His friends generally stood in a certain awe of his greatness, though, in their case, we can account otherwise for their admiration. Later writers too, even amongst the Catholics, felt in the imposing language of his writings the working of a powerful mind, much as they regretted his abuse of his gifts. “His mind was both sharp and active,” such was the opinion of Sforza Pallavicini, the Jesuit author of a famous history of the Council of Trent; “he was made for learned studies and pursued them without fatigue to either mind or body. His learning seemed his greatest possession, and this he was wont to display in his discourse. In him felicity of expression was united with a stormy energy. Thereby he won the applause of those who trust more to appearance than to reality. His talents filled him with a self-reliance which the respect shown him by the masses only intensified.”[875] “Luther’s mind was a fertile one,” he writes elsewhere, “but its fruits were more often sour than ripe, more often abortions of a giant than viable offspring.”[876] His alert and too-prolific fancy even endangered his other gifts by putting in the shade his real intellectual endowments. “His imagination,” Albert Weiss truly says, “was, next to his will, the most strongly developed of his inner faculties, and as powerful as it was clear. Herein chiefly lies the secret of his power of language.”[877] To his temperamental and intellectual qualities, which undoubtedly stamped his works with the impress of a “giant,” we must add his obstinate strength of will and his extraordinary tenacity of purpose. Were it possible to separate his will from his aims and means, and to appreciate it apart, then one could scarcely rate it high enough. Thousands, even of the bravest, would have quailed before the difficulties he had to face both without and within his camp. The secret of his success lay simply in his ability to rise superior to every difficulty, thanks to his defiance and power of will. Humanly it is hard to understand how all attacks and defeats only served to embolden him. Protestants have spoken of the “demoniacal greatness” manifest in Luther, have called him a man of “huge proportions and power” in whose “breast two worlds wrestled,” and, on account of his “heroic character,” have even claimed that history should overlook “the vices proper to heroes.”[878]
