendly notion of the flow of time. Davidson (2013). Balashov (2014), and Calosi (2015) exchange arguments about four-dimensional shapes in relativistic contexts. Pashby (2013) argues that quantum objects lack temporal parts, see also Pashby (2016); Gomori and Szabo (2019) discuss the persistence of the electromagnetic field .
