The first time that Alfieri heard music he experienced as it were a dazzling in his eyes and ears. He passed several days in a strange but agreeable melancholy; there was an efflorescence of fantastic ideas; at that moment he could have written poetry if he had known how, and expressed sentiments if he had had any to express. He concludes, with Sterne, Rousseau, and George Sand, that “there is nothing which agitates the soul with such unconquerable force as musical sounds.” Berlioz has described his emotions on hearing beautiful music: first, a sensation of voluptuous ecstasy, immediately followed by general agitation with palpitation, oppression, sobbing, trembling, sometimes terminating with a kind of fainting fit. Malibran, on first hearing Beethoven’s symphony in C minor, had a convulsive attack and had to be taken out of the hall. Musset, Goncourt, Flaubert, Carlyle had so delicate a perception of sounds that the noises of the streets and bells were insupportable to them; they were constantly changing their abodes to avoid these sounds, and at last fled in despair to the country.[70] Schopenhauer also hated noise.

Urquiza fainted on breathing the odour of a rose. Baudelaire had a very delicate sense of smell; he perceived the odour of women in dresses; he could not live in Belgium, he said, because the trees had no fragrance.

Guy de Maupassant says of Gustave Flaubert: “From his early childhood the distinctive features of his nature were a great naïveté and a horror of physical action. All his life he remained naïf and sedentary. It exasperated him to see people walking or moving about him, and he declared in his mordant, sonorous, always rather theatrical voice, that it was not philosophic. ‘One can only think and write seated,’ he said.”[71] Sterne wrote that intuition and sensibility are the only instruments of genius, the source of the delicious impressions which give a more brilliant colour to joy, and which make us weep with happiness. It is known that Alfieri and Foscolo often fell at the feet of women who were very unworthy of them. Alfieri could not eat on the day when his horse did not neigh. Every one knows that the beauty and love of the Fornarina inspired Raphael’s palette, but very few know that he also composed one hundred sonnets in her honour.[72]

Dante and Alfieri fell in love at nine years of age, Scarron at eight, Rousseau at eleven, Byron at eight. At sixteen Byron, hearing that his beloved was about to marry, almost fell into convulsions; he was almost suffocated and, although he had no idea of sex, he doubted if he ever loved so truly in later years. He had a convulsive attack, Moore tells us, on seeing Kean act. The painter Francia died of joy on seeing one of Raphael’s pictures. Ampère was so sensitive to the beauties of nature that he thought he would die of happiness on seeing the magnificent shores of Genoa. In one of his manuscripts he had left the journal of an unfortunate passion. Newton was so affected on discovering the solution of a problem that he was unable to continue his work. Gay-Lussac and Davy, after making a discovery, danced about in their slippers.

It is this exaggerated sensibility of men of genius, found in less degree in men of talent also, which causes great part of their real or imaginary misfortunes. “This precious gift,” writes Mantegazza, “this rare privilege of genius, brings in its train a morbid reaction to the smallest troubles from without; the slightest breeze, the faintest breath of the dog-days, becomes for these sensitive persons the rumpled rose-petal which will not let the unfortunate sybarite sleep.”[73] La Fontaine perhaps thought of himself when he wrote:—

Un souffle, une ombre, un rien leur donne la fièvre.

Offences which for others are but pin-pricks for them are sharpened daggers. When Foscolo heard a mocking word from one of his friends he became indignant, and said to her: “You wish to see me dead; I will break my skull at your feet”; so saying, he threw himself with great violence and lowered head against the edge of the marble mantlepiece; a charitable bystander promptly seized him by the collar of his coat, and saved his life by throwing him on the ground. Boileau and Chateaubriand could not hear any one praised, even their shoemakers, without a certain annoyance. Hence the manifestations of morbid vanity which often approximate men of genius to ambitious monomaniacs. Schopenhauer was furious and refused to pay his debts to any one who spelled his name with a double “p.” Barthez could not sleep with grief because in the printing of his Génie the accent on the ē was divided into two. Whiston said he ought not to have published his refutation of Newton’s chronology, as Newton was capable of killing him. Poushkin was seen one day in the crowded theatre, in a fit of jealousy, to bite the shoulder of the wife of the Governor-General, Countess Z., to whom he was then paying attention.

Any one who has had the rare fortune to live with men of genius is soon struck by the facility with which they misinterpret the acts of others, believe themselves persecuted, and find everywhere profound and infinite reasons for grief and melancholy. Their intellectual superiority contributes to this end, being equally adapted to discover new aspects of truth and to create imaginary ones, confirming their own painful illusions. It is true, also, that their intellectual superiority permits them to acquire and to express, regarding the nature of things, convictions different from those adopted by the majority, and to manifest them with an unshakeable firmness which increases the opposition and contrast.

But the principal cause of their melancholy and their misfortunes is the law of dynamism which rules in the nervous system. To an excessive expenditure and development of nervous force succeeds reaction or enfeeblement. It is permitted to no one to expend more than a certain quantity of force without being severely punished on the other side; that is why men of genius are so unequal in their productions. Melancholy, depression, timidity, egoism, are the prices of the sublime gifts of intellect, just as uterine catarrhs, impotence, and tabes dorsalis are the prices of sexual abuse, and gastritis of abuse of appetite.

Milli, after one of her eloquent improvisations which are worth the whole existence of a minor poet, falls into a state of paralysis which lasts several days. Mahomet after prophesying fell into a state of imbecility. “Three suras of the Koran,” he said one day to Abou-Bekr, “have been enough to whiten my hair.”[74] In short, I do not believe there has ever been a great man who, even at the height of his happiness, has not believed and proclaimed, even without cause, that he was unfortunate and persecuted, and who has not at some moment experienced the painful modifications of sensibility which are the foundation of melancholia.
