Bonaventure

The 'Seraphic Doctor' who kept Augustine and mysticism at the heart of Scholasticism.

ScholasticismHigh MedievalLatin Christian1221–1274 CE◦ Bagnoregio, near Viterbo (Italy)13th century CE

Overview

A Franciscan theologian, minister general of his order, and contemporary of Aquinas, Bonaventure represents the Augustinian-Franciscan current of Scholasticism. Against the rising tide of Aristotelianism, he held that all knowledge is illumined by God and that philosophy must lead the soul on a mystical journey to God (The Soul's Journey into God). He emphasized divine illumination, exemplarism (creatures as reflections of the divine Ideas), and love as the summit of the ascent.

What they supported — and why

Divine illumination

SupportedCertain knowledge requires God's light illuminating the mind, not the senses alone.

WhyEternal, necessary truths exceed what changeable sense-experience can supply, so a divine source of certainty is needed.

Exemplarism

SupportedAll creatures are 'vestiges' and images of God, reflecting the divine Ideas.

WhyGod created after the pattern of the eternal exemplars, so the world is a book pointing back to its Maker.

The soul's ascent to God

SupportedPhilosophy and creation are steps on a journey that culminates in mystical union through love.

WhyKnowledge is not an end but a ladder; the intellect's search completes itself in loving union with God.
