 Scotus’s approach to modalities brought new themes into philosophical discussion. One of these was the idea of possibility as a non-existent precondition of all being and thinking. Some of his followers and critics argued that if there were no God, there would not be any kind of modality (see Hoffmann 2002, Coombs 2004; for Bradwardine’s criticism, see Frost 2014). Scotus’s views were known in the seventeenth century through the works of Suárez and some Scotist authors (Honnefelder 1990). In his discussion of eternal truths, Descartes criticized the classical view of the ontological foundation of modality as well as the Scotist theory of modality and conceivability. (There are different interpretations of Descartes’s view of the foundations of modality and how it is related to late medieval discussions; see Alanen 1990; Normore 1991, 2006.)
