 A different sort of response to definitional worries is to recast the debate between presentists and non-presentists as a debate concerning two distinct, opposing theses: transientism and permanentism. Whereas presentism and eternalism are views about what exists, transientism and permanentism are views about whether things begin or cease to exist. Transientism is the view that: sometimes, something begins to exist and, sometimes, something ceases to exist; permanentism is the view that: always, everything always exists (Deasy 2015, 2017, 2019a; Cameron 2016; cf. Sullivan 2012).
