Abstract
After a quarter century of research and teaching, Bernardino Bonansea offers here a clear, solid and comprehensive study of the principal elements in the teaching of the Master of the Franciscan School. He recognizes the on-going nature of the project to edit critically the works of this medieval schoolman, yet presents this study as representing the best that can be said on Scotus' positions from the most reliable of his works available. Bonansea's purpose includes both accuracy of documentation and clarity of exposition. He aims likewise to include an occasional comparison of his views with other medieval thinkers.
