Left incomplete at the death of St. Bonaventure (b. 1221 ) in 1274, the Collationes in Hexaemeron represent the final synthesis of Bonaventure's thought as well as his response to the controversy over the Latin Averroism at the University of Paris. J. Guy Bougerol, OFM, has written, "In perfectly clear language, manifesting thought in full possession of its means of expression, Bonaventure spoke to masters and students alike with his Intelligence and with his heart." Our reprint of the classic St. Anthony Guild edition makes this text available in English for the first time in decades.Using the six days of creation as a literary and symbolic framework, Bonaventure exposes here the conclusions of his thought in its final and highest form. His main intention is to refute the excesses of the "Artists, " that is, of those masters of the School of Arts of the University of Paris who placed exaggerated emphasis on the rationalism of Aristotle as opposed to the inspiration of the Scriptures.
