Even in his devotion to his studies and in his manner of writing on learned subjects his natural extravagance stands revealed. His love for study was all passion; his mode of thought and expression was simply grotesque. It was the young monk’s passion for learning which led him on the occasion of his visit to Rome to petition the Pope to be allowed for a term of several years to absent himself from home and devote himself in the garb of a secular priest to his studies at the Universities. At Wittenberg we find him in the refectory pen in hand in the silent watches of the night when all the other monks had gone to rest, and, in his excited state, he fancies he hears the devil making an uproar. Though, according to his admission of Oct. 26, 1516, he was so busy and overwhelmed with literary work, as “rarely to have time to recite the Hours or to say Mass,”[723] yet he still had time enough to inveigh against the “sophists of all the Universities” as he had, even then, begun to term the professors of his day. He professed his readiness, were it necessary, to find time to go to Erfurt in order to defend in a public disputation there the Theses set up at Wittenberg in his name by his pupil Franz Günther; the Erfurt Augustinians were not to denounce these propositions as “paradoxical, or actually cacodoxical,” “for they are merely orthodox.” “I wait with eagerness and interest to see what they will put forward against these our paradoxes.”[724] In April, 1517, when Carlstadt caused some commotion by publishing his erroneous views on nature and grace in 152 theses, Luther called them in one of his letters the paradoxes of an Augustine, excelling the doctrine in vogue as much as Christ excels Cicero; there were some who declared these propositions to be paradoxical rather than orthodox, but this was “shameless insolence” on the part of men who had studied and understood neither Augustine nor Paul; “to those who understand, however, the theses ring both pleasantly and beautifully, indeed to me they seem to have an excellent sound.”[725] His restless style and love of emphasis is characteristic of his own inner restlessness and excitement. He himself was quite aware of the source of this disquiet, at least so far as it was the result of a moral failing. In 1516 he lays his finger deliberately on his besetting fault when he admits to a friend, that the “root of all our unrest is nowhere else to be found than in our belief in our own wisdom”; “I have been taught by my own experience! Oh, with how much misery has this evil eye [belief in my own wisdom] plagued me even to this very day!”[726]
