Early thirteenth-century accounts of human action and the freedom it involves focus on the notion of free decision (liberum arbitrium).  This term, a legacy of Roman law and patristic thinkers, has no present-day counterpart, and even to thinkers in Grosseteste’s day its sense was unclear and stood in need of determination.  But if the notion of free decision itself is now of merely antiquarian interest, accounts of free decision are nonetheless important for the insight they provide into their authors’ understanding of human action and freedom, issues of perennial philosophical concern. (On Grosseteste’s theory of free decision see Lewis 2013, 2017, and Pickavé 2017.)
