Bonaventure’s entire theological project is deeply prayerful, and many of his most famous works are bookended by prayer. This is nowhere more evident than the Itinerarium, which begins by advising souls seeking peace to cry out in prayer, and ends with David’s words from Psalm 73—invoking mystical “passing over” into Christ through death. To read Bonaventure rightly is to stand in humility before God, the immeasurable Creator Whom no one can see and still live.

John Dupré was, at the time of this book’s writing, a philosopher of science at Stanford University (now at the University of Exeter) and was part of the so-called Stanford School of the philosophy of science.
