Krebs was much less complicated, and notably narrower in the frontal region. The frontal convolutions were also inferior in development to those of Gauss; and the anterior lobes were voluminous in another celebrated mathematician, Professor De Morgan, whose brain is in Bastian’s possession.35
Stammering.– Men of genius frequently stammer. I will mention: Aristotle, Æsop, Demosthenes, Alcibiades, Cato of Utica, Virgil, Manzoni, Erasmus, Malherbe, C. Lamb, Turenne, Erasmus and Charles Darwin, Moses Mendelssohn, Charles V., Romiti, Cardan, Tartaglia.
Lefthandedness.– Many have been left-handed. Such were: Tiberius, Sebastian del Piombo, Michelangelo, Fléchier, Nigra, Buhl, Raphael of Montelupo, Bertillon. Leonardo da Vinci sketched rapidly with his left hand any figures which struck him, and only employed the right hand for those which were the mature result of his contemplation; for this reason his friends were persuaded that he only wrote with the left hand.36 Mancinism or leftsidedness is to-day regarded as a character of atavism and degeneration.37
Sterility.– Many great men have remained bachelors; others, although married, have had no children. “The noblest works and foundations,” said Bacon,38 “have proceeded from childless men, which have sought to express the images of their minds, where those of their bodies have failed. So the care of posterity is most in them that have no posterity.” And La Bruyère said, “These men have neither ancestors nor descendants; they themselves form their entire posterity.”
Croker, in his edition of Boswell, remarks that all the great English poets had no posterity. He names Shakespeare, Ben Jonson, Milton, Otway, Dryden, Rowe, Addison, Pope, Swift, Gay, Johnson, Goldsmith, Cowper. Hobbes, Camden, and many others, avoided marriage in order to have more time to devote to study. Michelangelo said, “I have more than enough of a wife in my art.” Among celibates may be mentioned also: Kant, Newton, Pitt, Fox, Fontenelle, Beethoven, Gassendi, Galileo, Descartes, Locke, Spinoza, Bayle, Leibnitz, Malebranche, Gray, Dalton, Hume, Gibbon, Macaulay, Lamb, Bentham, Leonardo da Vinci, Copernicus, Reynolds, Handel, Mendelssohn, Meyerbeer, Schopenhauer, Camoëns, Voltaire, Chateaubriand, Flaubert, Foscolo, Alfieri, Cavour, Pellico, Mazzini, Aleardi, Guerrazzi. And among women: Florence Nightingale, Catherine Stanley, Gaetana Agnesi (the mathematician), and Luigia Laura Bassi. A very large number of married men of genius have not been happy in marriage: Shakespeare, Dante, Marzolo, Byron, Coleridge, Addison, Landor, Carlyle, Ary Scheffer, Rovani, A. Comte, Haydn, Milton, Sterne, Dickens, &c. St. Paul boasted of his absolute continence; Cavendish altogether lacked the sexual instinct, and had a morbid antipathy to women. Flaubert wrote to George Sand: “The muse, however intractable, gives fewer sorrows than woman. I cannot reconcile one with the other. One must choose.”39 Adam Smith said he reserved his gallantry for his books. Chamfort, the misanthrope, wrote: “If men followed the guidance of reason no one would marry; for my own part, I will have nothing to do with it, lest I should have a son like myself.” A French poet has said:
“Les grands esprits, d’ailleurs très-estimables,
Ont très peu de talent pour former leurs semblables.”40
Unlikeness to Parents.– Nearly all men of genius have differed as much from their fathers as from their mothers (Foscolo, Michelangelo, Giotto, Haydn, &c.). That is one of the marks of degeneration. For this reason one notes physical resemblances between men of genius belonging to very different races and epochs; for example, Julius Cæsar, Napoleon, and Giovanni of the Black Bands; or Casti, Sterne, and Voltaire. They often differ from their national type. They differ by the possession of noble and almost superhuman characters (elevation of the forehead, notable development of the nose and of the head, great vivacity of the eyes); while the cretin, the criminal, and often the lunatic, differ by the possession of ignoble features: Humboldt, Virchow, Bismarck, Helmholtz, and Holtzendorf, do not show a German physiognomy. Byron was English neither in his face nor in his character; Manin did not show the Venetian type; Alfieri and d’Azeglio had neither the Piedmontese character nor face. Carducci’s face is not Italian. Nevertheless, one finds very notable and frequent exceptions. Michelangelo, Leonardo da Vinci, Raphael, and Cellini, presented the Italian type.
Precocity.– Another character common to genius and to insanity, especially moral insanity, is precocity. Dante, when nine years of age, wrote a sonnet to Beatrice; Tasso wrote verses at ten. Pascal and Comte were great thinkers at the age of thirteen, Fornier at fifteen, Niebuhr at seven, Jonathan Edwards at twelve, Michelangelo at nineteen, Gassendi, the Little Doctor, at four, Bossuet at twelve, and Voltaire at thirteen. Pico de la Mirandola knew Latin, Greek, Hebrew, Chaldee, and Arabic, in his childhood; Goethe wrote a story in seven languages when he was scarcely ten; Wieland knew Latin at seven, meditated an epic poem at thirteen, and at sixteen published his poem, Die Vollkommenste Welt. Lopez de la Vega composed his first verses at twelve, Calderon at thirteen. Kotzebue was trying to write comedies at seven, and at eighteen his first tragedy was acted. Schiller was only nineteen when his epoch-making Räuber appeared. Victor Hugo composed Irtamène at fifteen, and at twenty had already published Han d’Islande, Bug-Jargal, and the first volume of Odes et Ballades; Lamennais at sixteen dictated the Paroles d’un Croyant. Pope wrote his ode to Solitude at twelve and his Pastorals at sixteen. Byron wrote verses at twelve, and at eighteen published his Hours of Idleness. Moore translated Anacreon at thirteen. Meyerbeer at five played excellently on the piano. Claude Joseph Vernet drew very well at four, and at twenty was already a celebrated painter. At thirteen Wren invented an astronomical instrument and offered it to his father with a Latin dedication. Ascoli at fifteen published a book on the relation of the dialects of Wallachia and Friuli. Metastasio improvised at ten; Ennius Quirinus Visconti excited the admiration of all at sixteen months, and preached when six years old. At fifteen Fénelon preached at Paris before a select audience; Wetton at five could read and translate Latin, Greek, and Hebrew, and at ten knew Chaldee, Syriac, and Arabic. Mirabeau preached at three and published books at ten. Handel composed a mass at thirteen, at seventeen Corinda and Nero, and at nineteen was director of the opera at Hamburg. Raphael was famous at fourteen. Restif de la Bretonne had already read much at four; at eleven he had seduced young girls, and at fourteen had composed a poem on his first twelve mistresses. Eichorn, Mozart, and Eybler gave concerts at six. At thirteen Beethoven composed three sonatas. Weber was only fourteen when his first opera, Das Waldmädchen, was represented. Cherubini at thirteen wrote a mass which filled his fellow-citizens with enthusiasm. Bacon conceived the Novum Organum at fifteen. Charles XII. manifested his great designs at the age of eighteen.41
This precocity is morbid and atavistic; it may be observed among all savages. The proverb, “A man who has genius at five is mad at fifteen” is often verified in asylums.42 The children of the insane are often precocious. Savage knew an insane woman whose children could play classical music before the age of six, and other children who at a tender age displayed the passions of grown men. Among the children of the insane are often revealed aptitudes and tastes – chiefly for music, the arts, and
