 Van Inwagen (1983) and Bennett (1984) once put forward a famous argument to the effect that the PSR entails that every truth is necessary. Since some truths are contingent, the argument is in effect an objection against the PSR, and hence potentially in favour of brute facts. The force of the argument strongly depends on which version of the PSR is taken to be involved. The argument, in one version or another, has stimulated much philosophical reflection since then (see e.g. Hudson 1997 and the reply in Feit 1998, Dasgupta 2016, and McDaniel 2019 and the reply in Werner 2020).
