The vague, obscure mysticism which played a part in Luther’s spiritual development at that time, as well as his wrong, one-sided interpretation of the Epistle to the Romans, had, as already stated, led him into a heterodox by-way. A cursory glance at the influence of Scholasticism and Mysticism on his mental progress, may perhaps be here in place. 4. Preliminary Remarks on Young Luther’s Relations to Scholasticism and Mysticism In the years of Luther’s development the two great intellectual forces of the Middle Ages, Scholasticism and Mysticism, no longer exercised quite so powerful an influence as of yore, when they ruled over the world of intellect. Their influence on Luther’s views and his career was diverse. Scholasticism in its then state of decay, with its endless subtilties and disputatiousness, which, moreover, he knew only under the form of Occam’s nominalism, repelled him, to his own great loss. As a result he never acquired those elements of knowledge of true and lasting value to be found in the better schools, of which the traditions embodied the work of centuries of intellectual effort on the part of some of the world’s greatest minds. Mysticism, on the other hand, attracted him on account of his natural disposition, so full of feeling and imagination. He had been initiated into it at the monastery by the works of Bernard of Clairvaux, Bonaventure and Gerson, and, later, by the sermons of Tauler and the so-called German Theology. This study had been recommended him by Staupitz and also by his brother monks, especially by Johann Lang. It was, however, the more obscure and ambiguous writings and extracts from mystic works which appealed to him most, owing to his being able to read into them his own ideas.
