This book offers a journey through the life and thought of Thomas Aquinas, one of the most influential figures in the intellectual history of the West. From his noble origins in the 13th century, his inner struggle over vocation and his years of study in Paris, to the construction of his great works and the impact of his legacy, the reader discovers not only the theologian and philosopher, but also the man: the large, silent friar, the patient professor, the believer who, in the end, called everything he had written 'straw' before the mystery of God.
