To pass now to some older Catholic writers. In 1874 Bruno Schön, of Vienna, published an essay in which he depicted Luther as mentally deranged.[579]

The author, who was chaplain to a lunatic asylum, was not merely no historian and still less an expert in mental disease, but lacked even a proper acquaintance with Luther’s life and writings. His historical groundwork he took from second-rate works, and his opinion was biassed by his conviction that Luther could not but be insane. He makes no real attempt to prove such a thing; all he does is to give us an account, clothed in psychiatric terminology, of the different forms of madness from which Luther suffered; in the first place he was afflicted with megalomania and the mania of persecution, two forms of insanity frequently found together.—But nervous irritability, anxiety, moodiness, excitability, a too high opinion of himself, perversion of judgment and even hallucinations—could such be proved in Luther’s case—all these would not entitle us to say that he was ever really insane. Nervous derangement, says Kirchhoff, is not psychosis, and people subject to hallucinations are not always insane.[580]

Long before this other Catholic writers had instanced certain peculiarities in Luther’s mental state, though they, like almost all recent writers, with the exception of Hausrath, were ignorant of one of the most remarkable elements to be taken into consideration, viz. the fits of terror to which Luther had been subject from early youth. The treatment of this matter was made all the harder by the fact that Luther’s extravagant after-accounts of his life in the monastery, and the growth of his ideas, were received with too much credulity, and that his letters, his Table-Talk and many details of his life were but little known.

Maximilian Prechtl, Abbot of Michaelfeld (†1832), though he refuses to regard Luther as insane, nevertheless calls attention to the many “phantoms of a sick brain” which he had seen; “Luther believed,” so he says, “that he often saw the devil, and that under different shapes.”[581] The learned Abbot brought out a new annotated edition of Luther’s “Against the Papacy founded by the Devil,” which he published at the time of the Reformation-Festival in 1817, in order to show the mad fury, hate and mental confusion to which its author had fallen a victim. Luther’s writing betrays, so he opines, “no common fury but the insane passion of the man, then almost at death’s door.”[582] Too great stress must not be laid on some of the opinions he here advances, which overstep the limits he himself had traced and appear to credit Luther with insanity. Prechtl spoke out more strongly in his “Rejoinder” to the attacks made on his remarks. He emphasises “the incontrovertible proofs” to be found in Luther “of a troubled fancy,” and asserts that “he was not always in his right mind.”

Somewhat earlier, in 1810, the Catholic layman Friedrich von Kerz, who continued Stolberg’s “Geschichte der Religion Christi,” published a book “Über den Geist und die Folgen der Reformation” in which he comes to a far too unfavourable opinion of Luther’s mental state, which he seeks to bolster up by statements incapable of historical proof. In a nutshell, what he tentatively advances is, that, “owing to the shock following the death of a friend struck down at his side, Luther had lost his reason”; “the symptoms of a twisted mind soon became apparent.” “Luther not seldom appears in the light of an inexplicable moral enigma, so that we are led, not indeed willingly, to wonder whether a certain recurrent mental aberration and periodic madness was not in reality the first and perhaps the only source of his vocation as a Reformer, of all his public acts and of the greater part of his reforms.”[583]

As against Kerz, Schön and even Prechtl, we must urge that we have no proof that Luther was actually the slave of his morbid fancies, or mentally diseased; no such proof to support the hypothesis of insanity is adduced by any of the writers named. Of the temporary clouding of the mind they make no mention.

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.

We cannot too much impress on those who may be inclined to assume that, at least at times, Luther was not in his right mind the huge and truly astounding powers of work displayed by the man. Only comparatively seldom do we hear of his being disinclined to labour or incapable of work, and almost always the reason is clear. Even were the advocates of intermittent insanity ready to allow the existence of lengthy lucid intervals still so extraordinary a power for work would prevent our agreeing with them any more than with Schön, Möbius, Hausrath and the older authors referred to above.

As to the question of the possibility of such a disability having been inherited either from his father or his mother—a matter into which modern psychiaters are always anxious to inquire: Here, again, we find nothing to support the theory of mental derangement. Hans Luther, his father, was a stern, rude man of violent temper, and his wife, Margaret, would also appear to have been a harsh woman, without any joy in life and displaying small traces of the more winning traits of affection. Neither of the pair did much to sweeten the lad’s hard boyhood and youth. This certainly explains to some extent the thread of depression and pessimism which runs side by side with the lively and more cheerful one in the monk and university professor. Of greater importance to the question in hand is the irritability and violence of temper which showed itself in his father. If the latter really committed manslaughter in a fit of anger, as seems probable, and as has also been admitted by Protestant scholars,[584] then the son’s irritability, and his startling tendency to break out into foaming rage against his opponents, may doubtless be traced back in part to the effects of heredity. In 1906 the fact came to light that another Hans Luther, besides Martin’s father, resided at Mansfeld, and the latter, according to the records of the law-courts, would appear to have borne a bad character and to have been frequently punished for brawling and for being too ready with his knife. If the latter, as the name would imply, was a relative of Martin’s we have here one more argument to prove that the family was exceptionally irritable.[585]
