 This is true for the medieval period, the Renaissance, and in different ways for early modern scholasticism until the eighteenth century. We should not assume, however, that the uses and understanding of probability remained unchanged throughout this long span of time. For this reason, the period from roughly 1200–1500 is singled out here for discussion. It is the period of mature medieval scholasticism and covers much of the Renaissance. In the sixteenth century, the discourse on probability underwent significant changes, on the scholastic as well as the humanist side. This early modern discourse needs to be clearly differentiated from its medieval precursor and is therefore excluded from consideration here (but see the references in Sections 4.3 and 6).
