The most controversial aspect of the interpretation of Scotus’s modal theory concerns the question of whether things are possible because God knows them to be possible, or whether they are possible independently from God. I argue that Scotus thought that the possibles are possibles because of God’s knowledge of them. I adduce a number of relevant texts that previous 20th century discussions of this interpretational problem have not taken into account. In addition, I discuss the modal theory of Francis of Meyronnes (14th century) as well as the reception of Scotus’s modal theory by two Scotists of the 17th century, i.e., John Punch and Bartholomew Mastrius.
