Bonaventure (Giovanni di Fidanza)

Bonaventure is the great thirteenth-century Augustinian: divine illumination, the soul as image of the Trinity, the priority of will over intellect, the impossibility of creation from eternity. He explicitly opposes the Aristotelian turn represented by Aquinas and the arts masters.

"Every creature is a shadow, an echo, a picture … a vestige, a representation, a spectacle proposed for our contemplation." (Itinerarium, II.11)

The Itinerarium is one of the masterpieces of Western mystical theology. The six stages of contemplation — through sense, imagination, reason, intellect, intelligence, and the apex of the mind — culminate in an ecstatic transitus beyond all conceptual knowledge.

"If you ask how these things come about, question grace, not doctrine; desire, not understanding; the groaning of prayer, not diligent reading." (Itinerarium, VII.6)

The structure of ascent, the doctrine of emanation and return, and the apophatic climax of the Itinerarium are deeply Neoplatonist, mediated through Pseudo-Dionysius and the Victorines.

The final chapter of the Itinerarium invokes Pseudo-Dionysius's "Mystical Theology" and the passing over into the divine darkness above all light.

Bonaventure was Minister General of the Franciscans and a cardinal. His theology is inseparable from his institutional role: defending the mendicant orders, shaping the Franciscan Rule, and combating heterodox Aristotelianism.

The Collationes in Hexaemeron (1273) are a direct institutional response to the Averroist crisis at Paris, defending the compatibility of philosophy and faith against radical Aristotelianism.

The Platonic doctrine that the sensible world is a copy or image of an intelligible archetype runs through Bonaventure's exemplarism: every creature expresses an idea in the divine mind.

"All creatures of the sensible world signify the invisible things of God." (Itinerarium, II.12, echoing Romans 1:20)
