Truth and Reality: The Wisdom of St Bonaventure is a thorough study and exposition of the last work for which St Bonaventure was responsible before his death in 1274. Collations on the Hexaëmeron, also called The Illuminations of the Church, is comprised of lectures that he gave in Paris in 1273 to Franciscan and other students and masters in the university there. They were recorded by two independent witnesses, and one version, the definitive one, was prepared for publication and approved by Bonaventure. One of the most interesting, original and important texts of medieval theology, it has been well translated and edited in a new edition. In this study, Dales examines the precise context for the approach that Bonaventure took, placing this work as the culmination of his spiritual theology and providing the reader with a lucid epitome of the contents of the text, while drawing out their significance for theology and prayer in the life of the Church today.
