Norman Kretzmann on Alexander Broadie's Introduction to Medieval Logic (Journal of Symbolic Logic 55 [1990]: 1320-22):
The sort of thing Broadie does in these chapters could have been very valuable, I think, as an exercise for advanced students who had learned some medieval and some contemporary logic and were set the task of assimilating some bits of the former to corresponding bits of the latter; but it cannot count as "a sketch of logic during the fourteenth century", or as an introduction to medieval logic. A better title for the book might be Fantasia and Variations on Familiar Themes Drawn From Medieval and Post-Medieval Scholastic Logic.
