As for the kind of megalomania met with in Luther, when he insists on his being the mouthpiece of revelation, this is not the sort usual in the case of the mentally deranged, when the patient appears to be held captive under the spell of his delusion. Luther often wavered in his statements regarding his special revelation, indeed sometimes went so far as to deny it; in other words he was open to doubt. Moreover, at the very times when he clung (or professed to cling) to it with the greatest self-complacency, he was suffering from severe attacks of depression, whereas it is not usual for megalomania and depression to exist side by side. As for the periodic fits of insanity suggested by Hausrath his moods alternated too rapidly. His morbid ideas do not constitute a paranoic system of madness, and still less is it possible to attribute everything to mere hypochondriacal lunacy. The theory of Luther’s not being a free agent is excluded not only by his doubts and remorse of conscience, but also by the bitter determination with which at the very beginning he persuades himself of his ideas, insists upon them later when doubts arise, and finally surrenders himself to their spell by systematic self-deception. Such behaviour does not accord with that of a man who is not free. It must also be noted that the morbid symptoms of which Schön speaks, in whatever light they be regarded, do not occur simultaneously; some disappear while others become more marked as time goes on. This, however, also makes it difficult and wellnigh impossible to discover what were the components which originally went to make up Luther’s mentality before it had been seared by the errors and inward commotion of his later passionate life. Above all a fact repeatedly pointed out already must not be overlooked, viz. that, throughout, wilful giving way to passion, lack of self-control and too high an opinion of himself, united with self-deception played a great part with him, particularly in those outbreaks of fury against Pope and Papists in which one might be tempted to see the work of a maniac. In view of Luther’s aptitude to pass rapidly from craven fear to humorous self-confidence it would be necessary in order to prove his insanity, to show clearly as far as possible—a demonstration which has not yet been attempted—that periods of depression or fear really alternated with periods of exaltation, and what the duration of these periods was.
