The author builds an image of a medieval person of several elements, noting at the same time additional components of his mentality. The author based his conclusion on a vast specter of compositions by outstanding theologians and philosophers of those ages. He used Lives of Saints, mystical texts, theological treatises, ‘visions’, and documents of the Inquisition. Medieval chronicles served him as material for the reconstruction of religious mentality of medieval people. At that, he made an important note: a great role in spiritual evolution of a medieval person was played by the Catholic practice of confession; it shaped a habit of reflection and self-analysis. He argued that the central and ‘formative’ idea of the Middle Ages was the longing for universal structures. He comes to conclusion about a static character of medieval worldview, in spite of diversity of outer expression. He saw the reason of such centripetal type of mentality in the existence of strong-centered Church. Thus, the religion was a specific base and explanation of the universal character of the medieval society.
