There is an enormous scholarly literature on Augustine's account of free will, and it is remarkable for the range of views it contains. Historians of philosophy read Augustine on free will so variously that it is sometimes difficult to believe they are reading the same texts. John Rist says: 'There is still no consensus of opinion on Augustine's view of each man's responsibility for his moral behaviour . . . There are those who attribute to Augustine the full-blown Calvinist position that each man has no say in his ultimate destiny . . . Other interpreters reject this view in varying degrees. They will not hold that for Augustine man's will is enslaved, or they would dispute about the sense in which it is enslaved and the sense in which it is free.'
