 Suggested reading: This is a large field, but Rea (1995) provides a helpful overview, and the papers collected in Rea (ed.) (1997) are a useful next step. Sider (2001, chapter 5) and Hawley (2001, chapters 5 and 6) also survey this area, both from a temporal-parts perspective. Korman (2015: chapter 11) and Sattig (2015: chapters 3 and 5) provide more up-to-date entry points to the debate. The standard account is advocated or discussed sympathetically by Doepke (1982), Baker (1997), Fine (2000; 2003), Johnston (1992), Robinson (1985), Levey (1997), Lowe (1983; 1997; 2003), Moyer (2006), Oderberg (1996), Rea (1997), Simons (1985; 1986; 1987; 1997), Yablo (1987), Thomson (1983; 1998), Paul (2006) and Wasserman (2002); critics include Olson (1997), Heller (2000), Hughes (1997a; 1997b), Lewis (1971), Noonan (1993) and Burke (1992). Gilmore (2007) argues that endurance theorists can handle coincidence by paying attention to the appropriate notion of spatiotemporal location; Eagle (2010a) criticises this argument, and Gilmore (2010) responds, followed by Eagle (2010b). McGrath (2007a) argues that temporal parts views suffer the same difficulties as the standard account; Hawley (2008) discusses this further, whilst Hawley (2005) explores related issues; see also Donnelly (2016). Moyer (2009) argues that coincidence is neutral between endurance and perdurance; in response, Eddon (2010) defends perdurance; Rychter (2011) also defends perdurance here. Sattig (2008) argues that perdurantists cannot combine coincidence with informative identity criteria. Temporary identity is advocated by Baxter (1989) and Gallois (1990; 1998). The claim that objects can be very easily destroyed is advocated by Burke (1994a; 1994b; 1997a; 1997b) and Rea (2000), and critically discussed by Carter (1997), Denkel (1995), Lowe (1995b), Noonan (1999b), Olson (1997a), Zimmerman (1997) and Zammiello (2001). Restrictive ontologies are discussed by Chisholm (1973), Elder (1999), Merricks (2000; 2001), Olson (1996; 1997b), van Inwagen (1981; 1990b), and Zimmerman (1997; 1995); Sidelle (1998) explores a number of interesting options, as does Needham (2010). Walters (2019) draws connections with debates in mereology. It’s hard to avoid Wiggins (1980; 2001). The classic discussion of permanent coincidence is Gibbard (1975). Temporal-parts accounts of permanent coincidence include Noonan (1988; 1993; 1999a). Counterpart theory is advocated by Lewis (1986, chapter 4). Magidor (2016) argues that the arguments discussed in this section cannot settle the endurance-perdurance debate. A more formal approach to problems concerning change of parts can be found in the separate entry on  mereology,  especially in section 3.2; further discussion can also be found in the separate entries on  material constitution,  on  relative identity  and on  ordinary objects.
