He was constantly dreaming of work, calculating the hours and the lines necessary to pay his debts: two months or more. But that was all, and the work was never begun.159
Proud, misanthropic, and apathetic, he said of himself: “Discontented with others and discontented with myself, I desire to redeem myself, to regard myself with a little pride in the silence and solitude of the night. Souls of those I have loved, souls of those I have sung, strengthen me, sustain me, remove from me the lies and the corrupting vapours of the world; and thou, O Lord my God, grant me grace to produce some fine lines which will prove to myself that I am not the last of men, that I am not inferior to those whom I contemn.”160
And he had need of it, for he called Gustave Planche imbecile, Dumas a farceur, Sue stupid, Féval an idiot, George Sand a Veuillot without delicacy. What he attacked in all these writers was the fame he wished to possess; that is why he made fun of Molière and Voltaire.
With the progress of insanity he used to invert words, saying “shut” when he meant to say “open,” &c. He died of progressive general paralysis of the insane, of which his excessive ambition was already a fore-running symptom.
Concato was the son of a poor tailor, the victim of grave cerebral affections. He himself presented certain characters of degeneration, such as pallor and large cheek bones; during many years he was subject to various forms of insanity. At the age of seventeen he was seized by the terror of sudden death, and provided himself with nitre to prevent future cerebral crises. At twenty he resolved to become a monk, although in childhood he had been so little devout that he had fabricated false notes of confession. Afterwards he quarrelled with an Austrian officer, and then became afraid of all sentinels and soldiers. He would never allow an officer to enter his house with his sword by his side; and even in old age trembled at the sight of one of the city guards. One night he dreamt he had committed a homicide, and for many days he was a prey to strange terrors. He suffered from claustrophobia: woe to whomsoever tried to lock him up in a carriage or a room! There were some days during which he considered himself the lowest of men. He was so irascible that he used to say that, to be in good health, one must be angry at least once a day. Yet he was one of the greatest of European physicians.161
Mainländer had a grandfather who, after the death of a son, carried religious mysticism to the extent of insanity, and died of inflammation of the brain at the age of thirty-three. A brother, also insane, wished to embrace Buddhism. As a youth, looking at the sea at Sorrento, he felt impelled to throw himself in, merely attracted by the purity of the water. He educated himself and wrote his celebrated book, Die Philosophie der Erlösung, but to realize his theories entirely, he adopted a rule of absolute chastity, and on the day on which his book was published hanged himself, the better to confirm a passage which said: “In order that man may be redeemed it is necessary that he should recognize the value of not-being, and desire intensely not to be.”162
The great Auguste Comte, the initiator of the positivist philosophy, was for ten years under the care of Esquirol, the famous alienist; he recovered, but only to repudiate, without any cause, the wife who had saved him; later, he – who had wished to abolish all priest-craft – believed himself the priest and apostle of a materialistic religion. In his works, amidst stupendous elucubrations, genuinely maniacal ideas may be found, as, for example, the prophecy that one day women will be fecundated without the help of the male.163
It is said that mathematicians are exempt from psychical derangements, but this is not true; it is sufficient to recall not only Newton and Enfantin, of whom I will speak at length, but the two famous distractions of Archimedes, the hallucination of Pascal, and the vagaries of the mathematician Codazzi (not to be confounded with Codazza). Codazzi was sub-microcephalic, oxycephalic, alcoholic, sordidly avaricious; to affective insensibility he added vanity so great that while still young he set apart a sum for his own funeral monument, and refused the least help to his starving parents; he admitted no discussion of his judgment even if it only concerned the cut of a coat; and he had taken it into his head that he could compose melodic music with the help of the calculus.
All mathematicians admire the great geometer Bolyai, whose eccentricities were of an insane character; thus he provoked thirteen officials to duels and fought with them, and between each duel he played the violin, the only piece of furniture in his house; when pensioned he printed his own funeral card with a blank date, and constructed his own coffin – a vagary which I have found in two other mathematicians who died in recent years. Six years later he had a similar funeral card printed, to substitute for the other which he had not been able to use. He imposed on his heir the obligation to plant on his grave an apple-tree, in remembrance of Eve, of Paris, and of Newton.164 Such was the great reformer of Euclid.
Cardan, called by his contemporaries the greatest of men and the most foolish of children – Cardan, who first dared to criticise Galen, to exclude fire from the number of the elements, and to call witches and saints insane – this great Cardan was the son, cousin, and father of lunatics, and himself a lunatic all his life. “A stammerer, impotent, with little memory or knowledge,” he himself wrote, “I have suffered since childhood from hypno-fantastic hallucinations.” Sometimes it was a cock which spoke to him in a human voice; sometimes Tartarus, full of bones, which displayed itself before him. Whatever he imagined, he could see before him as a real object. From the age of nineteen to that of twenty-six, a genius, similar to one which already protected his father, gave him advice and revealed the future. When he had reached the age of twenty-six he was not altogether deprived of supernatural aid; a recipe which was not quite right forgot one day the laws of gravity, and rose to his table to warn him of the error he was about to commit.165
He was hypochondriacal, and imagined he had contracted all the diseases that he read of: palpitation, sitophobia, diarrhœa, enuresis, podagra, hernia – all these diseases vanished without treatment, or with a prayer to the Virgin. Sometimes his flesh smelled of sulphur, of extinguished wax; sometimes he saw flames and phantoms appear in the midst of violent earthquakes, while his friends perceived nothing. Persecuted by every government, surrounded by a forest of enemies, whom he knew neither by name nor by sight, but who, as he believed, in order to afflict and dishonour him, had condemned his much-loved son, he ended by believing himself poisoned by the professors of the University of Pavia, who had invited him for this purpose. If he escapes from their hands, he owes it to the help of St. Martin and of
