St. Bonaventure of Bagnoregio's The Soul's Journey into God is a masterpiece of thirteenth-century Scholasticism. Unfortunately no comprehensive analysis of Bonaventure's seminal treatise exists that is accessible to contemporary audiences. Reinvigorating the medieval tradition of critical commentary for the twenty-first century, Peter Dillard's A Way into Scholasticism: A Companion to St. Bonaventure's The Soul's Journey into God introduces readers to basic Scholastic concepts and arguments by expounding and evaluating Bonaventure's speculative system. Dillard also highlights the relevance of Bonaventure's thought for contemporary philosophical theology.
